Screening Of High Yield And Good Quality Germplasm Resources Of Ramie And The Research Of Biological Degummingtechnology Of Fresh Ramie

Ramie is a kind of important leaf fiber crops. The fibers are excellent in the fiber author fibers. Is the important raw materials of textile industry. With its unique advantages and uses in the national economy plays an indispensable role and replace it. While the existing varieties of fiber ramie textile and high quality to meet requirements of products, fine thin. This experiment on the nursery school germplasm ramie of ramie99germplasm agronomic characters and quality were analyzed and evaluated to screening of agronomic characters and yield integrated good germplasm resources.1.The main research results are as follows:The screening of germplasm resources:In2009,screening of germplasm with high yield of14(single stump yield=100g), The Ma family were1、12、13、16、21、24、30、31、38、48、50、51、68、70、72、73、74、87、88、89、100。. Five of them were high-quality high-yielding varieties, namely. Boehmeria nivea on the3rd、1、13、24、31、70. Single stump in yield and fiber fineness were0.147kg、0.140kg、0.129kg、0.148kg�'�0.169kg and2229m/g、2124m/g、2200m/g、2468m/g、2130m/g。Comparison of different strain:In2011, four high fineness germplasm(1、16、12、21), three high yield germplasm(1、13、00)and one High yield and good quality germplasm (1)were screen through the experiment strain comparison. Single stump in yield and fiber fineness of1were235.8Kg/mu and2668m/g.2.Machine stripping fresh ramie enzyme degumming wasteaterquality and fertil izer use efficiencyFrom the test results that head hemp,first、secondramie processing time of24hours and third ramie processing time of42hours, enzyme dosage respectively machine peeling fresh linen weight2%ramie peeling fresh hemp degumming machine best effect, low cost. The wastewater generated indexes (COD, N, P, K) have reached the national agricultural irrigation water standard, can be used as agricultural irrigation. Biological enzyme degumming wastewater returning on soil nutrients (N, P, K) did not significantly influence; biological enzyme degumming wastewater after returning to follow-up of Crop Agronomic Traits and yield influence.
