A plant adjustment method for long-season cultivation of muskmelon

Abstract

The invention discloses a plant adjusting method for muskmelon long-season cultivation. The plant adjusting method for muskmelon long-season cultivation includes the steps that when a muskmelon vine grows to 30-50 cm long, pruning begins, and one main vine is retained; first, the main vine is made to bear a muskmelon, after the first batch of muskmelons expand, one more muskmelon is borne, and a strong randomly selected vine sprouting at the stem base of the plant is retained as a fruiting vine for the next batch of muskmelons; after the first batch of muskmelons are harvested, the fertilizer and water management is strengthened to promote the expansion of the second batch of muskmelons and the strong growth of the retained fruiting vine; one muskmelon is borne on the retained fruiting vine after the second batch of muskmelons expand; after the second batch of muskmelons are harvested, the fruited old vine is pruned away, the fertilizer and water management is strengthened to promote the expansion of the third batch of muskmelons and the regeneration and the strong growth of the randomly selected vine at the stem base of the plant, and one strong randomly selected vine is retained as a fruiting vine for fruiting again; the operation is repeated and a total of at least five batches of muskmelons are produced and harvested. The plant adjusting method for muskmelon long-season cultivation can give full play to the photosynthetic efficiency of leaves, and the one-time planting and multi-harvesting long-season cultivation suitable for muskmelons is realized.

Description

Technical field [0001] The invention belongs to the technical field of melon cultivation, and specifically relates to a plant adjustment method for long-season cultivation of melon. Background technique [0002] Melon is an important economic crop, and its cultivation has good economic benefits, especially the economic benefits of facility cultivation. Melon cultivation has become an important way to increase farmers' economic income in many areas. my country is a major producer and consumer of melons. The annual sown area of ​​melons is 590,000 hectares and the total output is 14.62 million tons, accounting for 46% and 53% of the world’s sown area and total output respectively. Therefore, the production of muskmelon in my country occupies an important position in the world (Bie Zhilong. Development status and countermeasures of my country's watermelon and muskmelon grafting seedling industry. Chinese Melon, 2011, 24(2): 68-71). As an important high-efficiency economic crop, mel...

Problems solved by technology

Its defect is that this long-season cultivation technique actually belongs to the general regenerative cultivation technique. Since the old vines are directly cut off after the melon is harvested, the growth balance between the aboveground part and the underground part of the plant is suddenly destroyed, which makes the melon root system senescence. Accelerated, its growth and absorption capacity decline, resulting in slow germination of latent adventitious buds at the base of the melon plant, weak growth of drawn adventitious vines, and some individual aging plants even die early, unable to produce adventitious vines and appear lack of vines, so regeneration The yield of melons is much lower than that of the first two batches of melons, and the quality is also poor, and only 3 to 4 harvests of one species have been achieved, so the actual promotion and application value is not great

A method for planting thick-skinned melons with multiple crops (application number 201410699575.7, application publication number CN 104350936 A) applies compound fertilizer 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. Cut off the fruiting vines, and keep a strong vine at the root for the next fruiting. Although this can partially overcome the defects of the above-mentioned regenerative cultivation technology, at least 3 batches of melons can be harvested after cultivating one crop of melons; the defect is that the plant adjustment method is still common. The "double vine" pruning method, more fruit setting at one time, greater nutrient consumption, and the use of conventional fertilizer and water management technology, melon plants and roots are prone to aging, and the growth potential of new side vines is poor, and aging is very fast. Fast, so the output and quality of the next few batches of melons are low
