Embodiment 1

[0031] Mix 25% of ammonium sulfate, 15% of calcium cyanamide, 20% of monoammonium phosphate, 18% of potassium chloride, 10% of phosphoric acid, and 12% of potassium humate through disc granulation to make compound fertilizer A.

[0032] Mix zinc oxide, zinc sulfate, and borax in a ratio of 3.5:1.5:5, grind them, pass through a 200-mesh sieve, and obtain trace element mixture B.

[0033] Wrap the trace element mixture B on the surface of the compound fertilizer A at a ratio of 0.3%, and then spray 0.3% phosphoric acid to obtain the final product compound fertilizer.

Embodiment 2

[0035] Mix 15% of ammonium chloride, 20% of calcium cyanamide, 15% of monoammonium phosphate, 20% of potassium sulfate, 15% of phosphoric acid, and 15% of polyaspartic acid through disc granulation to make compound fertilizer A.

[0036] Mix zinc oxide, zinc sulfate, and borax in a ratio of 3:1:6, grind them, and pass through a 150-mesh sieve to obtain trace element mixture B.

[0037] Wrap the trace element mixture B on the surface of the compound fertilizer A at a ratio of 0.5%, and then spray 0.5% phosphoric acid to obtain the final product compound fertilizer.

Embodiment 3

[0039] Mix 25% of ammonium sulfate, 10% of calcium cyanamide, 25% of monoammonium phosphate, 15% of potassium chloride, 10% of phosphoric acid, and 15% of potassium fulvic acid through disc granulation to make compound fertilizer A.

[0040] Mix zinc oxide, zinc sulfate, and borax in a ratio of 4:2:4, grind them, and pass through a 250-mesh sieve to obtain trace element mixture B.

Abstract

The invention provides a compound fertilizer for preventing and treating a soil-borne disease and a preparation method thereof. The compound fertilizer mainly comprises a nitrogen fertilizer, calcium cyanamide, a phosphate fertilizer, a potash fertilizer, a soil fertilizer maintenance additive and trace elements. The compound fertilizer comprises major elements such as nitrogen, phosphorus, and kalium, middle elements such as calcium and sulfur, trace elements of zinc and boron and further comprises nutrition required by plant growth. After the application of the compound fertilizer, disease resistance of plants is improved obviously, so that a preventing and treating effect on a continuous cropping disease can be played, the purpose of slightly using, even not using agricultural chemicals can be achieved, and products reach the non-pollution standard; the product quality is improved; moreover, the compound fertilizer has a good hardening preventing effect, the preparation method and process are simple, the investment is less, and the benefits are good.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a compound fertilizer for preventing and treating heavy cropping diseases and a preparation method thereof. Background technique [0002] The method of planting the same crop in the same plot year after year is called continuous cropping or double cropping. Heavy crops generally have low survival rate, poor growth, low root activity, poor stress resistance, few fibrous roots, few fruits, low yield, poor quality and short life span. This is now called the problem of heavy cropping in our country, the phenomenon of taboo in Japan, and the problem of replanting or replanting disease in European and American countries. Studies have found that generally watermelons can only be planted again after 7 to 8 years of crop rotation, otherwise they will easily die due to the occurrence of Fusarium wilt and even fail; strawberry cropping for 4 years can reduce the yield by more than 40%. The disease...
