近年来,我们针对种植业上存在的主要问题,组织山区、丘陵和岗地平原的有关县市的土肥站,进行了冬季农业新技术的试验、示范,取得了较好的效益。现仅就其中的麦地压草技术简介如下。 麦地压草是在麦地实行秸秆直接还田的一项新农艺,它是继我省早稻草还晚稻田之后秸秆还田的又一新发展。这种方法较好地在大面积上解决肥料不足,特别是有机肥缺乏下的一项十分现实的技术。去年秋播,全省17个县市开展了麦地压草的试验示范,面积达60万亩。据今年夏收的32个基点验收结果,在原有氮磷肥的基础上,稻草全部翻压(亩含风干草250公斤)的每亩增麦40公斤;高留桩(含风干草125公斤)的每亩增15公斤;播后覆盖(含风干草150公斤)的 In recent years, we have tested and demonstrated new winter agricultural technologies in response to the major problems in planting industry by organizing earth stations in counties and cities in mountainous, hilly and hillside plains, and achieved good results. Now only one of the wheat pressure grass technology briefings are as follows. Corn straw is a new agronomism that straw directly returns to the field in the corn field. It is another new development of returning straw to the field after the early straw in the province and the late rice field. This method is better at large areas to solve the problem of insufficient fertilizers, especially the lack of organic manure under a very realistic technology. Last autumn broadcast, 17 counties and cities in the province launched a test demonstration of maize weeds, an area of ​​600000 acres. According to the results of the 32 basis points acceptance tests carried out this summer, 40 kilograms per mu of wheat was added on the basis of the original nitrogen and phosphorus fertilizers and all the straw was turned over (250 kg of hay of dry grass) Mu increase 15 kg; sowing coverage (including wind hay 150 kg)
