Method for cultivating space grass imitating super-space variation

The invention discloses a super-space variation imitating space grass cultivation method. Space grass cultivation is completed through second-stage cultivation, first-stage seed variation and second-stage plant optimization. The method specifically comprises the following steps: S1, seed pretreatment; s2, simulating super-space variation on the first-stage seed ground; s3, optimizing the second-stage plants to complete space grass cultivation. Traditional space breeding is shortened from four years and four generations to six months; the cost is reduced to 1%; the positive variation rate is increased by 600 per thousand from 1.5 per thousand; the space breeding efficiency is improved, the space breeding efficiency can be increased by hundreds and thousands of times on the ground, regeneration and fast growth are achieved, harvesting is conducted once every twenty days, and replanting is not needed for many years after one-time planting. The protein content of the space grass is three times of that of wheat, f
