对水稻秸秆品质进行遗传改良 ,选育出稻谷产量与推广品种相当、稻草品质优异的谷秆两用稻品种2 0 1。15N示踪表明 ,2 0 1能够把15N尿素有效地转化为稻草蛋白 (稻草15N回收率比CK高 10 4 .3% ) ;该稻草蛋白能有效地转化为菇体蛋白 (菇体15N回收率比CK高 2 1.7% )。 2 0 1优质稻草栽培草生食用菌 ,可提高菇产量和粗蛋白含量 :每公顷土地生产的 75 0 0kg稻草可增草菇 797.2kg、菇蛋白 6 7.9kg ;或增姬松茸6 75 .0kg、菇蛋白 80 .0kg。该优质稻草粉可替代等量麦麸栽培木生食用菌 (菇产量和粗蛋白含量与麦麸组没有显著性差异 )。栽培毛木耳、黑木耳、真姬菇、香菇、猴头菇时 ,稻草粉可替代占培养料总量 2 0 %的麦麸 ,栽培茶薪菇和金针菇时分别为 8%和 7.5 %。
Genetic improvement of rice straw quality, breeding of rice yield and promotion of similar varieties, excellent quality rice straw rice varieties 2 0 1.15N tracing showed that 2 0 1 15N urea can be effectively converted into straw protein (The recovery rate of straw 15N was 104.3% higher than that of CK). The rice straw protein could be effectively transformed into mushroom body protein (the recovery rate of 15N in mushroom body was 21.7% higher than that of CK). 2 0 1 High-quality straw cultivation of agaricus edible mushrooms can increase the mushroom yield and crude protein content: per hectare of land produced 75 0 0kg straw mushrooms can increase 797.2kg, mushroom protein 6 7.9kg; or Agaricus blazei 6 75 .0kg, Mushroom protein 80 .0kg. This high-quality rice straw can replace the equivalent amount of wheat bran cultivated edible fungi (mushroom yield and crude protein content and wheat bran group no significant difference). Rice straw fungus, black fungus, true hyssop, mushrooms, Hericium, rice straw powder can replace the total amount of 20% of the cultivation of wheat bran, cultivated tea mushrooms and mushrooms were 8% and 7.5%.
