摘　　要：为考察有机底肥量、丛内密度、株距、行距等4个因素对无化学合成物投入的稻谷栽培的影响,寻找无化学合成物投入的稻谷栽培新途径。通过选用L934正交表设计并布置4因素3水平的9种无化学合成肥料农药除草剂投入的稻谷栽培模式的正交试验,经过分析对比产量,寻找出符合生产实际的无化学合成物投入的稻谷栽培新模式。在试验条件下研究筛得的最优试验组合是相当于标准量的1.5倍量有机肥即兔粪0.75 t/666.7 m 2,即折合纯氮16.13 kg/666.7 m 2,丛内栽2苗,株距10 cm,行距30 cm;结果表明形成的无化学合成物肥料农药除草剂等生产投入的新法为稻谷生态绿色有机栽培提供了新技术与新途径。能够轻简高效给生产创造经济和生态及社会效益,极有现实推广意义。In order to investigate the effects of four factors such as organic bottom fertilizer,density within the bush,plant spacing and row spacing on rice cultivation without chemical synthesis input,a new approach to rice cultivation without chemical synthesis input was sought.Through the design of orthogonal table L934 and the arrangement of orthogonal tests of 9 rice cultivation modes without input of chemical synthetic fertilizers,pesticides and herbicides at the level of 4 factors and 3 levels,through the analysis and comparison of yields,a new rice cultivation mode without input of chemical compounds in line with the production practice was found.Under the experimental conditions,the optimal test combination obtained by screening was 1.5 times the standard amount of organic fertilizer,namely 0.75t/666.7m2 of rabbit manure,namely 16.13kg/666.7m2 of pure nitrogen.Two seedlings were planted in the cluster,with plant spacing of 10cm and row spacing of 30cm.The results showed that the new method without chemical synthetic fertilizer,pesticide,herbicide and other production input provided a new technology and a new way for the ecological green rice cultivation.It is a comprehensive technical mode to achieve balanced and safe production by means of agricultural cultivation,such as disinfection of warm soup of seeds of normal varieties at the mature stage,arrangement of sowing and planting period,full layer fertilization before planting,line direction roughly following the main wind direction of the growing season,close planting size wide line and narrow plant configuration,soil moisture regulation and so on.It can comply with the development trend of agricultural mechanization and the safety demand of government and social consumers for environmental quality and product quality.It also can adapt to the current situation of agricultural labor force,no new high requirements for the quality of practitioners,without a lot of training,easy to be farmers and other practitioners understand and accept;It can effectively save wat
