夏秋胡萝卜栽培播期初探

Primary Study on Sowing Time of Carrot in Summer and Autumn Seasons

在海拔 1 46 0m的纳雍县山区进行夏秋胡萝卜播期试验。结果表明 ,夏秋栽培在 4月 30日前播种产量较高 (单产达1 5 6 7.5～ 2 0 35 .2kg/ 6 6 7m2 )、品质优、产值较高。随着播期往后推移 ,产量降低、品质下降。

The experiment for selecting the optimum sowing time of carrot was conducted in Nayong county at an altitude above 1460 meters in summer and autumn seasons. The results show that the carrot sown before 30, April has the higher yield(23 512.5～30 528.0 kg/ha), good quality and higher output value. The yield, quality and output value of carrot decrease with the lapse of (sowing) time after 30, April.
