河间县地处黑龙港流域,土壤瘠薄,水利资源紧缺。小麦常年种植面积在60万亩左右,其中21万亩属于旱薄盐碱地,占35％,使全县小麦产量长期处于低而不稳的状态。自1983年以来,我们对全县旱、薄、碱麦田在改进栽培技术措施上进行了一系列的试验、示范,取得了显著的成效。通过改进栽培技术措施,单产增加45公斤,平均增产率为35％。我们的作法是: 一、抓好蓄水和保墒。河间县年降水量56毫米,72％集中在夏季(七、八月份),小麦播种季节则干旱少雨。几年来我们在降雨季节对留麦地和带茬地采取了以方围埝、埝外挖沟(深20厘米)、埝内打畦的措施,既蓄纳了雨水,又控制了土壤养分的流失。雨后及时采取相应保墒措施,
Hejian County is located in Heilongjiang River Basin, barren soil, water resources in short supply. The perennial planting area of wheat is about 600,000 mu, of which 210,000 mu belongs to the drought-resistant saline-alkali land, accounting for 35% of the total output of wheat in the county. Since 1983, we have carried out a series of experiments and demonstrations on improved cultivation techniques in dry, thin and alkaline wheat fields in our county, and achieved remarkable results. By improving cultivation techniques and measures, yield increased 45 kg, the average yield was 35%. Our approach is: First, do a good job of water storage and conservation. Hejian County, the annual rainfall of 56 mm, 72% concentrated in the summer (July and August), wheat seeding season is dry. In recent years, during the rainy season, we have taken measures to encircle and leave stubble fields in the surrounding areas during the rainy season to dig trenches and trenches (20 cm deep). This measures not only contain rainwater but also soil nutrients Lost After the rain to take appropriate measures to conserve moisture,
