<正>近年来,草莓种植迅速发展,但随之也出现不少问题。重茬和连作频繁造成草莓的某些病害大发生、土传病害加重、营养失衡、生理失调。苗期定植后发育迟缓或幼苗徒长,是造成草莓产量降低的重要因素。冬季低温等极端天气造成花托受冻,滥用激素造成畸形果,使草莓的产量和品质大受影响。针对目前生产中普遍存在的问题,给农民们推荐一种简单高效的温室草莓丰产栽培技术。1选苗与定植选择优质草莓苗是定植成活的关键。应根据不同区域选择当地适宜品种定植。定植时,常因高温 相似文献

草莓品种宁玉大棚促成栽培定植试验 总被引：4，自引：0，他引：4
《中国果树》2014,(1)
以草莓品种宁玉为试材,研究在大棚内促成栽培时,不同定植时间和种苗质量下的植株生长情况、物候期、果实品质和产量的差异,以确定宁玉在大棚内促成栽培适宜的定植时间和种苗质量。结果表明,宁玉草莓进行大棚促成栽培宜早定植,在8月底定植植株生长势强,前期产量和总产量较高;定植种苗选择根颈粗0.7 cm左右的中等苗较好。 相似文献

受气候条件的影响,草莓在高海拔冷凉地带的栽培,采收期短,产量低。试验表明,设施栽培可以延长花芽分化及发育时间,使果实的采收期延长,还能抑制匍匐茎的发生,从而提高草莓产量。温室反季节栽培是该类地区草莓生产比较合理的方式。 相似文献

Plants of six strawberry cultivars were raised under controlled conditions and tested for flowering and yield potential. Short days (SD) at intermediate temperatures for 4 weeks in August induced profuse flowering in subsequent long days (LD) in all cultivars except the late-flowering ‘Malwina’. LD conditions induced flowering only in ‘Nobel’, which has an everbearing parent. ‘Nobel’ and ‘Saga’ exhibited broad temperature adaptation for SD floral induction, which was generally reduced or suppressed at 9 and 27°C. After autumn planting, all cultivars flowered most abundantly in plants raised in SD and intermediate temperatures. Flowering was earliest in ‘Nobel’ and ‘Rumba’. Plants that did not reach floral commitment after 4 weeks in SD continued and completed induction under subsequent natural SD conditions after planting in the field, demonstrating the capability of fractional induction. Berry yield varied in parallel with flowering in the field and was always higher in plants raised under SD conditions. The traditional cultivars ‘Florence’ and ‘Sonata’ out-yielded the more recent cultivars. Some cultivars lost more than two thirds of their initiated flowers during the winter with obvious consequences for their yields. With proper raising management, acceptable yields were obtained after autumn planting even in a cool Nordic climate. 相似文献

为有效缓解广州地区冬春季节瓜果蔬菜的供给不足,保障蔬菜质量安全,提高种植经济效益,满足居民对优质安全、绿色无公害蔬菜的需求,大面积推广有棱丝瓜标准化高效丰产栽培技术具有重大意义。在充分利用有棱丝瓜这一地方品种耐湿、抗寒特性的基础上,于秋冬季塑料大棚内,采用薄膜覆盖简易生产技术,促使有棱丝瓜延后成熟、连续结瓜,并且结合陆续采收的方式,延长市场供应时间;同时采取品种选择、温汤浸种、低温炼苗、高畦整地、双株定植、田间管理、采收留种等措施,对解决春节期间丝瓜的市场需求和打破常规生产中出现的连作障碍具有明显改善作用。 相似文献

温室黄瓜不同栽培制度对土壤微生物群落功能结构的影响 总被引：3，自引：0，他引：3
以连作8年黄瓜的温室土壤为研究对象,设计了4种栽培制度,除CS3早春茬种植番茄外,其它处理传统两茬均为黄瓜,以传统两季种植。夏季休闲处理为对照,进行3年的盆栽试验,采用第3年夏茬后数据评价不同栽培制度对土壤微生物功能结构多样性,碳源利用,微生物量碳、氮和秋冬茬黄瓜产量的影响。结果表明,连作黄瓜土壤夏季填闲大蒜（CS4）、茼蒿（CS2）、菠菜—白菜（CS3）后微生物群落功能多样性、均匀度和Biolog ECO板每孔平均颜色变化率（AWCD）相对于对照均显著增加,其72 h AWCD值分别增加了57.0％、26.1％、57.2％,在主成份1和主成份1至3加权上,对照与其他处理存在显著差异;CS2、CS3、CS4在多聚物和碳水化合物的利用上显著高于对照,且CS2对芳香类化合物的利用显著高于其他处理;CS2、CS3、CS4微生物量C/N分别为14.4、14.9、9.3,显著高于对照;且CS2与CS4显著增加了秋冬茬黄瓜的产量。综合结果表明：CS2、CS3、CS4均能显著改变土壤微生物碳源,从而改变微生物群落的组成及其对土壤碳源的利用。 相似文献

Studies were made to determine some of the factors which could modify the influence of a cold treatment of transplants on the maturity characteristics of three autumn cauliflower varieties. These included controllable experimental variables and uncontrollable environmental factors some of which were investigated by multiple regression techniques.Results from the four experiments indicated that while the cold treatment considerably shortened the harvest period of the majority of the crops grown, the magnitude of the response of individual crops was affected by the temperature conditions under which the plants were raised and also, on some occasions, by temperature conditions prevailing just after planting and at harvest. There were varietal differences in responsiveness to the cold treatments. Selection for uniformity of transplant growth stage did not increase the cold treatment effect. It is suggested that plant-to-plant variation in low temperature requirement for curd induction may be a factor contributing to the result. The possible use of cold treatment of transplants in commercial practice is discussed. 相似文献

After cold storage for various periods (42, 99, 155, 189, 227 and 259 days) strawberry waiting-bed plants cultivar ‘Elsanta’ were planted on six dates between January and August. Plant performance was evaluated simultaneously in a growth chamber under controlled environmental conditions and in a greenhouse. Starch content in the crown tissue was clearly reduced during the cold storage period.
In the greenhouse trials a variable decline in fruit number and yield per plant was found in relation to the length of cold storage and the temperature conditions during the growth and harvest period. Also in the growth chamber, under a constant temperature regime, a significant decline in the number of flowers per plant developing up to anthesis was observed after increasing periods of storage. This indicates that it is not only stressing climatical conditions after planting which are influencing the performance of cold stored plants. Also, the length of cold storage strongly affects plant vigour and productivity. This is related to the carbohydrate status of the plants after cold storage. 相似文献
