摘要：

将不同原料按一定配方混合配成育苗基质，采用穴盘育苗与盆栽试验，通过对‘早春红玉’西瓜穴盘育苗的幼苗素质和移栽后的生长状况的观测，探讨蚓粪基质在克服西瓜连作障碍方面的应用效果。结果表明，蚓粪复合基质处理的西瓜早期幼苗株高、茎粗、叶片数、单株干重、壮苗指数等指标均显著高于其他各处理。移栽后期，蚓粪复合基质育苗的植株在克服西瓜连作障碍方面表现明显，2种蚓粪复合基质育苗的植物死亡率仅为27.5%和22.5%，显著低于其他各处理。蚓粪复合基质育苗的植株主蔓长度最长，分别达162.1、171.8 cm，显著高于其他各处理。蚓粪基质育苗处理的西瓜中心糖度、边糖度均显著高于其他各处理，其中70%蚓粪基质、90%蚓粪基质处理的西瓜中心糖度分别为13.5%、12.9%，边糖度均为10.3%。

Abstract:

In this study, different substrates made of worm casts were used for both plug and pot cultivation of watermelon seedlings. The growth index of seedlings after transplanting were determined, in order to study the effects of worm cast substrates on relieving the growth obstacles caused by successive cropping of watermelon. The melon variety used was ‘Zao chun hong yu’. The results showed that the height and thickness of the seedlings, as well as the numbers of leaves and healthy of the melon seedling treated with complex worm cast substrate were higher than those of non-treated ones. In the later stage of transplanting, when cultivated in two types of worm cast substrates, the seedling had death rates of 27.5% and 22.5% respectively. The longest melon vines were 162.1 and 171.8 m, and the thicknesses of melon skin were 4.63 and 4.83 meters. Higher sugar content was detected for the melons. The sugar contents of the melons cultivated using 70% and 90% worm cast substrates were 13.5% and 12.9% respectively. The above index was significantly better than those cultivated in other substrates.
