Abstract

The invention belongs to a new technology for agricultural field. It relates to a method for increasing production of corn, which bases on agricultural systematic engineering function. The method employs crop rotation in alternate line, and uses not stubble as nutrient for corn, which increases land capability in the long run. The plantation in alternate line improves the venting and sunshine condition, which promotes crop production. The invention also combines tectorial technology, drip irrigation, close planting, integrated land utilization and no-tillage together for great production increase.

Description

A kind of corn planting volume increase new method

The technical field agricultural

The background technology corn is the main dry crop of the northern area of China, and its kind method for planting and output have great significance to national economy.For many years, traditional ridge culture planting method, the income that is restricting maize yield and peasant that this is serious are still adopted in most areas.Majority think that maize yield has arrived the limit, even also have the many ways to fertilize of many people employing blindly, but how much output do not improve, on the contrary because a large amount of chemical fertilizer that uses, soil is hardened year by year, make the salinization of soil, the humus in the soil also reduces year by year.Above problem is now paid attention to by many experts, and the proposition agricultural systems engineering is solved.The present invention utilizes system engineering exactly, comprehensive, the comprehensive resource and the corn planting yield-increasing technology of a kind of uniqueness of inventing in conjunction with the various agricultural technology of utilizing.

Available following 24 the word general description of this invention of summary of the invention: promptly adopt the duplicate rows overlay film; Rational close planting; Drip irrigation at the bottom of the film; The interlacing crop rotation; Toothing is increased soil fertility; No-tillage minimal tilling; Comprehensive land used (auspicious see accompanying drawing).

The duplicate rows overlay film is exactly films of per two row buttons, and the purpose of overlay film is to improve ground temperature, prevents water evaporates, even run into the days of arid, also can keep soil moisture content, and it is strong to reach Miao Qimiao.

Present technique adopts the way of interlacing crop rotation, such as kind odd-numbered line (promptly 1,3,5,7,9 in this year ... OK), even number line is lain fallow; Just plant even number line (promptly 2,4,6,8,10 next year ... OK), odd-numbered line is lain fallow, the plantation in turn of odd-numbered line, even number line, and be not simple crop rotation, but the mode that adopts toothing to increase soil fertility.Such as odd number behavior plantation in this year row, when gathering in the root stubble is stayed in the soil to autumn, just even number line will be decided to be the plantation row next year, root stubble through the year odd-numbered line has just rotted, become the humus useful, become the fertilizer of 1 year crop, can plant in the above crop.So, always there is delegation alternately lying fallow in two row, cultivates humus.Go down for a long time, soil is more and more fertile, and the soil fertility of having fostered and apply fertilizer can reduce using of chemical fertilizer year by year, and this is the measure that long-range economic benefit and social benefit are arranged.Because the root stubble is the darkest to be reached more than half meter, it makes soil become very soft after rotting, and can directly sow in the above, and need not tillage operation in 1 year.

In addition,, in time execute water, make crop obtain sufficient moisture, impel plant growth, reach the purpose of increasing both production and income to crop by drip irrigation at the bottom of the film.

This kind of method for planting, first, 2 years, can put in order ground, later on can not need carry out tillage operation.Because overlay film is arranged, weeds do not have the condition of existence, add the use of weed killer herbicide, just need not intertill, and the rotten root stubble soil that loosened again need not be put in order ground before broadcasting, and has reduced peasant's labour intensity, has saved farming season and peasant's financial burden.Because need not put in order ground, promptly no-tillage, minimal till, that has reduced farm machinery advances the ground number of times, makes soil not harden, reduce tillage pan, and this also helps the growth of crop.

Owing to adopt the interlacing crop rotation, strengthened the distance between plant row and the row, be 65cm as original spacing in the rows, adopt interlacing crop rotation spacing in the rows to become 130cm, strengthened draught area.Simultaneously, because line-spacing is wide, the sunshine condition that plant is subjected to has also improved, and these two have guaranteed that also corn yield increasing increases income.

The another one characteristics of present technique are rational close planting, and its spacing in the rows becomes 0.5 chi-0.6 chi by traditional 1 chi-1.2 chi, but such planting density guarantor unit output is doubled above.

So-called comprehensive land used, i.e. cultivated mushroom in the furrow under film, the comprehensive utilization farmland, this is again peasant's a income.

In sum, this corn planting volume increase new method has adopted new technologies and methods, and corn all is in whole growth process under the optimal conditions, impels corn yield increasing, and the general land measure equal to fifteen mu in most parts of the Northeast produces and can reach more than 1700 kilograms.

Four ridges of drawing in the description of drawings illustrate, for ease of operation with to adapt to film wide, the plastic film in upper berth, per two ridges is so be called " duplicate rows overlay film ".Be equipped with drip irrigation pipe under the plastic film, be used for executing water and irrigate i.e. " drip irrigation at the bottom of the film " to crops.As we can see from the figure, lie fallow a ridge or a plantation ridge (ridge of lying fallow, plantation ridge replace every year) are just arranged in the four lines in every line, on the platform of the ridge on the ridge of lying fallow, leave the corn stubble of the previous year, this root stubble was through 1 year rotted, when this ridge became the plantation ridge in 1 year, its root stubble that rots just becomes the fertilizer of crop (maize seedling), Here it is above-mentioned " interlacing crop rotation " and " toothing is increased soil fertility ".

Embodiment adopts this technology that the water source must be arranged, general available way of beating motor-pumped well or with other ways solutions.The available artificial or mechanical way of the installation of spray irrigation pipe all can at the bottom of overlay film and the film.Corn planting adopt sower or manually all can, but necessarily note dense planting and crop rotation, necessarily the root stubble is stayed in the soil other no specific (special) requirements when gather in autumn.

Claims (3)

1, interlacing alternating method just has the row of lying fallow in every line, has promptly strengthened the row spacing of crop relatively, improves to ventilate and sunshine condition.

2, toothing is increased soil fertility, and the root stubble of lying fallow capable is retained in the soil, through 1 year rot, becomes humus, becomes the nutrient of the maize seedling in 1 year.

3, drip irrigation, interlacing crop rotation, toothing are increased soil fertility, are no-tillagely minimal tilled at the bottom of duplicate rows overlay film, rational close planting, the film, multiple technologies such as comprehensive land used comprehensively use.
