Embodiment 1

[0008] The special fertilizer for rice containing biogas residue is composed of 38 parts by weight of urea, 17 parts of diammonium phosphate, 3 parts of potassium sulfate, 42 parts of biogas residue, and the water content in the biogas residue is 5%.

Embodiment 2

[0010] The special fertilizer for rice containing biogas residue is composed of 42 parts by weight of urea, 19 parts of diammonium phosphate, 6 parts of potassium sulfate, 38 parts of biogas residue, and the water content in the biogas residue is 3%.

[0011] The present invention is a special fertilizer for rice based on biogas residue, which is proved to be especially suitable for the application in fields with medium and high fertility level of rice in the irrigation area diverted from the Yellow River in Ningxia, that is, paddy fields with a yield of 600-700kg per mu, N:P 2 o 5 : K 2 O=20:8:2, active ingredient ≥30. Fertilization method: before transplanting (or before sowing) when preparing the soil (rotate the field or harrow the field after spreading), or use a fertilizer machine to sow the soil, the amount of fertilization per mu is 100kg, and then topdressing urea 10kg at the jointing stage of rice. Can.

Abstract

The invention relates to a special paddy fertilizer containing biogas residue. The fertilizer is characterized by comprising the following components in part by weight: 32 to 42 parts of urea, 15 to 19 parts of diammonium phosphate, 2 to 6 parts of potassium sulfate, and 38 to 45 parts of biogas residue. The special paddy fertilizer develops a new path based on harmless treatment of the biogas residue, changes the current situation that single inorganic fertilizers are applied in paddy production, can reduce secondary pollution of the biogas residue, improves the yield and the quality of crops to a certain degree, and shows good fertilizer effects.

Description

technical field [0001] The invention relates to a special fertilizer for rice containing biogas residue. Background technique [0002] Biogas residue is the semi-solid material left after biogas fermentation, which is rich in organic matter, humic acid, amino acid, nitrogen, phosphorus, potassium and trace elements. At present, its main uses are as soil improver, crop base fertilizer and top dressing, preparation of nutrient soil for flower and vegetable seedlings, cultivation of edible fungi, cultivation of earthworms and eels, etc., but its utilization scale is generally small, and there is no large-scale direct use of biogas residue. better way. Contents of the invention [0003] The purpose of the present invention is to provide a special fertilizer for rice containing biogas residues, thereby providing a new way out for the utilization of biogas residues, and the cost of fertilizers is low, and the rice yield of applying this special fertilizer is not lower than that...
