Abstract
The invention relates to special fertilizer resistant to continuous cropping of corn for seed. The special fertilizer resistant to continuous cropping of corn for seed is formed by uniformly mixing urea, monoammonium phosphate, zinc sulphate and a continuous cropping resistant agent according to the ratio of (55.20-63kg):(31.28-39kg):(3.31-4.99kg):(2.20-3.82kg) and then packaging. According to the special fertilizer resistant to continuous cropping of corn for seed, trophic action of urea, monoammonium phosphate and zinc sulphate and continuous cropping resistance of the continuous cropping resistant agent are integrated into a whole, the problem that soil-borne diseases of corn for seed in Hexi Corridor, Gansu are serious is effectively solved, and the yield of the corn for seed is increased and the quality of the corn for seed is improved.
Description
Technical field
The present invention relates to the Maize Production field, relate in particular to the special-purpose fertilizer of the anti-continuous cropping of a kind of production of hybrid seeds corn.
Background technology
Landlocked irrigated area, the west of a river, Gansu water resources is abundant, and light application time is long, and day and night temperature is big, and is dry, and natural isolation condition is good, is the desirable place of the corn seed production of hybrid seeds and storage, in recent years, has set up production of hybrid seeds Maize Production base 100,000 hm
2, seed yield reaches 6.5 Yi ㎏.The problem that highlights day by day at present is: production of hybrid seeds maize sown area is big, and the continuous cropping time limit reaches the plot in 10 ~ 15 years and accounts for more than 95%, because continuous cropping year limit for length, the soil microorganisms flora is unbalance, and soil-borne disease is serious, corn essential in, micro-proportional imbalance.Therefore, research and development collection nutrition, anti-continuous cropping are the key point that the special-purpose fertilizer of one becomes composite fertilizer's research and development.In recent years, the research of relevant composite fertilizer has been subjected to extensive concern, but yet there are no report about the special-purpose fertilizer of the anti-continuous cropping of production of hybrid seeds corn.
Summary of the invention
The anti-continuous cropping of production of hybrid seeds corn that technical problem to be solved by this invention provides a kind of effective raising production of hybrid seeds corn yield and quality is special-purpose fertile.
For addressing the above problem, the anti-continuous cropping of a kind of production of hybrid seeds corn of the present invention is special-purpose fertile, it is characterized in that: this special use fertilizer is formed by the even back of the mixed packing of 55.20kg ~ 63 kg:31.28 kg ~ 39 kg:3.31 kg ~ 4.99kg:2.20 kg ~ 3.82 kg by urea, monoammonium phosphate, zinc sulfate, successive planting resistant agent.
The particle diameter of described urea is 2 ~ 3mm, and to contain the N massfraction be 46%.
The particle diameter of described monoammonium phosphate is 2 ~ 5mm, and to contain the N massfraction be 12%, contain P
2O
5Massfraction is 52%.
The particle diameter of described zinc sulfate is 0.50 ~ 1mm, and to contain the Zn massfraction be 23%.
The particle diameter of described successive planting resistant agent is 0.50 ~ 1mm, and contains effective viable count 〉=2,500,000,000/g.
The present invention compared with prior art has the following advantages:
1, the present invention is raw material with urea, monoammonium phosphate, zinc sulfate, successive planting resistant agent, the anti-continuous cropping of synthetic a kind of production of hybrid seeds corn is special-purpose fertile, wherein successive planting resistant agent contains a large amount of probioticss, and the back breeding rapidly that is manured into soil can effectively be regulated because the soil micro-ecosystem that long-term continuous cropping causes is unbalance; The profitable strain that successive planting resistant agent contains survival and reproduction in soil can effectively decompose crop residues and residue and decompose and organic acid, aldehyde, alcohol, the hydro carbons plant-growth inhibition of generation; Simultaneously successive planting resistant agent contains the conversion that phosphorus decomposing, potassium decomposing, vinelandii group energy effectively promote soil material, improve the soil and fertilizer utilization ratio, replenish the nutrient of soil disappearance, it is big to have solved Hexi Corridor, Gansu Province production of hybrid seeds maize sown area effectively, continuous cropping year limit for length, the soil microorganisms flora is unbalance, corn essential in, problem such as micro-proportional imbalance.
2, the present invention is with the trophism of urea, monoammonium phosphate, zinc sulfate, and the anti-continuous cropping effect of successive planting resistant agent combines together, has solved the serious generation of Hexi Corridor, Gansu Province production of hybrid seeds Maize Soil Borne Disease effectively, has improved production of hybrid seeds maize yield and quality.
3, the present invention is carried out after the mass analysis as can be seen, product of the present invention reaches special-purpose fertile specification of quality (referring to table 1).
