近几年来,以小麦、油菜为前茬的耕作制度改革,经受了低温、干旱和早期霜冻等自然灾害的考验,已在我省迅速推广开来。实践充分证明,以小麦、油菜为前茬的耕作制度改革,是我省发展粮油生产,实现一茬变两茬、粗粮变细粮,高产再高产的有效途径。 In recent years, the reform of the tillage system that used wheat and rapeseed as the previous crop has withstood the test of natural disasters such as low temperature, drought and early frost and has been rapidly promoted in our province. Practice has fully proved that using wheat and rapeseed as the cultivation system for the previous crop reform is an effective way for our province to develop grain and oil production, realize double cropping of stubble, thinning of coarse grains, and then high-yielding and high-yielding.
