摘要: 滴灌条件下,为探索天山北坡无霜期为155-168d大于等于10℃的积温3110℃~3500℃的区域, 2015-2016年在第六师农科所试验地以生育期为80-85d的糯玉米为前茬作物研究对象,研究了糯玉米+雪里蕻、糯玉米+快菜、糯玉米+秋萝卜复播模式及最佳种植密度,并对三种复播蔬菜的平均产量、产值和效益进行分析比较。结果表明, 两年试验表明复播雪里蕻平均产量、产值和效益极显著,两年复播快菜的平均产量、产值和效益显著,说明糯玉米鲜穗收获后,复播三种蔬菜的产量、产值和效益排序是雪里蕻﹥快菜﹥秋萝卜。结论是天山北坡实现糯玉米复播蔬菜的高产高效模式,是糯玉米+雪里蕻,纯收入为47767.09元/hm2:糯玉米种植最佳密度是75000株/hm2,复播雪里蕻种植最佳密度为63000株/hm2

Abstract: The aim is to explore areas with≥10℃ accumulated temperature of 3110℃-3500℃ in the northern slope of Tianshan Mountains in 155-168 days of frost free period under drip irrigation. From 2015 to 2016, in experimental field of the Sixth Division of Agricultural Science Research Institute, waxy corn with 80-85 days growth period was used as preceding crop, potherb mustard, Chinses cabbage and autumn radish were used as resowing vegetables. The resowing models (waxy corn + potherb mustard, waxy corn + Chinses cabbage, waxy corn+autumn radish) and the optimum planting density were studied. The average yield, output and benefit of the three resowing models were analyzed and compared. The results showed that two years’continuous sowing of potherb mustard or Chinses cabbage had significantly different average yield, output and benefit. The yield, output value and benefit of resowing of the three vegetables followed an order of potherb mustard> Chinses cabbage>autumn radish. The high yield and high efficiency model of resowing vegetable in waxy corn field is waxy corn + potherb mustard, the net income is 236.32 yuan/m2. The optimum planting density of waxy corn is 7.5 plants/m2, and the optimum planting density of resowing potherb mustard is 6.3 plants/m2.
