Abstract

The invention relates to a special controlled-release fertilizer for biological control of soil-borne diseases of watermelons, and a preparation method and application of the fertilizer. The special controlled-release fertilizer comprises biological-control pesticidal fertilizer, sulfurated high-molecular polymer coated urea, humic-acid coated urea, humic-acid coated potassium sulfate and diammonium phosphate in proportion, wherein the biological-control pesticidal fertilizer is formed by compounding and granulating a solid culture, urea and diatomite, and the solid culture is prepared from actinomycetes and pochonia chlamydosporia through solid cultivation in the prior art. The invention also provides the preparation method and the application of the special controlled-release fertilizer for the watermelons. According to the nutrient need rule of the watermelons, the biological-control pesticidal fertilizer is matched with controlled-release nitrogen fertilizer, phosphatic fertilizer and potassic fertilizer, and the special controlled-release fertilizer not only provides a biological disease preventing function to the watermelons, but also enables nutrient release to meet a watermelon absorbing requirement. Field experiments prove that the special fertilizer has a good effect.

Description

technical field [0001] The invention relates to a watermelon special controlled-release fertilizer for biological control of soil-borne diseases, a preparation method and application thereof, and belongs to the technical field of production and application of controlled-release fertilizers. Background technique [0002] my country is the main producer of watermelon, its planting area accounts for more than 50% of the world, and its output is more than 70% of the world's output, ranking first in the world. With the expansion of watermelon planting scale in my country, the occurrence of diseases is becoming more and more serious, which affects the further healthy development of watermelon planting industry. [0003] The so-called soil-borne diseases refer to the general term for the spread of plant diseases using soil as a medium, and the pathogens can survive in the soil for several years. Soil-borne diseases of watermelon mainly include blight, damping-off, root rot, root-k...
