Résumé
As test materials, 2-year-old Red Globe grape seedling in greenhouse cultivation under the conditions of the arid desert region of Linze County, Gansu Province, in order to promote the growth and development of the reproductive period of grape leaves and slow off premature aging yellow, to improve grape fruit quality so as to improve the grape plants in the adversity of drought, high temperature resistant, to delay grape harvest time, to obtain a higher economic efficiency, different times and different number of growth regulators during the grape growing pack fruit excellent and Micronutrient Fertilizers pack fruit good \The main results are as follows : 1. Treated with different concentrations, different number of package fruit excellent \longitudinal, transverse diameter and chlorophyll content were improved, especially in the hot season in July and August, ck shoot growth, the vertical and horizontal diameter of the blade, the chlorophyll content of growth is very small, but all treatments continued growth higher than ck. Late when ck blades completely aging, the chlorophyll content of the various processing still higher than ck, delayed leaf senescence processing package fruit excellent \and bracteata Fruit (707) \Growing season package fruit excellent \reduced malondialdehyde content : pack fruit excellent 800 times, 1000 times, 1200 times the processing compared with ck improve the content of free proline, peroxidase activity, superoxide dismutase activity, and lower propylene dialdehyde content. concentration in treatment effect as well, \264.64%, 223.1%, 76.16% ; superoxide dismutase activity and ck increased compared to 44.89%, 25.51%, 24.03% ; peroxidase activity compared with the control by 300%, 333.33% and 300% ; malondialdehyde content and ck reduce 50.15%, 28.32%, 29.52% by pack fruit good \to fruit processing (707) 500 times 3 times, 500 times 3 times \147.61%, 168.88% ; superoxide dismutase activity and ck increased compared to 26.53%, 33.39%, 33.4% ; peroxidase activity compared with the control by 300%, 300%, 486.66% ; malondialdehyde content ck compared to 13.06%, 21.29%, 42.41%. Before flowering by the \\percent, 2.77 percent, down 1.86 percent titratable acid ; \sugar content compared to an increase of 10.4%, 9.51%, 11.23%, 1.97%, 1.69%, 2.32%, titratable acid content reduced by 1.38 percentage points ; pure \rate of fruit set, fruit length, transverse diameter, Vc, soluble solids content, soluble sugar content than ck, an increase of 8.28 percentage points, 7.22%, 11.65%, 45.26%, 1.41%, 0.65%, titratable acid content reduce 2.16% ; fruiting rate \%, 35.92%, 1.68%, 4.38%, titratable acid content reduced by 2.52 percentage points.
