为探索黄麻的合理群体结构,提高光能利用率,实现高产。我们从一九七七年开始,连续四年在白土公社进行宽窄行种植试验,即在平整地面后,按大行距十六至十八寸,小行距三至五寸,浅开三至五分的播种沟,条播种子,然后,每隔四至五个宽窄行,在宽行处开一条宽一尺、深五至六寸的排灌沟。定苗后株距二至三寸,四年平均亩产九百四十五点四斤。其中一九七九年和一九八○年,亩产突破千斤。比等距窄行种植法增产百分之十四至十六。增产原因是:一、提高土地利用率。利用面积达百分之八十六点六,比原来增加百分之十一点四到十三点二。二、提高收麻有效条数。每年每亩可定苗二万三千三百到二万四千四百株,收麻有效条数为一万七千三百到一万八
To explore the rational community structure of jute, improve the utilization of light energy and achieve high yield. Starting from 1977, we conducted plantation trials for wide and narrow rows at the Cotai Commune for four consecutive years. After leveling the ground, we walked 16 to 18 inches at major rows and 3 to 5 inches at small rows. Sowing seeds and sowing seeds. Then, every four to five wide and narrow rows, a wide-foot and deep-five to six-inch irrigation ditches are opened at wide rows. After Dingmiao plant spacing from two to three inches, four-year average yield of 94.5 kg. Among them, in 1979 and in 1980, the yield per mu exceeded the threshold. Than the equidistant narrow row planting method yield 14% to 16%. The reason for the increase is: First, improve land utilization. The utilization area reached 86.6%, an increase of 11.4% to 13.2% over the previous figure. Second, improve the effective number of closed Ma. Each acre can be set twenty-three thousand three hundred twenty-four thousand four hundred plants, the effective number of close to 17,300 to 18,000
