Embodiment 1

[0026] A high-efficiency water-retaining blended fertilizer is characterized in that the components of the raw materials are composed as follows according to weight percentage:

[0027] 15% urea, 8% diammonium phosphate, 12% potassium sulfate, 0.1% borax, 0.05% zinc sulfate, 10% polyacrylamide, 37% clay.

Embodiment 2

[0029] A high-efficiency water-retaining blended fertilizer is characterized in that the components of the raw materials are composed as follows according to weight percentage:

[0030] 18% urea, 9% diammonium phosphate, 16% potassium sulfate, 0.15% borax, 0.08% zinc sulfate, 13% polyacrylamide, 45% clay.

[0031] The high-efficiency water-retaining blended fertilizer was prepared according to the raw materials in Example 2, and it was compared with the common blended fertilizer in a field test, and the test site was in the experimental field of Qingdao Agricultural University.

[0032] Table 1 Wheat chlorophyll content (SPAD value) under different treatments

[0033]

[0034] It can be seen from Table 1 that the chlorophyll of wheat treated with high-efficiency water-retaining blended fertilizers is greater than that of ordinary water-retaining fertilizers, which shows that the application of high-efficiency blended fertilizers can well increase the chlorophyll cont...

Embodiment 3

[0039] A high-efficiency water-retaining blended fertilizer is characterized in that the components of the raw materials are composed as follows according to weight percentage:

[0040] 20% urea, 10% diammonium phosphate, 18% potassium sulfate, 0.2% borax, 0.1% zinc sulfate, 15% polyacrylamide, 55% clay.

Abstract

The invention discloses a high-efficiency water-retaining blended fertilizer and a production method thereof. The raw materials of the fertilizer are as the following, by weight: 15-20% of urea, 8-10% of diammonium phosphate, 12-18% of potassium sulfate, 0.1-0.2% of borax, 0.05-0.1% of zinc sulfate, 10-15% of polyacrylamide, and 37-55% of clay. With the raw materials, a multifunctional novel fertilizer with a water-retaining function, fertilizer effect and a soil-improving function is formed. The high-efficiency water-retaining blended fertilizer is safe and environment-friendly, and is nontoxic and odorless. The fertilizer does not pollute plants, soil, groundwater and the like. The fertilizer leaves no residue organic or inorganic harmful substance. The blended fertilizer is suitable for mechanical fertilization, and can be applied to various crops and soils. The blended fertilizer can repeatedly absorb and store fertilizer and water, and can slowly release the fertilizer and water during drought. With the blended fertilizer, crop drought resistance can be enhanced, and nutrient balance can be coordinated. Fertilizer and water utilization rate can be improved, and crop yield can be significantly improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a high-efficiency water-retaining mixed fertilizer and a production method thereof. Background technique [0002] my country's total water resources ranks sixth in the world, but its per capita water resources are 1 / 4 of the world's average level, ranking 121st in the world, and it is one of the 13 water-poor countries in the world. Moreover, my country's central and western regions are seriously short of water, with more than 70 million hectares of dry farming area, 55% to 65% of the annual precipitation is evaporated, agricultural production is seriously affected, and the ecological environment is deteriorating day by day. [0003] According to the relevant research results released by the Ministry of Agriculture's "Research Report on Fertilizer Utilization Efficiency of my country's Three Major Grain Crops", the current season average utilization rates of nitro...
