为了研究花溪灰萝卜在贵州西北部高寒山区的适应情况,于2010—2012年在赫章县珠市乡开展花溪灰萝卜的适应性研究,试验采用灰萝卜与玉米套种的方式(2行玉米2行花溪灰萝卜)种植,进行生育期、产草量的测定并观测生长、抗性和病虫害情况。结果表明:7月上中旬播种的灰萝卜鲜草产量及种子产量均比8月下旬播种的高;品种中产量最高的为花溪灰萝卜,鲜草产量为113 790.75 kg/hm2,种子产量为3 454.05 kg/hm2。说明在黔西北高寒山区种植花溪灰萝卜的最佳时间是7月上中旬;花溪灰萝卜因其生育期较短,有利于茬口衔接,是黔西北山区冬闲田土季节性种草养畜的理想草种。
In order to study the adaptation of Huaxi durian radish to alpine mountainous area in the northwest of Guizhou province, the adaptability of Huaxi durian radish was carried out in Zhusheng Township, Hezhang County from 2010 to 2012. The experiment was conducted in the way of intercropping with radish and corn Line Huaxi gray radish) planting, determination of growth period, the amount of grass production and observation of growth, resistance and pests and diseases. The results showed that the fresh grass yield and seed yield of gray radish sowed in middle and upper July were higher than those sown in late August. The highest yield of cultivars was Huaxi durian radish. The yield of fresh grass was 113 790.75 kg / hm2 and the seed yield was 3 454.05 kg / hm2. Indicating that the best time to grow Huaxi gray radish in the northwestern mountainous area in northwestern Guizhou is the middle of July; the shorter growth period of Huaxi gray radish is conducive to the convergence of stubble, which is the ideal grass for seasonal grass planting in winter fallow fields in the northwest of Guizhou.
