The reason why corn does not stick
In the process of growing corn, we will find that some corn does not draw tassels, which means that corn will not stick in the future, then what is the cause of it?
First, planted dense, poor ventilation and light transmission in the field, poor corn growth and development, impaired panicle differentiation, resulting in lack of lack of grain.
Second, sporadic or linear planting, the probability of female flower pollination decreased, corn is the same plant of different flowers, male flowers in the female flower in the next pollination distance.
Third, the water imbalance. The puffy bell-to-flowering stage is the critical period of corn water demand. In this period, the lack of water and drought will cause tassels to be drawn slowly or the dead tassels will die. This will lead to a significant reduction in pollen volume and a male-female imbalance. Drought and no rain before and after tasseling resulted in flowering of tassels and forward or late elongation of the female silking period. The flowering periods of the female and tassel were not encountered.
Fourth, when Yanghua Loose Powder encounters rainy weather, tassels do not bloom normally, and some pollen expands and breaks or sticks into groups and loses vitality, affecting the normal conduct of pollination and fertilization.
Fifth, pests and diseases. Corn grain is affected by corn borer, aphids, armyworm and leaf spot, smut, and other diseases and pests, leading to premature aging of functional leaves, and it also increases corn empty grains and severely forms empty spikes.
The lack of corn will cause farmers' friends to reduce production and income. In the face of the phenomenon of non-stick corn, farmers' friends can find out the reasons for prevention and control to reduce their own losses.
