水肥交互对红枣产量及生理状况的影响
Interaction Effects of Water and Fertilizer on the Yield and Physiological Condition of Zizyphus Jujube
摘要
Abstract
[Objective] To understand the effects of water stress and nutrient stress on the yield of Zizyphus Jujube in Xinjiang.[Method] Based on an interactive test of two water gradients and two nutrient gradients,soil moisture content,red date yield as well as nutrients and chlorophyll fluorescence of red date leaves from red date sample plots in Akesu City (Xinjiang) under different water and fertilizer conditions were tested.[Result] (1) Soil moisture content increased with the increase of irrigation amount;(2) With the increase of water and nutrients,Zizyphus Jujube yield,N,P and K contents in leaves,maximum photochemical quantum yield of PSⅡ,PSⅡ actual photochemical efficiency (φPSⅡ),photochemical fluorescence quenching coefficient (qP) and photosynthetic electron transport rate increased,while the initial fluorescence (Fo) and non-photochemical quenching coefficient NPQ decreased;(3) High water and nutrient contents contributed to higher Zizyphus Jujube yield and better physiological indexes than other conditions.[Conclusion] The addition of water alone is more beneficial to the growth of red date than the single nutrient,and water is the main factor to affect the yield of jujube.关键词
