摘要/Abstract

摘要： 1992-1994年在亚热带低山区(四川芦山县)进行了填闲混播冬性一年生牧草与水稻轮作的经济生态效益的研究。结果表明,混播冬性一年生禾草和豆草与水稻轮作,即意大利黑麦草+紫云英→水稻、意大利黑麦草+南苜蓿→水稻和意大利黑麦草+白三叶草(营养体)→水稻三种轮作方式在水稻产量高于或稍低于对照(CK→R)但差异不显著的情况下,获得了高的饲料价值(TDOM 5.18-5.45t/hm²,CP 1.69-1.84t/hm²,ME 3.76-4.01×10⁴MJ/hm²)和良好的营养互补作用。填闲混播一年生豆、禾牧草提高了农田生态位的利用效率,改善了土壤结构和营养状况。

Abstract: This study was carried out at the subtropical low mountainous area of Lu-Shan County of Sichuan Province during the period of 1992 to 1994. The results showed that the three rotation systems of mixtures of annual grasses and legumes with rice i. e. Lolium multiflorum+Astragalus sinicus→rice, Lolium multi-florum+Medicago hispida→rice and Lolium multiflorum+Trifolium repens(vegetative propagation)→rice obtained a good forage value(TDOM 5.18-5.45 t/ha, CP 1.69-1.84 t/ha, ME 3.76-4.01×10⁴ MJ/ha) and mutual supplement of nutrition under the condition without singnificantly different of rice yields between the three treatments and check plots. The utilization effeciency of plant niche and the soil structure and nutritive condition in cropland have been increased by mixtures of annual grasses and legumes at winter fallow paddy field.
