基肥配施土壤改良物对西藏盐碱地黑青稞光合特性的影响
Effects of Base Fertilizer Combined with Soil Amendments on Photosynthetic Characteristics of Black Qingke in Saline-Alkali Land of Xizang
摘要
Abstract
In order to explore the effect of base fertilizer combined with soil amendment on photosynthetic performance of black Qingke under saline-alkali environment,and provide theoretical basis for high-yield cultivation of black Qingke in Xizang.In this study,the chlorophyll content and photosynthetic characteristics of flag leaves after anthesis of black Qingke were studied under the treatment of base fertilizer combined with different soil amendments(biochar,humic acid,citric acid).The results showed that compared with conventional fertilization(CK),the chlorophyll content,net photosynthetic rate,intercellular CO2 concentration,stomatal conductance and transpiration rate of flag leaves after anthesis of black Qingke could be improved to varying degrees under the treatment of base fertilizer combined with different soil amendments,and the effective photosynthesis period was prolonged and the leaf senescence was delayed.Among them,the treatment effect of base fertilizer combined with biochar was the best,which provided theoretical guidance for planting black Qingke in saline-alkali land to improve photosynthetic characteristics.关键词
