(1) technical field the present invention relates to a kind of agricultural composition, particularly the fertilizer in agricultural composition, agricultural chemicals.
(2) the background technology vegetables are human lives's product, and Various Diseases insect pest and the nutritional deficiency diseases such as damping-off, samping off, bacterial wilt, oidium and cabbage caterpillar, small cabbage moth noctuid easily occur for brassicaceous vegetable and rape seedling, often cause heavy losses to agriculture production.Existing solution is to carry out prevention and elimination of disease and pests by spraying chemical pesticide; Solve nutritional deficiency disease by fertilising.If but improper fertilization often can make quality of vegetable descend, also can produce inferior pin acid pollution environment and underground water; Chemical pesticide is used the improper pesticide-tainted vegetable events such as pesticide residue that also can cause.
(3) summary of the invention
1, goal of the invention the objective of the invention is the agronomy needs of growing seedlings according to brassicaceous vegetable and rape, combining of the microbial pesticide of several low toxicities and mineral manure science, provide a kind of rational nutrition in seedling stage can be provided, can prevent and treat again the multifunctional and nutritional composition of the low toxicity of seedling stage diseases and pests, for brassicaceous vegetable and rape nursery stage.
2, technical scheme technical scheme of the present invention is:
A kind of brassicaceous vegetable and rape are grown seedlings and are used multi-effect nutritive composition, and the weight percentage of its composition and each component is:
A trichoderma harziarum (Trichoderma harzianum Rifai) or Trichoderma (Trichodermaspp.) 6-15%;
B Paenibacillus polymyxa (Paenibacillus? polymyxa) 8-15%;
C Bacillus thuringiensis (Bacillus thuringiensis, B.t.) 10--18%;
N 8-15% in D nitrogenous fertilizer;
P in E phosphate fertilizer
2O
54-10%;
K in F potash fertilizer
2O 2-10%;
G weighting material surplus.
The existing people of trichoderma harziarum in said components (Trichoderma harzianum Rifai) applies for Chinese patent, and number of patent application is 200910079781; This bacterial strain has been preserved in China Committee for Culture Collection of Microorganisms's common micro-organisms center on January 21st, 2009; Preserving number is CGMCC No.2870.
Quality standard 200,000,000 spore/gram alive of Trichoderma (Trichodermaspp.).
Paenibacillus polymyxa (Paenibacillus? polymyxa) 0.1 hundred million/gram, the existing people of this bacterial strain is preserved in the Chinese Typical Representative culture collection center (CCTCC) that is positioned at Lopa Nationality an ancient woman's ornament mountain, Wuhan City Wuhan University, preservation date is on July 19th, 2009, is preserving number CCTCC? N O:M 209157.
Bacillus thuringiensis (Bacillus th uringiensis) is the fritz Bel a kind of bacterium that very strong insecticidal power is arranged how (Berliner) is separated to from the Mediterranean flour moth in a milling plant in this place of German Su Yun Jin Sheng, and formally name and be Tribactur (Bacillus thuringiensis, B.t.), occupied the agricultural materials market one-hundred-year history.Can be in depositary institution obtains bacterial strain or product the isolated strains culture medium culturing.Quality standard is 8000IU/ milligram or 2000IU/ microlitre.
The equal commercially available prod of above-mentioned bacterial classification, existing enterprise obtains agriculture chemical registration.As PD20096832, PD20096833, LS20040563, PD20092318, PD90106-21.
Three kinds of compositions of N/P/K can be with commercially available ammonium sulfate/ammonium chloride/urea/sulphur acid potassium/Repone K/phosphoric acid one money/preparations such as diammonium phosphate/double superhosphate.
Weighting agent can be with wilkinite or careless carbon or pure water.
3, beneficial effect the present invention is according to the agronomy needs of brassicaceous vegetable and rape nursery stage, combining of the microbial pesticide of several low toxicities and mineral manure science, provide a kind of rational nutrition in seedling stage can be provided, can prevent and treat again the multifunctional and nutritional composition of the low toxicity of disease/insect pest in seedling stage, for brassicaceous vegetable and rape nursery stage.Having reached to provide rational nutrition in seedling stage, the purpose that can prevent and treat again seedling stage diseases and pests.Through on probation, can reach goal of the invention fully.
(4) embodiment the present invention also can be described further in conjunction with example
The below is several example of the present invention, (consumption is weight percentage):
The invention is not restricted to these examples.
N in component can be with urea or ammonium sulfate; P
2O
5Phosphoric acid one ammonium or diammonium phosphate; K
2O can be with saltpetre or vitriolate of tartar; Weighting agent: the solid phase prod weighting agent can be with wilkinite or careless carbon; The liquid product weighting agent is pure water.
Said components is determined the formulation consumption after converting by proportioning and content, the formulation of each component is mixed namely get product.
In said components, N/P/K is all readily avaiable fertilizer, supplies with the necessary nutrient of Growth of Seedling; Trichoderma/Paenibacillus polymyxa/can prevent sprout term disease promotes growth of seedling; Bacillus thuringiensis can prevent and treat the insect pest in seedling stage.Whole composition has reached can provide rational nutrition in seedling stage, the purpose that can prevent and treat again seedling stage diseases and pests and low toxicity.
During use, product of the present invention can be sprinkled into required seedbed of growing seedlings with appropriate (general 1: 10) earth uniform mixing and use, or be watered the pouring seedbed at 1: 100 and use.
