Problems solved by technology

The cultivation of grafted seedlings is also disturbed by climate factors, and the cold-resistant rootstock seedlings can only be planted in the first year, and grafted in the second year. However, due to the short growth period, the degree of lignification of the grafted seedlings is relatively low, so the survival rate is not high ( The so-called "survival rate is not high" refers to the survival rate of plants that survived the winter.
) In this way, the investment in viticulture is relatively large, and the effect is too late

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with specific embodiments.

[0011] On March 1 every year, soak the rootstock branches and variety branches stored in winter for 20-30 hours respectively, cut the lower part of the rootstock branch obliquely at 1 cm opposite to the lower bud, and cut the upper part at 3-5 cm above the terminal bud Cut, the length is 30 cm, and the thickness is preferably 0.6 to 0.8 cm. The branch of the variety should choose the one with full bud eyes, leave 1 cm above the bud, and leave 3 to 5 cm below the bud to cut. Rootstock branches and variety branches are required to be short, green, fresh and nutritious; hard branch grafting is carried out, and the interface is tightly wrapped with film while grafting.

[0012] According to the thickness of the grafted branches, every 20 or so, the lower ends of the branches are neatly bundled into handles, and placed in rows in the seedling trough one by one, leaving a gap ...

Abstract

The invention discloses a three-way rapid cultivation method for grape seedlings in the northern region, which comprises the following steps: a grafting step; a seedling raising step; a cutting step: in a solar greenhouse, a nutrition bag is installed in advance, the nutrition bag has a diameter of 7-8 centimeters and a height of 15 centimeters, After the cuttings are managed in the greenhouse, they can be planted in the open field in about 60 days to build a garden. The technical solution of the present invention is to use the solar greenhouse to advance the grafting of seedlings to March, so that the growth period of the grafted seedlings is advanced by 60 to 90 days. Among the subspecies, Pollet and other varieties with branches that are easy to grow green, the growth period is extended from about 130 days to 190-220 days, and they can fully achieve a good lignification degree, so they can survive the winter safely.

Description

technical field [0001] The invention relates to a three-way rapid cultivation method for grape seedlings in the northern region, and belongs to the field of agricultural technology. Background technique [0002] The climate in northern China is cold and the frost-free period is short, which greatly limits the good development of the viticulture industry. Taking Datong, Shanxi as an example, it is particularly affected by climate. The grape cultivation in Datong area can only be unearthed on April 20th every year, and can only germinate after May 1st. In the year of severe spring cold, the germination will be later. At the same time, due to the low temperature, the growth is very slow. At the woodiness level, it has entered mid-June, and the local climate is on the eve of October 1st every year, most areas have been frosted and leaves withered, and the grafting time is very short. After June 20th, the seedlings grafted except European and American hybrids such as Kyoho and r...
