Description
Technical field
The present invention relates to field of agricultural production technologies, more particularly to a kind of rice seedling-growth soil regulator.
Background technology
Rice originates in Tropical Asian, after China widely plants, gradually travels to all over the world, rice is tied the grain of rice and shelled
Claim rice or rice afterwards, in the world nearly half population, all using rice as food, compared with other crops, contained nutrition composition in rice
Can digestibility and absorptivity it is higher, be most suitable for the needs of human body.After northern China introduces rice, because northern breeding time is short,
Directly sow that rice yield is low, poor quality, so rice in north china, using two-part cultivation, first paragraph is the greenhouse seedling phase, works as seedling
Seedling passes through the growth of 35~40 days, when being three one heart stages of leaf, carries out Honda rice transplanting, is cultivated into second stage.Northern area water
Rice seedling is at the beginning of annual 4 months, and temperature on average is 0.1 degree, and raising rice seedlings are carried out in canopy is educated, due to air humidity in seedling culture shed
Greatly, excessive growth easily occurs for rice, and Root Growth of Rice is weak, and physiological disturbance and pathologic disease easily occur for rice shoot；Conventional rice
Strong seedling agent only serves nutrition, acid adjustment and disinfective action, insufficiency face, is unfavorable for rice seedling and grows.Feces of livestock and poultry contains
There is abundant nutriment, but cannot effectively utilize for a long time, be deposited in plant's ambient contamination environment, feces of livestock and poultry is harmless
After change processing, by allotment, rice seedling-growth soil regulator component can be used as, Seedling Quality in Rice can be improved, rice seedling-slowing stage is short after rice transplanting；
The present invention is the agriculture waste utilization of resources, mitigates the destruction to environment, maintains agricultural sustainable development, all significant.
The content of the invention
The defects of present invention is directed to prior art, there is provided a kind of rice seedling-growth soil regulator, can effectively solve the problem that above-mentioned existing skill
The problem of art is present.
In order to realize above goal of the invention, the technical scheme that the present invention takes is as follows：
A kind of rice seedling-growth soil regulator, it is made up of following raw material：
Pulvis 50-60% of the feces of livestock and poultry after harmless treatment；

Preferably, the preparation method of pulvis of the feces of livestock and poultry after harmless treatment is as follows：Feces of livestock and poultry heap
Product fermentation, material temperature are kept for 65~70 DEG C ferment 5~7 days, after fermentation 38-42 days, when 33-37 DEG C of material temperature, are stopped fermentation, are entered sector-style
Pulvis obtained by dry grinding, water content >=30%.
Preferably, sulfuric acid >=98% in the concentrated sulfuric acid.
Preferably, N mass fraction is 46% in the urea.
Preferably, P2O5 mass fraction is 18% in the calcium superphosphate.
Preferably, K2O mass fraction is 50% in the potassium sulfate.
Preferably, Zn mass fraction is 20% in the zinc sulfate.
Preferably, naa >=98% in the naa.
Preferably, paclobutrazol >=15% in the paclobutrazol.
Present invention also offers the application method based on above-mentioned rice seedling-growth soil regulator, comprise the following steps：It is strong by 1.25 kilograms
Seedling agent fully mixes with 100 kilograms of native powder of sieving, is fitted into 75 seedling-cultivation plates (10 square metres), is sowed in the above with seeder
Or broadcast sowing rice paddy seed.
Compared with prior art the advantage of the invention is that：
Compared with conventional rice strengthens seedling agent, there is collection wasted resources, nutrition, acid adjustment, sterilize, take root, changing control function
In integral the characteristics of, the gas permeability of soil can be improved, improve rice shoot tillering capacity, make that rice shoot root long, root are more, root is heavy, stem is thick, cauline leaf
It is tall and straight, strong stress resistance, turned green after rice transplanting fast, kipeming high yield, and this product is pollution-free to soil environment, is that green rice produces
The preferred means of production.
Embodiment
For the objects, technical solutions and advantages of the present invention are more clearly understood, by the following examples, the present invention is done into
One step describes in detail.
