Embodiment 1

[0014] Embodiment 1: topdressing fertilization before a kind of walnut tree bud, the weight percent composition of each active ingredient of it is: nitrogen 15%, phosphorus 3%, potassium 2%, calcium 1%, molybdenum 0.1%, manganese 0.1%, copper 0.1% %, boron 0.1%, humic acid 5%. Select the corresponding raw materials according to various active ingredient elements: urea, monoammonium phosphate, potassium sulfate, EDTA chelated calcium fertilizer, EDTA chelated copper fertilizer, EDTA chelated manganese fertilizer, ammonium molybdate, boric acid, biochemical fulvic acid.

[0015] The preparation method is as follows: Weigh the raw materials according to the weight percentage of each active ingredient in the topdressing fertilization of walnut trees before budding, and reserve; add 2 times the weight of the raw materials in sequence according to the solubility and volatility from small to large, and the temperature is 20-40°C In the water, stirring and dissolving, filter and slag ...

Embodiment 2

[0017] Embodiment 2: topdressing fertilization before a kind of walnut tree bud, the percentage by weight of its each active ingredient is: nitrogen 20%, phosphorus 4%, potassium 4%, calcium 1.2%, copper 0.15%, manganese 0.15%, molybdenum 0.15% %, boron 0.15%, humic acid 7%. Select the corresponding raw materials according to various active ingredients: ammonium nitrate, diammonium phosphate, potassium chloride, EDTA chelated calcium fertilizer, EDTA chelated copper fertilizer, EDTA chelated manganese fertilizer, sodium molybdate, boric acid, biochemical fulvic acid. Its preparation method is the same as that of Example 1. When applying, 10 kilograms of finished fertilizer per mu is slowly applied to the root soil by drip irrigation or sprinkler irrigation before the walnut tree germinates.

[0018] Apply the above-mentioned finished fertilizer to the walnut trees: the walnut leaves are produced 3 days in advance, the leaves are dark green, the flower buds are full, the flower...

Embodiment 3

[0019] Embodiment 3: topdressing fertilization before a kind of walnut tree bud, the percentage by weight of its each active ingredient is: nitrogen 25%, phosphorus 4%, potassium 6%, calcium 1.5%, molybdenum 0.2%, manganese 0.2%, copper 0.2% %, boron 0.3%, humic acid 10%. Select the corresponding raw materials according to various active ingredients: ammonium nitrate, monoammonium phosphate, potassium sulfate, EDTA chelated calcium fertilizer, EDTA chelated copper fertilizer, EDTA chelated manganese fertilizer, sodium molybdate, borax, humic acid. The preparation method is the same as that in Example 1. When applying, 35 kg of finished fertilizer per mu is slowly applied to the root soil by drip irrigation or sprinkler irrigation before the walnut trees germinate.

[0020] Apply the above-mentioned finished fertilizer to the walnut trees: the walnut leaves are produced 5 days in advance, the sprouts are pulled out ahead of time, the flower buds are full, and the leaf spot dise...

Abstract

The invention provides a pre-emergence topdressing fertilizer for a walnut tree and a preparation method thereof, belonging to the technical field of fertilizers. Effective components of the fertilizer comprise, by weight, 15 to 27% of nitrogen, 3 to 6% of phosphorus, 2 to 6% of potassium, 1 to 1.5% of calcium, 0.1 to 0.3% of molybdenum, 0.1 to 0.3% of manganese, 0.1 to 0.3% of copper, 0.1 to 0.3% of boron and 5 to 10% of humic acid. The pre-emergence topdressing fertilizer prepared in the invention can timely meet demands for nutrients needed in the physiological activities of germination and blossoming of the walnut tree, enables the walnut tree to rapidly germinate in early spring, strengthens respiration intensity, accelerates metabolism and cell division and allows the physiological activities of blossoming, embryo development, foliation, sprouting and the like to be smoothly carried out. When the fertilizer is cooperatively used with a micro-irrigation system, a high absorption and utilization rate and timely substantial fertilizer efficiency are realized. The preparation method has a simple process and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a pre-emergent topdressing of walnut trees and a preparation method thereof. Background technique [0002] Over the years, my country's agricultural high yield mainly depends on the application of a large amount of chemical fertilizers, the overweight of many soil nutrients and the lack of trace elements, resulting in soil salinization and compaction and deficiencies. Such as zinc deficiency, the leaves are small and yellow, curled, and in severe cases, the leaves of the whole tree are small and curled, and the tops of the branches die; manganese deficiency, the leaves lose chlorosis, and the veins become light green, withered spots on the mesophyll and leaf margins, prone to premature Falling; boron deficiency, branches withered downwards, brown turbid spots appear between leaf veins, leaflets are easy to deform, and young fruits are easy to fall off; copper deficiency, ofte...
