Description
Technical field
The present invention relates to a kind of dedicated fertilizer that is suitable for spraying and seeding afforesting, be mainly used in field of forestry, as Revegetation and greening and the soil conservation of bare side sloping.
Background technology
In the China based on agricultural, the effect of fertilizer in agriculture production is most important, but a large amount of uses of fertilizer have also brought a series of society and environmental problem.Fertilizer uses single, and nutrient is unbalanced, and usage quantity is big but utilization ratio is low, has also increased the risk of environmental pollution when causing soil fertility to descend.According to the demand in market, new-type fertilizer such as microbial fertilizer, slowly/controlled releasing fertilizer, novel organic fertilizer material have dropped into research.At present, the research direction of fertilizer mainly is to be applied to agricultural productions such as crop, fruit tree, tealeaves, vegetables, with short production cycle, mostly be the high instantly-soluble fertilizer of obvious effect of increasing production and fertilizer efficiency, for the long forest of growth cycle, can not guarantee the nutrient supply of later stage plant, the fertilizer in the existing market is difficult to satisfy the needs of plant in the spraying and seeding afforesting.
The high order granule ecological property of Revegetation and the environment " protection " technology is mainly used in Revegetation and greening and the water and soil conservation of bare side sloping.Plant growth environment is abominable land occupation conditions such as soil layer is thin, soil property is poor, soil nutrient content is few, must contain abundance and abundant nutrient in the substratum.But when using, quick-acting chemical fertilizer such as common fertilizer or high-effective chemical fertilizer, running off causes initial stage herbaceous plant ramp soon and easily, and meeting is the unfavorable factor to competing property of xylophyta at aspects such as illumination and nutrition, is unfavorable for the formation of woody plant community, xylium.The data record, the fertilizer of low nitrogen, phosphorus acid content height and slow-releasing is conducive to the formation of woody plant community, xylium's structure.Different with forest seedling nursing with conventional garden plants application mode, use in the spraying and seeding afforesting be with plant with directly spray after materials such as substratum starting material mix with domatic on, soil layer is thinner, requires fertilizer not cause damage to seed and growth of seedlings.
Summary of the invention
This purpose is to provide a kind of spraying and seeding afforesting dedicated fertilizer that is suitable for, to satisfy the needs of group's plant-growth.This fertilizer is the organic and inorganic fertilizer material, can promote growth and development of plant effectively, strengthens the resistance of plant, improves the soil, and improves fertilizer utilization ratio, solves the problem of fertilizer efficiency time length simultaneously.
For addressing the above problem, the technical solution used in the present invention is: this spraying and seeding afforesting is special-purpose fertile, is mixed by mineral manure and the humic acids of nitrogenous phosphorus potassium, and its component (mass fraction) be N4.5-7, effective P
2O
59-20, effectively potassium (K
2O) 4.5-6, the former powder 20-25 of humic acids.
Nitrogen among the present invention is diammonium phosphate or ammonium magnesium phosphate; Phosphorus is fused(calcium magnesium)phosphate, or double superhosphate; Potassium is vitriolate of tartar or sulphate of potash magnesia; The former powder of humic acids (organic greater than 85%, humic acids 〉=70%).Wherein in the mixed fertilizer, nitrogen phosphorus potassium best in quality proportioning is 1:3:1.Execute nitrogen and too much can suppress the formation of root nodule, thereby influence the nitrogen fixation of plant.The low high fertilizer of nitrogen phosphoric acid ratio is conducive to promote fabaceous nitrogen fixation.Simultaneously, fused(calcium magnesium)phosphate is the solubility in citric acid slow release fertilizer, the required nutrient of supply plant that can be long-term.
The invention has the advantages that:
1. this fertilizer does not contain the objectionable impurities that seed germination is had inhibition and injury effect, can do seed manure and use, and is little to seedling and root system damage, can make base manure yet and use.
2. this fertilizer is according to the characteristics of tree seed and the requirement of growth and development of plants, and the nitrogen phosphoris and potassium fertilizer ratio proportioning is suitable, is conducive to the formation of woody plant community, xylium's effect.
3. this fertilizer has added humic acids, on the basis that promotes plant-growth, can improve the physico-chemical property of soil effectively, promotes plant to absorption and the utilization of nutritive element, is conducive to the growth of plant.
Embodiment
The invention will be further described below in conjunction with real case:
In the spraying and seeding afforesting process of somewhere, adopt fertilizer of the present invention and GB composite fertilizer to compare test respectively.A is domatic to be that (K-15), B is domatic to be fertilizer of the present invention for N-15, P-15 in GB composite fertilizer.
B group fertilizer ratio is as follows: diammonium phosphate (N/P, 18/46) 30 mass parts, fused(calcium magnesium)phosphate (P, 12%) 20 mass parts, vitriolate of tartar (effectively potassium 〉=50%) 10 mass parts, humic acids 20 mass parts.
When carrying out domatic spraying and seeding afforesting, respectively A is organized the fertilizer 8kg of GB composite fertilizer 10kg and B group, apply the bottom hypothallus, the top layer Seed Layer is not added fertilizer, and plants configuration is locust tree, false indigo, Stem or leaf of Shrub Lespedeza, yellow wood, the twigs of the chaste tree, rye grass, Festuca Arundinacea.Respectively the growing state of the unit surface plant of nursery stock and nursery stock amount etc. are carried out statistical study after 3 months.
By above data as can be seen, the herbal height of A group is greater than the B group, but the total amount of B group xylophyta is far longer than the A group.Common GB nitrogen-phosphorus-potassium compound fertilizer is quick-acting high nitrogen fertilizer material, can cause initial stage herbaceous plant over growth, causes the growth of xylophyta to be restricted, thereby influences the formation of woody plant community, xylium.Fertilizer nitrogen content of the present invention is less relatively, and fertilizer efficiency is long and phosphorus acid content is bigger, when suppressing the herbaceous plant primary growth, can effectively promote the growth of xylophyta.
Humic acids among the present invention be by plant and animal residues through weathering for many years, microbiological degradation, and a series of conversion process such as earth transition and a kind of organic substance of accumulating.Both can use separately, can mix use with other fertilizer again.Except the nutritive ingredient that itself has, humic acids is trace elements such as k adsorption, ammonium, magnesium, iron, manganese, copper, zinc in a large number, effectively improve fertilizer utilization ratio, can supply nutrient continuously for plant for a long time, suit to use the long plant of growth cycle.Humic acids can effectively improve soil physico-chemical property, increases the microflora in the soil.
The application process of dedicated fertilizer of the present invention: when carrying out spraying and seeding afforesting, the degree of depth of bottom fertilising needs 2-3cm place under Seed Layer, seed manure can not directly contact with seed in use, so Seed Layer can not add fertilizer when sowing grass seeds by duster, and rate of fertilizer application is between 1 square metre of 200g-300g.
