Application area 1. Production of anti-season and horticultural products is currently being used in most countries to produce clean, quality, fresh and high-yielding vegetable products, mostly for anti-season and long-season farming. For example, in recent years, landless techniques have played an important role in the eastward and southward migration of thick-skinned melons, using devices and organic matrix-based training techniques, providing effective pathways for the cultivation of melons in the south, with significant economic benefits in early spring and autumn winter; in addition, soilless cultivation can be used on flowers, which are mostly used to plant cut flowers, herbs and woody flowers, which are large, colorful, flowery and fragrance, especially in homes and hotels. The same is true for herbal and edible culture. Improved landless crops are linked to yinglong science and technology development ltd. Energy-efficient, soil-free aquaculture in xinjiang
There are many varieties of vegetables suitable for hydroponics, and the beijing vegetable research centre has successfully tested the varieties of lettuce, daisy, mustard blue, cabbage, oil, cabbage, cabbage, mustard, kale, raisins, raisins, soybean bean, sepsis, celery, trileaf, raisin, onion, potatoes, etc. There are many varieties of vegetables suitable for hydroponics, and the beijing vegetable research centre has successfully tested the varieties of lettuce, daisy, mustard blue, cabbage, oil, cabbage, cabbage, mustard, kale, raisins, raisins, soybean bean, sepsis, celery, trileaf, raisin, onion, potatoes, etc. There are many varieties of vegetables suitable for hydroponics, and the beijing vegetable research centre has successfully tested the varieties of lettuce, daisy, mustard blue, cabbage, oil, cabbage, cabbage, mustard, kale, raisins, raisins, soybean bean, sepsis, celery, trileaf, raisin, onion, potatoes, etc. Xinjiang energy-efficient and soil-free aquaculture plants, unearthed and purified, are linked to yinglong science and technology development ltd。
(i) water conservation is based on a cucumber-free experiment conducted by the scientific research department in the autumn of the beijing region for a total of 21. 7 cubic metres of water (nutrient) for 46 days. In the case of earthbreeding, at least 5-6 times in 46 days, 50-60 cubic metres of water would be required, with a water saving rate of 50-66. 7 per cent. The effect of water conservation is clear and is one of the effective measures to develop water-saving agriculture. Landless cultivation not only saves water, but also saves fattening, which is generally considered to have a loss rate of about 50 per cent on earth-planted nutrients. In rural areas of the country, the use of fertilizers is lower, at 30-40 per cent, with more than half of the nutrients lost. The process of fertilization and plant absorption in the soil is complicated, not only by many losses, but also by different nutrients, which makes it difficult to maintain a balance between the elements in the soil solution. In soilless cultivation, the nutrients required for crops are for human formulation of nutrient fluids, not only without loss, but also with a balance between the scientific supply of nutrients, depending on the crop type and the stage of reproduction of the same crop, so that the growth of crops is robust, strong and the potential for increased production can be fully realized。
Landless cultivation is an advanced technology with unparalleled advantages in general soil-planting facilities, yet soil-free cultivation is a high-technology technology involving a variety of sciences, such as agricultural engineering, chemistry, fertilizers and crop cultivation, which are also very difficult in terms of technology, and, more importantly, because soil-free cultivation requires certain facilities and installations and requires a large supply of nutrients. The development of new types of land- and water-efficient agriculture with new technologies has become an extremely urgent subject of scientific research and industry, in view of the allocation of basic resources for agriculture in all regions of the country.

Hydraulics are plant roots that are in direct contact with nutrients and do not use matrix cultivation methods. Early hydroponics, which are immersed in the roots of plants in nutrients, can affect the breathing of the roots, resulting in root mortality in serious cases. To address this problem, british researchers in 1973 introduced hydroponics of the nutrient membrane method, which is based on a thin layer of nutrients (0. 5 - 1 cm) that circulates continuously through the root systems of the crop, ensuring continuous supply of both the water and nutrients of the crop and fresh roots. This method cultivates crops, simplifys irrigation techniques and does not have to calculate daily water requirements for crops and provides a balanced supply of nutrients. The roots are isolated from the soil, which avoids all kinds of endemic diseases and does not require soil decontamination.

(v) unrestricted areas, making full use of space-free cultivation, which completely separates crops from the soil environment and thus frees them from land constraints. Cropland is considered to be a limited, valuable and non-renewable natural resource, especially in areas and countries where it is scarce. When soilless cultivation enters the field of life, many deserts, wastelands or hard-to-cultivate areas on earth can be exploited using soilless cultivation. In addition, soilless cultivation is not subject to space constraints and can be grown using the flat roofs of urban buildings to plant flowers, expanding the area of cultivation in intangible form.
