Abstract

The invention relates to a seedling method of sweet tamarind container seedlings. Due to the fact that treatment is conducted on a seedling bed, root shearing time is explored, and improvement is conducted on management measures in later period, a root system is effectively prevented from extending out of a container, the growth of the root system in the container is facilitated, the survival rate of sweet tamarind seedling transplanting is greatly increased, and the survival rate of transplanting reaches 99 percent.

Description

A kind of sweet angle container seedling seedling-cultivating method

Technical field

The invention belongs to agricultural technical field of cultivation, be specifically related to sweet angle container seedling seedling-cultivating method, especially in seedling raising process, improve the method for transplanting survival rate.

Background technology

The tropical fruit tree that Tian Jiaoshi China introduces recently, have edible, medicinal, material with and for the multipurpose tree species of afforestation, because it is the system of taproot, fast growth, be easy to pass container bottom when container seedling nursery, during transplanting, root damage is serious, and survival rate is low.

For preventing root system from passing container, utilize the principle that plant " suppresses main root growth, promotes that side root is sprouted ", in the nursery of other plant, have employed different modes and shear root, some shears after vernalization, some is repeatedly sheared in nursery midway, and also some shears before transplanting.Seedling is sheared the impact of seedling growth comparatively large, and needs to increase pregermination procedure, the bad assurance of shear time in seedling raising process, too early, need repeatedly to shear, too late, large to seedling damage, before transplanting, shearing is saved trouble relatively, but maximum to the damage of seedling, has a strong impact on transplanting survival rate.In addition, the root system in container is always injured when seedling being pulled up from seedbed.In a word, the seedling-cultivating method passing container is time-consuming, effort to utilize shearing root to prevent at present, and the growth affecting seedling all in various degree.

Summary of the invention

For solving the problem, the invention provides a kind of sweet angle container seedling seedling-cultivating method, the root system when emerging can be effectively prevent and pass container, facilitate the growth of root system in container, greatly improve the survival rate of sweet angle transplantation of seedlings, make its transplanting survival rate reach 99%.Its technical scheme is:

A kind of sweet angle container seedling seedling-cultivating method, is characterized in that comprising the steps:

(1) seedbed process, at upper berth, seedbed one deck sand, thickness is greater than 10 centimetres.

(2) shearing of root, as the acrial part of seedling 10-20 centimetre longer than container for plant growth height, picks up container for plant growth, by passing eradicating outside container for plant growth from sand, is cut by the root passed outside container.

(3) final-period management measure, increases frequency of watering, and reduce single irrigation amount, every 1-2 days waters a water, is no more than 30 millimeters at every turn, every 3-6 month mobile container for plant growth once.

When cutting root, container for plant growth must be picked up, pull up the root passed outside container for plant growth simultaneously, at upper berth, seedbed one deck sand, conveniently will pass having eradicated outside container for plant growth, reduce the damage to container for plant growth inside root system.

When the acrial part of seedling is than container for plant growth height height 10-20 centimetre, starts to shear the root of seedling, cut by the root passed outside container, is at this moment the best opportunity of shearing, and can reach the top the object suppressed, and also can not cause very macrolesion to seedling.

In order to prevent the main root continued growth after shearing, take corresponding final-period management measure.Increase frequency of watering, reduce single irrigation amount, every 1-2 days waters a water, is no more than 30 millimeters at every turn, keeps the middle and upper part of container for plant growth mesostroma moistening, bottom relatively dry as far as possible, thus suppresses main root long.Every 3-6 month mobile container for plant growth once, the root growth passed outside container is disturbed.

Described " being no more than 30 millimeters " at every turn, the water depth referring to without evaporation, permeate, run off and gather on the water surface.

In order to prevent band soil in sand, preferably select river sand, thickness is greater than 10 centimetres, preferably at 15-20 centimetre.

By above-mentioned steps, root system can be effectively prevent and pass container, facilitate the growth of root system in container, greatly improve the survival rate of sweet angle transplantation of seedlings, make its transplanting survival rate reach 99%.

Embodiment

Below by embodiment, the present invention will be further described.

Select diameter 10 centimetres, the nutritious bag of height 22 centimetres is container for plant growth; Seedbed paving river sand, thickness is 20 centimetres; After planting 50 days, height of seedling 40 centimetres, started to shear root, is cut by the root passed outside bag; In final-period management, adopt sprinkling irrigation, within every two days, water a water, each 30 millimeters, movement in every 4 months once.Height of seedling 80 centimetres after 10 months, bag rate of wearing is 0, transplanting survival rate 100%.

Claims
