Description
Technical field
The present invention relates to fertilizer fields more particularly to a kind of calcium and magnesium bio-organic fertilizer and preparation method thereof.
Background technique
In recent years, unreasonable due to chemical fertilizer application, lead to soil acidification, soil organic matter content decline, soil is beneficial
Microbial population, quantity decline, plant growth is other than N P and K and microelement, it is also necessary to a considerable amount of calcium, magnesium elements,
It due to continuously cultivating, after calcium magnesium element is taken away by crop, and is not supplemented, causes soil calcium magnesium element to lack, cause to make
Object nutritional imbalance, chemical fertilizer utilization ratio is low, and poor, growth retardation, yield drop in soil fertility and physicochemical property decline, stress resistance of plant
Quality decline.
Dolomite is carbonate mineral, and dolomite is heated to be decomposed into carbon dioxide and calcium oxide, oxidation at 700-900 DEG C
The mixture of magnesium, claims causticity magnesium marble, and Yi Yushui reacts.CaO content 30.4% in dolomite, content of MgO 21.7% are burnt
Vector is 44.5%-47.0%.
Total calcium is up to micro to 4% or more in soil, and full magnesium amount is generally 0.1%-4%, and majority is in 0.3%-2.5%
Between.Wet area of heavy rainfull, soil aciditiy is big, and calcium, magnesium solubility are high, and leaching loss is strong, and total calcium is lower than 1%；Arid and semi-arid
Area is generally 1% or more, often with the presence of free calcium carbonate.
The eluviation of calcium, magnesium in the soil is relatively slow compared with other base cations, is distributed in section relatively
It is even.Calcium, magnesium in soil are mainly inorganic states, organic calcium, magnesium proportion very little.Inorganic states calcium, magnesium have mineral state, replacement
State and water-soluble state.Mineral state calcium, magnesium proportion highest, mineral state calcium account for about the 40%-90% of full calcium, and mineral state magnesium accounts for about entirely
The 70%-90% of magnesium, this part calcium, magnesium are primarily present in primary and secondary mineral lattice.Calcium, magnesium often coexist in angle sudden strain of a muscle
Stone, pyroxene, in the mineral such as anorthite, dolomite, these host minerals are easily decomposed.Water-soluble and replacement property calcium, magnesium are that plant can
With quick-acting calcium, the magnesium being directly absorbed and utilized.Slightly solubility mineral state calcium, magnesium must can just be released through long-term weathering effect.
Moistening rainy south, shower is strong, and ease of solubility calcium, magnesium lack, can only lean on the weathering of slightly solubility mineral discharge a small amount of calcium,
Magnesium, it is difficult to meet crop needs, the case where calcium deficiency, magnesium deficiency easily occur, especially magnesium deficiency is even more serious.
Raw material of the dolomite in the neutralizer and breeding matrix for being agriculturally mainly used as acid soil, calcium magnesium element therein
It is difficult to be absorbed by crops utilization, causes the waste of resource.Currently, not having the calcium and magnesium using dolomite as raw material also on the market
Fertilizer.
Summary of the invention
The purpose of the present invention is to solve the shortcomings of the prior art and providing a kind of calcium and magnesium bio-organic fertilizer and its preparation
Method, crop are easy to absorb, and dolomite lime has the function of killing harmful microorganism in soil, avoid or reduce pest and disease damage
Generation, improve soil, adjust soil pH value, this technology dolomite lime mixes with organic fertilizer, functional form microbial bacterial agent

Cooperation enhancing.After Fertilizer in Rice calcium magnesium element fertilizer, blade angle reduces, and canopy photosynthetic organ improves 10% or more.
5, can enhance crop disease-resistant worm ability: after crop absorbs calcium, magnesium elements, cauline leaf cells of superficial layer wall thickeies, cuticula
Increase, to improve insect prevention disease resistance, especially blast resisting, leaf spot, stem rot, bacterial leaf-blight, bacterium column disease and cotton boll
Worm, rust etc..
6, crop can be improved and resist lodging ability: keeping the stalk of crop straight, lodging tolerance is made to improve 80% or so.
7, aeration in crop body can be made to enhance: calcium, magnesium elements amount increase in crop body, reinforce crop catheter,
Aeration is promoted to enhance, aquatic to rice, reed etc. and warm raw crop is significant, can also promote root growth, prevents
The rotten and early ageing of root system.Especially play an important role to rotten of prevention and treatment rice.
8, the resistance of crop can be improved: effectively adjusting the opening and closing of Stoma of Leaves, control moisture transpiration effect.It improves and makees
The imperial evil ability of drought resisting, hot-dry wind tolerance and low-temperature resistance.Calcium magnesium element fertilizer is suitable for rabi.Such as early rice, early peanut and winter
Spring vegetables production.
9, can reduce the fixation of phosphorus in the soil: anthropogenic soil apply after calcium magnesium element fertilizer can phosphorus in activating soil, promote
In the intracorporal operating of crop, to improve setting percentage.

2 results and analysis
2.1 breeding times progress
As seen from Table 1, compared with the control, T1, T2 processing enter group's phase and the time of prosperous growth phase all shifts to an earlier date 2 days, say
Bright application calcium and magnesium biological organic fertilizer and functional biological organic fertilizer are all conducive to the growth of root system, and cigarette strain is promoted to go back rapidly after transplanting
Seedling promotes cigarette strain early growth and quick tiller.And the cigarette strains of two processing group's phase, the prosperous growth phase, squaring period, the phase of binding, just the roasting phase and
The time for adopting roasting end all shifts to an earlier date 1-2 days compared with check plot, field reduction in the life period 2 days, illustrates calcium and magnesium biological organic fertilizer and function
Biological organic fertilizer can be shortened the flue-cured tobacco growing stage time, promote tobacco leaf hacking and in advance maturation.
1 breeding time of table progress
2.2 field growing way appearance
The growing way appearance investigation result of each processing flue-cured tobacco primary growth stage is shown in Table 2.T1, T2 and control as can be seen from the table
Growing way appearance it is almost the same, but T1, T2 processing cigarette strain maturity be significantly better than check plot, be conducive to cigarette strain normal mature and fall
It is yellow.
2 field growing way appearance of table
2.3 economical character
The survey showed that for economical character after binding, and economical character overall performance is T1 > T2 > control.Thus illustrate, apply
Calcium and magnesium biological organic fertilizer and functional biological organic fertilizer can promote the growth and development of flue-cured tobacco prosperous growth phase, and growing way is better than check plot.
Table 3 binds economical character after the phase
A situation arises for 2.4 diseases
Major Diseases around test are mosaic disease, balck shank, tomato spotted wilt and weather spot disease.It can be with from table 4
Find out, T2 and the disease incidence difference for compareing various diseases are little, but the disease incidence of T1 processing cigarette strain is significantly lower than at other two
Reason illustrates that the disease incidence of cigarette strain can be reduced by applying calcium and magnesium biological organic fertilizer.
