Abstract：Agricultural supply-side structural reform is aimed at activating the internal power of the rural development of agriculture， and is more focused on quality， benefit and sustainable development. It is of great theoretical and practical significance to develop Gobi agricultural in Gansu province， which are demanding for services to develop modern agriculture， solving the need of grain and vegetables to compete for land and expand agricultural development space， solving the recycling utilization of agricultural waste and improving the agricultural ecological environment. The paper put forward the suggestions as followers aiming at existing problems in Gobi agricultural development： protruding the planning lead and optimizing the spatial layout;scientific and reasonable development of Gobi agriculture based on volume of water;strengthening support for scientific and technological innovation and foster new energy for Gobi agricultural development;giving full play to the advantages of location and brand， and promote coordinated development of the Belt and Road;strengthening the training of talents and promoting the development of Gobi Agriculture.

大花月季（Sect.chinenses）是薔薇科蔷薇属观花灌木，又名香水月季、观赏月季、壮花月季，是现代月季的主体部分。其品种繁多，植株健壮，花朵硕大丰满，花姿雅致、花型优美、花香浓郁、鲜艳明快，具有三季有花、连续开放且花期长的特点。花单朵或群聚，观赏价值极高，具有其他月季及观赏植物不可替代的独特作用[1 - 2 ]。兰州地区虽种植了大量的月季，但品种单一，造景单调，仍以花朵较小、植株低矮的丰花月季为主，且因栽培不当出现生长不良或大面积死亡现象。因此，引种栽植抗逆性强的现代大花月季品种，不仅是改善兰州地区夏秋季开花植物单一、物种多样性不足的一个重要环节，而且对全面提升绿地景观效果具有重要的意义。近年来，兰州植物园从国内外引进29个新优大花月季品种，根据对其生物学特性、生长势、抗逆性等方面进行观察记录和试验比较，筛选出适宜兰州地区栽植的23个优良品种，现介绍如下，供园林工作者做参考。
