Abstract

The invention relates to an ultrahigh-yield summer maize cultivation novel technology. According to the invention, through the processes of finely selecting an improved variety, finely sowing, improving density, applying sufficient fertilizer, finely managing, controlling weeds and pests, and the like, effects of preventing summer maize pest and disease, increasing yield and increasing efficiency can be realized. The technology is suitable for summer maize high-yield cultivation.

Description

A kind of Super-high Yield Summer Maize new cultivation technology

Technical field

The present invention relates to proportion of crop planting field, specifically a kind of Super-high Yield Summer Maize new cultivation technology.

Background technology

The kind that summer corn is promoted is at present more. Peasant cannot grasp breediness effectively, and that is engaged in Maize Production mostly is old man, women etc., and a little less than accepting new technology ability, Comparison of Management is extensive, and disease and pest presents aggravation trend, causes yield of Summer Corn, Quality Down.

Summary of the invention

The present invention solves the technical problem that summer corn low yield exists, and invents a kind of Super-high Yield Summer Maize new cultivation technology.

The present invention is for solving the problems of the technologies described above, the technical scheme of taking, and a kind of Super-high Yield Summer Maize new cultivation technology, its special character is to comprise following process:

1. selected breeding. Selected kind requires plant type compactness, resistance to dense planting, resistant to lodging, density to reach more than 5000 plants/acre non-lodging, not empty bar, not bald point, the heavy potentiality of average single fringe grain are more than 200 grams, select seed of the same size, soak seed 8 hours, dry rear use 40% methyl Ethodan and 2% Garrick show, by 0.2% seed dressing of grain weight, control rough dwarf disease, seedling blight, smut and subterranean pest-insect. 2. meticulous sowing. Broadcast the front meticulous whole ground of ploughing, mu is executed 3 cubic metres of high-quality chicken manures, 10 kilograms of phosphorus pentoxides, 30 kilograms of potassium oxides, 1 kilogram of zinc fertilizer, 5% 1.5 kilograms of phoxim granules, sowing in 5～15 June, the plantation of size row, wide row space is 80～90 centimetres, little line-spacing is 30～40 centimetres, 3～4 kilograms of program request mu sowing quantities, mu is executed 5 kilograms of composite fertilizers and is done seed manure, seed manure isolation, the earthing depth is consistent, and thickness is 3 centimetres. 3. improve density. Every mu of 6000～7000 strains of thickness of sowing, thinning in time, final singling. Paid strain number while guaranteeing to gather in the crops is more than every mu of 5500 strains. 4. enough fertilisings. Generally use 3 kilograms, nitrogen (N) by every production double centner seed, 1 kilogram, phosphorus (P2O5), 3 kilograms of calculating of potassium (K2O); Phosphorus, potash fertilizer are made base fertilizer; Nitrogenous fertilizer seed manure is gently executed, ear manuer heavy dressing, granulated fertilizer are drunk and executed. 5. precision management. Emerge and meet the necessary irrigation of drought during toy trumpet mouth. After the typhon mouth phase, to reach earth's surface see wet lose dry. After seedling, to general intertillage of toy trumpet mouth phase 2～3 times, keep loosing soil. Control of weeds: before emerging after broadcasting, be watered 30～50 kilograms with 100～120 milliliters of 50% acetochlor ecs and be sprayed on ground. The control of rough dwarf disease: only prevent and treat small brown rice planthopper with aphid lice seedling stage. Two, three generations mythimna separata and thrips: with 1000 times of 50% phoxims and 2000 times of liquid spraying controls of DDT EC, the control time is in seedling stage and fringe phase, double corn leaf aphids and the Spilosoma urticae controlled. Corn borer: with 3% phoxim granule, 250 grams every mu, add 5 kilograms of fine sands, be sprinkled into lobus cardiacus in the corn toy trumpet mouth phase. Maize aphids: save stem brush with 100 times of liquid of Azodrin on maize ear and prevent and treat. In the time just taking out hero, pull out 1/2nd (interlacing or every strain) of full field tassel, after pollination finishes, more remaining tassel is all pulled out. In the pollination later stage by strain inspection pollination situation, to the not fresh filigree artificial supplementary pollination of pollination, to increase grain number per spike. Empty stalk strain was pulled out in 10 days after supple-mentary pollination.

Technique effect

Technique effect of the present invention is, adopts technique scheme, can realize Super-high Yield Summer Maize cultivation, and this mode can allow summer corn avoid the effect of disease and pest, volume increase, synergy, has vital booster action for the high-yield culturing of summer corn.

Detailed description of the invention

1, selected breeding. Selected kind requires plant type compactness, resistance to dense planting, resistant to lodging, density to reach more than 5000 plants/acre non-lodging, not empty bar, not bald point, the heavy potentiality of average single fringe grain are more than 200 grams, about summer sowing 105 days, select seed of the same size, soak seed 8 hours, dry rear use 40% methyl Ethodan and 2% Garrick show, by 0.2% seed dressing of grain weight, control rough dwarf disease, seedling blight, smut and subterranean pest-insect. 2. meticulous sowing. Broadcast the front meticulous whole ground of ploughing, mu is executed 3 cubic metres of high-quality chicken manures, 10 kilograms of phosphorus pentoxides, 30 kilograms of potassium oxides, 1 kilogram of zinc fertilizer, 5% 1.5 kilograms of phoxim granules. Sowing in 5～15 June, the plantation of size row, wide row space is 80～90 centimetres, and little line-spacing is 30～40 centimetres, and mu is executed 5 kilograms of composite fertilizers and is done seed manure, seed manure isolation, the earthing depth is consistent, and thickness is 3 centimetres. 3. improve density. Every mu of 6000～7000 strains of thickness of sowing, thinning in time, final singling. Paid strain number while guaranteeing to gather in the crops is more than every mu of 5500 strains. 4. enough fertilisings. Generally use 3 kilograms, nitrogen by every production double centner seed, 1 kilogram, phosphorus, 3 kilograms of calculating of potassium; Phosphorus, potash fertilizer are made base fertilizer; Nitrogenous fertilizer seed manure is gently executed, ear manuer heavy dressing, granulated fertilizer are drunk and executed. 5. precision management. Emerge and must irrigate to meeting drought during toy trumpet mouth, after the typhon mouth phase, will reach earth's surface and see and wetly lose dryly, after seedling, to general intertillage of toy trumpet mouth phase 2～3 times, keep loosing soil, the control of rough dwarf disease: only prevent and treat small brown rice planthopper with aphid lice seedling stage. Two, three generations mythimna separata and thrips: with 1000 times of 50% phoxims and 2000 times of liquid spraying controls of DDT EC, the control time is in seedling stage and fringe phase, double corn leaf aphids and the Spilosoma urticae controlled. Corn borer: with 3% phoxim granule, 250 grams every mu, add 5 kilograms of fine sands, be sprinkled into lobus cardiacus in the corn toy trumpet mouth phase. In the time just taking out hero, pull out 1/2nd of full field tassel, after pollination finishes, more remaining tassel is all pulled out. In the pollination later stage by strain inspection pollination situation, to the not fresh filigree artificial supplementary pollination of pollination, to increase grain number per spike. Empty stalk strain was pulled out in 10 days after supple-mentary pollination.
