红壤结构很坏,保水保肥力弱,加上本地区气候干湿季节明显对农业生产的影响很大,特别是在干旱季节(7～10月)作物每因得不到正常水分的供应而停滞生长,凋萎而减产。在缺乏灌溉条件下,根据群众经验耕深破塥(犁底层)可以抗旱,但由于红壤表土浅薄,有机质营养元素均低,如果深翻似不能有效利用肥沃表土层,由于苏联T.C.马尔采夫耕作法松土原理的启示,采取了几种不同的耕作进行比较,以探求从耕作上战胜旱灾的方法。
The structure of red soils is very poor and water and fertility are weak. In addition, the wet and dry seasons in this area obviously have a great impact on agricultural production. Especially in the dry season (July-October), the crops are stagnant because of the supply of normal moisture Growth, withered and cut. In the absence of irrigation, according to the experience of the people, plowing the bottom of the plow can resist drought. However, due to the superficiality of the surface soil and the low nutrient content of the organic matter in the red soil, if the deep plowing fails to effectively utilize the fertile topsoil, Enlightenment from the law of loose soil, took several different farming to compare, in order to explore ways to overcome the drought from farming.
