New Aquatic Vegetable Planting Model Overcomes Continuous Cropping Obstacle

In recent years, the Jiangsu Province Aquatic Vegetable Efficient Production Innovation Technology Team, through collaborative research, has extensively carried out cooperation, exchange, integration and demonstration among collaborative groups of ecological and efficient planting models such as "melon and fruit vegetables - water caltrop", "early spring greenhouse water spinach - late autumn melon and fruit vegetables", and facility "mushroom - aquatic - dryland" ecological cultivation. These not only effectively controlled the continuous cropping obstacle of facility vegetables, but also, through off-season cultivation, greatly improved the production efficiency of facility vegetables. In some areas, the 3-month aquatic vegetable crop rotation achieved a per-mu benefit of over 20,000 yuan.

At present, greenhouse lotus root, arrowhead, water caltrop and others are planted on a large scale of over 10,000 mu in Jinhu, Baoying, Jiangyan, Rugao, Yandu, Xinghua, Jingjiang, Funing and other places. New ecological and efficient models such as "strawberry - water caltrop" in Lishui District of Nanjing, "dryland vegetables - water spinach" in multiple districts and cities of Suzhou, "spring greenhouse watermelon - direct-seeded second crop arrowhead" in Dongtai of Yancheng, "milk vetch - water caltrop" in Yangzhong of Zhenjiang, and "spring greenhouse arrowhead - rice" in Jiangyan District of Taizhou have been promoted and applied on a large scale. In water-rich areas south of the Huaihe River Basin, the annual cultivation area has reached over 50,000 mu.
