大麦有一个最佳的播种时间,能使大麦各个生长阶段均处在最适宜的季节,以满足其生长、发育、结实的要求,获得较高的产量。本试验初步认为:1.大麦成熟期随播期的推迟而推迟,一般迟播三天成熟期推迟一天。2.株高随播期的推迟而升高,叶片数随播期的推迟而减少。3.每亩穗数随播期推迟而下降,每穗粒数随播期的推迟而增加。4.黄花叶病发病率随播期推迟而下降,条纹病发病率随播期的推迟而上升。5.产量水平以11月10日播种为界,随播期的提早或延迟而下降。6.大麦最佳播种期在11月10日左右。
Barley has an optimal sowing time, which can make barley at all stages of growth in the most suitable season to meet the requirements of its growth, development and robustness and achieve higher yield. This experiment initially considered: 1. Barley maturation delayed with the delay of sowing, delayed three days delayed general maturity. Plant height with the postponed and increased, the number of leaves decreased with the delay of sowing. 3. The number of panicles per acre decreased with the delay of sowing date, and the number of grains per panicle increased with the delay of sowing date. 4. The incidence of yellow mosaic decreased with the delay of sowing, the incidence of striped disease increased with the delay of sowing. 5. The yield level is sown on November 10 and falls as soon as the sowing date is delayed or delayed. 6. The best sowing time for barley is around Nov. 10.
