Embodiment Construction

[0017] The method for breeding new soybean varieties in space and the cultivation techniques of the present invention will be described in detail below through specific implementation methods:

[0018] A method for breeding new varieties of soybeans in space. This method is to return the soybeans of good varieties to the earth after being carried by a spacecraft from the earth to space, and use the micro-movement of space and the environment of high vacuum and strong radiation to make the soybeans carried by the spacecraft into space The seeds are mutated, and individuals with good comprehensive traits are selected from them, and then cultivated until several times of breeding, and a new variety with stable traits is selected, that is, a new space soybean variety is obtained. During the growth process of soybeans, spray the accelerator and control agent in three times: 5 days before flowering, the concentration is 800-1000 times; at the pod stage, the concentration is 500-600 t...

Abstract

The invention relates to a breeding method and cultivation technology of a new species of soybeans. The method is that the excellent species of soybeans is carried by spacecraft from Earth into space and then returned to Earth. Due to the space environment of micro-motion, high-vacuum and strong radiation, the soybeans carried by the spacecraft into space are mutated. Then the soybeans with good comprehensive traits are selected for nurturing until the new species with stable traits (i.e. the new species of space soybeans) are selected. The beneficial effects of this invention are: the expansion of the cultivation area of new species of soybeans can ease the tension in the contradiction between supply and demand of soybean and reduce the quantity of imported soybean and increase soybean production; meanwhile, the insecurity of the imported transgenic soybeans is reduced. The product index of the species can reach 667 square meters with 350-500 kg of output and increase production by 200 kg per Mu.

Description

technical field [0001] The invention relates to a breeding method and cultivation technique of a new soybean variety. Background technique [0002] my country is the country of origin of soybeans, with a history of soybean cultivation of more than 5,000 years. The comprehensive utilization value of soybean is higher than that of ordinary plants. Agricultural scientists in many countries in the world have carried out a lot of research and development on the new generation of soybean varieties. my country's soybean production has always been the first in the world. Later, due to my country's rapid population growth, limited land resources, low output value and cost ratio, and lagging production and cultivation techniques, the soybean planting area in my country has decreased, but the demand But keep increasing. At present, soybean production in my country's main producing areas may further shrink. In particular, concentrated soybean production areas a...
