摘要
叶面喷施不同水平的多效唑(PP333)、稀土(XT)、高乐(GL)组合植物生长调节物质,调节锥栗Castanea henryi营养生长效应。结果表明:不同处理下枝条的粗度、长度、节数和节长具有一定程度的差异,叶片的蛋白质质量分数和叶绿素质量分数具有显著差异;对营养生长起主导作用的因子是叶面喷施PP333,经济而有效的生长调节处理应为PP3334.95 g.L-1+XT 2.64 mL.L-1+GL 1.00 g.L-1+比久(B9)2.00 g.L-1+硼砂(PS)2.00 g.L-1。
Excessive growth of Castanea henryi is a serious problem, which will result in poor harvest . Through spraying different plant growth regulators solutions on the leaves of Castanea henryi, the effect of the regulator growth on the vegetative growth was investigated. The results showed that the size, the length, the bud number and the burl length of the stem under different treatments were different in some degree. The differences of the protein and chlorophyll contents in the leaves were rather obvious. Paclobutrazol was the key factor and had the dominant function for the vegetative growth of Castanea henryi. The best economic and effective disposal was the water solution of Paclobutrasol 4.95 g· L^- 1 ＋ rare earth 2.64 mL· L^- 1 ＋ Crow more 1. 00 g· L^- 1 ＋ daminozide 2. 00 g· L^- 1 borax 2.00 g· L^- 1 for folia application. It could effectively inhibit the excessive growth of the new branches of Castanea henry/. [ Ch, 3 tab. 18 ref. ]
