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 novel 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 made into 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 obtain 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, the chitosan was made into a 5% weakly acidic solution. Then mix sodium chlorite and citric acid in a weight ratio of 1:3, then slowly add chitosan into the weakly acidic solution under stirring, 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%. The output of cabbage increased by 40%, that of eggplant by 19%, that of green pepper by 20%, that of radish by 24%, and that of peach by 17%. No serious diseases occurred during the growth period.

Abstract

A strong-antibacterial multi-functional agricultural chemical used also as fertilizer is prepared from deacetylated chitin and its derivative, ClO2, and vegetative nutrients through preparing the solution of deacetylated chitin or its derivative, slowly adding ClO2 while stirring, reaction, adding vegetative nutrients and stirring.

Description

Technical field: [0001] The invention relates to a method for preparing a strong antibacterial and multifunctional marine biological agricultural preparation for plant disinfection by modifying chitin and its derivatives derived from marine crustaceans with an antibacterial strengthening factor, and supplementing with general plant nutrients. The preparation not only has a strong killing effect on bacilli and cocci, but also has a strong killing effect on fungi and viruses. It can not only prevent and control plant diseases, but also be beneficial to natural environmental protection, and can also be used for daily disinfection and prevention of cross-infection of diseases. Patent classification number A01N65 / 00. 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 ch...
