    Abstract:

    In order to study vine trees absorption and utilization of nutrition at different growing stages, we used 4yearold Muscat Hamburg as material set 1.5 times, 1.0 times and 0.5 times as compared concentrations Hoagland nutrient solution and studied the effects of different nutrient supply on mineral elements and water absorption in Muscat Hamburg. The results showed that: (1) the absorption of mineral elements increased with the growth of shoots and rise in the first stage and then decrease; the maximum absorption amount appeared in the period from the expansion to maturity of berry. In whole growing stage, the absorbing amount of Ca is the biggest and about 1.38 times of P, 4.55 times of Mg, 1.24 times of K, 1.13 times of N. N and K follow by while Mg and P with the least amount, the absorption ratio of N∶P∶K∶Ca∶Mg is 1.1∶0.9∶1∶1.25∶0.26. The absorbing amount of Fe and B are the biggest in microelements. (2) The absorption of every element shows: 0.5 times <1.0 times<1.5 times and the growth of shoots and the quality of fruit is best under 1.0 times. (3) The annual elements absorption of single grapevine under 1.0 times are:N 44.294 g,P 3.456 g,K 37.743 g,Ca 47.728 g,Mg 10.801 g,Fe 210 mg,Mn 46.11 mg,B 79.13 mg,Zn 23.56 mg,Cu 17.104 mg and water 631.5 L.Determine the application amount of mineral elements according to the mineral elements absorption in different stages, during vegetative growth stage, to mainly apply N and Ca fertilizers, accompanying with Mg fertilizers; in reproductive period, to add K fertilizers as well as appropriate amount of trace elements to the nutrient solution.
