以华南地区主栽水稻品种粤禾丝苗为材料,以不施肥为对照(CK),通过田间小区试验,研究了复合肥(T1)与海藻寡糖增效硅锌肥(AOS-SiZn)在分蘖期(T2)、孕穗期(T3)、分蘖期和孕穗期(T4)配施对水稻产量、品质和养分吸收的影响。结果表明:与CK处理和T1处理相比,复合肥与AOS-SiZn配施处理的水稻剑叶叶绿素相对含量、叶长、叶宽均有一定增加,可以提高水稻的有效穗数、结实率、千粒质量,不同处理的水稻产量表现为T4>T3>T2>T1>CK;复合肥与AOS-SiZn配施处理可以降低稻米垩白粒率和垩白度,提高稻米胶稠度,显著提高水稻对氮、磷、钾肥的利用率,具有增产提质的作用,其中以T4处理的效果较优。
Using the major rice cultivar Yuehe Simiao in South China as material, with no fertilization as the control (CK), a field plot experiment is established to investigate the effects of compound fertilizer (T1) combined with seaweed oligosaccharide-enhanced silicon-zinc fertilizer (AOS-SiZn) applied during the tillering stage (T2), booting stage (T3), and combined tillering and booting stages (T4) on rice yield, quality, and nutrient uptake. The results show that compared with CK and T1 treatments, combined application of compound fertilizer and AOS-SiZn increase chlorophyll relative content in flag leaves, leaf length, and leaf width, as well as improve effective panicle number, grain setting rate, and 1 000 grain weight. The yield performance among treatments follows the order: T4 > T3 > T2 > T1 > CK. The combined application of compound fertilizer and AOS-SiZn reduces chalky grain rate and chalkiness degree of rice, increases the gel consistency of rice, significantly improves nitrogen, phosphorus, and potassium fertilizer utilization rates and enhances both yield and quality, with the T4 treatment yielding the most favorable results.
