Two bogey for mixing fertilizer. Urea as a seed fertilizer can cause seeds to lose their germination power and can also endanger seedlings. At the same time, high concentrations of urea destroy the protein structure of the seed and are toxic and inhibitory to the seed.
Three bogey shallow application. Urea is easy to use and is easily consumed by weeds. The urea application depth is preferably 10-15 cm, and the fertilizer is applied to the soil, so that the fertilizer is in the moist soil layer, which is beneficial to the fertilizer effect.
Four bogey high-concentration foliar application. If the concentration of the foliar spray solution is too large, the leaves will burn out and affect the normal growth of the crop.
Five bogey late birth application. The application of urea in the late stage of crop growth is likely to cause crops to be late and ripe, affecting yield and normal harvest.
Six bogey single administration. Urea should be applied in combination with organic fertilizers and phosphorus and potassium fertilizers to meet the needs of crops for various nutrients. It can also accelerate the conversion and decomposition of urea, and is quickly absorbed by crops to improve urea utilization.
