Fig special-purposed topdressing, and preparation method and application thereof

Abstract

The invention discloses a fig special-purposed topdressing. The topdressing comprises the following components, by weight: 9-11 parts of urea, 19-21 parts of diammonium phosphate, 23-25 parts of potassium sulfate, 21-23 parts of gypsum powder, 1.5-2.0 parts of borax, 1.3-1.8 parts of zinc sulfate, 0.9-1.1 parts of ferrous sulfate, 3-5 parts of amino acid, 3-5 parts of humic acid, 3-5 parts of fulvic acid, and 3-5 parts of straw vinegar. The invention also discloses a preparation method and application method of the fig special-purposed topdressing. With the special-purposed topdressing, fig quality can be improved. When the topdressing is applied in farms in Baitu Town of Jurong City, fig leaves are thickened, chlorophyll is increased, fig root systems are thickened and increased, and fig yield is increased by 8-10%. Also, fig commodity is substantially improved. Fruit hardness is increased, and the fruits are brightly colored. With the increase in fig yield and quality, the benefit per Mu is increased by 1200-2000yuan. Chemical fertilizer application is reduced, such that agricultural non-point source pollution is reduced, and soil environment is improved.

Description

technical field

[0001] The invention belongs to the field of compound fertilizers, in particular to a special topdressing fertilizer for figs and its preparation method and application. Background technique

[0002] As figs are gradually favored by the public, it is more urgent to fertilize figs rationally. The current method of topdressing figs is extensive and labor-intensive, resulting in insufficient fertilizer efficiency and high labor costs. In view of the current situation, a special topdressing fertilizer for sausage-shaped figs that can save labor and improve fertilizer efficiency has been developed. It can supply fertilizer nutrients suitable for the demand ratio during the critical growth period of figs. The fertilization method is simpler, the fertilizer nutrient ratio is more targeted, and the fertilizer utilization higher efficiency. Contents of the invention
