为解决我县红星苹果座果率低(5-10%)的问题,于1985—1988年进行了疏花试验。于花序分离期对每个花序疏除边花仅留中心花,以不疏花为对照,单株小区,重复三次。试验结果,疏除边花留中心花较不疏花提高座率6.5倍,产量提高2.4倍;而且,果台基部叶片明显大而厚。该项技术操作简单,可 In order to solve the problem of low fruit rate (5-10%) of Red Star apple in our county, a flower-thinning test was carried out in 1985-1988. In the inflorescence separation of each inflorescence sparse side flowers only leave the center of flowers, not thinning for the control, single plant, repeated three times. Test results, sparse edge flower center spend less flowers to improve seat rate of 6.5 times, yield increased by 2.4 times; Moreover, the fruit base is obviously large and thick leaves. The technology is simple to operate
