Abstract

The invention discloses a formula of an organic-inorganic composite biogas slurry fertilizer special for lycium barbarum L., and belongs to the technical field of liquid fertilizer production. According to the formula, after biogas slurry as a main raw material is filtered, urea, monoammonium phosphate, potassium sulphate, potassium fulvic acid and polyaspartic acid / salt are added in a specializedratio according to the contents of nutritional ingredients and the fertilizer requirement of the lycium barbarum L., so that the organic-inorganic composite biogas slurry fertilizer is prepared. Theformula of the organic-inorganic composite biogas slurry fertilizer special for the lycium barbarum L. has the advantages that the soil properties are improved, diseases and insect pests are reduced,the absorption efficiency of crops is high, the yield and the quality of the lycium barbarum L. are improved, and the formula is of great popularization significance.

Description

technical field [0001] The invention relates to the technical field of liquid fertilizer production, in particular to an organic-inorganic composite biogas liquid fertilizer for wolfberry and a preparation method thereof. Background technique [0002] Ningxia Lycium barbarum (Lycium barbarum L.), is a perennial deciduous shrub, the fruit has a wide range of medicinal and economic value. It is mainly distributed in the northwest region of my country. It likes arid and cool climate and has strong cold resistance. It mostly grows in alkaline soil and sandy soil, and is not suitable for survival in acidic soil. [0003] Ningxia has the largest area of ​​artificial wolfberry cultivation in my country. The extremely arid environment has promoted the development of drip irrigation planting of wolfberry in Ningxia. The promotion of this technology can effectively achieve the purpose of saving water. The traditional fertilization method of wolfberry is manual spreading, which requir...
