杏为我国重要果树之一,分布广泛,北方地区尤多,但栽培管理较为粗放,且存在冻花芽、败育花等问题。这些问题的解决与栽培技术的提高及花芽分化密切相关,迄今对杏花芽分化规律的研究较少。1981～1982年我们以兰州地区大接杏为试材,开展了杏花芽分化的研究工作。 Apricot is one of the important fruit trees in our country. It is widely distributed in northern China, but cultivation and management are more extensive. There are some problems such as frozen flower buds and abortion flowers. The solution of these problems is closely related to the improvement of cultivation techniques and flower bud differentiation. So far, there has been little research on the law of flower bud differentiation. From 1981 to 1982, we took Daxian apricot in Lanzhou as test material and carried out the research on almond flower bud differentiation.
