采用三因素五水平回归通用旋转试验设计，研究了花期喷施赤霉素、稀土、硼酸对核桃座果率的影响。结果表明，核桃大树在雌花盛期喷施赤霉素、稀土和硼酸能有效地提高座果率，三者作用程度顺序为赤霉素＞稀土＞硼酸。通过回归方程求得最佳浓度配方为：赤霉素５４×１０－６＋稀土４７５×１０－６＋硼酸１２７０×１０－６。此配方可使核桃座果率提高１１％～２０％
The three-factor five-level regression general rotation test design was used to study the effect of spraying gibberellin, rare earth and boric acid on the percentage of walnut fruit. The results showed that ginkgo, rare earth and boric acid could effectively increase the fruit setting rate when the walnut tree was sprayed with female flowers. The order of the effect of these three treatments was gibberellin> rare earth> boric acid. Regression equation obtained by the optimal concentration formula: gibberellin 54 × 10-6 + rare earth 475 × 10-6 + boric acid 1270 × 10-6. This formula can increase the percentage of walnut fruit set by 11% ~ 20%
