Compared with soil culture, facility soilless culture has the following advantages and disadvantages:

First, it is not limited by land and has a wide scope of application.

Watermelon can be cultivated without soil as long as there is a greenhouse or shed and there is water.

Second, overcome the obstacles of soil continuous cropping.

Watermelon is the most taboo for continuous cropping. Generally, it takes more than five years of crop rotation, which cannot be done in greenhouse or fixed greenhouse. Soilless culture can be continuously planted only by cleaning the cultivation bed or changing the substrate.

Third, improve the quality of watermelon.

Soilless cultivation of watermelon can produce pollution-free watermelon because of its proper nutrition, fine vines, fine fruits and good appearance quality, and no or little use of pesticides.

Fourth, the labor intensity is not great, suitable for all ages.

Because it is semi-automatic, the labor intensity is reduced.

Its disadvantage is large one-time investment. Such as building glass greenhouses, side-building greenhouses and supporting facilities for water supply and drainage, with high investment; Even the one-time investment in plastic greenhouse production, ventilation and pest control equipment, irrigation and drainage facilities and aquaculture pond construction is also very large; In daily operation, although the labor intensity is not great, it takes a lot of man-hours. At present, nutrient solution has high cost and large water consumption. The above factors limit the popularization of soilless culture.
