Special base fertilizer for first year of dense planting nectarine culture

Abstract

The invention discloses a special base fertilizer for the first year of dense planting nectarine culture, and relates to the technical field of a fertilizer. The base fertilizer is prepared from the following raw materials in parts by weight: 80 to 100 parts of water-absorbent coated urea, 40 to 50 parts of ammonium chloride, 30 to 40 parts of ammonium sulfate, 60 to 80 parts of diammonium phosphate, 70 to 80 parts of calcium magnesium phosphate fertilizers, 45 to 55 parts of potassium chloride, 30 to 40 parts of white mica powder, 180 to 200 parts of fermented organic fertilizers, 4 to 7 parts of humic acid, 1 to 3 parts of cigarette slag, 3 to 5 parts of borax, 3 to 5 parts of fishbone dust, 1 to 3 parts of ironic citrate, 1 to 3 parts of amino acid chelated manganese, 1 to 3 parts of amino acid chelated zinc and 1 to 2 parts of copper sulphate. The prepared base materials can well meet the required nutrient characteristics of the nectarine culture at each stage; the growth is promoted; the fertilizer utilization rate is high; good basis is laid for the high yield of the nectarine in the later stage; the contained water-absorbent coated urea also has the water preservation and slow release performance; the retaining of the water in the seedling root system region can be realized; the first year culture survival rate is improved; the growth is promoted; the fertilizer utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special base fertilizer for the first year of close-planted nectarine cultivation. Background technique [0002] Nectarine is a variant of common peach, with high nutritional value, fragrant, sweet and crisp. Not greasy. [0003] In nectarine cultivation, except species, water and fertilizer are important factors affecting yield and quality. At present, there is an unreasonable ratio of the ingredients in common fertilizers for nectarines. There is no effective balance between various effective nutrients, and there is a lack of special fertilizer varieties suitable for nectarines. This makes the level of scientific fertilization of nectarines not high, resulting in high yields. not tall. In addition, there is also the problem of low fertilizer utilization rate, which will cause adverse effects on the environment, easily cause soil compaction, soil hardening, and poor wat...

Problems solved by technology

At present, there is an unreasonable ratio of the ingredients in the common fertilizer for nectarines, the effective balance of various effective nutrients is not reached, and there is a lack of special fertilizer varieties suitable for nectarines, which makes the level of scientific fertilization of nectarines not high, resulting in high yields. not tall

In addition, there is also the problem of low fertilizer utilization rate, which will cause adverse effects on the environment, easily cause soil compaction, soil hardening, and poor water and fertilizer retention.

In particular, the application of water and fertilizer in the first year of densely planted nectarines has a direct relationship to the later yield, but there are few studies on it at present
