Abstract

The invention discloses a carbon-based high-phosphorus special fertilizer for Pinus massoniana Lamb.. The special fertilizer comprises the following effective components in percentage by mass: 4-8% of N, 9-18% of P2O5, 6-12% of K2O, 12-20% of carbon, 7-21.25% of an organic material, 1.0-3.0% of tea saponin, 0.0-0.4% of Zn and 0.0-0.2% of B. The special fertilizer can fully meet the nutritional demand of a Pinus massoniana Lamb. forest in Guangxi, can improve the yield and the quality of Pinus massoniana Lamb., can also improve the soil pH, fix soil aggregate, maintain moisture seepage and assist in moisture exchange, can regulate phosphorus nutrients in soil and enables the soil nutrients to be at equilibrium values. Moreover, the fertilizer utilization ratio can be improved, the soil water and fertilizer retaining capability is improved, the fertilizer wastage rate is reduced, and fertilizer application reduction and efficiency improvement and environmental pollution control are positively promoted.

Description

technical field [0001] The invention relates to the field of compound fertilizers in forestry production, in particular to a carbon-based high-phosphorus special fertilizer applied to masson pine. Background technique [0002] Masson pine (Pinus massoniana Lamb) is one of the most important industrial timber species unique to subtropical regions in my country. It is the main tree species for afforestation in various provinces and regions in southern my country. The native tree species with the widest, largest area, wide range of uses, and the highest degree of comprehensive utilization of the whole tree. The main producing areas are Zhejiang, Fujian, Jiangxi, Hubei, Hunan, Sichuan, Guizhou, Guangxi and Guangdong. Shaanxi, Henan, and Jiangsu are mainly distributed in their southern regions, Anhui is distributed in the central and southern regions, Yunnan, Guangnan and Funing in southern Henan, and the low mountains in northern Taiwan, and a small amount of sporadic distributi...
