2. Sorghum: In order to meet the nutrient requirements of sorghum from jointing to heading, the first fertilizer should be applied at the jointing stage, 150-225 kg of ammonium carbonate or 120-180 kg of urea per hectare; Apply a second fertilizer, 120 kg of ammonium carbonate or 75 kg of urea per hectare.
3. Soybeans: Soybeans are crops that require more nitrogen fertilizer. They are usually applied once during the initial flowering stage of soybeans. This can reduce the rate of falling flowers and pods, and can prolong the life of plants, increase grain weight, increase yield, and can be traced per hectare. Apply 150-225 kg of ammonium carbonate or 120-180 kg of urea; in the pod-forming stage of soybean, one-time top dressing can be carried out, and the effect of increasing yield is more obvious.
Fourth, sunflower: planting sunflower in addition to applying fertilizer. Generally, topdressing is carried out in the bud stage, and 225 kg of ammonium carbonate or 180 kg of urea are applied in hectares. Conditional farmers can also carry out a root dressing during the flowering period.
Fifth, castor: timely application of ramie topdressing, can promote ramie early maturity and high yield. The first top dressing can be combined with fixed seedlings. Each hectare has 225 kg of ammonium carbonate or 180 kg of urea. The second top dressing is carried out before the flowering of the castor. Phosphate is the main factor, which can increase the yield.
1. Corn: After the jointing to the Dagukou period, it is the peak period for absorbing nutrients. Generally, the first fertilizer can be applied before and after jointing. 150 kg of ammonium nitrate or 120 kg of urea can be applied per hectare. 7-10 days, the second fertilizer should be applied, and 225 kg of ammonium nitrate or 180 kg of urea can be applied per hectare. If the base fertilizer and seed fertilizer are sufficient and the soil is very fertile, one can concentrate the top dressing and combine the second shovel for deep fertilization.
