杀菌剂按其有效成分来源可分成植物源杀菌剂、微生物源杀菌剂、矿物源杀菌剂和化学合成杀菌剂。目前在蔬菜作物上登记的杀菌剂有效成分约有150 种，登记的剂型有约30 种，以不同有效成分登记的制剂产品逾220 种，大量有效成分及大量产品被重复登记，但一些小作物及部分新生重要病害尚缺乏登记药剂。杀菌剂被广泛应用于蔬菜真菌、卵菌、细菌、病毒、线虫等病害的防治，然而由于过度用药，过分依赖化学防治，轻视生态调控、生物防治、农业防治，杀菌剂残留超标及作物病原菌抗药性频发等现象较为普遍，生产中亟待开展杀菌剂精准高效使用、病虫害的综合防控及农药减施增效技术的应用推广，为蔬菜产业的可持续发展提供技术支撑。

螺丝椒，因其呈大牛角形，果面有褶皱，形似螺丝而得名，实际上指的是一类品种。与一般牛角椒相比，螺丝椒的辣香味更浓，皮更薄肉更脆，早期的代表品种有兰州大羊角、“猪大肠”等地方品种。多年来螺丝椒在甘肃、青海、新疆等西北地区一直有较大规模种植，但由于该类型品种在抗病性、产量等方面不能满足生产的需求，从20 世纪90 年代开始，甘肃省农业科学院蔬菜研究所等一些育种单位，通过将从国外引进的辣椒品种与国内“猪大肠”等地方品种进行组合选配，获得了一批商品性好、产量高、综合农艺性状较好的优良品种，使得西北等地螺丝椒种植面积逐年增加。近年来，随着人口的流动、交通运输的便利，以及蔬菜周年供应的需求，该类品种除了在新疆、甘肃、宁夏、陕西、山西等传统主栽区域栽培外，在我国东部、南部地区也有发展的趋势，如山东、河北、河南中部地区、广东雷州半岛、海南等地。除了传统露地栽培模式，还出现了早春、秋延迟大棚和越冬温室栽培等多茬口和多种栽培模式，并且在反季节南菜北运的蔬菜中也占有了一定的比例。随着栽培面积的扩大和栽培模式的多样化，对品种的要求也越来越“苛刻”。对于种植者来说，除需要品种具有抗病、丰产等特性外，品种的早熟性、连续坐果能力和耐贮运性也是他们所关注和需求的。而对于消费者而言，除需要较浓厚的辣香味外，肉质的脆嫩程度则亦在考虑之中。目前，除西北等当地科研院所在育种方面取得的成果外，因受市场的刺激，山西、陕西、江西、安徽、湖南等地在品种繁育上也各展其长，故，在种子市场上，适合各个地区、各种栽培模式的螺丝椒品种纷纷登场，其中不乏在抗病性、商品率、食用品质、坐果率等方面较以前有较大提高的优良品种。特别值得一提的是，原来螺丝椒在西北地区种植，西北地区昼夜温差大，对品种的抗病性并无特别严格要求。然而，随着广东、海南等地螺丝椒种植面积的发展，对品种的多抗性要求也逐渐显现，尤其在对叶斑病、病毒病的抗性需求上。因此，种植户在大面积引种螺丝椒品种前，一定要了解品种特性和市场需求，并进行小面积试种，以降低种植风险。

入世以来,我国农产品出口贸易得到了快速发展,出口总量以每年15%～20%的幅度增长。但由于国内出口企业间的无序竞争和国外非关税壁垒的存在,农产品出口遭遇越来越大的阻力,其中我国主要出口蔬菜之一的大蒜同样面临这样的困难。据联合国粮农组织(FAO)统计,2003年全世界大蒜种植面积为100.18万hm2、产量为1013.3万t,其中中国为48.92万hm2、660万t,分别占48.8%、65.1%,在世界大蒜贸易总额中占60%～70%的份额。世界大蒜看中国,我国大蒜的动态为世界各产蒜国及进口国所关注。为促进大蒜出口持续、健康、稳定的发展,中国食品土畜进出口商会对我国大蒜出口实行了最低限价标准:日本550美元·t-1(FOB)、美国700美元·t-1(FOB)。实施这个限价标准以来,我国大蒜出口贸易是否像曾经预计的那样,进一步规范了大蒜市场竞争秩序,并确保了整个行业的长期健康发展呢?同时,我国大蒜出口环境是否得到了较大改观,使更多从事大蒜产销的企业看到了曙光呢?目前我国大蒜出口的现状到底如何,在困境面前又如何面对?特此,本刊约请全国大蒜委员会秘书长、江苏省大蒜协会会长丁超先生撰写此文,希望给观望或者正处于困惑中的读...
