Embodiment

[0039] 1 Planting area requirements

[0040] 1) Climatic conditions: Zhejiang-Fujian hilly areas south of the Huaihe River, north of Nanling, and east of Yichang with an annual average temperature of 18-20°C, the coldest month not lower than 8-10°C, and precipitation greater than 1,500 mm;

[0041] 2) Soil type: red soil, yellow soil, yellow brown soil, paddy soil and other soils are suitable. If the soil salt content in southeast coastal areas exceeds 0.3%, it is not suitable for afforestation.

[0042] 2 cuttings preparation

[0043] 1) Preparation of cuttings: After the fallen leaves of Goji willow stop growing, select three-year-old Goji willow sticks that are well-developed, free from diseases and insect pests, grow near the root, and have a thickness of 2-3cm as seed strips; cut off the cuttings with a length of 20-25cm, and insert them into the ground One end is cut into a 40° oblique incision, and the exposed end is a flat incision, and every 20 spikes are bundled.

Abstract

The invention discloses a biomass energy forest cultivation method for salix integra thumb elfin forest and belongs to the technical field of plant cultivation. The method includes the following steps of 1), planting region selection; 2), preparation of cuttings; 3), cottage forestation; 4), nourish and management; 5), pest control and prevention; 6), yield estimation; 7), harvesting; 8), biomass storage. Salix integra thumb is calculated through the limited steps, survival rate of the cuttings and seedling survival rate can reach more than 95%, and high yield of the biomass energy forest of the salix integra thumb elfin forest is effectively increased.
