In addition to the factors of the variety itself, external factors are also the main causes of corn stalks: First, the climate factor. During the flowering and pollination period of maize, if encountering high temperature and drought weather, the male and female flowering stages encounter poorly, and the pollen and filaments have reduced viability, and they cannot normally endear; Loss of loose powder and empty stalks. The second is that the density is too large, resulting in the closure of the field, the individual thin, affecting the development of the ear. Third, extensive field management, lack of water and fertilizer, serious pests and weeds.
Measures to reduce the empty stalk of corn: appropriate close planting According to varieties, soil strength and cultivation methods, determine the appropriate planting density, make the field a good ventilation and light transmission, to meet the needs of the development of the ear nutrient.
Balanced fertilization, reasonable watering Soil testing and formulating fertilization, so that organic fertilizer and chemical fertilizer combined, and make-up application of trace fertilizer. Strengthen the jointing and booting period management, timely watering in high temperature and dry weather to meet the water needs of the female and tassels, timely drainage in rainy weather, and artificial pollination.
