施用硼肥对白糖杨梅生长发育的影响

白糖杨梅是一种深受人们喜爱的珍稀杨梅品种,但其产量很低,硼素营养缺乏是一个重要原因。本文采用田间试验的方法研究硼素营养对白糖杨梅生长发育的影响。结果发现,硼素对白糖杨梅的生长发育有显著的影响。叶片硼、全氮、全磷及全钾的含量均随硼肥用量的增加而增加,果实的坐果率、粗蛋白、粗纤维、粗灰分、全氮、全磷及全钾含量也随硼肥用量的增加而增加。在本试验条件下的浓度为4.00g/L的硼砂处理较为适宜。

Effects of Borax on the development of white bayberry

In order to study the reasons of low yields of white bayberry,six treatments,0.00%,0.05%,0.10%,0.20%,0.40% and 0.80% borax in the solution,respectively,were considered.There were great effects of borax fertilizer on white bayberry.The concentrations of boron,total nitrogen,total phosphorus and total potassium in leaves increased with the increasing of borax fertilizer,and the fruit set ratio,crude protein,crude fiber,crude ash,total nitrogen,total phosphorus and total potassium of fruit had similar trend.This indicats that the suitable concentration of borax is 0.40%.
