摘要
在云南省陇川县4个立地条件相似的试验点分别设置2个667 m2的试验样地进行麻竹竹腔施肥试验,每年5月、8月各用注射器注入150 ml 5%复合营养液于竹腔内。结果表明,与传统方法相比,竹腔施肥方式能提高竹笋产量,降低肥料用量及用工量,并能提早约1周时间出笋,有较好的经济效益,并能减少肥料流失造成的污染。
In this trail,two sample plots of 667 m2 have been set for cavity injection fertilization on Dendrocalamus latiflorus in four similar site condition fields in Longchuan County of Yunnan Province. The recombination nutrient solution was injected in cavity of Dendrocalamus latiflorus in May and August every year,the results showed that the method of cavity injection fertilization on Dendrocalamus latiflorus had advantages compared with control e. g. increasing yield,reducing fertilizer rate and amount of labor,favorable economic benefit,shorten budding time,decreasing pollution made by fertilizer run away and so on.
