生物质改良剂对康平地区风沙土保水效果及作物生长发育的影响

研究生物质改良剂对康平风沙土保水效果以及作物生长发育的影响，探讨了生物质改良剂对作物产量提高的机制。研究结果表明：与传统种植处理相比，生物质改良剂能改善风沙土理化性质，显著提高土壤含水量；与有机肥处理相比，生物质改良剂不但能增加土壤含水量，而且能促进作物更好的生长发育。生育同期的玉米株高、叶面积、干物质累积量以及玉米最终产量都要好于传统种植处理和有机肥处理。

The Effect of Biomass Modifiers on Water Retention and Crop Growth in Sandificational area of Kangping

The paper analyzes the effect of biomass modifiers on water retention and crop growth in Sandifica-tional area,and explores the mechanism of biomass modifiers on crop yield increase.The results show that:compared with traditional planting treatment ,biomass modifier can improve physical and chemical properties of aeolian sandy,significantly improve the soil moisture;compared with organic fertilizer,biomass modifiers can not only increase soil moisture,but also promote plant growth and development,in the same period,plant height,leaf area,dry matter accumulation,corn yields are better than traditional planting processing and organ-ic fertilizer.
