在我国小麦主产区,旋耕整地是普遍采用的耕作方式,耕层浅已成为制约小麦产量进一步提高的主要因素之一。试验研究证明,深耕25 cm与旋耕15 cm相比平均每亩增产40.3 kg,增产率7.8%,增产效果显著。
Rotary tillage and land preparation are commonly used tillage methods in the main wheat producing areas of our country. Shallow tillage has become one of the main factors restricting the further increase of wheat yield. Experimental studies have shown that the average yield per mu of 40 cm deep plowing 25 cm compared with 15 cm rotary cultivating is 7.8% increase yield, the yield increase effect is remarkable.
