我县历年播种花生23万亩,小麦(麦套玉米)13万亩左右,由于在土地利用上长期以来存在着种植单一的现象,即中上等肥力的地多种植小麦(麦套玉米),瘠薄地多种植花生,造成了多年重茬连作,致使土壤有机质缺乏,养分比例失调,花生病虫害严重,为了提高粮油产量及土地的利用率,我们于1985—1986年在毛洼乡对小麦(地膜)花生一年三收带状轮作栽培技术及应用价值做了研究,1986年在试验的基础上搞了400亩带状轮作示范,经过两年的试验、示范,取得了较好的效果。 一、小麦花生一年三收带状轮作制模式。 小麦花生一年三收的模式为:采用4.6尺带田种植,当年秋后一半种4行小
In the past year, 230,000 mu of peanut and 130,000 acres of wheat (maize and corn) have been sown in our county. Because of the long-term land use, there is a phenomenon of planting a single species, that is, middle-class and fertile land is planted with more wheat (maize corn) In order to improve grain yield and land utilization, we conducted a survey on wheat (mulch) in Maowa Township from 1985 to 1986, Peanut three take a strip of round the crop for cultivation techniques and application values were studied in 1986 on the basis of the experiment to engage in 400 acres of ribbon wheel for demonstration, after two years of testing, demonstration, and achieved good results. First, a three-year wheat peanut take the ribbon mode of rotation. Wheat peanut three crops a year to receive the model: the use of 4.6-foot field planting, autumn half of that 4 small
