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。
The effects of three fertilization methods and three different planting density on the yield and composition factors and the quality of rice under the methods of throwing seedlings were studied. The results showed that: the fertilization mode had significant and extremely significant effects on the plant height and stalk weight; the planting density had a significant effect on plant height; the interaction effect of fertilization mode and planting density had a significant effect on the rate of milled rice; the yield was not significantly correlated with other traits ; Effective panicle number and spikelets per panicle were extremely significant negative correlation. The results of comprehensive analysis showed that high density planting and re-applying of medium-term fertilizer was the best method of seedling throwing cultivation.
