| 摘 要： | 采用田间小区试验,以普通单质肥和＂洋丰＂牌高浓度复合肥为对照,研究了＂湘珠＂牌水稻专用配方肥在湖南省8种不同类型水稻土条件下早稻上的施用效果。结果表明,在供试水稻土条件下,＂湘珠＂牌水稻专用肥对早稻的生长发育与养分吸收、经济性状的改善以及产量的提高都有明显的效果。在施用等养分量条件下,＂湘珠＂牌水稻专用肥比单质肥平均增产7.96%,比洋丰牌复合肥平均增产5.05%,比不施肥处理平均增产75.5%。＂湘珠＂牌水稻专用肥主要增加了有效穗数和穗长,提高了结实率和千粒重,减少了水稻的空瘪粒。＂湘珠＂牌水稻专用肥处理的土壤养分有效性高,有利于水稻对土壤养分的吸收,收获后土壤速效氮、钾养分含量均低于其他处理。不同土壤条件下水稻对肥料氮、钾养分的当季利用率为＂湘珠＂牌水稻专用肥〉洋丰牌复合肥〉单质肥料,对肥料磷的利用率为洋丰牌复合肥〉＂湘珠＂牌水稻专用肥〉单质肥料。

| Abstract: | Field plot experiments were conducted in eight types of paddy soils to study the effects of Xiangzhu rice-specific formula fertilizer on early rice with single-element fertilizers and Yangfeng compound fertilizer with higher nutrient concentration as controls.The results showed that Xiangzhu specific formula fertilizer had better effects in improving growth and development,nutrition uptake,economic characters and increasing yield of early rice under the conditions of the tested paddy soils.Under the same fe... |
