Description
Technical field
The present invention relates to weeding technique fields, and in particular to a kind of green house of vegetables high-efficiency environment friendly herbicidal methods.
Background technique
Green house of vegetables is a kind of frame structure of film with outstanding thermal insulation property, it occurs that people are had
Vegetables in improper season.General green house of vegetables is covered with one or more layers insulating plastic pipe using bamboo structure or the skeleton of steel construction above
Film, material is thus formed a greenhouse spaces.Outer membrane prevents the loss of carbon dioxide caused by internal vegetable growth well,
Make that there is good heat insulation effect in canopy, greenhouse gardening vegetables are that have very big economic benefit, while also improving people's
Quality of life, in order to improve the quality of booth vegetable, farmer constantly improves the greenhouse of oneself.
The weeds left are FAQs during planting vegetable in greenhouse when crop is changed crops in green house of vegetables, using manually removing
Grass is at high cost, directly turns over and brings difficulty to small-size rotary tiller operation, be easy to cause soil again using herbicide chemical weed control
Middle pesticide residue and season crop-planting after influencing.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of green house of vegetables high-efficiency environment friendly herbicidal methods, on solving
State the problem of proposing in background technique.
The present invention solves technical problem and adopts the following technical scheme that
The present invention provides a kind of green house of vegetables high-efficiency environment friendly herbicidal methods, comprising the following steps:
(1) crop is changed crops period, is selected successive clear days 2~3 days, according to every 666.7m2Greenhouse applies 12.5 kilograms of agricultural carbon
Sour hydrogen ammonium, spreads fertilizer over the fields from greenhouse center toward canopy doorway, and full canopy is sealed after the completion of spreading fertilizer over the fields, is added with ammonium hydrogen carbonate in agricultural ammonium bicarbonate
The concentration aggregating agent of total amount 5-10%, the mixing that the concentration aggregating agent is magnesium sulfate, sodium chloride is formed according to weight ratio 2: 1
Object；
(2) it after weeds are withered, pours water in greenhouse, absorbs extra ammonia, canopy use can be opened within second day after pouring water.
Preferably, 2~3 days canopy temperatures of the successive clear days reach 40 DEG C or more.
Preferably, it is described spread fertilizer over the fields during ammonium hydrogen carbonate is uniformly spread fertilizer over the fields to the soil surface in greenhouse
Preferably, the fountain height poured water is 6.0Kg/m2。
Preferably, contain nano-stephanoporate silicon dioxide in the water of the spraying gun spray outlet.
Preferably, the aperture 15nm of the nano-stephanoporate silicon dioxide, specific surface area 280mm2/g。
The action principle of ammonium hydrogen carbonate
1, ammonium hydrogen carbonate is the carbonate of ammonia, molecular formula NH4HCO3, it is used as chemical fertilizer nitrogenous fertilizer, is suitable for various soil
Earth, ammonium nitrogen and carbon dioxide needed for can providing simultaneously plant growth, can promote plant growth and photosynthesis, urge seedling long
Leaf can make top dressing, can also make base fertilizer and directly apply.
2, the unstable chemcial property of ammonium hydrogen carbonate is heated and easily decomposes, and 35 DEG C or more are decomposed into ammonia (NH3), water (H2O)、
Carbon dioxide (CO2), 60 DEG C can thoroughly decompose completion.Chemical equation are as follows: NH4HCO3==heating==NH3↑+H2O+CO2
↑.This property is easily decomposed using ammonium hydrogen carbonate is heated, ammonium hydrogen carbonate is placed in green house of vegetables, greenhouse is sealed.
3, the characteristic of ammonia: having special ammonia odor taste, and the ammonia of low concentration will not injure plant and can be absorbed by plants,
Being conducive to plant growth as nitrogen nutrition, high concentration ammonia will affect plant leaf blade and acute injury occur, and mesophyll tissue collapses,
Chlorophyll disintegrates, and a large amount of high concentration ammonias will lead to plant quick death.
Compared with prior art, the present invention have it is following the utility model has the advantages that
In the actual production process, we have invented using agricultural ammonium bicarbonate herbicidal methods, using ammonium hydrogen carbonate by
Thermally decompose the ammonia weeding generated, reach that herbicidal effect is good, at low cost, easy to operate, pollution-free, noresidue, be it is a kind of both efficiently
Ammonium hydrogen carbonate, is uniformly spread fertilizer over the fields the soil surface in greenhouse, ammonium hydrogen carbonate is being decomposed by the herbicidal methods of environmental protection again during spreading fertilizer over the fields
It can directly be contacted first with weeds cauline leaf in the process, leading to weeds, nearby oxygen content is greatly lowered, and then accelerates weeds dead
It dies, magnesium sulfate, sodium chloride can decompose ammonium hydrogen carbonate early period and inhibit in the concentration aggregating agent of ammonium hydrogen carbonate addition, but carbonic acid
Hydrogen ammonium decomposition total amount is constant, and as the resolving time increases, mid-term and later period a large amount of ammonia aggregation, high concentration ammonia accelerate plant
Quick death sprays spray water using spraying gun in water-pouring process, and the contact area of water and ammonia can be improved, and accelerates ammonia and inhales
It produces effects rate, the porous nano silica effect added in water, one is being improved because its high-specific surface area can be used as the carrier of water
Water is compatible on its surface with ammonia, accelerates absorption efficiency, secondly ammonia and water, which are formed system, is stored into porous nano titanium dioxide
In the gap of silicon, the slow release in subsequent vegetable growth improves plant growth efficiency.
