1987～1988年用几种植物激素与营养元素配套喷施,对提高元帅苹果座果率的影响进行了试验。结果表明激素混合物比单一施用效果显著,处理A(GA30ppm+BA50ppm+EF150ppm),B(BA20ppm+EF150ppm)和C(EF200ppm十尿素O.4％+硼砂0.4％)能使元帅苹果在自然座果率8％的基础上达到翻番,满足了盛果树生产负载要求。试验还表明在花期逆境下激素混合物对提高座果的效应更大。为此,建议花期降温或受冻频繁的地区,激素混合物可作为生产常规措施应用。
1987 ~ 1988 with several plant hormones and nutrients supporting spray, to improve the Marshal apple fruit rate was tested. The results showed that the hormone mixture was more effective than single application. The treatment of A (GA30ppm + BA50ppm + EF150ppm), B (BA20ppm + EF150ppm) and C (EF200ppm +0.4% + borax 0.4% 8% on the basis of doubled to meet the Shengguoshu production load requirements. The experiment also showed that the hormonal mixture had a greater effect on increasing fruit set during flowering adversity. For this reason, it is recommended that in regions where the flowering period is reduced or where frequent freezing occurs, the hormone mixture may be applied as a conventional measure of production.
