Problems solved by technology

[0003] In the 1950s, slash pine began to be introduced into my country. In the 1970s, it was introduced on a large scale and performed well. With the rapid development of slash pine pulp and papermaking, the market demand for improved varieties of slash pine seed gardens is increasing. In order to improve the quality of slash pine The seed yield of the seed garden and the development of the special fertilizer for the slash pine seed garden are of great significance, but there are no reports at home and abroad on the special fertilizer for the slash pine seed garden

preparation example Construction

[0018] The preparation method of slash pine seed garden fertilizer specifically carries out according to the following steps:

[0019] Weigh 70-80 parts of chicken manure, 0.01-0.2 parts of fermentation agent, 2-8 parts of urea, 10-15 parts of calcium magnesium phosphate fertilizer, 1-5 parts of potassium sulfate, 0.05-0.5 parts of borax, Zinc 0.05-0.5 parts, then mix and stir all the raw materials, transport them to the fermentation tank for fermentation, after the fermentation is completed, transport them to the twin-screw extrusion granulator, extrude them into cylindrical granules, and pack them into finished products after drying .

[0020] Among them, during the fermentation process, it is turned every 1-2 days, and aerobic fermentation is carried out. The fermentation time is 10-15 days in summer and 20-25 days in other seasons. The fermentation temperature is about 65°C, and the water content of granulation is about 12%.

[0021] The slash pine seed garden fertilizer ...

Embodiment 1

[0024] 75 kg of chicken manure, 0.1 kg of fermentation agent, 4 kg of urea, 13 kg of calcium magnesium phosphate fertilizer, 2 kg of potassium sulfate, 0.3 kg of borax, and 0.25 kg of zinc sulfate. First dry the chicken manure, crush it, adjust the humidity and add the fermentation agent Fully mixed and fermented, then dried, and then directly mixed with the above-mentioned urea, calcium magnesium phosphate fertilizer, potassium sulfate, borax, and zinc sulfate.

[0025] It should not be in direct contact with the roots or leaves of slash pine during use. The application rate is 3000 kg / ha.

[0026] Apply this special fertilizer to the wetland pine seed garden (Quaternary red soil) in Taolin Forest Farm, Miluo City, Hunan Province, and mix it with compound fertilizer (produced by Stanley Company, N, P 2 o 5 、K 2 O content was 15%, 15%, 15%) for comparison. The results are listed in table 1

[0027] Table 1 Statistical table of fertilization test results in the second-gene...

Embodiment 2

[0030] 70 kg of chicken manure, 0.2 kg of fermentation agent, 2 kg of urea, 15 kg of calcium magnesium phosphate fertilizer, 1 kg of potassium sulfate, 0.5 kg of borax, and 0.05 kg of zinc sulfate. First, dry the chicken manure, crush it, adjust the humidity and add the fermentation agent Fully mixed and fermented, then dried, and then directly mixed with the above-mentioned urea, calcium magnesium phosphate fertilizer, potassium sulfate, borax, and zinc sulfate.

[0031] It should not be in direct contact with the roots or leaves of slash pine during use. The application rate is 3000 kg / ha.

[0032] Use this special fertilizer to apply to Hunan Taoyuan Swamp Pine Second Generation Seed Garden (Quaternary Red Soil), and compare it with compound fertilizer (same as above). The results are listed in Table 2

Abstract

The invention discloses a slash pine seed orchard fertilizer and a preparation method thereof. The method comprises the steps of weighing the following raw materials in parts by weight: 70-80 parts of chicken manure, 0.01-0.2 part of a fermentation preparation, 2-8 parts of urea, 10-15 parts of calcium magnesium phosphate, 1-5 parts of potassium sulfate, 0.05-0.5 part of borax and 0.05-0.5 part of zinc sulfate; mixing and stirring the raw materials, conveying the mixture to a fermentation tank for fermentation, and conveying the product to a twin-screw extrusion granulator after fermentation is completed; and extruding the product into cylindrical particles, and drying and packaging the particles to form the finished product. The anti-adversity abilities of drought resistance, cold resistance and disease resistance of slash pine are improved, and the yield is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, and relates to a fertilizer for slash pine seed gardens and a preparation method thereof. Background technique [0002] Slash pine (Pinus elliottii Engelm var.) is a large evergreen tree with a height of 40 meters and a diameter at breast height of more than 1 meter in the country of origin in the United States. When slash pine was introduced on a high stand in Taolin Forest Farm, Miluo City, when it was 23 years old, The tree is 18 meters high and 38 centimeters in diameter at breast height. The bark of Swamp pine is taupe or dark red, longitudinally cracked, rough and peeled off in large scales, the trunk is straight and full, the crown is egg-shaped, the branches grow in 2 to several rounds every year, the branchlets are thick, orange-brown to taupe, winter buds Reddish brown, cylindrical, without resin. Coniferous needles coexist in bundles of 2-3 needles, most of them fall off...
