摘  要:
对毛竹笋材两用林的配方施肥试验结果表明 ,施肥区的笋材产量与不施肥区相比有明显增加。施用 4种肥料 3a累计平均净增产鲜竹材 6 6 0 3 3kg/hm2 、鲜竹笋 5 44kg/hm2 。每公斤肥料 (按有效成分N ,P ,K计算 )年均净增产竹材 7 7kg、鲜笋 0 6 4kg。最佳施肥配方为A2 B1C2 D3 ,即每公顷施菜子饼 112 5kg ,N肥 15 0kg ,P肥 5 6 3kg,K肥75kg。其影响次序为A >C >D >B。使用这个配方竹林生产力最高 ,其中年均产竹材 2 1 96t/hm2 、竹笋 1 6 5t/hm2 ,收入 1 0 74万元 /hm2 。

摘  要:
By coordinate fertilization to culm and shoot producing bamboo stands,it was showed that the yield of bamboo increased significantly in the fertilized filed compared with non fertilized filed.The fresh bamboo timber increased 6 603 3 kg/hm 2,the fresh bamboo shoots 544 kg/hm 2 in 3 years in the test fields to apply four different fertilizers to.The test results also showed that 7 7 kg culm and 0 64 kg fresh bamboo shoots could be increased by applying 1 kg fertilizer(counted by N,P and K).The best fertilizer combinations were A 2,B 1,C 2,D 3(i.e.rape cake 1 125 kg,available urea 150 kg,calcium 56 3 kg,KCl 75 kg per hm 2).The order of effects were A>C>D>B.The optimal fertilizer combination of A could increased 21 96 t/hm 2 of culm,1 65 t/hm 2 of fresh bamboo shoots,and hence 1 074 yuan RMB/hm 2 of economic income.
