In open field,the environment is a critical determinant of crop yield and produce quality and it affects the geographical distribution of most crop species.In contrast,in protected cultivations enviro
An overview of the good agricultural practices for greenhouse horticulture in the Mediterranean and South East Europe regions is presented and discussed.Special emphasis is given on the effects of cli
Influence of continuous light with different red/blue ratio on photon flux density (R/B ratio) on nitrate and soluble sugar content was studied by growing lettuce (Lactuca sativa L.) under continuous
1 Purpose Cucumber is one of the most important vegetables in the world.Recently,over-utilization of chemical fertilizer has caused secondary salinization in Chinese greenhouse.The excessively accumul
Strategies for improving greenhouse crop production should target both developing advanced technological systems and designing improved plants.Based on greenhouse experiments,crop models and biotechno
Introduction Accompanying the world crisis of energy resources and increase in emission of greenhouse gases,energy-saving,ecological and sustainable greenhouse cultivation is becoming important issue.
Purpose Nitrogen fertilizer plays an important role in crop yield and quality.To satisfy the nitrogen demaud,farmers use very large amounts of nitrogen fertilizers to obtain maximum yields.These high
连作障碍已成为设施栽培蔬菜可持续发展的瓶颈问题,水旱轮作是治理连作障碍的有效、生态模式.本文归纳了在常规设施蔬菜基地利用水生蔬菜开展水旱轮作的主要模式及注意事项,并提出了进一步研究的设想.水生蔬菜作为我国特色蔬菜,与主要旱生蔬菜已基本育成设施专用品种、并实现周年生产供应相比,除了水芹育成适于常规旱生蔬菜设施内土壤湿润条件下种植的湿栽水芹新品系“G0601”和“D07”外,莲藕、茭白等主要水生蔬菜至
以红色LED(660±20nm)和蓝色LED(450±20nm)组合制成的LED灯管作为组培人工光源,研究光照度为35μmol·m-2·s-1时,红蓝光质比(R/B)分别为4、6、8、10的光环境培养条件下甘薯组培苗的生长情况,以相同光照度的荧光灯为对照,培育甘薯组培苗28d.结果表明:660nm红光和450nm蓝光组合可有效抑制植物徒长、降低地上部分含水率和提高根冠比;荧光灯下生长的植株地上鲜重
甜樱桃是当前种植效益最好的果树之一,因果实外观艳丽,营养丰富,深受消费者喜爱,各适宜产区积极规划发展.但甜樱桃花期容易遭受低温冻害,成熟期遇雨易裂果,严重制约了栽培发展.近十年来山东、辽宁等地开展了甜樱桃设施栽培,不仅使果品提早成熟1~2个月,同时还解决了冻害和裂果问题,种植效益高,销售价格高达60~400元/kg,市场空间巨大,各主产区积极推广.但设施栽培投资高、风险大、管理技术尚不成熟,各地均
