Compound fertilizer special for commercial forest of Toona sinensis

Abstract

The invention relates to a compound fertilizer special for commercial forest, in particular to a compound fertilizer special for commercial forest of Toona sinensis. The compound fertilizer is prepared from, by weight, 20-50 parts of humus soil, 5-30 parts of bio-organic fertilizer, 1-5 parts of microelement fertilizer, and 30-70 parts of macroelement fertilizer. The macroelement fertilizer comprises nitrogenous fertilizer, phosphatic fertilizer and potassic fertilizer by the weight ratio of (15-30): (16-20): (11-13), and further, the weight ratio of the effective constituents N, P2O5 and K is equal to (11-14): (4-5): (6-8). The microbial active flora of the bio-organic fertilizer is greater than two hundred millions, and each gram of the bio-organic fertilizer contains 20-40 billions of organic active bacteria. The compound fertilizer meets nutrient requirements of commercial forest of Toona sinensis, and further, by application of the bio-organic fertilizer, the C and N ratio of soil is optimized, beneficial microbial flora is increased, and utilization of the fertilizer and yield of the commercial forest of Toona sinensis are both increased.

Description

technical field

[0001] The invention relates to a special compound fertilizer for timber forests, in particular to a special compound fertilizer for Chinese toon forests. Background technique

[0002] Toona sinensis, also known as Toona sinensis, belongs to the perennial deciduous tree of the family Meliaceae Toona. Toona sinensis has a long history of cultivation in my country. It is not only a unique fast-growing timber tree species in my country, but also called "green health food" abroad. Toona sinensis has strong adaptability and is easy to cultivate. It can grow in subtropical or warm temperate regions with an average temperature of 8-12°C and annual precipitation of 600-800m, and can be vertically distributed in high mountains up to 1800m.

[0003] The high edible value and medicinal value of Chinese toon have been loved by consumers. Chinese toon is a unique tree vegetable in my country. According to research, Chinese toon contains more protein, amino acids, variou...

Examples

Embodiment 1

[0027] Urea [CO(NH 2 )] 15kg, superphosphate [Ca(H 2 PO 4 ) 2 ·H 2 O] 17kg, potassium sulfate [K 2 SO 4 ]13kg, bio-organic fertilizer 20kg, ferrous sulfate [FeSO 4 ·7H 2 O] 1.5kg, zinc sulfate [ZnSO 4 ·7H 2 O] 0.5kg, humus soil 33kg.

[0028] The above components are mixed evenly, and the special compound fertilizer 1 for Chinese toon forest is prepared by pelletizing by pelletizing equipment, drying and other steps.

Embodiment 2

[0030] Urea [CO(NH 2 )] 20kg, calcium superphosphate [Ca(H 2 PO 4 ) 2 ·H 2 O] 20kg, potassium chloride [KCl] 12kg, bio-organic fertilizer 10kg, ferrous sulfate [FeSO 4 ·7H 2 O] 1.5kg, zinc sulfate [ZnSO 4 ·7H 2 O] 0.5kg, humus soil 36kg.

[0031] The above components are mixed evenly, and the special compound fertilizer 2 for Chinese toon forest is prepared by pelletizing by pelletizing equipment, drying and other steps.

Embodiment 3

[0033] Urea [CO(NH 2 )] 30kg, calcium superphosphate [Ca(H 2 PO 4 ) 2 ·H 2O] 16kg, potassium chloride [KCl] 11kg, bio-organic fertilizer 10kg, ferrous sulfate [FeSO 4 ·7H 2 O] 2kg, zinc sulfate [ZnSO 4 ·7H 2 O] 1kg, humus soil 30kg.

[0034] Mix the above components evenly, and prepare the special compound fertilizer 3 for Chinese toon timber forest through the steps of pelletizing by pelletizing equipment and drying.

[0035] 2. Test process

[0036] The fertilizer effect test of the compound fertilizer of the present invention is selected in Junlian County, Sichuan, and Lezhi County Chinese toon forest for promotion and application, and the experimental process is as follows:

[0037] In Junlian County and Lezhi County, Toona sinensis timber forest lands were selected to carry out experiments with relatively consistent bamboo forest structure and growth conditions. The phylogenetic age of the forest land was 3-4 years old, and the soil pH value was between 6-8.
