南疆地区复播制干辣椒栽培试验

Experiment of Multiple Sowing of Dried Chilli in South of Xinjiang

冬小麦收获后复播制干辣椒栽培模式能够充分利用光热资源,增加复播指数,提高效益。在喀什地区莎车县对早熟品种美国红植干椒、墨西哥甜椒、铁板椒等制干辣椒进行了育苗、果树行间麦茬后复播试验。结果表明,复播的3个早熟品种均表现出较好的产量收益,美国红植干椒表现出良好的产量潜力,辣椒素含量较高;墨西哥甜椒的单株结果数较多,单果重高,但成熟期较晚。其它两品种熟性较早。通过试验研究证明,复播制干辣椒夏季育苗移栽技术的要点主要是,适时播种、移栽,苗期气温回升时的肥水管理及病虫害管理。根据产量、品质及生育期调查结果,美国红植干椒是适于复播的最佳早熟品种,麦茬复播可充分发挥此品种生育期短、集中成熟、产量高等优良特性,可作为南疆复播制干辣椒的首选品种。

The multiple cropping system of winter wheat of high yield cultivation model of dry chili can make full use of heat resources, increase the index of multiple cropping, and improve the efficiency. This study had explored a set of key technology of the multiple cropping system of dry chili suitable for Kashi area in south of Xinjiang, it has better promotion value, and success in the experiment of fruit row cropping system of dry chili in Shache County of the Kashi area in 2012. The resulted showed that it had a better yield at the three early-maturing varieties which had been selected, the variety of United States＂ red planting pepper showed good yield potential, and Mexico＇s pimento had good performance in number of single fruit, the single fruit weight showed the characteristics of big fruit, but late maturity. The other two varieties showed better in maturity.
