| |
Abstract: | In order to enrich the forage grass resource in Longdong region and to screen the silage maize variety with superior performance in this region, a total of ten varieties of silage maize were introduced. Using a commonly cultivated silage maize variety in this region as control, the agronomic traits, grass yield and nutritional composition contents of the introduced varieties were determined, and the resistance of these varieties was evaluated. The results showed that the varieties of Dongdan No. 11, Ruide No.1 and Dunqingzhu No. 28 had longer hold-green period of blade and higher grass yield, crude protein content and crude fat content, indicating that these varieties had good adaptability to the climate and soil environment of this region. |
