The use of plastic sheds to cover plastic films for the cultivation of lotus roots will enable early listing of lotus roots and significant economic benefits.
è—• species selection: Elian No. 1 was cultivated by Wuhan Institute of Vegetables, main section 6~7 section, 1.3 meters long, 6.5cm thick, 15~20cm deep into the mud, light yellow skin, open field cultivation in mid-July Receive tenderness. E Lian No. 3 was also cultivated at the Wuhan Institute of Vegetable Research. The main section was 5-6 sections, 1.2 meters long, 7cm thick, 20cm deep into the mud, and more than 3kg per branch. The epidermis was light yellow-white, with open field cultivation. In mid-July, it will receive tender food. Calyx is a species of precocious fleas in our province.

The height of the shed is 1.5 meters, width is 3 meters, length is 20-30 meters, the distance between the arch sheds is 40 centimeters, and the top and two waists are set with tie rods. The plastic film is used to cover the foot with mud and the thickness is 0.6mm and the width is 5 meters. Compaction.
Shed management: 50% of the leaves are not fertilized before they grow, but care must be taken to keep the soil in a slime state.
