- 摘要:
- 为促进盐碱地快速改良和高效利用,以不施肥(T0)、常规施肥(T1)、化肥配施(T2)处理为对照,研究化肥配施有机物料[化肥配施生物炭有机肥(T3)、化肥配施秸秆有机肥(T4)、化肥配施秸秆有机肥和生物菌肥(T5)]对水稻产量和品质的影响。结果表明,化肥配施有机物料能降低土壤pH和电导率,有利于盐碱地土壤改良,与未施有机物料处理相比,化肥配施有机物料对水稻增产效果明显,化肥配施秸秆有机肥和生物菌肥(T5)产量最高;龙稻21增产范围为12.76%~189.87%,海稻2号的增产范围为88.46%~151.40%;施用有机物料使穗长变长,穗粒数增多,株高、实粒重、结实率、千粒重均高于未施有机物料处理,穗数、穗粒数、结实率和和千粒重4个产量构成因子与产量呈极显著正相关,相关系数大小依次为穗粒数>结实率>穗数>千粒重;在保证产量的前提下,化肥配施不同有机物料能提高稻米的加工品质和食味值,降低蛋白质含量,化肥配施生物炭有机肥(T3)处理稻米的整体品质最佳。
- Abstract:
- In order to promote the rapid improvement and efficient utilization of saline-alkali soil,in this experiment without fertilization(T0),conventional fertilization(T1) and combined application of chemical fertilizer(T2) were used as control to study the effects of combination of organic material and chemical fertilizer[biochar organic fertilizer with chemical fertilizer(T3),straw organic fertilizer with chemical fertilizer(T4),straw organic fertilizer and microbial fertilizer with chemical fertilizer(T5)] on yield and quality of rice.The results showed that soil pH and electrical conductivity were decreased by using combination of organic material and chemical fertilizer,which were beneficial to saline-alkali soil improvement.Compared with the treatment without organic material,rice yield were increased by chemical fertilizer combined with organic material.The highest yield was chemical fertilizer combined with straw organic fertilizer and biological bacterial fertilizer(T5).The theoretical yield of Longdao 21 increased range was 12.76%-189.87%,and that of Haidao 2 was 88.46%-151.40%.The treatment combined with organic material had the longer panicle length,more grains per panicle,plant height,grain weight,the seed setting rate and 1 000-grain weight were higher than those without the organic material treatment.The correlation coefficients between the four yield components and yield were the grains number per panicle>the seed setting rate>the number of panicles>1 000-grain weight.On the basis of ensuring yield,the application of chemical fertilizers with different organic materials could improve the processing quality and taste value of rice,and reduce the protein content.The rice quality was the best treated with chemical fertilizer combined with biochar organic fertilizer.
