我省大面积推广了“蓄水覆盖丰产沟”的耕作技术,使粮食作物普遍增产,这种耕作技术的改革对半干旱地区的农业有着重要的意义。我们把这种方法经改进后推广应用于果树上,叫做蓄水贮肥秸杆覆盖法。经过两年的试验和观察,取得了显著的效果。 A large area in our province popularized farming techniques of “covering water with abundant yield ditches” so as to increase grain crops generally. The reform of such farming techniques is of great significance to agriculture in semi-arid areas. We put this method after the promotion of the promotion applied to the fruit tree, called storage straw fertilizer cover law. After two years of experiment and observation, remarkable results have been achieved.
