Abstract

The invention discloses a method for cultivating Sihong jujube, which belongs to the field of crop cultivation and comprises cutting rootstocks from seedlings, cutting scions, and grafting. The method has the advantages that excellent characteristics of Sihong jujube and wild jujube are fully retained, fruiting is early, yield is high, fruits are big and high in sugar content, and the method is wide in application.

Description

The cultivation method of a kind of Sihong date

Technical field

The present invention relates to a kind of cultivation method of date, concrete is the cultivation method of a kind of Sihong date.

Background technology

The big date fruit in Sihong is oval, 5.7 centimetres in vertical footpath, 5.9 centimetres of transverse diameters, mean fruit weight 50 grams, maximum fruit 107 grams that weigh, fruit is big, and meat is crisp like egg, sweet examine little.

Measure through relevant department's science; New varieties Sihong date contains soluble solid more than 30.5%; Contain protein 2.2%, also contain the indispensable mineral matter elements of human body such as iron, phosphorus, calcium, contain 17 seed amino acids and abundant vitamin of needed by human body simultaneously.In the bright jujube of every hectogram, contain 3000 milligrams of 580 milligrams of vitaminB10 .06 milligrams, 0.04 milligram of vitamin B2, vitamin C (for 76 times of apple), citrins (rutin), also contain vitamin A, vitamin E etc. in addition.The Sihong date has the laudatory title of vitamin pill alive.The Sihong date florescence is long, and the flower amount is extremely many, is the nectar source of high-quality.Detect proof through units concerned, Mel Jujubae is only second to honey of lychee flowers and occupies second.Jujube wood is high-quality hardwood, is the preferred material of engraving, tools and car, ship vitals.Micromicro is used as medicine, and jujube nuclear is the good raw material of producing active carbon.Dogberry can extract essence, and tender leaf also can be processed as health-care tea.The Sihong date also has multiple medicinal health effect, but its leaf, really, the equal people's medicine of flower, skin, root, thorn and timber.Recent study finds that it is unimpeded to contain the maintenance capillary in the jujube fruit, prevents the material rutin that vascular wall fragility increases, and cancer-resisting substance AMP and catechol.This shows that jujube is the good health care good merchantable brand.Popular legend " jujube for a long time food make light of one's life by commiting suicide prolong life " legend of " solar eclipse three jujubes are not aged ", the science reason is arranged.The Sihong date is not only the outstanding person who eats jujube raw, can also be processed into liquor-saturated dates, candied date, sandwich jujube, jujube juice, sweet can etc.

Summary of the invention

It is a kind of simple, convenient that the object of the invention provides, and stock is injured light, and grafting place is prone to healing, Sihong date that survival rate is high and mountain jujube grafting method.

The present invention realizes through following scheme, and the cultivation method of a kind of Sihong date comprises rootstock seedling shearing, the cutting of scion, grafting step, and its method is made up of following steps:

1., behind the autumn mountain jujube seedling fallen leaves, selects disease-free healthy and strong individual plant, cut off all side shoots that anvil is done, plant into big Tanaka, water sufficient water after, cover little bow plastic film, the back grafting use of waiting to germinate;

2., clip gives birth to jujube head branch or two branches of Sihong date then, makes scion, is 40-70% in humidity, temperature be preserve under 4-8 ℃ the condition subsequent use;

3., rootstock seedling is cut off the first half for liftoff about 10 centimetres during grafting; Cortex rip cutting one is about the perpendicular mouth that 15 millimeters deep reach xylem downwards from the rootstock seedling clip, otch upper end cortex with cutting point to both sides strip off gently, is whittled into scion on the horse ear shape inclined-plane that is about 20 millimeters at the side or the back side of scion bud; Again with the prune Lao Pi of both sides, the back side on inclined-plane of knife; Make it to expose phloem,, insert the subcutaneous of stock the inclined-plane of scion xylem towards stock; Make the top, inclined-plane of the scion 2-4 millimeter that shows money or valuables one carries unintentionally, with plastic film tape interface is twined and bandage;

4., after scion is germinateed, long to more than 50 centimetres the time, beat the top heart, bring into use agricultural chemicals, with preventing disease and pest;

5., treat grafting fallen leaves after, can transplant, during transplanting, soil will bury grafting place, perhaps open country is passed the winter, and notices that soil will bury grafting place.

The invention has the beneficial effects as follows, fully keep the good characteristic of Sihong date and mountain jujube, the result early, output is high, fruit is big, sugar content is high, wide adaptability.

Embodiment

Embodiment 1

The cultivation method of a kind of Sihong date comprises rootstock seedling shearing, the cutting of scion, grafting step, and its method is made up of following steps:

1., behind the autumn mountain jujube seedling fallen leaves, select to be grown in the disease-free healthy and strong individual plant on nine li mountains, cut off all side shoots that anvil is done, plant into big Tanaka, water sufficient water after, cover little bow plastic film, the back grafting of waiting to germinate is used;

2., clip gives birth to jujube head branch or two branches of Sihong date then, makes scion, is 40-70% in humidity, temperature be preserve under 4-8 ℃ the condition subsequent use;

3., rootstock seedling is cut off the first half for liftoff about 10 centimetres during grafting; Cortex rip cutting one is about the perpendicular mouth that 15 millimeters deep reach xylem downwards from the rootstock seedling clip, otch upper end cortex with cutting point to both sides strip off gently, is whittled into scion on the horse ear shape inclined-plane that is about 20 millimeters at the side or the back side of scion bud; Again with the prune Lao Pi of both sides, the back side on inclined-plane of knife; Make it to expose phloem,, insert the subcutaneous of stock the inclined-plane of scion xylem towards stock; Make the top, inclined-plane of the scion 2-4 millimeter that shows money or valuables one carries unintentionally, with plastic film tape interface is twined and bandage;

4., after scion is germinateed, long to more than 50 centimetres the time, beat the top heart, bring into use agricultural chemicals, with preventing disease and pest;

The Sihong date that experiment showed, this method grafting has good disease and insect resistance performance, and the rich fruit phase is short, on average increases production 30%.
