Planting method of re-planting soybean

Abstract

The invention relates to the soybean plantation, especially the replantation; the technical project of the invention to replant soybean is as following: cultivate the soybean seedlings for precocity, winter resistance, resisting drought and childbearing period about 84 days, and move them into farmland to ramify from rap roots and lateral roots and sizing, plant the second ones in the middle , and they can go on growing after the harvest of the first season ones. In Heilongjiang district, after the first season soybean, plant the second season soybean in the middle of the first one, and they can go on growing after the harvest of the first season ones. In Liaoning Province, if planted after the first ones have been harvested or before the mature, the second season soybean will have the fatness as follows: restisting high temperature, resisting drought, resisting ventitation, and prematurity and developed caulis. It can survive well in barren and ramify prosperously. This soybean grows flourish and mature in short time. The procreating period is 84 days, and all the active accumulated temperature is 1700 centigrade degrees. The method above can be used in south areas to harvest 3 times.

Description

technical field [0001] The invention relates to a method for planting soybeans, in particular to a method for planting soybeans again. Background technique [0002] At present, the growth period of soybeans is one season in the north every year, and two seasons in the south every year. Due to the change of natural climate, there is still a certain period of time before the frost period after harvesting soybeans. For this reason, seedlings are grown in advance, and the temperature in the greenhouse is used to reach the biological upper line of 11°C. The bean seedlings are in the greenhouse to generate effective active accumulated temperature. According to the field temperature can reach above 11°C, the bean seedlings are transplanted to the field. After the first season of soybeans is fixed, reseeding around the soybean roots or sowing in the middle of the bean seedlings to achieve the second season of production, there is no agricultural application of planting methods for r...

[0002] At present, the growth period of soybeans is one season in the north every year, and two seasons in the south every year. Due to the change of natural climate, there is still a certain period of time before the frost period after harvesting soybeans. For this reason, seedlings are grown in advance, and the temperature in the greenhouse is used to reach the biological upper line of 11°C. The bean seedlings are in the greenhouse to generate effective active accumulated temperature. According to the field temperature can reach above 11°C, the bean seedlings are transplanted to the field. After the first season of soybeans is fixed, reseeding around the soybean roots or sowing in the middle of the bean seedlings to achieve the second season of production, there is no agricultural application of planting methods for replanting soybeans in agricultural soybean planting. Therefore, Farmland has not generated greater economic value in the production process
