浮梁县是赣东北山区县,水田面积26.8万亩,早稻面积8万亩,农民早稻盲目施肥现象比较普遍。为探索浮梁县早稻的最佳施肥量、施肥比例、施肥时间、施肥方法,为全县早稻配方施肥提供依据,2013年开展了早稻“3414”肥效试验。1材料与方法 1.1试验材料试验设在浮梁县庄湾乡仓下村龙船湾畈农户汤金河责任田中,土壤为中潴灰麻沙泥田,肥力中上。试验田土样分析结果:碱解氮203mg/kg,有效磷11.6 mg/kg,速效钾85 mg/kg,有机质29.3 g/kg,pH 5.1。供试肥料为尿素(N 46%)、钙镁磷肥(P2O512%)、氯化钾(K2O 60%)。供试早稻品种为株两优02。
Fuliang County is the northeastern Jiangxi mountainous counties, paddy field area of 268000 acres, 80000 acres of early rice area, blind rice farmers more common phenomenon. In order to explore the best fertilization rate, fertilization ratio, fertilization time and fertilization method of early rice in Fuliang county, this study provided the basis for the formula fertilization of early rice in the county. In 2013, the experiment of early rice “3414” was carried out. 1 Materials and Methods 1.1 Test Materials The experiment was conducted in Tianzhong, a farmer’s household, in Longxia Wan, Kuang Xia Village, Zhuangwan Village, Zhuangwan Township, Fuliang County. Soil samples from the experimental field were analyzed. The contents of available nitrogen (203 mg / kg), available phosphorus (P) 11.6 mg / kg, available potassium 85 mg / kg, organic matter 29.3 g / kg and pH 5.1. The tested fertilizers were urea (N 46%), calcium magnesium phosphate (P2O512%) and potassium chloride (K2O 60%). The test for early rice varieties Liangyou 02.
