当前,在大豆高产栽培中,施肥多属经验施肥,较为进展一步也不过是测土施肥。经验施肥,时常出现施肥过多而浪费,或起副作用;过少致使养分不足而减产。测土施肥虽较科学,但就目前化验设备、条件和水平,还不能广泛及时的为施肥提供依据,严重者违误农时。据此,研制标准施肥运算式,对大豆高产栽培制定有效施肥措施,促进大豆高产,提高经济效益有积极作用。依据运算式,可按照各自生产条件,计算选用,达到施肥标准化、公式化和科学化。
Currently, high-yielding soybean cultivation, fertilization are mostly experienced fertilization, more progress is nothing but soil testing and fertilization. Experience in fertilization, fertilizers often appear too much and waste, or play a side effect; too little to make the lack of nutrients and cut. Soil testing and fertilization is more scientific, but the current laboratory equipment, conditions and levels, can not provide a timely and extensive basis for the fertilization, serious cases of violation of agricultural time. Accordingly, the development of standard fertilization formula, high-yield cultivation of soybean formulated effective measures to promote high-yield soybean and improve economic efficiency have a positive effect. According to the formula, according to their respective production conditions, calculate the selection, to fertilization standardization, formulation and scientific.
