【摘要】：通过开展砂质中低产田土壤质地改良小区试验,研究了从黄河河道抽取黄河泥沙改良砂质土壤质地的效果,从而分析得出使用黄河泥沙的数量和提高小麦产量之间相关关系,通过在砂土中掺加高黏黄河泥沙试验,对比研究了土壤质地和含水率的变化情况。结果表明,砂质土壤中掺加高黏黄河泥沙,改变了土壤质地结构,提高土壤保墒能力,增强持水性。同时在土壤质地改良的基础上测试了掺加高黏黄河泥沙不同比例对小麦产量变化的影响,掺量少的试验小区小麦产量未见明显提升,掺量大的试验小区小麦产量显著提升,可以达到未改良土地小麦产量的2倍以上。
[Abstract]:In this paper, the effect of improving sandy soil texture by extracting Yellow River sediment from the Yellow River was studied through the soil texture improvement plot experiment in sandy medium and low yield field, and the correlation between using the Yellow River sediment quantity and increasing wheat yield was analyzed. The changes of soil texture and moisture content in sandy soil were studied by adding high viscosity yellow river sediment into sandy soil. The results showed that adding high viscosity yellow river sediment to sandy soil changed soil texture and improved soil moisture conservation ability. At the same time, on the basis of soil texture improvement, the effect of different proportion of high viscosity Yellow River sediment on wheat yield was tested. The yield of wheat in the experimental plot with large amount of adulteration was significantly increased, which could be more than 2 times of the yield of wheat in unimproved land.
