摘    要:试验结果表明,磷对板栗(Castanea mollissima Blume)雌花的形成数量有重要影响,结果母枝含磷量与母枝抽生结果枝数量和着生雌花数量呈显著正相关。板栗结果母枝含磷量比雄花母枝和营养枝分别高5.19%和5.27%。树体磷素含量水平与板栗雌、雄花枝比例和结果枝结栗苞数量也存在密切的相关性。在不同施磷水平下,结果枝粗度与果枝结栗苞数均具有显著的回归关系,但b值差异大。本研究结果在鄂东大别山区进行了大面积施磷肥示范,生产实践证明,施磷肥对板栗具有一致的增产效益。

关 键 词:板栗    结果母枝  雌花  雄花

Abstract:This study reveals some important correlations between phosphorus and pistillates and fruiting character. It shows that P content of fruit branch is significantly positive correlation to amount of fruit bearing shoots and pistillates per fruit branch. The correlation coefficients are. r = 0.8286 and r = 0.9276 respectively. P content of fruit branch is 5.19% and 5.27% higher than that of staminate branch and vegetative shoots respectively. P content level in chestnut tree is closedly to the rate of pistillate shoots/staminate shoots, and bur numbers per fruit bearing shoot. With the different phosphorus treatment levels, significant regression equations have been established between diameter of fruit bearing shoot and bur numbers per fruit bearing shoot. However regression coefficients are greatly variation. Mutiple regression analysis shows that regression for P content of fruit bearing shoot ( X1 ) , dia-meter of fruit bearing shoot ( X2 ) and bur numbers per fruit bearing shoot ( Y ), results Y = -3.90 24X1 X2. Partial regession significance test proves only b1 reached significant level, which indicates that the relation between diameter of fruit bearing shoot and bur numbers appears a appearance of fruiting character but the P content of fruit bearing shoot acted important role in bur numbers per fruit bearing shoot. The study has also demonstrated that P fertilizer application in sandy P defficient soils increased chestnut yields efficiently.
Keywords:Phosphorus  Chestnuts  Fruit bearing shoots  Pistillate flower  Staminate flower
