水肥耦合对燕麦光合特性和产量的影响
Influence of Photosynthetic Characteristics and Yield in Oats on Coupling of Fertilizer and Irrigation
摘要
Abstract
In order to identify the relationship of Fertilizer and Irrigation on oat production in dry area, adopt the split-plot design, Study of different treatment combinations of water and phosphorus to photosynthetic characteristics of oats and water use efficiency and the impact of changes in field. The results showed that;water chlorophyll content among treatments significant differences in the jointing stage, the rest period is not obvious, the time difference between the gradient of fertilizer significantly. Plant WUE significantly with the moisture gradient,the gradient did not change significantly with the fertilizer, the net photosynthetic rate increased with the increase of moisture gradient. Transpiration rate increased with the increase of moisture gradient increased, W2P2 handle the largest WUE,W2P1, the second. Feng Yu season phosphorus fertilizer on growth of oat plants on the role of photosynthetic efficiency significantly. WUE benefits to water two most prominent low-level WUE than high P treatment. Significant difference between different treatments, biomass W1P3, W2P4 , W3P4 deal with the highest yield, W3P4 W2P4 The yield increased 5% more than W1P4 by 29%. Grain yield W1P2, W2P2, W3P2 handling the highest yield, W3P2 W2P2 The yield increased 6% more than W1P2 51. 8% increase. Biological and grain yield at the maximum of three water treatments, P fertilizer 90 kg/ha and 30 kg/ha department appears.关键词
