A kind of blended slow-release urea bb fertilizer specially used for Hami melon

Abstract

The invention discloses a blended slow-release urea BB fertilizer specially used for Hami melon. The fertilizer is composed of three different urea components A, B and C, which are compounded and compatible with a set phosphate fertilizer, potassium fertilizer or compound fertilizer. A is common urea, component B and component C are urea + NAM additive, and the weight ratio among component A, component B and component C is (1-2):(3-4):(4-6 ), wherein, the weight of the NAM additive in component B is 5‰ of the pure nitrogen content in the component A urea; the NAM additive in the component C is 8‰ of the pure nitrogen content in the component A urea; The ratio of content to total nitrogen in slow-release urea BB fertilizer is (0.75-1): (1.6-2); the amount of potassium fertilizer added is the ratio of available potassium content to total nitrogen in slow-release urea BB fertilizer (0.75-1):( 1.6-2). The fertilizer has good application effect, high urea utilization rate, simple production process and wide application value.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer preparation. Specifically, the present invention relates to the technical field of a urea slow-release fertilizer and its preparation. Further, the present invention relates to the technical field of the preparation of a special blended slow-release urea BB fertilizer for Hami melon. Background technique [0002] The scientific name of Hami melon is muskmelon, which is a famous and high-quality specialty product in Xinjiang, China. The fruit of Hami melon produced in Xinjiang is rich in nutrition and good in quality. The fruit has bright color, beautiful texture, sweet taste, strong fragrance and excellent flavor. The best among them have always been favored by consumers, and their products are sold all over the country and exported to many countries.

AI Technical Summary

Problems solved by technology

Nitrogen fertilizer is an important factor that determines the yield and quality of crops. It is also the chemical fertilizer used in the largest amount in agricultural production. The annual amount is still increasing, but the utilization rate of nitrogen fertilizer has been very low. The low utilization rate of nitrogen fertilizer not only leads to the benefit of increasing production Reduced production costs, increased production costs, and caused a series of ecological and environmental pollution and other issues, please refer to the attached literature

[0003] At present, scholars at home and abroad have proposed different methods and approaches for improving nitrogen use efficiency, such as nitrogen fertilizer base application, drip application with water, and research and development of slow / control nitrogen fertilizers, etc., but there are still many problems because crops have their own unique needs. Fertilizer law, a slow-release fertilizer cannot be widely used in various crops
