Second, clever use of panicle fertilizer. Rice fertilizers that differentiated from young spikes to earing before heading were called "panicle fat." This period is the second peak of nitrogen absorption. Scientific application of panicle fertilizer can not only promote flower growth and grain growth, but also promote the role of large panicles and grains, and prevent the occurrence of greediness and lodging. There are several technical points to be made: First, the field is in good condition; the bottom is full; the morning leaves are not covered with dew; the leaves are straight at noon, and the leaves are yellowish; the third is cloudy. Shi, sunny day grab. The application time is rice round stalk period, urea 3-4 kg per mu, and with 0.2-0.3% potassium dihydrogen phosphate solution 50 kg per acre evenly sprayed on the foliage.
Third, if appropriate, apply fertilizer. The top-dressing fertilizer after heading rice is called "grain fertilizer", also known as "strong seed fertilizer." The application of granular fertilizer, as appropriate, can effectively extend the leaf functional period, prevent premature aging, and increase grain weight. However, it should be noted that if the seedlings are not yellow, they will not be applied in the rainy days, but there will be diseases in the fields. To select sunny afternoon spray 1% urea solution, or 1:500 times Huimanfeng active liquid fertilizer, spray 50 kg per mu. For the rice fields that have already suffered from sheath blight and rice-warm disease, use pesticides such as sclerotia net, different rice blast net, grain dry net, Nongkang 120, and chlorfluazuron to alternately spray and prevent and control in time.
Rice "Three Fats" and Its Application Techniques
First, timely application of fertilizer. The topdressing fertilizer before the rice is differentiated from transplanting to young spikes is called "pumping manure." The tiller fertilizer requires early application and sufficient quantity. Generally, the amount of fertilizer used accounts for 50-60% of the total amount of topdressing fertilizer. Because the tillering period is the first peak period of nitrogen absorption in rice, and because the temperature, water temperature, and soil temperature are low in the early stage of rice growth, the nutrient release is slow, and the amount of top dressing is too small to meet the needs of rice for nutrients. Only early and timely application will help rice deliveries early in the day and increase the number of tillers, reduce birthing points, and create conditions for competition for ear length and grain weight. The tillering fertilizer is applied 7-10 days after the rice is planted, and 5-7 kg of urea is applied per acre. Insufficient base fertilizer can be appropriately increased, but avoid excessive fertilizer, to prevent excessive growth in the middle and late, greedy green late.
