Tomato soilless culture is usually carried out in greenhouse, which can be used all year round. Tomato soilless culture in solar greenhouse can determine the rotation arrangement according to the performance of greenhouse, and generally it is mainly produced in winter and spring.
Bitter gourd is an annual climbing herb in Cucurbitaceae. Its stems, branches, petioles and pedicels are covered with soft hairs. The conditions required for armpit hair cultivation are not strict, with strong growth potential, strong fruit-setting ability and long harvest period, which is suitable for soilless culture.
In recent years, the planting area of eggplant in solar greenhouse and greenhouse has been expanding, but due to continuous cropping, diseases, especially soil diseases, are serious. This problem can be overcome by soilless culture, which has gradually become popular in recent years.
Continuous cropping of ginger with traditional planting methods can not remove the residual nematodes and strong blast bacteria in the soil, and it is easy to be infected with strong blast. Once infected with strong rice blast, large plants will wither and die. Soilless culture can solve this problem.
Cucumber is often harmed by pests and diseases in production, but soilless culture has the characteristics of avoiding soil-borne pests and diseases and continuous cropping obstacles, reducing pesticide consumption, improving crop yield and quality, saving fat and not being limited by land fertility.
In soilless culture, all kinds of nutrients needed by crops are artificially prepared and used as nutrient solution, which can provide nutrients scientifically according to different breeding stages of crops, such as crop types, so crops grow vigorously and have a strong growth momentum.
Soilless culture uses inorganic fertilizers, and soil planting produces organic fertilizers, which decompose and ferment, pollute the environment, produce eggs of many pests and endanger crops. So soilless culture does not have these problems.
Soilless culture does not need Chongqing, digging, hoeing and so on. , reducing the hard work. Watering and topdressing can be solved at the same time, and the infusion system will supply it regularly and quantitatively, which will not cause waste, and the management is very convenient and the labor intensity is greatly reduced.
In vegetable field planting management, reasonable rotation and avoiding continuous cropping for many years are one of the important measures to prevent the serious occurrence and spread of diseases. Soilless culture, especially hydroponics, has fundamentally solved this problem.
Soilless culture can completely isolate crops from soil environment and is not limited by soil quality and water conservancy conditions. Many deserts, wasteland or areas difficult to cultivate on the earth are used as soilless culture methods. 6. Make full use of space: Soilless culture can get rid of the restrictions of land and space. Using flat roof vegetables in urban buildings to grow flowers can actually expand the planting area and produce according to people's will.
