| 摘 要： | 1983—1985年在肖县苗山园艺场成年白羽品种葡萄上设株施250、500、750g氯化钾肥料作试验。3年结果表明,钾肥在施后第2年能增加产量,提高含糖量,增加新梢结果系数,但不显著;其主要作用是增强抗病性,在试验范围内病穗率随施钾量增多而减少;株施250g钾肥其有效期不超过两年;在碱地上施用氯化钾为避免Cl~-的不良影响,每株一次施量不应超过250g(51.5kg/亩)。

THE EFFECTS OF POTASSIUM CHLORIDE ON GRAPEVINE |
| |
| Abstract: | Theme effect of KC1 on grapevine is its anti disease quality which increased from application rate of 250-750g/vine. Two years after application a slightly increaing yield and fruit coefficient was shown, but not significant. The highest application rate of KCI applied to vineyard soil with an existing salinity condition should not be more than 51.5kg/mou, otherwise the yield and sugar content will decrease. The lower application rate of 250g/vine KC1 will sustain effectiveness no more than two years. |
