It has entered the rainy season and has more rain, which is suitable for the growth of crops. However, with the gradual increase of temperature, the occurrence of pests and diseases on cotton, rice, pepper, edamame, corn and other crops has become more serious. How to effectively use pesticides to control pests and diseases of crops during the rainy season, the author introduces the following seven to farmers point.
First, the use of systemic pesticides systemic pesticides can enter the plant through the roots, stems, leaves and other parts of the plant, and transported to other parts, to play a poisoning effect in a certain period of time. More than 80% of the active ingredients are absorbed into the tissues by the crops 4-5 hours after the application of pesticides such as monocrotophos and omethoate, and 4-5 hours after the application of pesticides such as yam, carbendazim, rust, and leaf dry. It will not affect the efficacy of the rain.
Second, the use of fast-acting pesticides, dichlorvos, monocrotophos, methamidophos, chlorpyrifos, deltamethrin, etc. are quick-acting pesticides. These pesticides have a strong contact or killing effect, and the poisoning effect is rapid. After 1 to 2 hours, the pests can be killed.
3. Jinggangmycin in the selection of rain-tolerant pesticide fungicides has good rain resistance. After 1-2 hours of application, even if it encounters showers, it will not affect the effect.
4. Adding an adhesive adhesive to the drug solution can increase the adhesion ability of the pesticide on the surface of the plant and the pest. It is not easy to wash off the drug in the case of moderate rain after application, and improve the control effect of the pesticide from high. When preparing pesticides, add 50-70 grams of adhesive for every 50 kg of liquid medicine, such as washing powder, stir evenly, and use it in time after preparation, the effect is good.
Fifth, timely application of pesticides according to the life cycle and activity rules of pests. Regardless of the pest, the resistance during the larval period is weak, and the pest can be killed with a low concentration of the liquid. For some pests coming out at night, choose to apply the medicine in the evening, so that the medicine is quickly absorbed by the plants, and the pests come out for food within 2-3 hours, resulting in poisoning.
Sixth, look at the days before the application of drugs, pay attention to the dynamics of weather changes, and seize the gap after spraying the pesticide. Don't spray when you are going to rain or when it is raining.
7. Improve the application method. Select systemic insecticides to occur in pests. The fine soil is applied to the mud layer near the root of the plant, and the whole plant is spread after the plant is absorbed, causing the pest to die and poisoning. This method of applying in the root zone avoids being washed away by rain and is particularly suitable for use during the rainy season.
Container house are easy to install and disassemble, and have obvious advantages in use!
Container house are also a kind of Prefab Houses, which can meet the needs of daily living, and also have the advantages of convenient disassembly and installation, and are used in many construction sites. Moreover, the size and specifications of the house can be customized and processed, and the installation can be completed quickly, which is also conducive to long-term use. So what are its advantages?
Easy to transport
Compared with other construction houses, container houses are convenient for daily use and easy to transport, and are very suitable for units that frequently change construction sites. The container house itself is made of steel plate, which is economical, environmentally friendly and durable, and it adopts a steel frame as a whole, which has a very good anti-seismic effect, strong stability, and a certain degree of airtightness. While it is convenient for daily use, it can also avoid water ingress, etc., and can also meet people's living needs.
Various spaces can be formed
This type of house does not need to lay a foundation, it can be constructed and installed directly, and can generate a variety of space combinations. In particular, some large-scale construction sites may not only need basic dormitories, but also need meeting rooms, kitchens, and bathrooms. Compared with directly building other houses, the advantages of using container houses are also very obvious. Its standard width is generally about two or three meters, and houses of different sizes can also be customized, and the construction is also very simple. In particular, the construction of the Folding Container House only takes 10 minutes and is very simple.
Easy to disassemble
The steel plates of the container can be disassembled, and the performance is stable, and the material can be recycled again, and there is no need to worry about generating construction waste, and it can also be recycled. Because the material itself has undergone anti-corrosion treatment, it also has a certain fire performance, so it can be cleaned frequently to ensure its long-term use.
cost-effective
The container house can be used for a long time after one-time installation, and it can also be disassembled and installed again at any time with the relocation of the construction site, which can save a lot of construction costs for dormitories, and is also very cost-effective. Moreover, it is an integral structure, and the interior can be decorated with wooden veneers, etc. It can also be moved synchronously, and it can save a lot of costs for long-term use.
