摘要: 研究不同栽培措施对萝卜生产的影响，结果表明：试验条件下，播种太早或太迟，对萝卜生长都不利，“瑞雪”萝卜最适播种期应为9月25日至11月5日；利用地膜覆盖，萝卜地上部和地下部的生产速度明显提高，生育期提早，产量比露地提高了36.64%；每667 m²种植密度以6 500~7 500株为好。

Abstract: Effects of sowing time, plastic film mulching, and planting density on the growth characteristics and yield of Ruixue radish were studied. The results showed that,under the experimental conditions, sowing either too early or too late in a season was detrimental to the growth of the radish. The proper sowing time for Ruixue was between September 25 and November 5. Using plastic film for mulching significantly hastened the growth of the plant parts both above and under the ground. Thus, the growth period of Ruixuewas shortened and itsyield improved 36.64% over control (without the ground cover). And, at 6 500-7 500 plants per 667 m², the highest yield with extremely significant differencesamong all planting densities tested was achieved.
