Dedicated watermelon set water-soluble fertilizer and preparation method thereof

Abstract

The invention discloses a dedicated watermelon set water-soluble fertilizer which is prepared from a vine growing fertilizer and a fruit expanding fertilizer, wherein the vine growing fertilizer is prepared from the following raw materials in parts by weight: 400 to 520 parts of potassium nitrate, 250 to 350 parts of urea, 20 to 120 parts of monopotassium phosphate, 5 to 200 parts of monoammoniumphosphate, 27 parts of boric acid, 10 to 100 parts of magnesium sulfate, 5 parts of chelated zinc, 2 parts of chelated copper and 2 parts of chelated iron; the fruit expanding fertilizer is prepared from the following raw materials in parts by weight: 650 to 670 parts of potassium nitrate, 100 to 130 parts of urea, 10 to 100 parts of ammonium phosphorus nitrate, 90 to 110 parts of monoammonium phosphate, 10 parts of boric acid, 10 to 100 parts of magnesium sulfate, 5 parts of chelated zinc, 2 parts of chelated copper and 4 parts of chelated iron. The dedicated watermelon set water-soluble fertilizer and a preparation method of the dedicated watermelon set water-soluble fertilizer disclosed by the invention are matched with the watermelon nutrition absorption characteristics, so that watermelon nutrition requirements can be met, watermelon yield is improved, and watermelon quality is improved; the fertilizer use amount is effectively reduced, application of a water-fertilizer integration technology is promoted, and the purposes of saving water and saving fertilizers are achieved.

Description

technical field [0001] The invention belongs to the field of fertilizers for crops, and in particular relates to a special set water-soluble fertilizer for watermelons and a preparation method thereof. Background technique [0002] my country is an important producer and consumer of watermelon. According to the statistics of FAO, the total output of watermelon in my country accounts for more than 65% of the total output in the world. Watermelon planting is widely distributed in my country, wherein the Huanghuaihai (spring and summer) region and the Yangtze River Basin (summer) are the dominant production areas of watermelon in my country, and the output and sowing area of ​​watermelon account for more than 70% of the country. In recent years, the intensification and scale of watermelon production in my country has gradually expanded, and the application of water and fertilizer integration technology in watermelon production has become more and more common. Therefore, designi...

Problems solved by technology

[0004] Patents CN103992160A and CN104130047A respectively announced a special fertilizer for watermelon, but these special fertilizers for watermelon are mainly used as base fertilizer, and the nutrient absorption of watermelon increases rapidly after fruit setting, so the published special fertilizer for watermelon is difficult to meet the nutrient demand of watermelon in the later stage

In actual production, due to the lack of watermelon water-soluble fertilizer products on the market, watermelon production mainly adopts the method of one-time base fertilizer fertilization, and problems such as excessive fertilization, nutrient imbalance, and low fertilizer utilization rate are prominent, resulting in a decline in watermelon yield and quality, and soil secondary growth. Salinization and environmental pollution seriously restrict the sustainable development of watermelon production in my country
