应用标记15_M的田菁和硫铵进行一季水稻盆栽试验的结果表明,1.田菁和硫铵单独施用,田菁氨素的17.6％和41.8％分别为稻秆和谷粒利用,硫铵氨素的分别为15.1％和29.0％。这两种肥料氮在谷粒中分布的比例较大,稻杆和谷粒对田菁氨的利用率都高于硫铵氮.2.施用硫铵有促进水稻吸收土壤氨素的作用,比不施氨对照增加71.8％;相反,施用田菁减弱了水稻对土壤氨的吸收,比对照减少37.1％。3.田菁和硫铵混合施用,除了可使水稻对田菁氨的吸收增加(5.2％)。对硫铵氨的吸收减少(5.3％)外,亦有促进水稻增加吸收土壤氨素的作用,4.与硫铵单独施用的结果相比,这两种肥料混合施用,可以在消耗较少量土壤氨素的基础上,更好地维持水稻生长所需的氨营养供应。
The results of one-pot experiment on paddy with Jingtian and ammonium sulfate using the marker 15_M showed that: 1. Sesbania and ammonium sulfate were applied alone, and 17.6% and 41.8% of the cyanine were used as rice straw and grain, respectively. The primes were 15.1% and 29.0% respectively. The two kinds of fertilizer nitrogen in the distribution of grain in a larger proportion of rice straw and grain utilization of ammonia are higher than ammonium sulfate .2 ammonium sulfate can promote rice absorption of soil ammonia role than On the contrary, the application of Sesbana decreased the absorption of soil ammonia by rice, which was 37.1% less than the control. 3. Sesbania and ammonium sulfate mixed application, in addition to rice can increase the absorption of Sesbania ammonia (5.2%). Ammonia ammonium sulfate decreased (5.3%), but also to promote the rice to increase the absorption of soil ammonia factor, 4. Compared with the results of ammonium sulfate alone, the two kinds of fertilizer mixed application, consumption of less Soil ammonia based on the better supply of ammonia nutrients needed to sustain rice growth.
