草菇VP_(53)菌株,是采用原生质体诱变育种而成,是一个抗逆性强、产量高、质量好的优良菌株,在四川已进行了两年多的示范推广,取得了较好的效果。现将其特征特性及露地高产栽培技术介绍如下: (一)形态特征 草菇VP_(53)菌株的子实体菌雷白色至浅灰色,椭圆形,个体大(大小为5.5～8.0×2.5～3.5cm),单粒重15～30g,最大可达100g以上,单生或丛生,不易开伞。 (二)生长环境条件 ①温度:菌丝生长温度20～40℃,在15℃和45℃时生长停止,最适生长温度35℃左右。出菇温度20～35℃,最适25～30℃,在18℃以上菌蕾也不易死亡,是一个较耐低温的菌株。②酸碱度与光照:菌丝生长的pH值为4～11,最适6～7,在6～11之间菌丝长势差异不明显,日生长速度仅相差3～
Straw mushroom VP_ (53) strains, is a protoplast mutation breeding, is a strong resistance, high yield, good quality strains, in Sichuan has been carried out more than two years of demonstration and promotion, and achieved good Effect. Now its characteristics and open field cultivation techniques are described below: (A) morphological characteristics of fruiting bodies of mushroom VP_ (53) strains of fruiting bodies Lei white to light gray, oval, large individual (size of 5.5 ~ 8.0 × 2.5 ~ 3.5 cm), single grain weight 15 ~ 30g, up to 100g above, solitary or clustered, not easy to open the umbrella. (B) the growth of environmental conditions ① temperature: mycelial growth temperature 20 ~ 40 ℃, at 15 ℃ and 45 ℃ growth stopped, the optimum growth temperature of about 35 ℃. Fruiting temperature 20 ~ 35 ℃, the optimum 25 ~ 30 ℃, bacteria leaching is not easy to die above 18 ℃, is a more resistant to low temperature strains. ② PH value and light: the pH value of mycelial growth is 4 ~ 11, the optimum 6 ~ 7, between 6 to 11 mycelial growth difference is not obvious, the daily growth rate only difference of 3 ~
