施肥量和施肥方法对机穴播“秀水134”产量的影响

Effects of Different Fertilizing Amount and Fertilizing Methods on the Yield of “Xiushui 134” in Mechanical Hole Sowing

为探索金山区"秀水134"水稻机穴播技术,先后进行了不同施肥量、不同施肥方法对"秀水134"产量影响的研究。结果表明,随着施肥总氮量的增加,有效穗和实际产量呈先增加后减少的趋势,在总氮量为300 kg/hm^2时产量最高,为9 715.5 kg/hm^2;在施肥总氮量为300 kg/hm^2情况下,随着基蘖肥和穗肥比例的提高,有效穗和实际产量呈先增加后减少的趋势,基蘖肥和穗肥比例为7∶3时产量最高,为10 174.5 kg/hm^2。

In order to explore the mechanical hole sowing technology of the rice variety “Xiushui 134” in Jinshan District,the effects of different fertilization amount and fertilization methods on the yield of “Xiushui 134” were studied.The results showed that with the increasing of the total nitrogen fertilizer,the effective ears and the actual yield showed a trend of first increasing and then decreasing.When the total nitrogen amount was 300 kg/hm 2,the yield was the highest,which was 9 715.5 kg/hm^ 2.In the case of 300 kg/hm^2 total nitrogen fertilizer,as the ratio of the basal and tillering fertilizer and the panicle fertilizer went up,effective ears and the actual yield showed a trend of first increasing and then decreasing.When the ratio of the basal and tillering fertilizer and the panicle fertilizer was 7 ∶3,the yield was the highest,which was 10 174.5 kg/hm^ 2.
