Balanced fertilization can prevent corn empty stalk
When there is sufficient supply of nitrogen fertilizer and phosphorus and potassium are absent, the plants are likely to have dark green leaves, luxuriant stems and leaves, impaired sugar metabolism in the body, increased sugar content in the leaves and stalks, and a corresponding decrease in the sugar turning to the ear, making the ear of the female Undernutrition can not develop fruit spikes, easy to form corn empty stalks.
We must scientifically apply nitrogen, apply phosphorus and potassium fertilizers, supplement boron and zinc, and promote the development of flower organs. It is required that 25 to 30 kg of calcium phosphate and 5 to 7.5 kg of potassium be applied per acre, all for a single application of basal fertilizer. Nitrogen fertilizer should be lightly applied to Miaofei, skillfully applied for joint-fertilizer, and re-applied to attack manure, and Zhuo Shi applied fertilizer. 0.2% potassium phosphate monohydrate and 1%~2% urea solution can be used for extragranular spraying, once a week, 50~60kg nutrient solution per acre, spray 2~3 times, to extend the leaf functional period. To promote roots and strong stalks to meet the needs of young ear differentiation on nutrients.
