[0015] Example 2
[0016] High-efficiency release-resistant biological fertilizer, the components are as follows: ethyl propionate 5kg, ribonucleic acid 15kg, ammonium molybdate 10kg, zinc sulfate 5kg, silicon oxide 15kg, boric acid 5kg, potassium dihydrogen phosphate 4kg, citric acid 5kg, copper sulfate 4kg, Manganese sulfate 2kg, magnesium sulfate 1kg, Bacillus amyloliquefaciens powder 10kg and sodium dodecylbenzenesulfonate 6kg.
[0017] The preparation method of high-efficiency release-resistant biological fertilizer comprises the following steps:
[0018] The 1st step, prepare raw materials by the following weight kg number: ethyl propionate 5kg, ribonucleic acid 15kg, ammonium molybdate 10kg, zinc sulfate 5kg, silicon oxide 15kg, boric acid 5kg, potassium dihydrogen phosphate 4kg, citric acid 5kg, sulfuric acid Copper 4kg, manganese sulfate 2kg, magnesium sulfate 1kg, Bacillus amyloliquefaciens powder 10kg and sodium dodecylbenzenesulfonate 6kg;
[0019] In the second step, 10kg of ammonium molybdate in the first step, 5kg of zinc sulfate, 15kg of silicon oxide, 5kg of boric acid, 4kg of potassium dihydrogen phosphate, 4kg of copper sulfate, 2kg of manganese sulfate, and 1kg of magnesium sulfate are mixed uniformly to obtain a premixed material ;
[0020] In the 3rd step, after mixing 5 kg of citric acid in the 1st step and 100 kg of water evenly, a citric acid solution is obtained, which is added to the premixed material obtained in the 2nd step, and poured into a mixer for mixing treatment to obtain mixed powder for later use;
[0021] In step 4, mix 5 kg of ethyl propionate and 15 kg of ribonucleic acid in step 1 evenly, stir with the mixed powder obtained in step 3, pour it into a fermenter, stir fully, and ferment for 30 days, take out Air-dried and crushed.
[0022] Control group 1
[0023] The difference with Example 1 is: no ethyl propionate 5kg was added.
[0024] High-efficiency release-resistant biological fertilizer, the components are as follows: ribonucleic acid 15kg, ammonium molybdate 10kg, zinc sulfate 5kg, silicon oxide 15kg, boric acid 5kg, potassium dihydrogen phosphate 4kg, citric acid 5kg, copper sulfate 4kg, manganese sulfate 2kg, magnesium sulfate 1kg.
[0025] The preparation method of the high-efficiency release-resistant biological fertilizer is the same as in Example 1.
[0026] Control group 2
[0027] The difference with Example 1 is: 15kg of ribonucleic acid is not added.
[0028] High-efficiency and release-resistant biological fertilizer, the components are as follows: ethyl propionate 5kg, ammonium molybdate 10kg, zinc sulfate 5kg, silicon oxide 15kg, boric acid 5kg, potassium dihydrogen phosphate 4kg, citric acid 5kg, copper sulfate 4kg, manganese sulfate 2kg, Magnesium sulfate 1kg.
[0029] The preparation method of the high-efficiency release-resistant biological fertilizer is the same as in Example 1.
[0030] Control group 3
[0031] The difference with embodiment 1 is: do not add ethyl propionate 5kg and ribonucleic acid 15kg.
[0032] High-efficiency and release-resistant biological fertilizer, the components are as follows: 10kg of ammonium molybdate, 5kg of zinc sulfate, 15kg of silicon oxide, 5kg of boric acid, 4kg of potassium dihydrogen phosphate, 5kg of citric acid, 4kg of copper sulfate, 2kg of manganese sulfate, and 1kg of magnesium sulfate.
[0033] The preparation method of the high-efficiency release-resistant biological fertilizer is the same as in Example 1.
[0034] Control group 4
[0035] The fertilizer whose patent number is 201010204235.4 is adopted.
[0036] In 2014, a field test was carried out in Yinzhou, Ningbo using the fertilizer produced by the present invention. The material used is rice, and the variety is Wuyou 103. The treatments set up in the test are the fertilizers of the control experimental group 1-4 and the examples 1-2 of the present invention. Select 6 paddy farmlands with an area of 1 mu as the experimental field, wherein 2 farmlands use the high-efficiency release-resistant biological fertilizer obtained in the embodiment of the present invention 1-2 respectively, and the other 4 farmlands use the fertilizer obtained from the control experiment group 1-4 After the flowering period, 60 kg of the above-mentioned fertilizers were applied to each mu of rice, and other field management conditions were the same. The experimental results of observing rice after harvesting in autumn are shown in the following table:
[0037]
[0038] The results in the table show that the high-efficiency anti-release bio-fertilizer provided by the embodiment of the present invention 1 has a higher improvement for the output of rice and the seed setting rate relative to the control experiment group 4, in the embodiment 2 by adding the bacillus amyloliquefaciens powder And sodium dodecylbenzene sulfonate can further increase yield and seed setting rate. Can find out by contrasting experimental group 1~3, contrasting experimental group 1 adds ribonucleic acid on the basis of contrasting experimental group 3, contrasting experimental group 2 adds ethyl propionate on the basis of contrasting experimental group 3, all can not obviously improve Seed setting rate and output, and in embodiment 1, added ribonucleic acid and ethyl propionate simultaneously, can obviously improve seed setting rate and output.
