在食用菌生产中,常因培养料失水太多、太快而影响菌种质量和栽培物料的单位面积产量。我们生产了一种食用菌保水剂,它能使基质中的水分长期保存,从而达到食用菌在营养生长和生理生长期对水分的生理需求。现将应用结果简报如下: 一、保水剂的生产 (一)保水剂配方(份量比)丙烯酸70,马铃薯淀粉10,丙烯酸钠30。 (二)生产方法 将丙烯酸和丙烯酸钠在SCH螺带式混合机中混合均匀,加入水浴反应锅中与马铃薯淀粉水浴反应25分钟,然后再喷雾干燥即得保水剂聚合物粉剂,分装成500g塑料袋的小包装,即为商品食用菌保水剂。
In the production of edible mushrooms, often due to too much water loss of culture medium, too fast and affect the quality of species and cultivation of materials per unit area yield. We produce a water-retaining agent for edible fungi, which preserves the moisture in the matrix for a long period of time to achieve the physiological requirements for water for edible fungi during vegetative and physiological growth. Application results will now be presented as follows: First, the production of water retaining agent (A) water retaining agent formula (parts ratio) of acrylic acid 70, potato starch 10, sodium acrylate 30. (B) production methods Acrylic acid and sodium acrylate in the SC ribbon mixer mixed, added to the water bath reaction pot with potato starch water bath for 25 minutes, then spray drying to obtain water-retaining polymer powder, divided into 500g Small bags of plastic bags, that is, commercial water preservatives.
