良种是提高单位面积产量最经济、最有效的农业措施,在一般情况下,花生良种可增产10～20%。但花生用种量大、繁殖系数低,用普通大田栽培方法,繁殖系数通常只有用种量的10倍左右,致使新品种普及推广缓慢。因此,为了加速良种的普及推广,发挥良种在生产上的巨大作用,必须采用先进的栽培技术,提高良种种子的繁殖系数。其关键技术为:
Ancestral grazing is the most economical and effective agricultural measure to increase the yield per unit area. Under normal circumstances, the peanut seed can increase yield by 10-20%. However, with a large amount of peanut breeding, breeding coefficient is low, with ordinary field cultivation methods, the breeding coefficient is usually only about 10 times the amount of use, resulting in the promotion of new varieties of slow popularization. Therefore, in order to speed up popularization and promotion of elite seeds and bring into full play the great role of elite seeds in production, we must adopt advanced cultivation techniques to increase the breeding coefficient of elite seeds. The key technologies are:
