| In this experiment, four cultivars of oats: Baiyan5, Bayou1, Dancer and Shadow weresown at October1,2011and March28,2012in the Guanzhong area. The oats sown inautumn was mown in winter for first time, and after winter we cut the renewable forage; Theoats seeded in spring was mown in the summer. The objective of this research was to find outthe optimal oat cultivar and mown stage according to the analysis of their yield and quality, inorder to explore the utilization of oat forage in the Guanzhong area. The results are as follows:1. Oat sown in autumn can grow under natural low-temperature environment in winter,bayou1which was from Hebei province yield0.63kg/m~2fresh forage and the content of crudeprotein was19%DM., So it has a important practical significance for animals as winterfeeding diets;2. Oats sown in the fall, can be mown for times. Effect of varieties and mown stages onthe yield and quality of the oats were significant. After winter the reviving forage mown in60days, the maximum fresh yield of bayou1was3.5kg/m~2, but the content of crude fiber up to30%DM, the quality was slightly worse than the first cut of grass; Third time mow grass in30days, the quality was similar to the second cut and fresh weight was up to0.89kg/m~2.3. The spring oat can grow up in a short time, provding a high-yield and good–qualityforage, but the effect of high-temperature climate should be noted in oat’s growing period.Cut Shadow in80days after sown can ensure the yield and quality of oat forage. |
