Abstract

The invention relates to a method for cultivating winter-jujube saplings. The method includes steps of (1), acquiring slim stalks of the winter-jujube saplings for standby application; (2), soaking the collected winter-jujube saplings in rooting liquid; (3), carrying out cuttage on the slim stalks of the winter-jujube saplings on sand seedbeds in greenhouses after the slim stalks of the winter-jujube saplings are soaked in the rooting liquid; (4), applying phosphate fertilizers on the winter-jujube saplings in four or five days after cuttage is carried out on the slim stalks of the winter-jujube saplings, and then spraying phosphate fertilizers on the winter-jujube saplings once every seven days; (5), carrying out cuttage grafting on the winter-jujube saplings onto stems of wild jujube trees outdoors, and manufacturing V-shaped notches on the stems of the wild jujube trees; (6), fully painting latex on grafted stems of the wild jujube trees and wrapping the grafted stems of the wild jujube trees by the aid of plastic tapes so as to completely cultivate the winter-jujube saplings. The method has the advantages that problems of low survival rate of existing winter-jujube saplings during cultivation and difficulty in enabling the existing winter-jujube saplings to live through winters can be solved; the winter-jujube saplings can be cultivated through the winter by the aid of a cuttage process, are high in survival rate and disease resistance and can quickly grow.

Description

A kind of cultivating method of winter jujube tree seedling

Technical field

The invention belongs to field of forestry, relate to the culture technology of sapling, especially a kind of cultivating method of winter jujube tree seedling.

Background technology

Winter jujube is the late-maturing Zizyphus jujuba Mill kind of high-quality, and fruit exactly likes griggles, and the thin meat of skin is crisp, the dense sweet micro-acid of taste, nutritious, is especially rich in vitamin C, and every 100g pulp, containing vitamin C 381mg, has the title of " vitamin pill of living " and " kings of all kinds of fruits "; Winter jujube is also rich in cyclic adenosine monophosphate, has very high health value, therefore enjoys people to like.

From the end of the nineties in last century, winter jujube in China shaping and development upsurge, national winter jujube area under cultivation in 2006 more than 150 ten thousand mu.But it is very few that the peasant in China's new development winter jujube producing region grasps winter jujube culture technique knowledge, and culture technique is seriously deficient, cause winter jujube to exist on producing serious to yield poorly, the problem such as poor quality, not even result.Therefore, the culture technique solving winter jujube tree seedling has become the task of top priority ensureing that China's winter jujube industry develops in a healthy way.

Summary of the invention

The object of the invention is to overcome prior art deficiency, the cultivating method of the winter jujube tree seedling that a kind of survival rate is high, resistance against diseases is strong is provided.

The technical scheme that the present invention realizes object employing is:

A cultivating method for winter jujube tree seedling, step is:

(1), before and after November after autumn, gather the thin stem stalk of winter jujube tree seedling, the footpath of this stem stalk is slightly 3-4mm, and bar height is 20-30mm, gathers for subsequent use;

(2) soaked in taking root liquid by the winter jujube tree seedling of collection, soak time is 1-2 hour, and taking root liquid requires to adopt the taking root liquid meeting national standard;

By soaked taking root liquid the sand seedbed of winter jujube tree seedling thin stem stalk cuttage in greenhouse on, the sand in sand seedbed is 1:2 with the ratio of soil, and cuttage spacing is 30-40mm, and the temperature in greenhouse remains on about 15-20 DEG C;

(4) cuttage is after four, five days, executes phosphate fertilizer, sprays once afterwards, be as the criterion with winter jujube tree seedling thin stem stalk surface wettability every 7 days;

(5) the early March in spring, gets final product lifting, and open air is plugged on the stem of wild jujube tree, and the stem of wild jujube tree makes v-notch, and the insertion portion of winter jujube tree seedling will go deep into dry more than the 10mm of spina date stem;

(6) fill latex at the grafting stem position of wild jujube tree, and adopt plastic tape to superscribe, namely complete the cultivation of winter jujube tree seedling.

And the grafting stem diameter of described wild jujube tree is not more than 20mm.

Advantage of the present invention and good effect are:

Instant invention overcomes existing winter jujube tree seedling survival rate in cultivation low and be difficult to the problem of surviving the winter, adopt cottage method to be survived the winter by winter jujube tree seedling cultivations, not only high, the resistance against diseases of survival rate by force, and also improve winter jujube tree seedling and grow problem rapidly.

Embodiment:

Below in conjunction with specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.

A cultivating method for winter jujube tree seedling, step is:

(1), before and after November after autumn, gather the thin stem stalk of winter jujube tree seedling, the footpath of this stem stalk is slightly 3-4mm, and bar height is 20-30mm, gathers for subsequent use;

(2) soaked in taking root liquid by the winter jujube tree seedling of collection, soak time is 1-2 hour, and taking root liquid requires to adopt the taking root liquid meeting national standard;

By soaked taking root liquid the sand seedbed of winter jujube tree seedling thin stem stalk cuttage in greenhouse on, the sand in sand seedbed is 1:2 with the ratio of soil, and cuttage spacing is 30-40mm, and the temperature in greenhouse remains on about 15-20 DEG C;

(4) cuttage is after four, five days, executes phosphate fertilizer, sprays once afterwards, be as the criterion with winter jujube tree seedling thin stem stalk surface wettability every 7 days;

(5) the early March in spring, gets final product lifting, and open air is plugged on the stem of wild jujube tree, and the stem of wild jujube tree makes v-notch, and the insertion portion of winter jujube tree seedling will go deep into dry more than the 10mm of spina date stem; It should be noted that the grafting stem diameter that wild jujube is set is not more than 20mm, best with 15mm;

(6) fill latex at the grafting stem position of wild jujube tree, and adopt plastic tape to superscribe, namely complete the cultivation of winter jujube tree seedling.

By the inspection after transplanting, adopt the winter jujube tree seedling of the present patent application cuttage, survival rate more than 95%, healthy growth, resistance against diseases is strong, and the April can go out three leaf buds, and the June can grow tall 10-15cm.
