Description
Technical field
The present invention relates to a kind of cultural method of black sweet corn.
Background technology
Blank corn is a kind of specific type of corn, and its seed cuticula precipitates to some extent melanin, and outward appearance is pitch-black
It is shinny.Not only color and luster is unique and nutritious for blank corn, and perfume is glutinous good to eat, most preferably eats raw.Seed rich in water-soluble black element and
Various trace elements needed by human, phytoprotein and various amino acid, nutrient content is apparently higher than other cereal crops.With
It is that " jet congee ", " blank corn paste ", " flexible package fresh and tender maize rod " of main Raw material processing etc. are even more market of selling well.Jet
Rice stalk sugar content is higher than conventional corn stalk 1-3 times up to 11.95%.The suitable most of China corn-growing regions plantation of blank corn.
Spring, summer sowing, planting patterns is essentially identical with conventional corn, and cultural method is simple.By mu with terms of 2.5-3 kilogram of seed, can
Harvest fresh and tender ear of maize more than 4000.
The content of the invention
The technical problem to be solved is to propose a kind of cultural method of black sweet corn, and mouthfeel is not only fragrant but also glutinous, dimension
C and micronutrient levels are high, by increasing capacitance it is possible to increase the disease resistance of seedling, disease resistance is higher.
The present invention solves the technical scheme of above technical problem：
A kind of cultural method of black sweet corn, comprises the following steps：
(i) sand loam or cement sandy loam, content of organic matter 1.3-1.5% are selected, acid-base value is Ph values 6.6-6.8, saliferous
Amount is less than 0.3%, and sodium chloride content is less than 0.15%, and level of ground water is carefully broadcast in below 1m, seed upper seeding, and depth is 4-5 centimetre；
(ii) benefit of transplanting seedlings during 3-4 leaves is planted, and to be watered after cultivation with soil when transplanting seedlings, and is carried out in the dusk or cloudy day, every during 5 leaves
1 plant of cave final singling；
(iii) after transplanting, from the beginning of kind of plant hole outer rim, extension 0.3-0.5m, depth 20-25 centimetre, soil are outwards ploughed deeply with reference to basal dressing
Table soil is placed on bottom when earth is backfilled, and subsoil is placed on upper strata, then fully pours water, and makes root soil contiguity；The season of growth, in planting area
Middle weeding, keeps loosing soil, intertills depth 5-7cm, and in tree disk improving straw mulching is used, and cladding thickness is 12-13cm；The base
Fertilizer be strain organic fertilizer 0.5-0.7kg, calcium magnesium phosphate 0.1-0.3kg, urea 0.15-0.17kg, potassium sulfate 0.15-0.17kg,
Sheep excrement 0.5-0.7kg, plant ash 0.7-0.9kg；
(iv) respectively topdress 1 time in jointing stage, heading flowering period and pustulation period respectively, the jointing stage imposes available nitrogen phosphate fertilizer, and phosphoric acid is applied in strain
Two ammonium 0.1-0.2kg；Urea 0.13-0.15kg is applied in heading flowering period Nitrogen Top Dressing, strain；Pustulation period imposes nitrogen-phosphorus-potassium compound fertilizer,
Nitrogen-phosphorus-potassium compound fertilizer 0.14-0.15kg is applied in seedling strain；Disable within 30 days before fruit picking and topdress；
From adopting first 2 with carrying out to adopting first 1 month, nutrient solution is every 15 days blade face spray Foliage nutrient solutions once for foliage top dressing
22-24 gram of composition, composition is added to include following components by weight in every kilogram of water：Ammonium phosphate：15-17 parts, borax：2-
4 parts, boron fertilizer：0.3-0.5 parts, zinc fertilizer：0.7-0.9 parts, iron fertilizer：0.5-0.7 parts, calcareous fertilisers：0.7-0.9 parts, fertiliser containing magnesium：0.7-0.9
Part, molasses fermented liquid：0.7-0.9 parts, Bt milk powder agent：0.7-0.9 parts, isocarbophos：0.3-0.5 parts；
(v) seedling stage soil moisture can not pour water in the 50-60% of maxmun field capacity, and soil moisture should keep after jointing
In the 70-73% of maxmun field capacity；
(vi) 22-28 days sugar content highests after ear leaf is spun, skin is most thin, is harvested.
It is within first 1 month that black sweet corn absorbs micro- best period to adopting from adopting first 2 months, and every 15 days blade faces
Spray Foliage nutrient solution can once, then make black sweet corn absorb trace element to greatest extent, Foliage nutrient solution contain potassium, boron,
The various trace elements such as phosphorus, zinc-iron, molasses fermented liquid then containing amino acid and various nutrient elements, can make black sweet corn mouthfeel
More preferably, while having all to be increased in melanic generation, another Vc and micronutrient levels height；The agent of Bt milk powder and water amine sulphur
Prevention and control of plant diseases, pest control effect is played in the addition of phosphorus.
The technical scheme that further limits of the invention is：
The cultural method of aforesaid black sweet corn, wherein step (iii) in, be mixed into soil and improve liquid, soil in table soil when soil is backfilled
It is 23-25 gram of mixture of addition in every kilogram of water to improve liquid, and mixture includes by weight following components：Fertilizer：45-47
Part, borax：1-3 parts, dithiocarbamate salt derivative：7-9 parts, potassium sulfate：1-3 parts, ammonium phosphate：1-3 parts, molasses are sent out
Zymotic fluid：2.7-2.9 parts.
Being mixed into soil in table soil when soil is backfilled improves liquid, the soil of the present invention improve in liquid containing fertilizer and potassium,
Boron, phosphorus, the nutrient that abundance can be provided for black sweet corn seedling, to promote the root growth of seedling；Borax has the work of desinsection
With seedlings root insect pest can be prevented and treated；Molasses fermented liquid contains amino acid and various nutrient elements, can make black sweet corn mouthfeel
Not only fragrant but also glutinous, Vc and micronutrient levels are high, and the addition of formiate derivative (DTC analog derivatives) on the one hand can catch
Heavy metal in soil, can prevent from containing heavy metal in black sweet corn, on the other hand by the cooperation with molasses fermented liquid, also
The disease resistance of seedling can be increased, disease resistance is higher, obtain unexpected technique effect.
The invention has the beneficial effects as follows：The black sweet corn mouthfeel of present invention cultivation is not only fragrant but also glutinous, and boiling rear soup can drink；This
Bright black sweet corn Vc content is high, Vc of the hectogram containing 5.83-5.95 milligrams；The black sweet corn protein content of the present invention is up to
12.03%, it is higher than conventional corn content by more than 17%；Crude fiber content is high by 16.5%；The black sweet corn micronutrient levels of the present invention
Higher, copper, manganese, Zn content are 1.5-1.65 times of existing blank corn, and calcium content is 1.2-1.3 times of existing blank corn, especially
Be potassium content be 1.35-1.45 times of existing blank corn, the content of selenium is 1.35-1.45 times of existing blank corn；17 kinds of amino
There are 12 kinds in acid higher than existing blank corn；The melanin content of the black sweet corn of the present invention is high, the 1.3-1.5 of existing blank corn
Times, other black crops are mostly that the black interior reality of cortex is white, and black sweet corn is then that the transparent interior solid black of crust is bright.
