| In seed germination test, six species, including Highland barley148 and 690, Holly No.1, Guoluo No.19 and Shanqing No.24, were presoaked in"Tian-da2116"with the concentration of 0.7% and 0.5%, and 0.3% respectively and then compared with those presoaked in water, germination percentage and germinability were assayed. In pot experiment, highland barley690 and Guoluo were chosen to test the effects of"Tian-da2116"on the physical and chemical properties of highland barley growth. In field experiment, Guoluo was used to test the effects of"Tian-da2116"on production and related agronomists of highland barley. The three tests told the effects of"Tian-da2116"on the growth of highland barley. The main findings are as follows:1 Different species of highland barley breed acts differently to"Tian-da2116". It can accelerate the seed germination of Highland barley148, Guoluo and Himalayan No.19 but doesn't have obvious effects on Shanqing No.24.2"Tian-da2116"of different concentration has different effects on seed germination.The concentration of 0.3% to 0.5% is better for seed germination.3"Tian-da2116"can improve the photosynthesis characteristic of Guoluo. It can improve net photosynthetic rate, transpiration rate and chlorophyll content.4"Tian-da2116"could increase the moisture content of Highland barley 690's straws to a certain extent, which can increase its fighting against drought.5"Tian-da2116"can improve the quality of Highland barley 690's straws especially the protein and manganese content. The content of protein increased by 30% using A and manganese increased greatly using C and reached a significant level using D treatment.6"Tian-da2116"can increase the production and improve relevant property. In the experiment, all the six treatments increased the production. It reached by 38.07% and 29.49% respectively after the F and B treatments. The main reason is that"Tian-da2116"improved the number of productive ear by promoting the tillering of Dongqing. The grain number per spike, grains weight per spike, grain number per plant, the grains weight per plant 1000-kernel weight and total tillers were increased in both treatments F and B. The production of the barley was improved presoaked in"Tian-da2116". It may because"Tian-da2116"can accelerate the growth of the barley in vegetative growth phase. |
