油菜是我县主要的夏收作物。1981年油菜播种面积7.54万亩,占夏收作物播种面积的63.89%,高峰和城关两区油菜播种面积占夏收作物面积的80%以上。油莱生产的发展,为水稻生产开辟了肥源,油菜秸秆、荚壳、油饼等还田,具有显著的增产作用,为了弄清油菜杆还田的增产效果,适宜的施用量和施用方法,我们进行油菜杆还田的水稻丰产栽培试验和不同秸秆用量比较试验。现将试验结果简要报告如下:
Rape is my main summer harvest crops. In 1981, the planting area of rapeseed was 75,400 mu, accounting for 63.89% of the sown area of summer harvest. The sown area of rape in peak and Chengguan area accounted for more than 80% of the area harvested in summer. Oil rapeseed production has opened up fertilizer sources for rice production, rape straw, pod shells, oil cakes and other fields, with a significant increase in production, in order to clarify the yield rape stems, the appropriate application rate and application methods, We carried out rape straw in paddy field high yield cultivation experiments and different amount of straw experiment. The test results are now briefly reported as follows:
