A kind of efficient and labor-saving cultivation method of small watermelon

Abstract

The invention discloses a small-scale high-efficiency and labor-saving watermelon cultivation method which comprises the following steps: making planting ridges; laying mulching films and dropper zones; planting watermelon seedlings; building an arched shed; forming holes in shed plastic films; performing field management. The arched shed support is made by adopting glass fiber pipes, only a layerof shed films is used, one-time permanent ventilation is performed in a manner of forming holes in the shed films at the later stage, the investment is less, and the operation is simple. According tothe method disclosed by the invention, small watermelons are basically located in a stable growth environment in the early growth period, the condition that the plant growth is influenced due to temperature fluctuation caused by ventilation in the general arched shed cultivation manner is avoided, the watermelons grow in a rainproof environment at the later stage, the plants are healthy and strong, the growth speed is high, the diseases and cracking fruits are decreased, the watermelons can appear in the market in advance, the commodity nature of the watermelons is excellent, and the benefitsare high. The watermelons are covered by green plastic films, the effects of inhibiting weeds and maintaining the temperature and humidity can be achieved, and the phenomenon that leaf sunburn is caused by strong light in summer can be avoided.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a high-efficiency and labor-saving cultivation method for small watermelons. Background technique [0002] The traditional watermelon cultivation method is generally open-ground climbing cultivation. The vines and fruits are all over the ground. Because the melons and fruits mature on the open ground, the coloring of the fruit surface is uneven, it is easy to be infected with diseases, and the commodity is poor. If the water management is not proper, it is easy to crack the fruit. . Cultivating watermelons in protected areas can bring watermelons to the market earlier and significantly improve the economic benefits of growers. Therefore, in recent years, the area of ​​watermelons cultivated in protected areas in my country has increased year by year. Cultivating watermelons in arched sheds is a relatively common watermelon cultivation mode in protected areas. It is charac...

Problems solved by technology

[0004] The first type is greenhouse hanging vine cultivation, every 667m 2 The number of cultivated plants can reach 1200, the yield is high, and the surface of the watermelon is evenly colored, and the commodity is good; however, due to the need to build sheds and hang vines, the production cost increases, and the ventilation management needs to be carried out according to the temperature situation, which is laborious and labor-intensive. Large-scale promotion application is limited

[0005] The second type is mulching and climbing cultivation in greenhouses, every 667m 2 The number of cultivated plants can reach 600-800. Compared with greenhouse hanging vine cultivation, this method saves labor, but the yield is low. In the early stage, ventilation management should be carried out frequently according to the temperature situation, which is laborious and laborious

[0006] The third type is the traditional small shed cultivation, which generally adopts the double-film mode, that is, the "plastic film + shed" mode, and every 667m 2 Cultivate 600-800 plants, seal the surrounding area with soil after covering, remove the shed film and arch frame at the later stage of growth, and grow watermelons in the open field. This method saves construction costs compared with greenhouses, but the watermelon growth period also needs to be ventilated according to temperature conditions. Improper water management in the later stage, the watermelon is easy to crack, and the watermelon grows in the open field, and the appearance of the watermelon is poor.

[0007] Arched shed cultivation of watermelon is generally used in early spring, when there will be strong winds at any time in this season. The above three methods must be artificially ventilated in the early stage of growth. The growth of watermelon is seriously affected; during the venting process, we must also pay attention to the position, size and distance of the air outlet, and at the same time, we need to grasp the time of venting, which requires a skilled process and high technical requirements. influences
