Problems solved by technology

[0003] For a long time, due to unreasonable forestry management measures, such as mountain smelting and continuous fir planting, etc., the land fertility of fir forests has declined, and the production of forest trees has declined. In order to achieve the purpose of fast growth and high yield, artificial fertilization measures must be used to improve soil nutrients. Proportion
[0004] However, no relevant reports have been found on the use of fertilizers specifically for Chinese fir to improve the yield and quality of Chinese fir

Abstract

The invention discloses a tea saponin containing special fertilizer for cunninghamia lanceolata. The special fertilizer comprises the following effective components in percentage by weight: 5.1-14.2% of N, 6.9-11.7% of P2O5, 7.5-20% of K2O, 8.0-21.25% of organic matters, 1.14-3.0% tea saponin, 0.00-0.46% of water-soluble Si, 0.00-0.37% of Zn, 0.00-0.24% of B and 0.00-0.3% of Cu. The special fertilizer disclosed by the invention can meet the nutrients needed for the growth of the cunninghamia lanceolata planted in Guangxi province, is rich in organic matters, contains tea saponin and trace elements, has the functions of improving the efficiency of photosynthesis, enhancing the disease and insect resistance and the drought resistance of the cunninghamia lanceolata, increasing the utilization rate of phosphorus and improving the soil, releases nutrients slowly and also has the function of comprehensively balancing and regulating the distribution of nutrients in the cunninghamia lanceolata. In addition, the special fertilizer has high utilization rate and has the functions of improving the yield and the quality of the cunninghamia lanceolata.

Description

technical field [0001] The invention relates to the field of compound fertilizers in forestry production, in particular to a tea saponin-containing special fertilizer for Chinese fir. Background technique [0002] Chinese fir (Cuninhamia lanceolata) belongs to the Taxodiaceae family and is an evergreen tree. It is a unique and well-known excellent fast-growing timber tree species in my country. first place. my country's plantation area accounts for 1 / 4 of the world's plantation area, while my country's fir plantation area accounts for 1 / 4 of the country's plantation area. In Shaanxi, Henan, Anhui, Jiangsu, Zhejiang, Fujian, Jiangxi, Sichuan, Chongqing, and Guangdong There are distributions in China, Guangxi, Yunnan and other places, with a long history of cultivation and a vast distribution area. The timber output accounts for 20% to 25% of the country's commercial timber. Therefore, the Chinese fir plantation plays an important role in the supply of timber for my country's e...
