The saltiness of soil is the saltings 3 ‰, and surpassing 6 ‰ is the severe saltings.The pH value of moisture surpasses 8.5 in the heavy salinized ground soil, causes soil compaction, and the root system of crop is also had restraining effect, restricts crop and does not grow or grow unhealthy.In heavy salinized ground, the farm crop seedling rate is lower than 50%, and the farm crop that emerge also are in the situation of low yield or total crop failure.
At present to the improvement in saltings with utilize method to focus on and improve water regime of soil, generally divide several steps to carry out.At first salt discharge, the desalinization of soil by flooding or leaching, reduction soil salt content; Next plants the plant of salt tolerant alkali, fertilizing soil; Plant plant at last.This method cycle is long, and the cost height is difficult to quickly and efficiently the big area alkaline land soil be improved.Some are added on the auxiliary preparation of improving the soil in the fertilizer, also because of reasons such as its raw material is difficult to obtain, complicated process of preparation cause cost too high, are difficult to promote.
Summary of the invention
Main purpose of the present invention provide a kind of with low cost, make it to be suitable for the particularly fertilizer of crop growth of plant with being used for transformation salinity.
To achieve these goals, the present invention is by the following technical solutions:
A kind of fertilizer that is used for transformation salinity ground is made up of the lightweight shale opal of 2-8 weight part, the humic acid of 2-8 weight part and the fertilizer of 0-2 weight part.Described fertilizer can be that agricultural goes up the conventional human and animal excreta that uses, plant and animal residues, animals and plants meta-bolites, organic matter fermentation product etc.
Described fertilizer preferably is made up of the lightweight shale opal of 4-8 weight part and the humic acid of 2-6 weight part.
The granularity of described lightweight shale opal is the 20-1000 order.
The granularity of described lightweight shale opal is the 200-800 order.
Described humic acid is brown coal.
The granularity of described brown coal is the 20-1000 order.
The granularity of described brown coal is the 200-800 order.
Beneficial effect of the present invention is:
In the component of fertilizer of the present invention, the lightweight shale opal element constitutes abundant, and has very strong adsorptive power; Humic acid is the natural organic fertilizer material, contains the necessary multiple element of plant-growth, and the root system of plant of enhancing intensity, the effect of building up resistance are arranged.The two is used in combination, and can provide plant-growth necessary nutrient, and can improve the alkaline land soil composition simultaneously, reduces salt content, increases soil fertility.
The component lightweight shale opal of fertilizer of the present invention and humic acid are all very high, cheap in China's output, and it is convenient to obtain; And fertilizer technology of the present invention is simple, easy to prepare, and therefore whole cost is lower, is easy to promote.
Embodiment
The composition that is used for the fertilizer on transformation salinity ground of the present invention the be weight percentage lightweight shale opal of 20-80% and the humic acid of 20-80%.Be preferably the lightweight shale opal of 40-70% and the humic acid of 30-60%.
In the component of fertilizer of the present invention, lightweight shale opal is chosen the opal that originates from the domestic albumen shale ore in Inner Mongol Mo Qi E Er and township, evaluation is analyzed and made to the lightweight shale opal of this area's output through Heilongjiang Province bureau of geology and mineral resources, prove that its material is good, of high grade, adsorptive power is strong.The humic acid that the present invention adopts is not limited to any form, waits the depth of humus layer that forms more convenient at aspects such as processing, storage, transportations because brown coal are fallen leaves, so preferred brown coal are as raw material of the present invention.Adopt the brown coal of Huo Lin river coal field output in the present embodiment, higher because of the brown coal content of humic acid in this mining area, be more suitable for plant-growth.
Lightweight shale opal of the present invention and brown coal are processed to granularity and all can use at 20-1000 purpose powder, are preferably granularity at 200-800 purpose powder.The following fertiliser granulates of 20 orders can not be a crop utilization well, and it is then unnecessary to be processed into thinner powder.
