Current main drought prevention opinions in crops

Areas of rivers and rivers, reservoirs, and mountain ponds with sufficient water resources for rice should promote water conservation, humid irrigation, and prevent “deep waters from flooding the sky”. For the rice fields that have just been dehydrated, as long as there is water to pick, the artificial drought-floating foliar fertilizer should be taken to spray the seedlings or spray the drought-resistant functional substances to improve the drought resistance of the plants. In the open rice fields where the drought is severe, the spray can be used to spray the rice seedlings in the morning and evening, so as to reduce the water loss of the leaves and ensure the vitality of the roots, so as to achieve the effects of seedling and drought resistance. In order to improve the prevention and control of pests and diseases, in order to improve the control effect, the special agent for rice planthopper must be selected when selecting the agent.

Dry corn, summer maize should be watered, sprayed and drought-resistant. In the early stage of fertility, early autumn corn, sweet potato, autumn soybean and other dry grain crops should be timely ploughed, cut off soil capillary, and mowed. Or use straw to cover. At the same time, spray drought-tolerant agents such as dry land dragons to improve the drought resistance of crops.

Vegetables are implemented in water-saving irrigation. Vegetable bases and large vegetable growers should vigorously promote water-saving irrigation measures such as drip irrigation and sprinkler irrigation. Strengthening the management of cultivating and ground cover, timely ploughing and shallow hoeing can not only loosen the soil, improve the root growth environment, but also cut off the soil capillary and reduce the loss of soil moisture. Covering the soil with straw or straw can lock the soil moisture, lower the soil temperature, and reduce water evaporation.

Fruits, tea orchards, and tea gardens are covered with mountain gardens to prevent direct sunlight and reduce water evaporation. Fresh fruit peaches, plums, pears, and fruit melons are harvested in time to reduce economic losses. Pay attention to pest control, citrus attention to rust tick, red spider control; tea to do a good job of small green leaf mites to reduce production losses.

After the weather has rained, the land has been replanted, and the fast-growing vegetables such as autumn corn, autumn sweet potato, autumn potato or radish, and cabbage are promptly reorganized to stop the abandonment of cultivated land.
