Abstract
The invention discloses a method for planting the summer corn to improve the yield, comprising the following steps: selecting density-resisting compact or semi-compact high-quality summer corn to hybridize; sowing the summer corn in the line-indenting broadband densifying form; managing the corn field; and harvesting the corn in good time. Because the line-indenting broadband densifying corn sowing form replaces the traditional equal line-spacing corn sowing form, and the edge line advantage is created manually, the high-density planted corn group structure and the corn group canopy environment are improved, the light source is fully utilized, the stems of the corn are stout, the corncobs are lower, and the lodging of the plants is prevented effectively. Due to the adoption of the line-indenting broadband densifying corn sowing form, the compact summer corn planting density can be increased from about 4500 per mu of the traditional equal line-spacing corn sowing form to 5500 per mu, the semi-compact summer corn planting density can be increased from about 3500 per mu to 4500 per mu, high yield increasing potential can be achieve, the yield can be increased by about 20%, and the light energy utilization efficiency can be increased by more than 18%. The method has good popularization and application value.
Description
Technical field
The invention belongs to the corn planting field, relate in particular to a kind of kind method for planting that improves summer corn output.
Background technology
Corn is the second largest cereal crops of China, is the main force of China's increases in grain production, and the corn yield increasing problem has become the key that solves China's food problem.Summer corn season, the photo-thermal resource was relatively more sufficient, and corn per unit area yield yield potential is still very big.Increasing planting density at present is one of important channel of improving summer corn output; But under line-spacing planting patternss such as tradition, high-density planting often causes colony's interior lights worsening condition, and photo-thermal is not enough in the colony; Serious lodging, thus limited the performance of summer corn yield potentiality.
Summary of the invention
The objective of the invention is to utilize a kind of kind method for planting that improves summer corn output; Be intended to solve the line-spacing planting patterns that waits commonly used in the present production and under high density, often cause photo-thermal deficiency in the maize population; Be prone to the lodging problem, seriously limited the problem of the performance of summer corn yield potentiality.
The object of the present invention is to provide a kind of kind method for planting that improves summer corn output, said method comprises:
Choose compact or half compact high-quality summer corn crossbreed;
The employing line width band density mode that contracts is sowed;
To managing between corn field;
In good time harvesting corn.
Further, the implementation method of seed selection is:
Select compact or half compact high-quality summer corn crossbreed for use, seed quality requires seed purity>=99%, germination rate>=95%, and cleanliness>=99%, water content≤13% is selected the seed of full uniformity for use, to improve emergence rate and colony's regularity.
Further, the implementation method of sowing is:
Seeding method adopts the line width band density mode that contracts, and promptly triplex row corn one broadband is live behind the wheat stubble; Compact kind spacing in the rows 17.3cm, planting density is 5500 strain/mus; Half compact kind spacing in the rows is 21.2cm, and planting density is 4500 strain/mus, seed level 5cm, and the simple grain Precision Seeding can be adopted single file corn drill mechanical planting, and sowing date for early sowing takes the circumstances into consideration to water according to soil moisture content.
Further, seeding method adopts the line width band density mode that contracts, i.e. triplex row corn one broadband, 2 equate little line-spacing 0.55m, add a broadband 1.0m.
Further, the implementation method of field management is:
The extermination of disease and insect pest: controlling underground pest is taked seed is carried out kind of a clothing agent dressing or a dressing seed, availablely contains the agent of insecticide chlopyrifos kind clothing and carries out dressing, or dress seed with medicaments such as phoxim and chlopyrifos.Corn adopts sprayings such as go out young urea and phoxim emulsifiable concentrate to prevent and treat mythimna separata seedling stage; With 5% Imidacloprid missible oil spraying control thrips; Be sprinkled into lobus cardiacus control of maize snout moth's larva but can mix the fine sand mixing with 1.5% phoxim granule, also can contain the phase of sending out and trap and kill with black light lamp the corn borer adult in the toy trumpet mouth phase.The large and small pinta of control of maize can be used 50% carbendazol wettable powder; The corn rust their early stage is with the control of spraying of 25% triadimefon wetting powder;
Controlling weeds: after planting, can directly spray 40% atrazine plus acetochlar during the good conditions for soil moisture; During the soil moisture content difference, corn seedling 3～5 leaves, every mu sprays 4% beautiful agricultural happy suspending agent;
Irrigate: take out male preceding 10 days, back 20 days field soil moisture, should keep field capacity at 75-80%, water deficient will in time be watered, and the field has ponding to want timely draining;
Fertilising: confirm fertilizing amount according to output, generally need use purity nitrogen 2.2-2.8 kilogram, phosphorus pentoxide 0.7-0.9 kilogram, potassium oxide 1.5-2.3 kilogram by 100 kilograms of seeds of every production.On fertilizer application, whole phosphorus, potassium, sulphur, zinc fertilizer base are executed, and 30%～50% of nitrogenous fertilizer total amount is made base manure or topdress seedling stage, and 50%～70% topdressed as typhon mouth phase and pustulation period.Also can select for use the slow control of sulfur-bearing corn special-purpose fertile, in sowing or seedling stage disposable applying.
Further, the implementation method of results is:
It is that the seed milk-line disappears that grouting finishes, and the fruit ear bract is withered and yellow loosening, and the seed hardening is shinny, and water content drops to below 33%.
The kind method for planting of raising summer corn output of the present invention, this method comprises: choose and select compact or half compact high-quality summer corn crossbreed for use; The employing line width band density mode that contracts is sowed; To managing between corn field; The present invention adopts the line width band density seeding method that contracts to substitute line-spacing seeding methods such as tradition, causes limit row advantage artificially, has improved high-density planting maize population structure and maize population Canopy Environment; Increased the light transmittance of middle part canopy; Make full use of the photo-thermal resource, the sturdy and fringe position of cane moves down, and effectively prevents plant lodging under the high density; The population effect of milpa increases lodging resistance under the performance high density.The line width that contracts band density seeding method can make about the 4500 strain/mus of compact summer corn kind planting density by line-spacing seeding methods such as tradition and increase to 5500 strain/mus; Half compact kind increases to 4500 strain/mus about by 3500 strain/mus; Yield potential is bigger; Output can improve about 20%, and utility rate of luminous energy increases more than 18%, and excellent popularization and using value are arranged.
