摘要
采用完全随机试验设计 ,研究不同修剪次数、修剪高度对新疆狗牙根种子生产性能的影响。结果表明 :不同的修剪次数对新疆狗牙根种子产量影响显著 (P <0 .0 5 ) ,且以修剪一次种子产量为最高 ,达 72 3.9kg·hm- 2 ,比对照提高 69.2 5 %。不同修剪高度对新疆狗牙根种子产量影响极显著 (P <0 .0 1)。在分蘖—拔节期 ,修剪留茬 3cm可获得最高的种子产量 ,为 5 71.3kg·hm- 2 ,比对照提高 33.5 7%。
Effect of different frequency and heights of mowing on seed productive property of Xinjiang Bermudagrass was studied. The results indicated different frequency of mowing made a notable impact on seed productive ability(P<0.05)and one time was best and seed yield was 723.9 kg·hm -2 , 69.25% more than CK. Different heights of mowing had great effect on the seed yield of Xinjiang Bermudagrass(P<0.01)during tiller stem elongation period. In all treats, the best was 3 cm height sand seed yield was 571.3 kg·hm -2 , 33.57% more than CK.
