河北省环渤海旱碱区玉米秸秆条带还田-冬小麦条带种植技术的田间效应
Field Effects of Maize Straw Strip-returning and Winter Wheat Strip-planting Technology in Arid and Alkaline Areas around the Bohai Sea in Hebei Province
摘要
Abstract
In order to explore effective technological models for increasing wheat yield and rational resource utiliza-tion in arid and alkaline areas around the Bohai Sea in Hebei Province,the field effects of maize straw strip return-ing and winter wheat strip planting technology on winter wheat growth and yield,as well as changes in soil moisture during wheat growth,were studied with conventional planting technique as the control(CK).The results showed that the plant height of wheat planted with strips was significantly higher than that of CK,and the ear length and grain number increased by 0-9.6％and 5.4-21.3％,respectively.The aboveground biomass and yield increased by 0.1％-18.4％and 9.6％-25.0％,respectively.The net photosynthetic rate during the booting stage can increase by up to 27.0％.The moisture content of the 0-40 cm soil layer increased by 2.1％-29.0％,and the water use efficiency improved.The technology of maize straw strip-returning and winter wheat strip planting can not only enhance the grain production capacity in arid and saline alkali areas,but also achieve the goal of rational utilization of straw re-sources,providing technical support for the utilization of saline alkali barrier farmland.关键词
