间作模式对棉花、花生产量及品质的影响

Intercropping Mode Affecting Yield and Quality of Cotton and Peanut

为了研究不同间作模式对棉花和花生产量、品质、总产值的影响,进而确定其在生产实际中的可行性。本试验设计了棉花-花生的5个间作模式,即棉花-花生3-1、2-1、1-1、2-2、1-2,清种棉花(CK1)、清种花生(CK2)为对照。结果表明:(1)各处理单位面积上的产值3-1处理最高,其次为2-1处理。(2)1-2处理棉花的果枝数、单株铃数、铃重、子指、衣分、霜前花率最高,且棉花纤维品质最好。(3)1-2处理花生的单株饱果数最高。(4)CK2的产量构成因素最高,果仁含水量最低。综合来看,3垄棉花-1垄花生、2垄棉花-1垄花生的间作模式可以有效提高群体经济效益,同时还提高棉花的纤维品质,两者可以在生产中推广应用。

The study aims to assess the influence of different intercropping modes on yield, quality and totaloutput of cotton and peanut, and then determine the feasibility of these modes in production practice. The testdesigned 5 intercropping modes： cotton-peanut 3-1, 2-1, 1-1, 2-2, 1-2, cotton（CK1） and peanut（CK2）. Theresults showed that：（1） the highest output value per unit area came from 3-1 treatment, the second came from2-1 treatment;（2） 1-2 treatment had the highest number of cotton branch, boll number, boll weight, seedweight, lint, lint before frost, and the cotton fiber quality was the best;（3） 1-2 treatment had the highest peanutfull pods number per plant;（4） CK2 had the best yield components with the lowest seed water content. Takentogether, intercropping mode of 3-ridge cotton and1-ridge peanut, 2-ridge cotton and1-ridge peanut canimprove the population economic benefits, while enhance cotton fiber quality, both the two modes can berecommended in production practice.
