摘要
为推广种植再生稻提供科学依据,在湖北省荆门市黄棕壤性水稻土上设置了3种不同用肥量和用种量耦合模式,展开了用种量和用肥量对‘新两优233’再生稻产量和养分吸收的影响研究。结果表明:两季均以Z1F2用肥量产量最高,分别为17.83 kg/plot和11.36 kg/plot,用肥量比用种量对产量的影响更大,中用肥量(F2)的产量效益较佳;用种量和用肥量共同调节再生稻植株对N、P、K养分的吸收,对N素、P素的吸收总为相互促进作用,对K素的吸收与N素、P素存在相互拮抗作用。综合用种量和用肥量对两季产量和养分吸收的影响,在黄棕壤性水稻土上种植‘新两优233’再生稻推荐的最佳肥种耦合模式为ZIF2模式。
Aiming at developing ratooning rice in China, three coupled modes with different fertilizer amountand seed sowing quantity were set up on the yellow-brown soil in Jingmen City, Hubei Province. The effects ofseed sowing quantity and fertilizer amount on the yield and nutrient uptake of‘Xinliangyou 233＇were studied.The results showed that, Z1 F2 model obtained the highest yield in both the main crop season and ratoon cropseason, which was 17.83 kg/plot and 11.36 kg/plot, respectively. The fertilizer amount had much more influenceon yield than that of seed sowing quantity, and the medium amount of fertilizer（F2） got better yield and benefit.Both fertilizer amount and seed sowing quantity adjusted the uptake of N, P and K in ratooning rice together.The uptake of N, P element had a mutual promotion effect, but the uptake of K and N, P element had anantagonistic effect. According to the effect of fertilizer amount and seed sowing quantity on the yield andnutrient uptake of‘Xinliangyou 233＇ratooning rice, the recommended coupled mode is Z1 F2 for cultivation inthe yellow-brown soil.
