Abstract
The present invention relates to active calcium fertilizer which belongs to a soil adjusting material or a soil stabilizing material. The present invention contains 65 to 85% of shell powder, and the sum of magnesium containing substances and sulfur containing substances occupies 15 to 32.7%. The present invention is separated from marine organisms, can rapidly change the ecological environment of soil after fertilized in the soil in an undefiled way and is favorable for plant growth. Plants have the advantages of forceful plant shapes, firm stems, strong leaves and strong lodging resisting and plant disease and insect pest resisting capability after the present invention is used by the indication of vegetable, fruit tree and field crop experiments, and the present invention can also activate microelements, such as nitrogen, phosphorus, potassium, etc. in the soil and can be easily absorbed by the plants; meanwhile, the increase of nitrate and nitrite in the soil is eliminated and restrained, the secondary salinization is reduced, and the present invention prevents the soil from agglomerating.
Description
The present invention relates to a kind of fertilizer.
Along with the soil uses year after year, the nutrient in the soil is caused soil acidityization by crop absorption, and calcium-magnesium content reduces.For improving soil quality, people often adopt the method that limes Tanaka, in order to improve the pH value of soil.Because lime powder alkalescence is stronger, very easily makes soil block and be unfavorable for the growth of plant.
The objective of the invention is to: disclose and a kind ofly effectively improve soil quality, improve its pH value and can not make the active calcium fertilizer of soil block.
We find after deliberation, contain a large amount of calcium oxide and a spot of magnesium oxide and other trace element in the shell.Wherein the content of calcium oxide is about 53.34%, and magnesian content is 1%, also has 24 kinds of elements such as silicon, iron, aluminium, potassium, sodium, phosphorus in addition.That is to say that it contains the needed a large amount of mineral substance of improving the soil.There is very long shoreline in China, and abundant shell ore resources is arranged, and this provides advantageous conditions for enforcement of the present invention.
According to the requirement of soil improvement, the ratio of the pleasant to the ear calcium-magnesium content of fertilizer should also should contain an amount of sulphur in addition about 4: 1.Therefore, active calcium fertilizer of the present invention generally contains oyster shell whiting 65-85% in being, contains the magnesium material, the sulfur material sum accounts for 15-32.7%, also can add other material as required in addition.Oyster shell whiting wherein can directly be pulverized by shell and make, and also can be the 40-100 order powder of shell ore deposit through pulverizing, going soil to make through weathering in thousand forms.Active calcium fertilizer of the present invention is the fertilizer that obtains with the marine organisms shell, is a kind of pollution-free, non-harmful fertilizer.It contains the required calcium of soil, magnesium, sulphur and various trace elements, and wherein a part is in active condition.Can change the ecotope of soil after being manured into soil rapidly, help plant-growth.Show that by the experiment to vegetables, fruit tree, field crop behind use the present invention, plant strain shape is tall and straight, the hard leaf of stem is perpendicular, and resistant to lodging, diseases and insect pests resistance enhancing.For example the rice blast sickness rate can reduce by 50%, disease and pest index decreased 0.12-0.15, and the rice root decomposing disease descends 80%, and peanut and rape oleaginousness improve 10%, and fruit quality, local flavor obviously improve.It can also activate trace elements such as nitrogen in the soil, phosphorus, potassium, and it is easy to by plant absorbing, eliminates and suppress the growth of nitrate in the soil, nitrite simultaneously, supports the secondary salinization effect, prevents soil block.
By the following examples the present invention is elaborated.
Embodiment two:
Magnesium oxide more than 95% of oyster shell whiting, purity, purity sulphur or the sulphur powder more than 95% mixed by 85: 13.67: 2.4 weight ratio and stir and make finished product.By analysis, wherein contain (in by weight of fertilizer) calcium 32.3%, magnesium 8.07%, sulphur 2.3% also contains other the 24 kinds of trace elements in the oyster shell whiting.Wherein calcium magnesium nutrition element wt ratio is 4: 1.This finished product is applicable to that pH value uses at the soil below 6.5.
Embodiment two:
Oyster shell whiting, purity magnesium oxide, the sulfuric acid of concentration more than 95% more than 95% is mixed by 80: 12.88: 7.12 weight ratios, and the back drying that stirs is made and is contained calcium sulfate, calcium oxide, sal epsom, magnesian mixture.By analysis, it contains (in by weight of fertilizer) calcium 30.4%, magnesium 7.6%, and sulphur 2.32% also contains other the 24 kinds of elements in the oyster shell whiting.Wherein calcium magnesium nutrition element wt ratio is 4: 1.This finished product is applicable to the soil of pH value between 6.5-7.5.
Embodiment three:
With oyster shell whiting, sal epsom (sal epsom purity is more than 95%) and contain the molybdenum raw material and the boracic raw material is made finished product after mixing by 65%, 32.7%, 1.3% and 1%.Wherein the boracic raw material can be boric acid, and the raw material that contains molybdenum is a normally used raw material in the chemical fertilizer industry.By analysis, wherein contain (in by weight of fertilizer) calcium 24.7%, magnesium 6.17, sulphur 6.6%, molybdenum is about 1.3%, and boron is about 1%, also contains other the 24 kinds of elements in the oyster shell whiting.Wherein calcium magnesium ratio is about 4: 1.This finished product is applicable to planting vegetable in greenhouse.
