试验在湖南农业大学耘园试验基地进行,以湘花2008为试验材料,以露地播种为对照,研究覆膜＋遮阳对湖南夏播花生植株干物质积累及N、P、K吸收、积累、运转的影响。结果表明：覆膜＋遮阳处理相比露地播种处理单株干物质积累量提高16.6%~26.5%。覆膜＋遮阳处理增加了苗期和成熟期植株N、P、K含量,促进N、P、K吸收,显著提高全生育期N、P、K积累量,提高幅度分别为14.1%~33.3%、18.6%~34.8%、14.8%~71.5%;对营养体N、P分配系数影响较小,但提高了营养体K分配系数,而降低了生殖体K分配系数。与露地播种相比,覆膜＋遮阳处理降低了茎叶中N和P向荚果中的运转量、运转率,但提高了茎叶K向荚果中的运转量和贡献...

Taking Xianghua 2008 as material,the experiment was carried out at Yunyuan Base of Hunan Agricultural University.The treatment of mulching plastic film and shading was adopted to study its effects on the accumulation of dry matter and the absorption,accumulation and transportation of nitrogen,phosphorus and potassium during seedling stage to mature stage compared with open field cultivation.The results showed that the dry matter accumulation per single plant of film mulching and shading treatment increased by 16.6%～26.5%.The film mulching and ...
