不同覆盖措施对旱区春小麦产量及碳效率的影响
Effects of Different Mulching Measures on the Yield and Carbon Efficiency of Spring Wheat in Arid Area
摘要
Abstract
In order to achieve both environmental benefits and economic benefits of spring wheat planting in arid areas,based on field experiments,effects of different mulching measures,such as straw strip mulching,plastic film mulching,crushed straw mulching and open field flat planting,on the yield and carbon efficiency of spring wheat in arid areas were studied,and the economic beneficts were evaluated.Results showed that compared with open field flat planting,plastic film mulching significantly increased the dry matter accumulation of spring wheat during the whole growth period with an increase of 37.58%.Straw strip mulching increased the dry matter accumulation at wheat flowering and harvesting stages by 32.65%and 9.83%,respectively.The 1000-grain weight of crushed straw mulching and plastic film mulching were increased by 15.55%and 21.91%,respectively,compared with open field flat planting.Plastic film mulching had the largest increase in total carbon input,which was 1 223.07 kg C/ha higher than that of open field flat planting.Compared with open field flat planting,crushed straw mulching increased grain carbon and plant carbon yield by 38.41%and 23.34%,respectively.Straw strip mulching improved carbon production efficiency,carbon economic efficiency and carbon ecological efficiency by 0.58%,0.45%and 0.24%,respectively.In addition,the economic benefit of crushed straw mulching was 3 882.69 Yuan,which was 22.7%higher than that of open field flat planting.Therefore,each mulching measure could improve the yield and economic benefits of spring wheat,and the straw strip mulching could significantly increase the carbon production efficiency,carbon economic efficiency and carbon ecological efficiency.关键词
