毛竹林科学施肥能在施肥数量同样的情况下增加产量,提高质量(笋嫩,可食部分多),节省成本,提高经济效益。近年,浙江省宁波市江北区农林局与轻工部、浙江林学院合作,在慈城镇五星村进行毛竹林氮、磷、钾不同肥料配比试验发现,氮肥的增产效果最显著,磷、钾肥效与土壤的氮素水平有关。在氮素水平较高的情况下,磷肥效果较好。而当氮素缺乏时则施钾肥更能见效。氮、磷、钾三要素最好的配比为4:3:1。氮肥主要通过对竹笋个体发育的促进作用来增加产量;磷肥是促进笋芽的分化来增加发
Phyllostachys pubescens science fertilization in the same amount of fertilizer to increase production and improve quality (shoots tender, edible part of more), save costs and improve economic efficiency. In recent years, Jiangbei District, Ningbo City, Zhejiang Province Agriculture and Forestry Bureau and the Ministry of Light Industry, Zhejiang Forestry College cooperation, Cicheng Town, Wuxing village of nitrogen, phosphorus and potassium fertilizers ratio test found that nitrogen fertilizer yield the most significant effect of phosphorus and potassium Effective with the soil nitrogen levels. In the case of higher nitrogen levels, phosphate fertilizer better. When nitrogen deficiency, potassium fertilizer is more effective. Nitrogen, phosphorus and potassium three elements of the best ratio of 4: 3: 1. Nitrogen mainly through the promotion of individual development of bamboo shoots to increase production; phosphate is to promote the differentiation of shoots to increase hair
