摘要： 在连作棉田上进行春小麦复播绿肥（草木樨、油菜、油葵、大豆）试验，研究各种绿肥生物量，养分含量及其绿肥翻压后对棉田土壤有机质，速效养分的影响。研究结果表明：四种绿肥中草木樨的生物量最高；四种绿肥翻压后对土壤有机质和速效养分含量均有一定的影响，其中草木樨、大豆翻压后土壤有机质分别提高了8.58%，1.01%；四种绿肥翻压后土壤速效氮提高了0.30%-5.96%，除大豆外，其它三个处理的土壤速效钾含量平均是对照的1.08倍；研究发现油菜、油葵的富钾作用较为突出。四个处理中春小麦复播草木樨是相对较好的一组轮作作物。

Abstract: Experiment about spring wheat and green manure(Melilotus suaveolens,Rape,Oil sun flowers,soybean)on the continous cropping cotton fields, study their biomass ,plant nutrient content and the effect of green manure application on soil nutrients in cotton fields.The results showed that: biomass in the Melilotus suaveolens is the highest in four green manure; after pressed four green manure in the Green the cotton fields, soil organic matter,nutrients are available certain influence; after Melilotus suaveolens and soybean pressed in the soil,organic matter increased by 8.58% and 1.01%;four green manure pressed in the soil available nitrogen increased by0.30%-5.96%,except soybean, the soil available potassium of the other three dealt is 1.08 times that of the control; the role of rich potassium in Rape and Oil sun flowers are even more significant .This experiment researched spring wheat mutiple Melilotus suaveolens is a relatively good crop rotation.
