Corn empty stalks refer to the incompletely crushed kernels on the culms with no result spikes or ear development. There are many causes of empty stalks in maize, but it is mainly related to the availability of sufficient nutrients and moisture in the maize body during the differentiation and development of the ear. To sum up, there are mainly the following points: First, imbalances in nutrient supply and moisture supply can not meet the requirements during ear differentiation, resulting in weak and weak plants, yellow leaves, impaired female ear differentiation, and increased empty stalk ratio; The proportion of nutrient elements in the plant body is imbalanced, especially when there is less nitrogen and phosphorus deficiency and boron deficiency, the ear differentiation rate is slow, flowering is delayed, resulting in more empty stalks; third, the density is too large, the planting method is improper, the plant size is irregular, the field ventilation Poor light transmission, reduced photosynthesis of plants, affecting the supply of assimilation nutrients, making the ear unable to grow or can not be spit, also easily form empty stalks; Fourth, some varieties in the genetic characteristics of poor adaptability to cultivation conditions, in natural conditions and cultivation When conditions cannot meet the genetic requirements of a species, more empty culms also occur. To reduce the corn pole rate, you must do the following: First, use fine varieties. Choosing suitable high-yield and high-resistance varieties suitable for local planting is the primary measure to reduce the empty stalks of corn; the second is the rational close planting. Different varieties have their own suitable planting density. Our city vigorously promotes wide-narrow row planting (width-row 80cm, narrow-row 40cm) models. This model has better ventilation and light transmission in the field, and has higher light energy utilization rate and is beneficial to photosynthetic products. The formation of increased ear nutrition, and promote ear differentiation, so as to achieve a large number of ears, great, high yield; third is to strengthen field management. Appropriate application of fertilizers, organic fertilizers, balanced application of nitrogen, phosphorus and potassium fertilizers to achieve the combination of organic and inorganic fertilizers. In the maize seedling stage, strengthen management, control large seedlings, promote small seedlings, eliminate three types of seedlings, so that the maize population grows robust and neat. In the flowering pollination period, in the event of rainy weather, try to artificially pollinate. The fourth is to strengthen the construction of farmland irrigation and drainage facilities, improve the farmland infrastructure, and meet the energy discharge irrigation standards. Use groundwater irrigation to solve the problem of high temperature and drought.
