Problems solved by technology

For example, CN101037369A discloses a kind of full-nutrition bio-type flushing fertilizer. This product is widely used in economic crops such as facility vegetables, melons and fruits, and tobacco. It is not applicable in the technology, and its nutrient distribution ratio is not suitable for field wheat crops; CN102050648A discloses a new type of solid flushing fertilization, which is also a large water flushing fertilizer, and its nitrogen, phosphorus and potassium macroelement ratio is not suitable for Wheat grows in spring, and it is not conducive to saving water resources
So far, there have been no reports of special fertilizers for wheat that can be applied to the "water and fertilizer integration" micro-sprinkler irrigation technology for winter wheat growth in winter and spring and its application methods. Many problems are unfavorable, and there are product bottlenecks in the popularization of winter wheat "water and fertilizer integration" technology

Embodiment 1

[0041] The invention discloses a special fertilizer A for the integration of water and fertilizer for winter wheat, which is mainly used for nutrient input for spray irrigation and fertilization of wheat from sowing to late jointing stage. Its proportioning raw material parts by weight are as follows:

[0042] 42 parts of urea, 28 parts of diammonium phosphate, 14 parts of potassium chloride, 10 parts of potassium humate, 1.5 parts of borax, 2 parts of zinc sulfate, 0.7 parts of copper sulfate, 0.8 parts of ferrous sulfate, 0.7 parts of manganese sulfate, 0.3 parts of amino acid .

[0043] The finished raw materials above are crushed, all passed through an 80-mesh sieve to form powdery solids, mixed evenly, and packed in bags to obtain the special fertilizer A for the integration of water and fertilizer for winter wheat. The special fertilizer for wheat is suitable for application in the form of spray fertigation after wheat sowing to jointing, and the application method is a...

Embodiment 2

[0048] A special fertilizer B1 for the integration of water and fertilizer for winter wheat, which is mainly used for the nutrient input of spray irrigation and fertilization of wheat from the booting stage to the middle stage of grain filling. Its proportioning raw material parts by weight are as follows:

[0049] 49 parts of urea, 20 parts of diammonium phosphate, 17 parts of potassium chloride, 8 parts of potassium humate, 1.8 parts of borax, 1.2 parts of zinc sulfate, 0.9 parts of copper sulfate, 0.6 parts of ferrous sulfate, 1 part of manganese sulfate, 0.5 parts of amino acid .

[0050] The above-mentioned finished raw materials are crushed and passed through a 80-mesh sieve to form a powdery solid, which is weighed in parts by weight, mixed evenly, and packed in bags to obtain the special fertilizer B1 for the integration of water and fertilizer for winter wheat.

[0051] The special fertilizer for wheat is suitable for application in the form of spray fertilization fr...

Embodiment 3

[0055] A special fertilizer B2 for the integration of water and fertilizer for winter wheat, its proportioning raw material weight parts are as follows:

[0056] 47 parts of urea, 22 parts of diammonium phosphate, 18 parts of potassium chloride, 7 parts of potassium humate, 2 parts of borax, 1.1 parts of zinc sulfate, 1 part of copper sulfate, 0.7 parts of ferrous sulfate, 0.8 parts of manganese sulfate, 0.4 parts of amino acid .

[0057] The above-mentioned finished raw materials are crushed and passed through an 80-mesh sieve to form a powdery solid, which is mixed evenly and packed in bags to obtain the special fertilizer B2 for the integration of water and fertilizer for wheat.

[0058] The special fertilizer for wheat is suitable for application in the form of spray fertilization from the late jointing stage to the mid-filling stage of wheat. The application method is as follows:

[0059] In the later stage of wheat jointing to the mid-stage of filling, apply 10-15kg of...

Abstract

The invention relates to a water and fertilizer integrated fertilizer special for winter wheat, and an application method for the water and fertilizer integrated fertilizer. The water and fertilizer integrated fertilizer is prepared by uniformly mixing the following raw materials in part by weight: 40 to 50 parts of urea, 20 to 32 parts of diammonium phosphate, 12 to 18 parts of potassium chloride, 6 to 12 parts of potassium humate, 1 to 2 parts of borax, 1 to 2 parts of zinc sulfate, 0.5 to 1 part of copper sulfate, 0.5 to 1 part of ferrous sulfate, 0.5 to 1 part of manganese sulfate and 0.3to 0.5 part of amino acid. Water and fertilizer are supplied to wheat in a spray irrigation mode, a small amount of fertilizer is applied for multiple times, the fertilizer application amount, the irrigation amount and a water and fertilizer requirement rule of the winter wheat are basically matched, the continuous nutrient requirement of the winter wheat in a long growth period can be met, the ear rate is improved, and the obvious production and income increasing effect can be achieved. By the invention, boundaries of furrows and ridges in a field can be broken, and the land utilization rate is improved by over 5 percent.

Description

technical field [0001] The invention relates to a special fertilizer integrating water and fertilizer for winter wheat and an application method thereof, belonging to the technical field of agricultural fertilizers. Background technique [0002] Wheat is one of the main food crops in my country, and it is planted all over the country. In my country, wheat mainly includes winter wheat and spring wheat, among which the planting area of ​​winter wheat accounts for more than 90% of the total planting area of ​​wheat, and its area and total output are in the main position. However, winter wheat has a long growth period, which takes 230-240 days from sowing to harvest. During such a long growth period, wheat growth is significantly affected by climate, soil, fertilizer, irrigation, pests and weeds, and water and fertilizer are The main factors affecting the stability or increase of winter wheat production in recent years, especially in the North China winter wheat area, which is t...
