    摘要:

    采用二次通用旋转组合设计,开展桉树幼林施用钙镁磷肥、尿素、复合肥、硼肥4种肥料组合定位施肥试验,结果表明,桉树幼林施用钙镁磷肥、尿素、复合肥和硼肥均有显著或极显著的促生效应,且钙镁磷肥与尿素、复合肥的交互效应不明显,而硼肥与钙镁磷肥、尿素或复合肥以及尿素与复合肥均存在交互效应;营养元素的重要性排序为N>P>K>B,N、P元素的单独施用只有在P2O5 52.5 g?株 -1 、N 46 g?株-1 以上时才具有明显 促生效应,而N、P、K肥配施能有效促进生长,同时施用硼肥只有在施用适量N、P、K肥料的前提下才有意义; 最优施肥组合为每株施钙镁磷肥500 g+尿素200 g+复合肥425 g+硼砂30 g(N 160 g,P2O5 143 g,K2O 68 g, CaO 200 g,MgO 60 g,B 4.5 g,有效养分总量635.5 g), N∶ P2O5 ∶ K2O∶ CaO∶ MgO∶ B=1.00∶ 0.89∶ 0.43∶ 1.25∶ 0.38∶ 0.03,以理论产量的70%作为目标产量的可能性,则采用本施肥配方2年生单株材积效应值可达0.027 8 m3 。

    Abstract:

    Using quadratic general rotation design approach,set up fertilizer combination fertilization experiment of cacium magnesium phosphate fertilizer,urea,compound fertilizer and boron fertilizer in young Eucalyptus plantation,the result showed that:application of calcium magnesium phosphate fertilizer,urea,compound fertilizer,and boron were significant- ly or very significant promoting effect,and the interaction effect of calcium magnesium phosphate fertilizer and urea,calci- um,magnesium phosphate fertilizer and compound fertilizer was not obvious.However,the interaction eccect were patency between boron fertilizer and calcium magnesium phosphate,compound fetilizer,urea or between urea and compound fertiliz- er;Nutrient elements in order of importance as N>P>K>B,N,P elements in a single application only P2O5 over 52.5 g ?tree -1 ,N more than 46 g?tree -1 obviously promoting effect,white the N,P,K fertilizrs could effective in promoting growth,white appplication of boron fertilizer was meaningful only in the N,P,K fertilizers under the premise of the right a- mount;The optimum fertilizer combination was each tree using 500 g calcium magnesium phosphate,200 g urea,425 g compound fertilizer and 30 g borax(N 160 g,P2O5 143 g,K2O 68 g,CaO 200 g,MgO 60 g,B 4.5 g,total amount of avaitable nutrient was 635.5 g),N∶ P2O5 ∶ K2O∶ CaO∶ MgO∶ B=1.00∶ 0.89∶ 0.43∶ 1.25∶ 0.38∶ 0.03.The theoretical yield 70% of the production possibilities as a target,the use of the fertilization formula.Stands wood volume up to 0.027 8 m3 in 2 years.
