Brassica rapa L is called Shanghai Chinese cabbage, SUZHOUQING(sic), green river dish, green ginger dish, small Chinese bush cherry dish, green stalk Chinese cabbage, green river Chinese cabbage, oil
Dish, soupspoon dish are the most common varieties of Brassica campestris in East China of one band of Shanghai.Since Shanghai leafiness lacks, stem is more, and dish stem is in vain
Picture PERICARPIUM LAGENARIAE, therefore, Brassica rapa L also has that be called wooden dipper white.The characteristics of Brassica rapa L, is that long " open and aboveboard ", each
Piece leaf be all it is dark green, in growth period be completed the photosynthesis of chlorophyll per a piece of leaf.
In recent years, late into the night stream cultivation technique gradually starts to promote, and Brassica rapa L depth liquid stream solution culture facilities cultivation technique is
One from nursery, field planting, daily management, the prevention and control of plant diseases, pest control, nutrient solution control, in due course harvest etc. links standardization, fining
New technology reduces pest and disease damage, reduces artificial and other effects obvious, be for improving yield
Since Brassica rapa L is liked to cool, subzero -3~20 or so, in the case where illumination is sufficient under growth conditions, can get over safely
Winter, therefore Brassica rapa L whole year can be made to plant, but be based on the prior art using artificial method for planting, that is, late into the night stream cultivation technique
Development bottleneck, the crop cycle of Brassica rapa L, Later growth was still too long generally in 30d or so, in particular with China travel
The development of industry, hotel, restaurant increase the requirement for special procuring vegetables, and there is an urgent need to organize production and supply, and the production cycle is longer
Just hinder the timeliness of vegetable supply and the benign development of industrialization.
Meanwhile the particularity based on the training of late into the night flowing water, it is than more serious for Brassica rapa L that downy mildew etc., which propagates venereal disease,
Disease, the underproduction of large area is be easy to cause, for deep liquid stream water planting planting vegetable, with the flowing of nutrient solution
The propagation of bacterial parasite is very fast, and discoveries is waited to post-process, and often has resulted in greater loss, and current technology can not also provide one
Kind reaches the effective ways that prevention late into the night flowing water trains vegetable downy mildew by comprehensive treatment.
Water planting Brassica rapa L Cultivate administration can not refine and technology barrier the reason of, plantation on influenced by soil environment
And it is easy to appear that uneven emergence, growing way are different, appearance is poor, mouthfeel is bad as caused by the uncertainty in planting process
Situation is more common.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of Brassica rapa L depth liquid stream water planting cultural method, following to solve
Technical problem:
1, in the prior art, Brassica rapa L growth cycle is generally at 35 days or so, it is longest may be to after 40 days, this is for a large amount of
Industrialized planting for, growth cycle is too long, cause plantation underproduce, in particular with the development of China's tourist industry, or
Person's particular time hotel, restaurant increase the requirement for special procuring vegetables, and there is an urgent need to organize production and supply, and the production cycle is longer
Just hinder the timeliness of vegetable supply and the benign development of industrialization.
2, the prior art plants Brassica rapa L, and the ventilative water-retaining property of the planting matrix of use is poor, and adhesive is poor, into the water
It is easily loose, low seedling survival rate is caused, the inconsistent of growth cycle is be easy to cause after filling the gaps with seedlings, it is different to ultimately cause growing way, quality
Different, product control is poor.
3, using routine techniques industrialized planting Brassica rapa L, content of chlorophyll b is lower, and photosynthesis is poor, causes organic
Soluble sugar content is low, causes mouthfeel poor.
4, it is more serious disease for Brassica rapa L that downy mildew etc., which propagates venereal disease, be easy to cause subtracting for large area
It produces, for deep liquid stream water planting planting vegetable, as the propagation of the flowing bacterial parasite of nutrient solution is very fast, waits hair
It now post-processes, often has resulted in greater loss；Prevention late into the night flowing water training is reached by comprehensive treatment there is presently a need to find a kind of
The effective ways of vegetable downy mildew.
5, during using routine techniques industrialized planting Brassica rapa L, due to the frequent continuous cropping of same vegetables, easily cause
Soil continuous cropping obstacle, such as salination, acidification, soil hardening；Simultaneously because planting process applies the farmyard manure of night soil, barnyard manure, because
And to the pollution of vegetables and soil-borne disease etc. a series of problem occurs for helminth such as nematode, germ.
6, deep using routine techniques plantation Brassica rapa L, there is more pest and disease damage big, weeds are more, herbicide weeding need to be used,
Vegetable pesticide residue is more, and pollutes to soil, river etc., can not truly produce non-harmful green vegetable
Dish.
7, since prior art plantation Brassica rapa L process is uncontrollable, it can not accomplish standardization and fine-grained management, in soil
In the fields operating process such as farming, fertilising, weeding, prevention and control of plant diseases, pest control, labor intensity is larger.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that:
A kind of Brassica rapa L depth liquid stream water planting cultural method, including following specific steps:
1, nursery
(1) planting matrix prepares: using with the graceful black mud charcoal of import Peter Krass as matrix (complying with standard NY525), humidity 20-50%；
This model peat is breathed freely good water-retaining property, full of nutrition, and adhesive is good, is not easy into the water loose, in moisture adjustment, is fitted
When absorption enzyme solutions, can not only guarantee the basic supply of the nutrition of Brassica rapa L, can also improve to greatest extent nursery at
Motility rate finally makes Brassica rapa L growing way consistent, and product control is preferable.
(2) briquetting: the peat for using seedling culturing machine that black mud charcoal is pressed into length and width as 7-12cm, wherein length and width 9*9cm is left
Right preferably thickness is preferable in 2-5cm, and field planting process is more convenient, quick；Water content, peat humidity are adjusted when mo(u)lded peat block
It is too high or too low to be all not easy blocking, firmly clench that not dissipate the water content that is advisable be about 50-70% to pick up peat with hand；It can also side pressure
Side tune takes Yu Shouzhong is not loosely indeformable to be advisable with pressed peat, and amount of water regards season and initial peat water content is fixed, in the winter
The water content of autumn general mo(u)lded peat 55-60% it, preferably；Summer water content is slightly higher, is between control water content 60-70%
Preferably.
When during peat briquetting, it is preferred to use enzyme solutions adjust water content, and one side nursery stage is that plant is raw
The critical period of production can provide preferably growth base to the adjusting of Primary Root System when nursery for the early growth period of Brassica rapa L
Plinth keeps nursery healthy and strong, and bud ratio is high, improves strain immunity；Secondly, nutriment main source is black mud in nursery stage
Charcoal, due to difference of black mud charcoal attenuation degree etc., black mud charcoal unbalanced nutrition, plant absorption is not very completely, to make
At nursery stage nutritional deficiency；In addition, containing phytic acid-metal ion complex in black mud carbon block, especially to the network of potassium ion
It closes, influences absorption of the plant to potassium element ingredient, the photosynthesis after influencing field planting extends growth cycle.
The enzyme solutions of use mainly include the aqueous solution of phytase, hemicellulase, cellulase；The phytase activity
For 1~50,000 u/g；5~100,000 u/g of hemicellulase enzyme activity；The cellulose enzyme activity is 1~20,000 u/g；Wherein enzyme is molten
In liquid, phytic acid enzyme concentration is 3~5g/L；The concentration of hemicellulase is 3~5 g/L；The concentration of cellulase is 5-10g/L.
Since hemicellulose level is more in peat, hemicellulose enzyme activity is slightly high；And phytase activity is preferred
20000 u/g enzyme activity, 4 g/L of concentration can meet the processing work of black mud carbon block of the present invention；Since cellulase hydrolysis difficulty is opposite
It is larger, therefore select cellulase concentration in 5-10 g/L, preferably 10g/L, it can reach optimal desired effect.
Wherein, the main function of phytase is to decompose the excessive phytic acid metal ion complex in peat, makes mud
Mineral nutrition ingredient in carbon block sufficiently discharges, and the nutrition of the seed after supply field planting improves photosynthesis；Especially black mud charcoal
In the potassium element that contains be complexed, and the absorption of potassium element directly influences the photosynthesis of Brassica rapa L, especially in northerner
During work chamber planting, in the case that intensity of illumination is inadequate, the effect of potassium element is more significant, and the increase of potassium element can be significant
Raising Brassica rapa L chlorophyll content, reduce growth cycle.
Cellulase, hemicellulase main function be as cellulose undecomposed in active ingredient breaks down peat
And hemicellulose, make hemicellulose and cellulose decomposition part monosaccharide, and at this point, due to the seed of germination not can be carried out it is photosynthetic
Effect, monosaccharide have not been only supplied matter and energy required for germination primary growth, have made the Brassica rapa L emergence rate of nursery stage
Simultaneously, extra sugar can store height, increase the mouthfeel plumpness of Brassica rapa L.
(3) it has enough to meet the need: the black mud charcoal suppressed being had enough to meet the need into device with peat and is put in nursery garden.
(4) dibbling: seed is put in black mud charcoal hole, determines that every block of peat is broadcast depending on various percentages of seedgermination and planting density
Kind quantity；Under normal circumstances, it is adapted with peat, dibbling density is that 5-15/peat is preferable, preferably 10/peat
The dibbling density of block or so is best, it is ensured that the shortening of Brassica rapa L growth cycle takes into account the raising of yield.
(5) it adds overburden soil: in order to keep the moisture and temperature in peat, by not plus the black mud charcoal of water is rubbed broken, not having
Larger bulk is advisable, and for uniform fold on the black mud charcoal after dibbling, thickness is excessively thin to cover seed between 0.5-1cm
Lid, blocked up to may cause seed because anoxic germination percentage is low or do not germinate, main function is just right moisturizing, moisture absorption, guarantor
Temperature.After having added blinding, the black mud charcoal in nursery is covered with zinc-aluminium reflectance coating, further prevents the loss and temperature of moisture
It reduces, to improve Sprouting rate and bud ratio.
, field planting
(1) prepare before field planting: injecting nutrient solution in water planting bed, making the nutrient solution water level in water planting bed is 4cm or so, floating to guarantee
Plate conveniently moving can harvest on water planting bed, while guarantee that the Brassica rapa L root system of later period field planting has sufficient growing space.
(2) sprouting stage water management: it is advisable with moistening peat, temperature is conducive to seed fast germination at 15-28 DEG C.Once in a while
Some seeds do not germinate unearthed, and peat moisture is not easy excessive at this time, if peat moisture is excessively dry, water content is less than
When 30%, water mist sprinkling is carried out using sprayer；Not easy-to-use larger water pours, and flood, which can not only go out seed also, will cause kind
Son can not germinate rotten.
(3) take off film: the Brassica rapa L germinating time after nursery is 3-5 days, also slightly has difference depending on season difference and plantation batch.
It is opened as early as possible after seed germination by reflectance coating is incremental, can be opened in dusk on day 2 or morning under dim light, it is best
The case where opening in the morning, avoid the occurrence of seedling excessive growth before 9 points；Should not at noon high temperature when take off film, just taken off film and be a few days ago not easy
There is intense light irradiation, answered incremental；It avoids the tender seedling just to have sprouted from seeing that strong light can wilt, answers incremental adaptation illumination.
(4) field planting confirmation: growing to 4 leaf, 1 core or so to Brassica rapa L budding can unify to be colonized.Guarantee at this time before transplant planting
Brassica rapa L at least three hour after nursery does not water, in order to avoid peat is loose, falls off.And it is main to be colonized initial stage its nutrition supply
It is that and if peat falls off, the deficiency of this plant of nutrition will be caused, ultimately cause growing way deficiency, influence appearance from peat
Consistency.
(5) transplant planting: the nutrient solution water level in confirmation water planting bed is 4cm or so, and kickboard is placed on water planting bed, Shanghai
Green transplant planting density is at least every one, 3 hole, guarantees that transplanting Brassica rapa L black mud charcoal contacts nutrient solution.Guaranteed after transplanting field planting
Water planting bed kickboard does not have vacancy, and water planting bed side nutrient solution is covered comprehensively by kickboard, is protected from light, and reduces nutrient solution evaporation, prevents from seeking
Nutrient solution variable density is too fast.
, daily management
(1) environmental management:
After field planting during slow seedling, room temperature on daytime is kept for 20 DEG C~30 DEG C, and night room temperature is kept for 13 DEG C~20 DEG C.
After slow seedling, daytime, room temperature may be configured as 15~28 DEG C；The control of night room temperature is 10~18 DEG C.
Ambient temperature highest must not be higher than 32 DEG C in entire growth cycle, while can switch in time skylight according to ambient temperature
Cascade and sunshade net carry out adjusting appropriate to temperature.
(2) nutrient solution control management:
If root system is whole for a long time in a liquid, rotting for root system is easily caused, therefore, the best 4cm of nutrient solution water level is simultaneously
Fluid infusion is carried out when liquid level drops to 1-2cm, is kept moving in turn for nutrition liquid level supplement, is conducive to the health of root system of plant.
The general conductive capability that solution total salinity is indicated with conductivity (EC), can reflect nutrient solution total salt concentration, quasi-
True control is conducive to the Precise control management of deep liquid stream water.
The electrical conductivity control of the total nutrient solution of the present invention is preferable in 2~3mS/cm, and it is best to be preferably controlled in 2.5~3mS/cm,
When being lower than this value, solid fertilizer or pre-configured mother liquor should be just supplemented into nutrient solution.
The pH value of nutrient solution is usually indicated with pH value.When solution is in neutrality, then the H+ and OH- phase in solution
Deng pH value at this time is 7.0；When OH- dominance, pH > 7.0, solution alkaline；When H+ dominance, pH < 7.0, solution is in acid
Property.The Brassica rapa L ciltivating process that the present invention uses, the root system for controlling plant are controlled in pH value in 5.5-6.5 range in nutrient solution
It is possible, but under the conditions of 5.6~5.8 faintly acid nutrient solution, Brassica rapa L growth is best under the pH value.PH is too high or too low
Root system can be damaged, the absorption to nutrient is unfavorable for.The method of adjustment pH value is to go to neutralize with acid, alkali.Acid used is phosphorus
Acid or nitric acid or sulfuric acid, preferably phosphoric acid or nitric acid, sulphuric acid cost is lower but danger coefficient is too high, inconvenient；Alkali is generally common
It is potassium hydroxide.
The cultural method for the Brassica rapa L that the present invention uses, the nutrient solution of use include preceding liquid and rear liquid；The preceding liquid is main
For nutriment needed for Brassica rapa L early period (after field planting first 10 days) fast-growth, root system fast-growing；Liquid is mainly used for after described
After field planting 10 days, the nutriment of Brassica rapa L appearance, weight, photosynthesis promotion etc., according to Brassica rapa L in different growths
Phase stresses different growth elements, is more advantageous to the yield for improving Brassica rapa L, shortens growth cycle.
The preceding liquid includes:
1000-2000 parts of potassium nitrate；50-150 parts of manganese sulfate；5-15 parts of borax；5-10 parts of copper sulphate；10-30 parts of zinc sulfate；Molybdenum
Sour sodium 0.5-1.5 parts；1000-2000 parts of calcium ammonium nitrate；20-40 parts of EDDHA；0-12 parts of amino acid 1；
Liquid includes: 3000-4000 parts of potassium nitrate after described；1000-1200 parts of potassium dihydrogen phosphate；100-200 parts of calcium nitrate；Sulfuric acid
50-150 parts of manganese；3-6 parts of borax；1-2 parts of copper sulphate；3-6 parts of zinc sulfate；0.5-1.5 parts of sodium molybdate.
First 10 days after field planting, rotting for root system is prevented, therefore more dissolved oxygens are needed in nutrient solution, at this point, changing
Liquid circulation time is 20~30min/ times；It is colonized later period (after 10 days), it is more 40~50min/ times variable to change liquid circulation time.
(3) plant pest management:
Plant manages the phase, it is proposed that uses following control method, can reach the effect of fast preventing, Drug level is lower, and pesticide is residual
