集约经营毛竹林平衡施肥效应研究

Research on the Effect of Balanced Fertilization in Intensively Bred Phyllostachys heterocycls cv.pubescens Plantations

对南方毛竹林采取平衡施肥等集约培育措施的结果表明:平衡施肥能显著提高毛竹的胸径和竹笋的营养品质,对其纯收入分析表明,N2P1K2是经济效益最高的施肥配比.平衡施肥不仅能减少肥料浪费和环境污染,还能显著增加毛竹林经营的经济效益及产值.

Phyllostachys heterocycls cv. pubescens forest is an important forest resource in south China. The result of balanced fertilization in the intensively bred Phyllostachys heterocycls cv. pubescens plantations showed that the balanced fertilization could significantly increase the DBH of the plants, improve the quality of bamboo shoot and consequently increase the economic incomes. It was indicated by analyses of net income of the intensively bred bamboo plantation that N2P1 K2 was the best fertilizer combination, which could yield the greatest economic benefits. It was demonstrated that the balanced fertilization could not only avoid environmental pollution, save fertilizers but also increase the productivity of Phyllostachys heterocycls cv. pubescens plantation and the economic benefits of the cultivation. So the balanced fertilization was one of the approaches to ensure economic and ecological benefits of intensively bred Phyllostachys heterocycls cv. pubescens plantation in south China.
