Antibacterial composite fertilizer and its using method

Abstract

A bactericidal compound fertilizer in the form of wettable powder contains phosethyl-Al (20-26 wt.%), metalaxyl (17-23), chlorothalomi (7-16), calcium carbonate, Mo, B, Mg, S, Si and zinc sulfate. Its advantages are easily ripening, high yield of crops (increased by 30-60%), improving soil and high fertility.

Description

Technical field [0001] The invention belongs to fertilizers used by crops, in particular to a compound fertilizer with bactericidal effect and its application method. Background technique [0002] In the process of plant growth, sterilization and fertilization are required, but in the prior art, the two are carried out separately, and the sterilization of plants uses different compounds as hygroscopic and contact soil fungicides, such as: Thiram, Zinc , Captan, etc., the fertilizers needed by plants are divided into fertilizers (barn manure and green manure) and chemical fertilizers (nitrogen, phosphorus and potassium fertilizers); when plants suffer from pests or bacteria, farmers often continue to apply micro-fertilizers, so that plants not only Failure to absorb trace elements will also aggravate the condition. If the bacteria are sterilized first and then fertilized, the roots of the plants will be damaged because the farmers do not prescribe the right medicine, and vari...

Problems solved by technology

[0002] In the process of plant growth, sterilization and fertilization are required, but in the prior art, the two are carried out separately, and the sterilization of plants uses different compounds as hygroscopic and contact soil fungicides, such as: Thiram, Zinc , Captan, etc., the fertilizers needed by plants are divided into fertilizers (barn manure and green manure) and chemical fertilizers (nitrogen, phosphorus and potassium fertilizers); when plants suffer from pests or bacteria, farmers often continue to apply micro-fertilizers, so that plants not only Failure to absorb trace elements will also aggravate the condition. If the bacteria are sterilized first and then fertilized, the roots of the plants will be damaged because the farmers do not prescribe the right medicine, and various nutrients cannot be absorbed. Therefore, the plants cannot get nutrients and cannot grow normally, resulting in stiff seedlings, stiff fruit

In addition, the long-term use of micro-fertilizers with a single element or a small amount of elements to increase crop yields will lead to unbalanced soil nutrient content, soil compaction, increased pathogens, decreased vitality, decreased fertilizer utilization rate, and decreased crop fruit quality, etc.
