Rice transplanting is an important part of rice planting, and the following points need to be paid attention to in order to ensure the survival rate and growth quality of seedlings.
First of all, it is necessary to combine the actual situation of rice seedlings in cold regions, and the leaf age should reach 31-3.At the 5-leaf stage, the seedling age of the blanket seedling tray reaches more than 35 days, and the root packing is better at this time, so it can be grabbed for agricultural time and planted early at the appropriate time.
Secondly, it is necessary to choose the appropriate time for transplanting. When the climate is suitable, plant rice as early as possible to make the most of the growing season and resources. However, if the temperature is too low or the weather is rainy, it is necessary to delay the transplanting time appropriately to avoid adversely affecting the seedlings.
Third, we should pay attention to the density and method of transplanting. At the right density, seedlings can make better use of light and nutrients to promote growth. At the same time, the seedlings should be kept upright and of moderate depth when transplanting, so as to facilitate root growth and tillering.
Finally, pay attention to the prevention and control of pests and diseases. After transplanting, pest control should be carried out in time to prevent the impact of pests and diseases on the seedlings. At the same time, it is also necessary to strengthen field management to maintain water and nutrients in the field to promote the growth and development of seedlings.
In short, rice transplanting in cold regions needs to be combined with the actual situation, choose the appropriate time and method for transplanting, and strengthen field management and pest control to ensure the survival rate and growth quality of seedlings.
