Description
Technical field
The present invention relates to a kind of microbial bacterial agents that wheat nutrient is promoted to absorb and preparation method thereof, belong to agricultural technology neck
Domain.
Background technology
Wheat (Triticum aestivum L.) is grass family wheat platymiscium, is most important cereal crops in the world
One of, it is the three big crops for being only second to rice and corn in China.Wheat is mostly extensive due to site preparation, sowing it is too shallow, root system compared with
It is weak, wheat seedling growth is made not strengthen, tillering node is in dry ground, and in the case of soil freezing, root is not hygroscopic, and overground part still has
Rising phenomenon makes wheat seeding be difficult to that internal water is maintained to balance, and be easy to cause arid death.Common Diseases have stripe rust of wheat, leaf
Rust, head blight etc..However head blight has become one of important disease for influencing yield and quality of wheat, causes decreased production,
Seriously affect Wheat Production safety and food security.It applies nitrogen and improves the generation that plant nitrogen concentration advantageously reduces head blight, increase
Add crop yield.
Microbial bacterial agent be microorganism by production expand it is numerous after, utilize viable bacteria made of the zymotic fluid of adsorbent absorption thalline
Preparation.This microbial inoculum has for seed dressing or root dipping and directly or indirectly improves soil, recover soil fertility, prevent soil-borne disease, maintain
The effects that rhizosphere microflora balance and degradation poisonous and harmful substances.The appropriate use of agricultural microbial agent can improve agricultural product
Yield improves quality of agricultural product, reduces fertilizer amount, reduce cost, improvement soil, preserve the ecological environment.
Agrobacterium rhizogenes (Agrobacterium rhizogenes) can induce the hairy root that plant generates, hairy root tool
There is the features such as growth cycle, condition of culture are simple, stability is strong, purpose product content is high.The plant that agrobacterium rhizogenes induction generates
Strain well developed root system, is conducive to the absorption of the minerals such as soil N P.Ri plasmids can induce conversion plant and generate a large amount of hair roots, promote
Into plant establishment, flourishing root system is conducive to improve plant resistance to environment stress, improves crop survival rate.So it is prepared using agrobacterium rhizogenes
Microbial inoculum is conducive to improve the nutrient absorption efficiency of wheat, further improves crop quality.
The content of the invention

The chitosan is that the active principle content produced on the market by hundred taste bio tech ltd of Hebei is
99.8% chitosan.
The agrobacterium rhizogenes bacterium solution is the Agrobacterium bacterium solution that OD values are 0.4-0.6.
The dodecyl sodium sulfate added in microbial inoculum is surfactant, can promote absorption of the plant root to microbial inoculum.
A kind of preparation process for the microbial bacterial agent that wheat nutrient is promoted to absorb is:
By agrobacterium rhizogenes strain A4, R1205, R1000, R1601, R1022, one or more of 15834 activation extremely
OD values are 0.4-0.6, must take the bacterium solution after activation, and the bacterium solution 100ml after activation is separately added into dodecyl sodium sulfate 2g, urine
Plain 40g, alginic acid 16g, chitosan 20g, mixing obtain microbial bacterial agent.
The present invention has following positive effect:
1st, the microorganism fungus kind that microbial bacterial agent of the present invention uses for agrobacterium rhizogenes strain A4, R1205, R1000,
R1601, R1022, one or more of 15834, agrobacterium rhizogenes can generate symbiosis with crop root, make its adventitious root
Growth is rapid, and induction plant generates hairy root, promotes the growth of wheat root, and by consolidating root system of plant, improving increases nutrient
Absorbability has achieved the effect that improve crop quality.
2nd, microbial bacterial agent of the present invention use agrobacterium rhizogenes bacterium solution, the components such as urea, dodecyl sodium sulfate, have into
The advantages of this is relatively low, easily obtains, and preparation method is simple, is readily put into production.
3rd, the preparation method of a kind of microbial bacterial agent that wheat nutrient is promoted to absorb using the present invention, solves wheat and exists
In growth course due to root system it is undeveloped caused by nutrient content is low and the problem of low output, there is huge economic benefit.
