Description

The moistening seedling-cultivating method in a kind of cigarette district

Technical field

The present invention relates to agricultural technology field, be specifically related to a kind of respond well moistening seedling-cultivating method in cigarette district.

Background technology

The moistening seedling growing process in cigarette district inherits the advantage of floating seedlings technology and tray seedling growth technology two kinds of seedling raising mannerses, be not only adopt artificial matrices, reduce garden, Weed infestation to greatest extent, and nursery affects nutrient solution and substrate temperature because temperature is low season in early spring to make up floating seedlings technology, and then affecting the deficiency of the sprouting of cigarette kind and growth of seedling, seedling cost is lower than floating seedlings technology in addition.

Current moistening seedling growing process also exists following problem: one is that water pond adds water frequently, takes a lot of work consuming time; Two is after planting cause emerging uneven without covering matrix; Three is that to be located in mountain area vega distant, and tobacco grower does not accept scene and lifts seedlings.

Summary of the invention

For above-mentioned situation, the object of this invention is to provide the moistening seedling-cultivating method in a kind of cigarette district, strong sprout, rate promoted, and seedling uniformity, total emergence rate and operating efficiency all increase.

Technical scheme of the present invention is as follows: the moistening seedling-cultivating method in a kind of cigarette district, comprises the following steps:

1, the preparation in nursery place

Build concrete seedling pond, seedling pond specification 900 × 230 × 5(mm), seedling dish specification 56 × 28 × 5(mm), 128 caves, 128, seedling dish is joined in each seedling pond, stays pavement 300(mm between seedling pond);

2, medium in tray

Stalk, the peat composed of rotten mosses, expanded perlite are obtained matrix according to 1:1:1 proportions, and matrix loads seedling dish after mixing water mixing, and firmly pauses to end, strikes off with plank, to guarantee that sabot is solid, nothing leaks cave;

3, seeding and growing seedling

Utilize sower to sow, the sowing time is-10 days on the 5th annual March, watches in seedling disk point whether having cigarette kind in seeding process, in order to avoid broadcast leakage, uniform for step 2 mixture butt matter is sieved simultaneously and directly covers seedling dish, make seed cladding thickness about 1mm;

Seedling pool inner water height 3mm, proportioning tobacco leaf seedling-raising special fertilizer (production of Jiangxi three You Tianhui nursery Materials Co., Ltd), nitrogen, phosphorus, potassium content 18:10:15, interior calcic, iron, manganese, copper, molybdenum, magnesium, zinc, boron trace element, the quality of water is 1000 times of special fertilizer;

4, seeding stage management

Seeding stage temperature controls below 28 DEG C, humidity is not to occur in canopy that steam is as the criterion, ensure more than 8h light application time every day, when the cigarette seedling of 80%-85% grow the 5th leaf namely enter the little cross phase time, carry out thinning, seedling one strain is stayed in every cave, strain size is stayed to be consistent, control temperature is no more than 32 DEG C afterwards, and dry beginning of seedling hair updo adds water, and according to step 3 proportioning special fertilizer;

5, leaf-cutting

When cigarette seedling all envelope dish start leaf-cutting after namely cannot see seedling dish, leaf-cutting is highly distance cigarette seedling core leaf about 2-2.5cm, cuts second time, takes root, leaf portion in conjunction with water supplementing method afterwards, to reach the effect of alternation of wetting and drying, promote cigarette root growth after 7 ~ 10 days;

6, plant protection management

Based on fungal disease, aphid pest control, on March about 20 alternately sprayed mancozeb, alkene copper sulphate, amino-oligosaccharide, and interval time is one week, sprays proportioning Imidacloprid at every turn;

7, transplant

Cigarette seedling reaches seedling standard, just can transplant when weather is applicable to.

Preferably, when described matrix is sieved, the aperture of sieve is 2 ~ 3mm, and to remove intramatrical bulky grain, bulky grain covers not tight too much, and effect is bad.

Beneficial effect of the present invention

1, water pond adds water and changes into after Miao Chi adds water, and unifiedly to add water, join fertilizer, the 2 people workload of 3 days before, present 1 people completes for 1 day, and operating efficiency improves 6 times.

2, after planting cover matrix, cigarette seedling is emerged unanimously, and strong sprout, rate promoted, and planting percent brings up to more than 95% by 80%.

3, after seedling is sent in unification, ensure cigarette district vega transplanting seedling, cigarette seedling sends, welding angle steel shelf, the spacing 120mm of level, installs iron sheet additional, 10 layers, each shelf, and 2 shelfs joined by each agricultural vehicle, single send seedling 400 to coil, and send seedling through unified, tobacco grower's acceptance, satisfaction improve greatly.

4, tobacco root system is flourishing, after transplanting, cigarette seedling also seedling stage without or 1 ~ 3 day.

7, transplant

Cigarette seedling reaches seedling standard, just can transplant when weather is applicable to.

In order to verify the nursery effect of the inventive method further, contrast with traditional moistening seedling-cultivating method, result is as following table:

Seedling-cultivating method	Emerge the cycle (my god)	Emergence rate	Height of seedling (cm)	Seedling dry weight (g)	Root/shoot ratio	Planting percent
							This method	14	92.1%	9.2	0.47	0.28	96%
The moistening nursery of tradition	22	89.3%	8.5	0.39	0.20	80%

Experimentally result, this method speed of emergence and tobacco seedling growth speed are all faster than the moistening nursery of routine, and emergence rate significantly improves, and strong sprout, rate also increased, well developed root system.
