梁平白夹竹低改复壮技术研究及其经济效益分析

Research on Healthy Technique of Liangping Pyhllostachys nidularia Munro and the Analysis of Its Economic Efficiency

[目的]揭示各技术措施对提高白夹竹产量和质量的关系。[方法]设施肥、虫害防治、垦复、施肥+虫害防治、施肥+垦复、虫害防治+垦复、施肥+虫害防治+垦复7个处理,以不处理为对照,比较各措施对梁平竹山镇白夹竹笋产量的影响。[结果]通过施肥、虫害防治及垦复等低改复壮措施可以不同程度地增加新竹数量,但对新竹的平均胸径没有明显影响;与施肥、虫害防治相比,垦复的效果相对较差;虽然白夹竹新竹的产量随着低改复壮措施投入的增加而提高,但其收益与投入不成正比。从经济效益角度来讲,施肥+虫害防治处理对白夹竹笋产量的效果最优。[结论]白夹竹新竹的收益与低改复壮措施投入不成正比,在一定程度上影响了白夹竹产区林农发展白夹竹的积极性。

[Objective]The relationship between the improvement of technical measure and Liangping Pyhllostachys nidularia Munro yield and quality was explored. [ Method ] The effect of 7 treatments ： fertilization, pest-controlling, reclamation, fertilization ＋ pest-controlling, fertilization ＋ reclamation,pest-controlling ＋ reclamation and fertilization ＋ pest-controlling ＋ reclamation, and non-treatment as CK, on its bamboo shoot yield was compared. [ Results ] The technical measure such as fertilization, pest-controlling and reclamation for healthy bamboo growth could increase the number of its fresh shoot at the different degrees, but did not significantly affect the average diameter of shoot;and compared with the technical measure：fertilization and pest-controlling, the effect of reclamation on the number of fresh bamboo shoot was relatively poor. Although the yield of fresh bamboo shoot was improved though the application of these measures the ratio of the output to investment was not in proportion. From the viewpoint of economics, the best effect on the efficiency of Liangping Pyhllostachys nidularia Munro was from the combining measure of fertiliza- tion ＋ pest-controlling. [ Conclusion ] The .ratio of the income to technical application in Liangpiug Pyhllostachys nidularia Munro production was unbalanced.which affected the activity of forest farmer in the develooment of the industry to a certain extent.
