对杭州市桐庐县茶园、果园和桑园土壤肥力的调查表明,该县园地土壤酸化明显、土壤有机质和全氮偏低、土壤有效钾不足;土壤有效磷高低相差较大,茶园、果园土壤磷素缺乏明显,桑园土壤有效磷平均较丰富,但仍有一定面积的土壤存在磷素不足。建议重视园地土壤酸化的防治,增加有机肥料的投入,增强配方施肥的推广力度。
The investigation on soil fertility of tea plantations, orchards and mulberry fields in Tonglu County of Hangzhou showed that the soils in the garden of this county were obviously acidified, the soil organic matter and total nitrogen were low, and the available potassium in soil was not enough. There was a big difference between the soil available and available phosphorus, Vegetarian lack of obvious, mulberry soil average available phosphorus is rich, but there is still a certain area of soil phosphorus deficiency. It is suggested to pay attention to the prevention and control of soil acidification in the garden, increase the input of organic fertilizer and enhance the promotion of formula fertilization.
