豫北地区18个秋播饲用燕麦品种抗倒伏特性及生产性能评价
Lodging resistance and production performance of 18 autumn-sown forage oat varieties in northern Henan Province
摘要
Abstract
The aim of this study was to compare the lodging resistance and production performance of 18 autumn-sown forage oat (Avena sativa) varieties in northern Henan Province.A field study was conducted to determine the lodging incidence at different growth stages,hay yield,tillering characteristics,and winter survival of 18 oat varieties.Then,the relationships between lodging and plant height,ear height,and stem morphology were evaluated.The results showed that:80％ of oat varieties began to show lodging from the heading stage,and the lodging incidence ranged from 10％ to 95％ at the mid-milk maturity stage.Among the 18 varieties,'Baler' and 'Millionaire' had the lowest lodging incidence.The lodging incidence was negatively correlated with stem morphological indexes including stem base diameter (1st and 2nd internode diameters) and 2nd internode dry weight (P<0.05).The 18 varieties were able to complete the entire growth and development process in the experimental area,and the growth period ranged from 182 to 207 days.Among the 18 varieties,the number of tillers at the greening stage,hay yield,plant height,and winter survival rate ranged from 5.3 to 8.5 per plant,11.99 to 20.46 t·ha-1,1.11 to 1.52 m,and 83.7％ to 96.6％,respectively.The hay yields of 'Baler','Everleaf',and 'Forage Plus' were significantly higher than those of other varieties,and the hay yield of these three varieties exceeded 20 t·ha-1.Based on a multivariate evaluation of lodging resistance,hay yield,and nutritional quality,'Baler','Forage Plus',and 'Millionaire' were identified as suitable varieties for autumn sowing in northern Henan Province.关键词
