Abstract

In this study, the nursery of the Agricultural University of Hebei , introduction and cultivation and adaptability on of Echinops and the woody Elsholtzia two kinds of wild flowers , the results showed that: (1) Echinops seed germination rate, germination potential are high different germination temperatures and different soaking temperature effect is not large . The outdoor temperature at 15 ° C to 20 ° C to 50 ° C to 60 ° C water soaking treatment of its seeds , planting seedlings , can be earlier to obtain uniform germination rate . Germination temperature on the woody Elsholtzia seed germination rate , the different temperatures water woody Elsholtzia seed soaking treatment has little effect on the germination rate . The outdoor temperature at 15 ° C to 20 ° C with 50 ° C water on the woody Elsholtzia seed soaking treatment planting seedlings , planting seedlings , can be earlier to obtain uniform germination rate . (2 ) Echinops March to late planting after mid-April began to germinate in early May to germinate and grow full leaf . In mid-June to form a more complete plants . Mid-October , the end of the aerial parts of leaves began to yellow . Sowing of the woody Elsholtzia late March , late April began to germinate in mid-May all germinate and grow a complete set of true leaves . In mid-June to form a more complete plants . 10 mid- enter the withered period . ( 3) Echinops able to adapt the type of illumination , and the soil level , wide adaptability , can be cultivated in different environments . Woody Elsholtzia on different light , soil adaptability, can be cultivated in different environments , but different light intensity would woody Elsholtzia plant height . (4 ) two wild flowers in the soil salt concentration of 0.1% , 0.3% under all conditions is long growth , when soil salt content > 0.5% , the two wild flowers can not survive . (5 ) determination of membrane permeability changes in the gradient at high temperature , calculated Echinops semi- lethal temperature was 62.41 ° C , the woody Elsholtzia the semi - lethal temperature for by 60.98 ° C .
