| 摘 要： | 研究了西林2号和陕核1号核桃喷施硫酸钾对其果实钾素营养及种仁粗脂肪含量的影响.结果表明:喷施硫酸钾对青皮中钾和种仁粗脂肪最终含量影响不显著,但在油脂转化期,品种对其影响显著;在核桃果实生长期间,青皮中钾和种仁粗脂肪含量积累规律相似,且二者极显著正相关.钾肥效应主要是通过增产来提高单位面积的产油量;比较而言,西林2号更适合作为高油品种推广. |

| Abstract: | xilin 2 # and shanhe 1 # among walnut varieties were used in the experiment with sprays of 0. 3% K2SO4, lipids in the kernel and potassium in the shuck was investigated. The results showed that spraying 0. 3% K2SO4 had no significant effects on the final contents of lipids in the kernel and of potassium in the shuck, but the varieties level of indexes in the two walnuts were significantly different during the fruit oil transforming phase. At the growth stage of walnut fruit, the regularity of accumulation of potassium in the shucks and liquids in the kernel was similar and there exists very significant positive correlation between them. Effect of potassium fertilizer was mainly increasing walnut yield and yet enhanced oil yield in unit area; by comparison, xilin 2 # was fit for popularizing as a high oil walnut variety. |
