Pakchoi organic composite fertilizer

Abstract

The invention relates to pakchoi organic composite fertilizer. The pakchoi organic composite fertilizer is characterized in that medium and trace elements needed by multiple plants are mixed with inorganic fertilizer and organic fertilizer; and simultaneously, auxiliary agents capable of improving an absorption and utilization rate for a plant and increasing fertilizer slow-release performances and effective microorganisms are added into the mixture to be prepared into specialized composite fertilizer particles through proper fermentation and processing. The pakchoi organic composite fertilizer has the advantages that scopes of suitable regions and soil types are wide; base fertilizer one-step application can be realized in fertilizer application and topdressing can be carried out later according to needs; pakchoi growth needs are satisfies; and effects of yield increase and harvest increase are realized.

Description

technical field [0001] The application relates to the field of fertilizers, in particular to a pakchoi organic compound fertilizer. Background technique [0002] Chinese cabbage (Brassica rapa L.) is also known as non-heading cabbage. Native to my country, it is distributed throughout the north and south, and is widely cultivated in my country. Brassica genus Brassica, one or two-year herbaceous plants, often cultivated as annuals. The stems and leaves of Chinese cabbage are edible, the plants are relatively short, the root system is shallow, and the fibrous roots are well developed. The leaves are light green to dark green, obovate or elliptic, smooth or wrinkled, and a few have hairs. The petiole is thick, white or green. No balls. The flowers are yellow and the seeds are nearly round. According to the determination, Chinese cabbage is the vegetable with the most abundant minerals and vitamins. Chinese cabbage likes to be cold and cold, and it is resistant to low an...

Problems solved by technology

[0004] In addition, due to the blind use of large amounts of nitrogen, phosphorus and potassium fertilizers in traditional fertilizers, nutrients in the soil accumulate, resulting in waste of fertilizers and serious environmental problems

According to reports, the utilization rate of nitrogen fertilizer in my country is 30% to 50%, the utilization rate of phosphorus fertilizer is about 10-15%, and the utilization rate of potassium fertilizer is about 30-60%. The nutrient release of existing fertilizers and the absorption of nutrients by crops are often not synchronized, so that excess nutrients enter the water body and the atmosphere through volatilization and wetting in the soil.
