Drought-resisting afforestation method

Abstract

The invention relates to a drought-resisting afforestation method by means of phyllostachys bambusoides bamboo species and belongs to the field of bamboo afforestation. The method comprises the steps of selecting bamboo species; selecting provenance and mother bamboo; selecting appropriate seasons which are March, April and early and middle June; digging and conveying the mother bamboo, wherein the mother bamboo needs to be dug on a sunny day 2-5 days after raining with a method that scourges and roots of the bamboo are cut from the periphery, the mother bamboo needs to be dug with a soil ball with 5-6 groups of branches and leaves reserved, and then the mother bamboo is conveyed; selecting planting land; planting; spreading 5-8g agricultural water-retaining agents in each pre-dug planting hole, placing a soil ball into each planting hole according to a standard that the upper surface of the soil ball is 3-5cm higher than the ground, backfilling surface soil to enable the soil balls to be flush, adding 2-3g water-retaining agents into the backfilled surface soil and pestling till the soil is compact; adding soil till the soil balls are flush and then treading till the soil is compact; preserving soil moisture; mix-planting arbor species, namely planting deep-rooted native arbor species evenly in each mu of the afforestation land. According to the drought-resisting afforestation method by means of the phyllostachys bambusoides bamboo species, the survival rate and preserving rate of bamboo are increased in afforestation of an approximate semi-arid area.

Description

technical field [0001] The invention relates to a drought-resistant afforestation method, in particular to a drought-resistant afforestation method using laurel bamboo species, which belongs to the field of bamboo afforestation. Background technique [0002] Bamboo has well-developed whip roots and is evergreen in all seasons, which has good landscape ecological and economic benefits. However, in my country's irrigated bamboo forest areas where there is drought and little rain in winter, the annual rainfall is generally 700-900mm, and it is concentrated in April-November. Often due to watering difficulties, encountering drought and water shortage and dry and cold wind in winter, they will die from dehydration, resulting in low survival rate and preservation rate. [0003] In this field, there are 1. "Cultivation Method of Bamboo in Northern Region" (publication number CN101438672A), 2. "Cultivation Method of Cold-resistant Bamboo Domestication" (publication number CN1994043)...

Problems solved by technology

However, in my country's irrigated bamboo forest areas where there is drought and little rain in winter, the annual rainfall is generally 700-900mm, and it is concentrated in April-November. Often due to difficulty in watering, encountering drought, water shortage and dry and cold wind in winter, it leads to dehydration and death, resulting in low survival rate and preservation rate.

[0003] In this field, there are 1. "Cultivation Method of Bamboo in Northern Region" (publication number CN101438672A), 2. "Cultivation Method of Cold-resistant Bamboo Domestication" (publication number CN1994043), 3. "Long-distance Introduction and Afforestation Method of Yellow Sweet Bamboo" ( Publication No. CN102499002A) three patents, but they did not solve the problem of dehydration and death of bamboo plants caused by drought soil water shortage and low air humidity
