Effect of Cultivation Conditions on Growth and Yield of Radishes

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.
