近年来为提高粮食单产 ,增加农民种粮收入 ,积极推广再生稻生产技术 ,目前 ,年推广再生稻种植面积 10 0 0ｈｍ2 左右。由于受地理和气候影响 ,全县有冷浸田、烂泥田 2 0 0 0ｈｍ2 以上 ,这类田再生稻单产比其他稻田低 2 0～ 30 %。对此 ,我们借鉴安徽等省水稻地膜栽培技术经验 In recent years, in order to increase grain yields, increase peasants’ income from planting grain, and actively promote the production technology of ratooning rice, at present, the area under cultivation for ratooning rice is about 10 000 hm 2. Due to the influence of geography and climate, the whole county has over 20 000 hm 2 fields of cold-dip fields and muddy fields, and yields of these ratoon rice varieties are 20-30% lower than those of other paddy fields. In this regard, we learn from Anhui and other provinces of rice cultivation techniques
