Determination method for content of acid detergent fiber in Lolium multiflorum

Abstract

The invention discloses a c capable of rapid determination of the content of acid detergent fiber in Lolium multiflorum. The determination method provides a prediction model for the actual content of the acid detergent fiber in Lolium multiflorum based on near infrared spectroscopy; the quantitative analysis and prediction model for the content of the acid detergent fiber in Lolium multiflorum based on near infrared spectroscopy and a chemometrics method is established by acquiring the original near infrared spectrum of a sample on the basis of known actual values of a great number of samples; a to-be-detected Lolium multiflorum sample is subjected to pretreatment so as to obtain the powder of the to-be-detected Lolium multiflorum sample; and the original near infrared spectrum of the powder is acquired, the process of spectrum acquisition is short in time, and detection can be carried out after acquisition of the original near infrared spectrum. The Lolium multiflorum provided by the invention has the characteristics of simple operation, rapid detection, high detection efficiency, high detection precision and the like and is applicable to promotion and application in the field of evaluation of the nutritional quality of pasture.

Description

technical field [0001] The invention relates to the field of pasture nutritional quality evaluation, in particular to a method for measuring acidic detergent fiber content of Lolium multiflora. Background technique [0002] Multifloral ryegrass (Lolium multiflorum Lam.) is an annual or perennial forage grass belonging to the Gramineae ryegrass family. It is suitable for growing in warm and humid regions. It is one of the excellent forage grasses with world cultivation significance. There are large areas of cultivation. In recent years, with the adjustment of the national agricultural industry structure, herbivorous animal husbandry has developed rapidly. Due to its high yield, strong growth in winter and spring, strong adaptability, and rich nutritional value, ryegrass multiflora has solved the problem of livestock feeding in winter and spring in southern my country. The problem of insufficient grass has played an extremely important role in the crop rotation of grain and gr...

Problems solved by technology

At present, traditional wet chemical methods are mainly used for the determination of forage grass ADF in China. There are outstanding problems such as complex operation, large error, high cost, long time consumption, and environmental pollution caused by toxic and harmful chemicals. ) or samples to screen out the varieties (lines) or samples with appropriate ADF content, so finding out a method that can quickly measure the ADF content in Lolium multiflora is of great significance to the breeding of Lolium multiflora and the quality control of forage
