| 摘 要： | 通过田间试验研究了鄱阳湖区免耕稻草覆盖、少免耕及常规栽培(CK)等模式下冬马铃薯生长特征、产量及经济效益的变化规律。结果表明:与对照相比,免耕栽培模式下(免耕稻草覆盖、少免耕)马铃薯表现出出苗早且生育期短的特征;免耕稻草覆盖和少免耕马铃薯的个体重量的变异系数较对照分别降低了0.13和0.08,同时分别节省用工67.5和37.5个工/hm2,增加纯收入分别达2610和1383元/hm2,分别提高经济效益12.8%和6.8%。

| Abstract: | Through field tests,the variation laws of growth characteristics,yield and economic benefit of winter potato in the Poyang Lake area were studied under the cultivation modes of no-tillage plus rice-straw mulching,few tillage,and traditional cultivation(CK).The results showed that: in comparison with CK,the potato cultivated by no-tillage plus rice-straw mulching mode and few tillage mode had the characteristics of earlier germination and shorter growth duration,the coefficient of variation of its weight per... |
