树莓温室栽培技术

对树莓温室生产的几个重要因子，如品种、温湿度、肥水管理、疏枝和修剪、病虫害防治等进行了探讨。经过树莓栽培品种的比较筛选后．2000年9月3日将正常产果的红莓2年生优壮植株移入温室，研究其温室栽培特性。经过一定寒冷期后，于当年12月20日开始扣棚、扣棚105d开花，127d果实开始成熟．比露地栽堵结果期提前40d。扣棚前和采收后进行合理修剪，实施有效的花果管理,严格调控温湿度．及时防治病虫害，生产的果实品质优良。2001年春季平均产果达300kg／666．7m^2，第2年即2002年春季达500kg／666．7m^2。

Raspberry Cultivation Technique in Greenhouse

Such factors as the cultivars, humidity, temperature, light, fertilizer and water management, pruning, and disease and pest control for raspberry production in greenhouses were studied. Two-year-old plantlets were transplanted into the greenhouses on September 3of 2000 and normal management was adopted. The plastic film was covered on December 20 after enough chilling time. The raspberry began to bloom 105 days after the coverage and produced ripe fruits 127 days after the coverage. The fruiting phase was 40 days earlier as compared with the openland production. Quality fresh fruits were obtained through proper management, including pruning prior to shed coverage with the plastic film and post to harvest, flower and fruit thinning, humidity and temperature regulation, and disease and pest control. A good yield of 4.5 tons per ha in the spring of 2001 and 7.5 tons per ha in the spring of 2002 was harvested.
