Abstract

Small sheds are adopted for carrying out seedling cultivation for green Chinese onions in the Spring, high-quality seeds are selected, a seed bed is well maintained, sufficient water and fertilizer are applied, bud forcing treatment is carried out on the seeds, then fine earth with 20-30 times of the weight of the seeds is evenly mixed with the seeds, and the seeds are sown in the middle ten days of the March. Sufficient water and fertilizer are applied in a growing period, weeds in the seed bed are removed, ventilation and cooling are carried out when the temperature in the small sheds reaches 35 DEG C, and the temperature in the small sheds is maintained between 25 DEG C to 35 DEG C. Hardening of seedlings, exercising the seedlings and strong seedling promotion are carried out in the middle ten days of the May. According to investigation and statistics, the average stem diameter in the spring seedling process is 0.9cm, the average plant height is 55cm, the average root length is 10cm, the average number of roots is 29, the average stem length of the green Chinese onions is 3cm to 4cm, the rate of seedlings of the first grade reaches more than 80%, the average yield per mu is 2825 kg after transplantation, the average unit price is one yuan, and the average income per mu is 2825 yuan. The spring seedling cultivation for the green Chinese onions enables the seedling cultivation for the green Chinese onions to develop towards double-season and diversification modes, planting time is short, cost is low, and time and labor are saved. The spring seedling cultivation can provide sufficient green Chinese onion seedlings of high quality, and the industry of the green Chinese onions is made to be developed stably and continuously.

Description

Shallot seedling-cultivating method in spring

Technical field

The present invention's design is a kind of shallot seedling-cultivating method in spring.

Background technology

It is the basis of shallot cultivation that shallot is grown seedlings, and cultivates the prerequisite that be shallot high yield strong sprout.Shallot in all parts of the country is grown seedlings and mainly adopts grow seedlings autumn, is generally in 9 months, sows the last ten-days period, and next year, 5-6 month transplant planting, reached 9-10 month breeding time, and breeding time is long, and production cost is high, and field management is difficult, directly has influence on the development of shallot industry.Grow seedlings spring and can promote shallot to grow seedlings to two seasons, development in pluralism, for shallot produces the green onion seedling that enough high-qualitys are provided, make that shallot industry can be stablized, sustainable development.

Summary of the invention

For solving the grow seedlings technological deficiency of middle existence of shallot, I successfully sum up shallot seedling-cultivating method in spring by planting experimentally for many years.

The present invention is designed to the technical scheme that technical solution problem is taked: (one) seeding and seedling raising: 1, seed quality: select mature and plump, color black and bright, quality reaches country-level breeding (purity 97%, cleanliness 99%, germination rate 93%, water content < 10%) seed; 2, seedbed arranges: selection physical features is smooth, leeward on the sunny side, irrigation is convenient, the plot of fertile soil, and 667m2 executes high-quality farmyard manure 5000kg, superphosphate 50kg; The stubble-cleaning of turning over, meticulous whole ground, is then made into long 10m, the seedling furrow of wide 1m; 3, seed treatment: seed is put into clear water and stir 10 minutes, pull not plump seed and impurity out after water is static, then use the hot-water soak 20-30 minute of 50-55 ℃, or soak 20-30 minute with 0.2% potassium permanganate; 4, the amount of broadcasting and time: the 667m2 amount of broadcasting 2kg, sowing mid-March; 5, type of seeding: seedling furrow water vola water, until water ooze dry after, after seed weight 20-30 fine earth is doubly stirred evenly with seed, spread fertilizer over the fields on furrow face, earthing 1cm then, after 2-3 days, pine is harrowed once; (2) field management: 1, rich water quality management: growth 667m2 in early stage executes the night soil 200-300kg that becomes thoroughly decomposed, growth most productive period foliage-spray potassium dihydrogen phosphate 1 time, in conjunction with watering, mu spreads fertilizer over the fields urea 15kg; Growth of seedling waters little water 1 time in earlier stage, and the growth most productive period waters 3-5 time depending on soil moisture content; 2, thinning weeding: pull out in time seedling field weed after seedling is neat.Early April thinning, late April final singling, seeding row spacing 4 * 7cm, mu stays seedling 23.8 ten thousand strains, and 1:10-15 is compared in seedling field; 3, restraining the growth of seedlings: May, early and middle ten days height of seedling reached 50cm, stopped rich water during 5-6 leaf, restrained the growth of seedlings; 4, temperature control measure: shallot is grown seedlings and adopt little shed to grow seedlings spring.After planting, first with long 1.5m, the bamboo bar of thick 1cm is at seedling furrow both sides inserted link arch circle, and spacing 50-60cm, then covers long 11m, wide 1.5m, the canopy film of thick 0.015mm.Because temperature is low, generally do not leak informaton March, during every morning 9-10, will beat with smooth wicker canopy film, removes dew, increases light transmittance, improves temperature of shed, promotes growth of seedling.When temperature of shed reaches 35 ℃, should open in time shed two canopy film April, aeration-cooling, and evening, overlay film, made temperature of shed remain to 25-35 ℃.In May, along with the rising of temperature, evening, whole day was ventilated without blocking air port.In 5 months, take the canopy film on seedling furrow the last ten-days period off, restrain the growth of seedlings, hardening, promotion strong sprout; 5, play transplantation of seedlings: according to just, the different transplanting time liftings of second crop in multiple cropping green onion, lifting first waters to seedbed for first 2 days, wants strict classification binding after lifting.

Beneficial effect of the present invention: grow seedlings through 2009-2012 shallot in continuous 4 year spring, 10 mu of annual seedlings growing areas, the investigation statistics thick 0.9cm of average stem that grows seedlings spring, plant height 55cm, the long 10cm of root, 29 of radicals, the long 3-4cm of green onion stem, one-level seedling reaches more than 80%, and after transplanting, average yield per mu is 2825 kilograms, 1 yuan of average unit price, 2825 yuan of incomes per mu.Shallot is grown seedlings and shallot is grown seedlings realized new technological leapfrogging spring, and implantation time is short, and cost is low, and saving of work and time is worthy of popularization.

Embodiments of the present invention: shallot seedling-cultivating method in spring can be by the mode penetration and promotion such as hold that training class and field are instructed on the spot.

Claims

1. a shallot seedling-cultivating method in spring, is characterized in that the current shallot in all parts of the country main seedling-cultivating method in autumn that adopts of growing seedlings, and reaches 9-10 month breeding time, and breeding time is long, and production cost is high, field management difficulty; Shallot seedling-cultivating method in spring can promote shallot to grow seedlings to two seasons, development in pluralism, for shallot produces the green onion seedling that enough high-qualitys are provided, makes that shallot industry can be stablized, sustainable development.
