湘潭县超级稻—再生稻示范种植效益分析

摘要

为探讨超级稻—再生稻在湘潭的推广应用前景,以‘深两优5814’与‘隆两优华占’为材料,在湖南湘潭县开展了较大面积的超级稻—再生稻示范种植.结果表明:超级稻头季产量为9900 ～ 10 650 kg/hm2,再生季产量可达3300 ～ 3735 kg/hm2;头季与再生季成本分别为9288和1950元/hm2,两季总纯收入为26 697～27 417元/hm2,较一季超级稻增收40.84％ ～53.06％.可见,超级稻—再生稻增产增收效果显著,且具有良好的社会效益与生态效益,在湘潭地区具有广阔的推广应用前景.%In order to explore the application prospect of super rice-ratooning rice in Xiangtan county,large area demonstration planting of super rice-ratooning rice was carried out in Xiangtan county,Hunan province,with the varieties of Shenliangyou 5814 and Longliangyouhuazhan.The results showed that:the yield of main crop of super rice reached 9900 ～10 650 kg/hn2,and that of ratooning rice was 3300 ～ 3735 kg/hm2.The costs of main crop and ratooning rice were 9288 Yuan/hm2 and 1950 Yuan/hm2 respectively,and the net income of super rice-ratooning rice reached 26 697 ～27 417 Yuan/hm2,which was higher than that of one season super rice by 40.84％ ～ 53.06％.So super rice-ratooning rice increased yield and benefit significantly,and favorable social and ecological benefit,there is a wide generalization and application prospect in Xiangtan area.
