高产是栽培的目的,合理密植是高产的中心。,在同样栽培管理的条件下,不同密度对作物生育和产量影响很大。特别是马铃薯等地下结薯的作物,由于营养面积不同,单株产量差异较大,直接影响群体产量的高低。我所1977年培创一亩高产田,亩产6000斤;并在4平方米营养面积中获得株产29斤的高产记录。1978 High yield is the purpose of cultivation, reasonable density is the center of high yield. Under the same cultivation and management conditions, different densities have a great impact on crop growth and yield. Especially potatoes and other underground tubers crop, due to different nutrient areas, large differences in individual plant output, a direct impact on the level of population output. In 1977, I cultivated a mu of high-yield field with a yield of 6,000 kg; and obtained a yield record of 29 pounds in 4 square meters of nutrition area. 1978
