我省夏播绿肥柽麻经多年试种、示范,目前已推广近6万亩,予计在今后将有更大发展。 1977年和1978年,我们在临猗等县柽麻现蕾期挖根调查,每百株统计结果是:结瘤植株占40.8-78.3％;每株主根有效根瘤为0.11-0.49个、白色无效根瘤0.17-0.66个,侧根上有效根瘤0.34-1.6个,白色无效根瘤1.17-2.39个。百株主根根瘤鲜重为0.41-2.2克,侧根为1.79-4.86克。这一低水平的结瘤状况说明:在我省种植柽麻的土壤中,缺少适宜宿主侵染力强、固氮力
Summer sowing of green manure in our province after years of trial planting, demonstration, has now promoted nearly 6 million mu, is expected to have greater development in the future. In 1977 and 1978, we surveyed Lin’an county budding period budding, the statistical results per hundred: nodulation plants accounted for 40.8-78.3%; effective root nodules per plant root 0.11-0.49 white invalid 0.17-0.66 nodules, 0.34-1.6 effective root nodules on the lateral root, and 1.17-2.39 white nodules. One hundred root nodules fresh weight 0.41-2.2 grams, lateral root 1.79-4.86 grams. This low level of nodulation shows that: in the province planted sow linen soil, the lack of suitable host infectivity, nitrogen fixation
