| 摘 要： | 以优质水稻品种盐丰47为供试材料进行田间试验,采用小区对比方法,设施肥量(7个)和移栽基本苗两因素,共14个处理,研究了硅钙肥和液态硅两种硅肥与基本苗配置对水稻生长发育、产量及品质的影响。结果表明,施用两种硅肥都能使水稻分蘖数增加,提高成穗率,增加产量,增强抗倒伏及抗病能力,改善稻米品质,使稻米的垩白度、垩白粒率降低的同时,提高稻米的糙米率、精米率、整精率。其中在基本苗64.5×10~4株/hm~2中,C5-1喷施处理(基本苗64.5万株/hm~2条件下,拔节期、抽穗期各喷施450 mL/hm~2)产量最高,为10 893.0 kg/hm~2。

| Abstract: | The field experiments were conducted with Yanfeng47,a high-quality ricevariety,as the test material. Theeffects of silicon-calcium fertilizer and liquid silicon fertilizer on ricegrowth,yield and quality were studied by comparingplots,facility fertilizer(7)and transplanting basic seedlings with 14 treatments. The results showed that both siliconfertilizers could increase tiller number,panicle yield,yield,lodging resistance and disease resistance,improve ricequality,reduce chalkiness and chalky grainrate,and improve brown ricerate,milled rice rate and finishing rate. Among the 64.5×104seedlings per hectare of the basicseedlings,the highest yield of C5-1 was 10 893.0 kg/hm2. |
