Abstract:

To explore the influencing factors of chlorophyll content of sweet cherry leaves in solar greenhouse, the content of chlorophyll a, chlorophyll b and total chlorophyll in sweet cherry leaves under different greenhouse locations, different tree directions, different tree shapes and varieties, different leaf fertilizer treatments were measured. The results showed that the chlorophyll content of sweet cherry leaves in the east of the greenhouse was significantly lower than that in the west and central part, and the chlorophyll content in the south and east direction of the tree were significantly higher than that in the west and north direction. The contents of chlorophyll a, chlorophyll b and total chlorophyll were different among sweet cherry varieties. The chlorophyll content of sweet cherry leaves was increased by spraying leaf fertilizer. There was no significant difference in chlorophyll content in sweet cherry leaves between three tree shapes in the test.

Key words: greenhouse culture, sweet cherry, chlorophyll content, solar greenhouse
