| 摘 要： | 2000年特旱年,燕沟流域通过推广抗旱保苗、调整作物种植结构、品种改良、增施肥料、大垄沟种植等技术措施,增产稳产效果显著,在全年降水量减少36.1%的情况下,粮食单产仍稳中有升,人均产粮达到了525.1kg。这对于黄土高原中部丘陵区坡改梯后保障食物安全生产、加快退耕还林还草步伐都具有一定的现实意义。

| Abstract: | The significant effects on stabilizing or raising grain output were obtained by extending the techniques of keeping crop seedling against drought, adjusting planting frame, using excellent varieties, applying fertilizer, and using the ridge-furrow planting method. Although the rainfall decreased by 36.1 percent compared with the general annual rainfall in the extremely dry year of 2000 in Yangou watershed, which made the grain output approached to 525.1 kg per capita. These alternatives can play the significant roles in insuring the grain security after shifting the slope land to terrace, and accelerating the process of conversion of certain cropland to forestry land and grassland in the hill and gully region in the middle of loess plateau. |
