干旱缺水对陇中旱作区饲草型小黑麦产量及营养品质的影响
Effects of Drought and Water Shortage on the Yield and Nutritional Quality of Forage Triticale in Longzhong Dry Farming Areas
摘要
Abstract
The effects of drought and water shortage on the biological yield and nutritional quality of forage triticale were studied to select high yield,high quality and drought-resistant triticale varieties suitable for planting in Longzhong area.Four triticale varieties(lines)were used as experiment materials,the effects of normal water supply and drought on the fresh yield,hay yield and nutritional quality of triticale were determined,respectively.Results showed that compared with normal water supply treatment,drought and water shortage significantly decreased the yield of fresh grass,hay,crude protein content and ether extract content by 25.25％to 29.71％,23.82％to 29.19％,23.99％to 30.41％,and 20.42％to 29.55％,respectively.Crude fiber content,neutral detergent fiber content and acid detergent fiber content were significantly increased by 16.42％to 22.05％,7.14％to 9.95％,and 11.61％to 16.63％,respectively.There were significant differences among different triticale varieties(lines).According to the comprehensive evaluation,varieties(lines)3297 and 5 Quan 50 showed better performance in forage fresh yield,hay yield and nutritional quality,which was suitable for demonstration and promotion in arid and semi-arid areas of Longzhong.关键词
