Embodiment 1
[0027] In November 2011, the moderately rocky desertified mountainous land in Linlin Village, Taiping Town, Pingguo County, Guangxi was selected as a mixed forest of Rendou and Dalbergia japonica, and the plantation rate was 1400 trees / hm 2 The density of the artificial partial digging pits and site preparation, first shovel clean the weeds within 1.2m around the planting pits, the digging specifications are 40cm x 40cm wide, 30cm deep, 300g calcium magnesium phosphate fertilizer and 20g city Sell the water-retaining agent, and mix it with the topsoil and return it to the pit. In February 2012, the vigorous and lignified Rendou container seedlings born in May were selected for afforestation. The height of the seedlings was 40 cm and the ground diameter was 0.4 cm. Water the seedlings thoroughly before raising the seedlings, trim the seedlings when raising the seedlings, keep the upper 4~5 compound leaves, and trim 1 / 2 of the end of each compound leaf that remains to reduce w...

[0030] In the spring of 2010, the medium rocky desertification mountainous area of Bale Village, Taiping Town, Pingguo County, Guangxi was used as a mixed forest of Rendou and Dalbergia japonica, and 1100 plants / hm were planted on the forested land 2 The density of the artificial partial digging pits and site preparation, first shovel clean the weeds within 1.2m around the planting pits, the digging specifications are 40cm x 40cm wide, 30cm deep, 300g calcium magnesium phosphate fertilizer and 20g city Sell the water-retaining agent, and mix it with the topsoil and return it to the pit. In February 2011, half-year-old robust lignified Rendou container seedlings were selected for afforestation, with a seedling height of 45 cm and a ground diameter of 0.5 cm. Water the seedlings thoroughly before raising the seedlings, trim the seedlings when raising the seedlings, keep the upper 4~5 compound leaves, and trim 1 / 2 of the end of each compound leaf that remains to reduce water ...
