The herbicide of 400-7000ppm.
Further, the chemical fertilizer is ammonium bicarbonate, ammonium nitrate, phosphate fertilizer or a variety of mixtures.
Further, the fungicide and a certain amount of defoaming agent of aqueous solution quality 40ppm are added in the aqueous solution of configuration, so
After be sprayed at soil surface.
Further, the water used when configuring aqueous solution is tap water, river water or rainwater.
Water soluble polymer agricultural land soil hardening resisting agent of the invention includes water-soluble high molecular material and in water solubility
A small amount of crosslinking agent is added in masterbatch, after high molecular material chemical structure soluble easily in water and crosslinking agent reaction, in water
Tridimensional network is formed in solution, soil hardening resisting agent is dissolved in water, is sprayed in farmland, in soil surface and centainly
Depth in form a tridimensional network, form certain space between soil particle, effectively prevented soil
Aggregation between particle.
The compound surfactant of quality 0.05%-0.1% is added in water-soluble high molecular material, mainly at
It is divided into zwitterion compound surfactant, effectively prevents the aggregation of moieties electrically charged in soil, further to anti-
Only soil hardening.
Add water to be configured to the aqueous solution that mass concentration is 0.2-1.5% soil hardening resisting agent when use and is sprayed at soil table
Face；Or come temporarily, soil hardening resisting agent powder to be uniformly sprinkled upon soil surface in the rainy day；It can be according to farmland and crop
The chemical fertilizer of aqueous solution quality 100-500ppm, aqueous solution quality 400-7000ppm are added in actual demand in the above system
Herbicide, in addition to can effectively prevent the aggregation of moieties electrically charged in soil, so that it is outer to keep soil from packing together, Shang Neng
The effect of playing slow release chemotrophy and slow release herbicide, inhibiting the growth of weeds.
The fungicide and a certain amount of defoaming agent of aqueous solution quality 40ppm can also be added in the aqueous solution of configuration, prolong
Long shelf-life, when use, are sprayed at soil surface again.
Agricultural land soil hardening resisting agent of the present invention, formula are mainly used in the soil hardening in Arid&semi-arid area rural area field
Problem, and all raw materials used belong to green material, play soil in crop growth and Chinese medicine growth course
The anti-hardening function of earth, the soil hardening resisting agent during use, can be degradable to be nontoxic the 8-12 middle of the month
Small molecule material, and the small molecule that can be absorbed as crop can be degraded to and be absorbed by plants, safety and environmental protection is nuisanceless, right
Soil and environment will not generate any pollution.
The water used when configuring aqueous solution is tap water, river water or rainwater, gathers materials on the spot and solution allocation can be completed, and is used
It is convenient and simple, it can promote the use of a large area.
Chemical fertilizer and herbicide are added in soil hardening resisting agent formula, in the spraying operation of farmland, one-stop operation is played
Multi-efficiency reduces the difficulty and intensity of construction, has saved cost, improved efficiency.
