Green vegetable production fertilization precautions

Strict control of the application time of nitrogen fertilizer The nitrate content of vegetable crops is constantly changing. Nitrogen entering the vegetable body is further converted into protein during metabolism. According to the research, with the change of nitrogen fertilizer application time, the nitrate content in vegetables has gradually decreased. After 18 days of topdressing, the nitrate content in the vegetables has met the recommended standards for green food. Therefore, the top dressing time of green vegetables should be 15 to 20 days before harvesting.
Controlling the amount of nitrogen fertilizer to ensure high yield and economic benefits of green vegetables. On the basis of applying organic fertilizer, proper application of nitrogen fertilizer is necessary, but it is necessary to control the dosage to solve the contradiction between quality and yield, yield and benefit. . At the same time, pay attention to the choice of nitrogen fertilizer varieties, the accumulation of nitrate in vegetables is reduced by the influence of sodium nitrate, ammonium nitrate, urea, ammonium chloride.
Balanced fertilization with various fertilizers can reduce the nitrate content in vegetables compared with single application of nitrogen fertilizer. Nitrogen and phosphorus combined with spraying micro-fertilizer can reduce the content of nitrate in vegetables, especially with potassium fertilizer, which can promote protein synthesis and reduce nitrate content in the body.

Prefabricated House

What is the quality of prefabricated house? Can it be used for a long time?
Many areas are now using prefabricated house. In fact, this type of house is to prepare the internal structure of the house in advance, and then complete the assembly of the house. In this way, the construction type, area, interior decoration, etc. of the house can be completed at one time, the construction efficiency is faster, and the cost is relatively favorable. But how is the quality of such housing? Can it be used for a long time?

Is the quality of prefab houses guaranteed?
Most people do not have a deep understanding of prefabricated houses, and always think that the quality of such houses is average, and problems may even occur in a short time. The Prefabricated K House and Folding Container House produced by Henan Jinming are checked at all levels from the procurement of raw materials to the later construction process to ensure that the construction site is constructed by professional workers, and the regular construction party will also provide us with long-term after-sales service. So you don't have to worry about its quality, it can be guaranteed for 30 years of long-term use.

How long does it take to build a prefab house?
The reason why such houses are being used in many areas is mainly because their production cycle is relatively short. Because prefabricated houses are all produced by workers on the assembly line, the production efficiency is high, and the quality is guaranteed, so the production cycle is relatively short. Moreover, formal businesses will conduct strict quality inspections on them, so even if they are mass-produced, they can guarantee to provide high-quality residential houses in a short period of time.

Is Prefab Home Construction Fast?
After the prefabricated house is finished, it also needs to be constructed on site, because the main body has been fabricated, and its construction has standardized requirements. Compared with traditional house construction, its construction efficiency is high, and the construction can be completed in a short time. Especially for some construction sites, the construction efficiency of such houses is high, and workers can live in high-quality houses immediately.
In fact, as long as you can cooperate with regular merchants, you can also guarantee the purchase of suitable prefabricated houses. Moreover, the quality of such houses is guaranteed, the cost is favorable, and the cost-effective prefabricated houses are also very worth choosing.
