Method for breeding space soybean new species and cultural technique

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...

At present, soybean production in my country's main producing areas may further shrink

In particular, concentrated soybean production areas are generally economically backward areas with poor natural conditions and few alternative crops. Soybean is a priority crop for the adjustment of agricultural planting structure in this area. However, due to the low yield of soybeans, the production efficiency has declined. Compared to its income is lower than that of corn
