合理密植是花生增产的重要措施。我区栽培的花生,从植株分枝的生长姿态来分,有丛生和蔓生两大类型,以丛生花生栽培面积较广。我组一九七二年和一九七四年,进行丛生型花生不同密植程度的增产效果研究,并观察其个体和群体的经济性状,以及与结荚密切相关的分枝情况,现将结果总结如下: Reasonable close planting is an important measure to increase peanut production. The peanuts cultivated in our district are divided into two types according to the growth orientation of the plant branches. There are two types of clusters of peanuts and sprawls, and a broad area of ​​peanut cultivation. In our study in 1972 and 1974, we studied the yield-increasing effects of cluster peanut in different density and density, and observed the economic traits of individuals and groups, and the branches closely related to pod, now the results Summarized as follows:
