1. when is the spring ploughing in the south?
China has a vast territory and abundant resources, and the time of spring ploughing varies from place to place. The time of spring ploughing in the south is earlier, and it is postponed in turn to the north. The farther north, the later the spring ploughing season. Generally speaking, the temperature in the south rises rapidly. Spring ploughing begins in late February and early rice is sown in March every year. The general time of spring ploughing in northern China should be from March to April, and the specific sowing time is different because of the temperature, moisture and other factors in the region.
2. Precautions for busy farming in spring
1. Weather
Pay attention to the ground temperature in real time, and then choose sowing when it reaches the suitable sowing temperature. When preparing for spring ploughing, pay attention to the recent weather and wait until the recent weather is stable before spring ploughing. Before spring ploughing, pay attention to the weather forecast, and there will be no weather such as cooling, strong wind and rainy weather that will affect seedling emergence in the near future.
2. Preparation of agricultural machinery
Before spring ploughing, maintain agricultural machinery to avoid delaying farming time due to machinery during busy farming. Before spring ploughing, conduct a comprehensive inspection and maintenance as required. Mechanical inspection such as ploughing, grinding, sowing, etc., to avoid negligence and delay the farming season, and the oil for spring ploughing of agricultural machinery should be clean.
3. Soil moisture
Remove the residual water in low-lying areas in time to avoid part of the soil being dry and part wet. Pay attention to moisture content and avoid low germination rate of seeds caused by too wet or too dry soil.
4. Agricultural materials
To prepare fertilizer for spring ploughing, it is necessary to select suitable fertilizer varieties according to the characteristics of fertilizer absorption of crops, which can not only give full play to fertilizer efficiency, but also reduce production costs and obtain high yield. Look at the packaging before buying fertilizer. According to the national standards, the product name, nutrient content, implementation standard, grade, trademark, net weight, factory name, address and production license number must be indicated on the fertilizer packaging bag. Pay attention to the date of production of seeds, and the germination rate of seeds stored for a long time is low.
