Permeable ventilation in paddy fields is not only water-permeable, in order to facilitate seed germination and emergence, but also to ventilate, so that the seedlings can take root and grow, which can effectively prevent rot. The specific approach: first the rice field cultivating the whole fine, from the ditch to do squat, apply enough base fertilizer, the smashing of the smashing mud, preliminary smashing; then soaked in water, and then further leveling the smashing.
The temperature required for the normal emergence of a rice seedling is 15°C. Therefore, when the temperature rises to 12°C, it is advisable to plant seedlings when exposed to open soil. If the eel is raised earlier, the temperature is lower, and the growth of rice seedlings is slower, the eel age should be longer; if the eel is late, the temperature is higher, rice seedlings grow faster, and the eel age should be shorter.
Cultivating strong and strong people is the basis for high yield of rice, and it is also a prerequisite for preventing rotting. Wet breeding methods can be used to cultivate age-appropriate bragging. In the up seedling stage, irrigation is generally conducted only in the Tiantiangou, and the field surface is kept moist and aeration is not performed, but the seed is quickly rooted and established. During the rooting period, it is necessary to have a flexible understanding of the water layer and prevent freezing and sun protection. Keep the water in Putian and ventilate it to protect the seedlings.
