本文根据两个年度的播期与菌种正交试验结果,南京地区的最佳播期为A_1(9月下旬)和A_5(2月下旬),优良平菇菌种为B_1佛罗里达,B_2上海东平。播期和菌种组合A_1B_2、A_1B_1和A_(?)B_1具有明显优势,产量和生物效率均较高。在大田小棚人工管理条件下,适播的温度指标,秋季为棚内科中温度30℃,换算成大气温度为24—25℃,春季为料温6℃,即稳定上升到1℃的气温.分析南京33年的历史资料,各旬气温变化平稳,没有奇异特征。因此,选用优良平菇菌种,根据当时温度情况,适时播种是能获成功的. According to the results of sowing date and strain orthogonal test in two years, the best seeding date in Nanjing was A_1 (late September) and A_5 (late February), the best Pleurotus ostreatus was B_1 Florida, B_2 Shanghai Dongping . The sowing date and strain combinations A_1B_2, A_1B_1 and A_ (-) B_1 had obvious advantages and high yield and biological efficiency. In the field under the conditions of man-made shed management sowing temperature indicators, the autumn shed temperature of 30 ℃, converted to atmospheric temperature of 24-25 ℃, the spring temperature of 6 ℃, that is, stable rise to 1 ℃ temperature. Analysis of the historical data of 33 years in Nanjing, the temperature changes at each ten-day stable, no strange features. Therefore, the selection of good Pleurotus ostreatus, according to the prevailing temperature conditions, timely sowing can be successful.
