Recently, the rainy weather in the south should avoid the low temperature and rainy season when planting.

According to the forecast of the Central Meteorological Observatory, from March 7th to 9th, there were small to moderate rains in the central and eastern parts of the southwestern part of the southwest, southwestern and south central areas, and south China. Heavy rain occurred in the southern part of Hunan; mountainous areas in western Xinjiang, western and eastern Tibet, and northwestern areas. There are small snow (rain) or snow (rain) in the southeast, western Sichuan Plateau, and eastern Jilin, and there is moderate to heavy snow in the northeastern part of Tibet.

March is the concentrated sowing period of early rice in the south. The early rice sowing period should be arranged reasonably. In the local early rice sowing period, the end of the cold air process should be soaked and germinated, and the temperature should be warmed up when the soil is warmed up, and the plastic film should be covered. Ensure the normal growth of seedlings.

Double-season early rice and spring corn that have been sown should pay attention to cold protection. Farmers' friends should pay attention to the local weather forecast, grab the cold-tailed warm head, timely sow and cover the agricultural film, and adopt the water temperature regulation technology. The specific method is “cold day full ditch water, cloudy and half ditch water, sunny day row. Dry water", to prevent the cold and cold damage; after the convulsions, the rain gradually increases, the low-lying rapeseed and vegetable fields should clear the ditch and drain in time, reduce the groundwater level, improve the looseness and permeability of the soil, and provide a good spring for the rape. Soil conditions promote the growth of crop roots. At the same time, seize the opportunity of the weather to warm up, classify the appropriate amount of wheat joint fertilizer and rapeseed pumping fertilizer, and strive to build a high-yield posture to capture the harvest of wheat oil.

March is also the sowing season for spring soybeans and spring peanuts. When planting, avoid the low temperature and rainy period, grasp the "cold tail warm head", grab the clear seeding, and adopt the mulching film to cover the heat preservation to ensure the seed emergence smoothly and promote the root growth and development of spring peanut and spring soybean.

Vegetables should strengthen disease prevention and control. Vegetable anchors are warm-type vegetables, which are sown and sown with plastic film to prevent seedlings from being caused by low temperature and rain, ensuring smooth seed emergence and normal growth. The management of vegetable gardens should pay attention to the problems of diseases that are easily induced by high temperature and high humidity, and strengthen the prevention and control of vegetables and pests.
