摘要
通过生物多样性豆麦高中抗品种行比的试验研究,筛选出豆麦行比均以1:9模式为最佳组合。高抗品种行比每公顷产量达7740 kg,较对照1(净豆)增产27.72％,较对照2(净麦)增产13.16％。中抗品种行比每公顷产量达6292.5 kg,较对照1(净豆)增产35.54％,较对照2(净麦)增产26.74％。混栽可减轻病虫对豆麦的危害。斑潜蝇虫指高抗品种行比较对照下降8.49;叶斑病病指下降7.85,条锈病病指下降1.2。中抗品种行比斑潜蝇虫指比对照下降10.12;叶斑病病指下降7.4,条锈病病指下降3.76。此模式操作技术简单、管理方便、成本低,农户易接受,增产增收显著,建议在郊区大面积示范推广。
Experiment of row-ratios of inter-planting broad bean with high and moderate disease resistance wheat varieties was conducted. Results showed that all optimum row-ratios are 1:9 of broad bean inter-planted with different resistance wheat varieties. When broad bean was inter-planted with high resistance wheat variety at 1:9, the yield was 7 740 kg/hm2, increased by 27.72% and 13.16% compared with CK1 (net broad bean) and CK2 (net wheat) separately, when inter-planted with moderate resistance wheat variety, the yield was 6 292.5 kg/hm2, increased by 35.54% and 26.74% compared with CK1 and CK2 separately, which indicated that mixture cultivation was helpful to decrease the damage to broad bean and wheat caused by diseases and pests. Results also showed that in inter-plant of high resistance wheat with broad bean, the leaf miner and leaf spot indices of broad bean decreased by 8.49 and 7.85 separately, the yellow rust index of wheat decreased by 1.2, in inter-plant of moderate resistance wheat with broad bean, the indices of leaf miner and leaf spot decreased by 10.12 and 7.4 correspondingly, the yellow rust index decreased by 3.76. This pattern of mixture cultivation is simple in operation and cost, significant in yield increase and easy to be accepted by fanners. It is suggested to extend in the suburb of Kunming on larger area.
