惠满丰对板栗生长、光合特性及产量的影响

8年生板栗树于春季萌芽期和萌芽后20d，两次用不同浓度惠满丰采取枝叶喷施、灌根、涂干等不同方法处理后，叶片的叶绿素含量、光合速率、可溶性糖和淀粉含量提高；树体生长健壮，株高增长率、干径增粗率上升，果技增长增粗，叶面积增大，叶鲜重、干重增加；果实空苞率下降．总苞重、粒重、出实率增加，产量提高。以2500mg·L－1喷施处理效果最好，增产率达18.1％。

The Influnce of Komix on Growth Photodynthesis Character and Yield of Chestnut

The chestnut trees of 8 years were treated by spraying branches and leaves,irrigating roots, and smearing stem with different concentration of komixtwice in budding and 20 days after n budding in spring. The results showed that chlorophyll content of the leaf,photosynthetic rate, and the content of soluble glycogen and amylum incteased; the trees grew strongly, bearing shoots got longer and thicker, the increasement percentage of plant height and stem thichness,the area of leaf, fresh weoght and dry weight of leaf all improved;the carvity percentage of frult decreased, periclinium weight, seed weight, fertile rate and yield enhanced. In comparison, the effect of treatment spraying branches with 2500mg/lkomix was most remarkable,which rate of increasing in yield amounted to 18.
