The selection of plant varieties and rootstocks should follow the following principles.
1. Select early-maturing or very early-maturing varieties that require cold and low-calorie, short-fruit development period for early winter-plowing cultivation and spring-to-early-climate cultivation; select multiple varieties with strong fruitability for early-on-season cultivation; A late-maturing or very late-maturing variety with a long fruit development period was selected for delayed cultivation.
2. Choose early-shine Fung products that are resistant to weak light, flower buds are easy to form, have low bioticity, high fruit setting rate, and continuous fruiting ability, in order to facilitate the increase of yield and annual output.
3. Select the species with moderate growth potential or use dwarf rootstocks to easily adjust the size of the tree and apply it to dense planting.
4. Select varieties with moderate tightness, uniform and consistent fruit size, high quality, color and storage, and pay attention to increase color varieties to overcome the problem of simplification of varieties to increase market competitiveness.
5, coloring varieties need to choose a good coloring conditions under scattered light conditions, to adapt to the direct light within the facility to reduce, is not conducive to grape fruit coloring of the weak light conditions.
6, choose a variety of ecologically adaptable, and disease resistance and strong resistance varieties or the use of reversible rootstock, in order to facilitate the production of pollution-free fruit.
7, according to the need to select the use of grafting and scion grafting affinity is good, and has resistance to grape phylloxera, anti-nematode, saline-alkali, acid-resistant soil, anti-double glutinous, cold resistance, drought resistance, resistance and other resistance, energy Improve the scion varieties of fruit. Quality, multi-resistance rootstocks with early or delayed characteristics such as fruit ripening of scion varieties.
8. When planting varieties in the same greenhouse, the same variety or varieties of the same variety group that are basically the same in maturity should be selected so as to facilitate unified management; and when different types of varieties are selected in the greenhouse, they can be appropriately matched so that early, middle, and Late maturing varieties are available.
