Abstract

A high-yield cultivating method of corns belongs to agriculture and overcomes the shortcoming that an existing planting method is difficult in continuing to increase yield. The high-yield cultivating method of the corns comprises performing deep scarification of furrows at intervals one by one on ridged cultivated land, and applying farmyard manure in a deep scarification layer while performing deep scarification, watering in the furrows after deep scarification and fertilization, sowing seeds in the watered furrows, paving straw in the furrows where the straw is cut in autumn harvest, in the next year performing the deep scarification, fertilization, watering and seeding cultivation in furrows which are idle in the last year, idling the furrows where the seeds are sown and the straw is paved, repeating the cycle, and forming the law that cultivation is performed to each furrow every other year, namely performing alternate cultivation to adjacent furrows on an annual basis. The high-yield cultivating method of the corns has the advantages of water retention and duration of soil fertility-keeping ability. Crops are good in light transmission and ventilation, deep in root system and resistant to lodging. The straw returning to the field keeps warm, preserves soil moisture, resists soil loss and is high in corrosion utilizing rate. A process of stubble cleaning cultivation is omitted. On the premises of saving energy and labor input, the high-yield cultivating method can obviously improve unit area yield of the corns and improve quality of corn kernels.

Description

A kind of corn with high yield is cultivated method

Technical field

The invention belongs to agriculture field, be specifically related to corn planting.

Background technology

Through the ages, improve crop yield, be unable to do without breed improvement, increase fertility of land, rational close planting.Current, important cereal crops maize planting, planting density has reached 45000 strains.The plantation general layout that generally adopts is to plant on the platform of ridge.Requirement based on illumination, ventilation reaches the factor, particularly natural environment variation, decrease in precipitation that lays particular stress on the decline of chemical fertilizer soil fertility for many years, and planting density instantly can not make big fringe kind normal growth.By the planting technology of domestic existence conditions, before new obvious high yielding variety occurred, the per unit area yield of corn was difficult to have significantly again and promotes.Introduce the maintenance of agrotechnique developed country and promote the soil melioration of soil fertility, water, fertile rationally, technology such as make full use of, also have deficiencies such as expense is high, the use and management difficulty is big, economic benefit is undesirable.

Summary of the invention

The purpose of this invention is to provide a kind of corn with high yield and cultivate method, plough basically and broadcast under the cargo handling operation prerequisite continuing to use domestic corn planting, increase substantially maize yield, overcome the deficiency that existing kind of method for planting is difficult to continue increasing both production and income.

Of the present invention kind of method for planting is

1, on the arable land of the ridging that forms furrow, ridge platform, dark at intervals one by one loose furrow, the dark loose degree of depth 30-45cm, dark pine is executed farmyard manure simultaneously on the 20-35cm degree of depth of the face of land in dark pine layer.

2, water in the furrow after dark pine fertilising, sow in the furrow after watering, make plant long in furrow, after planting adjacent two sowing row are also promptly emerged and between the plant row of back two idle ridge platforms and an idle furrow are arranged.

3, stalk is paved in cutting off the furrow of stalk during autumn harvest, be used for the next year corruption and increase soil fertility.

4, next year; In the furrow that leaves unused last year, carry out aforesaid dark pine, apply fertilizer, water, sow farming; The furrow that to sow and be covered with stalk last year is idle, so goes round and begins again, and forming that every furrow next year cultivates also is the rule that adjacent furrow is cultivated per year by turns.More than be basic scheme of the present invention.

The farmyard manure of executing is to add the ight soil that water stirs the chicken or the pig of pulp among the present invention, and fertilizing amount is controlled at and adds preceding 1000-1200 kilograms/mu of water; The water yield that furrow waters before the sowing is controlled at 8 liters/meter; The corn of sowing is selected the big fringe kind of thin planting for use.

The present invention cultivates in the method, and plant is distributed as two strains of a hole or a hole individual plant, and two strain holes are apart from 30-40cm, and the individual plant hole is apart from reducing by half.Per hectare about 45000 strains of keeping a full stand of seedings, seed is broadcast 3-5cm under the furrow face of land.

For under existing tillage condition, making the arable land have the nutritive layer reservoir storage of enough degree of depth, the dark pine among the present invention is deepened year by year, finally maintains the 60cm degree of depth, and in time finishing keeps plough surperficial ridge platform, furrow state.

Good effect of the present invention is: water conservation, to protect fertile soil fertility lasting.The crop printing opacity, ventilate, root system is dark, resistant to lodging.Also field stalk insulation, soil moisture conservation, anti-soil erosion, corruption availability height.Cancellation stubble cultivation process.Under the prerequisite of saving resource and work input, can obviously improve the unit are of corn and produce output and the quality of improving corn kernel.

Description of drawings

Accompanying drawing is emerged vertical ridge, arable land, back to part sectioned view for using the present invention's method of cultivating.

Embodiment

Consult accompanying drawing, in spring, on the ridging that is forming ridge platform, furrow is ploughed, separately furrow 2-1 is one by one carried out dark pine.Form the dark pine layer 3 of 30-45cm.Dark pine is executed farmyard manure 4 simultaneously on the 20-35cm degree of depth of the face of land in dark pine layer.Water in the furrow after dark pine fertilising.Sow in the furrow after watering.The plant of sowing is distributed as two strains of a hole or a hole individual plant, and two strain holes are apart from 30-40cm, and the individual plant hole is apart from reducing by half.Per hectare about 45000 strains of keeping a full stand of seedings, seed is broadcast 3-5 cm under the furrow face of land.The milpa 5 that grows summer.Two idle ridge platforms 1 and an idle then furrow 2-2 are arranged between the adjacent two row plant.The farmyard manure of executing is to add the ight soil that water stirs the chicken or the pig of pulp in the present embodiment, and fertilizing amount is controlled at and adds preceding 1000-1200 kilograms/mu of water; The water yield that furrow waters before the sowing is controlled at 8 liters/meter; The sowing kind is selected the big fringe kind of thin planting for use.

During autumn harvest then, the stalk of accepting is paved in the furrow of being cut off.

Next year repeats aforesaid dark pine in year untilled furrow above that, the stalk when applying fertilizer, watering sowing and autumn harvest paves farming, so goes round and begins again, and in adjacent furrow, cultivates by turns per year.
