不同秸秆发酵菌曲催化剂对日光温室生菜生长效果的研究

秸秆发酵菌曲催化剂是添加在秸秆发酵菌中的一种触媒,是实现秸秆快速腐熟的重要材料。选择尿素、羊粪、牛粪3种秸秆发酵菌曲催化剂,对各自不同施用量的效果进行对比试验,研究不同催化剂对山西省晋中盆地日光温室生菜的生长情况、品质、矿质元素和叶绿素值的影响。结果表明:3种催化剂均可以对生菜的生长情况、品质、矿质元素含量和叶绿素值产生不同程度的影响,其中羊粪效果最佳,牛粪次之,尿素效果第三。在各种处理中,羊粪的最佳施用量为400 kg/hm2,牛粪的最佳施用量为400 kg/hm2,尿素的最佳施用量为360kg/hm2。

Study on Effects of Different Catalysts of Fermentative Production From Cronstalks on Lettuce Growth in Sunlight Greenhouse

The catalyst of fermentative production from cornstalks is an important catalyst which is added to microbial fermentation agent for acceleration decomposition of cornstalk.Three tested catalysts like as carbemide,sheep manure and cattle manure were chosed in this experiment.The effects of different catalysts on the growth,quality,mineral element and spad value of lettuce in sunlight greenhouse were studied based on three catalysts contrast test.The results showed that the three tested catalysts all had different degrees on the growth,quality,mineral element and spad value of lettuce,the best was sheep manure,cattle manure took the second place,and carbamide was the third.The best application rates of sheep manure and cattle manure were both 400 kg/hm2,360kg/hm2 was the best application rates of carbamide.
