一九六五年我们在上双河分场三队调查了伏耕的增产幅度和灭苇效果.该队中一号地共400亩,加中心渠后分成二块条田.靠南的条田,一九六三年伏耕2次,一九六四年三次,两年共伏耕5次,靠北条田一九六三年未伏耕,一九六四年耕一次.两地所播冬小麦品种相同,又同时播种,播种时均施了种肥,一九六五年每亩又同样施化肥10公斤,管理上也基本一致.成熟时实割实测:南条田平均亩产456.68斤,北条田平均仅266.66斤.两年伏耕5次的比两年只伏新一次的增产71.27%,即每次伏耕增产小麦47.5斤.算算经济账,每伏耕一次,
In 1965, we investigated the yield increase and the reed effect of the cultivation of volts and tillands in the Shang Shuanghe sub-branch. The team of No. 1, a total of 400 acres, plus the central channel into two pieces of field. Tian, 1965 Fushui 2 times, 1964 three times, two years of total fertilizing 5 times, by the North Strip field 1963 without villiage, cultivated 1964. The two places The same winter sowing wheat varieties, but at the same time sowing, when planting were applied fertilizer, in 1965 and the same application of chemical fertilizer per kilogram 10 kg, management is basically the same. Mature real cut measured: South Strip average yield 456.68 kg , An average of only 266.66 kg Kitakyushu .Two years of fertilizing 5 times only two years of new yield increase of 71.27%, that is, 47.5 pounds of wheat per acre yield.Calculate the economic accounts, once per plowing,
