Description

High mountain tubule green onion drought floating method for culturing seedlings
Technical field
The present invention relates to crops seedling breeding technical field, and in particular to high mountain tubule green onion drought floating method for culturing seedlings.
Background technology
Tubule green onion (Allium schoenoprosum), the perennial perennial plant of Liliaceae allium.The green onion quality is tender, Fragrance is denseer, quality better, with important edible, medical, industrial and scientific research value, is increasingly subject to the favor and attention of people.
Tubule green onion has the gas of pungent fragrance, and pungent is denseer, is to cook one of necessary article of various dish.Because the green onion contains There is the volatile oil of tool penetrating odor, when for cooking, can remove the peculiar smell such as the smelling of fish or mutton in greasy dish, the special perfume (or spice) of generation Gas, the secretion for the liquid that can stimulate digestion, improves a poor appetite;The volatility Capsaicin contained by it has stronger sterilizing ability simultaneously, when When Capsaicin is discharged by sweat gland, respiratory tract, urinary system, sweating, eliminating the phlegm, profit are played in the secretion of the related body of gland of energy minimal irritation The effect of urine, so as to improve the resistance of human body, preventing respiratory infectious disease;Further, it is also possible to stimulate circulation, improve god Through systemic-function, prevention of cardiovascular disease, senile dementia are had certain effect;Due to rich in substantial amounts of vitamin and mineral Matter, it may have certain nutrition health-care functions.
Tubule green onion is in recent years in China's high mountain large-scale plantation, production and processing, and sell.Product main exit to Southeast Asia and Some countries of west, are an economic benefit very high vegetable varieties, and development prospect is very wide.
But green onion seed is small, rice shoot root system is shallow, weak to rich water absorbability.Therefore the quality of institute's seedling raising is fine or not, direct shadow Ring and arrive yield.China typically uses traditional soil seedling raising mannerses, there is that seedling stage is long, and survival rate is low after field planting, extensive management, wave The problems such as taking seed.The foreign exchange earning vegetables of current China quickly grow, and the increase and entry to WTO of global vegetables demand are again me The Vegetables Exportation of state provides new opportunity, and the domestic and international market occupancy volume of tubule green onion in recent years also increasingly increases, to its quality Requirement also more and more higher.As the early stage important step of modernization vegetables production, the quality of seedling is directly affected after field planting The overall quality of vegetables.In order to produce the high standard tubule green onion seedling for adapting to market demands, a kind of seed consumption is few for research, educate The seedling-raising technique that seedling amount is big, well developed root system, transplanting survival rate are high, seedling is healthy and strong, overcomes the shortcomings of traditional seedling-raising technique, promotes high The sound development of mountain tubule green onion industry is significant.
The content of the invention
The present invention discloses the non-irrigated floating method for culturing seedlings of high mountain tubule green onion, and this method mainly has following measures:Build seedling raising greenhouse, Nursery pond is set, seedling medium, sterilization, seeding method, the floating seedlings nursing plate of combination drought, the depth of water control in nursery each stage is prepared And canopy temperature control system, moss, green alga prevent and kill off, the prevention and control of plant diseases, pest control, the fertilising in nursery each stage etc., seedling quality has been obtained effectively Ensure.
In order to achieve the above object, the present invention uses following technical measures:
High mountain tubule green onion drought floating method for culturing seedlings:
(1) seedling raising greenhouse is built
(2) non-irrigated floating device for raising seedlings is set
Non-irrigated floating device for raising seedlings, including several nursery units and nursery pond;Several nursery cell distributions are in nursery pond Bottom;
Described nursery unit includes seedlings nursing plate and pallet, and seedlings nursing plate is erected on pallet;The bottom of the seedlings nursing plate hole slot Portion is provided with the first permeable hole;Gap between the bottom of the pallet, each hole slot bottom of correspondence seedlings nursing plate, is provided with upward Projection, after seedlings nursing plate is erected on pallet, raised height is higher than hole slot bottom;The bottom of pallet correspond to each of seedlings nursing plate The bottom of hole slot, is provided with the second permeable hole, and described seedlings nursing plate includes seedling medium;
(3) seedling medium is prepared
Peat in mass ratio:Perlite=2:1-4 proportional arrangement seedling medium, substrate with water mixes wet, water content 60- 80%;
(4) seedlings nursing plate is sterilized
New building is not sterilized, and old disk is used with potassium permanganate or formalin or after bleaching liquid disinfectant;
(5) medium in tray and sowing
The matrix prepared is loaded in seedlings nursing plate, 5-7 seeds are broadcast in hole, and seed will be placed on the center in hole, cover and educate after broadcasting Seedling matrix 0.4-0.6cm;
(6) temperature, depth of water management
Sowed during 18-22 DEG C of daytime temperature, whole nursery stage, the water level in control pallet is on seedlings nursing plate hole slot, greatly Canopy temperature:20-25 DEG C, described water is the irrigation water containing fertilizer;
(7) nursery pond moss, green alga are prevented and kill off
(8) prevention and control of plant diseases, pest control
(9) apply fertilizer
30kg nitrogen-phosphorus-potassium compound fertilizers are dissolved in 4-8m3The irrigation water containing fertilizer in above-mentioned steps (6) is produced in water; Described irrigation water is base manure, is topdressed when green onion seedling grows into 5cm or when growing second green onion pipe, topdresses and chased after by base manure amount of application Plus;
(10) transplant
In the process described above, it is preferred that described tubule green onion is European tubule green onion;
In the process described above, it is preferred that nursery pond moss, the method prevented and kill off of green alga include in step (7):Sowing It is afterwards 98%CuSO with mass fraction every 3d42000 times of liquid are sprayed, and are sprayed altogether 3 times, each 15L/667m2;Spray If running into continuous rainy weather >=7 day after three times, rain stop after with mass fraction be 98%CuSO42000 times of liquid sprayings spray one again It is secondary.
In the process described above, it is preferred that pest control method includes:After planting per 667m2Disliked with 30% first frost Mould clever 2000 times of liquid 15L are sprayed 1 time;Sprayed once every 10-15d afterwards, the same first of dosage 30% frost is disliked during nursery Mould clever 2000 times of liquid is sprayed 2-4 times altogether;Using the latent fly adult of physical method preventing and treating of yellow card's trap, thrips class pest, if finding There is above-mentioned larva, sprayed 1 time with 2.5% efficient cyhalothrin emulsifiable concentrate, 2000 times of liquid.
The present invention is compared with general planting technology, with advantages below and effect:
Method for culturing seedlings of the present invention and the field seedling raising method contrast of traditional peasant household greatly reduce manpower and materials, and sowing quantity is only needed to The 1/3 of field seedling raising seed, planting percent is higher than peasant household field seedling raising by 60%.Traditional nursery damping-off, the samping off incidence of disease are general Up to 20%, serious up to 60%, seedling dissipates, and is colonized pretty troublesome, takes a lot of work irregular, survival rate about 80%;Sprout term disease hair of the present invention Sick rate is less than 5%, and straight uniform of emerging, good lifting does not dissipate and sticked together, and transplants fast;Due to well developed root system, survival rate more than 95%, Late growing stage is vigorous, and the incidence of disease is low.Nursery stage is short, and 50-60d is only needed from being seeded into transplant.
