The most prone problem in older greenhouses is technical soil salinization(cell trays). The reason for the general cause of soil salinization is the large amount of fertilizer applied. The greenhouses are used for a long time, and it is easy to have poor heat preservation effect. In winter or early spring, it is prone to injury. Therefore, greenhouse fertilizers should contain biological fertilizers(2 gallon nursery pots supplier), humic acid fertilizers, and water-soluble fertilizers, which can alleviate soil salinization and increase soil temperature.(large plastic garden pots cheap for sale)
The use of biological fertilizers in older greenhouses is even more pronounced(plastic nursery pots manufacturers). In order to ensure that vegetables and fruits absorb enough nutrients, it is recommended that farmers' friends still use biofertilizers and compound fertilizers for rotation. Because of the high nutrient content of nitrogen, phosphorus and potassium in the old greenhouse soil(3 gallon nursery pots supplier), humic acid fertilizer can increase the utilization rate of phosphorus and potassium and some trace elements in the soil.
At present, the top of calcium deficiency is burnt(plastic nursery pots), the growth point is damaged, the fruit is small, the fruit seeds are more, and the humic acid fertilizer has synergistic effect on phosphorus and potassium. The amount of use can generally be reduced by about 1/3. The use of fully water-soluble fertilizers is small, and the utilization rate is as high as 85% or more, which can supplement the nutrients needed for crops(5 gallon nursery pots supplier), and the application of winter and biological bacterial fertilizers is a mode of fertilizer that is worth promoting.
(large plastic garden pots cheap for sale)Bio-fertilizer can release the fixed nitrogen, phosphorus and potassium in the soil and promote soil fertility(wholesale nursery pots). On the basis of increasing the application of humic acid fertilizer, the chemical fertilizer can be appropriately reduced. In the process of decomposition, organic fertilizer can continuously release carbon dioxide and improve strawberry(7 gallon nursery pots supplier). Carbon nutrition. In the case of severe zinc deficiency, the edges of the leaves have a distinct yellow or pale green jagged edge.
At present, there is still an unreasonable phenomenon in fertilization in greenhouses(plastic nursery pots wholesale). The best fertilization technology should be to ensure the increase of production and quality, but also to protect the soil environment of the greenhouse, which is conducive to sustainable high yield and stable production. Organic fertilizer can provide a variety of nutrients(14 gallon nursery pots supplier). In addition to nitrogen, phosphorus and potassium, it also contains various trace elements such as boron, molybdenum, copper and iron.
(large plastic garden pots cheap for sale)Organic fertilizers can be humified(1 gallon nursery pots supplier), and some organic compounds can be condensed and dehydrated to form more complex humus, degraded organic matter and newly synthesized humus, improve strawberry berry quality and increase sugar content. Re-application of organic fertilizer promotes soil ripening, fertility, soil fertility and water retention(15 gallon nursery pots supplier), and improves soil water, fertilizer, gas and heat conditions, and promotes the development of strawberry roots in greenhouses.
Nitrogen fertilizer can ensure the growth of plants(black plastic nursery pots). Phosphorus and potassium fertilizer can not only promote the robustness of plants, but also increase the sugar content of strawberry fruit and improve its quality. Zinc deficiency leads to narrowing of the leaves. Leafy leaves are often reddish on the surface. Boron deficiency leads to new leaves splitting(gallon plant pots wholesale), the top is burning, the secondary roots are poorly grown, the flower is not pollinated, the fruit is small, the fruit is small and deformed.
