功能肥对不同播期直播水稻产量的影响
Effect of Functional Fertilizer on Yield of Direct-seeded Rice with Different Sowing Dates
摘要
Abstract
In order to study the effect of functional fertilizers on the yield of direct-seeded rice at different sowing dates,explore the best yield increasing effect of functional fertilizers at different sowing dates,screen the most suitable sowing date and functional fertilizer combination,and use C Liangyou 919 and Chuanzuo 6 You 178 as experimental materials.Three sowing dates were set,namely B1(May 16),B2(May 23),and B3(May 30),and the four functional fertilizers were represented by T1,T2,T3,and T4,respectively.Spraying water was used as a control for the experiment.The results showed that the full growth period of the two rice varieties shortened with the delay of sowing date.Different functional fertilizers had an impact on the yield and effective number of panicles of C Liangyou 919 at different sowing dates.The number of grains per spike,thousand grain weight,and seed setting rate had a significant impact;there was a significant impact on the yield,effective number of spikes,and number of grains per spike of Chuanzuo 6 You 178,while there was no significant impact on thousand grain weight and seed setting rate.The yield increase effect of C Liangyou 919 was most significant under the combination of sowing date B2 and functional fertilizer T3,with the highest yield reaching 12.09 t/hm2;Under the combination of sowing date B3 and functional fertilizer T3,the yield of Chuanzuo 6 You178 increased significantly,reaching the highest yield of 12.59 t/hm2.In summary,T3 functional fertilizer has a sig-nificant yield increasing effect on both varieties,because T3 treatment mainly increases the number of grains per panicle in hybrid rice,indica-ting that functional fertilizer is beneficial for rice yield increase.关键词
