Lesson 9 Forage Production Part A Forage Establishment Field selection Suitable forage species are available for all types of Manitoba soils and moisture conditions. Use Table 9-1 and Table 9-2 as a guide for selecting hay and pasture forages for different soil conditions. Perennial weeds are difficult to control in seedling forages, and should be controlled before establishment. If conventional tillage practices are being used, prepare a fine, firm, shallow seed bed. Increasingly, forage growers are successfully establishing forage stands without tillage. Benefits of zero-tillage forage establishment are:1 lower costs and less labour; 2 better seed bed moisture conservation; 3 standing dead mulch protects an emerging crop from drying-out and sandblasting. 合适的牧草品种可用于马尼托巴湖所有类型的土壤和水分条件。使用表9-1和9-2 作为选作物不同土壤条件的干草和牧场牧草的指南。 牧草幼苗期的多年生杂草很难控制，应当在建立前控制，如果使用常规实践，准备一个精细，坚定，浅的种床 ，逐渐的 ，牧草种植者成功的建立了无耕作的饲料站。零耕作牧草建立的利益是1.降低成本和低的劳动力2.更好地保持种床水分，3.长期有效的死物质覆盖保护作物免受干旱胁迫和风沙的危害。 Seeding Inoculation Treating legume seeds with an appropriate inoculant ensures good nitrogen(N) fixation,and should be carried out before seeding. Inoculant contains living rhizobium bacteria, and must be handled carefully to ensure viability. Keep inoculant in the sealed original container, store in a refrigerator until required and do not expose to direct sunlight. Plant immediately after inoculation. If seeding is interrupted, store seed in a cool, dark place and resume seeding when possible. Pre-inoculated seed is also available. Store seed in a cool, dark place to keep the inoculant viable. Each legume or group of legumes requires a specific species of rhizobium bacteria for N fixation. Ensure that the inoculant you buy is appropriate for the crop being seeded.
