This spring, the temperature in Antu County, Jilin Province is more than 3 degrees above the calendar year. Rapid thawing and high temperature are conducive to the preparation of rice seedlings. However, at present many farmers have the mentality of using an opportune moment to sow seeds. This will have an adverse effect on the next rice transplanting effort and this year's rice production.
Jilin rice expert Yan Guangbin suggested:
First, the current high temperature of the climate does not mean that it will be beneficial to seedbed management during the future seedling raising period. Once the seedlings exceed 1.5 leaves, there will be serious management problems.
Secondly, after the rice seedlings grow to a certain degree, the best transplanting time for seedlings with high yields is limited. If the seedlings exceed this optimal time, they will become young and old seedlings, and seedlings will inevitably have large seedlings, which will seriously affect rice yield. .
Thirdly, the seeding rate of flat-stem transplanting seedlings is too large, the quality of seedlings is weak, and the ability to resist low temperature after transplanting is even worse. The best time for the smashing period is shorter and the seedling raising is not conducive to the slow seedling growth and growth of rice.
Therefore, the vast majority of farmers in the active preparation for cultivation must at the same time according to transplanting area, seedling nursery methods, in particular, according to the size of the amount of seeding and the time of transplanting is expected to grasp the sowing time.
