摘要
为了了解目前丰产雷竹地土壤养分状况 ,作者在 1999年春天采集了临安市 5个乡、镇33个雷竹大户的竹林地土壤。分析结果表明 :雷竹地土壤养分差异较大 ,33个林地土壤有机质、全氮、水解氮、有效磷和速效钾含量的变异系数分别达到 34 .76%、4 1.18%、54.50 %、78.76%和78.34 %。林地土壤氮、磷、钾比例失调 ,主要表现在磷残留量过高 ,33块竹林地中有效磷含量超过10 0 mg·kg-1的林地占 57.58% ,超过 2 0 0 mg·kg-1的占 18.18%。针对目前生产上雷竹林地土壤养分的不合理状况 ,提出了测土施肥。
To understand the nutrient status of soil under high yield Phyllostacys Praecox f.Prevelnalis forest,a investigation was conducted by sampling and analysing 33 soil of sites which locate across 5 villages and towns in Linan in spring of 1999.The results indicate that soil nutrimental contents vary deeply in different sampling sites.The variation coefficients of organic matter,total nitrogen, hydrolyzable nitrogen,available phosphorous and rapid available potassium are respectively 34.76%,41.18%,54.50%,78.76% and 78.34%.The soil nutrients,N,P,K,are out of proportion.There is too much phosphorous depositing in soil,totally 57.58% sites are high to 100ppm,18.18% sites are more than 200ppm.To remedy soil nutrients imbalance,it is necessary to fertilize according to the analysing results of soil and the priciple of nutrients balance.
