【摘要】 对沿海沙地麻竹进行施肥试验,结果表明:麻竹叶片N、P、K含量在不同发笋期有明显差异,但总体上均以末期的含量最低.不同发笋期各因素对叶片营养元素含量的影响不同,但均以施肥总量和N、P、K比例占主导因子,而施肥方法对叶片营养元素含量的影响相对较小.在不同发笋期最佳N、P、K比例均为2∶1∶1,但在初期和末期最佳施肥总量为720 kg.hm-2,施肥方法为浇施;在盛期最佳施肥总量为360 kg.hm-2,施肥方法为丛中穴施;在末期施肥方法以丛中穴施好.更多还原

【Abstract】 Through the fertilization experiment in Dendrocalamus latiflorus on the seashore dene,although the results showed that the contents of N,P and K had significant difference during growing bamboo shoots,the content was the lowest at the last stage in common.Each factor had different effect on the nutrition of leaves in different growth periods,but in large,the optimum factors were the total fertilizer and the proportion of N,P,K,and the method of fertilizer application had relatively smaller effect.The optimum proportion of N,P,K was 2∶1∶1 during different periods,but at the first and the last stages the optimum amounts were both 720 kg·hm-2,and the method of fertilization was pouring.In prosperous stage,the optimum amount was 360 kg·hm-2.Its method of fertilization was digging in the clumps;and so was it at the last stage.更多还原
