Described insecticidal bactericide is made up of the raw material of following parts by weight: Succus Momordicae charantiae 30-35 part, Loquat Leaf powder 15-20 part, Rhizoma Dioscoreae Bulbiferae powder 10-15 part, spaonin powder 10-15 part, tea seed powder 7-11 part, hectorite powder 5-9 part, cm-chitosan 5-9 part, castor seeds powder 4-7 part, Semen Raphani powder 3-5 part, talcum powder 3-5 part, Kathon CG 2-3 part, chilli seed powder 1-2 part, realgar 1-2 part.
The packing film making to obtain that adds of this insecticidal bactericide has excellent pesticide-germicide effect, thus available protecting seed, avoid the mold of seed and insect pest to destroy, and this insecticidal bactericide remain in plant root after packing film dissolves, and protects plant further.
Described Succus Momordicae charantiae is the filtrate of being filtered gained by equivalent balsam pear and water after squeezing the juice.
Plant the preparation method with water-soluble seed packaging film, comprise the steps:
(1) first vinylformic acid, vinyl acetate and Diisopropyl azodicarboxylate are added in reactor, prior to supersound process 30min under ultrasonic frequency 40kHz, power 50W after mixing, microwave treatment 15min under microwave frequency 2450MHz, power 800W again, to be cooledly to room temperature, add nano aluminium trichloride and ethanol, mixture is heated to reflux state insulation 15min, then concentrating under reduced pressure is except desolventizing, and residuum is material I;
(2) sodium bentonite, ramie stalk ash and sepiolite powder are heated to 80-90 DEG C of insulation mixing 15min, then add Xylo-Mucine and rice bran wax, continue insulation mixing 10min, obtain material II;
(3) material I, polyacrylamide and tributyl citrate are mixed, be heated to 100-110 DEG C of insulation 15min, then add material II, glucoside, insecticidal bactericide, polypropylene glycerol aether and water again after being cooled to room temperature, after mixing, namely obtain Preblend;
(4) by Preblend in 3500-4000rpm/min homogenous disperse 10-15min, then through casting film-forming and obtained packing film after drying.
The invention has the beneficial effects as follows: the present invention adopts ultrasonic wave and microwave-assisted to obtain acrylic acid modified polyvinyl alcohol; improve productive rate and shorten preparation time; and be aided with water-soluble polyacrylamide and several functions auxiliary agent; the water-soluble seed packaging film of obtained plantation; this packing film by force water-soluble, can dissolve completely between temperature 5-25 DEG C, and lysate to seed germination and soil protection harmless; thus protection seed, improve rate of emergence.
