摘要
对自行研制的5种控释肥料进行田间试验,研究控释肥料对大白菜的产量、品质以及养分利用率的影响。结果表明,在等N、P、K比例和等养分量处理下,控释肥料可以显著提高大白菜产量和提高养分利用率。与普通肥料1次性施用相比,控释肥料处理增加产量5.8%～16.9%,氮、磷、钾当季利用率分别提高3.2～13.6,3.2～10.3和9.2～19.4个百分点;与普通肥料分2次施用相比,控释肥料处理增产3.8%～14.7%,氮、磷、钾当季利用率分别提高了1.8～10.4,1.5～7.1和-1.0～9.2个百分点。此外,控释肥料对大白菜的品质也有一定影响。
A field experiment was conducted to study the effect of 5 new controlled release fertilizers on the yield and quality of Chinese cabbage and nutrient use efficiency. The result showed that the controlled release fertilizers could increased Chinese cabbage yield and improved nutrient use efficiency significantly compared to common straight fertilizers at same N, P, K proportion and rate. Comparing to single applying common fertilizers, the controlled release fertilizers increased Chinese cabbage yield by 5.8%-16.9%; improved nitrogen, phosphorus and potassium use efficiency by 3.2%- 13.6%, 3.2%-10.3% and 9.2%-19.4% respectively. Comparing split applying common fertilizers （2 times）, it increased the yield by 3.8%-14.7%; the nutrients use efficiency increased by 1.8%-10.4%, 1.5%-7.1% and -1.0%-9.2% respectively. In addition, the controlled release fertilizers also showed a beneficial result on the Chinese cabbage quality.
