Simple and effective root fertilization
Root fertilization is a common fertilization method. It involves dissolving nitrogen, phosphorus, potassium and other chemical fertilizers, trace element fertilizers, and human feces and urine in water, spraying them on the leaves of crops, and making the crops absorb and use. So it is also called leaf. Fertilization. The benefits of root-fertilization are many, mainly in: Fertilizer fast fertilizer dissolved in water sprayed on the leaves of the crop, more than 10 minutes to enter the meat, a few hours later to play a fertilizer effect. If the urea solution is sprayed on the cotton leaf surface, the leaves turn green from yellow to yellow after 3 days, and the root can be applied after 7 days. Fertilizer efficiency is generally higher at the roots, and the fertilizer utilization rate is only 25% to 70% in the current season, while the foliar spray is as high as 90%. Use less, fertilize evenly outside the fertilization, such as urea, but the amount of 667 square meters, but 1 to 1.5 kg, while the amount of top dressing is more than a few times, and it is difficult to apply uniform. The method is simple and convenient for external fertilization. It only needs to dissolve the fertilizer in water, and it can also be combined with the control of pests and chemicals and sprayed with chemical agents. While top-dressing is more troublesome, it can also cause mechanical damage to crops due to careless operation. The effect of yield increase is obvious, such as spraying 0.05% ammonium molybdate solution in the result period of peanut, which can increase production by more than 15%; corn spraying, spraying potassium dihydrogen phosphate and calcium superphosphate at the grain filling stage can promote grouting, increase grain weight, and increase production by 5%. ~7%. Particular attention should be paid to the fact that although the effect of external root fertilization is good, the amount of fertilization is limited, and the suction power of the foliage is not as good as the root. Therefore, it cannot replace the root dressing in the early stage of crop growth, and can only be used as an emergency or remedial measure to supplement the use.
