The Screening Study Between Strawberry Varieties In Ledu

Ledu of the geographical position is 102.40 ° east longitude, latitude 36.48 °, belongs to the inland semi-arid climate. In the region sunny, abundant groundwater, not cold not hot, the air quality is good, which very suitable for cultivation of high quality strawberries. But single strawberry varieties in the region, cannot meet the needs of many consumer groups. To solve the problem, I designed a strawberry varieties comparison experiment, in order to choose the suitable for planting in the region of strawberry varieties.The experiment with NingYu, Hong xiutianxiang, Yue li three strawberry varieties as experimental material, with introducing Li yinv to check varieties. During the trial by the biological characteristics of four different varieties of strawberry, phenophase, fruit quality, yield and other comprehensive characters and comparative analysis, select the optimal cultivation and promote the best local varieties.The results show that under the same condition of planting and management:1. In the same culture condition, the measuring NingYu during the period of change is minimum, the plant height and crown diameter are 1.85 cm, 0.95 cm * 1.64 cm, are less than control.In guiding the cultivation can improve the planting density appropriately;2. The phenophase compareNingYu with in contrast were similar, the last to harvest stage only a day later than control, they are and the more beautiful to harvesting stage time is compact, but add red sweet eight days later than the contrast;3. The disease resistance, Hong Xiutianxiang for strawberries rotten fruit disease, powdery mildew and the incidence of grey mould of the lowest, 50.84%, 11.90% and 3.45% respectively, compared with lower by 33.61%, 32.31% and 48.53%, respectively, have significant difference;Followed by the incidence of NingYu, 59.10%, 27.95% and 14.66% respectively, and contrast compared also had significant difference;The highest rates, compared with the control except there is no significant difference between strawberry rotten fruit disease, powdery mildew and gray mold all have significant difference;4. The fruit quality, NingYu, Yue Li are better than that of control, Hong Xiutianxiang on the water resistance is better than control;5. The early determination of plot yield, Li Yinv was 6.65 kg;NingYu was higher than the control 1.36 kg, there is no significant difference; Hong Xiutianxiang is 20.61 kg higher than the contrast and significant difference between; Yue Li than controlled low of 0.21 kg, there is no significant difference; 6. Comprehensive above index, think red Hong Xiutianxiang and NingYu comprehensive quality is best, suit in Le Du accumulates promotion.
