example 1

[0012] Make chitosan into 3% weakly acidic solution, slowly add 2% chlorine dioxide (ClO 2 ) solution, reacted for 30 minutes, then added 1% urea and 0.5% potassium phosphate, and stirred evenly to obtain a new type of marine biological agricultural preparation.

[0013] It is diluted 200 times and sprayed on the leaves of cucumber and cabbage with a cycle of 10 days. As a result, the yield of cucumber increased by 23%. Cabbage production increased by 37%. No serious diseases occurred during the growth period.

example 2

[0015] Chitosan was formulated into a 1% aqueous solution. Chlorine dioxide (ClO 2 ) gas, reacted for 60 minutes to make the adsorbed ClO 2 The content reaches 2%-3%, and then add 1% urea, 0.5% potassium phosphate, 2% compound amino acid, and 1% trace elements in total, and stir evenly to get a new type of marine biological agricultural preparation.

[0016] It is diluted 300 times and sprayed on the plant foliage with a period of 10 days. As a result, the yield of cucumber increased by 28%, the yield of cabbage increased by 32%, the yield of eggplant increased by 18%, the yield of radish increased by 22%, and the yield of peach increased by 14%. No serious diseases occurred during the growth period.

example 3

[0018] Firstly, chitosan was made into a 5% weakly acidic solution. After mixing sodium chlorite and citric acid in a weight ratio of 1:3, slowly add it to the weakly acidic solution of deacetylated chitosan under stirring, and continue to react for 30 minutes, then add general-purpose phytonutrients and stir evenly A new type of marine biological agricultural preparation is obtained.

[0019] It is diluted 300 times and sprayed on the plant foliage with a period of 10 days. As a result, the yield of cucumber increased by 31%. Cabbage production increased by 40%, eggplant production increased by 19%, green pepper production increased by 20%, radish production increased by 24%, and peach production increased by 17%. No serious diseases occurred during the growth period.

Abstract

The invention relates to a method for preparing a strong antibacterial agricultural bactericide for disinfecting plants by virtue of antibacterial enhancer modified chitin derived from marine crustaceans as well as derivatives thereof. The preparation mainly consists of the following components: chitin deacetylation as well as a derivative thereof and chlorine dioxide, as well as a plant nutrient which serves as an auxiliary element; the preparation method comprises the following steps: preparing the chitin deacetylation and the derivative thereof into a 1-10% weakly acidic solution or a 1-10%neutral solution, slowly adding the chlorine dioxide component under a stirring condition and reacting for 20-90min; and then, adding the plant nutrient and uniformly stirring so as to obtain a marine biological agricultural preparation, wherein the solid content in the preparation is 0.0001-100%. The sterilizing and disinfecting agent disclosed by the invention is simple in implementation process, rich and easily available in raw materials, broad in application scope of products and strong in sterilizing and disinfecting effects; and meanwhile, the sterilizing and disinfecting agent has effects of fertilizing and yield increasing, and can be widely sprayed on plant leaves or irrigated to roots and tubers.

Description

Technical field: [0001] The invention belongs to the technical field of chemical product preparation, and relates to a method for preparing a strong antibacterial agricultural fungicide for plant disinfection by modifying chitin derived from marine crustaceans and its derivatives with an antibacterial strengthening factor. technical background: [0002] At present, various liquid fertilizers are applied to crops, such as foliar fertilizer, amino acid liquid fertilizer, trace element liquid fertilizer, etc. These fertilizers are superior to traditional organic fertilizers and single chemical fertilizers in some aspects. However, due to the long-term and large-scale application of pesticides and chemical fertilizers, the negative impact cannot be eliminated for a while. (Such as soil compaction, single-salt poisoning of plants, decline in crop yield and quality.) Especially serious is the impact of pesticides and fertilizers on the ecological environment, causing a large numbe...
