摘要
1997～1998年对温室甜瓜施用CO_2的研究结果表明,在砂壤质土壤上,温室甜瓜施用CO_2后主茎增粗,抗病力增强,促进生长,成熟提早 2～4 d,甜度提高2.3度。产量增加25％～77.8％。
A study on muskmelon given CO2 in greenhouse had been carried out in Langfang from 1997 to 1998. The results showed that the main stem turns thicker and the power of disease-resis-tance turned stronger when muskmelon plants grown in the sandy soils in greenhouse were given CO2. It can promote growth of plants and make mature earlier 2-4 days than the normal. The sweet degree was improved 2.3?yield was increased 25-77.8% .
