低丘陵红壤在金华地区分布面积很大,一般土层均较深厚,是本地区主要的土壤资源.目前这个地区除沟谷水田外,大部旱作地均以种植甘薯、小麦、花生等作物为主,其中以甘薯-小麦二熟制较为普遍;有不少面积则只种一季甘薯.这些旱地均无灌溉设施,秋旱威胁很严重,同时耕作粗放,肥力不易提高,致使作物产量很不稳定,甚至不保收.为了发掘土壤潜力,提高单位面积产量,必须合理利用土地,发展多种经营.本区“地改田”就是在这种前提下涌现出来的新措施,也是红土丘陵地区改变耕作制度的重要方向.
Hilly red soil in Jinhua area distribution is very large, the general soil layers are deep, is the main soil resources in the region.In this area except valleys paddy fields, most of the dry land are to grow sweet potato, wheat, peanut and other crops are Lord, of which the sweet potato - second generation of wheat is more common; there are many areas, only one season of sweet potato. These drylands have no irrigation facilities, autumn drought threat is very serious, while extensive farming, fertility is not easy to increase, resulting in very unstable crop yield In order to explore the potential of the soil and increase the output per unit area, it is necessary to make rational use of the land and develop diversified operations. The “land reform” in this area is a new measure that emerged under this premise, The important direction of the system.
