丰华占优质高产高效抛秧栽培技术研究

研究了丰华占在抛秧栽培方式下,3种施肥方式和3种不同抛植密度对产量及构成因子、稻米品质的影响。结果表明:施肥方式对株高和秆重有显著和极显著影响;种植密度对株高有显著影响;施肥方式和种植密度互作效应对整精米率有显著影响;产量与其他性状相关不显著;有效穗数与每穗实粒数呈极显著负相关。综合分析结果表明,高密度抛植并重施中期肥是丰华占最优的抛秧栽培方式。

Study on cultivation technique of Fenghuazhan for good quality,high yield and high efficiency

Various effects,of 3 planting densities and 3 patterns of fertilizer application,on yield and quality of Fenghuazhan were studied.The results showed that effects on plant height and stem weight caused by patterns of fertilization were significant and highly significant,respectively,and effect on plant height caused by planting density was significant,and interaction effect on head rice caused by patterns of fertilizer application and planting density was significant.Correlation analysis showed that yield wasn't correlated to other traits significantly,and productive panicle was negatively correlated to filled grains.Integrative result showed best cultivation of Fenghuazha was cast-transplanted with high planting density and more feritiliztion in middle duration.
