Complex liquid coated medical fertilizer for organically preventing and curing root diseases and manufacture process thereof

Abstract

The invention discloses complex liquid coated medical fertilizer for organically preventing and curing root diseases and the manufacture process thereof. Complex liquid of organic bactericide pesticide and a swelling agent are coated on the surfaces of compound fertilizer particles, and a coating agent is coated on the outermost layer. The compound fertilizer particles are nitrogen-phosphorus-potassium mixed fertilizer particles. The bactericide pesticide is one of DT bactericide, antibiotic 120 bactericide or validamycin antibiotics, the swelling agent is double baking powder, and the two preparations are mixed to be complex liquid according to maintenance dose. The coating agent is seaweed glue, and the raw material weight percentage is as follows: 96 to 98 percent of compound fertilizer particles, 0.3 to 1 percent of bactericide pesticide, 1 to 2 percent of swelling agent and 0.5 to 1.7 percent of coating agent. In the invention, organic bactericide pesticide such as the DT bactericide and the like is mixed with the swelling agent to form complex liquid, a drug micron sprayer is used for spraying on the outer surfaces of the compound fertilizer particles, and then a certain amount of seaweed glue coating agent is added for coating the outermost layer. Therefore, the complex liquid coated medical fertilizer is prepared. The nutrition slowly releasing and disease-resisting and sterilizing functions of the compound fertilizer can be added, and the lasting effect and the utilization efficiency of fertilizer and pesticide can be improved.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production in the chemical industry, and relates to a medicinal fertilizer with a compound liquid coating of an organic fungicide for preventing root diseases and an expanding agent and a production process thereof. Background technique [0002] With the urbanization transfer of the rural labor force and the rapid development of agricultural mechanization, modernization, and standardization, the requirements for the control of diseases, insects, weeds, and fertilization in agricultural production management are becoming simple, fast, safe, and environmentally friendly. "Complete, the development of "one job with multiple effects". In conventional agricultural production management, fertilization of crops during sowing and spraying or spraying of pesticides for disease control and pest control are carried out step by step. There are four most prominent deficiencies in the existing compo...

AI Technical Summary

Problems solved by technology

[0003]1. Single nutritional function

The existing compound fertilizer product technology only has the function of supplying crop nutrition, which is not conducive to the simultaneous implementation of fertilization and medicine in the agricultural production management of "two birds with one stone, one job with multiple effects".

[0004]2. Time-consuming and labor-intensive

In the process of agricultural production, during the annual autumn planting and summer sowing period, chemical fertilizers are applied followed by pesticides, which is labor-intensive, low-efficiency, labor-intensive and time-consuming

[0005]3. Long-term use of chemical fertilizers increases soil salinity, soil compaction, poor ventilation, and poor physical properties cause poor growth of plant roots

[0006]4. Unsafe use of pesticides and serious public hazards

We have carried out a large amount of research tests, and carry out scientific and technological novelty search, although there are titles as "a kind of high-efficiency fish fertilizer of organic type", the Chinese patent application publication number is CN1480029A; , the Chinese patent application publication number is CN1480030A; With the name "enzyme bacteria biological organic fish fertilizer and production method thereof", the Chinese patent application publication number is the fertilizer of CN1757616A, these are only special fertilizers for fish; Fertilizer granule preparation and its preparation method and device" (Chinese patent application number: 87107446) and "a kind of fertilizer plus pesticide composition" (Chinese patent application number: 200510090040.0), both of which are medicinal fertilizers sprayed by foliar liquid , there are cumbersome methods of use, unsafe spraying, diffuse smell of spraying pesticides, causing environmental pollution, etc.

[0008] After searching the scientific and technological literature, no product of the organic fungicide and bulking agent compound liquid coating fertilizer preparation for root disease control was found
