施肥对降香黄檀营养生长和生殖生长的影响
Effects of Fertilization on the Vegetative and Reproductive Growth of Dalbergia odorifera T.Chen.
摘要
Abstract
The experiment was conducted to study the fertilization on vegetative and reproductive growth of Dalbergia odorifera,and then provide useful suggestions for plantation management.The effects of Nitrogen (N,185.6 g N per tree),Phosphorus(P,120 g P2O5 per tree),Potassium(K,120 g K2O per tree) as well as their mixtures(PK,120 g P2O5 mixed with 120 g K2O per tree;NPK,185.6 g N mixed with 120 g P2O5 and 120 g K2O per tree) on leaf growth,branch development,inflorescences set and biomass accumulation of a 8-year-old D.odorifera plantation were studied.There were significant differences on vegetative and reproductive growth of D.odorifera among these treatments (P ＜ 0.05).Nitrogen (N) treatment was helpful for vegetative growth of D.odorifera,and suitable for large-timber forest cultivation,because the ratio of vegetative branch,leaf number and leaflet width of vegetative branches were increased by 40.25％,21.75％ and 9.52％,and the inflorescence diameter and biomass were decreased by 12.75％ and 48.63％,respectively.While P and P mixed with K were more appropriated for breeding purpose,because the ratio of vegetative branch was decreased by 47.96％ and 46.84％,respectively.When N,P and K were mixed together(NPK),the vegetative and reproductive growth were both enhanced significantly (P ＜ 0.05),because the ratio of vegetative branch,length of vegetative branch,leaf number,leaflet length,leaflet width,branch biomass,inflorescence number and inflorescence biomass were increased by 26.04％,68.16％,32.98％,15.20％,11.40％,83.60％,54.20％ and 49.84％,respectively.Thus,the vegetative and reproductive growth of D.odorifera can be regulated though formula fertilization(biased to N or P and K).关键词
