风砂土是黑龙江省西部半干旱地区的主要耕地土壤之一,面积达500万亩左右。分布在松嫩平原的河漫滩和一级阶地区。当地热量充足,雨热同季,产量潜力很大。但由于此类土壤跑风、漏水、漏肥,抗旱力差,所以产量很低。为发挥风砂土的增产潜力,提高单产,我们利用泡底黑土进行了改良风砂土的试验,结果表明改土效果好,增产显著。
Windy sand is one of the major arable soils in the semi-arid areas of western Heilongjiang Province, with an area of about 5 million mu. Distribution in the Songnen Plain floodplains and a first-order area. Local sufficient heat, heat and rainy season, great potential for yield. However, due to run-off of such soil, leakage, leakage of fertilizer, poor drought resistance, so the yield is very low. In order to give play to the yield potential of aeolian sandy soil and increase yield, we conducted experiments on amelioration of aeolian sandy soil by using soaked black soil. The result shows that soil improvement is good and yield is significant.
