摘要:
通过N,P,K 3因素3水平的正交施肥试验,分析了不同N,P,K肥配施对福建省沙县毛竹林新竹生长的影响。结果表明,一定施用量范围内的N,P,K肥组合在不同程度上影响着毛竹林新竹的生长,9个施肥处理与对照(未施肥)比较,各处理之间除新竹胸径差异不显著以外,新竹竹高、株数、产量均达差异显著或极显著水平,其中N3P1K3(尿素1 050 kg/hm2, 过磷酸钙900 kg/hm2, 硫酸钾300 kg/hm2)的新竹胸径生长达最大(10.8 cm),比对照增长14.9%;N3P3K2(尿素1 050 kg/hm2, 过磷酸钙1 350 kg/hm2, 硫酸钾150 kg/hm2)的新竹竹高达最大,比对照增长11.3%;选择施肥后新竹产量作为评价施肥效应的综合指标,极差分析认为,施用均衡且适当的N肥(尿素750 kg/hm2)、P肥(过磷酸钙900 kg/hm2)、K肥(硫酸钾150 kg/hm2),其新竹产量为25.8 t/hm2,比对照增长79.2%,能为新竹生长提供足够的养分。
Abstract:
An orthogonal trial of three-factor multiple fertilization designed in Shaxian, Fujian Province, dealt with effects of different prescription (N,P,K)on the growth of young Phyllostachys edulis. The result showed that all different prescriptions were favorable for the growth. The biggest diameter at breast height (BHD) was 10.8 cm (14.9% higher than that of CK) after treating with N3P1K3, and the highest new bamboo (11.3% higher than that of CK) was produced after treating with N3P3K2. There occurred significant difference (P<0.05) between different treatments for the young bamboo height, number and yield production but BHD. The optimal combination of fertilization was concluded as 750 kg/hm2 urea+900 kg/hm2 Ca(H2PO4)2·H2O, + 150 kg/hm2 K2SO4, with bamboo yield production of 25 800 kg/hm2, 79.2% higher than that of CK, illustrating balanced and sufficient nutrient supply for the growth.
