A field management method for long-season cultivation of melon facilities

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of melon cultivation, and in particular relates to a field management method for long-season cultivation of melon facilities. Background technique [0002] Melon is an important economic crop. The economic benefit of its cultivation is good, especially the economic benefit of protected cultivation is very considerable. In many areas, melon cultivation has become an important way to increase farmers' economic income. my country is a big producer and consumer of melons, with an annual sown area of ​​590,000 hectares and a total output of 14.62 million tons, accounting for 46% and 53% of the world's sown area and total output, respectively. Therefore, my country's melon production occupies an important position in the world (Bie Zhilong. my country's watermelon and melon grafting seedling industry development status and countermeasures. China Melon, 2011,24(2):68-71). As an important high-efficiency economic c...

Problems solved by technology

Thick-skinned muskmelon has been successfully cultivated in greenhouses and other facilities in the rainy and humid middle and lower reaches of the Yangtze River and other southern regions, and has produced good economic benefits. High cost, always unable to form large-scale production

Wei Wuqing and others discussed the long-season cultivation mode and supporting technology of thick-skinned melon (Wei Wuqing, Yan Yanhua. Long-season cultivation mode and supporting technology of thick-skinned melon. Shanghai Vegetables, 2012, (6): 63-64). The contribution is that 1 crop of melons under protected cultivation can harvest 2 batches of muskmelons, and a total of 4 batches of muskmelons can be harvested through each facility cultivation of 1 crop of muskmelons in spring and autumn, thereby achieving the purpose of long-season cultivation and annual balanced supply of melons; its disadvantages The reason is that this long-season cultivation mode is not a real long-season cultivation, because only two batches of melons can be harvested per crop of melons, and one crop of melons needs to be cultivated in spring and autumn to achieve the purpose of long-season cultivation and supply. To cultivate one crop of melons, the processes of soil preparation, sowing, seedling raising, and planting must be repeated, which is labor-intensive, labor-intensive, and time-consuming, and it is difficult to cultivate large areas.

Long-season cultivation techniques of muskmelons such as Wang Yuhong (Wang Yuhong et al. Long-season cultivation techniques of muskmelons in greenhouses. Ningbo Agricultural Science, 2009, (4): 28-30), its contribution is that after harvesting 2 batches of muskmelons in the early-maturing cultivation of muskmelons in greenhouses, Cut off the old vines that have produced fruits, and then prune the branches to keep the fruit after the new vines are released. One crop of melons can be harvested continuously for 3 to 4 batches of melons, which can be said to be long-season cultivation in the true sense; Seasonal cultivation technology actually belongs to the general regenerative cultivation technology. Since the old vines are cut off directly after the melon is harvested, the growth balance between the above-ground part and the underground part of the plant is suddenly destroyed, which accelerates the aging of the melon root system, and its growth and absorption capacity decline, leading to slow germination of latent adventitious buds at the base of the melon plants, weak growth of pumped adventitious vines, and some individual aging plants even died early, unable to sprout adventitious vines and appeared short of shoots, so the yield of regenerated melons was higher than that of the first two batches The yield of melons is much lower, and the quality is also poor, and only 3 to 4 harvests of one species have been realized, so the actual promotion and application value is not great

A method for planting thick-skinned melons with multiple harvests in one batch (application number 201410699575.7, application publication number CN 104350936A). Compound fertilizers are applied 12 to 18 days before the first batch of melons are harvested to promote the germination of new side vines at the roots, and cut them when harvesting. Cutting the fruiting vines and retaining a strong vine at the root for the next fruiting can partially overcome the above-mentioned defects of the regenerative cultivation technology. At least 3 batches of melons can be harvested by cultivating one crop of melons. The consumption is large, and the conventional fertilizer and water management technology is used. The melon plants and roots are easy to age, and the growth potential of the new lateral vines is poor, and the aging is fast, so the yield and quality of the next few batches of melons are low.
