Abstract

A seedling culture method for a new blueberry product suitable of instant eating comprises the steps of selecting a blueberry product, namely Berkeley, as a male parent, and selecting blueberry product, namely M7, as a female parent; carrying out tissue culture on stem tissues of M7 and leafbud tissues of Berkley, and carrying out redifferentiation induction to form plants; culturing plants which grow well for cuttage; and carrying out cuttage on the plants on a culture medium for 3-6 months to obtain new blueberry plants suitable for instant eating. The culture medium components comprise the following raw materials in parts by weight: 30 parts of perlite, 30 parts of live moss, and 10 parts of marsh soil, water is added in the culture until the water content is 75%-85%. According to the new blueberry product (called M9 for short) suitable for instant eating, which is prepared by the method, fruit granules are large, the weight of single blueberry is 2.9g-3.2g, and fresh blueberries contain 14-15% of sugar and are good in taste. The new blueberry product is suitable for being picked in picking gardens at urban suburbs, and has an extremely high economical value.

Description

The seedling-cultivating method of the blueberry new varieties that a kind of adaptation is eaten raw

Technical field

The present invention relates to blueberry planting technology, relate in particular to the seedling-cultivating method of the blueberry new varieties that a kind of adaptation eats raw.

Background technology

Blueberry is described as " world fruit queen ", and blueberry is being contained lot of anthocyanin, has and delays senility, and strengthens the immunity of human body, the special role of alleviating asthenopia.China mainly produces in Daxing'an Mountainrange and forest zone, the Xiaoxinanlin Mountains especially Central Greater Khingan Mountains, and is all pure wild.Just successfully carried out in recent years domestication's cultivation, taste meta-acid, fruit is less.

Along with improving constantly of people's living standard, city dweller more and more yearns for idyllic life, has gradually occurred harvesting garden, urban fringe suburb.In the picking season, whenever weekend or holiday, harvesting activity is carried out in the harvesting garden that just someone will, have with wife child, relatives and friends in some pacts, have plucked the fashion activity of loosening leisure into city dweller.Yet in blueberry harvesting process, due to existing Blueberry taste meta-acid, short sweetness and fruit are less, do not preponderate in the market of eating raw in harvesting.Pluck sales volume obviously pessimistic.

Summary of the invention

For solving the deficiencies in the prior art, the present invention aims to provide the seedling-cultivating method of the blueberry new varieties that a kind of adaptation eats raw.

The technical solution used in the present invention is:

A seedling-cultivating method for the blueberry new varieties that adaptation is eaten raw, comprises the following steps:

1. the selection of male parent, female parent: select blueberry kind Berkeley as male parent, M7 is as female parent for blueberry kind;

2. group training: get respectively the stem section tissue of M7, the leaf bud tissue of Berkeley is organized cultivation, by induction formation plant again;

3. screening: select the good plant of upgrowth situation to cultivate and wait for cuttage;

4. cuttage: on medium, plant is carried out to cuttage, obtain and adapt to the blueberry new varieties plant of eating raw after 3-6 month.

Medium component in described step 4 comprises according to mass fraction meter:

30 parts of perlites; 30 parts of liver mosses alive; 10 parts of careless beaches soil, adding water, to be adjusted to water content be 75%-85%.

Described M7(bluesouth) cry again blue source, its cultivar origin is:

The vertical university of this product germline Michigan State Usa Chinese. one of hybridization strain that cock professor selects.From the U.S. introduces, by field seed selection for many years and Character Evaluation, therefrom select the improved seeds that are suitable for China Middle-north Area and greenhouse culture in October, 1999.Through molecular biology identification, its female parent is south high clump kind Misity(mist), male parent is not quite clear.

Introduce a fine variety and extension process:

Within 1999, introduce this kind, in company base, carry out the cultivation of planting experimentally in potted plant, open country and greenhouse.2006 start, and in Dalian with field has been carried out in Operation in Dandong Area and greenhouse has carried out tentative cultivation, enter the full bearing period at present.2011, in Jagdaqi, Heilungkiang, plant experimentally successfully.Through too much kind comparison, be defined as the best kind of greenhouse culture, area is planted experimentally over 300 mu in greenhouse at present.

Varietal characteristic:

The height of tree is 2 meters of left and right.Tree vigo(u)r is prosperous and powerful, and tree performance is opened a business.Fruit grain is large, 1.4 grams～2.8 grams of single fruit weights.2.0 grams of mean fruit weights.Fruit look dark blue, fruit powder is medium.Eat fruit sugar content 13.4% raw, acidity pH value 3.53.Thick flavor, greenhouse culture local flavor is splendid.Flesh texture is hard, resistance to accumulating.Be very suitable for eating raw.

Growth characteristics:

Cold temperature amount demand is 800 hours.Early-maturing variety, Liaoning Area greenhouse culture late March starts to pluck.Yielding ability is good, can reach more than 1000 kilograms in every mu of full bearing period.Resistance and growth potential are extremely strong, are the preferred kinds of greenhouse culture.

Cultivation main points:

1, this kind growth potential is strong, amount of growth is large, and output is high, and suitable planting density is 300 plants/acre.

2, high yield period need be pruned the strict output of controlling by severe, guarantees fruit quality.

3, high to nutritional need, growth animated period is prone to de-fertile phenomenon, need carry out the monitoring of the nutrition condition of process of growth, topdresses in time.

Suitable kind of area:

The preferred kind of northern Heilungkiang to the Shandong District greenhouse culture of China.The regional outdoor croppings such as China's Middle-north Area Southern Shandong Province, Anhui, Along North Jiangsu can recommended variety.

The invention has the beneficial effects as follows: the blueberry new varieties that the adaptation obtaining according to the method for the invention is eaten raw (being called for short M9), fruit grain is large, and 2.9 grams～3.2 grams of single fruit weights are eaten fruit sugar content 14-15% raw.Eat mouthfeel raw good.Be applicable to harvesting garden, urban fringe suburb and pluck purposes, there is very high economic worth.

Embodiment

Select blueberry kind Berkeley as male parent, M7 is as female parent for blueberry kind; Get respectively the stem section tissue of M7, the leaf bud tissue of Berkeley is organized cultivation, by induction again, forms plant; Select the good plant of upgrowth situation to cultivate and wait for cuttage; On medium, plant is carried out to cuttage, after 3-6 month, obtain and adapt to the blueberry new varieties plant of eating raw.Described medium component comprises according to mass fraction meter: 30 parts of perlites; 30 parts of liver mosses alive; 10 parts of careless beaches soil, adding water, to be adjusted to water content be 75%-85%.
