肥田萝卜是一种十字花科冬季绿肥,在我县有着悠久的栽培历史,直至六十年代中期,仍是我县主要冬种绿肥之一。近十多年来,随着红花草播种面积的逐年扩大,肥田萝卜的种植面积才逐渐缩小。但由于它具有耐寒,耐旱、耐酸、耐瘠、适应性和冬发性强、耐迟栽、容易栽培等特性,全县每年还有二万亩左右水源缺乏的山排田和冷浸性低产田种植,占常年绿肥面积的10—20％,一般亩产鲜草一、二千斤,有的高达三、四千斤,是我县历年来扩种绿肥,消灭冬闲田的一项有效措施。 Feitian radish is a cruciferous winter green manure, in our county has a long history of cultivation, until the mid-sixties, is still my county one of the main winter green manure. In the recent ten years, with the sowing area of ​​safflower growing year by year, the acreage of fattened radish was gradually reduced. However, due to its characteristics of cold resistance, drought tolerance, acid resistance, barren resistance, adaptability and winter-harshness, long-term planted and easy cultivation, the county still has about 20,000 mu of scarce water fields and cold-soaked fields every year The cultivation of low-yielding fields accounts for 10-20% of the perennial green manure area. Generally, one or two kilos of fresh grass per mu is produced, while some three or four kilos of them are uplifted. Measures.
