摘花摘果对牡丹皮产量的影响

Effect of flower-picking or fruit-picking on the yield of Mudanpi

目的:比较摘花或摘果对不同类别牡丹皮产量的影响。方法:按花蕾数量不同将试验地各株牡丹分为单花植株类(每株仅有1个花蕾)、双花植株类(每株仅有2个花蕾)和多花植株类(每株花蕾3个及以上),各类再分别随机分为3个组,分别作对照(不摘花果)、摘花蕾、摘幼果处理。于当年10月中旬采挖牡丹根,记录其根径大小并进行统计学处理和比较。结果:经摘花或摘果处理后,单花植株可增产约10%-12%;双花植株产量可增产约7%-10%;多花植株可增产约3%-6%。从整体上看,摘花摘果大约可以将牡丹皮产量提高6%-7%。结论:摘花摘果对开花较少的牡丹植株增产影响较大,对开花较多的牡丹植株增产影响较小。

Objective:To compare the effects of flower-picking or fruit-picking on the yield of different kinds of Mudanpi.Method:The peonies for the experiments were divided into three categories according to the number of buds,including singleflower plant(only one bud per plant),double-flower plant(2 buds per plant)and multiple-flower plant(3 or more buds per plant),and each category was then divided randomly into three groups,including control(not picking flowers or picking fruits),budpicking,and young fruit-picking groups.The peony roots were dug in the middle of October of the year,and the root diameter was recorded for subsequent statistic and comparison.Result:After the flower-picking or fruit-picking treatment,the yield of single-flower plants increased by about 10%-12%,the yield of double-flower plants increased by about 7%-10%,and the yield of multiple-flower plants increased by about 3%-6%.Overall,picking flowers or picking fruits could increase the yield of Mudanpi by about 6-7%.Conclusion:Picking flowers or picking fruits has great effect on the increase in yield of the peonies with few flowers,but minor effect on that of the peonies with multiple flowers.
