摘  要:
通过田间小区试验,研究了不同施肥处理对撑绿竹地上部秆、枝、叶的氮磷钾养分含量的变化规律,旨在揭示撑绿竹的需肥规律,为其规范化种植提供依据。结果表明:不同施肥处理氮磷钾的年吸收量、各器官的养分年吸收量以及地上部各器官的养分吸收总量均是随着施肥量的增加,呈现先增加后减少的规律,在处理4时达到最大。

摘  要:
The effects of different fertilizer application on stem,branches,leaves NPK nutrient content variation of Bambusa pervariabilis×dendrocalamopsis daii,it's aimed to reveal the requirement for fertilizer law bamboo pole,its provided the basis for standardized cultivation.The results showed that different fertilization treatments NPK uptake,the various organs of nutrient uptake and aboveground organs of the total nutrient uptake with the increase of fertilizer amount s,its increases at early stage and decreases at later stage,the masimun uptake amounts was treatment 4.
