Abstract

The invention discloses water-retaining slow-release fertilizer special for Chinese cabbages. The water-retaining slow-release fertilizer is prepared from rapeseed dregs, carbonized straw, peat, duck dung, pleurotus ostreatus residues , urea, diammonium phosphate, calcium superphosphate, potassium sulfate, potassium chloride, potassium nitrate, polyurethane, magnesium hydroxide, quicklime, trace elements, a water-retaining slow-release agent, bacillus subtilis, bacillus licheniformis, yttrium nitrate, rotenone, nano-tea polyphenols, nano-hydroquinone and citric acid. The water-retaining slow-release fertilizer special for the Chinese cabbages is reasonable in formula and good in water-retaining and slow-release effects, the growth of the Chinese cabbages can be promoted, and the quality of the Chinese cabbages is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special water-retaining slow-release fertilizer for Chinese cabbage. Background technique [0002] As a widely cultivated and edible leafy vegetable, cabbage is an important source of vitamins, proteins, amino acids, sugars, minerals and other organic and inorganic nutrients for people to obtain daily. Chinese cabbage has special requirements for nutrient elements. In order to meet the requirements of Chinese cabbage throughout the growth period and increase the yield of Chinese cabbage, slow-release fertilizers are often used at present. However, the slow-release fertilizer slow-release effect of existing fertilizers is not ideal, and unreasonable fertilization generally exists in cabbage production. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a special water-retaining and slow-release f...
