The influence of biological fertilizer on crop growth research

摘要

Liao Star 20 as test materials, using three different concentrations of photosynthetic bacterial manure (respectively diluted 500 times, 400 times, 400 times) into the same amount of solution in the 500 ml beaker, the results were compared with equalparts water. After training in jointing stage of plant height, root length. After growth to the appropriate degree of indoor KaoZhong, measuring plant fresh weight and dry weight per plant. The results show that the different concentration of photosynthetic bacterial manure can obviously increase the rice growth conditions, the effect of diluted 400 times, 500 times to optimal; Photosynthetic bacterial manure can increase after jointing stage and leaf chlorophyll content, increase the photosynthetic rate, thus improve the biological yield, spraying 500 times, 400 times, 300 times the photosynthetic bacterial manure, respectively, compared with weight by 29%, 39.9%, 13.6%.
