| 摘 要： | 分析了分别喷施生长调节剂、稀土、二者混合喷施及喷清水4种处理对锥栗高、中、低产三种类型8年生林分产量的影响。结果表明:不同处理对同种林分增产效果表现为,喷施400mg·kg-1的稀土最好,其次是5g·kg-1的TDS,混合喷施(400mg·kg-1稀土 5g·kg-1TDS)不如各自单独施用,清水对照处理的产量最低。同一处理类型对不同产量类型林分的增产效果随着高、中、低产量类型的顺序而增加。产量增加的生理基础是提高了树体叶绿素含量,增强了光合速率。

| Abstract: | The effects of plant growth substances,rare-earth,the mixture of plant growth substances and rare-earth,and water on the yields of 8-year-old Castanea henryi plantations with high,middle and low yields were analyzed.The results indicated that the yield of Castanea henryi plantation treated with 400 mg·kg-1 rare-earth elements increased the most,followed by 5 g·kg-1 TDS and the mixture (400 mg·kg-1 rare-earth elements+5 g·kg-1 TDS).The effect of water was the poorest.The effect of treatment was positively correlated with the type of plantation.The higher the yield of plantation,the more the yield increased.The physiological basis of yield increase was the increases of the content of chlorophyll and the photosynthetic rate by these treatments. |
