Special fertilizer for densely-planted nectarine seedlings

Abstract

The invention relates to the technical field of fertilizers and discloses a special fertilizer for densely-planted nectarine seedlings. The special fertilizer is prepared from, by weight, 90-110 partsof water-retaining coated urea, 35-45 parts of ammonium nitrate, 50-60 parts of monoammonium phosphate, 7-15 parts of calcium superphosphate, 40-50 parts of monopotassium phosphate, 5-10 parts of potassium sulfate, 20-30 parts of plant ash, 140-160 parts of fermented organic fertilizers, 3-6 parts of humic acids, 2-5 parts of borax, 7-15 parts of broussonetia leaf powder, 3-7 parts of amino acidchelated trace elements, 4-8 parts of bagasse and 2-5 parts of kelp residues. The special fertilizer for the densely-planted nectarine seedlings contains various organic and inorganic nutrients; by reasonable ratios of nutrients such as nitrogen, phosphorus and potassium in the fertilizer and increase of ratios of the slow-release water-retaining coated urea and the slow-acting fermented organic fertilizers in the fertilizer, vigorous growth of nectarine trees can be promoted, excessive growth of branches of the nectarine trees can be avoided, tree crown control is realized, and high yield isbenefited; in addition, the special fertilizer is lasting in efficiency and can be used as a base fertilizer or additional fertilizer for the nectarine seedlings, soil improvement can be realized, andaccordingly nectarine growth is promoted, and yield increase and fruit quality improvement are realized.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for densely planted nectarine saplings. Background technique [0002] Nectarine is a variant of common peach, with high nutritional value, fragrant, sweet and crisp. Not greasy. [0003] In nectarine cultivation, besides the variety, 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 water and fertilizer r...

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 cultivation of nectarine young trees (2-4 years) has a direct relationship to the later yield, but there are few studies on it at present
