Recently, the Lin'an City of Zhejiang Province has experienced heavy rains. The Linan Meteorological Observatory issued a yellow rain warning signal at 23:08 on the 14th. Due to the long rainfall period and large rainfall, the water in the crop fields is serious. After the rainstorm, All localities should take effective remedial measures in a timely manner to reduce the loss of disasters.
Vegetable disaster recovery measures
1. Dredge the ditch. Deepen the drainage ditch to make the ditch clear, minimize the water level in the field and the shed, and reduce the occurrence of root diseases such as roots and roots caused by lack of oxygen in the water.
2. Ventilation and humidity control. The shed vegetable should be ventilated and drained into the shed. For the shed with too high humidity, it is recommended to use the dry and fine soil moisture absorption method to control the humidity inside the shed.
3. Chemical control. Prevention of seedling disease should be regularly controlled with oral medicine once every 7 days. If there is sporadic disease, it should be sprayed and controlled in time to make full use of the rain stop gap for chemical control. The disease can be controlled by 64% antivirus WP WP 600 times, or Plex water 800 times solution, or 95% carbaryl powder 300 times solution;
Vegetable gray mold: 50% procymidone WP 2000 times solution, 30% pyrimethanil (Smet) suspension 1000 times solution, 50% vinyl bacteria nuclear (Nongliling) dry suspension agent 1500 A drug such as a liquid is sprayed at the beginning of the disease. Aerosols or dusts can also be used in the shed. Since Botrytis cinerea is highly susceptible to drug resistance, it is necessary to pay attention to the rotation of drugs, thereby avoiding or delaying the development of drug resistance and improving the control effect against gray mold.
Solanum fruit blight: In the early stage of the disease, 80% sensitized zinc 500 times solution and 75% chlorothalonil 800 times solution can be used for spray control, and attention should be paid to rotation. The prevention and treatment of early blight must be early, generally 1 day or so, and should be controlled twice or so continuously.
Orchard post-disaster remedies
1. Wash the branches and leaves. The fruit trees that are immersed in the mud and water are removed from the water after the rain stops, and the debris and mud stains on the technical leaves are removed to keep the leaves clean.
2. Fuzheng fruit trees. If the tree is washed down, washed, or washed away due to soil erosion, the fruit trees are exposed to roots and roots. After the disaster, the fruit trees should be fixed in time, and the roots should be soiled and protected by brackets.
3. Clear ditch drainage. For flooded orchards, clear and drain the drainage ditches in time, and quickly eliminate the accumulated water in the garden to avoid the death of fruit trees due to long-term water accumulation.
4. Temporarily loose soil. After flooding, the field is easy to cause soil compaction, which is easy to cause root hypoxia. When the surface soil of the garden is basically dry, it is necessary to carry out shallow tillage and soil release in time to restore soil permeability and promote new roots.
5. Topdressing fertilizer. The roots of fruit trees affected by floods have different degrees of damage, and the absorption of nutrients is affected. Therefore, it is necessary to supplement the nutrition by spraying foliar fertilizer, and the foliar fertilizer is mainly organic nutrition. The soil is mainly applied to the quick-acting fertilizer. Depending on the disaster of the tree, the fertilizer is generally applied 2-3 times.
6. Moderate trimming. Moderate pruning should be carried out in order to reduce the evaporation of water from the branches and the consumption of nutrients in the tree. The amount of pruning is determined according to the degree of damage. In addition to heavy shearing, the tree with heavy damage should also remove some or all of the fruit.
7. Spray protection. Various pests and diseases should be induced after the disaster. Management should be based on prevention. Commonly used pesticides include Bordeaux mixture, Dasheng M-45, carbendazim, methyl thiophanate, and spray.
Rice disaster remedy
The flood disaster is in the single-season rice breeding period. A considerable number of polders are flooded or destroyed. After the rainstorm, the ditch drainage should be done in time, and all rice seedlings should be protected against bacterial blight, striped blight and ash. Fly cockroaches, prevent it in the first place, use 20% leaf green double 100g +25% sputum 50g +25% shunwei 100g water 50kg spray, and see seedling fertilizer; top dressing, disease prevention and control Once, improve the quality of the seedlings and insist on bringing the medicine to the field. For the paddy fields that are flooded in the field, it is necessary to drain, support and clean the field in time; for the heavily destroyed polders, timely purchase and replanting, you can choose noisy: Youyou No.1, Noisy: Qianyou No.1, IIyou92 and other high-yield and stable varieties. Field transplanting and field management should promote: transplanting seedlings with short seedling age, planting less plants, increasing the application of organic fertilizers and paying attention to panicle fertilizer; focusing on the promotion of shallow-wet irrigation, comprehensive control of pests and diseases, etc. .
Post-disaster remedies for corn
Do a good job of clearing the ditch drainage in the spring corn field, and the lodging plants should be strengthened and strengthened in time to cultivate the soil, restore the growth, and improve the plant resistance. Pay attention to the prevention of pests such as corn borer, large leaf spot, and rust. Corn horns were treated with phoxim mixed with toxic sulphur or with insecticidal double spray to control corn mash; during the silking stage, mancozeb was used to control corn leaf spot disease; and between 6 and 7 months, rust rust was used to prevent corn rust. The damaged land can be replanted into autumn corn. The varieties include Nongda 108 and Biandan 18, and the sowing date is in the middle and late July. It prevents the filaments from drying up during the silking period from July to August, which affects the pollen rate. Baldness or grain is not true.
Soybean disaster recovery measures
For spring soybeans planted in April, it is necessary to do field management such as cultivating weeding, locust control, and water-fertilizer cultivation during flowering, timely clearing the ditch drainage, and spraying 10% imidacloprid 2000 times liquid to control aphids, flowering In the general period, the application of urea is 3-5 kg, and the amount of fertilizer is determined according to the condition of the seedling. At present, it is the appropriate period for planting summer soybeans. It is necessary to choose high-quality and good-quality seeds of Kaohsiung No. 2 and June and half, and that it is reasonably densely planted. Generally, the planting is 7000-8000, and the seedlings are about 20,000, and the seedlings are fixed in time.
Sangyuan post-disaster remedy
Firstly, establish or dredge the drainage system in the mulberry garden to avoid the mulberry tree soaking in the water for a long time, and the rotten root phenomenon occurs. Secondly, the mulberry garden that has been washed away by the soil must be used to support the mulberry trees, and the soil should be filled to fill the roots. To accumulate the mulberry gardens, the silt should be removed. It is also necessary to plow the mulberry garden in time to enhance the permeability of the soil. Apply a certain amount of quick-acting nitrogen fertilizer when tilling.
