Embodiment 1

[0031] Corn compound fertilizer, soybean protein isolate is composed of the following components: urea 40kg, ammonium dihydrogen phosphate 25kg, dipotassium hydrogen phosphate 10kg, potassium dihydrogen phosphate 27kg, straw 23kg, plant ash 16kg, basic carbonate basic zinc sulfate 5kg, rotten 4kg of phytic acid, 7kg of rhizobia agent and 3kg of water retaining agent. Potassium dihydrogen phosphate is obtained by preparing potassium dihydrogen phosphate with wet-process phosphoric acid. In the present invention, it is prepared by the method in "Production of Potassium Dihydrogen Phosphate by Wet Process Phosphoric Acid" (Lei Wu, "Inorganic Salt Industry", Issue 02, 2004). The straw is obtained by using the EM stock solution as a decomposing agent and decomposing through the composting method. The water retaining agent is carboxymethylated cellulose. The raw materials are weighed in proportion, pulverized, passed through a 100-mesh sieve, mixed, and granulated by a biaxial gra...

[0033] Corn compound fertilizer, soybean protein isolate consists of the following components: urea 50kg, ammonium dihydrogen phosphate 37kg, dipotassium hydrogen phosphate 15kg, potassium dihydrogen phosphate 20kg, straw 13kg, plant ash 7kg, basic carbonate basic zinc sulfate 3kg, rotten 8kg of phytic acid, 10kg of rhizobia agent and 6kg of water retaining agent. Potassium dihydrogen phosphate is obtained by preparing potassium dihydrogen phosphate with wet-process phosphoric acid. In the present invention, it is prepared by the method in "Production of Potassium Dihydrogen Phosphate by Wet Process Phosphoric Acid" (Lei Wu, "Inorganic Salt Industry", Issue 02, 2004). The straw is obtained by using the EM stock solution as a decomposing agent and decomposing through the composting method. The water retaining agent is soybean protein isolate. The raw materials are weighed in proportion, pulverized, passed through a 100-mesh sieve, mixed, and granulated by a biaxial granulator...

Embodiment 3

[0035] Corn compound fertilizer, soybean protein isolate consists of the following components: urea 42kg, ammonium dihydrogen phosphate 34kg, dipotassium hydrogen phosphate 11kg, potassium dihydrogen phosphate 23kg, straw 19kg, plant ash 11kg, basic zinc sulfate 4kg, humic acid 6kg , rhizobia agent 8kg and water retaining agent 5kg. Potassium dihydrogen phosphate is obtained by preparing potassium dihydrogen phosphate with wet-process phosphoric acid. In the present invention, it is prepared by the method in "Production of Potassium Dihydrogen Phosphate by Wet Process Phosphoric Acid" (Lei Wu, "Inorganic Salt Industry", Issue 02, 2004).

Abstract

The invention discloses a corn compound fertilizer, which consists of the following components in parts by weight: 40-50 parts of urea, 25-37 parts of ammonium dihydrogen phosphate, 10-15 parts of dipotassium hydrogen phosphate, potassium dihydrogen phosphate 20~27 parts, 13~23 parts of straw, 7~16 parts of plant ash, 3~5 parts of basic zinc sulfate, 4~8 parts of humic acid, 7~10 parts of rhizobia agent and 3~6 parts of water retaining agent. The corn compound fertilizer of the present invention has a variety of different nutritional components, can meet the needs of fertilizers in different stages of the corn growth process, and has good drought resistance and water retention, can effectively reduce fertilizer leaching loss, and improve fertilizer utilization. Thereby reducing the frequency of fertilizer application, and reducing the amount of application, avoiding waste, while avoiding the possibility of causing pollution to the surrounding environment. It is safe and environmentally friendly, and does not pollute soil and groundwater.

Description

technical field [0001] The invention relates to corn compound fertilizer and belongs to the field of special compound fertilizer for crops. Background technique [0002] Corn is the seed of corn, a grass herb plant. According to research, every 100 grams of corn contains 106 kcal of calories, 2.9 grams of cellulose, 4.0 grams of protein, 1.2 grams of fat, 22.8 grams of carbohydrates, and other mineral elements and vitamins. . The crude fiber contained in corn is 4-10 times higher than that of polished rice and refined noodles. Corn also contains a lot of magnesium, which can strengthen the peristalsis of the intestinal wall and promote the excretion of waste from the body. Corn is the largest food crop in China. Corn plays an extremely important role in my country's food security. It is an important feed crop and an important raw material for food, chemical, fuel, and pharmaceutical industries. Therefore, its importance has been highlighted. [0003] In the traditional f...
