Traditional soil cultivation has no problem for people who need plants and varieties. Soilless culture technology has rapidly developed soil, which means that plants grow, but in organic matter or nutrients. A carrier planting technology. With the development of soil cultivation, nutrient solution film cultivation technology has gradually developed in the southeast coastal areas, deep liquid flowing water cultivation technology has developed in the south, and model cultivation technology has developed in the north. However, these soil cultivation techniques need to use nutrients for better irrigation, which requires relevant personnel to further study and analyze the configuration and management of nutrient solution. If there is no way to master the operation mode of related nutrient solution, it is impossible to popularize large-scale soil cultivation.
Second, introduce special nutrition formula.
In the research of nutritional preparations, the traditional technology is usually based on the chemical composition of soil hydraulic fluid. This formula is usually similar to the most widely used Japanese Garden formula, Yasaki formula and Hoagland formula.
Because in greenhouse gardening, some hydroponic plants will suffer from hypoxia, people gradually found that the preparation of nutrient solution is mainly to solve the problem of root hypoxia, which has been widely used in vegetable planting. At present, Yamazaki formula is mainly based on Yamazaki tomato and Yamazaki strawberry nutrient solution. Domestic experts focused on the formula of Shaqi colorant, the original standard nutritional preparation and the concentration of calcium nitrate, which further improved the vitamin C in lettuce and avoided nitrate residue. Accumulation, etc. It is of great help to increase the yield of lettuce and is very important in water-made liquid dishes.
These three nutritional formulas are very common. Do not use it alone when using it. According to the actual situation, we should flexibly use the process of cucumber nutrient solution seedling raising to find the relevant personnel of cucumber seedling raising. Anal formula is better than oat, garden, garden and Schneider formula. In foggy days, the carotenoid protein of lettuce obtained from the original Japanese formula is higher. At the same time, with Hoagland nutrition treatment, underground lettuce is lower and its weight is relatively lower. Yamazaki nutrient solution has the lowest free radical gap after treatment, and the strength and advantages of various formulas after treatment are very obvious. Through the appropriate short board, it must be reasonable according to the actual situation, which also shows that there is some room for development and improvement in the use of nutritional preparations. Nutrients of soilless culture are usually used in these three aspects.
Thirdly, the application of nutrient solution in soil cultivation.
Hydrogen compounds can be divided into pot hydroponics and substrate hydroponics. Inorganic hydroponics, hydroponics, fog and floating water, etc. Will not produce big pests and diseases, and can also expand the breeding scope. For example, it can further improve space utilization and production potential through non-aggregation. In the process of ornamental plants, people can not only keep the environment clean, but also better enjoy the whole process of nutrient cultivation through indoor unclean technology. In addition, soil cultivation technology is also very important in many aspects such as ecological protection and sewage treatment. Hydroponics is mainly used for the cultivation of flowers. In the process of cultivation, it is necessary to strengthen the management of nutritional preparations and adjust the management methods and nutritional supply units in combination with the mechanism.
When preparing nutrient solution, be sure to give the right amount. If conditions permit, a high-precision balance can be used. When using the substrate, if there is a problem or dryness, it means that there is a problem or the problem develops slowly. Therefore, it is necessary to disinfect the substrate. In the process of cultivating nutrient solution, it is necessary to complete the work of tools through mechanized devices and automation, and strengthen irrigation devices with electricity and electricity, and monitor the dynamic growth of plants, as well as ion concentration and timely adjust pH to ensure the rapid growth of plants.
It is also necessary to pay attention to the problems in the preparation of nutrient solution, and it is best to use non-metallic containers such as ceramic glass, especially when storing mother liquor. Metal containers cannot be used to prevent some substances and iron and aluminum in nutrient solution. With the long journey and some problems of salt base, the application of soil alkali is more and more extensive.
