Fertility is a familiar term for farmers. As we all know, fertilizer is a substance that can provide the nutrients necessary for plant growth. These substances include nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, iron, manganese, aluminum, zinc, copper, and drills. One, several, or all of the various elements. However, when we have more choices for the increasing variety of fertilizer products, we are also faced with the need to raise awareness of the concept and content of fertilizers.
I. Fertilizer types and characteristics
There are different ways of classifying fertilizers, but this does not affect our understanding of various fertilizers and their characteristics. In this paper, the existing fertilizers are divided and described in the most general way.
1. Organic fertilizer Organic fertilizer can be understood as farmyard fertilizer, although at present, some organic fertilizers are no longer farm products. Organic manure is mainly made of organic matter (agricultural product waste and animal excrement). Therefore, it contains all the elements in the plant and is therefore nutritionally comprehensive. And because the proportion of these elements is not very high, coupled with the chemical binding or physical isolation of other substances, such as fibers and minerals, which accounts for a larger proportion, the fertilizer effect is relatively mild and lasting.
2. Inorganic Fertilizers Inorganic fertilizers can be understood as chemical fertilizers, including chemically synthesized (such as ammonium sulfate) and naturally occurring (such as rock phosphate), and organic urea is also often attributed to the scope of inorganic fertilizers. Inorganic fertilizers are characterized by only 1-2 nutrient elements (for example, urea only contains nitrogen, ammonium sulfate contains sulfur and nitrogen), and almost no impurities, so the effect of fertilizer is rapid (the process of urea conversion to ammonia, it is slightly slower 1 - 2 days) Significant but not long lasting, often due to insufficient dilution.
3. Compound fertilizer compound fertilizer basically belongs to the scope of inorganic fertilizer, but it contains more kinds of fertilizer elements than normal chemical fertilizers, which can be considered as a mixture of multiple chemical fertilizers. In general compound fertilizers, some non-fertilizer inert media are added to keep the various fertilizer ingredients stable, and they can be made into granules or powders through industrialized processing to facilitate their use.
4. Foliar fertilizers have undergone some important adjustments on the basis of compound fertilizers. On the basis of improving the solubility of compound fertilizers, in particular by adding certain substances, the fertilizer solution can be better adhered to the leaves or branches and It is easier to infiltrate the plant tissue to facilitate the absorption of the plant. In addition, it is also necessary to take care of the problem of burns and burns of high-concentration fertilizer solution due to evaporation of water after spraying.
5. Trace fertilizer Chemical fertilizers, which are mainly composed of micronutrients that are needed by plants but are in low demand, can be applied only when the plants do lack these trace elements.
6. Slow-release fertilizers Fertilizers that use special methods to reprocess fertilizers or compound fertilizers. Suspended release fertilizers are all solid particles in morphology. After being applied to soil, the fertilizer will slowly release its fertilizer components through the action of water and microorganisms, and it can be used once and for a long time. Since the release process is very slow, the amount released in a unit of time is very small, so the risk of plant fatal injury is small, and the utilization rate of fertilizer efficiency is high.
7. Special fertilizers add some or some substances, and they also have some other significant functions beyond fertilizers. Special fertilizers mainly include three types.
7.1, Biofertilizers contain live, specific types of beneficial bacteria, which can be introduced into the soil to introduce new microbial species or modify the soil microbial population balance. The main microorganisms included in these products are nitrogen-fixing bacteria, potassium-releasing or phosphorus-removing, and orchids.
7.2. Developmental regulation Fertilizers add phytohormones that can alter the normal development of the plant, such as promoting flowering and promoting tillering.
7.3, Pesticides Fertilizers have been supplemented with insecticide-killing or virus-inhibiting chemical preparations that play a role in maintaining root health during fertilization.
Second, orchid fertilizer
Although all the above types of fertilizers can be applied on orchids, the specific conditions need to be analyzed and treated separately to achieve the best results.
l. The basic principles of fertilization Many orchid friends have already mastered very well. For example, if the diseased grass is not applied and the dormancy period includes overheating, it is not applied, weak grasses are not applied or lessened, and strong grasses can be applied more appropriately; the amount of fertilizer to be applied should not be less, and the fertilizer should be applied more frequently; . The fertilization is also closely related to the nature of the cultivated plant material. It is necessary to comprehensively consider the fertilizer content and fertilizer retention of the plant material, and so on.
2. Organic Fertilizers and Inorganic Chemical Fertilizers Organic manures must be ripened and ripened. Microbes, fats, starches, sugars, and other substances, which are “high-grade nutrients†for microorganisms, are first digested by microorganisms. Only in this way, it will not lead to excessive proliferation of microorganisms within the root range of the bluegrass after fertilization and hinder the normal growth of bluegrass. Liquid organic fertilizers can be used as top dressings and applied during the growth of bluegrass. Solid organic fertilizers are mainly used as basal fertilizers. When planting bluegrass, they are used with good air permeability. Inorganic fertilizers can only be used as topdressing, of course, but to avoid the application of a single fertilizer, because the growth status of bluegrass is determined by the most lack of those fertilizer elements, the excess elements are either wasted or harmful.
3. The use of a single plant material for the micro-fertilizers, foliar fertilizers and slow-release fertilizers, and the absence of organic components in the plant material may easily lead to the lack of trace elements. In this case, the use of trace fertilizers often results in significant application effects. In general, the lack of a certain element of the plant will show some "symptoms." For example, iron is a component of chlorophyll, and due to poor mobility in the plant, when iron deficiency occurs, symptoms of green deficiency first appear on the veins of the seedlings of the tiller. Fertilizers are often used as foliar fertilizers and their effects are often better. For diseased grass and weak grasses, due to the poor absorption capacity of the root system, it is an appropriate choice to apply the fertilizer, preferably the compound fertilizer, to the foliar spray with an appropriate concentration of the aqueous solution. Although the application of slow-release fertilizers is also related to planting materials, in general, because of the slow growth of bluegrass, the demand for fertilizers is relatively small. Therefore, slow-release fertilizers are an ideal fertilizer type for planting bluegrass.
4. Special Fertilizers Special fertilizers have already had a large number of brands and types of products. Formerly the use of foreign products, such as the "Hyponex" series of Huabao, is a veteran formula fertilizer that has a history of several decades. In the last ten years or so, domestic specialty fertilizers have also developed rapidly.
4.1. Promoting Sprouted Fertilizers In general, the effects of special fertilizers that promote budding and sprouting are often significant. This is mainly due to the fact that there are many low-cost but relatively specific and strong effects that can promote the delivery of various plants. Cytokinin' hormones, as long as they are added to liquid fertilizers, can promote long seedlings, and for the more expensive orchid species, it is recommended to use this type of fertilizer to increase the seedling emergence rate. Yes, the amount of such fertilizers needs to be strictly controlled, or too many buds will be formed, excessive consumption of nutrients stored by the mother grass, and eventually no seedlings will be formed.
4.2. The promotion of flowering fertilizers is relatively effective in promoting sprouting fertilizers, and the effect of promoting the application of flowering fertilizers is often less pronounced. The main reason is that at present, there is no substance that has a special effect on the promotion of flowering. Moreover, flowering should be based on the physiological maturity of bluegrass, and the temperature, moisture content of the plant, light intensity, and even the length of sunshine. There are relationships. Although the promotion of flowering is necessary for the identification of varieties, participation in orchid exhibitions or home appreciation, it is a pity that such fertilizers often require multiple applications over a long period of time to be effective and require cooperation with other cultivation and management measures.
4.3, blue fungus fertilizer wild grass roots have symbiotic fungi, known as mycorrhizal fungi, commonly known as blue fungus. According to recent research data, the arbuscular mycorrhizal bacteria that can establish a symbiotic relationship with Lancao involve four categories of microbial fungal taxonomy, 7 classes, 14 purposes, and 50 genera. As far as species are concerned, there are even more. The blue fungus fertilizer has no need to use blue fungus fertilizer for orchids that have just gone down and orchid grass that grows normally. However, for diseased and sterilized roots that are sterile (sterilized) and cultured, blue fungus fertilizer is used. It is possible to achieve excellent results. Although there are many kinds of mycorrhizal fungi, only a few species with good adaptability are currently selected as the blue fungus in the blue fungus fertilizer. In general, the effect of the blue fungus fertilizer is closely related to the species of bacteria in the blue fungus fertilizer, the state of the strain (mycelium, spores) and the degree of activity, the solid or liquid environment of the blue fungus, and the like. It should be noted that Lancome Fertilizer is a living fertilizer. Too long a storage time and a high temperature in the storage environment will lead to a reduction in the effect. In special cases, the blue fungus may be dead in large quantities and endured by the harsh environment. The stronger other fungi replaced, and if so, the consequences of their application are hard to say.
Summary: There are many types of fertilizers that can be used in planting orchids. Only according to the actual conditions of the seedlings and planting materials, and the reasonable selection of the nature and characteristics of various fertilizers, can we exert the maximum effect of various fertilizers and obtain the best application effect.
Fertilizer type and orchid fertilizer
The factors affecting orchid growth include light, temperature, moisture (humidity and water quality), soil environment (breathability and fertilizer), and biological environment (insect and disease). In this factor of soil environment, air permeability is mainly determined by cultivated plant material, and the fertilizer component is directly related to the management of fertilization in peacetime in addition to planting materials. In recent years, due to the rapid development of plant nutrition science, which has promoted the innovation of fertilizer products, there have been many types of fertilizers with special properties and effects. This has also had a certain degree of influence on the conservative blues. How can we make use of the convenience brought about by the development of science and how can we rationally use new types of fertilizers to grow orchids better? This has become a real problem for the new generation of blues who do not want to stick to conventions.
