小土黄泥是红黄壤中的一种低产土壤类型,全省有427万亩,其中盆西平原成片分布于西河以西的10多个县即有192万亩。这些地区人平耕地较多,粮、油商品率高,改良和利用好小土黄泥,对加速本区粮油基地建设,促进农业现代化有重要意义。我们自1976年在夹江县土门公社建立基点以来,采取定位研究与面上调查,试验、示范和推广相结合的方法,取得了初步研究结果,现简报于下。
Small soil yellow mud is red and yellow soil in a low-yielding soil types, the province has 427 acres, of which the western plain of the plain is distributed in more than 10 counties west of the Xihe have 192 million mu. In these areas, there are more people who planted more land, and the rate of grain and oil products is high, and the improvement and utilization of small clay are of great significance to speeding up the construction of grain and oil bases and promoting agricultural modernization in this region. Since we established the base point in Tumen commune of Jiajiang County in 1976, we have taken the method of combining the research on location with on-the-spot investigation, experiment, demonstration and promotion. We have obtained preliminary research results and are briefed below.
