最近几年,江苏省宝应县望直港镇加速高效设施蔬菜种植园区建设。近两年园区已投入基础设施建设资金800多万元,建成水泥道路4800米,衬砌渠道9000米,桥梁3座,大小泵站5座,涵洞5座,架设电力线路2600米,喷滴灌设施1000多亩,沿路绿化配套。桥、涵、闸、洞配套齐全,水、电配送到田头等生产条件的改善,极大的提高了抗自然风险能力。目前大棚建成区2000亩,主要分为六大种植区域,辣椒、草莓、葡萄、油桃、西瓜、时令蔬菜等已形成一品一区,亩均效益5000元以上。随着地区温室蔬菜种植产业不断向前发展,日光温室番茄灰霉病的发生率呈现上升趋势,常常因为防控不到位给种植户造成严重的经济损失。基于此,本文主要结合实际情况,就日光温室番茄灰霉病发病症状、原因、发病规律和绿色防控技术进行了分析,希望通过本次研究对同行有一定帮助。
In recent years, Baoying County, Jiangsu Province, Wang Zhijin Town, accelerate the construction of efficient vegetable garden plantation. The past two years the park has invested more than 800 million yuan of infrastructure construction, built 4,800 meters of cement road, lining channel 9,000 meters, 3 bridges, size pump station 5, culverts 5, erection of power lines 2600 meters, drip irrigation facilities 1000 Mu, greening along the road. Bridges, culverts, gates and tunnels are fully furnished with improved water and electricity distribution to TianTu and other production conditions, greatly improving their ability to resist natural risks. At present, 2,000 mu of greenhouses are built, which are mainly divided into six major planting areas. Pepper, strawberries, grapes, nectarines, watermelons and seasonal vegetables have formed a product area of over 5,000 yuan. With the continuous development of the vegetable growing industry in the region, the incidence of tomato gray mold in the solar greenhouse is on an upward trend, often resulting in serious economic losses to the growers due to inadequate prevention and control. Based on this, the paper mainly analyzed the symptoms, causes, pathogenesis and green prevention and control of tomato gray mold disease in solar greenhouse according to the actual situation. It is hoped that this study will be of some help to our colleagues.
