破眠剂对设施甜樱桃的影响

Effects of Dormancy Breaking Chemical on Sweet Cherry under Protected Cultivation

为了探索破眠剂对设施甜樱桃的影响,以山西省设施甜樱桃主栽品种美早、红灯、红玛瑙、龙冠、早大果为试验材料,研究了喷施不同浓度破眠剂对设施甜樱桃物候期、坐果率和果实品质的影响。结果表明,喷施破眠剂可一定程度提早设施甜樱桃萌芽期、始花期、成熟期,破眠剂浓度对大棚甜樱桃物候期的影响差异不明显;破眠剂对甜樱桃坐果率有一定程度降低,对设施甜樱桃的品质无明显影响。

To explore the effects of dormancy breaking chemicals on sweet cherry under protected cultivation,the effects of different concentrations of dormancy breaking chemicals on phenological period,fruit setting rate and fruit quality of sweet cherry under protected cultivation were studied by using the main varieties of sweet cherry in Shanxi province,such as Meizao,Hongdeng,Hongmanao,Longguan and Zaodaguo.The results showed that the germination stage,flowering stage and ripening stage of the sweet cherry were earlier after the application of dormancy breaking chemicals,and the effect of the dormancy breaking chemicals concentration on the phenological period of sweet cherry was not significant.The application of dormancy breaking chemicals could reduce fruit setting rate of sweet cherry of protected cultivation.The application of dormancy breaking chemicals had no obvious effect on the quality of sweet cherry.
