Description
Technical Field
The invention relates to the technical field of prevention and control of wheat aphids, and particularly relates to a wheat aphid prevention and control inhibitor and a preparation method thereof.
Background
Wheat (Triticum aestivum L.) is a gramineous plant and one of three major cereals, is almost all edible, can be used for making bread, steamed bread, biscuits, noodles and other foods, and can be made into beer, alcohol, white spirit (such as vodka) or biomass fuel after fermentation. The main pests and diseases generated by the method include wheat aphids, red spiders, soil insects and the like. In 9/15/2020, the book of first class crop pest and disease records of agricultural rural ministry publishes that wheat aphids are selected as pest and disease records. Nymphs and adults of wheat aphids often gather on leaves, stems and ears to prick and suck juice, photosynthesis, nutrition absorption and conduction of wheat are affected, damaged parts are yellow and small spots at first and then are striped spots, and the whole plant withers to death. Wheat is damaged at the ear part after heading, blighted grains are formed, and the thousand grain weight is reduced, so that the yield is reduced. In recent years, along with improvement of water and fertilizer conditions and increase of planting density, wheat aphids tend to grow more and more year by year, and the wheat yield is greatly influenced. The weight of the thousand grains is generally reduced by 3-5g, and the weight of the thousand grains can be more than 15 g.
In general, the reasonable layout or the selection of the insect-resistant and disease-resistant wheat varieties is carried out in the agricultural control. However, because wheat has poor disease resistance to aphids, the control measures of wheat aphids mainly depend on various chemical insecticides, such as imidacloprid, acetamiprid, beta-cypermethrin, and the like. However, the chemical agent is extremely or slightly toxic, and thus, the chemical agent will affect the environment and bring disasters to human beings after long-term use. In addition, chemical agents are easy to remain on the surface of plants, and have toxic and side effects on human beings, which threatens human survival. Meanwhile, the wide use of chemical pesticides endangers ecological agriculture, pollutes soil and water resources, and does not accord with the concepts of green, environmental protection and health. A plant-derived pesticide is a novel pesticide having a preventive and therapeutic effect on plant diseases and insect pests, which is prepared from a stable active ingredient contained in a plant and the plant. Due to the special property of the plant pesticide, the pest is difficult to generate drug resistance, and the pesticide has the characteristics of high efficiency, low toxicity, long pesticide effect period, no residue, safety to people and livestock and the like, and is gradually accepted by people. However, plant-derived pesticides have problems such as low extraction rate and poor stability. Therefore, a new environment-friendly agent must be developed to meet the needs of future ecological agriculture development.
For example, patent application with publication number CN 107347518A discloses a wheat aphid inhibitor and a preparation method thereof, the inhibitor is natural, green, environment-friendly, safe and residue-free, but can only reduce aphids by 70-90%, and is difficult to control wheat infected with aphids.
Disclosure of Invention
The invention aims to provide a prevention and control inhibitor capable of improving the prevention and control effect of wheat aphids and inhibiting the wheat aphids.
The invention solves the technical problems through the following technical means:
a wheat aphid prevention and control inhibitor is mainly prepared from the following raw materials in percentage by weight: 1-5% (m/v) of loss control regulator, 1-8% (v/v) of paraffin oil, 1-2 thousandths (m/v) of nano titanium dioxide and kaolin
(mV), the balance being water;
the preparation method of the loss control regulating agent comprises the following steps:
1) Taking oxygen and ammonia gas as gas sources, performing intermittent irradiation treatment on 100-800 mesh adsorption grade attapulgite powder by using plasma with the temperature of 500-1000 ℃ and the power of 1-3KW under a vacuum condition for 5-10 minutes, stopping for 5-10 minutes until the total effective irradiation time reaches 30-60 minutes, and preparing the aminated attapulgite;
2) Under the anaerobic condition of nitrogen protection, performing high-temperature cracking on rice straws for 50-100 minutes at 500-800 ℃ by adopting a muffle furnace to obtain micro-nano biological silicon/carbon;
3) Uniformly mixing the aminated attapulgite and the micro-nano biological silicon/carbon according to the mass ratio of 3-5:1-2 to obtain the disorder control agent.
Has the beneficial effects that: the wheat aphid prevention and control inhibitor can reduce the number of wheat aphids by 98-100% before the coming of the aphids, is obviously higher than the prior art, can suffocate the aphids to die by closing air holes, but does not have expelling performance on the aphids and cannot inhibit the existing aphids, and the prevention and control effect of the wheat aphid prevention and control inhibitor can reach more than 79.55% on the wheat with the existing aphids.
The paraffin oil added in the invention has adhesion and hydrophobic effect, and after the paraffin oil is compounded with the nano titanium dioxide and the kaolin, the hydrophobic property and the adhesion of the composite material are enhanced through the connection of hydrogen bonds. Furthermore, paraffin oils are mineral oils, have a high flash point and low volatility and are stable to light, heat and acids. The coating provides better weather resistance for the coating in field application, reduces industrial pollution and achieves the effect of environmental protection.
The paraffin oil has film forming property and uniformity, and the kaolin is of a sheet structure, so that a thin film can be well formed by spraying the kaolin on the surface of the wheat leaves to cover the surface of the wheat leaves. The nano kaolin and titanium dioxide are added, so that the uniformity and the durability of the prevention and control inhibitor on the surface of the wheat leaves can be effectively improved, and the effect of the prevention and control inhibitor is improved.
The loss control regulator prepared by the invention has the loss control effect, improves the action time of the nano protective film and enhances the prevention and control effect on aphids.
The modified silicone oil in the prior art has low toxicity, and the paraffin oil is nontoxic, can be used in the aspects of food, medicine and the like, and is nontoxic and harmless to the growth of human bodies and plants.
Compared with the prior art, the invention has lower cost and is more environment-friendly.
Preferably, the wheat aphid prevention and control inhibitor is sprayed on the surfaces of wheat leaves infected with aphids or not infected with aphids.
Preferably, when the wheat is sprayed, the wheat is sprayed for 1-3 times in the morning or evening of a fine day.
Preferably, the volume ratio of the oxygen gas to the ammonia gas in the step 1) is 1:1-1:5.
The preparation method of the wheat aphid prevention and control inhibitor comprises the following steps: and mixing the control imbalance control agent, paraffin oil, nano titanium dioxide, kaolin and water to obtain the wheat aphid control inhibitor.
Has the advantages that: the method is simple and convenient to operate, can be used for large-scale operation, and is low in cost. The prevention and control inhibitor prepared by the invention has good prevention, control and inhibition effects on wheat aphids, can reduce the number of the wheat aphids by 98-100% before the coming of the aphids, and has an aphid prevention and control effect of more than 79.55% on the wheat with existing aphids.
Preferably, the loss control regulating agent is mixed with water and stirred to obtain a nano suspension, and then the nano suspension is mixed with paraffin oil, nano titanium dioxide and kaolin and stirred to obtain the wheat aphid prevention and control inhibitor.
