我国黄淮海平原地区,土壤肥力水平一般都不高,而且有旱涝盐碱的危害,对农业生产带来不少的影响。翻压绿肥和施用厩肥是改良土壤瘠薄和抑制盐碱为害的重要农业生物措施之一,在这一方面,我国许多农业科学工作者做了不少工作。但从土壤复合体性质的变化来阐明有机肥料改良土壤的作用是较少的。为此,我们在河南省封丘县应举公社西大村大队进行田间试验。对连续翻压绿肥和施用厩肥的增产作用和对上壤复合体特性的影响进行研究,探索有机肥料改良土壤的机制。
China Huang-Huai-Hai Plain, soil fertility levels are generally not high, but also the hazards of droughts and salina, agricultural production has brought a lot of impact. Turns green manure and the application of manure is one of the important agricultural biological measures to improve soil infertility and salinity-alkali damage. In this aspect, many agricultural scientists in our country have done a lot of work. However, the change of the nature of the soil complex to clarify the role of organic fertilizers to improve the soil is less. For this reason, we conducted a field trial in Fengqiu County, Henan Province, where the brigade of Xidadu commune commune should be held. The effects of continuous green manure and manure application on the yield increase and the characteristics of the soil complex were studied to explore the mechanism of organic fertilizers to improve the soil.
