【摘要】 栽培密度是影响马铃薯产量和商品薯率的主要因子之一。为探寻冬种马铃薯主栽品种粤引85-38在广东的最适栽培密度,完善其商品化生产综合配套技术,通过比较6种不同栽培密度下(株距分别为18、20、22、24、26、28cm)粤引85-38的不同产量和商品薯率,发现其在广东冬种的最适栽培密度为株距20～24cm。更多还原

【Abstract】 Planting density was one of the major factor that influent the total yield and marketable yield of potato. In order to explore the best planting density for winter cropping of potato (Yueyin 85-38) and improve its integrated support technology for commercial production in Guangdong province, cultivation experiment under six planting densities ranging from 18 cm to 28 m was carried out. Results showed that the best planting density for this specie was 20 to 24 cm.更多还原
