Prevention and Treatment of Common Diseases at Seedling Stage of Rice
Blight (yew): Blight is closely related to seeding rate in the presence of growth regulators. Brooming is easily achieved when the seeding rate exceeds 300 g/m2. The symptoms of blight are the dwarfing, yellowing, new roots, or lack of roots. After the diseased seedlings have been rooted and explanted, the connection between the roots and the stems is opened to see the center of the stems. If it turns black, it is a blight. Blight often leaves the dead leaves earlier than the lower leaves. Once you have found a blight, you should fight it immediately. Bacterial wilt: A form of blight, which is mainly caused by improper management of seedbeds. Ventilation at seedling stage is low, bed temperature is high, and watering causes more rice seedlings, and the seedlings on the ground are too large. The water supply capacity of the roots in the underground is less than the evaporation of shoots and leaves from the shoots, and it is easy to get bacterial wilt in severe cases. The method of prevention and control: Usually the seedbed is ventilated, ventilated, ventilated, or watered at noon. If the mixture of blue-green and dry-yellow occurs, it should be managed in accordance with the method of preventing blight, and at the same time, it should be sprayed with an agent for controlling blight. Burning seedlings: Burning seedlings is caused by excessive fertilization. Excessive fertilization is often uneven, no emergence or emergence after the needle, not long, generally small roots, black, do not take root. Under the premise of being free from frost damage, it is often watered during the day, and the film is uncovered, then watered and then uncovered, and washed repeatedly to remove some of the fertilizer from the seedbed, promote rooting, and normal management of the rice seedlings after the emergence of new roots. Roasted seedlings: Roasted seedlings are the phenomenon of rice stems and leaves yellowing when the temperature is too high. Most of the roasted seedlings are grown on seedbeds with plastic film. Do not easily destroy seedlings when roasted seedlings are produced. After topdressing 50 g/m2 of ammonium sulfate and rooting agent, maintain the temperature below 30°C, ensure the temperature and humidity as much as possible, and promote the growth of rice seedlings. Enter normal management. Frozen seedlings: When the temperature of rice is below -3°C before emergence, it is prone to frost damage. The bigger the seedlings are, the greater the degree of frost damage is. The frozen rice seedlings begin to turn into a water-soaked thick green color and turn yellow and white after sun exposure. When the temperature is expected to reach 0°C, the first day of watering can effectively reduce the degree of frost damage.
Indoor monitor is one part of intercom system, and it is also a very important part. Video Door Phone and indoor monitor are connected in the same POE Switch to realize information transmission through local area network (LAN). When the visitor calls the indoor monitor on the video door phone, the indoor monitor will receive the call information in the corresponding apartment, the resident can check the situation at the door and see who is coming through the indoor monitor, and then can choose to talk with the visitor or not.
