According to the test, the annual seedling seedlings of Pinus sylvestris var(3.5inch square nursery pots). mongolica cultivated in sandy land, the seedlings applied with mycorrhizal fungi (pine forest soil) are 32% higher than the control area on average, and the seedling mortality rate is reduced by 26.7%-40% compared with the control area(deep cell plug trays), which promotes the conversion of some insoluble inorganic and organic compounds into soluble nutrients.

Mycorrhizal fungus seedlings with mycorrhizal species are sensitive to mycorrhizal fungi(4.5inch square nursery pots). For example, Pinus tabulaeformis seedlings and larch seedlings growing on soil lacking mycorrhizal fungi not only grow poorly, but the leaves all show light color, such as inoculation with mycorrhizal fungi grow well. In warm and rainy areas, organic matter decomposes quickly and organic nutrients are easily lost(large plastic planters uk). Alkaline soils should use acidic fertilizers.
(cheapest plastic 5 gallon planter manufacturers canada)Because mycorrhiza can replace the root hairs of seedlings in the soil to absorb phosphorus(4.5inch deep square pots), iron and other nutrients and water, and can prevent phosphorus from being excreted from the roots of the seedlings: the mycelium densely spread in the soil fill can stretch farther away from the root In places(plant pot suppliers), net-shaped auxiliary roots are formed, which expands the absorption area of seedlings; mycorrhizal fungi can also secrete organic acids.
Nitrogen fertilizers use ammonia nitrogen fertilizers such as sulfuric acid or ammonium chloride(seedling trays wholesale). The method of inoculation is to mix seed with fungus or to make fungus soil made from fungus and withdraw it to the seedling bed, and then mix it with the 5 cm thick soil layer on the bed(16.5cm plastic grow pots). Ammonia-fixing bacteria fertilizer is used for seed dressing as base fertilizer or for composting. In alkaline soil, phosphorus is easily fixed and not easily absorbed by seedlings.
In the case of aseptics, forest soil with mycorrhizal fungi can be sprinkled into the seeding ditch, and small seeds can be sprinkled on the seedbed first, mixed with the bed soil and sown(seed starting trays supplier). The selection of fertilizers must conform to the soil filling conditions, climatic conditions and tree species characteristics of the seedling land(wholesale plastic garden pots). When choosing fertilizers, choose water-soluble phosphate fertilizers, such as superphosphate or ammonium phosphate.(cheapest plastic 5 gallon planter manufacturers canada)
Organic fertilizers such as de-fertilization, composting and green manure are the best fertilizers to maintain soil fertility(seed propagation trays). In order to improve the soil and increase soil fertility, a large amount of organic fertilizer must be applied. Loose or sticky soil should be dominated by organic fertilizers(plastic plant pots wholesale). If chemical fertilizers are the mainstay, the physical properties of the soil will deteriorate over time and the mounds will harden and harden.
(cheapest plastic 5 gallon planter manufacturers canada)The basic fertilizer should be based on organic fertilizer, and mixed with mineral phosphate fertilizer(plastic cell trays supplier). Nitrogen fertilizer can also be used as a base fertilizer, but use nitrogen as a base fertilizer. Do not use nitrate nitrogen fertilizer such as acid, press sulfuric acid and urea(19cm plastic grow pots). In areas where there is heavy rainfall in winter or early spring and fertilizer leaching is prone, ammonia should not be used as a base fertilizer, which can be absorbed by seedlings.
Liu fertilizer can also be used as base fertilizer with other fertilizers if necessary(plastic potting pots). Top dressing should be based on quick-acting inorganic fertilizers, such as nitrogen and potassium fertilizers. Phosphate fertilizers are generally not used as topdressing soil. After the death of mycorrhizal fungi, the mycelium itself is mineralized and exists as free nitrogen-containing compounds in the soil(succulent plug trays), which can be used by seedlings, so the seedlings grow better.
