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。

Abstract: Aiming at providing the basis for the development of ratooning rice of our country, the effect of different number of seeds and different amount of fertilizer on the yield and nutrient uptake of plant about ‘Xinliangyou 233’ratooning rice cultivated on the yellow-brown soil in Hubei province were explored. The results were as follows: In both the main crop season and ratoon crop season, the yield of the Z1F2 model was the highest, which was 17.83 kg/plot and 11.36kg/plot, respectively. The amount of fertilizer had much more influence than the number of seeds and the medium-use (F2) fertilizer was the best. Both the amount of fertilizer and number of seeds affected the nutrient uptake of the plant, in a word , the absorption of N, P element had a mutual promotion effect but the absorption of K and N, P element had an opposite effect. According to the effect of different number of seeds and different amount of fertilizer on the yield and nutrient uptake of plant about‘Xinliangyou 233’ratooning rice, the recommended model is the Z1F2 model when cultivated on the yellow-brown soil.
