1980年,北京农业大学植病生防研究室和山东省农科院植保所以及山东植检站共同设计,在山东泰安、莱芜、诸城等九个县(市)布点,进行综合防治试验,以贯彻农业措施为主,结合增施益菌,以达到防病增产目的。试验分为常肥区,即生产上亩产五、六百斤产量的施肥水平,每亩施土杂肥1万斤,氮肥18斤(硫铵折纯氮),磷肥10斤(磷酸钙折五氧化二磷)。高肥区,即生产上八、九百斤产量施肥水平,每亩施土杂肥1万斤,氮肥24斤,磷肥12—15斤。试验中施用的益菌,系从
In 1980, the plant disease prevention and control research center of Beijing Agricultural University and the Plant Protection Institute of Shandong Academy of Agricultural Sciences and the Shandong Plant Inspection Station were jointly designed to carry out integrated control trials in nine counties (cities) such as Tai’an, Laiwu and Zhucheng in Shandong Implementation of agricultural measures, combined with the benefits of bacteria, in order to achieve the purpose of disease prevention and increase production. The experiment is divided into the common fertilizer area, that is, the fertilization level of 500 to 600 kg of output per mu in production, 1 kg of soil mixed fertilizer per mu, 18 kg of nitrogen fertilizer (pure nitrogen of ammonium sulfate), 10 kg of phosphate fertilizer Phosphorus pentoxide). High-fat area, that is, the production of eight, nine kilograms of yield fertilization level, Shi Mushi fertilizer per acre 1 kg, 24 kg of nitrogen, phosphate fertilizer 12-15 kg. Used in the test of bacteria, from
