辽宁黄海稻区水稻应用缓控释肥料肥效试验研究

Experimental Study on the Effect of Slow and Controlled Release Fertilizer on Rice in Huanghai Rice Area of Liaoning Province

连续2 a以丹粳17号为试验材料,采用高塔复合肥(FL1)、佳裕脲甲醛工艺含铵态氮脲醛缓释肥料(FL2)、锌碳双络控包膜类缓释肥料(FL3)、亚美特碳酸核芯含植本生命素碳基肥料(FL4)和嘉年水稻专用复合肥(CK),共5种新型肥料,设置5个处理,3次重复。结果表明,FL3和FL4的稻瘟病发病率分别比对照降低36%和31.6%(由于气候原因,2019年~2020年黄海稻区稻瘟病发病率普遍较高),千粒重分别比对照提高3.2%和4.9%,结实率分别比对照提高3.4%和7.1%,水稻产量分别比对照提高5.6%和6.1%,表现突出。

Taking Dangeng-17 as the test material for two consecutive years,five new fertilizers including Gaota compound fertilizer(FL1),Jiayu formaldehyde process urea formaldehyde slow-release fertilizer containing ammonium(FL2),zinc-carbon double envelope controlled slow-release fertilizer(FL3),Yameite carbonic acid core carbon-based fertilizer containing phytobiotin(FL4),and Jianian rice special compound fertilizer(CK)were used,and five treatments were set,three repetitions.The results showed that the incidence of rice blast in FL3 and FL4 was 36%and 31.6%lower than that in the control,respectively(due to climate reasons,the incidence of rice blast in Yellow Sea rice area from 2019 to 2020 was generally high),the 1000-grain weight was 3.2%and 4.9%higher than that in the control,and the seed setting rate was 3.4%and7.1%higher than that in the control,respectively.The yield of rice was increased by 5.6%and 6.1%,respectively.
