目前,在我省农业生产上,连年翻地还是隔年翻地,争论较大.因为它涉及到今后在机械化耕作制度变革中,是多耕还是少耕、耗油量能否减少、作业成本能否降低这些急待解决的问题,为此我们在河淤土上进行了几种作物的轮翻试验.试验选用大豆、麦复豆、高粱、玉米等4种茬口的土地,于1978年秋开始不翻地,翌年春耙10厘米深,对照是1978年秋翻18厘米深.1979年播种玉米、高粱、大豆、小麦四种作物.产量结果表明,翻地播种与耙地播种的作物产量一般无显著差异,而耙地播种的大豆比翻地播种的还增产9%.说明河淤土的土壤类型,不连年翻地,也不影响作物产量.
At present, the issue of agricultural production in our province is still controversial because it involves more farming or less farming in the mechanized farming system in the future, and whether the fuel consumption can be reduced or not, and the cost of homework Whether or not to reduce these urgent problems to be solved, for which we carried out several crop rotation test on the river silt.Experiments using soybeans, wheat, beans, sorghum, corn and other stubble land, starting in the fall of 1978 Turn the ground, the next spring rake 10 cm deep, the control turned 18 autumn 1978 autumn, sowing corn, sorghum, soybeans, wheat four crops in 1979. Yield results show that the turn of seeding and harrow crop seeding generally no significant Difference, while the sown crop harrowed rake increased by 9% than the sown land, indicating that the soil type of river silt did not affect the crop yield without annual turning.
