不同碳氮施肥组合对新疆滴灌棉田冠层CO_2浓度、光合作用和产量的影响
Effects of Different Carbon and Nitrogen Fertilizer Combination Treatments on Canopy CO_2 Concentration,Photosynthesis and Yield Formation of Cotton Field under Drip Irrigation in Xinjiang
摘要
Abstract
Based on pipe network system of drip irrigation under plastic film,the possibility of increasing cotton field canopy CO2 concentration and its effect were investigated via fertilization of dissolvable carbon fertilizer（water insoluble matter 1%）.By setting different carbon and nitrogen fertilizer combination treatments,canopy CO2 concentration,leaf photosynthetic rate and yield formation of cotton field in Xinjiang were analyzed.The results show that canopy CO2 concentration was increased with the amount of carbon fertilizer increasing in cotton florescence.Under the conditions of providing adequate irrigation water and inadequate N fertilization,the leaf photosynthetic rate was higher under C300＋N113.55 treatment（C300 means that the amount of ammonium bicarbonate was 300 kg/hm2）,and N113.55 means that the amount of nitrogen was 113.55 kg/hm2,and it was the lowest under C600＋N0 treatment.The seed cotton yield under C300＋N113.55 treatment was the highest,and it was the lowest under C600＋N0 treatment.There was a significant difference in seed cotton yield among different carbon and nitrogen fertilizer combination treatments.关键词
