河南淇县北阳乡东裴屯村青年农民裴会堂、梁巨福为了解决“三夏”中农活多,时间紧,劳力不足的问题,于1987年试验成功了前割后播的作业方法。具体做法是:采用11千瓦(15马力)的小四轮拖拉机(12马力也可以),前边悬挂割晒机收割小麦,后边牵引9行播种机播种大豆、玉米等秋粮作物。当年试种了200亩,增收大豆1万千克。1988年全村共播秋粮1800亩,其中1600亩采用了前割后播作业法,共增收大豆9万千克。1989～1991年共增收大豆30万千克。增产的因素如下: (1)小麦成熟前浇了灌浆水,地里有一定的墒情,保证了秋粮作物的发芽,且苗肥、苗壮、苗齐,为增产打下了基础。 (2)割下的小麦散在地里,盖满了地,减少了水分的蒸发,墒情好,促进了大豆生长,收了小麦,大豆已长出来了。 (3)两道工序一次完成,减少了
Henan Qi County Beiyang Township Peitun village youth farmer Pei Hall, Liang Jufu In order to solve the “three summer ” middle farmer, tight schedule, lack of labor issues, in 1987, the successful trial of the pre-cut after the broadcast method of operation . This is done by using a small four-wheeled tractor (12 horsepower) of 11 kW (12 horsepower) with the front windbreaker harvesting wheat and a 9-row seeder behind for sowing autumn crops such as soybeans and corn. In the same year, 200 mu of cultivated land was cultivated and 10,000 kg of soybean was added. In 1988 the village sowed 1,800 acres of autumn grain, of which 1,600 acres of pre-cut broadcast method of operation, a total increase of soybean 90000 kg. From 1989 to 1991 a total of 300,000 kg of soybean was added. Yield factors are as follows: (1) wheat irrigation before pouring grouting water, the ground has a certain moisture content to ensure the germination of autumn crops, and Miao Fei, Miao Zhuang, Miao Qi, laid the foundation for the increase. (2) The cut wheat scattered in the ground, covered with land, reducing the evaporation of moisture, good moisture, and promote the growth of soybeans, received wheat, soybeans have grown. (3) two processes completed at a time, reduced
