研究了在插秧移栽条件下,三种施肥方式和三种不同移栽密度对丰华占的产量及构成因子、品质及理化指标的影响。方差分析结果表明:施肥方式对理论产量和直链淀粉的影响分别达到显著和极显著水平,种植密度对有效穗数、理论产量和食味品质的影响分别达极显著、显著和显著水平。相关分析结果表明:折实际产量分别与理论产量、有效穗数呈极显著和显著相关。综合试验结果,高密度(插植规格20 cm×20 cm)、施用控释肥是丰华占最优的插秧方式。
The effects of three fertilization methods and three different transplanting densities on the yield, composition, quality and physico-chemical indices of Fenghua Zhan were studied under transplanting of transplanting seedlings. Analysis of variance showed that the effects of fertilization on theoretical yield and amylose reached significant and extremely significant levels respectively. The effects of planting density on effective panicle number, theoretical yield and taste quality were significant, significant and significant respectively. The result of correlation analysis shows that the actual yield of fold is significantly and significantly related to the theoretical yield and effective panicle number respectively. According to the comprehensive test results, high density (planting size of 20 cm × 20 cm) and application of controlled release fertilizer are the best transplanting methods for Fenghua.
