我们自1998年开始引进试种韩国白玉春萝卜,经过几年的试种,产量和效益很好,每亩(1亩=667平方米,下同)萝卜的产量和产值分别达到3300千克和1368元。种植白玉春萝卜与种双季早稻不但没有季节矛盾,而且还能提高土壤有机质含量,培肥地力,可减少早稻基肥和追肥用量,早稻生长还优于对照田块。如果不种早稻种毛豆、西瓜等经济作物则更为有利。所以,利用冬闲稻田种植白玉春萝卜,是稻区结构调整的一种较理想模 Since 1998, we have introduced the trial of white radish radish in Korea. After several years of trial cultivation, the yield and benefits are very good. The yield and output of radish per mu (1 mu = 667 m2) are 3300 kg and 1368 respectively yuan. Planting white jade radish and double crop early rice not only do not have seasonal contradictions, but also improve soil organic matter content, fertility and fertility, can reduce the amount of base fertilizer and topdressing early rice, early rice growth is also better than the control plots. If not species of early rice soybean, watermelon and other cash crops are more favorable. Therefore, the use of winter paddy rice planting white jade spring radish, rice structure adjustment is a more ideal model
