Embodiment Construction

[0026] specific implementation plan

[0027] This implementation mode includes two parts: preparation example and application example. Before developing this special formula fertilizer for citrus, the purple soil nutrient status and climatic conditions of the citrus orchard in the Three Gorges area of ​​the Yangtze River were systematically investigated and analyzed. formula.

[0028] 1. Investigation and analysis of basic nutrient status in citrus orchards:

[0029] Through the field investigation and sampling analysis of the special soil and tree nutrient status of the citrus orchard in the Three Gorges area of ​​Zigui County, Hubei Province, the nutrient obstacle factors that affect the fruit yield and quality of the orchard were clarified.

[0030] At the end of 2007, the field sampling survey and analysis data of citrus orchard nutrient status in Zigui area are shown in (Table 1, Table 2).

[0031] The results of soil nutrient measurement show that the pH value of the ...

Abstract

The invention belongs to the technical field of fertilizer preparation, in particular to preparation of citrus proprietary formula fertile being suitable for purple shale soil and applications thereof, which is characterized in that the fertilizer comprises the following effective elements according to pure nutrient in weight percent: 14-18% of nitrogen, 8-10% of phosphorus pentoxide, 8-12% of potassium oxide, 8% of humic acid, 0.05-0.08% of pure boron, and 0.6-1% of zinc oxide; or 12-15% of nitrogen, 6-10% of phosphorus pentoxide, 12-15% of potassium oxide, and 8% of humic acid. The citrus proprietary formula fertile is more suitable for citrus orchards in Three Gorge area, and solves the problems of super high citrus density in the area, single fertilizer types, unreasonable fertilizer proportioning, low fertilizer utilization, and decreased output and quality and the like. By the invention, the yield of the Newhall navel orange is increased by 38.53% and 23.04%, the yield of the Robertson Navel orange is increased by 10.68% and 21.14%, and the yield of the Cara Navel orange is increased by 25% and 15.38% for two consecutive years; and the content of fruit vitamin C is improved by 2-5mg/100g, and the fruit commodity is good.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation and utilization, and in particular relates to the preparation and application of a citrus-specific formula fertilizer for purple shale soil. Background technique [0002] As the number one fruit in the world, citrus is the third most traded agricultural product after wheat and corn. In 2004, my country's citrus output was 14.958 million tons, second only to Brazil and surpassed the United States for the first time to become the world's second largest citrus producer. By 2007, the output reached 20.583 million tons, which was on par with Brazil, the world's largest citrus producer. According to statistics in 2008, China's citrus planting area and output both ranked first in the world. At the same time, relevant data show that the average yield of citrus in my country in 2005 was only 9.31t / hm2 per hectare, lower than the average yield of 14.15t in the world. [0003] Zigui, located...
