花生接种根瘤菌是一项简便易行、经济实惠的增产措施,在亩产150公斤左右的生产水平下,一般能净增荚果15～20公斤,增产10％左右。70年代,徐州地区曾推广应用4～5万亩,起了一定的增产作用。随着生产条件的不断改善与土壤肥力的不断提高,花生产量成倍增长,继续使用花生根瘤菌是否仍然有效?为此,我们在高肥水平下,对几种不同根瘤菌剂的增产效果进行了试验。 材料与方法 1.试验菌剂:97-1,江苏徐州地区淮阴农科所生产;C_1、C_4,广东省农科院经作所生产;均为琼脂瓶装菌剂。 Peanut inoculation rhizobia is a simple, affordable stimulation of production measures in the production of about 150 kg per mu level, the general net pod 15 to 20 kg, an increase of about 10%. 70 years, Xuzhou area has been the promotion of 4 to 5 acres, played a certain role in increasing production. With the continuous improvement of production conditions and continuous improvement of soil fertility, peanut production doubled, the continued use of peanut rhizobia is still valid? To this end, we at high levels of fertilizer on the production of several different Rhizobium agents effect The test. Materials and methods 1. Test bacterial agents: 97-1, produced by Huaiyin Agricultural Science Institute, Xuzhou, Jiangsu Province; C_1, C_4, produced by Guangdong Provincial Academy of Agricultural Sciences; all were agar-containing bactericide.
