Abstract

The present invention discloses a close-planting and high-yield cultivation method for maize. The method comprises the following steps: selecting an excellent hybrid maize variety to carry out wide-narrow row planting, wherein the row spacing is 17 cm, single particle seeding is used in seeding, and the seeding rate is 2.5-3 kg / 667 m<2>, and the seeding depth is 5-6 cm; applying an organic fertilizer during the deep ploughing process every autumn; applying 60 kg calcium-phosphorous fertilizer and 7 kg granular potassium fertilizer per 667 m<2> before seeding; performing furrow application of 10 kg diammonium phosphate per 667 m<2> after seeding; topdressing 15kg diammonium phosphate, 20 kg urea and 7kg granular potassium fertilizer per 667 m<2> after maize jointing; applying 25-30 kg urea and 7 kg granular potassium fertilizer per 667 m<2> at tasseling stage; applying 10-15 kg urea per 667 m<2> at 30-40 days after silking; spraying 20-30 mL maize roborant per 667 m<2> at maize jointing stage; preventing and controlling plant diseases and insect pests; and harvesting the maize. According to the close-planting and high-yield cultivation method for maize disclosed by the present invention, the maize yield per unit area can be improved.

Description

technical field [0001] The invention relates to the technical field of corn cultivation, in particular to a high-yield cultivation method for close-planting corn. Background technique [0002] Maize is one of the most widely distributed crops in the world, and it can be grown in a wide area from 58° north latitude to 40° south latitude. The economic value of corn is very high. It is not only the main food crop, but also an excellent feed, green feed and silage raw material for livestock. It is called the king of feed. In recent years, with the development of my country's animal husbandry, the planting area of ​​corn has increased day by day, and it has surpassed rice to become the food crop with the highest total output in my country. [0003] 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...
