1988和1989年我们在巴音郭楞州沙依东园艺场进行了库尔勒香梨喷施增产菌试验。供试的增产菌为北京农业大学植病生物防治研究室、南京生物农药厂联合生产,供试梨树为10年生库尔勒香梨,栽植株行距为4×6m,已进入盛果初期,树势中庸,管理较精细。增产菌喷施浓度设1 400,2 800和4 200ppm三个处理,每种浓度处理5株树,整株喷施,每次每株用菌液2L,年喷3次,连喷两年,1988年分别于4月18日(香梨初花期)、5月12日和6月8日喷施;1989年分别于4月9日(香梨初花期)、5月12日和6月14日喷施,与此同时选同园同龄同管理条件的5株香梨树喷清水做为对照。对处理树及对照,每株选部位、长势等相近的1—2个大枝,每年在第一次喷施前调查花芽量,5月下旬调查座果率,采收前(9月上旬)调查产 In 1988 and 1989, we conducted a Korla fragrant pear spraying increasing yield test in the Shayidong horticultural field in Bayinguoduou. The tested bacteria for the production of Beijing Agricultural University Plant Disease Prevention and Control Research Institute, Nanjing biological pesticide plant joint production for the test pear 10-year-old Korla fragrant pear planting spacing of 4 × 6m, has entered the early fruit Sheng, Moderate, more sophisticated management. The concentration of spawning bacteria was set at 1 400, 2 800 and 4 200 ppm respectively. Five trees were treated at each concentration. The whole plant was sprayed with 2L of bacteria solution per plant for 3 times per year. Even spraying for two years, 1988, respectively, April 18 (fragrant pear flowering), May 12 and June 8 spraying; 1989, respectively, on April 9 (pear early flowering), May 12 and June 14 Spraying on the same day, at the same time choose the same garden with the same management conditions of 5 pear spray water as a control. On the treatment of trees and control, each selected parts of the growing, similar to the 1-2 large branches, annual flower buds before the first survey, the late May survey fruit rate, before harvest (early September) survey Production
