不同栽培条件对油桃生理特性的影响

Effect of Different Cultivation Conditions of Physiological Characteristics of Nectarine

通过温室、露地田间试验,观察并测定了油桃在盛花后新枝萌发累积长度、不同生育期新枝萌发的速度、枝条生长发育的特性等生理指标。结果表明:不同条件下油桃生理特性有很大差异,设施栽培油桃新梢年累积长度和每个生长季节的新梢长度都要高于在露地条件下的新梢长度;设施栽培的油桃新梢在整个生育期有1个明显的生育高峰,而露地栽培的油桃在整个生育期有2～3个生育高峰;油桃的顶端优势比其它果树要表现得更为明显,光照是影响花芽、叶芽分化最主要的环境因子。

Through the greenhouse,open country field experiment,the nectarine in flowers accumulated lengths,different growth stages of the development of new growth speed,the characteristics of physiological indexes of branches were observed and measured.The results showed that the different conditions nectarine physiological characteristics had very big difference,in the greenhouse culture nectarine new shoots accumulate length of years and each of the growing season in new shoots length were higher than in the open country.New branches had 1 birth peak in the whole growth period in the greenhouse,but they had 2~3 birth peaks in open country.The nectarine apical dominance were superior to than others fruit trees.Light was the main effect of flower buds,buds of the differentiation environmental factors.
