集约化育苗助力北京蔬菜春耕

内容摘要:  近日,记者从在大兴区举行的北京市第四届集约化育苗竞赛上了解到,今年全市蔬菜春耕主推集约化育苗技术,仅春温室、大棚茬口
   近日,记者从在大兴区举行的北京市第四届集约化育苗竞赛上了解到,今年全市蔬菜春耕主推集约化育苗技术,仅春温室、大棚茬口集约化育苗量就达1.57亿株,与传统育苗方式相比,省水约15.7万吨。

农民信息网新玩家汇娱乐 www.fxnonstop.com   在现场共有来自京郊65家育苗场和育苗大户的161份秧苗样品参赛,比赛分自根组、嫁接组2个组别,每组又分番茄、黄瓜、茄子、辣(甜)椒4个小组,还设置了其他品种展示组。通过专家现场评比、田间记录情况和育苗技术总结综合考量,各单元分别评出育苗能手一、二、三等奖共36名。

  北京市农民信息网新玩家汇娱乐技术推广站副站长李红岺说,蔬菜集约化育苗规模迅速扩大,建成市级蔬菜集约化育苗场55个,标准园育苗点21个,拥有百亩规模以上蔬菜园区自用育苗点和育苗大户80余家,涌现出一批年产商品秧苗500万株以上的育苗场,以及生产单一品种的专业育苗场。全市去年蔬菜集约化育苗1.8亿株。

  推广站育苗室主任赵景文说,蔬菜集约化育苗省工省时省水。和传统育苗方式不同,集约化育苗技术以穴盘为主要容器,基质为草炭、蛭石、珍珠岩。以72穴苗盘为例,整个育苗期共浇水12次,一次用水1.2公斤左右,单株秧苗耗水量满打满算0.2公斤;而传统育苗粗略统计,同样育1株苗耗水量至少1.2公斤,比集约化育苗多耗水1公斤。

新玩家汇娱乐  近年来,推广站针对提高育苗成苗率、壮苗率等技术节点,开展育苗基质筛选、黄瓜控徒长、甜椒嫁接等技术试验12项,完善集成了番茄、黄瓜、甜椒、茄子、芹菜、生菜等6种蔬菜集约化育苗的标准化生产技术。示范推广多个优良蔬菜品种,主推技术8项,包括品种优化、穴盘孔穴选择、精量播种、专用基质、专用肥料、蔬菜套管嫁接、种苗化控、病虫害综合防治等。

新玩家汇娱乐  同时,依托北京农技推广网建立北京市蔬菜集约化育苗技术交流平台,汇集育苗资源,实现技术交流、信息共享、种苗调剂;通过对信息的筛选分析,总结育苗相关技术,及时发布技术指导措施。目前,通过区县推荐、育苗场信息上报和严格遴选,平台成员发展到24家、育苗量6000万株;收集、发布行业动态、育苗技术、供求信息等320余条;年调剂秧苗100多万株。
