我县有大面积死黄泥土,土质粘重,酸性反应,养分不足,水源缺乏,作物生长不良,单产很低。这要影响我县农业生产发展的重要因素。为了培肥这类土壤,81年我们开始在大平进行土壤培肥试验,面积28~(?)5亩,82年又扩大到42亩,经过近两年的改土培肥,产量产值成倍增长,取得显著效果。现总结如下: 一、培肥措施根据该地土壤粘、酸、瘦等特性,我们采
My county has a large area of dead yellow soil, soil sticky, acidic reaction, lack of nutrients, lack of water, poor crop growth, yield is very low. This will affect the development of agricultural production in our county an important factor. In order to cultivate such soil, we started soil fertility test in Daping in 1981 with an area of 28mu ~ (5 mu) and an expansion of 42 mu in 1982. After nearly two years of soil improvement and fertilization, the output value of production has doubled Growth, achieved remarkable results. Are summarized as follows: First, fertilizer measures According to the soil sticky, sour, lean and other characteristics, we adopt
