选取燕麦品种、播期、播量、行距四个因子,每个因子取四个水平进行正交试验,研究燕麦籽实、秸草、青割草三项产量与各因素、水平的关系。结果表明:在我国北方自然气候条件下,适时早播是获得料、草高产优质的关键措施。同时要注意选用良种与合理密植,才能达到高产优质的目的。 Four factors of oat variety, sowing date, seeding rate and row spacing were selected. Four factors were taken for orthogonal experiment. The relationship between the three yield of oat seed, straw and mulch was studied with the factors and levels. The results showed that: under the natural climate conditions in northern China, timely sowing is the key measure to obtain high yield and quality of material and grass. At the same time pay attention to the selection of seeds and reasonable density, in order to achieve the purpose of high yield and quality.
