- 摘要:
- 为促进东北地区水稻优质高效生产,本研究在水稻常规种植模式下,以氨基酸水溶肥为试验材料,将苗床喷施氨基酸水溶肥作为水稻返青肥进行试验,试验设4个处理、7个试验点次,调查其对水稻返青天数、秧苗素质及产量的影响。结果表明,秧苗移栽前2~3 d喷施11.0 L·(667 m2)-1氨基酸水溶肥,平均返青天数6.9 d,较CK提前3.1 d;移栽后15 d株高较CK提高13.9%、根长较CK提高15.2%、株鲜重较CK提高161%、根鲜重较CK提高19.7%、叶绿素较CK提高21.2%、氮含量较CK提高15.5%;产量较对照提高63%,净增经济效益较CK提高89.62元·(667 m2)-1。同时氨基酸水溶肥+微生物菌剂和常规施肥试验处理的各指标较CK处理均有所提高,但整体低于氨基酸水溶肥处理。说明氨基酸水溶肥会使水稻返青天数减少、促进水稻生长,增加产量和经济效益。
- Abstract:
- In order to promote the high quality and efficient production of rice in the Northeast region, this study used amino acid water-soluble fertilizer as the experimental material under the conventional planting mode of rice. The experiment was conducted by spraying amino acid water-soluble fertilizer on the seedling bed as the rice rejuvenation fertilizer. Four treatments and seven experimental points were set up to investigate their effects on the days of rice rejuvenation, seedling quality, and yield. The results showed that spraying 11.0 L·(667 m2)-1 of basic amino acid water-soluble fertilizer 2-3 days before transplanting resulted in an average of 6.9 days of rejuvenation, 31 days earlier than CK; 15 days after transplantation, the plant height increased by 13.9% compared to CK, the root length increased by 15.2% compared to CK, the fresh weight of the plant increased by 16.1% compared to CK, the fresh weight of the root increased by 19.7% compared to CK, the chlorophyll increased by 21.2% compared to CK, and the nitrogen content increased by 15.5% compared to CK; The yield increased by 6.3% compared to CK, and the net economic benefit increased by 89.62 yuan·(667 m2)-1compared to CK. At the same time, the data of amino acid water-soluble fertilizer+microbial inoculants and conventional fertilization treatment were improved compared to CK treatment, but the overall experimental data was weaker than that of amino acid water-soluble fertilizer treatment. Amino acid water-soluble fertilizer can reduce the number of days for rice to turn green, promote rice growth, and increase yield and economic benefits.
