从1972年开始,我们在蘑菇制种方面进行了多种配方试验,初步确认粪粒菌种比较理想。经龙山、文昌、阆中、巴中等地较大面积试验,普遍反映效果良好。1982年,元坝、三川、五龙66万平方尺栽培面积均采用了粪粒菌种,经济效益显著提高。制种盈利是发酵粪草料菌种的4倍(见表),栽培单位可降低成本21％,减少用工67％,提高产量10～20％,每千平方尺的蘑菇可增收100～200元。菇农称它是“量足质优、费省效宏”的好菌种。现将具体方法简述如下。
Since 1972, we conducted a variety of formula tests in the mushroom seed production, preliminary confirmed fecal species is ideal. The Longshan, Wenchang, Langzhong, Pakistan and other large area test, generally reflect the good results. In 1982, Yuanba, Sanchuan, Wulong 660,000 square feet of cultivated area are used in the fecal species, the economic benefits improved significantly. Seed production profit is 4 times that of fermentation dung material (see table). Cultivation units can reduce the cost by 21%, reduce the labor cost by 67% and increase the output by 10 ~ 20%. The mushrooms per 1000 square feet can increase 100 ~ 200yuan. Agro-agricultural called it “a good amount of quality, cost-effective macro” good species. Specific methods are outlined below.
