The Effect Of Two Kinds Of Liquid Fertilizer With Compound Fertilizer On The Chinese Cabbage

Because producers want to get high output and high benefit excessive fertilizers were employed, resulting in serious decline of vegetable quality, high nitrate accumulation, environment deterioration, which led to fertility waste,finally jeopardized human’s survival and health. In order to improve the quality of Chinese cabbage, will change the traditional way of fertilizer application. Chinese cabbage, a very important vegetable, is severely affected. In this experiment, mixed liquid fertilizer and Solid fertilizer were used to study liquid fertilizer application on yield, nitrate in the soil, fertilizer utilization influence of a fertilizer in different soil layers, rate of the quarter. In order to search for reliable measures to control nitrate accumulation and improve the quality of vegetableand provide the feasible for the safe production of vegetables1. During in Chinese cabbage cultivation time,the quality of Chinese cabbage showed a trend of rise before they are stable. During the whole growth period, two faste period of dry matter accumulation exist, including the resettling stage and the package heart stage, The dry matter of cabbage first increase and then decrease throughout the experiment and he quality of Chinese cabbage showed the same result.2. Active cell biological fertilizer and humic acid fertilizer application can improve the quality of Chinese cabbage and reduce the nitrate content in Chinese cabbage.3. As cells fertilizer and humic acid fertilizer application rate increased of the quality of Chinese cabbage, but the decline in output.4. In the fertilizer application of ordinary fertilizer: cells fertilizer : humic acid fertilizer=2:1:1,the results of eight treatments showed that Chinese cabbage has the highest yield and Comprehensive,high utilization of NPK in season.5. Applying liquid fertilizer can significantly reduce the 0~ 60 cm soil alkaline hydrolysis nitrogen obviously, available phosphorus and available potassium content. With the increase of the proportion of liquid fertilizer applied, the higher the residual amount. Throughout the residues in the soil layer, all kinds of fertilizer will be accumulated in 0 ~ 20 cm arable layer soil.
