Abstract

The invention provides a high-temperature land boiling soil recuperating method resisting continuous cropping. The high-temperature land boiling soil recuperating method resisting the continuous cropping is low in cost, easy to operate, multifunctional, practical, and effective. The high-temperature land boiling soil recuperating method resisting the continuous cropping includes in a fallow period of a summer greenhouse, taking full advantage of the natural environmental conditions of the continuous high temperature and the strong ultraviolet radiation, artificially creating a sealing anaerobic environment in the greenhouse, processing soil and recuperating the soil. The soil recuperating method is low in cost, strong in operability, has five functions including a sterilization, salt-leaching (salt-reducing), moisture generating, nematode killing, and soil microflora recuperating and balancing, avoids that a large amount of medication generates secondary damage to the soil, has an obvious ecological effect, and fits in with the sustainable development of production of melon, fruit and vegetable in greenhouse protected areas under the situation of China at the present stage very much.

Description

The anti-continuous cropping soil Opsonizing method in a kind of high-temperature boiling field

Technical field

The present invention relates to the anti-continuous cropping soil Opsonizing method in a kind of high-temperature boiling field.

Technical background

soil is the basic condition of plant growth, the growth and decline of various nutritive elements in soil, in soil solution environmental change and soil, the balance of various microbiologic populations is all dynamic change along with the carrying out of mankind's farming activities, thereby, soil is also as the human lives, gap in one batch of stubble farming " work ", the process that a rehabilitation fully and conditioning must be arranged, and our country due to national conditions and present stage development level restriction, can't can implement strict Fallow crop rotation system with the form of legislation as European and American developed countries at present, continuous cropping phenomenon between continuous cropping and equal crop even of the same race also is difficult to avoid to a certain extent, the evils that soil continuous cropping obstacle brings also are difficult to eradicate to a certain extent.But this does not mean that we just can not take this objective ecological rule into account, and increase the weight of arbitrarily and without limit the burden in soil, thereby must be under the principle that can hold sustainable development, take the practicable measure that tallies with the national condition, adopt an effective means on the use and maintenance of soil and accomplish something.

During China vegetables produce at present, booth Protected production scale is increasing; and how progressively formed to delay as main stubble, spring precocity and autumn take the autumn and delayed the cropping system of doing in a year two; and the continuous cropping between equal crop is also more general; the harm that continuous cropping obstacle brings becomes gradually vegetables and produces a great problem that further develops; to the early 1990s in last century; soil salt marsh evil in booth ground is more obvious, and root-knot nematode is once rampant and be and spread development trend.Annual May is after late June, spring stubble booth ealy maturing culture vegetables are pulled out successively straw and rise stubble, until before the autumn before and after mid-August delays crops for rotation and begin, generally have a summer fallow phase of lasting about 2 months, the invention provides a kind of method that this section phase of lying fallow nurses one's health soil of utilizing.

Summary of the invention

The invention provides a kind of soil conditioning method of low cost, easy to operate, multi-functional and practicability and effectiveness: the anti-continuous cropping soil Opsonizing method in high-temperature boiling field.Namely at summer fallow in the phase, take full advantage of the natural environmental condition of this time period continuous high temperature and strong ultra-violet radiation, the artificial environment of creating a closing anaerobic in the booth field is implemented to process and conditioning to soil.

Implementation process of the present invention is as follows:

The anti-continuous cropping soil Opsonizing method in a kind of high-temperature boiling field comprises the following steps:

(1) pull out straw and rise stubble: the booth field that the spring stubble was gathered in the crops is carried out the tangerine bar and is pulled out, the residual branch in cleaning earth's surface

Fallen leaves, and take canopy out of and process outward;

(2) the vexed canopy of high temperature: close booth and tan by the sun 3-5 day;

(3) deep ploughing surrounding edge: furrow soil in booth is implemented deep ploughing, then continue to close and tan by the sun some days under canopy or the outdoor state after unloading film, then take field as the unit, shallow ridges at the dark 25-30cm of surrounding digging, place one with the plastic film of wide 30-40cm along the ditch outside again and enclose and return the soil pressure reality, prevent that water in field from leaking outside;

(4) layer is protected in water filling: select the continuous high temperature fine day, to enclosing water filling in good field, make the thin water layer that forms 10-15cm in field, and kept thin water layer 7-10 days;

(5) breath water is rested: after shoaling layer is kept 7-10 days, allow water layer naturally cease and do, keep static recuperation, until basal dressing rotary tillage before multiple stubble.

Principle of the present invention is: in the vexed canopy stage of high temperature, utilize nature high light and continuous high temperature to kill the harmful germ in earth's surface; The layer stage protected in water filling, continues under natural high light and continuous high temperature condition, kills harmful germ and root-knot nematode in topsoil by the closing anaerobic environment of artificial creation, reaches simultaneously the multiple-effects such as the desalinization of soil by flooding or leaching, salt reduction and moisture creating; Breath water is rested the stage, keeps gentle soil environment state, facilitates the growth and breeding of the useful thing of supporting one's family of soil and the balance conditioning of microbiologic population.

The present invention has the following advantages:

The way of soil conditioning provided by the invention, cost are very cheap, and ease for operation is strong, sterilization is arranged, wash (falling) salt, moisture creating, kill nematode and take good care of five large effects such as balance soil microbial community.

Embodiment

Embodiment

(1) pull out straw and rise stubble: the booth field that the spring stubble was gathered in the crops is carried out the tangerine bar and is pulled out, the residual branch in cleaning earth's surface

Fallen leaves, and take canopy out of and process outward;

(2) the vexed canopy of high temperature: close booth and tan by the sun 3-5 day;

(3) deep ploughing surrounding edge: furrow soil in booth is implemented deep ploughing, then continue to close and tan by the sun some days under canopy or the outdoor state after unloading film, then take field as the unit, shallow ridges at the dark 25-30cm of surrounding digging, place one with the plastic film of wide 30-40cm along the ditch outside again and enclose and return the soil pressure reality, prevent that water in field from leaking outside;

(4) layer is protected in water filling: select the continuous high temperature fine day, to enclosing water filling in good field, make the thin water layer that forms 10-15cm in field, and kept thin water layer 7-10 days;

(5) breath water is rested: after shoaling layer is kept 7-10 days, allow water layer naturally cease and do, keep static recuperation, until basal dressing rotary tillage before multiple stubble.

Facts have proved; the booth field of using method provided by the invention to process; the sick worm radix of lower stubble obviously reduces; Soil Secondary salt marsh evil is significantly alleviated; root-knot nematode is almost solved at all; avoid simultaneously the secondary injury of high amount of drug processing to soil, significant ecological effect has been arranged, be fit to very much the sustainable development that the booth protection digua fig fruit vegetables under the present stage China's national situation produce.
