1、 Budding period

The budding period is from the beginning of colonization to the end of the first floating leaf. During this period, the water depth is controlled at about 1-2 cm. At the same time, keep warm properly to avoid freezing death of seedlings due to low temperature

2、 Seedling stage

The seedling stage starts from the full expansion of the first floating leaf to the end of the growth of standing leaves. At this time, the water depth is controlled at about 3-5cm. More sun should be exposed every day to improve the temperature of water, which is conducive to the growth of terminal buds. After there are 5-6 leaves, you can apply some compound fertilizer. The fertilizer should not touch the leaves

3、 Leaf setting stage

From the growth of standing leaves to the appearance of flower buds. At this time, the temperature is high and the water evaporates quickly. It is necessary to add water in time to ensure that the basin is full. At the same time, more fertilizer should be applied, and compound fertilizer should be applied every 20 days. At the same time, the yellow leaves should be removed, and the petiole of the removed leaves should be higher than the water surface

4、 Flowering and fruiting stage

From the beginning of budding to the end of fruit ripening. At this time, the temperature is still very high, and the consumption of water and nutrients is very large. Fertilizer is the same as the leaf setting stage, and water should be added frequently at the same time. After the fruit matures gradually and the leaves turn yellow, the fertilizer should be reduced or stopped

5、 Dry yellow period

When the fruit is ripe, the aboveground part turns yellow and withers. At this time, keep the basin soil moist. You can cut off the dead leaves and cover it with plastic film for insulation

6、 Dormancy period

The dormancy period is after the dry and yellow period and before the germination in the second year. At this time, the main thing is to take cold prevention measures so that the plants can survive the winter safely
