茶杆竹林分施肥水平的研究

Research on Fertilization Dosage in Bamboo Stand of Paeudosasa Amabilis

报道茶杆竹施用碳酸氢铵以 6 0 0 kg/ hm2 ,另加过磷酸钙 12 0 kg/ hm2为最适宜水平 ,产笋量可达 75 0 0 kg/ hm2 左右 ,继续增加其施肥量 ,产笋量增加不明显 ,经济上也不合算。

The experimental results idicate that the optimum dosage of fertilizer for bamboo plantation of Paeudosasa Amabilis is about 600kg/hm 2 of ammonium bicarboate and 120kg/hm 2 of calcium super-phosphate. In this case,the output of bamboo shoots can reach up to 7 500kg/m 2.But the output of bamboo shoots increase slightly when fetilizer is more than this quantity and it becomes uneconomical as well.
