提高哈密瓜品质是一个很重要的问题,1979年我们在鄯善红旗公社进行试验,喷施低分子量腐植酸能使哈密瓜含糖量增加0.9%以上(绝对值),座果率增加10%,1982—1984年我们以哈密瓜作为主要对象,研究了腐植酸对哈密瓜品质的影响,现将三年试验结果综合总结于下:一、通过试验表明:高分子量腐植酸 Improving the quality of cantaloupe is a very important issue. In 1979, we experimented in Shanshan Hongqi Commune. The spraying of low molecular weight humic acid increased the sugar content of cantaloupe by more than 0.9% (absolute value) and the fruit set rate increased by 10%. In 1982, - In 1984, we used cantaloupe as the main object to study the effect of humic acid on the quality of cantaloupe. Now the three-year test results are summarized in the following: First, the experiment shows that the high molecular weight humic acid
