In corn cultivation, the phenomenon of empty stalks is often found, and the severe stalk rate can reach about 30%, which has a great impact on the yield. The empty stalks of corn generally have two forms: one is complete empty culm, ie there is no ear at all; the other is that there are ear prototypes among the leaves, but their development is not completed. These two types can be divided into two types, the slim and the leggy.
There are many reasons for corn empty stalks, which are closely related to planting density, fertilization, meteorological conditions in the breeding process, and field management. In general, the higher the density, the higher the empty stalk rate, especially in the case of shallow ploughing and insufficient water and fertilizer. As the density is too large, the microclimate conditions of the farmland deteriorate, the plants are severely shaded, the nutrition area of ​​the individual plants is small, the received solar radiation energy is reduced, the photosynthesis intensity is reduced, and the roots are stunted, which affects the normal growth and development of the plants and causes empty stalks.
Insufficient fertilizer will also increase the emptying rate. However, in the case of too much nitrogen fertilizer, the vegetative organs of plants will grow too luxuriantly, causing contradiction between vegetative growth and reproductive growth. Because the plants are long and change the structure of the entire population, the microclimate of the farmland will also change, and the adverse conditions such as insufficient light will cause reproduction. The suppression of organ differentiation also increases the empty stalk rate.
During periods of corn ear formation and development, excessive drought, the ear can not pull out atrophy, or withdrawal can not be spinning. When the ear and ear were in the differentiation stage, they encountered rainy weather, lack of sunshine, and decreased photosynthesis intensity. In addition, poor long-term accumulation of water in the soil, poor absorption capacity of the roots, and nutritive substances that cannot meet the needs of the formation of the female ear can prevent the normal development of the ear after its differentiation or differentiation, resulting in empty culms.
