“美洲星”液肥含有大豆生长所必需的氮、磷、钾、钙、镁、硫、铁、锌、铜、锰、钼、硼等多种营养元素以及可提高作物抗旱、防病能力的黄腐酸钠,在大豆上使用具有平衡养分,促进生长,增强抗逆性及增产增收等功效。尤其对大豆的早衰具有明显的防治效果。 具体使用方法如下: 1.土壤处理 在大豆播种后即刻用美洲星液肥每亩100~150毫升对水50~75千克喷于土壤。在覆土前喷施,播后覆土效果更好。同时,可降低30%~50%的氮、钾肥和15%~30%的磷肥的施用量以及10%的播种量。可使大豆根多而壮,叶片厚,枝茂,增加产量10%左右。
“American Star” liquid fertilizer contains a variety of nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, zinc, copper, manganese, molybdenum, boron and other nutrients necessary for the growth of soybeans and yellow Sodium fulvic acid, used in soybeans have the balance of nutrients, promote growth, enhance resistance and increase yield and other effects. Especially for soybean premature aging has obvious control effect. Specific use is as follows: 1. Soil treatment immediately after sowing with soybean American Star liquid per acre 100 to 150 ml of water spray 50 to 75 kg on the soil. Sprayed before the cover soil, sowing soil cover better. At the same time, it can reduce 30% ~ 50% of nitrogen, potassium and 15% ~ 30% of the application of phosphate fertilizer and 10% of seeding. Soybean can make more and more strong, thick leaves, Zhimao, increase production about 10%.
