Abstract

The invention provides a close planting cultivating method for high-yield corn. The close planting cultivating method includes the steps of seed treatment, field planting, field management, weeding and water and fertilizer management. An excellent hybrid corn variety which is resistant to close planting, short in stalk, compact in plant type, capable of achieving straw staygreen, proper in mature period, free of baldness of clusters, resistant to lodging and resistant to diseases and pests is selected, rectangular land pieces are formed for planting, the width of the rectangular land pieces is 120-140 cm, the height of the rectangular land pieces is about 20 cm, the corn is planted in wide and narrow rows, the line spacing between the wide rows is 100-150 cm, the line spacing between the narrow rows is 40-50 cm, the distance between holes is 35-40 cm, three seedlings are planted in each hole, the treated seeds are sown in ditches in the mode that two seeds are planted at each point, the seeds are covered with soil while being sown, the soil is compacted after the seeds are covered with soil of one cun, and 5,700-6,700 seedlings are reserved per mu.

Description

technical field [0001] The invention relates to a high-yield cultivation method of corn, in particular to a high-yield corn close-planting cultivation method. Background technique [0002] my country is a populous country, and corn is one of the three major food crops. Corn production occupies a very important position in my country's agricultural production and national economy. The development of corn production has great practical significance for increasing farmers' income, ensuring national food security and even economic security. Although the total annual production of corn in my country has developed rapidly, the total annual production of corn is insufficient, and there is still a large gap with the market demand of my country's corn, and a large amount of imports is required every year. Affected by the lack of per capita agricultural land resources in my country and the adjustment of agricultural planting structure, it is difficult to expand the corn planting are...
