国际切花市场竞争十分激烈,国内切花事业正在崛起。发展切花生产普遍引起关注。为了提高切花市场竞争能力,必须抓住鲜、快、配套和常年供应四个环节。有关国家的一些做法,值得借鉴。保鲜由过去单纯地依靠低温保鲜,发展成在低温和低压条件下保鲜,提高了保鲜效果。经试验:玫瑰、菊花、香石竹切花,在一般冷贮条件下,能保鲜7—12天;而同样的低温,在40—80mmHg低压条件下,可保鲜28—56天。百种花卉插枝,在0—4℃、40—150mmHg条件下,能保存40天左右,把气压降低到40—80mmHg,则可延长至80天左右。如天竺葵
International cut flower market competition is fierce, the domestic cut flower business is rising. The development of cut flower production has aroused general concern. In order to improve the competitiveness of cut flowers market, we must seize fresh, fast, supporting and perennial supply of four areas. Some of the country’s practices are worth learning from. Preservation in the past relying solely on low-temperature preservation, developed into low temperature and low pressure preservation, improve the preservation effect. The test: roses, chrysanthemums, carnation cut flowers, under normal cold storage conditions, fresh 7-12 days; the same low temperature, 40-80mmHg under low pressure conditions, fresh 28-56 days. Hundreds of flowers cuttings, at 0-4 ℃, 40-150mmHg conditions, can be stored for about 40 days, the pressure is reduced to 40-80mmHg, can be extended to 80 days. Such as geranium
