Description
Technical Field
The invention relates to the technical field of pest control, in particular to an underground pest inhibitor and a preparation method and application thereof.
Background
Subterranean pests refer to omnivorous insects that live in the soil throughout life or some stage of life and harm the underground parts, seeds, seedlings or near-soil surface stems of plants. The soil insects are various in types, mainly comprise 10 types of mole cricket, grub, wireworm, cutworm, root maggot, root bug, root aphid, pangolin scales, cricket, root scale, root leaf beetle, root longicorn, root weevil, termite and the like, the total number of the species is more than 200, the species belongs to 8-mesh 36-family, and the species are distributed in each part of China. The species of underground pests vary from place to place, and generally occur in dry farming areas, particularly mole cricket, grub, wireworm, cutworm and root maggot. When crops and the like are damaged, the light plants will wither and slow in growth, and the heavy plants will be withered and die, so that seedling shortage and ridge breaking are caused, and the yield is reduced. Some kinds are harmful to larvae, and some kinds are harmful to adults and young (or young) insects. The modes of harm can be divided into 3 categories: underground parts which live in the soil for a long time and are harmful plants; the night in the daytime is harmful near the soil surface; it is harmful both above ground and underground.
The shape of the underground pests is mostly long and spindle-shaped, the body pigment is degraded, and some organs are developed or degraded, such as the front foot of mole cricket is characterized as digging foot, and the underground pests are suitable for digging soil and advancing in the soil. The normal action of some coleoptera or eyes in soil shows obvious seasonality, mainly because of the sensitive reaction of underground pests to soil temperature and soil moisture, the temperature and humidity conditions of the surface soil layers in winter and summer are not suitable to move to the deep layer, the temperature and humidity conditions of spring and autumn move from the deep layer to the surface soil layer, and at this time, the seedling stage of crops is generally positive, so that sufficient food conditions are provided for the crops. At present, the existing underground pest control measures mainly comprise:
(1) artificially trapping and killing larvae: when the occurrence amount is small and the hay algae is in the nursery, the surface soil around the damaged nursery stock is slightly supported by hands, and then the latent larvae can be found. This method is time consuming, laborious and incomplete.
(2) Trapping and killing adults: from 3 months to 5 months, trapping and killing with black light lamp and sweet and sour wine. The formula of the luring sugar-vinegar wine comprises the following components: 6 parts of white sugar, 3 parts of rice vinegar, 1 part of white spirit, 2 parts of water and a small amount of dipterex. Placing on the ground before dark and recovering after tomorrow. The retrieved moths were killed. The method can only trap and kill adult moths, but cannot kill larvae.
(3) 2.5 percent of trichlorfon powder, 22.5 kilograms of fine soil and 337.5 kilograms of fine soil per hectare are evenly spread on the ground. Spraying 800-1000 times of 90% trichlorfon solution or 1000 times of 50% phoxim solution. The method can cause drug residue, harm to health, pollution to soil, and drug resistance after long-term use.
In addition, there are some documents in the prior art for pest control using microorganisms, for example, in patent document CN109574724A, a bio-organic fertilizer having the function of controlling soil pests is disclosed, which comprises the following components in parts by weight: 40-60 parts of organic fertilizer, 45-52 parts of tobacco powder and 0.5-1.5 parts of microbial agent. Wherein the microbial agent is at least one of Aspergillus niger, Trichoderma viride, Bacillus licheniformis, Bacillus subtilis, Bacillus laterosporus, Bacillus thuringiensis, Pseudomonas fluorescens PSl, Bacillus pumilus SQR-N43 and Bacillus N11. Therefore, the organic fertilizer has less bacteria content, and because the microbial agent is greatly influenced by environmental factors, the production and preparation are complex, and the cost is high, the effect of preventing and controlling the soil insects is limited, and the organic fertilizer is not suitable for large-scale application.
In summary, no drug and method which have good prevention and control effects on underground pests, can provide nutrition for crops, cannot cause pollution and damage to soil and crops, have low cost, cannot generate drug resistance, are convenient to operate and have the effect of durably inhibiting the underground pests exist at present.
