近十几年来,山东省以冬暖大棚(日光温室)为龙头的保护地设施蔬菜栽培迅猛发展,已成为山东蔬菜产业的重点和特色。但是,由于各种条件的限制,各地棚型结构还不规范,性能差别很大;有些地区的冬暖大棚不具备抵御灾害性天气的能力。在2000年春节前后的低温弱光条件下,受到了不同程度的损失。为了解这次灾害性天气对保护地蔬菜生产造成的影响,我们于2000年3月对德州、淄博、潍坊、烟台、日照、临沂、枣庄、菏泽、泰安、济南等地市的重点蔬菜产区进行了调查。现将调查结果报告如下: 一、受灾的程度 2000年春节前后的低温、寡照、雨雪天气,不同地区、不同蔬菜种类、不同种植户受害程度有很大差别。就总体情况来看,黄瓜、西葫芦绝产约10%,减产20%～30%;番茄绝产约5%,减产20%;茄子、辣椒越冬茬死苗约5%,减产20%～25%,春节前产量很低;早春茬茄子、辣椒苗损失50%以上;甜椒绝产
In the past ten years, the rapid development of vegetable cultivation in Shandong Province with the warm greenhouse (solar greenhouse) as the leading site has become the focus and characteristic of Shandong vegetable industry. However, due to various conditions, the shed structure is not standardized and its performance varies greatly. In some areas, winter warm sheds do not have the capability of resisting disastrous weather. In the low temperature and low light conditions before and after the Spring Festival in 2000, suffered different degrees of loss. In order to understand the impact of this devastating weather on vegetable production in protected areas, we conducted a survey on key vegetable producing areas in Dezhou, Zibo, Weifang, Yantai, Rizhao, Linyi, Zaozhuang, Heze, Tai’an and Jinan in March 2000 We conducted a survey. The results of the investigation are reported as follows: I. Degree of Disaster Victims Before and after the Spring Festival in 2000, there were great differences in the degree of victimization among different types of vegetables, low temperature, low light, rain and snow, weather in different regions, and different types of vegetables. In terms of the overall situation, cucumber and zucchini produce about 10% of the total output, 20% to 30% of the total production. The yield of tomato is about 5% and the yield is reduced by 20% , Low yield before the Spring Festival; early spring eggplant, peppers seedlings lost more than 50%; pepper abortion
