摘要
为探讨农牧结合种植方式进行了5年的玉米草木樨2∶1间作试验。结果表明,玉米间作草木樨可改善玉米群体透光水平;增加饲用蛋白质产量75%;而且对土壤供肥状况和后作也有良好的影响,在作物生育期间玉米和草木樨无明显争水争肥现象;包括草木樨所占面积,间作玉米仍可获得相当于清种93.6%的籽粒产量。
The experiment of the intercrop of corn of 2 rows and sweet clover of 1 rows was carried out during last five years, for getting a new way combining the crop production and livestock. The results showed that the sunlight inside the canopy of the corn in the intercrop was improved and the output of feed protein from the intercrop was increased at 75%. In addition, intercrop made a good effect on the soil fertlity and after crops. The grain yield of the corn in intercrop was 93.6% of the corn monoculture although the corn in the intercrop only grew on the 2/3 land area of the monoculture.
