Why corn does not grain
There have been recent consultations with growers. Some corn headings do not have grain at the heading site and no corn muster above. What is the problem? The main reasons why corn does not have kernels are the following: One is the lack of nutrient supply during the ear ear differentiation. Second, the temperature is not suitable. Before and after the heading temperature higher than 35 °C, maize pollen was killed, affecting fertilization, resulting in failure to normal fruit. The temperature at the later stage of grouting maturation is lower than 16°C, which affects the accumulation of dry matter and causes pods. The third is water imbalance. From puffy to flowering stage is the critical period of corn water demand. During this period, the shortage of water and drought, commonly known as "card neck drought" and "card neck drought," will cause the tassel to pull out slowly or draw out the dead tassel, resulting in a large amount of pollen Reduced and unimpaired. Drought and no rain before and after tasseling, tassel flowering and early or late elongation of the female silking stage, and the flowering period of the female and tassels were not encountered. Fourth, when Yanghua Loose Powder encounters rainy weather, tassels do not bloom normally, and some pollen bulges or breaks into groups and loses vitality, affecting the normal conduct of pollination and fertilization. Fifth, the plants are too dense, poor ventilation and light transmission in the field, poor corn growth and development, and impaired ear differentiation, resulting in lack of grain and lack of grains. Sixth, pests and diseases. The corn kernels are affected by corn borers, aphids, armyworms, leaf spot diseases, smuts, and other pests, leading to premature aging of functional leaves, increasing empty grains of corn and severe empty ear formation.
