Embodiment 1

[0033] Embodiment 1, the present embodiment discloses a method for high-efficiency raising seedlings of the new grape variety Yunshan No. 2, which is improved in that it includes the following steps:

[0034] (1) Automatic control of environmental factors: adjust the temperature of greenhouse seedlings through automatic temperature control devices to keep the ambient temperature at 20-28°C to promote rooting of leaf buds; adjust the light intensity of the greenhouse through automatic shading equipment to keep the light intensity at 100- 200lx, which can effectively promote the photosynthesis of leaf buds; adjust the humidity of the greenhouse air and substrate through automatic spraying equipment, so that the air humidity is maintained at 85%-95%, and the substrate humidity is maintained at 60%-70%. external balance;

[0035] The air flow is controlled by automatic air conditioning equipment to keep the air in the greenhouse flowing smoothly and fresh without musty smell;

Abstract

The invention discloses an efficient seedling cultivating method for leafbuds of a Yunshan 2# grape novel variety. The method comprises the following steps: (1) automatic control of environmental factors; (2) maternal plant plantation management of Yunshan 2# grapes; (3) preparation of an in vitro material; (4) treatment of the in vitro material; (5) seedbed inoculation and management; and (6) on-site hardening-seedling and transplantation. By using semi-lignified leafbuds as the in vitro material to cultivate seedlings, the seedling cultivating method disclosed by the invention breaks through the conventional seedling cultivating technological forms such as seeds, cuttage, tissue culture and the like so as to form technical innovation of Yunshan 2# seedling cultivation. The seedling cultivating method disclosed by the invention can realize the following technical indexes: characteristics of the original variety Ziwuhua grape: high yield and bumper crop, stress resistance and the like are ensured, and no variation is available; the seedling cultivating period is shortened to 60 days, and the highest seedling cultivating number of times reaches 6 time; the seedling survival rate reaches over 95%; the cost of Yunshan 2# seedlings can be lowered to 30 yuan/strain.

Description

technical field [0001] The invention relates to the field of seedling raising methods, in particular to a high-efficiency seedling raising method for the new grape variety Yunshan No. 2 in the field. Background technique [0002] Since the end of the 19th century, when grape phylloxera was endangered, European and American countries have generally promoted grape grafting cultivation, popularized non-toxic seedlings, and implemented strict seedling inspection and production systems. The minimum age of vines in France is 40 years, generally 50-70 years. When the grape orchard was built, great attention was paid to the quality of the seedlings, and all the seedlings were grafted seedlings without viruses. There are strict standards for seedlings out of the nursery. Seedling companies all have dedicated ear-picking gardens (2.5m×1.0m row-to-plant spacing) and female parent gardens (2.5m×2.5m row-to-plant spacing), and mechanized grafting methods (5000 plants / person / day).
