黄河中游南岸盐碱地饲用高粱生产性能综合评价
Comprehensive evaluation of production performance of forage sorghum cultivated on saline-alkali land along south bank of the middle Yellow River
摘要
Abstract
The experiment aimed to screen suitable forage sorghum varieties for cultivation in saline-alkali land along the south bank of the middle Yellow River and determine the optimal harvest period.Three widely used forage sorghum varieties were selected to analyze their agronomic traits,nutritional quality during the heading stage,milky stage,and wax ripening stage,with a comprehensive evaluation conducted using the grey correlation method.The results showed that the forage sorghum variety 3701 exhibited the strongest lodging resistance,the leaf width(5.99 cm),leaf number(10.30),dry-to-fresh ratio(0.40),stem-to-leaf ratio(2.08),dry grass yield(24 905.04 kg/hm2),fresh grass yield(61 986.53 kg/hm2),soluble sugar content(9.56%),and crude fat content(1.35%)were significantly higher than those of Tangbao and Jiebao(P<0.05),its concentrations of acid detergent fiber(29.15%),total potassium(11.45%),and crude ash(4.07%)were significantly lower than those of Tangbao and Jiebao(P<0.05).During the wax ripening stage,the stem diameter(12.66 cm),leaf number(9.20),dry-to-fresh ratio(0.43),dry grass yield(23 227.15 kg/hm2),and the concentrations of soluble sugar(9.88%),soluble starch(21.95%),crude fat(1.23%),and tannin(≥1.20%)of all varieties were significantly higher than those in the heading stage and milky stage(P<0.05),while the concentrations of neutral detergent fiber(45.77%),total potassium(9.42%),and crude ash(4.08%)were significantly lower than those in the heading stage and milky stage(P<0.05).The study shows that forage sorghum variety 3701 had a better overall production performance and is more suitable for promotion and cultivation in saline-alkali land along the south bank of the middle Yellow River and similar regions.For fresh forageing or dry grass production,harvesting during the wax ripening stage is recommended,while for silage,harvesting during the milky stage is advisable.关键词
