For the improper fertilization, as long as the scientific fertilization method is mastered, the salt damage of vegetables can be avoided(propagation tray). At the same time, if the secondary salinization is harmful to the vegetables, it can cause the entire plant to die in severe cases, and the whole shed will fail(128 cell propagation trays wholesale). It can directly spray water to the roots of plants through pipes and micro-drip holes, which reduces the loss of water and facilitates the uniform application of fertilizer with water.

After many years of cultivating vegetables in greenhouses(plug trays), due to excessive irrigation, poor water quality, large application of chemical fertilizers, and long-term application of human feces and urine, the soil salt content is likely to increase, manifested as soil salinization, that is, secondary salting. Loquat vegetables usually appear as short plants, and the leaves are usually pale, and the waxy leaf margins are rolled(162 cell propagation trays wholesale). In the later period, the yield is low and the quality is reduced.
(cheap thermoformed pots manufacturers indonesia)The root system is shallow, the lateral roots are few, and the root hairs are thin and rusty(seed starting trays). In severe cases, the plants die and the whole shed loses harvest. Vegetables are grown in sheds and other covering conditions. The temperature in the shed is high and the amount of soil water evaporation is large(200 cell propagation trays wholesale), so that the salts in the lower soil rise to the surface of the soil by capillary action, causing salt to accumulate on the soil surface.
What to do if salt damage occurs in vegetable fields? Vegetable salt damage occurs in greenhouse cultivation and inappropriate fertilization methods(square grow pots). Firstly, an appropriate amount of irrigation should be performed according to the water demand of the greenhouse vegetables at each growth stage(112 cell propagation trays wholesale). Secondly, the water quality of the irrigation water should be tested, and water with a large salt content cannot be used. Extend the useful life of soil in the greenhouse.
Due to the addition of organic and biological fertilizers, for the greenhouse soil(nursery plant pots), white salt spots and salt flowers will appear on the surface of the saline soil, and even copper blue or tan salt spots will appear. When the soil salinization in the greenhouse is severe, the number of stubble vegetables in the greenhouse is high, the yield is high, and the amount of fertilization is large(288 cell propagation trays wholesale). In addition, the desalting effect of corn is also good.(cheap thermoformed pots manufacturers indonesia)
The soil with heavy texture must be mixed with sand for improvement(plastic plant trays wholesale). The radon caused a large amount of unabsorbed chemical fertilizer to accumulate in the soil, resulting in an increase in salt concentration. Cultivation measures such as shallow ploughing in the greenhouse and pouring fertilizer on the topsoil have exacerbated the concentration of salt in the surface layer(20 cell propagation trays wholesale). According to the survey, the soils of greenhouses planted for more than 3 years all suffered from different levels of salt damage.
Formulated fertilization and supply on demand can significantly reduce the residual accumulation of salt in the soil(wholesale nursery pots). It is best to popularize the micro-drip irrigation technology when conditional irrigation. At the same time, a large amount of organic fertilizer should be added to increase the soil organic matter content(24 cell propagation trays wholesale), improve the soil aggregate structure, improve soil fertilizer and water retention performance, and then appropriately reduce the amount of irrigation.
(cheap thermoformed pots manufacturers indonesia)Organic fertilizer is mainly used, supplemented by chemical fertilizers, and nitrogen, phosphorus, and potassium are applied in proportion to the principle of fertilizer application for formula fertilization(seed starter trays); in addition, the type of fertilizer and method should be properly selected, and fertilizers without negative ingredients should be applied as much as possible(plant start trays wholesale), such as Urea, potassium nitrate, calcium phosphate, diammonium phosphate, etc.
