“秋繁春种”马铃薯种薯的产量及经济效益

Yield and Economic Benefit of Potato Propagated in Autumn and Sowed in Spring

2009年在黔南高海拔(1050m)地区,进行了相同马玲薯品种费乌瑞它3个不同产地薯种的产量和经济效益比较试验。结果表明:呼伦贝尔种薯产量最高,但种薯价格高,经济效益低;经济效益最好的是黔南三都县繁育的种薯,产量较高,种薯价格低;贵州西部平坝县种薯产量最低,经济效益差。说明在本地低海拔地区秋季繁种,次年春季在高海拔地区种植的方法,在黔南马玲薯生产上有广泛的应用前景。

A test of the yield and economic effect of same potato variety Favorita but 3 different production place seeds was conducted at the high elevation（1 050 m） area of the southern part in Guizhou Province in 2009.The results showed that the highest yield was Hulun Buir seed with high price and low economic benefit;the highest economic benefit was Sandu seed with higher yield and low seed price;the lowest yield was Pingba seed with low economic benefit.There is extensive application prospect for the southern part of Guizhou Province to this method of the potato seed propagated in autumn from local low elevation area and sowed in the next spring at high elevation area.
