Abstract
The invention relates to a special fertilizer for Zhanhua winter jujubes, a preparation method and the application thereof. The special fertilizer for Zhanhua winter jujubes comprises the following raw materials in parts by mass: 50 to 70 parts of zymolysing oil residues, 10 to 20 parts of urea, 5 to 15 parts of DAP (diammonium phosphate), 10 to 18 parts of potassium sulfate, 0.5 to 1 part of ferrous sulphate, 0.3 to 0.7 part of zinc sulfate and 0.2 to 0.4 part of boric acid, wherein the zymolysing oil residue is a product produced by carrying out biodegradation on the oil residues by using lipases in bacillus subtilis fermentation broth and yarrowia lipolytica fermentation broth and proteases in geotrichum candidum fermentation broth and lactobacillus plantarum fermentation broth. The special fertilizer of the invention is prepared especially according to the nutrient status of soils in the main producing areas of Zhanhua winter jujubes and the regulation of nutrient absorption of the jujubes, and has the advantages of reasonable nutrient ratio and strong pertinence. The special fertilizer can reduce the salt damages caused by fertilizing and the organic and inorganic combination can improve the soil fertility.
Description
technical field [0001] The invention relates to a special fertilizer for Zhanhua Dongzao and a preparation method thereof, belonging to the technical field of fertilizer production. Background technique [0002] Zhanhua Dongzao is a late-maturing fresh fruit, which generally begins to mature in late September. Its peel is bright red, sweet and crisp, rich in nutrition and excellent in quality. It is known as the king of all kinds of fruits. Zhanhua Dongzao has a long history of cultivation, and the oldest jujube tree has a history of more than 600 years. Since the 1980s, the planting area of Zhanhua Dongzao has expanded rapidly. At present, Zhanhua County has developed 80,000 mu of densely planted gardens, with an annual output of 2 million kg. In 1995, Zhanhua County was named the "Hometown of Chinese Winter Jujubes" in the selection activity of "The Hometown of the First Hundred Specialty Products in China". [0003] Zhanhua County is the main production area of Zh...
