Description
Technical field
The present invention relates to agriculture fields, and in particular to a kind of vegetable category crop sowing in the field method.
Background technology
Existing sowing in the field technology is in general vegetable category crop (such as watermelon, muskmelon, cucumber, wax gourd, pumpkin and beans
Deng) in it is very universal, usually after big Tanaka completes site preparation, fertilising (or dispenser, overlay film), in growth belt, spacing in the rows is direct according to plan
A quantity of seeds (or bud) is sowed in soil, after rice shoot is unearthed, carries out thinning and enhancement of field management by stages and in groups.
The cultivation crops for rotation of general vegetable category crop (such as watermelon, muskmelon, cucumber, wax gourd, pumpkin and beans) are more, domestic and international crop field
Planting Patterns are commonly used in cultivation, but use nursery (when day temperature >=33 DEG C and night temperature >=25 DEG C) under summer or hot weather
Transplanting, the easy excessive growth of rice shoot, management difficulty is big, it is difficult to nurturing staff, easily occur after transplant crop field survival rate is low, turn green slowly, seedling
Phenomena such as gesture is weak.As crop characteristic and crop field are provided with live streaming condition, generally use sowing in the field at this time.
It as the saying goes " the good half of seedling is received "." one broadcast full stand, seedlings are uniform and strong " is the key that direct sowing culture and difficult point, directly affects
To crop yield and benefit.Soil hardening, poor air permeability are met when live streaming, soil moisture content is laid particular stress on or deficiency, soil pest and disease damage are apparent,
Then emergence rate is low or even if emergence seedling gesture is weak, it is slow to grow；If after planting meeting the weather such as unfavorable high temperature, arid or excessive precipitation
When, then it is easy to happen poor emergence, dead seedling, weak seedling and slow seedling problem.It is that live streaming soil cannot to cause the basic reason of this kind of phenomenon
The growth conditions such as suitable moisture, air and nutrition are provided for seed germination and seedling early growth, so as to cause rice shoot root growth
Impaired development influences normal growth in turn.
Be broadcast live seedling root system it is undeveloped, be existing sowing in the field technology in general vegetable category by disease pest infringement, growth retardation
The most basic reason that crop (such as watermelon, muskmelon, cucumber, wax gourd, pumpkin and beans) seedling stage goes wrong, to largely effect on
The growth in crop later stage leads to underproduction 30-50% or even 70% or total crop failure.
Invention content
To solve the above problems, the present invention provides a kind of vegetable category crop sowing in the field method, it can reliable and stable formation
One broadcasts full stand and seedlings are uniform and strong, facilitates strong sprout early to send out, enhances crop resistance, reaches increasing both production and income.
To achieve the above object, the technical solution that the present invention takes is：
A kind of vegetable category crop sowing in the field method, includes the following steps：
S1, site preparation and fertilization
The selection that field is carried out according to the type of crop, kind, planting density and mode requirement first ploughs deeply soil whole thin

Amount is uniformly poured to spoon to each sowing cave states mixing liquid medicine, ensures substrate soil water content 70% in cave.Soil in cave is such as sowed to contain
Water is higher, then should lack and pour liquid medicine；It is relatively low such as to sow soil moisture content in cave, then should pour liquid medicine more.
S55, vernalization sowing
In order to ensure emergence rate, seed is saved, vernalization sowing can be used.Seed hot water disinfection is carried out with 55 DEG C of water, it is natural
Soak seed 3-4h again after cooling, after pulling the clean drying of seed clear water out, sets 30-35 DEG C of constant temperature vernalization, general 24-30h, the long 0.3- of bud
0.5cm can be sowed.As using 40% formalin, 100 times of seed soaking 1h disinfections, effect is more preferable, but has to clear for seed disinfection
Water rinses 4-5 times repeatedly, prevents residual from causing poisoning.Ready bud carefulness is lain against into substrate soil surface in each sowing cave
Center, by 1-2-1-2 grain numbers successively to every bunch planting kind.
S56, earthing
Get fine crushing soil (most handy paddy soils) of the sterile no worm (ovum) without careless (seed) ready in advance, adjustment soil moisture content exists
30-40%, as blinding after planting.It dampings off for prevention seedling stage or damping-off is done harm to, it, can be uniform by 1m3 blindings when preparing blinding
It is mixed into 500g80% carbendazol wettable powders.It is covered in sowing cave, is allowed to the blinding carefulness that will be got ready after finishing kind
Completely, seed (bud), thickness 1.5cm are uniformly covered.
S6, seedling management
It broadcasts latter general 3 days and emerges, 5 days neat seedlings.General 95% or more emergence rate, cave emergence rate is up to 98% or more.Emergence
The pre- insect-pest of emphasis afterwards, can the morning and evening of melon seedling cotyledon open and flat phase take advantage of temperature it is low when spray 1.8% abamectin emulsifiable concentrate 2000 times 1
It is secondary.Relatively weak one plant is removed to double seedlings cave in 1 heart stage of 2 leaf of melon seedling, ensures there is one plant of strong sprout as possible per cave, at this time seedling
98% or more rate, strong sprout rate is up to 90% or more.It is fast to the field that seedling stage growing way is weaker, 3000 times of 0.01% brassin lactones can be sprayed
With amino acid foliage fertilizer mixed liquor 1-2 times, also to promoting bud differentiation, improving that melon seedling is heat-resisting and disease resistance is advantageous.
S7, training reason are climing
Using three climing pruning methods.Middle fruit type kind is pruned using 1 main stem, 2 lateral bine；Small fruit type kind is using the 3 climing trainings of son
(staying 4 leaf pinching when i.e. melon seedling is grown to 4-5 leaves wholeheartedly, it is climing to select and remain 3 healthy and strong sons later).When managing climing, middle fruit type kind owns
Main stem is placed on compartment face side, and two lateral bines are placed on the other side；One of small fruit type kind climing compared with weakon to be placed on side, another two strip
It is climing to be placed on the other side.And it is climing that all melons are uniformly put on the face of compartment.Before sitting melon stayed melon it is climing on melon wooden fork all to destroy, such as
Growing way is excessively prosperous, also to continue to prune sometimes after sitting melon, and principle is to maintain the climing ventilation and penetrating light of melon, and growth is steady, and nutrition is balanced.
Melon is stayed in S8 pollinations
Bloom bear fruit phase temperature it is higher when, insect activity is few, need using artificial supplementary pollination improve fruit-setting rate.When pollination
Between carried out in morning 7-9, first melon selects the 2nd or 3 female flowers to pollinate, and the pollination of middle fruit type kind main stem is beared fruit.When watermelon is long
Fruit thinning is carried out when to egg size, middle every plant of fruit type kind stays 1 fruit；Every plant of small fruit type kind stays 2 fruits.It should be noted that reservation when fruit thinning
Rounding fruit is dredged and removes disease fruit, weak fruit, malformed fruit.Second batch melon can be beared fruit naturally after the 1st batch of melon is beared fruit 25 days.
S9 fertilizer and water managements
It imposes soluble quick-acting fertilizer on demand using trickle irrigation or pours water.Seedling gesture stalwartness, seedling stage, which does not apply generally, stretches climing fertilizer；Seedling gesture
Climing fertilizer is stretched in suitably imposing for difference.When first watermelon is grown to fist size, swelling melon fertilizer is imposed.Generally 5-8kg high is applied per acre
The low-phosphorous dissolved fertilizer of nitrogen in potassium divides 2-3 times, carries out from less to more, by trickle irrigation.After the harvesting of first melon, in second batch melon
Fruit expanding period will equally impose swelling melon fertilizer.Fertilization time in the afternoon 3 when after, when high temperature to be deferred at dusk 6 when or so preferably.For
Adjusting plant strain growth, to improve fruit-setting rate, volume increase sweetened, coordinates the prevention and control of plant diseases, pest control, since seedling stage in watermelon entire breeding time
Between to spray 3-4 amino acid pattern foliar fertilizer,.
S10 insect pest preventing and controlling
Greenhouse summer and autumn cultivation, the generation such as aphid, thrips, aleyrodid, pathogenicity test, night pretty young woman is heavier, can hang yellow, backboard trapping；
The preventions such as pymetrozine, Diacloden, Biphenthrin, indoxacarb, Flubendiamide can be selected in chemical control.Major Diseases have powdery mildew,
The medicines such as triadimefon, generation height, Tebuconazole, Fluoxastrobin, first frost MnZn, virus A can be used in anthracnose, blight dis-ease, epidemic disease and virosis
Agent.Dead angle is not stayed when spray, it is no that growth, fruit development and quality are influenced it will cause sprawling.
S11 timely collectings
First maturity period of summer and autumn greenhouse watermelon, 28 days maturations after small fruit type kind is spent, 30 days or so maturations of middle fruit type；The
Two batches reduce corresponding extension 2 days with temperature.The ripe harvesting of sale 9 nearby, the ripe harvesting of long-distance export trade 8.It can basis when adopting melon
Fruit skin color or pollination label date carry out maturity discrimination.Harvesting preferably carries out in the afternoon, cuts receipts with scissors, handles with care.It adopts
With shockproof foam net cover and carton package transportation and sale.
This specific implementation is different from existing sowing in the field technology, by the basic principles of soilless substrate seedling transplanting technique
It is attached to existing sowing in the field technology, the technical advantage that both collection coalescence surmounts is realized " 2 " effects of 1+1 ＞, it is easy to operate and easy
In grasp, with obvious effects and reliable and stable, direct production cost therebetween and controllable limited, crop yield synergistic effect
Obviously, it is suitble to large area production application, there is significant creative strong, novelty and practicability.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
