Abstract

The invention relates to a protected Sagittaria sagittifolia seedling raising method, which belongs to the technical field of agricultural (vegetable) cultivation and includes: building a level bed in an insulation facility, and making sure that ridges around the bed are higher than the same; spreading a plastic film on the bed top and the ridges to form a water storage tank; filling the water tank with fresh water; pouring selected terminal buds of Sagittaria sagittifolia into the water tank, raking well to lead the terminal buds to densely float in the water, and making sure that each terminal bud is partially immerged in the water while being partially exposed; erecting an arch shed over the level bed, covering the arch shed with one layer or a plurality of layers to achieve thermal insulation and increase; guaranteeing sunlight to guarantee photosynthesis of leaves of seedlings; and when interior temperature of the facility ready for transplanting reaches more than 15 DEG C, picking out the seedlings which are 20-25cm high, separating mutually entangled roots, and transplanting the seedlings. The method is simple and easy, pest and disease damage in seedling period can be prevented effectively, labor and seedling land are reduced, roots of the seedlings are rich, the roots of the seedlings are less apt to break in lifting before transplanting, and the seedlings can quickly recover to grow after transplanting.

Description

The method that a kind of arrowhead facility is grown seedlings

Technical field

The present invention relates to the method that a kind of arrowhead facility is grown seedlings.Belong to agricultural (vegetables) culture technique field.

Background technology

Arrowhead is grown seedlings generally and all earlier to process the bed of growing seedlings with soil, river silt etc., then with the arrowhead terminal bud with in determining deviation insertion soil or the matrix, let its sprout growth.Arrowhead facility cultivation in early spring then selects for use sturdy terminal bud to do kind, grows seedlings with after temperature bottom out in early spring, in time adopting protection, adopts the seedling transplanting method during height of seedling 15-20cm left and right sides, is transplanted to as early as possible in the facilities such as booth, greenhouse.But often carry the germs of a disease in the soil, worm's ovum, grass-seed etc., disease pest and weed possibly appear in seedling stage, influence the arrowhead growth of seedling; Terminal bud intercuts needs the more labour of cost, and cost is higher; After intercutting with a determining deviation, seedbed, 1 mu of ground generally can only supply 10-20 mu field-transplanting, and the land used of growing seedlings is more.

Summary of the invention

Of the present invention in order to solve the deficiency that prior art exists, simple and easy, the high-efficiency method that provide a kind of arrowhead facility to grow seedlings.Method of the present invention belongs to water-fast wet and the characteristics that sturdy terminal bud has more nutrient can supply the seedling early growth, use seedling to transplant as early as possible again of aquatic vegetable to arrowhead, directly adopts water planting to grow seedlings; According to the phototropic characteristics of seedling, terminal bud is laid on the bed of growing seedlings arbitrarily, thick and fast, not only can practice thrift the labour, but also can practice thrift the land used of growing seedlings, be convenient to management, 1 mu of ground institute's seedling raising of growing seedlings can supply 30-50 mu even more field-transplanting.

The technical scheme that the present invention adopted is that the method that a kind of arrowhead facility is grown seedlings comprises and gives step:

(1) in lagging facility, build flat furrow, ridge exceeds the furrow face all around; On furrow face and ridge, lay plastic film, form the tank of a water storage;

(2) in tank, pour into clear water;

(3) the arrowhead terminal bud of selecting and remain is poured in the tank, rake is even, makes that terminal bud is intensive to be swum in the water, all existing part submerged of each terminal bud, has part to surface again;

(4) on flat furrow, set up shed, single or multiple lift covers to reach insulation and heats on the shed;

(5) in seedling raising process, guarantee illumination, ensure that seedling leaves carries out photosynthesis;

(6) when temperature in the facility to be transplanted reaches more than 15 ℃, the seedling of the about 20-25cm of height of seedling is taken out, the root system that separately twines is each other transplanted.

In the above-mentioned steps (2), the about 5cm of water level; And can add a certain amount of bactericide, as press 800-1500 times of concentration and evenly add 50% carbendazol wettable powder.

The present invention adopts simple and easy means such as " plastic film substrate+filling shallow water (but adding of germicide diseases prevention)+close shop arrowhead terminal bud+multilayer cover short long ", reaches arrowhead facility nursery effect efficiently.

Advantage of the present invention and effect are simple and easy to do, can effectively prevent the disease pest and weed in seedling stage, and practice thrift the labour and grow seedlings land used, and the rice shoot root of hair is more, and lifting is difficult for being completely cured before transplanting, and can comparatively fast recover growth after the transplanting.

Description of drawings

Fig. 1 is a photo of laying the arrowhead terminal bud.

Fig. 2 is the photo of arrowhead seedling growth.

Embodiment

(1) January early and middle ten days, in facilities such as booth, greenhouse, build flat furrow, smooth furrow face makes the discrepancy in elevation be no more than 5cm, ridge exceeds the about 10cm of furrow face all around; On the furrow face, lay monoblock (water-tight) plastic film, the edge is not less than the ridge height, forms the tank of a water storage.

(2) pour into clear water, the about 5cm of water level.For preventing that disease from taking place at seedling stage, can add a certain amount of bactericide, as press 800-1500 times of concentration and evenly add 50% carbendazol wettable powder.(pour water in advance and both can detect tank and whether leak, water temperature is raise be beneficial to the arrowhead terminal bud sprout as early as possible)

(3) mid or late January, the arrowhead terminal bud of selecting and remain to be poured in the tank, rake is even, makes that terminal bud is intensive to be swum in the water, all existing part submerged of each terminal bud, has part to surface Fig. 1 again.

(4) on flat furrow, set up shed, the covered with plastic film insulation heats; Lower like ambient temperature, can on shed, add a cover further insulation such as nonwoven and plastic film and heat.

(5) in seedling raising process, cover like multilayer on the shed, should by day nonwoven and the plastic film on upper strata be opened, photosynthetic to guarantee illumination, guarantee seedling leaves.

(6) in facilities such as booth to be transplanted, greenhouse (general individual layer cover) when temperature reaches more than 15 ℃ (at the beginning of general 3 months, the about 20-25cm of height of seedling, Fig. 2), seedling is taken out, the careful root system that separately twines is each other transferred to transplanting in booth, the greenhouse.Rice shoot root of hair of the present invention is more, and lifting is difficult for being completely cured before transplanting, and can comparatively fast recover growth after the transplanting.

Claims

1. method that the arrowhead facility is grown seedlings is characterized in that may further comprise the steps:

(2) in tank, pour into clear water;

2. arrowhead facility seedling-cultivating method according to claim 1 is characterized in that in the step (2) the about 5cm of water level; And interpolation bactericide.

3. arrowhead facility seedling-cultivating method according to claim 2 is characterized in that said bactericide is evenly to add 50% carbendazol wettable powder by 800-1500 times of concentration, or other similar kind bactericide and EPCs.
