Adaptability evaluation of forage oat varieties in Ar Horqin Sandland
To select special forage oat (Avena sativa) varieties suitable for planting in the Ar Horqin sandland, the plant height, flag leaf length and width, stem diameter, hay yield, and nutritional quality of thirteen spring sowing oat varieties and twelve summer sowing oat varieties were measured using the field randomized block design test method. The fuzzy mathematics membership function method was used to conduct a comprehensive analysis of each index. Results showed certain differences in production performance and nutritional quality indicators between different spring- and summer-sowing oat varieties. The membership function values of different spring-sowing oat varieties were sorted in the following descending order:'Fuyan No.1' >'Beili' >'Tianyan No.1' >'Aibo' >'Hanma' >'Haiwei' >'Menglong' >'Surui' >'Monica' >'Heimeike' >'Sanxing' >'Kaisa' >'Temu'. The membership function values of different summer sowing oat varieties are sorted in the following descending order:'Tianyan No.3' >'Menglong' >'Hanma' >'Surui' >'Tianyan No.2' >'Tianyan No.70' >'Haiwei' >'Aibo' >'Samo' >'Kaimo' >'Tianyan No.75' >'Fuxing'. The above results showed that the varieties of oats suitable for spring planting in Ar Horqin sandland were 'Fuyan No.1', 'Beili', and 'Tianyan No.1' while the varieties of oats suitable for summer planting in Ar Horqin sandland were 'Tianyan No.3', 'Menglong', and 'Hanma'.
