Early-maturing and dense-planting cultivation method for fresh maize

Abstract

The invention discloses an early-maturing and dense-planting cultivation method for fresh maize. The method includes the following steps that seed cultivation is performed, wherein heat preservation seedling cultivation is performed from mid-late February to early March in early spring; transplanting is conducted when each seedling grows 3-5 leaves, and the seedlings are transplanted in the groundfor heat preservation; planting is conducted, the transplanted seedlings are planted in holes, holes are formed at planting points, at least three seedlings are placed in each hole, the holes are filled with fertilizers before transplanting, and then full irrigation is performed; thermal insulation tools are removed gradually when the temperature rises due to environment warming; secondary seedling cultivation is performed in mid-early June, the seedling cultivation mode and the planting mode are same as these in spring; transplanting starts after preceding maize is harvested. According to the method, the maize can be planted in two seasons one year, meanwhile the centralized selling time of the maize is staggered, maize selling in a market can be advanced or delayed, lagging sales are avoided, and meanwhile the economic benefits are greatly improved. Meanwhile, the dense-planting in thin-hole technology is implemented, the labor and cost of transplanting are reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to an early-maturing dense-plant cultivation method suitable for two seasons of fresh corn in the north. Background technique [0002] Fresh corn is also called sweet corn, which can be eaten raw or cooked. The kernels of sweet corn are light yellow or milky white, soft and tender, and have 30% to 40% more protein than ordinary corn. And it is rich in various minerals and vitamins, as well as tryptophan, lysine and dietary fiber needed by the human body. In recent years, sweet corn has been favored due to its rich nutrition, good taste and high economic value. Corn growers have also developed a strong interest in it and planted it on a large scale in order to obtain higher economic benefits. [0003] In recent years, the supply of grain corn has exceeded the demand frequently, and the output value of ordinary grain corn is only about 1,000 yuan per mu, making it very ...
