The Effects On Flower Of Potentila Reptansvar Sericophylla To Different Management Measures

As a new type cover plants with flower,Potentilla reptansvar.sericophylla have these properties.good resilience, more speed in covering, holistic ecological features strong, comprehensive adaptive range and the advantages of beautiful appearance quality.lt with Yellow Flowers in the whole growth period that compared with other groundcover plants, and has a better landscape effect, beautification has very broad prospects.The domestication of wild Potentilla reptansvar.sericophylla as the materia for this experimental,with the different processing methods,physical pruning,hormone treatment,fertilizer treatment in high temperature phase on the flowers,and then conducts the thorough research in view of flower number, the number of node, the node branch number, flower diameter, flower stalk length, petiole length, stolon length, chlorophyll content. The results showed that,1.Physical pruning can promote the flowering of Potentilla reptansvar.sericophylla, improving the flower stalk and petiole length, has distinct effect on the overall view and smoothness. The effect of Potentilla reptansvar.sericophylla after pruning in flowering is obvious, flowering in advance for a week than the herb of don’t trim.In terms of number of flowering reflects a certain differences.Two-thirds clip treatment more than a third clip of the cumulative number of flowering 20/m2 in the peak period.The flower stalk length and petiole length are consistent after pruning. The difference of Color is not obvious.2.1n the test prone to blossom bloom effect with the concentration gradient of GA3 50;100;150 mg/kg to the Potentilla reptansvar.sericophylla are not obvious.but the test of number of flowering, petioles and flower stalk length is more noticeable impact in the results. Among the six weeks in early July to mid August, the treatment of 50 mg/kg flowers number and flowers diameter size are significantly higher than other treatment;And the number of nodes have advantage;branch node number and the chlorophyll content is also higher than other treatment;the treatment of 100 mg · kg herb petioles and flower stalk length is than the other three treatment in the length of the growth effect is obvious.3.The results of fertilizer composite experiment showed that:Potentilla reptansvar.sericophylla in flowering performance is not obvious, but for all kinds of characters exhibits different, the different ratio of N, P, K fertilizer for the entire appearance of the Potentilla reptansvar.sericophylla have different effects on flowering, color and so on.The treatment of N1P1K2 has largest number flowering;The treatment of N2P0K2 more excellent in the flower stalk length and diameter performance;The treatment of N2P1K2 have more mumbers branch node;In the leaf color aspects, the treatment of N3P2K2 is the most abundant in chlorophyll content.As for the other performance is not obvious.
