我们公社每年在冬小麦田套种玉米4,000多亩,产量高低对全年粮食总产量影响很大。套种玉米亩产量高的可达800来斤,低的只有200来斤。高产原因很多,主要是抓好了以下五条。 1.浇好出苗水。套种玉米增产的关键是早种早出苗,冬小麦生长后期需水量很大,套种玉米如墒情稍差,即影响全苗。东冷大队社员郭永林小满套种玉米,播后三天浇水,因为供水不足只浇了一半。到6月11日,浇过水的苗高50厘米,没浇上水的还未出苗,6月12日下雨,16日才全苗。20日每亩追碳铵100斤,出苗迟的又偏施了人粪尿, Our commune interplaces 4,000 mu of corn every year in the winter wheat field. The yield level has a great impact on the annual grain output. Intercropping corn mu yield up to 800 pounds, low only 200 pounds. High yield for many reasons, mainly to grasp the following five. 1 pouring out of water. The key to the intercropping corn yield is early emergence of early seedlings, winter water demand is very large late, intercropping corn, such as moisture slightly less, that affect the whole seedlings. East cold brigade member Guo Yonglin Xiaoman sets of corn, watering three days after sowing, because only insufficient water supply was poured in half. To June 11, poured the water of the seedling height 50 cm, not pouring on the water has not yet emerged, June 12 rain, only 16 full seedlings. 20 per acre followed by 100 kg of ammonium bicarbonate, emergence of late but also the partial application of human waste,
