Description

A kind of summer corn cultivation method

Technical field:

The present invention relates to proportion of crop planting technical field, be specifically related to a kind of summer corn cultivation method.

Background technology:

Corn (formal name used at school: Zea mays), Chinese first cereal crops, main producing region is positioned at large corn belt, third place in the world---Chinese Pine the Liao Dynasty corn belt, Plain [1].Approximately 1249.35 square kilometres of the total cultivated areas of corn, also claim maize, maize, 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 highest cereal crops of whole world gross yield.

Corn in June, plantation in July, is called summer corn, or is called Summer Maize.

And the average per unit area yield of some regional corn is very low, this is that environment due to certain areas self causes, and what in such situation, common implantation methods just cannot be good can make corn yield increasing, will bring unnecessary economic loss like this.

Summary of the invention:

Technical problem to be solved by this invention is to overcome existing technological deficiency a kind of summer corn cultivation method that a kind of method is reasonable, plantation is convenient, planting effect is good is provided.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A summer corn cultivation method, is characterized in that: comprises the following steps,

Step 1, kind are selected: select about 100 days breeding times, compact, resistance to close type medium variety, such as No. 11, Zheng Dan 958 ,Xian Yu335,Zhong section etc.Before broadcasting, carry out seed cleaning, use capsuled seed, the seed of dressing does not adopt bactericide and insecticide to mix seed dressing;

Step 2, early sowing while robbing: before June 15, needed that all sowing is complete by seed, pouring " cover-head water " immediately after broadcasting;

Step 3, meticulous sowing: during sower operation, travel speed is no more than 4km/h, promote mechanization precise hole sowing technology, selects germination rate at more than 95% seed, determines density of reserved seedlings before sowing.Sowing depth 3-5cm, uniformity, earthing covers tightly, the mu amount of broadcasting 2-2.5kg;

Step 4, rationally increase density: adopt line-spacing 60cm kind to plant.The density of reserved seedlings of compact how rice kind is 4500-5000 plant/acre, and the density of reserved seedlings in high-yield field is 5000-5500 plant/acre, and high density plot will be strengthened rich water and drop into;

Step 5, scientific formula fertilising: use sufficient seed manure, heavily chase after ear manuer, mend and execute colored granulated fertilizer.During sowing, use nitrogen-phosphorus-potassium compound fertilizer 20-25kg and do seed manure, fertilizer will be used with kind of sublayering or branch;

Step 6, do field management well:

6.1, seedling management: chemical weed control, before after planting emerging, use atrazine plus acetochlar evenly to spray ground, after emergence of corn, the 3-5 leaf phase can be carried out cauline leaf processing with the phonetic green bristlegrass of cigarette, Yu Nongle, cultivated outstanding person etc.In the timely thinning of 4-5 leaf phase, final singling.The damage by disease and insect such as the cotton bollworm in time control seedling stage, plant hopper, Sweden fly;

6.2, fringe period management: the heavy dressing typhon mouth phase is fertile, and every mu imposes urea 25-30kg, adopts the middle-size and small-size cultivator-fertilizer of corn to topdress.The corncob phase will have been filled with water twice in conjunction with precipitation, before and after typhon mouth, is taking out male front and back for the second time for the first time, and irrigation quantity suitably strengthens;

6.3, final-period management: the phase combination of flower grain is watered or rainfall imposes granulated fertilizer, and mu is executed urea 8-12kg.Middle and later periods needs artificial supplementary pollination and emasculation;

Step 7, harvest in proper late: corn is received 1 day every night, thousand kernel weight increases 3-4g, and harvest corn period is generally in early October.

Beneficial effect of the present invention is: very simple, easy-to-understand of above-mentioned step, and very clear, be applicable to professional plant personnel or common staff's reference and use.And above-mentioned steps adopts common, the conventional fertilizer such as urea mostly, cost compare is cheap.The inventive method rationally, plantation is convenient, planting effect is good.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.

A summer corn cultivation method, is characterized in that: comprises the following steps,
