Abstract

The invention relates to a method for soil sterilization and deinsectization by jetting steam, which comprises the steps of generating high-temperature and high-pressure steam through a heat vaporization method by using clean water on an agricultural machine such as a soil turning machine or a soil loosening machine, and then jetting and injecting the high-temperature and high-pressure steam into soil through a movable jetting arm when equipment turns or loosens the soil to realize the sterilization and deinsectization treatment of the soil through the high-temperature steam. By using the high-temperature steam to kill bacteria, injurious insect eggs, young insects and weed seeds and seedlings, the healthy growth of crops is promoted. Since chemicals are not used, soil pollution and environmental pollution are not caused, and the method is a clean and environmentally-friendly soil treatment method. The method can realize soil sterilization treatment at the same time when the soil is turned, the efficiency is greatly improved, and the method is suitable for working on large-area farmland.

Description

A kind of method that adopts uperize to carry out the soil sterilization deinsectization

Technical field the present invention relates to the method for a kind of soil sterilization deinsectization of agricultural technology field.

Background technology is cut the earth, is loosened the soil, sterilization, deinsectization and weeding all are necessity work of agricultural tillage process, be conducive to increase gas permeability of soil energy by cutting the earth and loosening the soil, accelerate soil-ripening, improve the feeder capability of soil, promote crop growth, and can kill a part of insect.Disinfection and deinsectization is conducive to kill bacterium and the insect in the soil, reduces the damage by disease and insect of crop.Weeding is conducive to reduce the invalid loss of nutriment in a fertilizer, safeguards crop growth environment.In existing technology; the disinfection and deinsectization aspect generally adopts the chemical agent sterilization that carries out disinfection; such as formalin, carbendazim, zineb, potassium permanganate etc.; the weeding aspect generally is to adopt the weed killer herbicides such as weeding is logical, Amex820, Lonster, the spirit of drought grass; although these methods produce effect; but use for a long time these chemicalses obviously can to environment, without being beneficial to environmental protection, also can make the characteristic variation of soil.Although and the environmental protection such as poach, stir-fry soil, fire are roasting, film sterilization, Boiler Steam bactericidal assay, but treatment effeciency is low after all, be only suitable for processing the soil of small amount, such as the Nutrition Soil processing that is used for Floristry etc., and be not suitable for carrying out soil treatment in large-area arable land.

Summary of the invention purpose of the present invention is to disclose a kind of do not need to use chemical agent and the suitable soil sterilization deinsectization method that uses on large tracts of land is ploughed.

Method of the present invention is: on the motor device of rooter or loosenning tiller, adopt clean water to produce high temperature and high pressure steam by the mode of heat vaporization, in the action of digging or loosening the soil of equipment, simultaneously the spray arm of high temperature and high pressure steam by activity sprayed again and be injected into the soil the inside, by high-temperature steam soil is carried out disinfection and deinsectization and process.

The production method of described high temperature and high pressure steam comprises and adopts gasoline or diesel oil to act as a fuel, and produces heat energy by burner, in vaporizer water vapor is produced high temperature and high pressure steam again.

Soil sterilization deinsectization method of the present invention, when adopting rooter that arable soil is digged, the high-temperature high-pressure steam injection is injected into the soil the inside, seed and seedling by high-temperature steam kill bacteria, worm's ovum, larva, weeds, reach the effect of sterilization, weeding and desinsection, promote the healthy growth of crops.Because the course of work only uses clean water, and without any need for chemical agent, so can not cause any pollution to soil and environment, also can not leave over any chemical residue crop, be a kind of agent, soil treatment method of the most clean, sanitary, environmental protection.And the present invention is arranged on steam generator on the rooter, realizes that when digging soil sterilization processes, and both obtained better disinfection and deinsectization effect, also greatly raises the efficiency, and is fit to use plough in large tracts of land carry out the soil sterilization deinsectization.

Embodiment is following to be one embodiment of the present of invention.

On common rooter, other is provided with water tank, water pump and steam generator, steam generator includes and adopts metal material processing and the combustion chamber that is bound up and vaporizer, adopt gasoline or diesel oil to act as a fuel during work, produce heat energy by burner, be delivered in the vaporizer, water pump pumps into the water of water tank the inside in the vaporizer of steam generator, and the instantaneous vaporization of being heated in the vaporizer the inside produces high temperature and high pressure steam.

Be provided with in addition one group of branched steam spray arm in the mechanism of digging of rooter, the steam spray arm is with rooter the dig action of mechanism and synchronous rotary, and compartment inserts by in the arable soil that rooter climbed over along with rotation.With the steam jet blower, and be connected to the steam output end mouth of steam generator on each steam spray arm, when the steam spray arm inserts soil, open simultaneously valve high temperature and high pressure steam is injected into the soil the inside by nozzle ejection.Because the vapor (steam) temperature injected is very high, can moment the larva of the seeds of the bacterium of arable soil the inside, weeds, insect and worm's ovum etc. be killed, reach purpose of the present invention.

Because the present invention and original rooter technology are used in conjunction with, when digging, steam in time sprayed and be injected in the soil that climbs over, so can either obtain better disinfection and deinsectization effect, and one action finishes simultaneously just and digs and disinfection and deinsectization work, improved operating efficiency.

Claims

1. method that adopts uperize to carry out the soil sterilization deinsectization, it is characterized in that on the farm machinery of rooter or loosenning tiller, adopt clean water to produce high temperature and high pressure steam by the mode of heat vaporization, in the action of digging or loosening the soil of equipment, simultaneously the spray arm of high temperature and high pressure steam by activity sprayed again and be injected into the soil the inside, by high-temperature steam soil is carried out disinfection and deinsectization and process.

2. a kind of method that adopts uperize to carry out the soil sterilization deinsectization according to claim 1, it is characterized in that: the production method of described high temperature and high pressure steam, comprise and adopt gasoline or diesel oil to act as a fuel, produce heat energy by burner, in vaporizer, water vapor is produced high temperature and high pressure steam again.
