控释掺混肥在菠萝生产中的应用研究
|
摘要
传统的菠萝施肥技术重氮肥而轻磷肥和钾肥,导致果实发育不良,不仅影响产量和产品品质,而且肥料利用率很低。为了筛选适合菠萝生长的控释掺混肥配方及用量,开展了控释掺混肥在菠萝上应用的田间试验。试验结果表明,控释掺混肥能提高菠萝产量,增产幅度约5. 1%,氮素利用率可提高4. 3%～19. 2%。
The traditional pineapple fertilization technology pays attention to nitrogen fertilizer and ignores phosphate fertilizer and potash fertilizer,resulting in poor fruit development,which not only affects the yield and product quality,but also has low fertilizer utilization rate. In order to screen the formulation and application amount of controlled release bulk blended fertilizer suitable for pineapple growth,a field trial of controlled release bulk blended fertilizer applied to pineapple is carried out. Experimental results show that the controlled release bulk blended fertilizer can increase the yield of pineapple,the yield increase is about 5.1%,and the nitrogen utilization rate can be increased by 4.3% to 19.2%.
