Field management method for melon facility long-season cultivation

Disclosed is a field management method for melon facility long-season cultivation. The method comprises the steps that dual-root-cut-grafting floating seedling growing is adopted; dual-vine pruning is carried out, and a robust secondary vine is selected to firstly bear one melon; after a first batch of melons expands, the other vine is made to bear one melon, old vines bearing melons are pruned off after the first batch of melons is mature and harvested, compound fertilizer and water are applied once to promote unfixed vines of plant roots to sprout and grow, one robust unfixed vine is selected and kept, foliage dressing is carried out, and vigorous growth of new vines is promoted; after a second batch of melons expands, the reserved new vines bear one melon, old vines bearing melons are pruned off after the second batch of melons is mature and harvested, compound fertilizer and water are applied once to promote the unfixed vines of the plant roots to regenerate, one robust unfixed vine is selected and kept as a melon bearing vine of the next batch of melons, and foliage dressing is carried out to promote vigorous growth of the next batch of melon bearing vines; the steps are operated repeatedly, and total at least five batches of melons are produced and harvested. According to the method, multiple melons can be harvested through one plant, and the aims of reducing cultivation links, being high in yield and efficient and achieving long-season cultivation can be achieved.
