Organic and inorganic special compound fertilizer for navel oranges

Abstract

The invention belongs to the technical field of fruit fertilizer preparation, and discloses the preparation of an organic and inorganic special compound fertilizer for navel oranges and application thereof. The fertilizer comprises the following effective elements in percentage by weight in terms of pure nutrient: 13 percent of nitrogen, 8.5 percent of phosphorus pentoxide, 10.5 percent of potassium oxide, 1.6 percent of magnesium, 3.8 percent of sulfur, 0.12 percent of zinc, 0.21 percent of boron, 0.06 percent of molybdenum, and 13 to 15 percent of organic substances, wherein the total nutrient of the organic substances is over 50 percent, and is dry slag after the fermentation of stevia rebaudiana. The navel orange etiolated trees in a fertilizing area using the special compound fertilizer are obviously reduced, have good growth, green leaves, evenly colored fruits and big fruit shapes, 80cm fruits are increased, the weight of a single fruit is improved by over 15 percent, the content of Vc is increased by about 10 percent, and the soluble solid substances are improved by 1 to 3 percent. The compound fertilizer ensures that the yield is increased by over 2,000kg / hm2, and the income per hectare is increased by about 5,000 RMB; and the utilization rates of nitrogen, phosphor and potassium are improved by 5.2 percent, 1.9 percent and 2.7 percent respectively, and the utilization rate of the fertilizer is improved by 10.1 percent.

Description

technical field [0001] The invention belongs to the field of fertilizer technology and the field of fruit tree cultivation technology, and in particular relates to a special organic and inorganic compound fertilizer for navel oranges. Background technique [0002] Citrus is the largest variety of fruit trees in the world, and China is one of the main countries of origin of citrus, with a recorded cultivation history of more than 4,000 years. my country's citrus industry is developing rapidly. In the early 1950s, China's citrus production was only 210,000 tons. In 1982, the output was close to 1 million tons. By 1997, it exceeded 10 million tons. It ranks second only to Brazil and the United States, ranking third in the world's citrus production. . In 2004, the 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. And by 2007, the output reached 20.583 million tons, alrea...

AI Technical Summary

Problems solved by technology

The survey shows that there are the following problems in the management of navel orange fertilizer: (1) The blindness and randomness of fertilization are large, the effect of fertilizer input is poor, and the utilization rate of fertilizer is low

(2) The amount of fertilizer is low, and the proportion of nutrients is not coordinated. It is manifested as heavy nitrogen and phosphorus fertilizer, light potassium and medium and trace element fertilizer, which aggravates the imbalance of soil nutrients.

At the same time, there are still many problems in the application of trace element fertilizers such as boron

(3) The special formula and special formula fertilizer for navel orange are less used, and the industrialization of fertilization starts slowly
