After the rainstorm, the management of vegetables caught the "five grabs"
In view of the recent strong precipitation intensity and long duration, heavy rain caused a large area of ​​waterlogging on vegetable fields, and some vegetable bases suffered from different degrees of damage. In the following, there may be a process of heavy rainfall, and the following “five grabs†response measures should be made at the moment –
Grab the drainage
Timely dredge the ditch in the vegetable field, remove the waterlogging, make the rain fast, drain the ditch, prevent the suffocation of vegetables caused by water and waterlogging, and prevent the vegetables from leaving the park early.
Grab management
First, timely support the vegetable plant. It is necessary to correct the lodging of the vegetables, reduce the phenomenon of mutual extrusion, and properly cultivate the roots. The second is to spray foliar fertilizer in time. After the rainstorm, the roots of the vegetables are poorly capable of absorbing water and fertilizer. At this time, the foliar fertilizer should be sprayed in time. Generally, 0.2% potassium dihydrogen phosphate + 0.5% urea solution can be used to make the vegetables quickly recover. The third is to scatter the wood ash in time. Spreading grass ash can absorb water, reduce soil moisture, increase nutrients, improve the environment, and prevent diseases. The convenience of rural sources should be applied in time. The fourth is to cultivate the loose soil in time. After the rain, the soil is compacted. When the soil is slightly dry, the soil is ploughed to improve the soil structure and improve the root activity. The fifth is to promote rain-proof cultivation. Covering the top of the greenhouse with plastic film, shading net and other materials can not only avoid the direct germination of rainwater, but also effectively improve the temperature, light, humidity, gas and other microclimates in the shed, and reduce the number of chemical control and the amount of drug used.
Grab the control of
Ecological regulation. First, pay attention to dredge the lateral ditch, the ditches, and the back ditch, and timely discharge the water to prevent water accumulation in the field. The second is to pay attention to the pruning and forks to ensure that the field is ventilated and dehumidified. The third is to pay attention to clearing the fields, weeds and diseased plants in the field, and reducing the source of pests and diseases. The fourth is to increase the application of phosphorus and potassium fertilizer to increase plant disease resistance.
Biological control. First, the application of biological missiles to control lepidopteran pests such as Beans, Spodoptera, Spodoptera, Plutella xylostella, and 4-6 biological missiles. The second is the application of attractants to control Spodoptera litura and Spodoptera exigua.
Physical control. First, artificial removal of Spodoptera litura, beet armyworm egg mass or artificial capture. The second is to use insecticidal lamps to trap. The third is to use silver-colored insect-proof belts to repel pests such as whitefly.
Chemical regulation. First, the prevention and control of powdery mildew, anthracnose, coal mold, rust can be 30% ether oxystrobin 1500 times solution or 10% oxazolidine 1500 times solution or 70% methyl thiophanate 700 times solution alternately spray; For mildew and disease, 72.2% Plex 800 times solution or 72% gram lot 500 times solution or dystrophic manganese Zn-Zn wettable powder 500-800 times solution can be used. The third is to control the blight with Greenheng No. 1 3000 times solution. Or 70% methyl thiophanate 700 times liquid irrigation; the fourth is to prevent bacterial keratosis 72% agricultural streptomycin WP or 72% neomycin 3,000-4000 times liquid spray; Spodoptera exigua, beet armyworm can use 3700 times solution of indoxacarb or 1% Avi 2000-2500 times liquid or acetamiprid 1500 times liquid or worm nitrile 2000 times liquid, etc. 1% of the calcium salt 2000-2500 times liquid or acetamiprid 1500 times liquid or doxorubicin 1500-2000 times liquid or Bt powder 500 times liquid alternately controlled; seven is the control of whitefly, 4% of avermectinè„’2000 times liquid or 2.5% bifenthrin 800 times solution or 0.3% matrine 1000 times solution alternately sprayed; eight is used to control Plutella xylostella 1500-2000 times liquid or acetamiprid 200 0 times liquid or 1% methyl salt 2000-2500 times liquid or indoxacarb 3750 times liquid or 1.8% avermectin 2000 times liquid spray control.
Grab the harvest
The mature or soon-to-mature vegetables should be harvested in time and put on the market for sale, thereby reducing losses, increasing income, and stabilizing prices.
Rescue seedlings
First, it is necessary to promptly broadcast fast-growing vegetables to the harvested fields, and strive to be listed 30-40 days after the broadcast.
The second is to carry out the change in time, catch the season to carry out the seedlings or live broadcast of autumn vegetables, to ensure that the affected fields do not reduce production and do not reduce the income.
