How to do a good job of field irrigation and drainage during the pod stage of rapeseed flowers?

(Nongye Zhifu Wang) Irrigation and drainage during the pod stage of rapeseed flowers is very important. Rapeseed is a crop with a long growth period, a large plant body, and luxuriant branches and leaves that requires a relatively large amount of water. The stem elongation stage and flowering stage of rapeseed are the periods when it requires the most water. In the Yingtan area, the pod stage of rapeseed flowers falls in the rainy season, and if the groundwater level is relatively high, severe waterlogging damage often easily occurs. During this period, there should be neither drought nor waterlogging, and attention should be paid to clearing ditches and draining water after rain to prevent waterlogging damage.
