Greenhouse vegetables are generally divided into four main categories: leaf-based vegetables; flower-looking vegetables; fruit-looking vegetables; and root-forming vegetables, all of which are suitable for matrix cultivation。
First, the leaves are short- and fast-growing over a long period of time, with soilless seedlings lasting 15 to 30 days and 20 to 40 days after planting. Leafseeds are grown in smaller strains, ranging from hydroponic to base culture, and gardening combines two cultures, mainly in the form of plumbing, poles and walls。
Secondly, flower vegetables have a long-term growth cycle, with young seedlings growing for 25 to 30 days in conditions of soilless cultivation, and can bloom 60 to 70 days after planting and reach the aesthetic period. Planted vegetables, because of their large size, are hard to achieve under hydroponic conditions, and under plant conditions they can produce seedlings and sights. In the viewing of flowers, there is also a greater use of ducts, pellets, poles and wally forms of soilless cultivation。
Thirdly, the fruit harvest is 30-50 days in regular field planting, and if soilless cultivation is carried out in greenhouses, the fruit harvest can be increased by one to two months, especially for eggplant vegetables. Vegetables are tall, so when they are unearthed, they are fixed by rope, and when they are bred by special wood, the roots of the plants are fixed. At present, in the gardening of ornamental fruits and vegetables, spraying and asbestos cultivation techniques are used mainly in combination with pipeline, pelvis and stereoculture。
Iv. Vegetables, which generally use air-based baskets, can be cut half-basketed when their troughs expand to the point of appreciation, so that the troughs can be shown for reward. Air potatoes, air potatoes, etc。
