Key Points for Rice Cultivation Management During Spring Cold Waves
I. Characteristics of Cold Wave Disasters Due to the invasion of cold air, when the temperature drops sharply by more than 10°C within 24 hours, and the minimum temperature within that day is below 5°C, it is called a cold wave. In the middle and lower reaches of the Yangtze River, when strong cold air moves southward and causes the temperature to drop by more than 10°C within 48 hours, it is also called a cold wave. Cold waves generally occur in spring and autumn, with spring being the most common, and spring cold waves mostly occur from March to May. Cold waves mainly cause seed rot, seedling rot and dead seedlings during the rice seedling stage. II. Rice Cultivation Manage

What measures promote rice root development?
1. Sow early at the right time. When the temperature stabilizes at 5°C, begin sowing and raising seedlings; do not raise seedlings for the May crop. When the temperature stabilizes at 13°C, begin transplanting; do not transplant for the June crop. Transplant during the high-yield period to gain accumulated temperature, which is beneficial to root development. 2. Prepare the land carefully and create the conditions. Do a good job of plowing and rotary tilling; generally the plowing depth is 20 cm and the rotary tilling depth is 14 cm. Keep the plowing or rotary tilling depth uniform, so that the mud is not exposed even in water an inch deep, creating the conditions for root development. 3. Strengthen management and promote development. First, seedling-field management: control the temperature well, water reasonably, spray fertilizer on the leaves, and prevent

Current Technical Guidance on Rice Seedbed Management
Currently, some early-sowing areas are affected by sharp temperature changes caused by cold waves, and rice seedlings have suffered frost damage to varying degrees, which has affected seedbed management and will delay the transplanting process to a certain extent. In order to improve seedbed management and reduce low-temperature damage, the following technical guidance on seedbed management is hereby proposed. 1. Small-tunnel seedling cultivation. According to the weather forecast, add more covering material on the tunnel and keep it sealed for insulation. In case of frost, candles can be lit or smoke can be generated inside the tunnel to raise the temperature and prevent freezing. For medium and large tunnel seedling cultivation, ventilation should be reduced or even stopped. Straw curtains should be placed around the tunnel, plastic film should be laid flat inside the tunnel,

How should current rice production be managed? Technical guidance is here
At present, China's early rice production has entered the late growth stage. In southern Guangdong and Guangxi, the vast majority of early rice has entered the grain-filling stage, and a small portion has entered the maturity stage; in central Guangdong and Guangxi, heading has begun; in northern Guangdong and Guangxi, it has entered the initial heading stage to heading stage. Early rice in the middle and lower reaches of the Yangtze River has entered the milk-ripe stage and is expected to begin harvesting around July 10. Single-season rice in Northeast China is in the tillering peak stage, young panicle differentiation stage and booting stage from south to north; mid-season rice in the winter paddy field areas of Southwest China is in the booting stage, the river valley and hilly areas have begun young panicle differentiation, and the Chengdu Plain area is in the field-drying stage at the maximum tiller stage
