对料慈竹叶养分分析结果表明：竹叶养分以N为主,元素排序为N＞K＞Ca＞Ms＞P＞Fe,总含量在509·kg-1左右;施化肥多少对竹叶N、P、K、Ca含量无显著影响,对Mg、Fe有显著影响;1年生叶中Mg与P、Ca、Fe有显著的负相关,P、Ca、Fe间为显著正相关;竹叶养分状况以1年生叶的含量同生长量间的相关性大,嫩竹叶则小,因此诊断用样品以1年生叶为佳;竹材产量与竹叶养分含量关系表现为随元素个数的增加,相关系数渐次增大,故而产量与养分间的相关性表现为多因子的综合效应;施少量肥可增加竹叶Mg而降低Fe,因此施肥是提高产量的有效措施,最佳施肥方案为,每年施“尿素、过磷酸钙、氯化钾”肥分别为“69、9.48、7848”kg／hm2。
The results showed that the nutrient content of bamboo was mainly N, and the order of elements was N> K> Ca> Ms> P> Fe, the total content was about 509 kg-1. , P, K, Ca content had no significant effect on Mg, Fe; 1-year-old leaves of Mg and P, Ca, Fe significant negative correlation between P, Ca, Fe was significantly positive; bamboo nutrient The results showed that the correlation between the content of one-year leaf and the amount of growth was large and that of the tender bamboo was small, so the sample for diagnosis was better for one-year leaf. The relationship between bamboo yield and nutrient content of bamboo showed as the number of elements increased, The correlation coefficient increased gradually, so the correlation between yield and nutrients showed a multi-factor effect; Shi Shi amount of fertilizer can increase the bamboo leaves Mg and reduce Fe, so fertilization is an effective measure to increase yield, the best fertilization program, the annual Shi “urea, superphosphate, potassium chloride” fertilizer were “69,9.48,7848” kg / hm2.
