用稻草栽培侧耳,一般要求选择收割时茎叶已充分黄熟的稻草做原料,才能获得较好的产量。但目前水稻产区,大多栽培早熟品种,且氮素化肥施用量较大,从而造成收割时稻草普遍呈青黄状。这类稻草由于植物细胞壁未完全木质化和纤维化,结构水含量高,用它栽培凤尾菇和某些抗逆性较差的平菇菌株,播种后菌丝往往很难正常增殖,稻草很快变黑腐败,造成大幅度减产,甚至绝收。针对这一新情况,笔者从选育抗逆性较强之品种入手,于1991年从广西生物
With ear cultivation of straw, the general requirements of harvesting stems and leaves have been fully cooked straw raw materials, in order to obtain better yields. At present, however, rice-producing areas mostly cultivate early-maturing varieties, and nitrogenous fertilizer is applied in a large amount, resulting in a general yellowish-yellow straw at the time of harvesting. Such straw because the plant cell wall is not completely lignified and fibrosis, the structure of high water content, use it to cultivate Pleurotus ostreatus and some less-resistant strains of Pleurotus ostreatus, seeding mycelium is often difficult to normal proliferation, straw is Quickly turn black and corrupt, resulting in a substantial cut, or even fail. In response to this new situation, the author start with breeding varieties with higher resistance, from Guangxi in 1991
