摘要
田间试验结果表明，有机无机肥配合施用是提高水稻产量和施肥效益的有效措施。与单施化肥相比，有机无机肥配施提高了水稻分蘖成穗率，促进成熟期光合同化产物向穗部运转，谷草比、结实率、千粒重提高。此外，配施对稻田土壤供肥能力、酶活性的提高以及土壤物理性状的改善亦有明显的促进作用。
Results of location field experiment showed that combined organic manure and chemical fertilizer was an effective fertilization for improving both rice grain yield and fertilizer efficiency Compared with pure chemical fertilizer dressing,combined organic manure and chemical fertilizer dressing increasing ear/tillering ratio, improving photosynthetic metabolites transtration to ear, percentage of full grains and weight of thound grains In addition, combined organic manure and chemical fertilizer dressing had positive effects on improving soil fertility, enzymatic activity and physical characters
