土壤酸碱度是影响土壤肥力的一个重要因素,它是土壤在长期发育过程中形成的。桑树生长与土壤酸碱度有密切关系,在不同的酸碱度条件下,桑叶的产量与质量,甚至桑叶养蚕的效果与制种质量常有不同,然而这方面过去积累的资料较少。我们对全省桑园土壤的酸碱度作了一些调查,1973年春并分析了全省30多个蚕种场的代表性土样,在此基础上进行整理,希望能掌握基本情况,并找出一些酸碱度变化的规律及其与桑树生长的关系,俾可作为桑园管理上的参考。土壤的酸碱度只是影响桑树生长的一个
Soil pH is an important factor affecting soil fertility, which is formed during long-term soil development. Mulberry tree growth and soil pH are closely related to different pH conditions, mulberry leaf yield and quality, and even the effect of mulberry sericulture and quality of seed production are often different, but in this area less accumulated in the past. We conducted some surveys on the pH of the mulberry fields in the province. In the spring of 1973, we analyzed the representative soil samples of more than 30 silkworm farms in the province and sorted out on the basis of this, hoping to grasp the basic situation and identify some The change of pH and its relationship with the growth of mulberry tree, serve as a reference for mulberry management. Soil pH is only one of the impact of mulberry growth
