头季稻—再生稻—马铃薯水旱轮作种植模式

Water and Drought Rotation Mode of Early Rice-Ratoon rice-Potato

为提高土地产出率,2020年以早稻作为头季稻,开展头季稻、再生稻和冬马铃薯品种水旱轮作种植模式试验。结果表明:头季稻每667m^(2)产量以农优90最高,达496.7 kg,比佳辐占(CK)显著增产7.19%;再生季每667m^(2)产量也以农优90最高,达328.3 kg,但与CK差异不显著。冬马铃薯每667m^(2)产量以闽薯1号最高,达3 278 kg,比费乌瑞它(CK)显著增产14.22%。分析农优90和闽薯1号品种组合的头季稻-再生稻-马铃薯水旱轮作种植模式的效益,每667m^(2)纯利润达4 322元,说明选择适宜的品种搭配,对推广头季稻-再生稻-马铃薯水旱轮作种植模式具有广阔前景。

Rotation mode of early rice-ratoon rice-potato was test in 2020 to improve land productivity,result showed that in main-crop season Nongyou90 obtained the highest yield of 496 kg per 667 m^(2),an increase by 7.19%over that of Jiafuzhan(CK),and also highest yield of 328.3 kg per 667 m^(2) in ratoon crop season,but was not different from yield of CK.The potato yield of Minshu1 was highest,and reached 3278 kg,a significant increase by 14.22%than that of Feiwuruita(CK).The overall profits of rotation mode with the cultivars of Nongyou 90 and Minshu 1 was 4322 yuan per,the test proved that this rotation mode combination with proper variety would be broad prospect.
