| Abstract: | Plant growth, water and heat balance in cotton field are investigated and analyzed. Research results indicated that higher transpiration rate and lower stomatal impedance are beneficial to water absorption and CO 2 metabolization. Plant temperature should be lower than ambient air temperature in order to avoid heat injury. Higher transpiration rate, lower stomatal impedance and the balance between water and heat are basal conditions for high yield in cotton. Frequent and insufficient irrigation are effective to improve the balance of water and heat in sandy soil. |
