为了摸索玉米高产低成本的新途径,我们进行了玉米隔行去雄试验,获得了可喜的成果。去雄后的好处 1.提高产量 1974年公庄大队三亩平播玉米,高密度种植每亩7,000株,去雄三分之二,亩产1,068斤;1975年20亩试验田,每亩密度5,200株,去雄行亩产936斤,比不去雄行增产217斤,即增产30％。 2.空秆少,粒重、穗大去雄后植株变矮,中部叶片变宽,穗变长,特别是空秆率大大降低,而且粒数、千粒重都有所增加。 In order to explore a new way for high yield and low cost of maize, we carried out the interlaboratory debridement test and obtained gratifying results. The benefits of going to the mast 1. To increase production In 1974, three kilometers of Gongzhuang brigade sowed corn and planted 7,000 trees per mu at high density, removing two thirds to 1,068 kg per mu; in 1975, 20 mu of experimental field had a density of 5,200 trees per mu , Go to the male line yield 936 kg per mu, than not to increase output of 217 pounds male, that is, an increase of 30%. 2. Empty stalks less, grain weight, sprouting large plant becomes shorter, the central leaves widened, spike longer, especially empty stalk rate is greatly reduced, and the number of grains, 1000-grain weight has increased.
