Therefore, it is very important to master the time and quantity of watering. At the same time, it should be mastered flexibly according to the difference of air temperature and ground temperature in different growth periods. When cultivated in the big grid, it is generally possible to irrigate 5 times and 6 times during the whole growth period. That is, three to five days after planting, slow seedling water should be watered once to promote it to slow down seedlings and produce new roots.

Watering enough water after the first topdressing can make rosette leaves grow vigorously and plants fully develop; according to specific conditions, squatting seedlings can be properly watered once, and then ploughed, and continue to squat seedlings; the fourth water should be combined with the second topdressing, this time the water must be sufficient, so that the plant growth can be accelerated and the inner leaves can bear balls quickly; in the middle of heading, combined with the third topdressing, water can be watered again to promote the ball to be big and tight. Do not fertilize or water lettuce in the late stage of heading, so as not to cause rot or cracking. Stop watering before harvest, which is beneficial to storage and transportation after harvest.
