Abstract
The invention discloses a seedling cultivating method for corn seeds. The seedling cultivating method for the corn seeds is characterized by comprising the following steps of step 1, preparing a seedbed; step 2, accelerating germination of the corn seeds; step 3, seeding; step 4, preparing a nutrient solution; step 5, transplanting. According to the seedling cultivating method for the corn seeds, the operation of the planting method is convenient, the practicability is strong, the germination speed and the germination rate of the corn seeds are effectively improved through a way of combining the accelerating germination and the seedling cultivating, the seedling quality is improved, healthy and strong seedlings are cultivated, and the grain yield is improved.
Description
Technical field
The invention belongs to proportion of crop planting technical field, be specifically related to a kind of corn seed seedling-cultivating method.
Background technology
Corn is Chinese first cereal crops, the cultivated area about 1249.35 square kilometres that corn is total, also known as maize, maize (maize rod), maize, ear of maize.Guangdong language is called maize, and the south of Fujian Province language is called a kind wheat.Being annual gramineae herbaceous plant, is important cereal crops and important feed resource, is also the cereal crops that whole world gross yield is the highest.
Annual bluegrass undergraduate course plant is tall and big, and stem is strong, straight and upright, high 3-5 rice, diameter 2-5 centimetre.Leaf is narrow and large, marginal wavy, and in the both sides alternate of stem, blade is linear to wire lanceolar, long 40-60 centimetre, wide 4-8 centimetre, and tip is gradually sharp, base portion circle or micro-in ear shape, surperficial dirty-green, back side light green, and two sides band cilium, middle arteries and veins is wider, white.Hermaphroditism, male flower inflorescence spike top is raw, and female flower flower fringe armpit is raw, and ripe subsequent valley fringe, the thick axis of tool, develops into two row's seeds after the paired file of small ear.Grain ear is outer to be wrapped up by the abnormal leaf of multilayer, is called foreskin.Fresh and tender stalk is micro-sweet in sugarcane edible.Seed is edible.In the somatic cell of dliploid milpa, chromosome number is 10 right, so the columns of corn is generally even column.
Corn growing season is shorter, requires warm rainy in vegetative period.Corn water consumption is large, if little precipitation, source of irrigation water is not enough, will the underproduction even have no harvest.If first frost in autumn arrives too early, corn was endured cold in the maturing stage, also can the underproduction.
Although corn nutritive value is lower than other cereal, but isomalto-oligosaccharide can be proposed inside corn, isomalto-oligosaccharide is the most excellent in prebiotics, prebiotics is the grain of probio, close relationship is had to the probio breeding of human body, thus poised state is reached to gut flora, make intestinal health.
Industrial corn consumes the Chaoyang industry belonged in Maize Industry, and be fastest-rising part in corn overall consumption, corn processing obtains a lot of application in fields such as food, medicine, chemical industry, is in the fast growth phase, tomorrow requirement promise well.Along with Chinese maize processing industry degree deepens constantly, product chain constantly expands and extend, corn deep processing industry market scale and having a high potential.
Still be in the starting stage to the industrialization development of corn at present, under natural conditions, corn can produce a large amount of seeds, therefore can collect a large amount of corn seeds and breed seedling with seeding method.Report existing bibliographical information, in laboratory, according to conventional seed planting method, germination rate is not high, after the storage of certain means or seed soaking, although the germination rate of corn can significantly improve, how producing a kind of corn high efficiency seedling cultivating method is the technical problem to be solved in the present invention.
Summary of the invention
The object of the present invention is to provide a kind of corn seed seedling-cultivating method, practical, easy and simple to handle, with low cost, and industrialization is effective, bud ratio is high, growth of seedling is good, output increased.
The technical scheme that the present invention takes is:
A kind of corn seed seedling-cultivating method, is characterized in that, comprise the steps:
(1) seedbed prepares: in green house, be paved into into seedbed with Nutrition Soil, drench with 1500-1800 times of thiophanate methyl solution, for subsequent use;
(2) presprouting of seeds: choose the liquor potassic permanganate that full corn seed is placed in 0.05-0.08% and soak 25-30min, clean, stand-by;
(3) sow: the shallow ridges outputing dark 3-4cm on seedbed, by corn seed according to line space 6cm, seed spacing be 2-2.3cm specification equably row broadcast in shallow ridges, shovel from empty ditch fine earth train in cave peripheral thickness be 3-4cm;
(4) nutrient solution processed: add 0.3-0.4%KNO3 according to percentage by weight in natural minerals water, 0.5-0.6% NH4NO3,0.2-0.4%Ca (NO3) 2.4H2O, increased by the solute amount of 0.1% every 10 days, divide and be sprinkled into field three times;
(5) transplant: the seedling growing 3-4 sheet leaf is shifted out cool canopy, transplant according to spacing in the rows 40-50cm, to drench water, keep Nutrition Soil moistening, sprayed the borate of 0.4-0.5% every 1-2 month by the standard of 8-15 g/ strain and biological agent derris extract 300 times of dilutions spray control.
Nutrition Soil in above-mentioned steps (1) is mixture that 2:3:1 forms by humus soil, coconut palm chaff and pearl ground by volume.
Beneficial effect of the present invention is:
Implantation methods of the present invention is easy to operate, practical, is combined can effectively be improved Course of Corn Seed Germination speed, germination rate by vernalization and seedling raising manners, promotes seedling quality, cultivates healthy and strong seedling, improves grain yield.
