Embodiment 1

[0028] In 2019, at the nursery base of Tengchong Safflower Camellia Test Station, Tengchong County, Baoshan City, Yunnan Province, the present invention was used to fertilize 5-year-old Tengchong Safflower Camellia container seedlings (seedling height 65cm, ground diameter 1.1cm), and the specific technical method of the invention adopted As follows: In March, the method of hole application was adopted, and each plant was applied with 25 grams of mixed fertilizer with a ratio of N-P2O5-K2O-MgO-CaO of 7-2-5-2-5, and the fertilization depth was 15cm. After one year, the investigation, The results show that the height of the seedlings fertilized by the present invention is 109 cm, and the ground diameter is 1.9 cm, which are respectively increased by 23.5% and 11.8% compared with the control.

Embodiment 2

[0030]In 2019, at the Tengchong safflower camellia planting base in Houqiao Town, Tengchong County, Baoshan City, Yunnan Province, the present invention was used to fertilize 8-year-old Tengchong safflower camellia. The specific technical methods of the present invention were as follows: on March 12 and July 13 Day, adopt the method of furrow fertilization (fertilization depth 25cm), apply 250g of mixed fertilizer with N-P2O5-K2O-MgO-CaO ratio of 7-2-5-2-5 per plant, the survey results in September 2019, 12 Investigate the growth of the tree in the month, the results show that the plant height and ground diameter of the fertilized plants of the present invention have been improved by 17% and 11% respectively compared with the contrast. Yield increased by 15%.

Embodiment 3

[0032] In 2019, the germplasm resource bank of the Tengchong Safflower Camellia Experimental Station in Tengchong County, Baoshan City, Yunnan Province adopted the present invention to fertilize and manage the 40-year-old Tengchong Safflower Camellia oleifera. On the 15th of May, adopt the method of furrow fertilization (fertilization depth 25cm), and apply 600-800g of mixed fertilizer with N-P2O5-K2O-MgO-CaO ratio of 7-2-5-2-5 per plant, September 2019- The amount of investigation results in October, and the investigation of the crown width of the tree body in December, the results show that the crown width of the fertilization of the present invention has been improved by 15%, and the output has increased by 20%.

Abstract

The invention discloses a formula and an application method of a special fertilizer for Camellia reticulate Lindl. in the technical field of fertilizers. The method comprises the following steps of: mixing N-P2O5-K2O-MgO-CaO according to a mass ratio of (7-2-5-2-5); the application method of the special fertilizer formula for the Camellia reticulate Lindl. comprises the following steps of: furrowapplication is conducted in the first ten days of March and the middle ten days of July, fertilization furrows with the depth being 20 cm or above and the length being 50 cm or above are dug 5-10 cm away from the outer portion of the water drip line of the crown. The fertilizer is evenly applied into the furrows, soil returning and compaction are conducted, and the fertilization amount is increased year by year from small to large according to the tree age; and the adult trees are calculated according to the crown breadth area of 150-200g / m < 2 >. The fertilizer is more balanced in nutrition proportion, fertilization is performed by combining key nodes of nutrition requirements, the utilization efficiency of the fertilizer is higher, the cost can be reduced by more than 10%, the economic yield can be promoted to be obtained one year in advance, the yield is increased by 32.5%, growth of forest establishment tree bodies is promoted, and the yield is increased by more than 15%.
