The typhoon "Mangosteen" has already landed in Guangzhou, and its destructive power is very large. In addition to strong winds, the typhoon weather is also very rainy. The typhoon and rain weather will undoubtedly cause inevitable damage to crops. So, what are the farmers doing in the face of typhoon and rain? Let's learn about the prevention and remedial measures of crops before and after the storm.
First, rice, vegetables and other crops before the typhoon storm prevention measures
1. Tianyang dredges the ditch and opens the drainage ditch in the field to ensure smooth irrigation and drainage;
2. Field crops such as rice, melons and vegetables are mature and timely organized to collect;
3. If the melons are being seeded, it is necessary to build a small arch shed with a film and a shade net for reinforcement protection. If the terrain is low, the seedlings should be transferred to the heights or at home;
4. Inspection and reinforcement of production facilities such as greenhouses.
2. Field management measures after typhoon storms
1. Rice management measures
Clearing drainage
After the typhoon and heavy rain, clear the ditch and drain in time to ensure smooth drainage, reduce the possible accumulation of water, and clean the flooded leaves during drainage to promote the recovery of crop roots and plants as soon as possible.
2. Grab
Mature rice should be harvested in time.
3. Lodging rice
Rice that is not mature and lodging should be mobilized by farmers. Bundling by means of ropes, etc., to prevent the occurrence of immersion by water.
2, melon management measures
Clearing drainage
It is necessary to dredge the ditch in time, reduce the water level, and eliminate the water in the vegetable fields.
2. Grab
If the vegetable fields are flooded and the vegetables are damaged, the affected vegetables that have a listing value should be actively harvested, seized, and reduced.
3. Strengthen management
The growing melons and vegetables should be used to strengthen the plants, remove the yellow old leaves, and clean the fields. After the heavy rain, the surface soil of the vegetable field is seriously drained. It is necessary to cultivate the soil in time to avoid the exposure of the roots. After the weather improves, the soil will be loosened in time to increase the permeability of the soil, prevent soil compaction and affect the growth of vegetables. At the same time, timely apply 1-2 times of quick-acting fertilizer, applying 4-5 kg ​​of urea per acre. The root dressing was carried out with 0.15% urea and 0.2% potassium dihydrogen phosphate to ensure the normal growth of the vegetables.
4. Strengthen prevention and control of pests and diseases
After the storm, the melons and vegetables are injured, the disease is easy to invade from the wound, and the humidity in the field is high. The most common diseases are bacterial leaf spot, blight, downy mildew, bacterial wilt, blight, and stagnation. After the weather improves, it is necessary to use 80% mancozeb WP 500 times + 2% spring leimycin (addition of rice) water 500 times spray prevention; when the disease occurs, the following methods can be adopted to prevent and control:
(1) Bacterial leaf (horn) spot can be selected with 2% spring lycopene water agent (added rice) 500 times, 27.12% basic copper sulfate suspension agent (copper noble) 1000 times, 46% copper hydroxide water dispersion particles Agent (can kill 3000) 1500 times or 77% copper calcium sulphate wettable powder (Doning) 600 times foliar spray (previously use copper preparation when the humidity is high).
(2) Bacterial disease, downy mildew, squatting disease, etc. 68.75% fluorobacteria · downy mildew suspension (silver method) 1000 times, 72.2% creamy chlorinated saline solution (Pulke) 1000 times, 44% The spermatozoa and chlorothalonil suspension (Feige) 600 times and other drugs are sprayed.
(3) Bacterial wilt, blight and other diseases, after the weather improves, you can use 11% refined A · a · azin seed coating agent (Baolu) 1000 times + 2% spring lycopene water (added rice) 500 Double or Bacillus subtilis (Qiaosenhe) 500 times +20% amino acid (more roots) 300 times continuous rooting 2-3 times.
The above is the prevention and remedial measures of crops before and after the typhoon storms compiled by Huinong. The above pharmacy program is for reference only and I hope to help everyone.
