为探明糯小麦‘1718WX’在重庆地区的高产栽培技术,采用三因素裂-裂区试验,研究不同播期、施肥量和种植密度对糯小麦产量和品质的影响.结果表明,产量随着播期的推迟呈先增加后下降的趋势,随施肥量、种植密度的增加先增加后下降,播期、施肥量和种植密度对产量的影响均达到极显著水平.播期对株高、单穗粒数和有效穗数的影响达到极显著,对千粒质量影响达到显著;施肥量对单穗粒数影响不显著,对其他主要农艺性状的影响达到显著或极显著;种植密度对千粒质量和有效穗数影响达到显著,对株高和单穗粒数影响不显著.品质性状方面,蛋白质和面筋含量随着播期的推迟而增加,随着施肥量的增加而增加,种植密度对品质性状无显著影响.在本试验条件下,A2B2C2处理组合符合糯小麦高产优质栽培措施,即以播期11月5日,施肥量300kg/hm2,种植密度1.80×106苗/hm2为宜.
In order to investigate the high-yielding cultivation techniques of waxy wheat ’1718WX’ in Chongqing, the effects of different sowing dates, fertilizer amount and planting density on the yield and quality of waxy wheat were studied by the three-factor fissure-rift zone test. The results showed that with the The sowing date postponed first and then decreased, with the amount of fertilizer, planting density increased first and then decreased, sowing date, the amount of fertilizer and planting density on the yield were significantly affected the sowing date of plant height, single The number of spikes per panicle and the number of effective panicles reached extremely significant, which had a significant impact on the quality of 1000 grain; the effect of fertilization on the number of grains per spike was insignificant, and the other agronomic traits had significant or extremely significant effects; The effects of quality and effective panicle number were significant, and had no significant effect on plant height and grain number per spike. In terms of quality traits, protein and gluten content increased with the delay of sowing date, increased with the increase of fertilizer amount, Under the experimental conditions, the combination of A2B2C2 was in line with the high-yielding and high-quality cultivation of waxy wheat, that is, sowing date of November 5, the amount of fertilizer 300kg / hm2, planting density 1.80 × 106 / hm2 is appropriate.
