Ground growing and vertical frame type combined cultivation method for watermelons

Abstract

The invention discloses a ground growing and vertical frame type combined cultivation method for watermelons, and belongs to the technical field of agricultural planting. The method comprises the following steps: step 1, constructing a greenhouse; step 2, performing soil preparation and fertilization; step 3, raising seedlings; step 4, determining planting spacing, and performing field planting ina suitable period; step 5, constructing a quadripod, performing pruning and vine guiding, performing pollination, and performing watermelon reservation; step 6, performing fertilizer and water management; step 7, preventing and controlling pests and diseases; and step 8, performing timely harvesting. The method provided by the invention utilizes a greenhouse frame to keep warm and take shelter from rain, and avoids the problem that pollination is affected in the flowering and fruit-setting periods of the watermelons because of overcast and rainy low-temperature weather, so that normal pollination and fruit setting can be performed on the watermelons; the ground growing and vertical frame type combined cultivation is used, watermelon vines are guided onto the greenhouse frame in a verticalframe type; after the watermelons set fruits, the watermelons can be put on the ground without the need of hanging the watermelons, so that leaf areas of photosynthesis of the watermelons are increased in a limited space, and growth and expansion after the watermelons set the fruits are facilitated; and meanwhile, the planting density of the watermelons is increased, and the yield of the watermelons, the use ratio of land and economic benefits of watermelon farmers are increased.

Description

technical field [0001] The invention relates to a method for combined cultivation of watermelons by crawling and standing, and belongs to the technical field of agricultural planting. Background technique [0002] Watermelon is a summer fruit with sweet flesh, which cools down the temperature and relieves heat. It is cultivated in various parts of China, and its planting area is the largest in the world. In recent years, farmers have achieved high economic benefits by planting watermelons. Watermelon planting methods generally adopt two cultivation modes: hanging vines in greenhouses and crawling in the open field. Hanging vines in greenhouses is mainly used to grow small melons (small melons refer to a single melon weighing less than 5kg), and the planting density is plant × row spacing = 60 ×80cm, every 667m 2 Plant 1300-1500 plants, pruning with double or triple vines, and hanging vines or scaffolding vines for vine introduction. When the watermelon grows to 450-500g, p...

AI Technical Summary

Problems solved by technology

If the planting density is too high, there is not enough space to stretch out, the leaves overlap each other, and the photosynthetic leaf area is small, which is not conducive to fruit expansion

If the large watermelon is in the form of hanging melon after fruit setting, when the watermelon enters the swelling period, the growth of the watermelon will be inhibited, and the weight of a single melon can only be 2.5-5kg, resulting in a decrease in yield
