柽麻是一种较耐旱、耐瘠、速生的夏播短期绿肥。近年在所内和省内各地试验示范中可以明显的看出,不同肥力的土壤对柽麻肥效影响很大,特别是对土壤磷素养分反应很敏感,可说是决定柽麻压青增产显著与否的关键因素之一。为了探讨不同肥力土壤和施肥因素与柽麻肥效的关系,充分发挥压青后当年的肥效,摸索适当的施肥措施,我们于1975～76年进行了试验。一、试验处理: 采用盆栽方法进行,土壤分缺磷和较不缺磷两种,缺磷土壤取自附近生产队,较不缺磷土壤取自省农科院试验农场。经分析,两种土壤养分含量参看表1。
Ma flax is a more drought-tolerant, barren, fast-growing summer sowing short-term green manure. In recent years in the province and throughout the pilot demonstration can be clearly seen that different fertility of the soil on the effect of hemp great effects, especially for soil phosphorus nutrient sensitivity is very sensitive, it can be said that the decision to press the green flaxseed significantly increased yield and No one of the key factors. In order to explore the relationship between different soil fertility factors and the fertilizer efficiency, give full play to the fertilizer efficiency in the current year and explore the appropriate fertilization measures, we carried out the experiment in 1975-76. First, the experimental treatment: potted method, the soil points less phosphorus and less phosphorus deficiency, phosphorus-depleted soil from the nearby production team, less phosphorus-free soil from the Provincial Academy of Agricultural Experimental Farm. After analysis, two kinds of soil nutrient content see Table 1.
