Problems solved by technology

There is a large amount of corn planted in the south of Nanning, Guangxi. The local corn is traditionally harvested twice a year. During the corn planting period, the harvest period is mostly in high temperature and rainy weather, and the corn is easy to rot and deteriorate, causing losses and affecting the yield of corn. There is an urgent need to find a method of planting corn to solve the problem that corn is easy to rot and deteriorate during the local harvest period

Embodiment 1

[0033] 1) Selection of maize varieties: Zhengdan 958, a maize variety with a short growth period and capable of dense planting in spring, summer and autumn, was selected in the south of Nanning, Guangxi.

[0034] 2) Sowing: Spring sowing should be carried out on February 15th, summer sowing should be carried out on June 7th, and autumn sowing should be carried out on September 2nd. When summer sowing and autumn sowing are carried out, if the planting scale is large, the The corn that has not been harvested in one season is sown in the plot after harvesting while harvesting. The planting density of corn seeds is 60,000 plants / hm 2 .

[0035] Spring sowing, summer sowing and autumn sowing all adopt the double-plant sowing method with a wide row spacing of 90 cm and a narrow row spacing of 40 cm, and the double plants form a group, and the distance between adjacent two groups is 42 cm.

Abstract

The invention discloses a corn planting method. After corn is harvested each time, the corn is aired in the sunning ground which comprises an inverted-Y-shaped canopy frame formed by erecting bamboo poles. The longitudinal section of the inverted-Y-shaped canopy frame is in a triangle shape, the distance from the top end of the triangle to the bottom edge is 3.5 m, the bottom edge is 6 m long, and the bottom of the inverted-Y-shaped canopy frame is square and is 6 m wide. In the bottom, the length of the edge adjacent to the bottom edge is in direct proportion to the planting area of corn and is arranged to be 5m / hm<2>. The top and the periphery of the inverted-Y-shaped canopy frame are fixedly covered by thin films with the thickness being 8*10<-5>-15*10<-5> m. The closed sunning ground is arranged, the greenhouse function of the sunning ground greatly reduces the number of corn which mildews, rots and goes bad due to plum rains, loss of corn harvested each time is reduced, and the yield of corn is increased.
