Vine hanging cultivation pruning method for greenhouse muskmelons

Abstract

A vine hanging cultivation pruning method for greenhouse muskmelons comprises the steps of muskmelon pruning at the seedling stage: pinching is performed when 3 to 4 leaves grow on a mother vine, a strong son vine is left on the lower portion of the 3 to 4 leaves for hanging, and the other son vines are removed from the root; muskmelon seedling pruning at the vine extension stage: pinching is performed when the 3 to 4 leaves of the mother vine and leaves growing on the son vine reach 12 to 13, 5 to 9 leaves are left for grand vines, 10 to 13 leaves are left, and the other new vines are removed; muskmelon seedling pruning at the fruit setting stage: a well-developed female flower is selected between the 5 to 9 leaves of the son vine for fruit setting, only 1 good-shaped muskmelon is left on each son vine, and 2 to 3 leaves are reserved on the grand vines for pinching after fruits are set; fruits on the grand vines are reserved if fruits are not born on the son vine, and 3 to 4 leaves after fruits are born on the grand vines for pinching.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for growing and pruning muskmelons in greenhouses. Background technique [0002] Pruning and topping is the key technology for the success or failure of melon cultivation, because the main vines of melon grow weakly, but the side vines grow vigorously, and thin-skinned melons generally bear fruit from sub-vines and grandchildren. In order to regulate the growth of melon stems and vines, production Techniques such as topping, pruning, and branching are often used to control the vegetative growth of stems and vines, so as to promote early fruiting and early maturity. The melon farmers can adopt the following methods for pruning: [0003] Single vine pruning, main vine not topping: select the sub-vines with more than 4-5 knots in the middle to form melons, leave 2-3 leaves in front of the melons to pick the sub-vines, and the upper sub-vines can grow freely accor...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned pruning technology has the following problems: single vine pruning, main vines are not topped, and the sub-vines are allowed to produce melons, and the fruit growth is allowed to be irregular, which affects planting, fertilization and management, increases the growth time and fruit time to market, and the efficiency is too slow. Affect the next crop rotation; double vine pruning: topping is too late, the growth of the twin vines requires a lot of nutrients and only one melon can be left in the two vines, the yield is too low, and the remaining fruits have to wait for the grandson vines to grow to ensure the retention of melons, fruit development and production speed Slow, can't advance the time to market, can't seize the market early
