Embodiment 1

[0019] Applying the Bacillus cereus with the deposit number CGMCC NO.0137 in stages to increase the SOD content in wheat seeds:

[0020] Before sowing in winter, apply nitrogen, phosphorus, and potassium base fertilizers to the soil. The base fertilizer per mu contains about 15kg of pure nitrogen and phosphorus (P 2 o 5 ) about 5kg, potassium (K 2 O) About 15kg;

[0021] Soak the wheat seeds in the aqueous solution of the bacillus (the concentration of the bacillus is 100-200 million CFU / mL) in advance for 1 day, and then sow the seeds after they are dry;

[0022] After the wheat enters the green stage, topdressing, add about 15kg of pure nitrogen and phosphorus (P 2 o 5 ) about 2.5kg;

[0023] After entering the wheat flag-picking period, spray bacterial fertilizer water until the wheat stems and leaves are fully moistened. The bacterial fertilizer water contains 0.1-0.2 billion CFU / mL of the bacillus, and also contains 1% urea, 1% ammonium sulfate, and 2% superphosphori...

Embodiment 2

[0027] Applying the Bacillus cereus with the deposit number CGMCC NO.0760 in stages to increase the SOD content in wheat seeds:

[0028] Before sowing in winter, apply nitrogen, phosphorus, and potassium base fertilizers to the soil. The base fertilizer per mu contains about 15kg of pure nitrogen and phosphorus (P 2 o 5 ) about 5kg, potassium (K 2 O) about 15kg;

[0029] Soak the wheat seeds in the aqueous solution of the bacillus (the concentration of the bacillus is 100-200 million CFU / mL) in advance for 1 day, and then sow the seeds after they are dry;

[0030] After the wheat enters the green stage, topdressing, add about 15kg of pure nitrogen and phosphorus (P 2 o 5 ) about 2.5kg;

[0031] After entering the wheat flag-picking period, spray bacterial fertilizer water until the wheat stems and leaves are fully moistened. The bacterial fertilizer water contains 0.1-0.2 billion CFU / mL of the bacillus, and also contains 1% urea, 1% ammonium sulfate, and 2% superphosphori...

Embodiment 3

[0035] Applying the Bacillus cereus with the deposit number CGMCC NO.0761 in stages to increase the SOD content in wheat seeds:

[0036] Before sowing in winter, apply nitrogen, phosphorus, and potassium base fertilizers to the soil. The base fertilizer per mu contains about 15kg of pure nitrogen and phosphorus (P 2 o 5 ) about 5kg, potassium (K 2 O) about 15kg;

[0037] Soak the wheat seeds in the aqueous solution of the bacillus (the concentration of the bacillus is 100-200 million CFU / mL) in advance for 1 day, and then sow the seeds after they are dry;

[0038] After the wheat enters the green stage, topdressing, add about 15kg of pure nitrogen and phosphorus (P 2 o 5 ) about 2.5kg;

[0039] After entering the wheat flag-picking period, spray bacterial fertilizer water until the wheat stems and leaves are fully moistened. The bacterial fertilizer water contains 0.1-0.2 billion CFU / mL of the bacillus, and also contains 1% urea, 1% ammonium sulfate, and 2% superphosphori...

Abstract

The invention provides a cultivation method for cereal crops rich in SOD. The cultivation method for the cereal crops rich in SOD comprises the step of applying bacillus cereus capable of producing the SOD to the cereal crops. Compared with a traditional cultivation method, by directly applying the bacillus cereus capable of producing the SOD to the cereal crops, it is wonderfully achieved that the content of the SOD of the cereal crops is improved by times, and the yield is significantly improved.

Description

technical field [0001] The invention relates to a planting method of SOD-rich cereal crops. Background technique [0002] At present, the cultivation of cereal crops in my country is still in a relatively backward and extensive mode. With the gradual upgrading of the consumption level of Chinese people, the consumption demand for green, pollution-free and functional cereal crops is growing rapidly. Superoxide dismutase (SOD) has a good scavenging effect on free radicals produced by body metabolism, so it has good practical value to further increase the SOD content in cereal crops on the basis of cultivating green, environmentally friendly and organic cereal crops . [0003] SOD-producing Bacillus cereus is an endophytic symbiotic bacterium, which has been studied by China Agricultural University and is mainly promoted in fruit trees, which can greatly increase the SOD production of the host, but the specific regulation of the bacteria on the host is not yet clear. [0004]...
