根施甘氨酸对日光温室秋冬茬黄瓜生长、产量及品质的影响

Effect of Root Application of Glycine on Growth,Yield and Quality of Cucumber Grown in Solar Greenhouse in Autumn and Winter

以油亮型密刺黄瓜21-19为试材,设置根施清水及3‰、5‰、7‰甘氨酸共4个处理,研究甘氨酸对日光温室秋冬茬黄瓜生长、产量及品质的影响。结果发现,根施甘氨酸处理提高了叶片净光合速率、叶绿素含量和抗氧化酶活性,降低了丙二醛含量,增加了果实产量,提高了果实中可溶性糖和VC含量,表明根施甘氨酸可以通过提高黄瓜植株叶片的光合速率和抗氧化能力促进增产,同时改善品质。鉴于经济性考虑,以每株根施3‰浓度的甘氨酸效果最佳。

Taking dense spines and glossy type cucumber‘21-19’as test material,this experiment set root application of glycine with different concentrations(0,3‰,5‰ and 7‰)4 treatments to study the effects of glycine on growth,yield,and quality of cucumber in autumn and winter in solar greenhouse.Results showed that root application of glycine treatment could improve net photosynthetic rate,chlorophyll content and antioxidant enzyme activity of leaves,reduce malondialdehyde content,increase fruit yield,and raise soluble sugar and VC contents in fruit,indicating that root application of glycine could increase yield and improve quality of cucumber by improving photosynthetic rate and antioxidant capacity of leaves.In view of economic consideration,root application of 3‰ concentration glycine had the best effect.
