汉江及其支流两岸有大面积的黄泥巴土,因其透性不良,水难下渗,水土流失严重,给农业生产带来了很大困难。伹其土层厚,储水性能好,只要选出适宜其上生长的经济树种和作物,即可发挥其增产潜力。为此,1976—1983年我们在巴山北坡的黄泥土上,采用林粮间作,油、果树混植等方法进行了研究。试验证明,以梨树和豆类为主进行林粮间作,既可获得较高的经济效益,又可改善农业生产条件,同时改顺坡耕作法为水平带耕作法,是合理利用黄泥巴荒山坡的正确途径。
Because of its poor permeability, impervious infiltration and serious soil erosion, the Hanjiang River and its tributaries have a great deal of difficulties in agricultural production.伹 its thick soil, water storage performance, as long as the election of its suitable growth of economic species and crops, you can play its production potential. Therefore, from 1976 to 1983, we studied on the yellow mud soil of the north slope of Bashan by means of forest-grain intercropping, oil and fruit tree planting. Experiments show that the intercropping of forest and grain with pears and legumes can not only achieve higher economic benefits but also improve the conditions of agricultural production. In the meantime, The right way to the hillside.
