保水剂是中国农科院作物研究所研制,是一种高分子物质,应用于粮食作物的拌种上,在作物种子表面形成包被,并能储存一定量水分,从而可提高作物的抗逆性,增加粮食产量.我们在栽培姬菇的培养料中加入保水剂进行试验,由于增加了培养料的蓄水量,特别是当空气湿度偏低,培养料保湿困难时供给菌丝利用,从而可显著地提高姬菇产量. Water-retaining agent is developed by Institute of Crops, Chinese Academy of Agricultural Sciences, is a kind of macromolecule material, which is applied to the seed dressing of food crops and forms a coating on the surface of crop seeds and can store a certain amount of water so as to increase the resistance of crops Sexual, and increase food production.We cultivate Shimei culture material by adding water-retaining agent for the test, due to increase the water storage capacity of the material, especially when the air humidity is low, the supply of nutrients to mycelium difficult to moisturizing the material to Can significantly improve the Shimei yield.
