CN104012219A - Bud carving technology for promoting pear seedling central trunk to have multiple branches - Google Patents

Abstract

The invention relates to a bud carving technology for promoting a pear seedling central trunk to have multiple branches. According to the bud carving technology, multi-position bud re-carving is carried out on a strong single trunk pear seedling before germination so as to obviously increase a branch growing quantity on the central trunk; the growth vigor of the upper and lower branches is uniform and flower buds can be formed at the tops of almost branches, so as to be good for culturing a long-and-thin and narrow-crown tree form. The bud carving technology is suitable for being popularized and applied in pear gardens adopting labor-saving, efficient and modern cultivation patterns.

Description

A kind of bud technology at quarter that inspires the dry multiple branch in Li Miao center

Technical field

The present invention relates to the bud technology at quarter of the dry multiple branch in a kind of Li Miao of inspiring center.

Background technology

China is in theatre is set up in the past, and adopt gone alone seedling planting more, although sometimes also adopt and carve bud technology, mostly is orientation and inspires major branch, carves bud negligible amounts.Cause treelet to send out a negligible amounts, the branch inspiring is longer, enters fruiting period and high yield period more late.

According to inventor herein, test, adopt laborsaving, efficient, the modern cultivation mode of pears, utilize big stock grafting to cultivate capable and experienced strong sprout, next year is the dry upper method that adopts multidigit heavily to carve bud of the heart therein, can effectively improve and send out branch quantity, be convenient to " elongated narrow hat " tree-like cultivation, done sth. in advance significantly result and high yield period.

Summary of the invention

The present invention has created and a kind ofly on capable and experienced pears seedling, has carried out the method that multidigit is heavily carved bud.

The technical solution adopted for the present invention to solve the technical problems is: on capable and experienced pears seedling, adopt multidigit heavily to carve bud technology, can improve quantity that pears treelet sends out branch and the uniformity of branch growing way, become flower quantity many, be convenient to " elongated narrow hat " tree-like formation.

Particular content of the present invention, on capable and experienced pears seedling multidigit heavily to carve the method for bud as follows:

1, carve bud object: the annual nursery stock that utilizes large stock grafting to cultivate, height is more than 160cm, and on seedling grafting mouth, 5cm place diameter is more than 1.5cm.

2, carve bud period: spring, Sprout period carried out in the last week.

3, carve bud method: except nursery stock base portion 50cm and top 30cm do not carve bud, the dry all bud counterpoises in center are carved to wound.Carve bud instrument and can adopt wallpaper cutter or long handle scalpel.Carve 0.5cm place above bud, bud position, hinder length quarter is 1/2 ~ 3/4 of branch girth, and otch reaches xylem deeply.

4, bud picking and angle of release: center is dry carves after bud, for all sprout tillers of sprouting within the scope of butt 60cm, will erase in time.The length of sending on dry for center is greater than the young sprout of 45cm, with toothpick or by plastic ties, angle is opened to 70 ° ~ 90 ° in time.

The beneficial effect of patent of the present invention is: by adopting bud method at quarter of the present invention, pears treelet sends out a quantity and significantly improves, and the branch uniformity increases, and is more conducive to " elongated narrow hat " tree-like cultivation.

Embodiment

2004 ~ 2012 years, on Gaoyang, Hebei, quay, Linzhang and other places, set up in the process of laborsaving, efficient, modern cultivation mode theatre, for utilizing going alone strong sprout of big stock grafting cultivation, before Second Year rudiment in spring, adopted multidigit heavily to carve bud technology.According to the investigation on ' No. 7, new pears ', show, by carving bud, biennial tree individual plant branch amount reaches 47 ~ 52, and wherein brachyplast accounts for 12.8%; Middle branch accounts for 31.9%; Long shoot accounts for 55.3%.Most branches top all can form bud.And the branch polarization of adjoining tree pumping is serious, Cheng Hualiang is few.

Claims (1)

1. a bud technology at quarter that inspires the dry multiple branch in Li Miao center, is characterized in that comprising following step:

(1) carve the annual pears height of seedling of bud Object Selection degree more than 160cm, 5cm place, grafting mouth top diameter, more than 1.5cm, is gone alone without branch;

(2) carve bud scope except nursery stock base portion 50cm and top 30cm, all the other all lateral buds are all carved bud and are processed;

(3) carve bud position and degree and carve 0.5cm place above bud, bud position, hinder length quarter is 1/2 ~ 3/4 of branch girth, and otch reaches xylem deeply.
