近几年来,在市有关部门的精心规划和推动下,市郊菜田由近郊向中远郊转移,新菜区已形成一定的生产规模.通过老菜区老农的技术辅导,新菜区的蔬菜生产水平与老菜区已基本接轨.但在病虫防治技术上,新菜区还缺乏专业化防治队伍,一旦病虫大发生,势必会影响蔬菜生产.现就在新菜区建立专业化病虫防治体系谈几点看法:一、新菜区病虫专业化阶治体系建设,受阻于使用机种上的老观念新菜区大多数是由粮区转换而来,粮区种植水稻,机动喷雾机习惯上都使用大水量喷雾的工农36型.认为只有喷得水淋淋的,防治病虫才有效.根据菜区历年机动植保机械供应量分析,最明显的要数青浦,近10年来背负式机动植保机械的推广使用一直受阻,使用总量不到150台,不及闵行、嘉定、宝山、浦东新区一年的新增数.推广大水量喷雾的机种,由于受工效及使用时人员配备的限制,专业化防治形不成气候.另外,由于工农36型大水量喷雾机对菜田农药污染严重,蔬菜上的农药残留量高,为确保市民吃菜卫生,被列为不适宜推广使用的机种.
In recent years, under the careful planning and promotion of the relevant departments of the city, the suburban vegetable fields have been transferred from the suburbs to the mid-western suburbs, and the new vegetable zones have formed a certain scale of production. Through the technical guidance of the veterans in the old vegetable zones and the vegetable production in the new vegetable zones Level and the old vegetable area has basically basic.But in the pest control technology, the new vegetable area is also a lack of specialized prevention and treatment team, once the occurrence of pests and diseases, is bound to affect the vegetable production.Now in the new vegetable area to establish specialized pests and diseases Prevention and control system On a few points: First, the new vegetable area pest professional hierarchy system, blocked by the use of models on the concept of the new vegetable area is mostly converted from the food area, grain planting rice, motor spray The machine is customarily used large amounts of water spray workers and peasants 36 type .It is only sprayed with water shower, pest control is effective.According to the vegetable area over the years plant and animal protection machinery supply analysis, the most obvious to the number of Qingpu, the past 10 years, piggyback The popularization and use of motor and plant protection machinery has been blocked, the total use of less than 150 units, less than the new number of one year in Minhang, Jiading, Baoshan, Pudong New Area to promote large water spray models, due to ergonomics and use of staffing Limit, professional In addition, as workers and peasants 36 large-capacity sprayers on the vegetable field pesticide pollution is serious, high pesticide residues on vegetables, to ensure that people eat vegetables health, was classified as inappropriate to promote the use of models.
