不同施肥方式对毛竹冬笋产量和品质的影响

Effect of Different Treatment of Fertilization on Yield and Quality of Phyllostachys heterocycla cv. pubescens Winter Shoot

2015年在浙江省台州市黄岩区选取了6个毛竹林样地,采取6种不同的施肥方式,研究其对毛竹冬笋产量和品质的影响。结果表明,竹腔施肥比氮、磷、钾配比施肥对冬笋增产效果更明显,每公顷提升21%;竹腔施肥和氮、磷、钾配比施肥相结合的方式比单一竹腔施肥增产效果更加显著,每公顷提升近60%。9月份竹腔施肥比4月份竹腔施肥更有利于冬笋品质的保障;4月施氮、磷、钾配比施肥,9月竹腔施肥最有利于提高冬笋品质。冬笋产量与品质没有显著相关。

Sample plots were selected at Phyllostachys heterocycla cv.pubescens forest in Huangyan,Zhejiang province in2015.Experiments were implemented on different treatment of fertilization on yield and quality of winter shoot.The results showed that cavity fertilization had better effect on yield of winter shoot(20%more)than directive one.Cavity and directive fertilization had even better effect on winter shoot yield,60%more than single cavity fertilization.Cavity fertilization in September had better result on shoot quality than that in April.Directive fertilization in April and cavity fertilization in September had the best effect shoot quality.The result demonstrated that winter shoot yield had no evident relation with quality.
