在赤壁市双季稻区研究了不同的土壤培肥措施对土壤理化性质及双季稻产量及产量组成的影响。结果表明,与单施化肥的处理相比,添加有机物料增加了土壤有机质、全氮、碱解氮、有效磷与速效钾含量;添加有机物料的土壤培肥处理的稻谷产量都有所增加,早稻产量增加最高达833.40 kg/hm~2,增产15.55%,最低增加475.05 kg/hm~2,增产8.87%;晚稻产量增加最高达733.35 kg/hm~2,增产10.72%,最低增加375.00 kg/hm~2,增产5.48%。化肥配合畜禽粪便处理显著增加了稻谷的有效穗与穗粒数,提高了水稻子粒与秸秆中的N、P、K养分含量。
The effects of different soil fertility management practices on soil physical and chemical properties and double-cropping rice yield and yield components were studied in double cropping rice in Chibi. The results showed that compared with the single application of chemical fertilizers, the addition of organic materials increased the content of soil organic matter, total nitrogen, available nitrogen, available phosphorus and available potassium; the yield of paddy with organic fertilizers increased, The yield of early rice increased up to 833.40 kg / hm ~ 2, increased 15.55%, the lowest increased 475.05 kg / hm ~ 2, increased yield 8.87%; late rice increased up to 733.35 kg / hm ~ 2, increased 10.72% hm ~ 2, yield 5.48%. Fertilizer combined with livestock manure treatment significantly increased the effective spikes and grains per spike, and increased N, P and K contents in rice grains and straw.
