| 摘 要： | 通过花生(Arachis hypogaea L.)新品种信花425共6个种植密度处理(10 000、11 000、12 000、13 000、14 000、15 000穴/667 m~2,每穴2粒)试验,采用随机区组设计,3次重复,分小区单收刨、单摘果,晒干后称出小区实际产量,分析不同种植密度对信花425产量的影响。结果表明,夏直播花生种植密度一般在10 000~15 000穴/667 m~2,随着密度的增加,株高增加,分枝数和有效分枝数减少;信花425的种植密度为12 000穴/667 m~2时,能较好地协调其夏直播各产量构成因素之间的关系,能取得最高产量。

| Abstract: | New peanut variety Xinhua 425 was planted under 6 planting densities of 10000,11000,12000,13000,14000 and 15000 hills/667 m2 with 2 seeds per hill to study the effect of planting density on peanut yield. Result showed that with the increase of density in summer peanut, the plant height increased, and the number of branches and the number of effec-tive branches decreased. The highest yield was achieved under the density of 12000 hills/667 m2. |
