Abstract

The invention is made by utilizing high-calcium low-graded phosphorus ores which are disused at present to be pulverized directly and then be added with the raw material such as boiling shales and rare earths which is needed during plant growing process, and is used for the acidity-alkalinity neutralization and the soil fertility increasing in large acid soils in the southern China so as to lead teaks to normally grow according to the basophilous characteristic of the teaks. The invention belongs to the scientific utilization of the low-graded phosphorus ores which are abandoned at present and have no roasting, no manual acid hydrolysis, low energy consumption and no pollution. The invention is the special neutralizer and fertilizer with low cost and high efficiency used by the teaks and basophilous plants in acid soils.

Description

Teak special-purpose soil pH value neutralizing agent mixing boiling fertilizer and production method

1, technical field

Teak is the unique precious timber of determining the price with jin in the world, and the existing international price of one-level material reaches whenever wet ton Renminbi more than 60,000 yuan, and it is happiness alkali and " three height "---(high temperature, Gao Shui, high fertile) plant only adapts to China's very low range plantation under the natural condition.The exploration of inventor by about ten years, by a series of innovations with teak in the Guizhou successful introduction, this has just created precedent for these high-grade timber of ground establishing in large scale such as Guangdong, Guangxi, Fujian, Hainan that heat quantity of precipitation is higher than Guizhou.But, except that natural heat and quantity of precipitation satisfy the requirements, improve local soil acidity or alkalinity and just become key because these areas mostly belong to acid soil.

2, technical background

2.1 tradition is easy, way is that sour earth is applied lime neutralizing acid basicity cheaply, but becomes stone owing to be reduced to the lime carbonate of insoluble in water after lime chance water and the acid again, causes the hardening soil and soil and lime to change with fixed attention when reducing soil acidity; Add the big bulge in price of coal, electricity, oil in recent years, the production cost of lime is doubled and redoubled, and it is rotten that lime powder chance water promptly produces reaction, both inconvenient accumulating, and also validity period is of short duration.Add that lime only is acid neutralizing agent, do not have how many fertilizer efficiency, seldom adopt,, need a kind of neutralizing agent more better than Wingdale in the high area development teak plantation of soil acidity or alkalinity with lime improvement acid soil.

2.2 the Rock Phosphate (72Min BPL) of China 80% is " phosphorite ", and the phosphorite in Guizhou removes Vanadium Pentoxide in FLAKES (P ₂O ₅) main calcic, aluminium, magnesium, iron and harmful element fluorine.In the production technique of common phosphate fertilizer, mainly be by acid water-fast phosphorus to be decomposed into molten water phosphorus to supply plant absorbing.Because calcium, magnesium, aluminium, iron are being taken away partly phosphorus with fixed attention with the acid Shi Douhui that reacts, still the phosphorite phosphorus content of state is passed into disuse substantially at the low grade ore below 26%, and this part low grade ore surpasses more than 60 percent in the total reserves of Guizhou phosphorus ore, partly the utilization (commercial value) of resource is unresolved always to this, causes great waste and has increased the production cost of mining and finished product fertilizers.

3, summary of the invention

The present invention is according to " phosphorite " loosely organized porous, it is big to reveal the surface, the easy principle of being decomposed by acid, it is 120 purpose breezes (Chemical Manufacture phosphate fertilizer is generally 80 orders) that existing " phosphorite " of Chemical Manufacture phosphate fertilizer below the low phosphorus ore (phosphorous 26 °) of waste direct mill after mud is removed in washing is beaten, and according to the growth demand of teak be mixed other fertilizer and element, directly to planting teak in acid soil as potential of hydrogen neutralizing agent and base manure.When ground phosphate rock with soil in acid when reacting, play three kinds of effects: the one, neutralizing acid reduces soil acidity; The 2nd, with insoluble in water ground phosphate rock, be decomposed into solvable water phosphate fertilizer for plant absorbing; The 3rd, the heat that sour phosphorus distributes when chemically reacting and a large amount of gas can improve ground temperature, are beneficial to plant root growth and microbial reproduction, impel the soil loose.

Because ground phosphate rock is the acid generation reaction by soil, the soil moisture and humidity directly influence its decomposition and discharge, and this reaction is slower, and the long forest of suitable growth cycle mainly is the plantation on acid soil of teak and basophilous plant.Add that forest dry-matter accumulation (long thick) mainly absorbs things such as airborne ammonia, nitrogen and changes by photosynthesis.The inventor can facilitate organic decomposition and increase the principle that plant is changed absorption, screening, the acceleration of thing such as ammonia, nitrogen in the air according to adsorptivity, screening property and the ion exchangeable etc. of zeolite, increase the zeolite that accounts for total composition 1 15 again, be teak special-purpose soil pH value neutralizing agent mixing boiling fertilizer so this fertilizer is named.

4, implementation method (production technique)

4.1 mud is removed in the flushing of the water of phosphorus piece stone;

4.2 it is 120 order mineral fines that phosphorus piece stone is pulverized;

Mud is removed in the shale flushing 4.3 boil, also pulverizing is 80 purpose breezes;

Add other fertilizer and element 4.4 mix: major ingredient is: phosphorus piece stone ore powder is 65 percent; Zeolite powder 1 15; Fused(calcium magnesium)phosphate 10; Plant ash or biological waste 7 percent; Other element 3 percent;

4.5 it is dry by 50 kilogram of one packing bag (interior plastic film (leakproof), the two-layer packing of overcoat woven bag)

4.6 equipment, investment in fixed assets be the investment of equal megaton phosphate fertilizer plant less than 1/4th.

5, economic benefit and social benefit

5.1 survey institute's pertinent data according to the Guangdong woods, the Guangdong overseas Chinese takes back some teak seedlings in the sixties and plants in the various places, Guangdong about 1.2 cubic metres of the teak average product material at nearly 40 ages of strain more than 30 of existing investigation from Malaysia, Indonesia; And 36 ages of teak on limestone soil (alkalescence) are planted in Dehong state, Yunnan, and the average product material reaches 2.6 cubic metres, and difference is more than one times, and the main Guangdong of its reason is acid soil.And the author is from having proved the factuality (seeing accompanying drawing) of this greatest differences among the contrast experiments in Guizhou.And, invented this adjustment fertilizer through experiment contrast repeatedly, and using the result, teak surpasses the Yunnan Dehong in Guizhou early growth speed.From economic benefit, every kilogram of fused(calcium magnesium)phosphate can increase by 1.5 kilograms of grains, wound net income less than one yuan; And a strain teak is improved the soil of its pH value 7.5, only need the special-purpose fertilizer of adjusting of 6-10 kilogram (per kilogram is less than 0.5 yuan) just much of that, and different soil property teak is become a useful person price differential above ten thousand yuan.This fertilizer is called 4 two by the site inspection expert and dials thousand an ancient unit of weight, and " tree is precious " of making big profits with a small capital is the special-purpose fertilizer of adjusting of a kind of low-cost high-efficiency benefit of modern science forest culture and management " setting when the grain kind ".

5.2 annual nearly 80,000,000 cubic metres of China's timber breach, existing standing tree alive 80 percent is pine, China fir, poplar low value woods, and teak value is more than 60-200 times of this class timber value, other technological innovation of this adjustment fertilizer and inventor, created condition for China's south wide geographic area plantation rare tree teak, its potential benefit is beyond measure.

5.3 should invention belong to the discarded low value utilization of resources; Less energy-consumption (not roast), do not make Green Product, the project of artificial acidolysis, unharmful substance discharging (the polishing dust is only arranged).
