高海拔冷凉气候区胡萝卜高效栽培技术研究

Study on Cultivation Techniques of Carrot in High-altitude Cold Area

在甘肃河西走廊沿祁连山高海拔冷凉气候区开展了胡萝卜种植密度、播种时期及平衡施肥的技术研究,结果表明,该区域胡萝卜最佳种植密度为10cm×15cm;播种期和出苗期的气温在10℃以上为佳;N,P,K平衡施肥(尿素450kg/hm2、过磷酸钙750kg/hm2、硫酸钾300kg/hm2)可使胡萝卜植株生长健壮,商品性状好,产量高,效益好。

The cultivation techniques of carrot, including density, sowing date and balanced fertilization of carrot in Hexi corridor in Qilian Mountain high-altitude cold area were studied. The results indicated that the best planting distance is 10 cm×15 cm. The seed of carrot could be sowed when temperature is higher than 10℃. The balanced fertilization is carbamide of 450 kg/hm2, Ca （H2PO4）2 of 750 kg/hm2, K2SO4 of 300 kg/hm2. The plant growth, quality of fruit,yield and economic benefit were improved.
