Abstract

The invention discloses a degradable test tube root-promotion drought-resistant breeding method, comprising the steps of: 1) firstly preparing a plastic test tube (1), nutrient solution (2), medical cotton (3) and seeds (4); 2) erecting the plastic test tube (1) and adding the nutrient solution (2) which is 5cm away from the mouth of the test tube; 3) stuffing the medical cotton (3) which makes contact with the nutrient solution; 4) adding the seed (4) on the medical cotton (3); and 5) cultivating in a greenhouse or a laboratory and then transplanting into an external tree well when the root length of the plant is 20cm away from the bottom of the plastic test tube (1).

Description

A kind of degradable test tube is urged root drought resisting seedling method

Technical field

The present invention relates to promote the method for plant root growth.

Background technology

In the arid and semi-arid area, Gobi desert desertificated area, soil moisture content become the principal element of the ecological improvement of restriction, rural economic development.In these areas, soil moisture content is low, water table buries deeply, and the plant of conventional method plantation is often dead because of can not get enough moisture, perhaps need water a large amount of water and could become work.The common naked thing of planting often all need cut off main root because of transplanting, and the root system of plant is transplanted the back main root can not absorb not the moisture of deep subsoil again toward the deep subsoil growth yet, finally causes death.Common plant through the seed plantation, early growth period is more small and weak, needs a large amount of moisture, is difficult to growth in arid and semi-arid area and Gobi desert desertificated area, also with death.The seed bed seedling-cultivating method (02125286.6) of invention is liked at temple, Japan mountain; Can overcome above two shortcomings, but cultivate the cost height, and the sapling of cultivating when transplanting root system too shallow; Also damage the root system tip easily, still dead easily in the area growth that some environment are abominable especially.

Summary of the invention

The purpose of this invention is to provide a kind of method that improves plant drought resistance.

The present invention is the short root drought resisting seedling method of test tube, the steps include: that (1) at first is ready to plastic test tube 1, culture fluid 2, medical cotton 3, seed 4; (2) plastic test tube 1 is upright, add culture fluid 2 apart from test tube mouth 5cm; (3) filling in medical cotton 3, medical cotton 3 contacts with culture fluid 2; (4) on medical cotton 3, add seed 4; (5) in the greenhouse or laboratory cultures when the root length of plant reaches apart from plastic test tube 1 bottom 20cm, be transplanted in the outside tree well.

The present invention compares with background technology, and effect is: simple, the easy operation of the short root drought resisting seedling method device of this test tube, strong, the low price of applicability.Through the sapling that this method cultivates out, well developed root system, root system can reach 80cm during transplanting, even can reach 130cm, and not damage of root system.Transplant in a very long time of back, plant is appointed the right passable supply of culture fluid in vitro that obtains.After a period of time, plastic test tube is degraded gradually, and the root system of plant also combines together with soil on every side gradually; When plant has had the root system more than the 80cm, just can absorb the profound underground water of root, made full use of groundwater resources, improved the drought-resistant ability of plant widely, thereby improved plant survival rate, improved the ability that plant is improved environment.

Description of drawings

Fig. 1 is a sowing sketch map of the present invention, and Fig. 2 is the partial enlarged drawing of Fig. 1, and Fig. 3 is that the present invention transplants preceding sketch map, and Fig. 4 is that the present invention transplants the back plastic test tube and degrades gradually, root system of plant and the soil sketch map that combines together, and Fig. 5 is Fig. 4 partial enlarged drawing.

Reference numeral and corresponding name are called: 1. plastic test tube, 2. culture fluid, 3. medical cotton, 4. seed, 5. sapling, 6. main root, 7. lateral root, 8. soil.

Embodiment

Like Fig. 1, shown in Figure 2, in greenhouse or laboratory, establish rack for test tube, plastic test tube 1 is stood on the rack for test tube; In plastic test tube 1, add culture fluid 2 apart from test tube mouth 5cm; Fill in medical cotton 3, medical cotton 3 then and contact, on medical cotton 3, add seed 4 with culture fluid 2.Regulate the temperature and humidity in greenhouse, impel plant establishment to germinate, when the root length of plant reaches apart from plastic test tube 1 bottom 20cm, be transplanted in the outside tree well.If plant leaf growth is too fast during this, then need use some medicines to suppress the plant leaf growth, branches and leaves do not surpass 25cm during plant transplantation.

Plastic test tube 1 degradable, degradation time are 6 months to 1 year; The plastic test tube wall will have certain rigidity, can insert in the preformed hole of soil smoothly when being convenient to transplant; The plastic test tube diameter is 1.5cm～2.0cm; Plastic test tube is long to be 100cm～150cm.

Medical cotton 3 have sterilized, no bacterium, and also ventilative water permeability is good.

The course of work of the present invention is following:

Like Fig. 2～shown in Figure 3, in the hole that sapling has been accomplished fluently together with insertion of plastic test tube, the test tube mouth is positioned at aperture 2cm～3cm once, with surface dust the hole is covered gently to get final product.Like Fig. 4, shown in Figure 5, plastic test tube begins degraded after 1～2 month, the root system of plant along crack that degraded produces or hole contact with on every side soil, finally and soil on every side combine together.

Claims

1. the short root drought resisting seedling method of degradable test tube the steps include:
