Method for improving space utilization rate and seedling quality of young grapes

Abstract

The invention provides a method for improving space utilization rate and seedling quality of young grapes, which comprises the following steps: in the first year, after the grapes sprout in the first year, reserving a robust new shoot at the top end, arranging three iron wires, vertically binding the new shoot on the first iron wire after the new shoot grows to 50cm, removing all growing points below the first iron wire, and reserving 1-2 auxiliary shoots at the top end of the new shoot; when the auxiliary shoots grow to 10 cm, the auxiliary shoots are horizontally bound along the first iron wire, and pinching is conducted after the auxiliary shoots grow to 60 cm; when young sprouts grow to 120 cm, the young sprouts are horizontally bound along the second iron wire, and when the young sprouts grow to 150 cm, pinching is conducted. In the second year, the main vines are horizontally bound at the first iron wire and the second iron wire, and the base parts of the main vines and the ground form included angles of 70-80 degrees; removing one iron wire and all growing points of the longitudinal main vines between the first iron wire and the second iron wire, reserving selected shoots on the transverse grape main vines of the first iron wire and the second iron wire, and pinching and removing other axillary buds according to the difference of the types of new shoots in the current year, namely bearing branches and vegetative branches. Space is utilized, the thickness of main vines is increased, and nutrition and reproductive growth are both considered.

Description

technical field [0001] The invention belongs to the technical field of grape planting, and in particular relates to a method for improving the space utilization rate of young grapes and the quality of seedlings. Background technique [0002] After the grape seedlings are planted, it is necessary to determine the required cultivation posture according to the cultivation area environment, which plays a vital role in the growth, high yield and fruit quality of the grapes. Traditional cultivation postures are divided into hedgerows and trellises. Although the trellis has a large frame area and a wide range of results, it has high material costs, a large one-time investment, and is difficult in pruning and pest control. The hedgerow frame is easy to manage and beneficial to Buried in the soil, the ventilation is good, and the yield per unit area is high. Traditional wine grapes are mostly planted with hedgerows. [0003] In order to achieve premature and high yield, usually in t...

Problems solved by technology

Although this method can promote the early harvest of grapes, it has the following 3 deficiencies: (1) the space utilization rate is not enough

Because the angle between the main vine and the ground is too small too early, the advantage of the top is not obvious, and the growth rate of the main vine is low, which leads to production problems such as freezing injury and dry hot air drying branches in northern areas, which affects the survival rate of afforestation

(3) Chaos

The new shoots grow too densely, and it is easy to germinate twice or even multiple secondary shoots, resulting in too thick leaf curtains, affecting ventilation and light transmission, causing diseases and insect pests, and increasing pruning labor costs
