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 ferti

Example Embodiment

[0052] Example 1:

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

[0054] Urea 6.65%;

[0055] Monoammonium phosphate 28%;

[0056] 10% of culture of Streptomyces flavus;

[0057] Compound bacterial culture 55%;

[0058] 0.35% of amide polymer compound binder.

[0059] The compound bacteria is a compound bacteria suitable for fermentation treatment of organic food wastes disclosed in the Chinese patent application with application number 200610083429.7, and the Streptomyces gracilis culture and the compound bacteria culture are carried out by using strains. The product of the expansion culture, among which the Streptomyces tenuifotus culture in the Streptomyces flavus ≥ 7 billion / g; the organic matter in the composite bacteria culture ≥ 46%.

[0070] Example 2:

[0071] The production method is the same as in Example 1, and the raw material formula is as follows:

[0072] Urea 10.65%;

[0073] Monoammonium phosphate 23%;

[0074] 6% of culture of Streptomyces flavus;

[0075] 60% of compound bacterial culture;

[0076] 0.35% of amide polymer compound binder.

[0077] This product was tested in the fertilizer experiment of sweet sorghum on saline soil in Haixing County, Hebei Province. The test site is a moderately saline-alkali land, the test area is 10 mu, and the test sweet sorghum variety is "Itari". The test group was treated with 25 kg of this sweet sorghum special fertilizer, and the control group was treated with 40 kg of urea. The management of other fertilizers and water was the same. The plant height of sweet sorghum, the sugar content of the stalk (the hammer degree), the grain yield and the biological yield were measured in the late growth stage.

[0078] The test results showed that the sugar content of the stems...

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 ...
