大量的试验表明,有机肥料对获得作物的优质高产是不能为化肥所替代的,二者成互补的关系。目前我国农村有机肥料的投入仍以家畜粪为主,因此阐明这些有机肥施入土壤后的氮素矿化特征,在农业生产上具有重要意义。本试验采用盆栽试验的方法详细研究了几种有机肥氮素在淹水条件下的矿化特征及其对水稻生长发育的影响,为有机无机肥料的配合施用提供理论依据。 A large number of experiments show that organic fertilizers can not be replaced by chemical fertilizers to obtain high quality and high yield of crops, and the two are complementary to each other. At present, the input of organic fertilizers in rural areas in our country is still dominated by livestock manure. Therefore, elucidating the characteristics of nitrogen mineralization after these organic fertilizers are applied to soil is of great significance in agricultural production. In this study, pot experiments were conducted to study in detail the mineralization characteristics of several organic nitrogen fertilizers under flooding conditions and their effects on the growth and development of rice so as to provide a theoretical basis for the combination and application of organic and inorganic fertilizers.
