Problems solved by technology

A reasonable combination of the three will be an ideal fertilizer variety. However, because the living bacteria in microbial fertilizers are affected by salinity, temperature, etc., the combination of the three often results in unfavorable microbial survival. In an organic environment, the effect on the activity of microbial fertilizers is very important for the production of bio-organic-inorganic mixed fertilizers
The disadvantages of using the above-mentioned binder are: (1) the more the useless components are added, the lower the effective components of the fertilizer, so high-concentration compound fertilizers cannot be produced
For example, the three-component compound fertilizer of nitrogen, phosphorus and potassium (15-15-15) is granulated with clay binder, and the return rate is high, generally 30% to 50%, which increases energy consumption and costs
(2) Due to the distribution of resources, even if it is clay, there may not necessarily be resources near the production plant. Therefore, the transportation volume of railways and roads increases, and the production cost also increases.
[0005] So far, there is no special organic-inorganic compound fertilizer for sweet sorghum suitable for saline-alkali land

Embodiment 1

[0053] A special sweet sorghum compound fertilizer suitable for use in saline-alkali land, which is made of urea, monoammonium phosphate, Streptomyces flavinus culture, compound bacteria culture and amide polymer compound binder, each of which accounts for the weight percentage range yes:

[0054] Urea 6.65%;

[0055] Monoammonium phosphate 28%;

[0056] Streptomyces flavinus culture 10%;

[0057] Composite bacterial culture 55%;

[0058] Amide polymer compound binder 0.35%.

[0059]The composite bacteria is the composite bacteria that has been disclosed in the Chinese patent application with the application number of 200610083429.7 and is suitable for fermenting the kitchen organic waste. The product of expanded culture, wherein the Streptomyces flavinus in the culture of Streptomyces flavinus ≥ 7 billion / g; the organic matter in the culture of complex bacteria ≥ 46%.

[0060] The preparation method is:

[0061] 1) Raw material crushing: crush urea and monoammonium phos...

Embodiment 2

[0071] Production method is with embodiment 1, and raw material formula is as follows:

[0072] Urea 10.65%;

[0073] Monoammonium phosphate 23%;

[0074] Streptomyces flavinus culture 6%;

[0075] Composite bacterial culture 60%;

[0076] Amide polymer compound binder 0.35%.

[0077] The fertilizer test of sweet sorghum on saline-alkali land was carried out in Haixing County, Hebei Province. The test site is a moderately saline-alkali land with a test area of ​​10 mu. The sweet sorghum variety used in the test is "Italia". 25 kg of this sweet sorghum special fertilizer was used as base fertilizer in the test group, 40 kg of urea was used in the control group, and other fertilizer and water management was the same. Determination of sweet sorghum plant height, stalk sugar content (Brix), grain yield and biomass in the late growth period.

[0078] The test results showed that the sugar content (brix) in the stems of the test group was 17.42, and the sugar content (brix) in...

Embodiment 3

[0080] Production method is with embodiment 1, and raw material formula is as follows:

[0081] Urea 7.65%;

[0082] Monoammonium phosphate 30%;

[0083] Streptomyces flavinus culture 12%;

[0084] Composite bacterial culture 50%;

[0085] Amide polymer compound binder 0.35%.

[0086] The fertilizer test of sweet sorghum on saline-alkali land was carried out in Haixing County, Hebei Province. The test site is a moderately saline-alkali land with a test area of ​​10 mu.

Abstract

The invention discloses a compound fertilizer special for sweet sorghum and suitable for saline-alkali land, which is characterized in that: the compound fertilizer is prepared by urea, monoammonium phosphate, streptomyces microflavus culture, complex bacteria culture and an amide polymer compound binding agent. The fertilizer can provide the sweet sorghum with various nutrient substances which are in certain proportion and are suitable for the growth of the sweet sorghum on barren saline-alkali land, simultaneously, contains active microorganism which is more than or equal to 6*107 CFU / g, can improve a soil microflora, promotes nitrogen fixation, phosphorus releasing and potassium releasing effects of soil, enhances stress resistance and disease resistance of the sweet sorghum on the saline-alkali land, promotes the growth of the sweet sorghum and the accumulation of sugar, and improves the quality of the sweet sorghum.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a special bio-organic fertilizer for sweet sorghum suitable for saline-alkali land and a preparation method thereof. Background technique [0002] Sorghum is the most salt-tolerant crop among grain crops such as wheat and corn, and it is also the most suitable crop for the development of saline-alkali land. The poor salt tolerance of sweet sorghum is mainly manifested in the germination and seedling stage. First, the seeds are damaged by the salinity of the surface soil after sowing, and the seedlings cannot germinate, resulting in rotten buds; Seedling. But as long as the seedlings are kept, as the plants grow, the root system will gradually develop, and the salt tolerance of the plants will increase. In addition, the middle and late stages of growth are in the rainy season, the soil salt content will decrease, and the salt damage will be alleviated. Overcoming ...
