棉子壳栽培平菇,方法简单,产量高。但近年来平菇栽培面积迅速扩大,棉子壳供不应求,在非产棉区更为短缺。为了寻求当地新的栽培料,我们于1993年利用食品添加剂厂的下脚废料——甘草渣进行平菇栽培试验,取得了较理想的效果。现简报如下: 一、材料和方法 (一)选料和处理 选新鲜未霉变的甘草渣,分别进行制种和袋式栽培试验,并以棉子壳为对照。制种用料配方为:甘草渣78％,麸皮18％,白糖、石膏各1％,过磷酸钙2％,湿度调至用手握料指缝见水但不下滴,pH值自然。栽培用料配方为:甘草渣78％,玉米粉、麸皮各10％,石膏、过磷酸钙各1％,另加0.2％的尿素和0.4％的生石灰,湿度和pH值均与菌种料相同。制种用料装入瓶中,在1.3～1.5kg/cm~2压力下湿热灭菌1.5～2小时,栽培用料装袋(袋规格20×40cm)后在土蒸锅灭菌8小时。对照组除主材料用78％的棉子壳代替甘草渣外,辅料及处理方法均同上。
Moss shell cultivation mushrooms, the method is simple, high yield. However, mushroom cultivation area in recent years, the rapid expansion of cotton seedlings in short supply, a shortage of non-producing cotton more. In order to find a new local planting material, we used the waste additive of licorice residue in the food additive factory to carry out the mushroom cultivation experiment in 1993, and achieved satisfactory results. Now briefings are as follows: I. Materials and methods (a) selection and processing of fresh and unmotrope selected licorice residue, respectively, seed and bag cultivation experiments, and cotton as shell control. Seed production materials formula is: 78% licorice residue, bran 18%, 1% of white sugar, gypsum, superphosphate 2%, humidity adjusted to see the water with the hand holding material but not dripping, the pH value of natural. Cultivation materials recipe: licorice residue 78%, corn flour, bran 10%, gypsum, superphosphate 1%, plus 0.2% urea and 0.4% of the quicklime, humidity and pH are with the germ material the same. The materials for seed production are put into bottle and wet-heat-sterilized for 1.5 to 2 hours under the pressure of 1.3-1.5 kg / cm 2. The materials for cultivation are bagged (bag size: 20 × 40 cm) and sterilized in a soil steamer for 8 hours. In addition to the control group 78% of the main material instead of licorice residue cotton seed, excipients and treatment methods are the same.
