在试验推广深松少耕法的过程中,从八种耕作措施中筛选出用小铧杆尺深松犁,进行浅翻间隔深松,浅翻7—8厘米,间隔35厘米,深松20—35厘米,创造的虚实并存的耕层(虚实比8∶4),由于表土位置不变,水、肥、气、热协调,增产效果稳定,种小麦、大豆平均增产分别为21.6%和15.5%;而且还有节省油料、降低成本,不用大量增添新的耕作机具的优点,并具有明显的抗旱、抗涝、防止土壤风蚀、水蚀的结果。
In the process of testing and popularizing the method of deepening and reducing tillage, we selected from the eight tillage measures the deep plow with the small piece bar-rod, the deep plow with shallow plowing, the shallow plow with 7-8 cm, the interval 35 cm and the deep pine 20 -35 cm, creating the tillage of the coexistence of the actual situation and the actual situation (the ratio of the real and the real is 8: 4). Due to the unchanged topsoil, water, fertilizer, gas and heat, the yield increase is stable. The average yield of wheat and soybean is 21.6% and 15.5 %; But also save fuel, reduce costs, do not add a lot of the advantages of new farming machinery, and has obvious drought, waterlogging, prevent soil erosion, water erosion results.
