How should the water layer be regulated at different growth stages of shallow-water lotus root?
The suitable water level for shallow-water lotus root is 10-20 cm, and the maximum water depth it can tolerate is 50 cm. In cultivation, the water layer must be well regulated according to the different growth stages of shallow-water lotus root. The general principle of water layer management for shallow-water lotus root is shallow at the front, deep in the middle, and shallow at the back. After planting the lotus root, when the standing leaves appear, maintain a shallow water layer of 4-7 cm to increase soil temperature and promote sprouting. As the stems and leaves grow vigorously, gradually deepen the water layer to 12-15 cm. After the terminal leaves appear, the plant begins to form lotus root, and the water layer is gradually lowered to a depth of 4-7 cm to promote lotus root formation.

Spraying potato plants with paclobutrazol helps regulate crop growth
Deformed potato tubers are mainly caused during the tuber enlargement stage by adverse conditions such as high temperature and drought, which inhibit the growth of the expanding tubers and temporarily halt their growth. Later, due to rainfall or irrigation, the growing conditions are restored, and the tubers resume growth accordingly. At this point, the organic nutrients entering the tubers, at the buds with strong physiological activity...
