麦田套种大豆,是我灌区干旱少雨、无霜期短、经济利用有利的自然资源—光、水、热夺取高产的重要途径。但能否获得理想的经济效益,关键在于选择好搭配品种和确定合理的套种比例。为此,在三年的试验中,对麦豆的主要生育时期进行了干物重、叶面积指数、净光合生产率及叶绿素含量等一系列生理指标的测定,并进行田间温、光、风速和CO_2浓度的观测,结果表明,套种优于清种,而套种中又以宽行套种方式最佳,适于套种的小麦品种为永良四号,大豆有榆林大豆、铁丰八号等品种。
Wheat field intercropping Soybean is an irresponsible natural resource with drought and no rainfall, short frost-free period and economic utilization - an important way for light, water and heat to win high yield. However, the key to obtaining the ideal economic benefits lies in choosing a good variety and determining the reasonable proportion of interplanting. For this reason, a series of physiological indices such as dry weight, leaf area index, net photosynthetic rate and chlorophyll content were measured during the main growth stages of wheat during the three years of experiment. Temperature, light, wind speed and CO2 The results showed that the intercropping was better than the intercropping, while the intercropping was the best by wide intercropping. The intercropping wheat varieties were Yongliang No.4 and the soybeans had the varieties of Yulin Soybean and Tiefeng No.8.
