High-yield cultivation technique for summer corn

Abstract

The invention relates to a high-yield cultivation technique for summer corns and particularly introduces measures for summer corn high-yield cultivation from the aspects of purple sweet potato and summer corn seed selection, seed sowing, fertilization, field management and the like. High-yield summer corn varieties are selected. After wheat is harvested, early sowing against time is conducted. During sowing, five kilograms of diammonium phosphate and one kilogram of zinc sulfate are applied per mu land. During fertilization, seeds and fertilizers are required to be separated strictly to avoid the situation of seedling wilting. Then, water is sprayed to keep a full stand of seedlings. The seedlings are required to be thinned, complemented and fixed in time when three visible leaves grow from the corn seedlings. According to the condition of soil fertility, three times of additional fertilization are conducted at the seedling stage, the heading stage and the flowering to maturity stage of corns to ensure corn production, the corns are irrigated in time and attention is required to be paid to water drainage at a later stage. Decis, phoxim and the like are sprayed to prevent corn smut diseases, head smut, armyworms, corn borers, red spiders and the like. After the corns are ripe, the corns are required to be harvested and air-dried in time.

Description

technical field [0001] The invention relates to the field of planting, and specifically introduces various measures for planting summer corn from the aspects of summer corn seed selection, fertilization, seedling raising, field management and harvesting. Background technique [0002] Shandong is one of the largest concentrated production areas of summer maize in my country. However, according to the traditional cultivation methods, the average yield of summer maize in this area is still relatively low, and the potential for increasing the yield of high-yield maize is far from being brought into play. This is extremely inconsistent with favorable natural conditions. Therefore, combined with improved varieties, the implementation of supporting high-yield cultivation techniques in this area not only overcomes the shortcomings of traditional cultivation techniques, but also helps to give full play to the high-yield advantages of improved varieties.
