少耕是尽可能减少耕作程序、降低生产成本、避免破坏土壤结构、提高劳动生产率的有效耕法。黑龙江省当前在生产上采用的少耕法主要包括:深松耕法、耙茬耕法、搅垅耕法和原垅卡种等。这些耕法与黑龙江省沿用多年的平翻耕法相比,都有不同程度的保持土壤水分、防止水土流失、降低生产成本和提高产量等效果。现简介如下。 Less tillage is an effective tillage that minimizes tillage procedures, reduces production costs, and avoids damaging the soil structure and increases labor productivity. The current low-tillage methods used in production in Heilongjiang Province mainly include deep-plowing, raking and tillage, agrarian farming, and primitive tillage. These tillage methods have many effects such as keeping soil moisture, preventing soil erosion, reducing production cost and increasing yield, compared with the flat tillage method used in Heilongjiang Province for many years. Now the introduction is as follows.
