Abstract

The present invention discloses a grapefruit dwarfing cultivation method. The method mainly comprises the following measure that high pressure seedlings of a grown grapefruit tree are used as materials for the dwarfing cultivation of grapefruits during seedling cultivation. A water solution of indoleacetic acid or indolebutyric acid or naphthylacetic acid is uniformly spread at the girdling mouth of the cultivation materials, and drying for 1 to 2 days is carried out; clay and an organic fertilizer are uniformly stirred by water and made into soil balls for binding the girdling mouth, and the girdling mouth is then wrapped by plastic films; the moisture of the soil balls is kept; when new roots are grown on the high pressure seedlings, and the tawny color is obtained, high pressure branches are sheared and placed into a nutrition bag; 1 to 2 months later, the temporary planting survival of the high pressure seedlings is realized, and cultivation through field planting is then carried out; necessary trimming is carried out on the grapefruit tree.

Description

A kind of method for dwarf culture of pomelo

Technical field

The present invention relates to the culture technique of the culture technique of a planting fruit-trees, particularly shaddock.

Background technology

The plantation of shaddock, origin is of a specified duration the sixth of the twelve Earthly Branches, still lacks further investigation but in the prior art shaddock is downgraded growing and cultivation.The dwarfing culture that has of idol is also just downgraded in the early stage of teak usually, and it is strengthened prune that to control the tree height big.Later stage is then tall and big gradually because of setting body, operating difficulties, and the moon degree of covering is big, thereby has lost the effect of teak dwarfing itself, and the end fundamentally makes the teak dwarfing, the therefore also last purpose that really reaches the shaddock dwarfing.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art, provide a kind of simple to operate, cost is low, the result early, instant effect easily obtains the method for dwarf culture of pomelo of nursery stock.

Purpose of the present invention can realize by following measure:

1, in annual May～September, the material of the high pressure seedling (being overhead layering) of teak in age as dwarf culture of pomelo adopted in the cultivation of nursery stock.

2, choosing biennial or give birth to the branch with the above robust growth of two branches then is propagating materials, 3～4 centimetres of one section band girdle length, with scraper scraping epidermis and cambium, forms the band girdle mouth of an overhead layering.

3, adopting concentration is that draw the indolylbutyric acid aqueous solution or the concentration of 300PPM is that the water-soluble or concentration of the indolebutyric acid of 200PPM is the aqueous solution of the methyl of 200PPM, is coated in described band girdle mouth place equably, the cool solarization 1～2 day.

4, clay and organic manure water are mixed thoroughly made native bag and tie up the band girdle mouth place, get final product with plastic film wrapping band girdle place again; The weight ratio of described materials is a clay: organic manure: water=7: 1: 2.

5, keep the humidity of described native ball,, spray water immediately to replenish native ball moisture content in case find native ball dehydration.

6, when the high pressure seedling grows new root to yellowish-brown, can cut the high pressure branch.

7, using nutritious bag--15cm * 20cm made from polyethylene has an end bag film, and the weight ratio of packing in bag then is a clay: organic manure: the nutrition soil of water=7: 1: 2 is nutritious bag.The high pressure seedling nutritious bag of packing into, heel in the seedbed, give 30%～50% and shelter from heat or light, and keep nutritious bag matrix moisture content.

8, plantlet of high pressrue is heeled in and is survived after 1～February, can the field planting cultivation.

9, after field planting survives, all to regularly or irregularly prune, can obtain required dwarfing grapefruit teak from treelet to bearing-age tree.

Compared with prior art, the present invention has following outstanding advantage:

1, cultivation practices shows, the nursery stock that using said method is cultivated has the result early, instant effect, and cost is low, and tree-like dwarfing is simple to operate, easily obtain nursery stock.And by it reasonably being pruned and shaping a series of agronomic culture measures such as control of rich water quality management and damage by disease and insect, the dwarfing culture achieving success of shaddock.

2, big according to teak tree height, characteristics such as cloudy worn-out degree is big, in the cultivation of nursery stock, adopted the high pressure seedling as the dwarf culture of pomelo material, the dwarfing effect is obvious, downgrading highly only is below 1/2nd of former teak, and, so fundamentally solved the big technical barrier of teak later stage tree height, for the teak dwarfing culture lays a solid foundation to its shaping of selectively pruning.

3, the dwarfing culture of shaddock has advantages such as premature labor, bookkeeping be simple, it is the development trend of shaddock cultivation from now on, the enforcement of this technical scheme is promoted, and to the development and use of the peculiar fruit tree in western part, shaking off poverty and setting out on the road to prosperity of the mountain area people is had good economic benefit and social benefit.

Embodiment

Embodiment 1

In early August, being selected to the robust growth of teak in age and having the complete lignified branch of two branches is propagating materials, 3～4 centimetres of one section band girdle length, with scraper scraping epidermis and cambium, form the band girdle mouth of an overhead layering, employing concentration is that the aqueous solution of the APT of 300PPM is coated in described band girdle mouth place equably, the cool solarization 1～2 day.Clay and organic manure water mixed thoroughly make native bag and tie up the band girdle mouth place, get final product with plastic film wrapping band girdle mouth place again; The weight ratio of described materials is a clay: organic manure: water=7: 1: 2.Keep the humidity of described native ball,, spray water immediately to replenish native ball moisture content in case find native ball dehydration.When the high pressure seedling grows new root to yellowish-brown, can cut the high pressure branch.The high pressure seedling nutritious bag of packing into, heel in the seedbed, give 40% shelter from heat or light, and keep nutritious bag matrix moisture content.Plantlet of high pressrue is heeled in and is survived after 1～February, can the field planting cultivation.After field planting survives, all will regularly or irregularly prune teak from treelet to bearing-age tree, can obtain downgrading highly is the dwarfing grapefruit of former teak height 2/5.

Embodiment 2

Except that described medicament of cultivating nursery stock is that concentration is the IBA of 200PPM, all the other steps are with embodiment 1.

Embodiment 3

Except that described medicament of cultivating nursery stock is that concentration is the NAA of 200PPM, all the other steps are with embodiment 1.
