Embodiment 1

[0020] Example 1 The experiment was carried out in Zhaobao Town, Wen County, Henan Province in 2007-2008, with random block design, 3 repetitions, and the area of ​​the plot was 3 m×7 m. Wheat variety Rumai 0319 was selected as the test material. The soil texture of the test field is medium loam, and the organic matter content of the 0-20 cm plow layer is 10.8 g kg -1 , total nitrogen 1.4 g·kg -1 , Alkaline hydrolyzed nitrogen 98.7 mg·kg -1 , available phosphorus 58.2 mg·kg -1 , available potassium 86.5 mg·kg -1 , pH 7.5. The biogas slurry is taken from the biogas digesters normally used by farmers. The raw materials are mainly pig manure and urine. After fermentation for more than 3 months, it is fine, uniform, transparent and has no obvious fecal odor. The total nitrogen content in the biogas slurry is 0.14%. The total amount of nitrogen applied during the wheat growth period is 16 kg / 667m of pure nitrogen 2 10 days before sowing, the base application of biogas fertil...

Embodiment 2

[0041] Example 2 The experiment was carried out in Zhaobao Town, Wen County, Henan Province from 2008 to 2009, with a randomized block design, 3 repetitions, and a plot area of ​​3 m×7 m. Wheat variety Wenmai 28 was selected as the test material. The soil texture of the test field is medium loam, and the organic matter content of the 0-20 cm plow layer is 12.5 g kg -1 , total nitrogen 1.5 g·kg -1 , Alkaline hydrolyzed nitrogen 111.2 mg·kg -1 , available phosphorus 64.3 mg·kg -1 , available potassium 73.6 mg·kg -1 , pH 7.5. The biogas slurry is taken from the biogas digesters normally used by farmers. The raw materials are mainly human and livestock excrement and urine. After fermentation for more than 3 months, it is fine and uniform, transparent and has no obvious fecal odor. The total nitrogen content in the biogas slurry is 0.12%; The amount of nitrogen is pure nitrogen 18 kg / 667m 2 10 days before sowing, the base application of biogas fertilizer combined with botto...

Embodiment 3

[0061] Example 3 The experiment was carried out in Qugou Town, Anyang County, Henan Province from 2009 to 2010. The randomized block design was repeated 3 times, and the area of ​​the plot was 4.4 m×5 m. Wheat variety Zhengmai 366 was selected as the test material. The organic matter content of the 0-20 cm plow layer in the test field is 15.2 g·kg -1 , total nitrogen 1.7 g·kg -1 , Alkaline hydrolyzed nitrogen 122.7 mg·kg -1 , available phosphorus 52.1 mg·kg -1 , available potassium 104.6 mg·kg -1 , pH 7.5. The biogas slurry is taken from the biogas digesters normally used by farmers. The raw materials are mainly pig manure and urine. After fermentation for more than 3 months, it is fine, uniform, transparent and has no obvious fecal odor. The total nitrogen content in the biogas slurry is 0.20%. The total amount of nitrogen applied during the wheat growth period is 15 kg / 667m of pure nitrogen 2 10 days before sowing, the base application of biogas fertilizer combined ...

Abstract

The invention relates to a method for cultivating high-yield and high-quality winter wheat by use of biogas liquid. The method mainly comprises the following steps: soaking seeds with biogas liquid at 16-20 DEG C for 8-12 hours before seeding; applying 11-20 kg of urea per 667 m<2> in combination with intensive farming land preparation or irrigation of soil moisture; at the later period of wheat jointing, applying 3,000-6,000 kg of biogas liquid per 667 m<2> in combination with irrigation of soil moisture, wherein the nitrogen dosage for topdressing is 50-75% of the conventional dosage of nitrogenous fertilizer; and spraying biogas liquid at the middle-and-later period of wheat, wherein 35-45 kg of biogas liquid diluted by 0.5-1 times is sprayed per 667 m<2> at the booting period, 35-45 kg of stock biogas liquid is sprayed per 667 m<2> at the pustulation period, and a proper amount of kerosene, washing powder and monopotassium phosphate is dissolved and sprayed 1-2 times in the pustulation period. The biogas liquid using method is convenient and practical, has low cost, reduces the pollution of nitrogenous fertilizer and serious adverse impact of pesticide residue in the production of high-quality wheat, improves the seed quality, and realizes cultivation of high-quality wheat, resource utilization of agricultural waste and sustainable development of agriculture.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for cultivating high-yield and high-quality winter wheat by utilizing biogas slurry. Background technique [0002] Wheat is one of the main crops in northern my country, its sown area and output both account for more than 50% of grain crops, and it is the staple food of residents in northern my country. In recent years, with the improvement of people's living standards, the society's demand for high-quality special-purpose wheat has been increasing, and the planting area of ​​high-quality wheat has increased rapidly, but only about 1 / 3 of the wheat has reached the national first-level and second-level high-quality standards. With the upgrading of special flour products of processing enterprises and the continuous modernization of processing technology, the modern milling industry has put forward higher and higher requirements for the quality and stability of lar...
