摘要
为了明确水稻秧池培肥技术对苏北地区机插秧秧苗素质及产量的影响,以便为苏北地区水稻机插秧技术推广应用提供参考,通过大田随机区组试验,设置不施肥(CK)、复合肥+尿素(CF+N)、二铵+尿素(TF+N)、复合肥+尿素+有机肥(CF+N+O)、二铵+尿素+有机肥(TF+N+O)5个处理,研究水稻秧池有机肥培肥对苏北地区机插秧秧苗素质及产量的影响。结果表明,与CK相比,TF+N处理的株高、叶长、叶宽、茎基宽、叶龄分别显著增加13.52%、20.14%、10.19%、9.09%、5.00%;CF+N+O处理的株高、叶长、茎基宽、叶龄分别显著增加7.29%、10.72%、13.64%、2.50%;TF+N+O处理的株高、叶长、叶宽、茎基宽分别显著增加11.21%、13.07%、9.38%、13.64%。在产量方面,与CK相比,TF+N处理的穗数、穗粒数、理论产量和实际产量分别显著增加4.56%、8.91%、14.13%、11.60%,CF+N+O处理的实际产量显著增加9.63%。综上所述,在本试验条件下,短期内有机肥培肥秧池效果不显著;二铵配施尿素培肥秧池效果最好,水稻产量最高。
The purpose of this study was to determine the effects of rice seedling pond fertilization technology on the quality and yield of rice seedlings cultivated for mechanical transplanting in northern Jiangsu Province.A randomized block field trial was carried out in northern Jiangsu Province to investigate the effects of an organic fertilizer on seedling quality and yield in a rice seedling pond,which involved five treatments as follows:no fertilization(CK),a compound fertilizer combined with urea(CF+N),phosphorous diamine fertilizer combined with urea(TF+N),a compound fertilizer combined with urea and an organic fertilizer(CF+N+O),phosphorous diamine fertilizer combined with urea and an organic fertilizer(TF+N+O).The results showed that the treatment TF+N significantly increased plant height,leaf length,leaf width,leaf base width,and leaf age by 13.52%,20.14%,10.19%,9.09%,5.00%,respectively,as compared with CK;the treatment CF+N+O significantly increased plant height,leaf length,leaf base width,and leaf age by 7.29%,10.72%,13.64%,and 2.50%,respectively,in comparison with CK;the treatment TF+N+O significantly increased plant height,leaf length,leaf width,and leaf base width by 11.21%,13.07%,9.38%,and 13.64%,respectively.In terms of yield,compared with CK,the treatment TF+N significantly elevated panicle number,grain number per panicle,theoretical yield,and actual yield by 4.56%,8.91%,14.13%and 11.60%,respectively.The actual yield of the treatment CF+N+O rose significantly by 9.63%.In summary,under the conditions in this trial,the effect of the organic fertilizer on seedling cultivation was not significant in a short term,while application of phosphorous diamine fertilizer combined with urea to the seedling pond had the best effect and attained the highest yield of rice.This study provides a reference for promotion and application of rice seedling transplanting technology in northern Jiangsu.
