| 摘 要： | 刈割期是影响白三叶种子产量和草产量的主效因子;间隔期越短,白三叶在总产草量中所占比例越高;留茬过高(10 cm)或过低(5 cm)、间隔期过长(45 d)或过短(15 d)均对种子生产不利;其中以30 d-8 cm种子产量最高(412.9kg/hm2),极显著高于其余处理(p＜0.01),且杂草量少、干草产量4505.3 kg/hm3,品质高,其中白三叶所占比例为46.97%;15 d-0 cm干草产量最高(11011.4 kg/hm2);15 d-5 cm白三叶干草产量最高(4422.1 kg/hm2).

| Abstract: | White clover(Trifolium repens L.) seed yields and herbage production were studied on white clover seed-breeding fields under 9 treatments assembled with 5,8 or 10 cm stubble height and 15,30 or 45 d cutting interval along with zero cutting during summer and autumn.Cutting increased the proportion of white clover in the field,enhanced the seed yields and herbage production of white clover.Cutting interval was a main factor for herbage production,the shorter the interval was,the higher were the harvests of white clove and weeds,the total harvests,and the white clover proportion.Both of stubble height and cutting interval affected seed yields,extreme stubble height(5 cm or 10 cm) and cutting interval(15 d or 45 d) were disadvantageous for the seed production.The treatment with 30 d-8 cm resulted in highest seed yield of 412.9 kg/hm2(P<0.01),least weeds harvest,herbage production of 4505.3 kg/hm2,highest herbage quality,and white clover proportion of 46.97%.The highest total herbage production of 11011.4 kg/hm2 was obtained under treatment of 15 d-10 cm;treatment of 15 d-5 cm resulted in the greatest whiter clover herbage production of 4422.1 kg/hm2. |
