Embodiment Construction

[0008] Technical scheme of the present invention is as follows:

[0009] Disease-preventing Shandong peanut-specific controlled-release fertilizer, the raw material components are as follows:

[0010]

[0011] The humic acid-coated urea and humic acid-coated calcium chloride are sprayed with a layer of binder outside the granular urea or granular calcium chloride, and then sprayed with a layer of air-dried and pulverized weathered coal, and repeat the above process after curing. Until the weathered coal accounts for 5% of the mass of granular urea or granular calcium chloride, the binder accounts for 1% of the mass of granular urea or granular calcium chloride. Preferably, the binder is made by mixing epoxy resin and triethylenetetramine at a mass ratio of 1:0.10-0.12.

[0012] Humic acid-coated urea and humic acid-coated calcium chloride are commercially available products, which are sold by Shandong Jinzhengda Ecological Engineering Co., Ltd., and can also be disclosed a...

Abstract

The invention relates to a disease-preventing type special controlled-release fertilizer for Shandong peanuts as well as a preparation method and application thereof. The disease-preventing type controlled-release fertilizer is prepared from the following raw materials: humic acid coated urea, humic acid coated calcium chloride, sulfur-polymer coated urea, diammonium phosphate, granular potassium chloride, zinc sulfate, boric acid, thiodiazole-copper preparation, carbendazim preparation and fenamiphos granular formulation. The release and proportioning of nutrients in the controlled-release special fertilizer for Shandong peanuts are suitable for nutrient conditions and peanut absorption requirements of soil in main peanut production areas in Shandong, and simultaneously, medicaments for preventing and controlling main diseases such as peanut stem rot, root rot, bacterial wilt, root-knot nematode and the like are added. When peanuts are seeded, the disease-preventing type special controlled-release fertilizer for Shandong peanuts is applied for one time, so that labor and time are saved, and disease-preventing and yield-increasing effects are good.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer, in particular to a disease-prevention special controlled-release fertilizer for Shandong peanuts and its preparation method and application, belonging to the technical field of production and application of controlled-release fertilizers. Background technique [0002] Shandong is a traditional large peanut planting province, with a planting area of ​​more than 10 million mu, accounting for more than 20% of the national planting area. Peanuts in Shandong Province are mainly planted in the Jiaodong hills and the central and southern mountainous areas of Shandong. The soil in the peanut planting area is mostly coarse sand and gravel soil formed by the weathering of granite and gneiss. Compared with Henan, the second largest peanut producing province in my country, and Hebei, the third major producing province, the soil in the main peanut producing area of ​​Shandong Province is affected by...
