| Abstract: | Objective ] The research aimed to study the optimum sowing date of muhi-cropping forage rape after reaping wheat in northern al-pine regions. Method ] Using multi-cropping forage rape variety Huayouza 62 after reaping wheat as test materials, the effects of different so-wing date on its yield and quality were studied. Result] The plant height of Huayouza 62 sowed on July 15th increased 23 cm than that sowedon August 10th , and its yield increased 13.5 t/hm2 than that sowed on July 10th. The contents of K, Mg and P in Huayouza 62 sowed on July15th were 3 789. 0, 1 015.0 and 684.7 mg/kg respectively, which increased 381.0,427.0 and 196.9 mg/kg respectively than that sowed onJuly 10th. The heat quantity of Huayouza 62 sowed on July 15th was 2 699.1 KJ/kg, which increased 1 334.7 KJ/kg than that sowed on Au-gust lOth. The contents of crude protein, crude fat, carbohydrate and crude fiber in Huayouza 62 sowed on July 15th were 4.24% ,0.83% ,10. 02% and 2.98% respectively, which increased 2.32%, 0.5%, 4.53% and 2.33% respectively than that sowed on August 10th. Conclusion] Long term of light and temperature conditions was favorable for the accumulation of nutrients in forage rape and it had good edibility. |
