为了增加花生饱荚率,提高单位面积产量,从而为大面积提高花生单产开辟新的途径。七三年我县在花生重点产区,对花生施用石膏进行多点试验。选择不同土质、茬口、施肥管理水的田平块,设置七个试验,十四个处理,每处理面积为0.1-0.5亩。试验田的土壤呈比较强的石灰反应,PH值8左右,水溶性钙(Ca)含量为0.044—0.077％,含NO.052—0.06％,有机质为0.519—0.790％, In order to increase the rate of peanut pod and increase yield per unit area, a new way to increase peanut yield for large area is opened up. In seven or three years my county key peanut producing areas, the use of gypsum peanut for more tests. Select different soil, stubble, fertilizer management of water Tianping block, set seven trials, fourteen treatment, each treatment area of ​​0.1-0.5 acres. The soil in the experimental field showed relatively strong lime reaction with about pH 8, the content of water-soluble calcium (Ca) was 0.044-0.077%, the content of NO was 0.052-0.06%, the content of organic matter was 0.519-0.790%
