Abstract

Abstract:

Xudou 18 and Jiangyu 877 were used as experimental materials for soybean and maize strip compound planting, and the effects of different chemical control agents on yield, dry matter accumulation, nitrogen accumulation, lodging resistance, leaf area index and chlorophyll content (SPAD value) were studied. The results showed that the spraying of uniconazole and Yuhuangjin was better in improving the yield, land equivalent ratio and economic benefits of maize and soybean under strip compound planting. The dry matter accumulation of maize was the largest under the treatment of Yuhuangjin, and the maximum dry matter accumulation of soybean was under the treatment of uniconazole. The nitrogen accumulation of maize and soybean was increased the most by spraying robust hormone. Spraying robust hormone had a good effect on the comprehensive index of lodging resistance of maize, and spraying Jindele had a good effect on the comprehensive index of lodging resistance of soybean. The relative chlorophyll content of maize and soybean was higher under the spraying of Yuhuangjin, the leaf area index of maize sprayed with uniconazole was the highest, and the leaf area index of soybean sprayed with diethyl aminoethyl hexanoate was higher.

Key words: soybean, maize, chemical control agents, strip compound planting, yield
