多年来,人们习惯用三层生料二层生产种散、条和点播法栽培竹荪,此法用料量大(每亩2000kg),菌种用量多(3～5kg/m~2三级种),播种时菌种破碎发菌慢(约30天左右);生料栽培杂菌多,营养分解慢,从播种到采完后潮荪需3年管理时间,管理费用大。笔者于1991年秋至1993年秋采用竹荪复壮种露地熟料栽培用料节省2/3(每亩仅利用林中落地废枝叶600kg),菌种成本低(5kg/m~2复壮种),播种时菌种不破碎,新菌丝生长快又壮,半个月就能长满新菌1cm,出荪齐、成品率高,产量由原来的42g/m~2提高到98g/m~2左右。出荪管理时间由原来的近3年缩短至9个月左右。现将该技术要点总结报道如下:
Over the years, people are accustomed to using three layers of raw materials to produce second-grade seed dispersions, strips and on-demand cultivation of Dictyophora, this method with large amount of material (2000kg per acre), the amount of bacteria more (3 ~ 5kg / (About 30 days); raw materials and more miscellaneous bacteria, slow decomposition of nutrients, from sowing to harvest after the tidal sun need 3 years of management time, management costs. In the fall of 1991 to autumn of 1993, the author used the Dictyophora multiflora open-cut clinker to save 2/3 materials (only 600 kg waste per mu of waste wood in the forest), low cost (5kg / m ~ 2 rejuvenation), sowing When the bacteria species is not broken, new hyphae grow fast and strong, half a month can overgrow new bacteria 1cm, Sun-homogeneous, high yield, yield from the original 42g / m ~ 2 to 98g / m ~ 2 or so . Sun-management time from the original nearly 3 years reduced to 9 months or so. The summary of the technical report is as follows:
