今年我区从省农科院土肥所引进新型生物肥料——菜豆根瘤菌,井在全区1,000亩菜豆地上设点进行了生育期和产量的调查测定。据于洪乡、杨士乡、造化乡等试验点所测结果,表明施用根瘤菌肥可使菜豆根瘤数和产量明显增加。于洪乡张玉兴在20平方米小区面积上,设两次重复和对照试验,生育期中进行两次根瘤数及植株干鲜重调查,结果根瘤数比对照增多达极显著。5次采收累计产量,
This year, our region from the provincial Academy of Agricultural Sciences introduced a new type of biological fertilizer soil fertilizers - bean rhizobia, and 1,000 acres of beans in the region set up a point on the growth period and yield survey. According to Hongxiang, Yang Shih-hsiang, made of the test points such as the results of the test, indicating that the application of rhizobium fertilizer bean bean nodules and yield increased significantly. Yu Hongxiang Zhang Yuxing area of 20 square meters in the plot, set up two repeat and control trials, two nodules during the growing season and plant dry weight survey, the results nodules increased significantly more than the control. 5 times the cumulative harvest,
