南通市桑园冬季间作高效模式及综合栽培技术

围绕桑园综合开发利用，开展桑园冬季间作试验示范研究，研发出适合南通地区桑园冬季间作的3 型（产品增收型、桑园培肥型和农牧结合型）4 类（间作蔬菜类、间作草莓类、间作绿肥类和间作牧草类）共20 种主体种植模式；针对确定的主体模式进行适宜品种筛选及更新技术；集成配套桑园冬季间作优质高产、轻简增效和病虫综合防控等关键技术，推进桑园冬季间作标准化管理。根据南通市不同区域生产特点与市场需求，研究并确立了基于盐渍加工类蔬菜、速冻保鲜类蔬菜、超市型鲜品类果蔬、用于畜禽饲草和培肥改土类绿肥5 个目标市场的模式优势区域，旨在对推动南通市蚕桑、蔬菜等主导产业持续高效协调发展，江苏省及长江中下游地区的桑园综合开发利用起到一定的引领作用。

Efficient Mode and Integrated Cultivation of Winter Intercropping in Mulberry Field in Nantong

The study of winter intercropping in mulberry field was carried out on the synthetical development and utilization of mulberry field. 20 kinds of modes which were suitable for winter intercropping in mulberry field were studied. The 20 kinds of modes included 3 types (product raise type, mulberry field fertilizer type, agriculture and animal husbandry combination type), and 4 classes (intercropping vegetables class, intercropping strawberry class, interplanting green manure class and intercropping forage class). We selected suitable varieties and updated technologies for the main mode. We adopted key technologies including good quality and high yield, convenience and efficiency, comprehensive prevention and control of diseases and pests and promoted standardized management for winter intercropping in mulberry field. We also studied and established the advantage areas based on the market targets including saline processed vegetables, quickfreezing vegetables, supermarket fruits and vegetables, and those used as forage grass and for enriching the content of green manure of livestock and poultry. Through the above work, we promoted the sustainable development of leading industries including Nantong silkworm breeding, vegetables, etc. The results could guide the synthetical development and utilization of mulberry field in Jiangsu Province and the middle and lower reaches of the Yangtze River.
