一、试验材料与方法1.试验设计处理1为新地牌植物氨基酸液肥。处理2为对照,当地常规叶面肥为磷酸二氢钾。采用小区对比试验,小区长10米,宽4.50米,面积为45米~2,6个小区随机排列,四周设保护行。2.试验地的基本情况试验地为砂壤土,土壤肥力中等,地势平坦。取土样于2003年秋收后进行,采样深度0～20厘米,碱解氮45.36毫克/千克,速效磷12.87毫克/千克,速效钾189.10毫克/千克,有机质13.22克/千克。二、试验过程1.施肥基肥和追肥为当地常规施肥,即基肥667米~2施尿素20千克、磷酸二铵30千克,追肥为尿素20千克分3次于前3水追施。叶面喷施肥料为:处理1叶面喷施3次,于苗期(6月3日)、现蕾期(6月21
First, the test materials and methods 1. Experimental design and processing 1 for the new brand of plant amino acid liquid fertilizer. Treatment 2 as a control, the local conventional foliar potassium dihydrogen phosphate. Community comparison test, a small cell length of 10 meters, 4.50 meters wide, an area of 45 meters to 2,6 cells randomly arranged around the protection line. 2. The basic situation of the experimental site for the test of sandy loam soil fertility medium, flat. The soil samples were collected in the autumn of 2003 and collected at depths of 0-20 cm, 45.36 mg / kg of available nitrogen, 12.87 mg / kg of available phosphorus, 189.10 mg / kg of available potassium and 13.22 g / kg of organic matter. Second, the test process 1. Fertilization basal fertilizer and dressing for the local conventional fertilization, that is, basal 667 m ~ 2 20 kg of urea, 30 kg of diammonium phosphate, topdressing urea 20 kg 3 times in the top 3 water chase. Foliar application of fertilizer as: treatment 1 foliar spray 3 times, at the seedling stage (June 3), budding period (June 21
