High-efficiency formulated fertilizer for wheat planted in low-yield Shajiang black soil in Huaibei Plain

Abstract

The invention discloses a high-efficiency formulated fertilizer for wheat planted in low-yield Shajiang black soil in the Huaibei Plain. The formulated fertilizer comprises the following effective chemical elements by weight: in terms of pure nutrients, 12.0 to 22.0% of nitrogen, 6.0 to 12.0% of phosphorus, 5.0 to 15.0% of potassium, 2.0 to 6.0% of sulfur, 0.2 to 1.0% of zinc, 0.5 to 3.0% of manganese and 5.0 to 20.0% of a fertilizer nutrient synergist. The high-efficiency formulated fertilizer for wheat planted in low-yield Shajiang black soil in the Huaibei Plain has comprehensive nutrients and is reasonable in the proportioning of the nutrients; the high-efficiency formulated fertilizer accords with the fertility characteristics of low-yield Shajiang black soil in the Huaibei Plain and with the nutrient absorption rules of wheat, has high utilization rate and can obviously increase the contents of effective nitrogen, phosphorus and potassium nutrients of Shajiang black soil; and the high-efficiency formulated fertilizer can improve soil fertility, promote wheat growth, improve grain output and protein content, reduce fertilization cost, increase the economic benefits of fertilization, enhance the utilization efficiency of the fertilizer and reduce harmful influence on environment caused by unreasonable fertilization.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers and their applications, in particular to a high-efficiency formula fertilizer for wheat suitable for low-yield sand ginger black soil in the Huaibei Plain. Background technique [0002] Wheat is the main food crop in my country. The annual sown area of ​​the country is as high as 350 million mu, accounting for about 21% of the sown area of ​​food crops in my country, with a total output of 120 million tons, accounting for 34% of the total output of food crops in my country, second only to rice. No. 2. Anhui is one of the five major winter wheat producing provinces in my country. The province’s annual sown area is more than 30 million mu, of which the planted area in 2014 was as high as 36.45 million mu, with a total output of 13.93 million tons. The sown area and total output accounted for 10.1% of the country’s total respectively. % and 11.0%, second only to provinces such as Hena...

Problems solved by technology

[0006] The currently invented wheat formula fertilizers not only have few types, but are mainly used as base fertilizers, without consideration of later topdressing and the impact on wheat quality, and there is no specific formula for low-yield sand ginger black soil nutrient status

Announced a kind of wheat formula fertilizer as Chinese patent CN104355888A, coating (urea) fertilizer 40-60%, Yihua monoammonium 20-30%, Yunnan granular phosphate fertilizer 10-20%, Canadian potash fertilizer 5-10%, as seen this formula The proportion of potassium is low, and at the same time, it lacks trace elements, which cannot meet the needs of wheat growth and development for potassium and trace elements

Chinese patent CN104496610A discloses a wheat formula fertilizer for tidal mud fields, which contains 20 parts of nitrogen, 16 parts of phosphorus pentoxide, and 7 parts of potassium oxide.

Wheat formula fertilizer announced by Chinese patent CN106220328A, 80-100 parts of nitrogen, phosphorus and potassium compound fertilizer, 4-8 parts of medium and trace elements, 0.05-0.1 part of rare earth element, 60-100 parts of organic fertilizer, 10-15 parts of fluorspar powder, vermiculite 12-20 parts, although it contains trace elements, the ratio of nitrogen, phosphorus, potassium and trace element nutrients is not suitable for the northern soil, especially the low-yield sand ginger black soil in the Huaibei Plain, and the finished compound fertilizer is used as raw material
