The invention discloses an extraction method of an allelochemical substance resisting microalgae from ruppia maritima. Petroleum ether is adopted as a solvent, the allelochemical substance is extracted from the ruppia maritima, during extraction, the extraction operation is conducted on the ruppia maritima three times by adopting the petroleum ether at 15-30 DEG C according to the ratio of 1:10 (m:v), after the extraction operation, organic phase materials are mixed, through pressure reduction and concentration, an organic solvent is volatilized, and the allelochemical substance of the ruppia maritima is obtained; after dilution, the allelochemical substance is applied to algal inhibition. It is shown through an experiment result that the allelochemical substance extracted from the ruppia maritima by adopting the petroleum ether has an efficient inhibiting effect on microcystis aeruginosa, the addition quantity of the allelochemical substance is 90-200 mg/L, the rate of inhibiting the microcystis aeruginosa is 50-95%, and under the condition of the inhibiting rate after seven and a half days, the concentration of the allelochemical substance is 92 mg/L. After 30 days, the allelochemical substance can be naturally degraded and cannot cause secondary pollution to a water environment. The extraction method has the advantage of being simple, high in ecological safety and the like, and provides the scientific basis for inhibiting methods for cyanobacterial bloom by utilizing the allelochemical substance in the water environment protection field.

The invention provides a method for preparing microcapsule termite poison bait. The method comprises the steps of 1, mixing a chitinase inhibitor pesticide with edible vegetable oil, and conducting grinding to obtain an oil-pesticide mixture; 2, adding an insect attractant, a surface active agent and water to the oil-pesticide mixture, and conducting stirring to obtain dispersion liquid; 2, adding gelatin aqueous solution and ethyl alcohol to the dispersion liquid, and conducting freezing at 0-2 DEG C; 4, adding Arabic gum aqueous solution to the frozen dispersion liquid to prepare a microcapsule water suspension; 5, mixing a dried and smashed waste agaric culture medium with the microcapsule water suspension, and conducting drying to obtain the powdery microcapsule termite poison bait. By the adoption of the poison bait, a queen ant can not spawn or can only spawn addle-eggs after being poisoned, in this way, larvae can not be produced, the whole ant colony loses reproduction ability, larvae die several days later due to the failure in normal molting and growth after being fed, and therefore the whole termite population can be killed completely.

The invention relates to the field of peach planting and discloses a method for preventing and curing aphid diseases of peaches. The method comprises the steps of: (1) in autumn, applying fertilizer containing Chinese honey locust, ailanthus altissima, Chinese soapberry and albizia bark to soil, so that tree bodies can perspire and dissipate a chemical substance with special odor which can stimulate nerves of aphids and effectively reduce a breeding rate of aphids; (2) in winter, applying a protective solution to peaches, so that eggs of aphids can be effectively killed, peaches can be prevented from being infected with other diseases and pests, such as spider mites and leaf miners, and inhabiting of parasites and germs can be prevented; (3) in spring, after blooming is over, spraying insecticide liquid to whole plants, wherein the insecticide liquid is lethal to aphids with good vitality and can thoroughly eliminate a few of remaining aphids and other pests, dispel birds, protect flowers and fruits, increase the nutrient level, and prevent and cure powdery mildew and canker. The method is safe and harmless and achieves an aphid control rate of 100%.
