Abstract

Provided is a corn planting method achieving yield increase, pertaining to the technical field of agricultural plantation. The invention especially relates to a corn-planting method. The invention provides a corn planting method achieving yield increase which is scientific and reasonable and yields uniform corn and helps increase yield. The corn planting method achieving yield increase is characterized by comprising following steps: 1, selecting land: generally selecting land plots with flat terrain, thick soil layers, good ventilation, water retention and fine fertility-keeping performance; 2, sowing in time: carrying out sowing operation till earth temperature is kept above 14 DEG C from the end of January to the middle ten days of February; 3, adopting sowing methods including seedling transplantation and direct seedling; 4, planting in a standardized mode: reasonably determining planting density and the number of plants per mu based on strain characteristics, soil, fertilizer and water conditions and a planting method and factors like field management level; 5, applying fertilizers by taking a scientific formula and calling for the use of farmyard manure. The method of seedling transplantation is only adopted at places with a water source near and protected, fertile soil, easy operation and convenient operation and otherwise not adopted.

Description

A kind of volume increase corn planting method

Technical field

The invention belongs to agricultural plantation technology field, especially relate to the implantation methods of a kind of Semen Maydis.

Background technology

Originate in Hispanic Mexico and Peru along Andean the foot of a mountain one band, be the staple food crops cultivated of Indians, be the only small grass of build originally, like high temperature, cultivate through America aboriginal, after many generations, relatively large Semen Maydis just occurs. Beyond America, original producton location, China is one of area of popularizing the most of corn planting. Semen Maydis is also the cereal crops that whole world total output is the highest. But China's existence conditions is general without water source irrigation conditions, and mainly by natural precipitation seeding corn, often by drought impact, it develops in grain-production. It addition, the field management aspect of Semen Maydis there is also some problems, make Semen Maydis size uneven, affect yield.

Summary of the invention

The present invention is aiming at the problems referred to above, it is provided that a kind of one scientific and reasonable, that Semen Maydis size can be made uniformly to increase yield increases production corn planting method.

To achieve these goals, the present invention adopts the following technical scheme that.

A kind of volume increase corn planting method, it is characterised in that comprise the following steps.

One, choosing ground: maize root system is flourishing, adaptability is also strong, and it is not strict to the requirement of soil type, but milpa is tall and big, root system is many, it to draw substantial amounts of moisture and nutrient from soil, so generally we will select physical features flatter, soil layer is deep, quality is loosened, permeability is good, and more than middle fertility, water conservation, the good plot of keeping fertility, could obtain higher yield. Our cloud peak is except part cold immersed field, and all the other most fields are adapted to maize planting.

Two, beginning sowing in good time, by the end of January to mid-February, ground temperature is stable could be sowed more than 14 DEG C. With good conditionsi should adopt covering with ground sheeting heat preservation technology measure, avoid frost season and can sow. Therefore according to this climatic characteristic, sowing when answering accurate assurance to rob opportunity.

Three, seeding method, seeding method has culturing and transplanting seedlings and live two kinds. The main alternative condition of culturing and transplanting seedlings is that water source is near and secure, and soil is fertile, easily operates, it is simple to management, otherwise not can select that the method. My 5��June of ground, many high temperature and droughts, therefore mostly adopted sowing in the field mode to sow. This method is point two ways again: one, for beat nest method in advance, is accomplished fluently nest by specification, do not sowed for before treating saturating rain 10��20 days, just sowing when raining; Another kind is to wait saturating rain directly to sow when coming.

The factors such as four, standardized planting, should according to variety characteristic, soil, fertile, water condition, planting patterns, field management level, rationally determine every mu of planting density and strain number. Should grasp flexibly according to plant type, plant height, soil girth of a garment degree. Generally should follow that " dense-type variety should be close, and flat-type kind should be rare; Early seasonal strain should be close, and seasonal strain should be rare; Early sowing should be close, and late sowing should be rare " principle. In order to improve land utilization ratio, reach the purpose of high yield, should suitably increase a mu strain number. , soil fertility good village group flatter in soil, should expand Semen Maydis normalization cropping pattern.

Five, scientific formula fertilising, advocate and use farm manure, chemical fertilizer with the use of mu farm manure 1000kg, corn formulation composite fertilizer special 35��40kg, calcium superphosphate 60��80kg, potassium sulfate 10kg, zinc sulfate 2kg, apply earthing in plantation ditch and make base fertilizer after mixing.

As a kind of preferred version, enhance field management 1. fill the gaps with seedlings in time, thinning, final singling carry out lacking nest after emerging in full field 85% in time and reseed, the seed after soaking can be taked directly to reseed, can also taking the maize seedling educated in advance or unnecessary Seedling selection rainy weather is filled the gaps with seedlings and guaranteed full stand, thinning is urgent.

Beneficial effect of the present invention.

The present invention by choosing ground, begin sowing in good time, the mode such as seeding method, standardized planting and scientific formula fertilising, make Semen Maydis growing way be guaranteed, and corncob size be uniform, increase yield, farmers' income can be increased considerably, matters are promoted.
