The recent rainfall intensity is strong and lasts for a long time. Heavy rain has caused large areas of waterlogging all over the country. Some vegetable bases have experienced varying degrees of damage. Next, there will be a heavy rainfall process. In this regard, it is recommended to take the following five measures to take measures: First, grab the drain. Timely grab row, lower groundwater level, timely dredge the three ditch, eliminate waterlogging, fast discharge under the rain, rain and ditch dry, to prevent the suffocation of vegetables due to water and waterlogging and death, avoid vegetables early stop the garden. 1, timely righting vegetable strains. To uproot fallen vegetables, reduce the phenomenon of mutual squeeze, and properly cultivate the roots. 3, timely sprinkle grass ash. Appropriate vegetation ash can absorb water, reduce soil moisture, increase nutrients, improve the environment, and prevent disease, convenient sources in rural areas should be promptly applied. 4, timely cultivation of loose soil. After the rain, the soil is compacted, and when the soil is a little dry, cultivating tillage is performed to improve the soil structure and enhance the vitality of the root system. 5, to promote shelter cultivation. The use of plastic films, shade nets and other materials covering the top of the greenhouse can not only avoid direct rainwater raid, but also can effectively improve the climate of the shed, temperature, light, moisture, gas and other microclimate, reduce the number of drug control and dosage. Third, rush to prevent and control. 1, ecological regulation. First, pay attention to dredge the Sangou (Weigou, Xianggou, Yaogou), timely drainage, prevent the accumulation of water in the field. The second is to pay attention to pruning, to ensure that the field ventilation and humidity. Third, we should pay attention to the removal of weeds and diseased plants in the fields, fields, and reduce the sources of diseases and insect pests. 2, biological control. First, the use of biological missiles to prevent leguminosae, Spodoptera litura, beet armyworm, diamondback moth and other lepidopteran pests, 4 to 6 mu biological missiles. The second is the application of attractants to control Spodoptera litura, Spodoptera exigua. 3, physical control. The first is manual removal of Spodoptera litura, Spodoptera exigua eggs or artificial capture. The second is the use of insect traps. The third is to use silver worms to repel insects such as whitefly. 4, chemical regulation. The control of powdery mildew, anthrax, coal mycosis, and rust can be done with 30% carbendazim 1500 times or 10% oxalimonazole (1500 times, or 70% thiophanate-methyl thiophanate-methyl) 700 Alternating liquid spray; For the prevention of downy mildew, the disease can be selected Propozoone (72.2% Prec) 800 times or 72% Kelu 500 times or Trichoderma Mn Zn (Golden) WP 500 ~ 800 times liquid; Fusarium wilt can be controlled with mycotoxin (Green Hunter No. 1) 3000 times solution or 70% thiophanate-methyl (methyl thiophanate) Irrigation Irrigation; root can be controlled 72% Agricultural streptomycin WP or 72% neophytin 3000 ~ 4000 times spray; Prevention Spodoptera litura, beet armyworm can use indoxacarb (15% hits) 3750 times or 1% methional salt 2000 ~ 2500 times solution or acetamiprid (5% Supio) 1500 times solution or chlorfenapyr (10% dilute) 2000 times solution, etc. alternately spray; Bean Scorpion can be used to prevent 2,000 times 2500 times Acetidone (5% CPT) 1500 times or more racomycin (2.5% dish) 1500~2000 times or Bt powder 500 times alternately; control of Bemisia tabaci can use 4% Avicidium 2000 times fluid or 2.5% 800 times solution of bifenthrin or 0.3% matrine 1000 times solution spray alternately; 2000 times more resistant to Plutella xylostella (2.5% dish), 1500-2000 times solution or acetamiprid (5% Supio) Liquid or 1% methacrylate salt 2000 ~ 2500 times or indoxacarb (15% hits) 3750 times or 1.8% abamectin 2000 times spray control. Fourth, grab the harvest. To timely harvest mature or mature vegetables, timely supply the market, reduce losses, increase income, and stabilize prices. Fifth, sowing sowing 1, timely rush to broadcast fast lettuce, so that staged sowing, a balanced listing, 30 to 40 days after the broadcast can supply the market. 2, timely change, picking up the season can carry out the autumn vegetables seedlings or live, and timely change.

Second, grab management
2, timely spraying foliar fertilizer. After the heavy rain, the ability of vegetable roots to absorb water and fertilizers is poor. In this case, foliar fertilizers should be sprayed in time. Generally, 0.2% potassium dihydrogen phosphate + 0.5% urea can be used, which can quickly restore the vitality of vegetables.
The fourth is to increase phosphorus and potassium fertilizers to increase plant disease resistance.
