甲壳素对克服日光温室草莓连作障碍的效果研究
|
摘要
针对日光温室草莓连作易发生植株根系弱化、病虫害加重、果实品质下降等连作障碍问题,开展了在日光温室连作草莓管理中施用甲壳素(阿波罗963养根素)灌根的应用效果试验。结果表明,草莓定植到开花期连续使用甲壳素灌根3次,对提高草莓植株株高、座果率、早熟性、平均单果重、产量品质及延缓根系衰老方面效果明显,与对照相比,植株高度提高5.6%、座果数量提高20%、前期结果数量提高12.8%、平均单果重增长3.61%、每667 m~2产量增加30.19%、可溶性固形物含量增加0.5%、根系延展长度提高17.8%,根系鲜重提高26.9%,这为缓解草莓连作障碍和指导日光温室连作草莓施用甲壳素提供了理论依据。
In order to solve the problems of strawberry continuous cropping in solar greenhouse, such as root weakening, pest and disease aggravation, and fruit quality degradation, this paper studied the application of chitin(Apollo 963 nutrient) in strawberry continuous cropping management in solar greenhouse. The results showed that the continuous use of chitin for three times from strawberry planting to flowering stage significantly increased the plant height, flowering fruit setting rate, early maturity, average fruit weight, yield quality and delayed root senescence of strawberry plants. Plant height increased by 5.6%, fruit number increased by 20%,early result increased by 12.8%, average single fruit weight increased by 3.61%, yield increased by 30.19%per 667 m2, soluble solid content was increased by 0.5%, and root extension length increased by 17.8%, the root fresh weight increased by 26.9%, which provided a theoretical basis for alleviating strawberry strawberry continuous cropping obstacles and guiding the application of chitin in strawberry greenhouse.
