Abstract

The invention discloses a special fertilizer for asparagus in coastal saline-alkali land and a preparation method of the special fertilizer, and belongs to the field of plant bioengineering. The special fertilizer comprises the following raw materials: urea, calcium superphosphate, potassium sulfate, magnesium sulfate, ferrous sulfate, zinc sulfate, organic matters, chitosan oligosaccharide, a fertilizer additive, livestock and poultry manure dried after fermentation and deodorization, and an NAM additive. The preparation method of the special fertilizer comprises the steps of crushing, primary mixing, secondary mixing and tertiary mixing. The special fertilizer for the asparagus in the coastal saline-alkali land can improve saline-alkali soil, meets the absorption and utilization rule of main nutrients of the asparagus and remarkably improves the yield of the asparagus.

Description

technical field [0001] The invention relates to a special fertilizer for asparagus in coastal saline-alkali land and a preparation method thereof, belonging to the field of plant bioengineering. Background technique [0002] Asparagus is a perennial perennial plant, which mainly eats its tender stems. It not only contains rich nutrients, but also has high medicinal and health effects. It is listed as one of the "Top Ten Famous Dishes" in the world. It enjoys the reputation of "King of Vegetables" in the international market. my country's asparagus planting area ranks first in the world, and it is the main export-oriented vegetable. [0003] Asparagus has strong salt-alkali tolerance and can grow normally in soil with a salt content of ≤0.3%. It is a pioneer plant for the development and utilization of saline-alkali land. my country's arable land resources are becoming increasingly tense, and land resources have become a bottleneck restricting the development of my country'...
