Vegetable garden soil is a fertile soil artificially cultivated. The excellent vegetable garden soil layer and ripening soil layer are deep, with good structure, high organic matter content, and strong water retention and fertilizer retention. After many years of cultivation, vegetable gardens tend to have an aging phenomenon, which is mainly manifested in the imbalance of the nutrients in the vegetable garden soil and a serious imbalance in the proportion of the soil. The cropping layer becomes shallow, the granule structure is destroyed, the soil acidification, and the soil fertility gradually decline, which seriously affects the vegetable production. The reasons for the aging of vegetable garden soil can be taken to prevent and control: Enramycin Feed Additives,Enramycin Additives,Enramycin Growth Promoter,Enramycin Improve Feed Return Shandong Shengli Bioengineering Co., Ltd , https://www.shenglipharm.com
1. Advocate scientific fertilization. According to the fertility characteristics of different types of vegetables, fertilizer requirements, soil fertilizer status, and fertilizer types and nutrient content, scientifically calculate the amount of fertilizer, and according to different cultivation seasons and soil, water and other conditions flexible. Should be vigorously promote the field of fertilization techniques and soil testing and fertilization techniques. Using scientific fertilization methods, adhere to the combination of basal fertilizer and top dressing. Basal manure should be dominated by organic fertilizer, combined with the application of phosphorus and potassium fertilizers; top dressing should be top-dressed according to the different growth stages of vegetables and fertilizer requirements, focusing on the prosperous period of product organ formation such as rhizome, tuber enlargement period, knot ball During the period of flowering, the topdressing is applied again. Basal fertilizers should be applied deeply, applied in layers or in furrows. Top dressing should be done with watering. Promote foliar fertilization technology.
2, scientific use of chemical fertilizers. To strictly control the amount of chemical fertilizers in particular to reduce the amount of nitrogen fertilizers. Elimination of blind fertilization, indiscriminate application of fertilizer, and partial application of nitrogen fertilizer. Fertilizers must be selected not only for nutrient content, but also for fertilizers with low impurity content, especially heavy metals and toxic substances, and high-purity fertilizers. In addition, fertilizers that do not acidify the soil should be used as much as possible depending on the soil conditions. Pay attention to the use of nitrogen, phosphorus, and potassium fertilizers to eliminate the phenomenon of partial nitrogen fertilizer. Pay attention to the use of trace element fertilizers, popularize nitrogen, phosphorus and potassium compound fertilizers and organic and inorganic compound fertilizers.
3, vigorously promote the application of organic fertilizer. Organic fertilizers not only have full nutrients, they have long-lasting and stable fertilizer effects, and they have large buffering capacity. They are also rich in organic matter, they can improve soil structure, and have little pollution to the soil environment of vegetable fields. To vigorously advocate the use of organic fertilizers, it is necessary to use sufficient quality of livestock manure and other manures that have been fully decomposed and treated by accumulation and fermentation. Application of local conditions to promote the technology of returning straw and green manure in vegetable fields, both to increase the source of fertilizer can also improve the soil.
4, emphasis on training and improve soil fertility. Take comprehensive treatment measures such as the scientific rotation of crops, dry crops, melons and vegetables; expand the cultivation of legumes; increase the application of organic fertilizers; establish standardized vegetable fields, strengthen irrigation and water conservancy construction, and reduce the water table. Seriously acidic fields should be improved by adding lime or applying soil conditioners or improving soil fertility.
5, reduce the poisonous material pollution vegetable field. It is strictly prohibited to use garbage and sewage irrigation. In fields with high cadmium content, it can be used in rotation with rice to apply lime or calcium, magnesium and potassium fertilizers. Silicon and calcium fertilizers can increase soil pH.
