摘要
在川北农区引进8个饲用燕麦品种进行筛选试验研究,测定其生育期、株高、茎粗、茎叶比和草产量。结果表明:饲用燕麦各品种在川北农区种植能够完成整个生育周期;株高、茎粗、茎叶比等生长性状因品种特性原因各不相同;不刈割全株收获的鲜草产量达2 334.50~5 022.51kg/667m^(2)、干草产量均超过700kg/667m^(2),经一次刈割后再全株收获的鲜草总产量达3 605.39~5 349.24kg/667m^(2)。梦龙和牧王综合表现优于其他品种,可在川北农区种植和推广。
An experiment was conducted to screen eight forage oat varieties introduced into the agricultural region of northern Sichuan,measuring their growth period,plant height,stem diameter,stem-to-leaf ratio,and forage yield.The results showed that the forage oat varieties could complete their entire growth cycle when planted in the agricultural region of northern Sichuan;growth traits such as plant height,stem diameter,and stem-to-leaf ratio varied among varieties due to their specific characteristics;the fresh forage yield for whole-plant harvest without mowing ranged from 2 334.50 to 5 022.51kg/667m^(2),with dry forage yields exceeding 700kg/667m^(2),and the total fresh forage yield after one mowing and subsequent whole-plant harvest was 3 605.39 to 5 349.24kg/667m^(2).Menglong and Muwang exhibited superior overall performance compared to other varieties and can be cultivated and promoted in the agricultural region of northern Sichuan.
