At this time, the temperature is neither too high nor too low, which is suitable for seed germination. : Rice can only be sown at a suitable temperature. The ambient temperature should be above 7 degrees, and the ground temperature of 5cm should be between 8 degrees and 10 degrees. Seeds should be sown on the soil, covered with 0.5~ 1cm thick nutrient fine soil and watered once to keep the soil slightly wet.

Rice sowing method

Rice seeds need to be watered in time after sowing, and transplanted to the field after germination. The transplanting depth should be kept at about 1.5cm, and the spacing should be well controlled, so that there can be no uneven height and different depths. If there is more precipitation in rainy season, drainage measures should be taken. If the temperature is high in summer, you need to water it in time.
