In order to improve the yield of cucumber and ensure food safety by investigating response nutrient stress, especially compound gas-exchange growth parameters, biomass, root development were measured compared. The results showed that compared with control (CK), different treatments had effects on these under short-term nitrogen (N) or potassium (K+) lateral roots hair was promoted. research stress provided a basis for establishing reasonable irrigation strategies as well improvement fertilizer utilization rate yield, which great significance maintaining national security. addition, this beneficial reveal mechanism crops NK conduct in-depth phenotypic information characteristics stress. It theoretical subsequent construction comprehensive evaluation system greenhouse health status.
