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. 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.
[0087] The test results showed that the sugar content (brix) in the stalks of the test group was 17.25, the sugar content (brix) in th...
