夏播5个饲用甜高粱品种在西辽河平原灌区的生产性能评价
Evaluation of production performance of five Sorghum saccharatum Moench varieties sown in summer in irrigation area of West Liaohe Plain
摘要
Abstract
The experiment was designed to evaluate the production performance of five Sorghum saccharatum Moench varieties under summer planting in the irrigation area of West Liaohe Plain.In order to select suitable Sorghum saccharatum Moench varieties for planting in the irrigation area of the West Liaohe Plain,the study adopted a randomized block design to measure the agronomic traits,yield,and nutritional quality of five Sorghum saccharatum Moench varieties.The production performance of the five Sorghum saccharatum Moench varieties was comprehensively evaluated using correlation,principal component,and membership function analysis.The results showed that the stem diameter,leaf area,and fresh forage yield of Liaotian No.1 were significantly higher than those of Jinmu No.1,Jinmu No.4,and Tongtian No.1(P＜0.05),and there was no significant difference compared with Beitian C4(P＞0.05).The plant height of Beitian C4 was significantly higher than that of other varieties(P＜0.05),and the concentrations of acid detergent fiber and neutral detergent fiber of Liaotian No.1 were both significantly lower than those of Beitian C4(P＜0.05),the crude protein content of Beitian C4 was significantly higher than that of other varieties,at 14.54%(P＜0.05),and the relative feeding value of Jinmu No.1,Jinmu No.4,and Liaotian No.1 was significantly higher than that of Tongtian No.1 and Beitian C4(P＜0.05).Correlation analysis indicated that fresh forage yield was significantly positively correlated with stem diameter(P＜0.05),and the content of neutral detergent fiber was extremely positively correlated with plant height(P＜0.01).Twelve indicators,including plant height and stem diameter,were transformed into three comprehensive indicators through principal component analysis,with a cumulative contribution rate of 96.95%.Based on the principal component analysis,the membership function comprehensive analysis of the tested varieties showed that the scores from high to low were Liaotian No.1＞Beitian C4＞Tongtian No.1＞Jinmu No.4＞Jinmu No.1.The study showed that Liaotian No.1 has high forage yield and quality,and is suitable for planting in the irrigation area of West Liaohe Plain.关键词
