近年来,随着西瓜生产技术的不断发展尤其是保护地栽培技术的快速发展,西瓜先进的灌溉方式已成为瓜农高产高效的迫切需要,传统的栽培方式已不能满足生产需求,势必要求西瓜灌溉技术的升级换代[1]。保护地生产水平的提高,引进了滴灌、渗灌、微喷灌等先进灌水技术;这些技术得到了较快的推广与普及,收到了较好效果。北京是严重缺水的城市,为提高水肥利用率,在西甜瓜生产中应用了滴灌、微喷灌、膜下灌溉及水肥一体化技术。提倡少用地下水、巧用天上水、安全使用再生水、合理使用土壤水的理念,坚持“以水定城、以水定地、以水定人、以水定产”的原则,为北京地区节水做出了贡献。
In recent years, with the continuous development of watermelon production technology, especially the rapid development of cultivation techniques in protected areas, advanced watermelon irrigation has become an urgent need for high yield and efficiency of melon farmers. Traditional cultivation methods can no longer meet the demand for production and watermelon irrigation technology The upgrading of [1]. Protected areas to improve production levels, the introduction of drip irrigation, seepage irrigation, micro-irrigation and other advanced irrigation technology; these technologies have been faster to promote and universal, received good results. Beijing is a city with severe water shortage. In order to improve the utilization rate of water and fertilizer, drip irrigation, micro-irrigation, submerged irrigation and integrated water and fertilizer technologies have been applied in the production of melon. Advocate less groundwater, clever use of heavenly water, the safe use of recycled water, the rational use of soil water concept, adhere to the “water city, water to water, water to people, water production” principle, for Beijing Regional water conservation has made its contribution.
