袋控肥对吐鲁番无核白葡萄产量品质的影响

解决新疆砂石化土壤漏肥严重的问题,力求在吐鲁番无核白葡萄生产上做到节约肥料、节省人工成本及环保;验证袋装缓控释肥在吐鲁番无核白葡萄生产上的效果.以常规施肥方法为对照,通过大田试验研究带孔的牛皮纸袋装肥料对葡萄产量和品质,及光合作用、养分吸收和干物质累积等的影响.与当地常规施肥方式相比,牛皮纸袋包装施肥方式增产17.4 %,达到5 991.0 kg/hm2;光糖度提高了17.9%,达到了19.13 g/L;叶片光合速率、叶绿素含量、N、P、K含量等均有提高.袋控肥在吐鲁番无核白葡萄生产上有较好的缓释效果,保肥能力强,可以作为当地无核白葡萄生产的有效缓控释肥措施.

Effect of Paper Package Fertilization on Yield and Quality of 'Thompson Seedless' Grape in the Turpon Region

Settlement of Xinjiang gravel soil fertilizer leakage problem, sought to achieve savings of fertilizer production, save labor costs on thompson seedless grapes in Turpan; verify the results of sustained and controlled release fertilizer in bags on thompson seedless grapes production in Turpan. Conventional methods of fertilization as the control, through the study of field experiments of kraft paper bags with holes fertilizers of grape yield and quality, and photosynthesis, nutrient uptake and dry matter accumulation and so on. Compared with conventional methods fertilization, kraft paper bags fertilization increased 17. 4 percent,5 991. 0 kg/hm~2; light sugar increased 17. 9 percent, reaching a 19. 13 g/L; the leaf photosynthetic rate, chlorophyll content, N, P, K content have improved. Bags of fertilizer has a good sustained-release effect on thompson seedless grapes production in Turpan. The protection of fertilizer was strong,it's a effective measures to alleviate the controlled-release fertilizer on local thompson seedless grapes productiong.
