摘要:在甘肃省农业科学院张掖节水农业试验站对4个干制辣椒品种进行了引种试验。结果表明,以天椒13号鲜重折合产量最高,为36 264.7 kg/hm2,较对照品种线三增产42.38%;天椒15号次之,鲜重折合产量为33 600.00 kg/hm2,较对照品种线三增产31.92%;凯旋8号居第3位,鲜重折合产量为 33 264.7 kg/hm2,较对照品种线三增产30.60%。制干率以凯旋8号最高,达到15.30%,较对照品种线三增加0.98百分点;天椒15号次之,为14.60%,较对照品种线三增加0.28百分点;天椒16号制干率略低,为14.22%,较对照品种线三减少0.10百分点。综合考虑,天椒13号长势强,果实商品性好,坐果最多,折合产量最高,增产幅度最大,可作为河西地区干制辣椒主栽品种。天椒15号和凯旋8号产量较高,增产幅度大,制干率也高,可作为配套品种。

Abstract:In this experiment, 10 wheat varieties(Strains) with better planting performance in longzhong semi-arid area were selected for the analysis of yield, WUE and drought-resistance index and some agronomic traits in recent years.The drought-resistance of each variety(Strains) and the optimum planting area  with the above mentioned indexes were evaluated. With the increase of irrigation amount, the plant height of all tested wheat varieties(Strains) increased. The lodging area of wheat varieties longzhong no. 4 and longzhong no.1 reached 32.6% and 40.7%, repectively, and the yield of zhongmai 175 reached 5 531.0 kg/hm2 under the T3 treatment. The varieties with third level for drought resistance index including longzhong no.5, CA13012 and 200833-3 and 200917-2. According to the comprehensive analysis for yield, WUE, drought-resistant index and lodging area, the varieties(Strains) suitable for planting in the area with rainfall of 350~550 mm including longzhong no.4, longzhong no.5, CA12003, longyu no.10, 200707-2-2.The varieties (Strains) suitable for planting in the region with rainfall of 350~650 mm are:CA13012, 200833-3, 200917-2.The variety wheat zhongmai 175 should be planted for the area with rainfall in 450~650 mm.

近年来,全国范围内辣椒加工产品日益畅销,干制辣椒种植面积越来越大,干制辣椒对提高农民收益的贡献日益增大[1 ]。由于生产的干制辣椒产量高、品质好、色价高、供期长,甘肃正逐步成为国内最大的干制辣椒生产基地[2 ]。目前,甘肃省干制辣椒种植面积约6 670 hm2[3 ],其种植区主要分布在河西走廊地区,主栽品种有美国红、线三 等[4 ],辣椒鲜重产量为30 000 kg/hm2,产值 45 000 元/hm2左右[5 ]。为了提高河西地区干制辣椒的产量和品质,甘肃省农业科学院张掖节水农业试验站于2019年对引进的4个干制辣椒品种进行了品种比较试验,旨在筛选出适宜河西地区栽培的干制辣椒品种,现将結果报道如下。……
