Earthworm hydrolysate and rare earth compound active foliar liquid fertilizer as well as preparation method and using method thereof

Abstract

The invention discloses earthworm hydrolysate and rare earth compound active foliar liquid fertilizer as well as a preparation method and a using method thereof. The liquid fertilizer comprises the following components in percentage by weight: 2-3% of agricultural rare earth, 0.6-1% of fulvic acid, 0.8-1.2% of compound sodium nitrophenolate and the balance being an earthworm hydrolysis solution. The preparation method comprises the following steps: 1) pulping earthworms; 2) mixing the earthworm pulp with water; 3) adjusting pH value; 4) filtering; 5) adding earthworm hydrolysis amino acid; 6) adding the agricultural rare earth and reacting; 7) adding the fulvic acid and reacting; 8) adding the compound sodium nitrophenolate and reacting; and 9) filtering, sterilizing and filling to obtain a finished product. Compared to the prior art, the liquid fertilizer disclosed by the invention can chelate earthworm hydrolysate and rare earth element, and can realize coexistence with the compound sodium nitrophenolate, which serves as a growth regulator having a strong cell activating function; and the liquid fertilizer, applied to foliages of agricultural crops and commercial crops, can significantly improve yield and disease resistance of the crops to achieve an ideal fertilizer efficiency; therefore, the liquid fertilizer has characteristics of improving crop quality and increasing output.

Description

technical field

[0001] The invention belongs to the technical field of agricultural fertilizer production, and in particular relates to a compound active foliage liquid fertilizer of earthworm hydrolyzate and rare earth, and its preparation and use methods. Background technique

[0002] The agricultural use of rare earths is an application field of rare earths independently created by my country. Rare earth agricultural research began in the early 1970s in my country. It has been 40 years since the widespread use of rare earths in the mid-1980s. A series of important breakthroughs have been made not only in the agricultural technology of rare earths, but also in the research of basic theories, and have produced great economic benefits. The research results show that: rare earths can stimulate the growth of crops, and show the characteristics of stages. Whether it is a single rare earth or a mixture of rare earths, they all show quite effective effects similar to trace elem...
