Special humic acid blended fertilizer for chilies and preparation method thereof

Abstract

The invention discloses special humic acid blended fertilizer for chilies and a preparation method thereof. The blended fertilizer is prepared from the following components in parts by mass: 217 to 236 parts of urea, 182 to 227 parts of monoammonium phosphate, 250 to 267 parts of potassium chloride and 270 to 347 parts of nitro-humic acid. According to a nutrient resource comprehensive managementtheory and technology of nitrogen real-time monitoring and phosphorus and potassium constant-amount monitoring, three innovation theories of humic acid fertilizer and a chili nutrient needing rule, the fine type and high-activity nitro-humic acid is used as a base material, and harmful substances and bacterial toxins, which are generated due to continuous cropping, are adsorbed and digested through increasing the content of the base material to a greater extent; a damaged root microorganism colony and a structure thereof are repaired; the diversity level of soil microorganisms is improved, andwater, fertilizer, air and heat conditions of soil are regulated and a good environment for crop roots is established. Nitrogen improvement, phosphorus dissolving and potassium promotion are realizedthrough the humic acid and medium trace elements in the soil are activated; root nutrients are balanced and optimized and sufficient nutrients are provided for crops in real time.

Description

technical field [0001] The invention relates to a special humic acid blended fertilizer for peppers and a preparation method thereof, belonging to the technical field of humic acid fertilizers. Background technique [0002] Capsicum is a nutritious vegetable and an indispensable important condiment in daily life that Chinese people generally like to eat. It is one of the vegetable types with the largest planting area in my country. It is widely planted all over our country. However, with the continuation of the pepper industry, the problem of continuous cropping obstacles in many pepper producing areas has become increasingly serious, especially soil-borne diseases. Long-term continuous cropping causes changes in the soil microbial flora, breaks the normal microbial community and its structure in the rhizosphere, reduces the level of microbial diversity, reduces pathogenic antagonists, affects the normal growth and development of peppers, and then affects the yield and qual...

AI Technical Summary

Problems solved by technology

[0004] According to the survey, the main problems in the fertilization of vegetables are: (1) The application of chemical fertilizers is too large, especially nitrogen fertilizer, while the application of potassium fertilizer is insufficient, and the ratio of nitrogen, phosphorus and potassium is seriously out of balance.

(2) Improper application of medium and trace element fertilizers

(3) The amount of organic fertilizer application is relatively insufficient

[0005] At present, the phenomenon of blind fertilization caused by one-sided pursuit of high yield in vegetable production is quite common. As the amount of chemical fertilizers continues to increase, the amount of organic fertilizers is decreasing day by day, and many organic fertilizers are applied in large quantities to vegetable fields without being fully decomposed. , leading to the pollution of soil, groundwater and vegetables, and even the deterioration of soil physical and chemical properties, and the aggravation of pests and diseases
