棉花单位面积产量的高低,决定于单位面积的株数,增加每株果枝数、果节数、成铃数和每铃籽棉的重量。这是棉花增产的主要途径。连年获得全省、全国先进生产单位光荣称号的浙江省慈溪县第二农场,1954年每亩留苗6,800株,平均亩产籽棉256斤,1955年每亩留苗7,000株,平均亩产籽棉278.5斤,1987每亩留苗7,140株,平均亩产籽棉500斤。当年场内第九小队有一块棉田8亩;其中一半每亩留苗7,000株,平均每株结铃13.9个,每亩结铃数97,300个,亩产籽棉493斤;另一半每亩留苗7,800株,平均每株结铃13.4个,每亩总铃数104,520个,亩产籽棉563斤。由此可见,合理地增加每亩
Cotton yield per unit area, depending on the number of plants per unit area, increase the number of fruit trees per plant, the number of fruit segments, the number of bolls and boll weight per bell. This is the main way for cotton to increase production. Lian Nianpi won the province, the honorary title of advanced production units in Cixi County, Zhejiang Province, the second farm in 1954 per mu acre Miao Miao 6,800, an average of 256 acres of seed cotton per kilogram, leaving 7,000 acres per mu in 1955, the average per acre seed cotton 278.5 Kg, 7,140 strains of seedlings per acre in 1987, the average yield of 500 kg of seed cotton. In that year, the ninth squad had 8 acres of cotton fields; half of them were 7,000 strains of seedlings per acre, with an average of 13.9 knots per plant, with 97,300 bolls per acre, 493 kg of seed cotton per mu, and 7,800 The average number of bolls per plant was 13.4, with 104,520 bolls per acre and 563 kg per mu of seed cotton. This shows that a reasonable increase in acre
