At present, most of the early rice in South China is in the stage of seedling growth, and the early rice in the south of the Yangtze River is in the stage of sowing and breeding. Among them, the area already planted in Guangdong accounts for 95% of the planting amount, Guangxi has 73%, and Hunan has planted more than 60%. The progress of planting in Fujian and Guangxi is slightly biased. SLOW. The rice in the Sichuan Basin and the central part of Yunnan was in the stage of sowing and breeding, and transplanting began in southern Yunnan. Cotton in the Yangtze River Basin is in the stage of preparation for cultivation. Dryland crops such as spring maize and spring peanuts in the southwestern region and south China are in the stage of sowing and emergence, and the progress of planting in Guizhou is slow. Spring wheat in the eastern part of Qinghai, eastern Gansu, central Yunnan and southern Ningxia is in the stage of sowing and emergence. The spring wheat planting in northern Ningxia and southern Xinjiang has basically ended.
It is expected that in the coming week, Xinjiang, Tibet River Valley, eastern Qinghai, Gansu Yuzhong and Jidong, Ningxia, southern Jiangnan, northern China, and southwestern part of the country are more suitable for spring sowing, and the southwestern part is not suitable for spring sowing. The specific weather conditions are:
From March 29 to 30, the temperature in most areas of the spring sowing area will drop by 6-8 °C, and some areas will fall by 8-12 °C. The northwestern part of the northwest, the middle and lower reaches of the Yangtze River and the north of the Yangtze River will have a northerly wind of 5-6. There are sandstorms in the southern Xinjiang Basin, the central and western Inner Mongolia, and the western part of Gansu. There are sandstorms in the local area, which are not good for spring sowing. There is a rainfall process in the south, Jianghan, Jianghuai, Jiangnan, South China, and most of Sichuan, Guizhou and other places. The precipitation is 10 to 30 mm, and some areas in the southwestern part of the southwest and the western part of the south of the Yangtze River are 50 to 90 mm. Since March 31, most of the weather in the spring sowing area has gradually improved, which is conducive to the spring broadcast.
According to the weather situation, remind everyone to pay attention to:
1. The area where the early rice has not been planted in the south should be planted in a timely manner by means of film breeding, etc., to speed up the planting schedule; the rice fields that have emerged should be strengthened in the management of the paddy field, the film is covered with cold air, and the water is properly irrigated to raise the temperature and rise. After the attention, uncover the film ventilation to avoid burning the seedlings. South China should speed up the ploughing of Honda and transplant early rice in due course.
2. In the southern region, we should plant spring corn, spring peanuts and other dryland crops in time; the cotton growing areas in the Yangtze River Basin should arrange the seedbeds well and prepare for the nutrition and nursery.
3, all parts of Yunnan should be based on drought resistance, rational allocation of water sources, to ensure that rice transplanting and spring sowing water in a season; areas with good sensation should be ploughed to sow spring crops such as spring corn.
4. The northwestern region should pay attention to avoid the windy and dusty weather. After the end of the windy and dusty weather, the spring wheat will be robbed; the mulched area should be well protected by the wind and wind.
