Abstract:
‘Beibinghong’ grape was used as the test material, the method of random block group was adopted, and 6 fertilizer treatments were set, the effects of different fertilization amounts on yield, quality and nutrient absorption of ‘Beibinghong’ grape were studied, in order to provide reference for rational fertilization of ice vineyards.The results showed that, different treatments could significantly promote the absorption of nitrogen, phosphorus and potassium in ice grape plants, improve the utilization rate of fertilizer and increasing the growth of new shoots of plants.The basically showed that low fertilization(treatment 1) was better than medium fertilization(treatment 4),high fertilization(treatment 5) and no fertilization(CK).Different fertilization amounts also affected the improvement of ice grape yield and quality.Compared with non-fertilization, several other fertilization amounts could increase yield of ice grape to a certain extent, and the yield would not increase with the increase of fertilization.In the five fertilization gradient, the yield of medium fertilization was the highest, followed by higher fertilization.Secondly, the yield with the lowest fertilization amount was higher, and there was no significant difference between these three treatments.There was no trend in the effect of different treatments on quality.Among the five fertilization gradients, the highest glycolic acid ratio was found by the highest fertilization, followed by the higher glycolic acid ratio by the lowest fertilization, followed by the higher glycolic acid ratio of the control.There was no difference between different treatments on the tannin content of fruits.
