浙江省是全国西兰花主产区,年种植面积15万亩(10 000公顷),但连续种植多年后连作障碍加重,影响西兰花产量和效益。近年来,各地创新农作制度与生产经营机制,建立示范基地,推广“西兰花—早稻”轮作模式,年推广面积近5万亩(3 333公顷),占西兰花面积的1/3。实施该轮作模式,促使粮食和蔬菜生产互惠互利,改善和提高了基地生产功能,提升了技术装
Zhejiang Province is the main producing area of broccoli in China. The annual planting area is 150,000 mu (10,000 hectares). However, the continual cropping obstacle is aggravated after many years of continuous planting, affecting the yield and benefits of broccoli. In recent years, various localities have innovated their farming systems and production and management mechanisms, established demonstration bases and promoted “Broccoli-Early Rice” rotation mode, with an annual promotion area of nearly 50,000 mu (3,333 hectares), accounting for 1/3 of that of broccoli . The implementation of the rotation model will promote the mutual benefits of food and vegetable production, improve and enhance the base production functions and upgrade the technical equipment
