Embodiment 1

[0018] The present invention proposes a special fertilizer for winter wheat to resist dry and hot wind, water and fertilizer, and its raw materials include 30 parts by weight of superphosphate, 42 parts of urea, 26 parts of potassium sulfate, 1.4 parts of boron fertilizer, and 1.2 parts of zinc sulfate heptahydrate. Parts, 15 parts of fly ash, 0.8 parts of coated polyglutamic acid, 18 parts of biochar, 7 parts of bentonite.

Embodiment 2

[0020] The present invention proposes a special fertilizer for winter wheat to resist dry and hot wind, water and fertilizer, and its raw materials include 36 parts by weight: superphosphate 36 parts, 36 parts urea, 32 parts potassium sulfate, 1 part boron fertilizer, and 1.6 zinc sulfate heptahydrate. Parts, 10 parts of fly ash, 1.2 parts of coated polyglutamic acid, 14 parts of biochar, 9 parts of bentonite.

[0021] The coated polyglutamic acid is prepared by the following process: soy lecithin, distearoylphosphatidylethanolamine-carboxypolyethylene glycol, and anhydrous ethanol are uniformly mixed to obtain pretreated soybean lecithin; polyglutamic acid and polylactic acid , Acetylene cyanide is mixed uniformly, and the pretreated soybean lecithin is added dropwise in an ice water bath for ultrasonic treatment to remove organic solvents and free molecules to obtain coated polyglutamic acid.

Embodiment 3

[0023] The present invention proposes a special fertilizer for winter wheat to resist dry and hot wind, water and fertilizer, and its raw materials include 32 parts by weight of superphosphate, 40 parts of urea, 28 parts of potassium sulfate, 1.3 parts of boron fertilizer, and 1.3 parts of zinc sulfate heptahydrate. Parts, 14 parts of fly ash, 0.9 parts of coated polyglutamic acid, 17 parts of biochar, 7.5 parts of bentonite.

[0024] The coated polyglutamic acid is prepared by the following process: 2 parts by weight of soybean lecithin, 4 parts of distearoylphosphatidylethanolamine-carboxypolyethylene glycol, and 15 parts of absolute ethanol are mixed uniformly to obtain pretreated soybean lecithin ; Mix 2 parts of polyglutamic acid, 20 parts of polylactic acid, and 25 parts of acetonitrile uniformly, add the pretreated soybean lecithin drop by drop into an ice water bath for ultrasonic treatment for 65 minutes, remove organic solvents and free molecules to obtain coated polyglu...

Abstract

The invention discloses dry hot air-resistant water-retention fertilizer-conservation special-purpose fertilizer for winter wheat. The dry hot air-resistant water-retention fertilizer-conservation special-purpose fertilizer comprises, by weight, 30-36 parts of calcium superphosphate, 36-42 parts of urea, 26-32 parts of potassium sulfate, 1-1.4 parts of boron fertilizer, 1.2-1.6 parts of zinc sulphate heptahydrate, 10-15 parts of fly ash, 0.8-1.2 parts of coated polyglutamic acid, 14-18 parts of biochar and 7-9 parts of bentonite. The dry hot air-resistant water-retention fertilizer-conservation special-purpose fertilizer has good effects, saves time and labor, improves wheat stress resistance and improves soil and a water retention capability of soil.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for winter wheat to resist dry and hot wind and retain water and fertilizer. Background technique [0002] Winter wheat is a crop with a wide planting area and relatively stable yield in my country, and its growth process will be threatened by many natural disasters. In the later stage of wheat growth, the dry and hot wind disaster is the most serious agrometeorological disaster affecting wheat filling, and it is one of the most important disasters affecting wheat production in the north. [0003] Dry hot air is also called "fire air", "hot air" and "dry air". The leading factor of dry-hot wind damage to wheat is heat, followed by dryness, and wind is the co-factor. There are many harmful factors to wheat by dry and hot wind, and the degree of damage is firstly related to the resistance of wheat. There are many methods to prevent wheat dry and hot wind, such ...
