Crops have the best topdressing period, and the topdressing effect is good in the best topdressing period.
Under the principle of balanced fertilization, the best topdressing period of corn is the peak period of nutrient absorption after the jointing to the big bell mouth. Generally, the first top dressing can be carried out before and after jointing, and 10 kg of urea per mu is applied. In the first 10 days, the second top dressing was carried out, and 20 kg of urea was applied per mu. If the base fertilizer and seed fertilizer are sufficient and the soil is very fertile, the fertilizer can be concentrated in one time.
The best topdressing stage of rice The absorption of nitrogen fertilizer by rice is gradually increased from the time of greening, and the peak of tillering is the peak period of sucking fertilizer. In order to promote early rice and early tillering, early application and heavy application of manure should be applied. Generally, 7 kg of urea can be applied per acre 7 days after transplanting, and 15-20 kg of urea can be applied after heading.
The best topdressing stage of peanuts The nutrient critical period of peanuts is in the early stage of fertility. About 15 days after the emergence of peanuts, the flower buds begin to differentiate and the nodules begin to form. When two pairs of side branches appear in the plant, the nitrogen fertilizer should be applied once in time, and the urea should be applied 5 to 10 kg per mu. After the peanut is flowered, it is combined with the soil and sprayed with multiple micro-fertilizers, which is beneficial to reduce the empty fruit rate and increase the peanut yield.
Soybean Best Topdressing Period Soybean is a crop that requires more nitrogen fertilizer, but it has a rhizobial nitrogen fixation that can solve some nitrogen sources. Usually, nitrogen fertilizer is applied once in the initial flowering stage of soybean, and generally 8 to 12 kg of urea is applied per acre. In the pod-forming period of soybean, a top dressing is carried out, and the multi-micro-fertilizer is sprayed on the foliar surface to increase the yield.
