Scope

Scope: This standard specifies the terminology and definitions, mowing, drying, baling, and storage techniques, as well as quality grading in the production of African dogtail grass hay. This standard applies to the production of African dogtail grass hay. Main technical content: 1. Scope 2. Normative references 3. Terminology and definitions 3.1 African dogtail grass 3.2 Green hay 4. Mowing 4.1 Mowing time 4.2 Mowing stubble height 4.3 Mowing methods 4.4 Mowing frequency 5. Drying 5.1 Drying method: Use the method of drying in the field. When the fresh grass moisture content reaches 15% to 18%, it should be baled. 5.2 Drying time: From September to October, the African dogtail grass hay after mowing should be dried in the field for 5 to 7 days. During this period, avoid dew and turn over the hay for drying. When the hay makes a "rustling" sound or a "dry cracking" sound, the leaves curl up and the stems are easily broken, it can be baled and harvested. 6. Baling Baling operations should avoid morning dew. Generally, baling should start after 10 a.m. During the baling process, it is necessary to carefully observe whether the hay feeding is uniform and whether the knotter is working normally. During the baling process, the baler must be refueled with butter once every 8 to 10 hours. Use square balers to compress the loose African dogtail grass into square bales. The square balers should comply with the requirements of GB/T 25423. The safety and quality of the bales should comply with the requirements of NY/T 2463 or NY/T 1631. The density of the square bales should be higher than 75 kg·m-3, and the dimensions of the bales are: length × width × height = 80cm × 46cm × 36cm. According to the drying degree of the green hay, the density of the bales can be increased for the drier hay, and vice versa, the density of the bales can be reduced appropriately. 7. Storage The storage conditions of the bales should comply with the requirements of NY/T 1177. When the moisture con
