桔杆还田肥地增产,这是当前大面积种植,实行种地养地相结合,解决肥料不足,做到不断增产的重要措施之一。红星农场三大队一九七七年秋天翻压玉米杆三百亩,一九七八年种植春麦,亩产二百五十斤,千粒重三十一点九克,同时每亩收混播油菜三十斤,取得粮油双增产。在同样水肥管理和同样土质情况下,不是桔杆还田的地,春麦亩产只有一百多斤,单产相差一倍半。 他 们 的 做 法 开始搞桔杆还田时,他们有三怕:一怕犁地时玉米杆子压不下去;二怕烂不掉;三怕播种时畦埂打不起来。经过实践,这些顾虑都一一打消了。他们的做法是: 第一、准备桔杆还田的地,要先掰、先运、早誊地、早抢墒翻压,严防牲畜进地踏倒玉米杆,耕前要先把地两头玉米杆割倒四、五米宽,作为拖拉机转弯道。在搬运玉米的行道上开犁,并组织人力将割倒的玉米杆放进犁沟,不留空白点。 It is one of the important measures to solve the problem of insufficient fertilizer and increase production continuously. Red Star Farm third brigade in the autumn of 1977 turned over three hundred acres of corn stalks, planting spring wheat in 1978, yield two hundred and fifty pounds, one thousand three grain weight nineteen nine grams, at the same time per mu mixed sowing thirty Kg, made grain and oil double increase. In the same water and fertilizer management and the same soil conditions, not the straw back to the field, spring wheat mu yield of only 100 kilos, yield difference of one and a half times. When they began to practice their duties, they had three fears: one could not crush corn poles when they plowed; two could not afford to be rotten; After practice, these concerns have been eliminated one by one. Their approach is: First, to prepare the straw back to the field, we must first break, the first transport, as early as possible, early grab moisture pressure, prevent livestock into the corn stalks, before farming to ground two corn Bar cut four or five meters wide, as a tractor turns Road. Plow plows on the corns carrying the maize and organize manpower to cut the cut maize pits into the furrow without leaving a gap.
