Problems solved by technology

[0002] The role of fertilizers in agricultural production is becoming more and more important, but the utilization rate of fertilizers has been very low. The low utilization rate of fertilizers not only causes waste of resources, reduces the economic benefits of agricultural production, but also brings serious environmental problems. People are committed to Many effective methods and approaches have been put forward for the research on improving fertilizer utilization efficiency, such as deep application of nitrogen fertilizer, water belt fertilizer, screening of nutrient-efficient genotype crop varieties, and development of slow / controlled release fertilizers, etc.

Embodiment 1

[0012] The mixed slow-release fertilizer specially used for rose is composed of ordinary urea, phosphate fertilizer, potassium fertilizer and NAM additives, of which ordinary urea (N≥46%) and phosphate fertilizer are superphosphate (P 2 o 5 ≥16%), potash fertilizer is potassium sulfate (K 2 (2≥50%) in parts by weight, available nitrogen content of common urea: available phosphorus content in phosphate fertilizer: available potassium content=28: 17.5: 33.5 in potash fertilizer; NAM additive addition is common urea, phosphate fertilizer and potash fertilizer gross weight 7-9‰, and NAM additives were purchased from Shenyang Zhongke New Fertilizer Co., Ltd.

Embodiment 2

[0043] The special blended slow-release fertilizer for rose is composed of common urea, phosphate fertilizer, potash fertilizer and NAM additives, wherein common urea and phosphate fertilizer are monoammonium phosphate, and potash fertilizer is potassium chloride. The effective nitrogen content of common urea: in phosphate fertilizer Available phosphorus content: available potassium content in potash fertilizer = 3:2:3.5; NAM additive addition amount is 8‰ of the total weight of ordinary urea, phosphate fertilizer and potash fertilizer.

Embodiment 3

[0045] The special blended slow-release fertilizer for rose is composed of common urea, phosphate fertilizer, potash fertilizer and NAM additives, wherein common urea and phosphate fertilizer are diammonium phosphate, and potash fertilizer is potassium and magnesium sulfate by parts by weight. The effective nitrogen content of common urea: in phosphate fertilizer Available phosphorus content: available potassium content in potash fertilizer = 2.5:1.5:3; NAM additive addition amount is 9‰ of the total weight of ordinary urea, phosphate fertilizer and potash fertilizer.

[0046] Take 33.27kg of the above-mentioned blended controlled-release fertilizer, mix it and apply it to 93m 2 In the Chinese rose field, 2.7kg urea, 17.5kg superphosphate and 7kg potassium sulfate are used as the base fertilizer, and then 3.2kg urea is applied in two times; OPT base application is 2.55kg urea, 15.3kg superphosphate, 3.7kg sulfuric acid Potassium and then divided into 2 times respectively topdr...

Abstract

The invention relates to a controlled-release fertilizer, in particular relating to application of a mixing type controlled-release fertilizer used as a special fertilizer for rosa chinensis. The special mixing type controlled-release fertilizer for the rosa chinensis consists of common urea, a phosphate fertilizer, a potash fertilizer and an NAM additive, wherein based on parts by weight, the ratio of effective nitrogen content of the common urea to effective phosphorus content in the phosphate fertilizer to the effective potassium content in the potash fertilizer is (2.5-3.1):(1.5-2):(3-3.5), and the addition amount of the NAM additive is 8 per mill of the total weight of the common urea, phosphate fertilizer and potash fertilizer. The special mixing type controlled-release fertilizer for the rosa chinensis has the advantages of good applying effect, high fertilizer utilization and simple production process, and ensures that labor and time are saved.

Description

technical field [0001] The invention relates to a slow-release fertilizer, in particular to a special blended slow-release fertilizer for roses. Background technique [0002] The role of fertilizers in agricultural production is becoming more and more important, but the utilization rate of fertilizers has been very low. The low utilization rate of fertilizers not only causes waste of resources, reduces the economic benefits of agricultural production, but also brings serious environmental problems. People are committed to In the study of improving fertilizer utilization efficiency, many effective methods and approaches have been proposed, such as deep application of nitrogen fertilizer, water belt fertilizer, screening of nutrient-efficient genotype crop varieties, and development of slow / controlled release fertilizers, etc. Slow-release fertilizers can save 20% to 40% of the amount of traditional fertilizers under the same output, effectively reduce the negative impact of f...
