Abstract: | The nitrogenous and phosphate fertilizers can obviously increase the yield of sea cabbages by 12.0%~35.8% for nitrogen,and by 5.30%~14.1% for phosphorus.Under different soil fertility levels,the highest quantity of nitrogenous fertilizer is 364.6,394.5 and 429.1 kg/hm2 respectively;the optimal nitrogenous fertilizer is 310.5,336.6 and 378.9 kg/hm2 respectively.The nitrogen use efficiency is 15%~20%,and the phosphorus use efficiency is 9.3%~11.0%. |
