以中嘉早17、中早39、泰优390和汕优46为材料,研究了欣庆凹凸棒复合微生物肥以及与调节剂的配合施用对水稻的生长发育、产量以及水稻重金属镉含量的影响。结果表明,与对照T1相比,施用欣庆凹凸棒复合微生物肥和调节剂处理（T2、T3、T4、T5）可以显著提高水稻产量,有利于获得较多的穗数和每穗粒数,早稻和晚稻最高产量分别为6.39 t/hm^2、7.88 t/hm^2;可显著降低稻草和糙米中镉含量,分别比对照低1.16%-53.16%、0.64%-44.83%。在250kg/hm^2凹凸棒复合微生物肥施用量下,不同调节剂用量（0-300 kg/hm^2）处理下水稻产量、结实率差异不明显,但泰优390、中早39的穗粒数有显著差异,4个品种只有泰优390的千...

In order to study the effects of Xinqing attapulgite composite microbial fertilizer and conditioning agent on the growth of rice and the content of cadmium in rice,a field experiment was conducted in 2016,4 rice varieties of Zhongjiazao 17,Zhongzao 39,Taiyou 390 and Shanyou 46 selected as test materials. The results showed that,compared with T1（ ck）,the four treatments（ T2,T3,T4,T5） were beneficial to the number of panicles and grains per spike,the highest yield of early rice and late rice was 6. 39 t/ha and 7. 88t/ha,respectively. At the s...
