摘　　要：为了研究春箭筈豌豆的生长发育和营养变化动态规律,了解其最佳刈割期,以春箭筈豌豆5-1-5品系为材料,研究了春箭筈豌豆株高、生长速度、物质积累、产量组成及其构成因子的变化规律,并对其营养价值进行了评定。结果表明,春箭筈豌豆生长动态符合Logistic模型,苗期生长缓慢,分枝后期-现蕾期生长最快,是营养体产量形成的关键时期;生物量和茎/叶比值,从分枝后期开始逐渐增加,但适口性和营养价值降低;鲜草和干草产量分别在结荚期和成熟后期达到高峰,结荚期鲜草产量、CP、CA、CF、EE、NFE、TDN产量分别为17.2、0.5、0.33、1.29、0.11、2.17、2.73 t/hm2;成熟后期干草产量、CP、CA、CF、EE、NFE、TDN产量分别为4.71、0.41、0.34、1.40、0.10、2.49、2.83 t/hm2。综合分析认为,播种后76-88天左右是春箭筈豌豆的最佳刈割期。在饲草实际生产中,春箭筈豌豆应在开花至结荚初期进行收割。The aims were to study the dynamics of growth and nutritional changes of Vicia Sativa, and obtainthe optimal clipping period. Vicia Sativa 5-1-5 was used as the sample, the changes of plant height, growthrate, material accumulation, yield components and its compositions were studied. The nutrition value was alsoassessed. The results indicated that the dynamic growth of Vicia Sativa fit the Logistic model. The growth ratewas slow in the seedling stage, and became the fastest from the branching-later stage to squaring stage, it wasthe critical period of vegetative forming. Biomass and the ration of stem to leaf increased gradually in thebranching-later stage, but the palatability and nutritive value declined. The fresh matter and the dry matterreached the maximum in the fruiting period and the mature-later stage, respectively. The fresh matter in thefruiting period, CP, CA, CF, EE, NFE, TDN was 17.2, 0.5, 0.33, 1.29, 0.11, 2.17, 2.73 t/hm2, respectively. Thedry matter in the mature-later stage, CP, CA, CF, EE, NFE, TDN was 4.71, 0.41, 0.34, 1.40, 0.10, 2.49, 2.83 t/hm2, respectively. In summary, 76-88 days after sowing was the optimal clipping period. It was suggested thatVicia Sativa should be harvested in blooming stage or fruiting-early stage in the practice.
