Abstract

The invention discloses a method for cultivating black waxy corn. The method for cultivating the black waxy corn comprises the steps of seed selection, land selection, land preparation, seedling cultivation, transplantation, field management and timing harvest. The black waxy corn cultivated through the method is healthy and strong in growth, high in growing speed, high in yield and good in quality, and plant diseases, insect pests and the using amount of farm chemical are reduced. Further, a soil conditioner in the method improves product quality, reduces harmful accumulation, effectively improves the farmland fertility, improves the soil fertilizer supplying environment, and can free soil, enhance the soil granular structure, improve the moisture and fertility preservation capability and increase soil organic matters.

Description

A kind of implantation methods of black waxy corn

Technical field

The present invention relates to a kind of implantation methods of black waxy corn.

Background technology

It is edible that black waxy corn can be done vegetables, fruit, also can be processed into can, quick-frozen food or local delicacies, collection look, perfume (or spice), sweet, stick at all over the body, soft fine and smooth, excellent taste; Its vitamin, mineral matter and calcareous content are high, have good health care, beautification function; Traditional black waxy corn is in the process of plantation, for prevention and elimination of disease and pests has to spray a large amount of agricultural chemicals; In addition, because traditional black waxy corn implantation methods is used chemical fertilizer for a long time, harden in the plot that makes to plant black waxy corn, degradation reason causes the output of black waxy corn seriously to glide under fertility, more seriously because use a large amount of chemical fertilizer and agricultural chemicals makes the quality of black waxy corn have not a particle of guarantee, meanwhile, traditional black waxy corn produce its in production management process, also have loaded down with trivial details, the amount of labour used is large, production efficiency is low, cost is high, the feature such as of poor benefits.

Summary of the invention

The object of the invention is to provide a kind of implantation methods of black waxy corn.

The present invention adopts following technical scheme:

The implantation methods of black waxy corn, comprising:

(1) seed selection: select healthy and strong, good corn seed, be first placed under sunlight and shine 2-3h, then use 8-10% alcohol solution dipping 3-5s, pull out and dry, then seed is put in to 25-33 ℃ of maintenance 2-3 days;

(2) selection of land, whole ground: the Shajiang black soil that selection is ventilated, nutrient component is high, soil deeptillage, the soil conditioner of filling 0.8-1.2cm thickness at soil subsurface 5-6cm place, described soil conditioner adopts following formulation weight part: zeolite powder 120-125, nanometer jade powder 4-6, neopelex 2-3, dolomol 3-4, talcum powder 4-5, white granulated sugar 3-4, sodium lignin sulfonate 2-3, morpholine 2-3, medical stone 10-12, urea 3-4, zinc sulphate 4-5, ferrous sulfate 5-6, sodium metasilicate 3-4, water are appropriate; Preparation method adds suitable quantity of water by zeolite powder, medical stone, urea, talcum powder to grind to form slurry, be heated to 70-80 ℃, add nanometer jade powder, neopelex, dolomol, white granulated sugar, sodium lignin sulfonate to continue to grind 40-60 minute, concentrate drying, finally add other residual components, stir, granulation, obtains;

(3) grow seedlings: selective light is done seedbed according to sufficient, the unobstructed plot of draining, before sowing, with 25% dimehypo water solution seed dressing, consumption is that 1 part of 25% dimehypo water solution adds 20 parts of 1.5 parts of seed additions of water, piles vexed 1.5-2.0h, dries rear sowing;

(4) transplant: until step (3), bring out after seedling, the large Tanaka after seedling replanting to step (2) is processed, control distance between rows and hills is 80cm * 60cm; After transplanting, topdress, the described mu consumption that topdresses is nitrogen-phosphorus-potassium compound fertilizer 90-110kg, fused calcium magnesium phosphate 10-15kg, manganese sulphate 3-5kg, ammonium molybdate 1-3kg, sodium molybdate 3-5kg, zinc sulphate 1-2kg, urea 30-50kg, ferrous sulfate 10-15kg, zinc sulphate 2-4kg and copper sulphate 5-8kg;

(5) field management: when the high 20-25cm of seedling, should note destroying other sprouting, to reduce nutrient consumption, and spray 1500 times of liquid of buprofezin, 600 times of liquid of mancozeb, prevent and treat the disease of stunting; During height of seedling 60-70cm, attention control banded sclerotial blight, can spray in the usual way jinggangmeisu; Enter jointing-booting stage, spray foliage fertilizer, the boron fertilizer that described Foliar Spraying is 0.2-0.3% and the potassium dihydrogen phosphate of 0.2-0.3% each 1-2 time, and irrigate in time, keep ground moistening degree rate 68-75%;

(6) timely collecting: while gathering, left hand is held stem stalk, and the right hand is held corncob, firmly one draws and can break down; The in season bud of gathering does not expose too not of a specified duration in the sun, generally early in the morning or gather as good at dusk.

Beneficial effect of the present invention:

The black waxy corn robust growth of the present invention's cultivation, fast growth, output is high, quality better, thus damage by disease and insect is reduced, the usage amount of agricultural chemicals reduces, and soil conditioner of the present invention improves product quality, reduces harmful accumulation, effectively improve Cultivated-land Fertility, improve fertilizer provision from soil environment, can chesson, strengthen soil aggregate, improve preserve moisture and fertility ability, increase the soil organic matter.
