大棚草莓促成高效栽培技术

大棚草莓促成高效栽培是目前草莓生产上一项主要栽培模式，通过大棚建造、良种壮苗、适时定植等栽培技术达到促成高效的目的，最终实现大棚草莓高产、高效。     

秸秆生物反应堆不同剂量发酵剂对日光温室环境及草莓生长的影响

日光温室低温期应用秸秆生物反应堆技术可提高温度，改善作物生长的环境条件，秸秆发酵剂直接影响反应堆的增温效果。设置4种不同剂量的秸秆发酵剂进行研究，对比不同处理土壤20 cm的温度、草莓的各项生物学性状、草莓的产量和效益。通过对比分析发现：应用秸秆生物反应堆后效果较对照优势明显。其中B处理667 m²用玉米秸秆4 000 kg，用10 kg秸秆发酵菌，20 cm土壤温度最大增幅达3.1 ℃，小于C、D，但增温的持久性优于C、D，增温有效期达5个月。草莓的各生物学性状均较对照提高，B处理平均株高、花茎数、叶片数、花朵数、茎粗、结果数比对照分别增加2.2 cm、0.8支、1.8片、2.3朵、0.5 cm、1.3个，较对照每667 m²增产299 kg，增产达14.1%，净增产值达7 000元，增产、增值效果十分显著。     

草莓斑驳病毒的分子杂交检测

为探索分子杂交技术在草莓斑驳病毒(Strawberry mottle virus,SMoV)检测中的运用,利用CTAB法从草莓叶片中提取总核酸,并以此为模板,利用特异引物扩增SMoV非编码区序列,经克隆、测序获得SMoV非编码区序列。系统进化分析结果显示:本研究中的分离物与GenBank中已报道的分离物的亲缘关系较远,独立形成1个小的进化支。以带有病毒特异片段的质粒为模板,运用PCR技术制备了地高辛标记的cDNA探针。以草莓感染SMoV叶片为试材,利用地高辛标记探针可有效检测草莓叶片中的SMoV,草莓总核酸样品稀释10倍后仍可有效检测。     

Increasing strawberry shelf-life with carvacrol and methyl cinnamate antimicrobial vapors released from edible films

The effect of carvacrol and methyl cinnamate vapors incorporated into strawberry puree edible films on the postharvest quality of strawberry fruit (Fragaria × ananassa) was investigated. Fresh strawberries were packed in clamshells and kept at 10 °C for 10 days with 90% RH. Strawberry puree edible films, applied in the clamshell, served as carriers for the controlled release of natural antimicrobial compounds without direct contact with the fruit. Changes in weight loss, visible decay, firmness, surface color, total soluble solids content, total soluble phenolics content and antioxidant capacity of strawberries during storage were evaluated. A significant delay and reduction in the severity of visible decay was observed in fruit exposed to antimicrobial vapors. Carvacrol and methyl cinnamate vapors released from the films helped to maintain firmness and brightness of strawberries as compare to the untreated strawberries. The natural antimicrobial vapors also increased the total soluble phenolics content and antioxidant activity of fruit at the end of the storage period.     

不同浓度萘乙酸对草莓穴盘扦插育苗的影响

in order to study the effects of different concentrations of NAA on Strawberry plug cutting seedling, 100, 200, 300, 400, 500mg / L-15 concentration gradients were set to dip the cuttings. The results showed that 200 mg / L-1 NAA was beneficial to improve the cutting survival rate of strawberry seedlings, promote the growth of roots, stems and leaves, and achieved ideal results.
