仁用杏开花座果的研究进展

仁用杏具有很强的经济、生态、社会效益，非常适合干旱半干旱地区恢复生态系统和发展农村经济。但仁用杏往往座果率低，产量不稳，影响仁用杏产业的发展。综合叙述了对仁用杏开花、座果规律的研究；从内因和外因方面揭示落花落果原因，特别是春季冻害对仁用杏落花的影响；并提出保花保果措施和方法．如水分和养分管理、树体管理、化学技术措施等。重点希望可以解决仁用杏的低温冻害等问题，为生产中提高仁用杏的座果率提供理论依据。

Research Progress on the Flowering and Fruit Set of Kernel-used Apricot

Kernel-used apricot is helpful for the restoration of ecosystems and the development of rural economy in the Arid and Semiarid Areas because of its social benefit, environment and social benefit. But the development of Kernel-used apricot has enormously affected by the low and unstable yield. This article described the flowering, fruit set habit and disclosed the causes of flower and fruit dropping, especially the flower dropping caused by the spring cold injury. And in this article, we hope to find some techniques and methods to defend flower and fruit against spring low temperature and improve the fruit rate from the research of nutrient and water regimes, management of fruit trees, and chemical technology, etc.
