Method for rapidly fertilizing newly reclaimed camellia oleifera young forest land red in soil hilly region

Abstract

A method for rapidly fertilizing a newly reclaimed camellia oleifera young forest land in a red soil hilly region comprises the following steps: (1), a fertilized forest land is selected: an acid-soil slope with the slope degree lower than 25 degrees is selected on a sunny slope or a half-sunny slope of the red soil hilly region for building a camellia oleifera forest land serve as a rapid fertilizing object; (2), full reclamation of terraced soil is performed, and grass is planted on terrace walls for protection; (3), two seasons of grass or green manure are planted or applied each year. The method has the functions as follows: water and soil loss of the newly reclaimed camellia oleifera young forest land in the red soil hilly region in the south is prevented and controlled, the physical and chemical properties of soil are improved, the newly reclaimed camellia oleifera young forest land in the red soil hilly region is rapidly fertilized, and camellia oleifera growth is promoted.

Description

technical field [0001] The invention relates to a method for rapid fertilization of camellia oleifera woodland, in particular to a method for rapid fertilization of camellia oleifera young forest land reclaimed in red soil hilly areas. Background technique [0002] The red soil in the Jiangnan region of China is distributed in the hills below 300m above sea level and the lower part of the low mountains below 500m above sea level, with a large area, 773.33×10 4 h㎡(1.16×10 8 Mu), accounting for 46.3% of the total land area of ​​the province; Hunan Province has 863.72×10 4 h㎡(1.29×10 8 Mu), accounting for 40.8% of the total land area of ​​the province. The area has abundant light and temperature, abundant water and soil reserve resources, and a wide variety of plant resources. It is a main area of ​​agriculture, forestry and animal husbandry production. [0003] The development and utilization of red soil resources, that is, the development and utilization of red soil reser...

Problems solved by technology

[0006] There was a report 50 years ago about green manure interplanting in newly reclaimed red soil juvenile camellia oleifera forests [Li Zhenji. The experience of interplanting garden flowers to promote Camellia oleifera and grain production [J]. Forestry Practical Technology, 1966, (19: 34-40 )]; but intercropping pastures have not been reported, and only winter green manure is interplanted, and limited by conditions, the biomass of green manure is not high, and the effect on fertilizing soil is limited
