The invention relates to a method for improving the effect of entomopathogenic nematodes on controlling chive maggots. A synergistic suspension is obtained by mixing a thiamethoxam dilution with entomopathogenic nematodes meeting the detection conditions, and the concentration of nematodes in the synergistic suspension is 500-1000IJS / mL, the concentration of thiamethoxam is 12-15mg / L; the synergistic suspension is used to kill the maggot larvae in the larval stage of the leek maggot, and normal field management is carried out after application; under field conditions, the entomopathogenic nematode is used to control the maggot maggot The method of adding low-concentration thiamethoxam can significantly improve the effect of nematodes on leeks, scallions, onions, shallots, garlic and other vegetable crops that are easily harmed by leek maggots. The control of nematodes and thiamethoxam on leek maggots shows The obvious synergistic effect can significantly reduce the usage of thiamethoxam and other insecticides, combined with the trapping and killing technology of adults with black sticky boards, it can effectively reduce the number of insect populations in the field, so that the prevention and control of leek maggots can truly achieve the goal of safety and pollution-free.

The invention discloses a reagent for prevention and treatment of fruit disease of bagging fruit. The raw material of the reagent consists of chloramines T 50 percent to 80 percent, diatomite 11 percent to 25 percent, stearic acid 3 percent to eight percent, shellac 5 percent to 13 percent and hydroxypropyl methyl cellulose 1 percent to 4 percent. The invention also discloses the preparation method for the reagent which is as follows that three different particles are prepared with the formula according to different ratio so that the particle can release germicide at different time and disease prevention for a long time can be achieved. According to the characteristics of bagging fruit disease occurrence, the reagent provided by the invention changes traditional method for medicine application, not only reducing medicine application cost, but also improving prevention efficiency, increasing harvest level and commodity rate and reducing environmental pollution, moreover, win-win resultcan be achieved.

This invention relates to an electric control cabinet, in particular relates to a non-negative pressure water supply system with an intelligent dustproof and waterproof portable control cabinet, and is used for the electric control of a non-negative pressure water supply system. The electric control cabinet comprises a cabinet body, a non-negative pressure water supply control unit, a variable frequency device, a contact device, a wiring terminal, an electronic type data transmission power meter and water meter, and a temperature humidity control system and a translation rotating mechanism located on the bottom of the cabinet body. The non-negative pressure water supply control unit comprises a video surveillance module, an attendance system module, a PLC control device, an instrument meter power supply, a relay, and a long-distance communications module. The electric control cabinet overcomes the challenges that the existing electrical control cabinets do not meet the conditions of drying, constant temperature, dust proof, water resistance and the like, achieves the intelligent control of humidity and temperature, has the remote communication function, and is up to IP55 in the dustproof and waterproof rank.

The invention provides a slow-release algae-inhibiting microsphere, a preparation method and application thereof. The slow-release algae-inhibiting microspheres are prepared from the following raw materials: luteolin 1%-1.5% (w / v), olive oil 18%-20% (w / v), emulsifier 10%-12% (w / v), co-emulsifier 10%~12% (w / v), sodium alginate 1%~2.5% (w / v), chitosan 0.2%~0.3% (w / v), chloride Calcium 4%-8% (w / v), cross-linking agent 0.5%-1% (v / v). The slow-release algae-inhibiting microspheres provided by the present invention can slow down and control the release rate of luteolin, and the preparation process is simple, the cost is low, and there is no pollution to the environment. Through the sustained and slow release of luteolin, it can significantly It effectively inhibits the growth of Microcystis and at the same time effectively inhibits the release of microcystins (MCs), without the need to repeatedly add algicides, and has a long-term and stable effect on effectively inhibiting the outbreak of cyanobacteria blooms.
