摘要
温棚室内ＣＯ２不足是影响温棚蔬菜生产的重要因素之一。温棚人工增施ＣＯ２的方法很多，但都有一定的局限性。作者根据现在温棚室的实际情况研制出了一种新型高效的ＣＯ２发生剂——固体气肥发生剂，对比试验表明，该发生剂能使蔬菜增产２５％以上，投入产出比在１∶６以上，并且具有无污染无公害的特点。
The shortage of CO 2 is one of the important factors affecting vegetables production in the greenhouse or shed.There are many methods of artificial adding CO 2 into the greenhouse or shed,but there are a lot of defects.On the basic of the actual situation of the greenhiuse or shed,a new type of chemical preparation of the high efficient solid gas fertilizer has been manufactured.The experimental results show that solid gas fertilizer enables vegerables to increase production by 25%,input/output value ratio is about 1∶6,it has peculiarity of social benefits of non pollution,and it had a favourable reception of peasants.
