小麦根际联合固氮菌肥是一种新型生物肥料,我站于1988年秋进行小区试验,1989年开始推广应用,1990年全乡应用面积已达1700多亩,占小麦面积的20％左右,增产幅度均在10％左右。为了进一步探索小麦根际联合固氮菌肥的应用效果和最佳用量,1990年继续开展了这方面的研究。 材料与方法 试验地为粘土,肥力中等,播前用绿麦隆化除。 供试品种:扬麦5号,10月25日耕翻撒播,每亩用种量10千克。 试验设计:设5个处理,分为亩施菌肥250克、500克、750克、1000克,以不施菌肥作对照,采用大区比较,随机排列,不设重复,每处理1亩。
Wheat rhizosphere nitrogen fixation bacteria and fertilizer is a new type of biological fertilizer, I stood in the autumn of 1988 to test plots, began to promote the application in 1989, the township in 1990 the area has reached 1700 mu, accounting for about 20% of the wheat area, yield The magnitude is about 10%. In order to further explore the application of rhizosphere nitrogen fixation in wheat rhizosphere and the best dosage, in 1990 continue to carry out this research. Materials and methods The test for the clay, medium fertility, before sowing with chlorotoluron. Test varieties: Yang Mai No. 5, October 25 tilling overcast broadcast, with 10 kg per acre species. Experimental design: Set 5 treatments, divided into 250 grams of Mushi fertilizer, 500 grams, 750 grams, 1000 grams, with no fertilizer as a control, the use of large areas, random arrangement, without duplication, each processing 1 acre .
