In order to explore the changing law of dry direct-seeding rice quality under different organic fertilizer treatments,this experiment was conducted from 2018 to 2020.Longjing 31 was used as the test material.Treatments includes:zero fertilizer(N0),conventional fertilization(NPK),Biochar+conventional fertilization(OF1),seaweed bio-organic fertilizer+conventional fertilization(OF2),Jishiwang bio-organic fertilizer+conventional fertilization(OF3),attapulgite organic fertilizer+conventional fertilization(OF4).Changes in the processing quality,appearance quality,nutritional quality,and cooking and eating quality of dry direct-seeding rice were investigated.Compared with NPK,the head rice percentage of OF1,OF2,OF3,OF4 increased by 2.64 ,1.78,1.06,2.53 percentage points,respectively.The chalkiness degree of OF2 was the highest(1.82%),which was 0.11 percentage points higher than that of NPK.However,the chalkiness degree of OF1,OF3 and OF4 were lower than that of NPK,with an average decrease of 0.26,0.41,0.51 percentage points,respectively.There was no significant difference in grain length,grain width and length width ratio among the treatments.From 2019 to 2020,compared with NPK,organic fertilizer treatment increased protein content,but decreased amylose content;the protein contents of OF1,OF2,OF3 and OF4 were 8.99%,9.13%,9.08% and 9.16% respectively,which were 0.54,0.68,0.63,0.71 percentage points higher than those of NPK;the amylose content of OF1,OF2,OF3 and OF4 decreased by 0.20,0.64,0.69,0.38 percentage points,respectively;compared with NPK,the application of organic fertilizer at the initial stage could improve the luster,taste,flavor and taste value of dry-direct seeding rice,but long-term application of organic fertilizer would lead to poor cooking and eating quality;from 2019 to 2020,the average taste value of NPK treatment was 72.70,compared with NPK,OF1,OF2,OF3 and OF4 reduced the aroma,luster,taste,flavor and taste value of dry direct-seeding rice by 5.53%,6.40%,3.71% and 3.23%,respectively,but organic fertilizer increased the integrity of rice.In conclusion,long-term application of organic fertilizer can improve the processing quality,appearance quality and nutritional quality of dry direct-seeding rice,but it is not conducive to the formation of cooking and eating quality and reduce amylose content.
