Abstract
Low use efficiency of fertilizer is an important factor restricting yield increase of crop. In order to study new way to improve use efficiency of fertilizer, the impacts of water-soluble organic fertilizer combined with inorganic fertilizer form of spraying on the leaf and root on yield, quality and nutrient absorption of Chinese cabbage was investigated. The results showed that compared with the single application of inorganic fertilizer, water soluble organic fertilizer combined with inorganic fertilizer in the form of spraying on the leaf and root increased the production of Chinese cabbage by 7.3% and 18.8%,respectively. The package rate was increased by 7.2% and 4.7% respectively. Production effect of water soluble organic fertilizer was superior to spraying its on the leaf. Water soluble organic fertilizer combined with inorganic fertilizer in the form of spraying on the leaf and root reduced nitrate by 14.2% and 12.7% compared with the single application of inorganic fertilizer but not significantly increased VC. The fertilization of nitrogen, phosphorus and potassium increased by 12.1%, 6.4%, 3.4%and by 18.6%, 16.2%, 12.9%, respectively, compared with the single application of inorganic fertilizer in the condition of water soluble organic fertilizer combined with inorganic fertilizer in the form of spraying on the leaf and root. Water soluble organic fertilizer combined with inorganic fertilizer in the form of spraying on the leaf or root, the input and output ratio were 6.4, 16.6, respectively. The irrigation economic effect of water-soluble organic fertilizer was higher than that of spraying it on the leaf.
