影响甜柿坐果率因素试验研究初报

Preliminary Study on Influence for Trial of Fruit-bearing Rate Factor of Sweet Persimmon

为解决甜柿坐果率低的问题,采取了人工授粉、花期喷施赤霉素和主干环剥等技术措施。结果表明:人工授粉、花期喷施赤霉素和主干环剥与对照比较分别高24.28%,17.15%,13.87%,均能显著提高甜柿的坐果率。虽然花期喷施赤霉素和主干环剥的平均单果重显著小于对照,但甜柿单位面积产量与对照相比仍有显著提高。

In order to solve problem of low fruit bearing of the sweet persimmon, we've adopted techniques of artificial pollination, GA3 spray in blooming period and ring peeling on main trunk etc. The result shows that these techniques used are higher by 24.28%、17.15% and 13.87% comparing with contrast trial which can improve fruit-bearing rate of the sweet persimmon remarkably. Although average single fruit weight of the techniques used with GA3 spray in blooming period and ring-peeling on the main trunk are smaller than the contrast trial evidently, unit area output of the sweet persimmon is much higher than the contrast trial.
