Embodiment 1

[0046] Embodiment 1: special controlled-release fertilizer for watermelon, total nutrient: nitrogen, phosphorus pentoxide, potassium oxide content are respectively 18%, 14%, 18%, all are percentage by mass. The raw material components are as follows:

[0047] 4% thermoplastic resin coated potassium nitrate 200kg

[0048] 5% thermoplastic resin coated potassium nitrate 110kg

[0049] 4% thermoplastic resin coated urea 120kg

[0050] 5% thermoplastic resin coated urea 60kg

[0051] Potassium sulfate compound fertilizer 320kg

[0052] Diammonium phosphate 180kg

[0053] Zinc sulfate 5kg

[0054] Borax 5kg.

[0055] The preparation method is that the above-mentioned raw materials are put into a blender and stirred for 5-10 minutes, and fully mixed to obtain the product. Then the mixed fertilizer is sent to the metering and packaging machine for metering and packaging.

Abstract

The invention relates to a special controlled release fertilizer for watermelons and a preparation method thereof. The special controlled release fertilizer is synthesized by 4 percent of thermoplastic resin coated potassium nitrate, 5 percent of thermoplastic resin coated potassium nitrate, 4 percent of thermoplastic resin coated carbamide, 5 percent of thermoplastic resin coated carbamide, potassium sulphate compound fertilizer, diammonium phosphate, etc. The special controlled release fertilizer for the watermelons of the invention is served as a base fertilizer to be applied only one time before sowing without dressing, thus acquiring relatively good yield-increasing effect, improving the utilization ratio of the fertilizer and saving labor and time.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for resin-coated watermelons and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Watermelon cultivation is distributed all over my country. After the mid-1980s, with the improvement of cultivation technology, watermelon production has developed rapidly. Relevant data show that the annual planting area of ​​watermelon in the country was 450,000 hectares in the late 1970s, and reached 1.13 million hectares in the late 1980s, with a total output of 28.86 million tons. It has become the largest producer in the world. In recent years, my country's watermelon planting area has stabilized at about 1.3 million hectares, with a total output of more than 30 million tons. [0003] Watermelon is a potassium-loving crop. Potassium deficiency will cause the growth of watermelon plants to be slow, the stems will be fr...
