Effects Of Juglans Regia ‖ Crocus Sativus Intercropping On Its(Crocus Sativus) Yield,Quality And Soil Microbial Quantity

To clarify the effect of Juglans regia‖Crocus sativus intercropping pattern on Crocus sativus yield,quality and soil microorganisms,in this trial,at 5 years,10 years and 15 years of Juglans regia forest(H5,H10,H15)as the research object,Crocus sativus single was used as a control,taking the experimental design of random blocks,by measuring the number of microbial bacteria,fungi,and actinobacteria in the paired soil,comparing the differences in plant height,seed ball yield,single ball weight,filament yield and quality of Crocus sativus under Juglans regia forest in different years,exploring the influence of Juglans regia forest intercropping patterns on the biological characteristics,yield and quality of Crocus sativus,through the principal component analysis of 9 biological traits and 4 quality indicators in Crocus sativus,the best intercropping pattern was selected.The main study results are as follows:1.The influence of Juglans regia intercropping on soil microbial quantity showed that in the growing period of Crocus sativus field,the change pattern of soil microbial quantity showed a trend of increasing first and then decreasing,and reached the peak in march,the total amount of H15 microorganisms was33.2×10~5cfu/g,It was 1.55 times and 7.27 times that of Crocus sativus and 15-year Juglans regia singles,respectively.2.The results of biological characteristics and yield of Juglans regia intercropping on Crocus sativus show that saffplant height in intercropping mode,biological trait indexes such as seed sphere yield,weight,diameter and number of main buds of seed sphere,both were significantly different when compared to the CK,different intercropping modes have the highest biological indexes of each species sphere in H10 mode;The yield results of Juglans regia intercropping show that the number and length of main buds,number of flowers,yield,filament length of Crocus sativus,and single ball weight and diameter,the larger the planting ball,the more the number of main buds,the longer the bud height is;The larger the planting ball,The more flowers there are opened,the longer the filament length,the the filament yield.3.The quality evaluation results of Crocus sativus under the Juglans regia intercropping mode showed that the biological characteristics of Crocus sativus affected the content of Crocus sativus and Crocus sativus,with the total content of H10,24.41%,6.05%compared with CK.Through principal component analysis of 13 indexes shigher uch as yield and quality,two main components were H10 with3.431 and CK comprehensive score was-3.067.Considering the factors of bulb production,filament yield and quality of Crocus sativus,it is preliminarily believed that the planting mode of Crocus sativus with Juglans regia is better than that of single planting with Crocus sativus,among which the mode of 10 years of Crocus sativus is the best.
