光合细菌对水稻生育、产量及效益影响的研究

Studies on Effect of Photosynthetic Bacteria on Growth, Yield and Benefit of Rice

利用光合细菌延农光配1号,对水稻叶龄、株高、分蘖数、出穗期及产量进行了研究。结果表明,不同处理对水稻叶龄及有效分蘖数无明显差异,但对水稻株高和出穗期有差异,说明延农光配1号具有促进生长、早熟的作用。产量和经济效益分析表明,未腐熟的猪粪40 m3/hm2和光合细菌100 L/hm2,产量极显著高于对照,其经济效益高出对照8 381元/hm2。

The effect of application of photosynthetic bacteria of ＇ Yannongguangpei No. 1 ＇ to leaf age, plant height, numbers of plants, panicle stage and yield of was studied. The results indicated that there was no significant difference in leaf age and effective plant numbers among different disposal, whereas there were differences in plant height and panicle stage. This indicated that ＇Yannongguangpei No.l＇ could promote rice growth and made them ripen earlier. Yield of Treatments of 40 m^3/hm^2 pig feces and 100 L/hm^2 photosynthetic bacteria to subsoil was extremely higher than the control. The economic benefit increased 8381 yuan/hm^2 compared with the control.
