The results of the experiment are as follows 1. No. No. No. 4 kinds of forage bred No. No. No. No. compliance and forage research notes, 5, 12, 13 and 14 species in yield, plant height, nutrient character, over summering rate balance of good, may conform to the south of the Yangtze River downstream region meteorological conditions, and comparison of species compared to the gap is not big, is a superior moral capacities of wild white clover, joint phenology observations, this species should be in late February jointing fertilizer, 5 kinds of stubble cutting time is right to dominate in mid April, 12, 13 and 14 species in four month stops at the first time cutting. Yangzhou does not comply with the regional plant No. 3, No. 4, No. 6 species, No. 11 and No. 16 in nutrient character flaws. Nine other wild species of forage quality is not high, however can conform to the Yangzhou region of planting condition, can according to different production purposes, using different methods have chosen to be applied. 2. Ping feature research notes, No. 5, 9 and 16 was the three wild white clover species of Ping use evaluation is the best to reach the good and suitable turf; No. 3, No. 4, 11, 13 and 14, the five kinds of Ping with evaluation as poor, not suitable for turf. The other 10 types of evaluation of turf. Combined with the summer and the summer survival rate and after rejuvenation speed research and analysis, No. 5 and No. 9 types of the most suitable in Yangzhou area as indecent ornamental turf to promote the use of. By a process of 18 accessions of wild white clover leaf area, height and density of the three measured Ping with the goal of analysis of variance, obvious difference from the start, the number of objectives can be divided into five grades, and green period, color and uniformity of three target grade, obtained a relatively suitable white clover turf quality evaluation scale. 3. 18 accessions of wild species, Nianye sector kinds of forage and turf quality is not high, but all follow in Yangzhou area planted; do not comply with the No. 3 and No. 4 and No. 6 kinds of Yangzhou region of low temperature weather; No. 12, 13, 14 species in compliance, feeding on said excellent, but turf value is not high; 9, 16 species in the Ping value indicated excellent, but feeding value is not high; No. 5 is forage and turf all excellent species, suitable in Yangzhou area planted application. 目录: |
