隔年松翻,就是在一块耕地上,第一年进行秋松土,第二年秋翻地,第三年进行大垄苗间松土的耕作方法。它既可打破犁底层,又具备翻地的好处。一般松土和机翻地间隔一年为宜。如果是风沙大的地块,秋天原垄不动,春天顶浆耙压,出苗后进行苗间松土,其产量与隔年松翻法及连年翻地法基本相同。但节省了翻地和秋松土作业的费用。由于秋天原垄不动,好土不易被风吹走,对保土保肥有利。风沙地区,进行耙压苗松土耕作法,比隔年松翻法和连年翻地法效果还好。
Loose the next year, that is, in arable land, the first year of autumn soil, autumn the second year, the third year of cultivation of large ridge seedlings loose soil farming methods. It can break the plow floor, but also have the benefits of turning the ground. General loose soil and machine turning interval of one year is appropriate. If it is large sandstorms, the original ridge does not move in autumn, spring jacking rake pressure, seedling after emergence of loose soil, the yield and the second year of loose law and successive years of turning law is basically the same. But saves the cost of turning the earth and autumn soil operations. As the original ridge does not move in autumn, good soil is not easy to be blown away and it is good for the soil conservation. Aeolian sand area, rake seedlings loose soil tillage method, than the second year of loosening method and successive years turn the law effect is better.
