How to prevent vegetable diseases in greenhouses

After years of exploration and experimentation, the diseases of greenhouse vegetables should be taken as a comprehensive prevention and treatment means mainly consisting of agricultural control and supplemented by chemical control. The specific measures include the following: 1. Destroying the suitable temperature and humidity environment of pathogens and controlling the occurrence of diseases. Use open ventilation to adjust and control. It is well ventilated on sunny days, and it is well ventilated on cloudy days. It is not ventilated on rainy or cold days. In May, the greenhouse membranes should be removed. In this way, it will not hinder the growth of crops, but also conducive to cooling and disease control. 2, adjust the structure of the variety, a reasonable rotation, improve the soil. Appropriately increase other cultivated crops, such as radish, potatoes, and lettuce, to cultivate the fields. If you work with rice, the effect is better. In the case of severe disease, four to five years of rotation are required. It is necessary to strengthen the soil improvement, deepen the soil, increase the use of decomposed organic fertilizers, reduce the application of acidic fertilizers, and improve the acidic soil with quicklime. 3, to improve the level of cultivation, increase the resistance of plants. The management of fertilizer and water should be reasonable to avoid excessive nitrogen fertilizer and organic fertilizer without compost, and to increase phosphorus and potassium fertilizers. To promote foliar dressing, watering must be strictly prohibited from pouring, pouring and flooding. 4, do a good job in rural cleaning. If there are gray mold, sclerotinia disease, epidemic disease, and wilt disease, during the management process, the diseased fruit, diseased leaves and diseased plants should be cleared in time to reduce the possibility of spread of pathogens and germs. 5, drug control must be due to illness, vary from day to day, mainly to prevent. (1) Nursery period. Seed disinfection work should be done before sowing, with 50% of Fomemi pairs, according to the seed weight of 0.1% seed dressing, prevent damping-down disease, carbon sickness and so on. At the same time to do a good job of bed soil and nutrient bauxite disinfection, generally 25% carbendazim, 10 grams per square meter mixed soil, remove the seedbed or alum surface, to prevent flooding. In the stage of prosthesis implantation, spraying with 75% mancozeb 500 times, it has effect on tomato early blight, eggplant brown leaf disease and cucumber anthracnose. (2) Planting live tree stage. With 25% carbendazim 250 times liquid rooting, three times in succession, especially cucumber to flowering, must be applied with 50% Suoxin 1000 times every 7-10 days, 3 times in a row. (3) During the fruiting period, it is necessary to apply pesticides according to the climate change. In case of rainy and cloudy days, it is advisable to use 30 grams of a smoked smoked cake, a standard shed (55 meters long), place 4-5, ignite before the evening work, and close the shed, and prevent downy mildew. Powdery mildew and so on. In sunny days, 75% White Bacteria 600 times liquid and 25% metalaxyl 600 times liquid can be sprayed for submersion to prevent disease. The prevention and control of gray mold during flowering results, the use of "anti-mildew" to infiltrate the point of anthers, with strong pertinence, can solve the fruit problem.

Bulb Camera

What is a smart bulb WiFi camera? The monitor, which looks like a light bulb, is commonly used for home security monitoring. The shape of the bulb is diverse, but it can not be separated from the combination of nuts. Directly connect the nut to achieve 24-hour continuous monitoring, power off free, 360 degree panoramic monitoring. Smart home bulb WiFi camera with night vision function can also see clear images in the dark night
What is the purpose of smart bulb WiFi camera?
1. The panoramic 360 degree VR monitor can monitor the whole room by installing a light bulb in one room. There is no dead angle and video can be viewed in multiple modes.
2. Smart bulb WiFi camera can be used for lighting. Even though it is a household monitor, its basic lighting functions are well protected. The voice control light on mode and the app manual light on mode are very convenient for operation.
3. Two way voice intercom function. The smart home bulb monitor has its own microphone, which can listen to and play audio. Through calling on the APP, wireless WiFi transmission is directly realized, and then played through the bulb microphone. Its role is to directly communicate with family members, and the other is to intimidate the invasion of illegal elements.
4. As a monitor, it is locally stored in the memory card, plus the backup protection of the cloud disk. Even if someone destroys the camera or even takes away the home surveillance camera, the smart home bulb WiFi camera can still view relevant videos in the cloud disk.
How to use the smart bulb WiFi camera?
Scan the QR code on the mobile phone to download the corresponding APP software, and search the corresponding software name in the app store on the iPhone.
Power on the WiFi camera of the smart home bulb, search for the WiFi hotspot signal sent by the bulb in the phone settings, and click Connect.
Open the mobile phone APP and search the camera online. This process is automatically completed. Just wait.
Configure the local WiFi name in the APP settings, fill in the password, and remote monitoring can be realized after the configuration is successful.
