A kind of water-saving irrigation method of moso bamboo forest

Abstract

The invention discloses a water-saving phyllostachys edulis irrigation method. The water-saving phyllostachys edulis irrigation method comprises the following steps that 1, phyllostachys edulis forest land is selected, and horizontal ditches are dug; 2, PVC pipes with the diameter of 6-8 cm are sawed open from the middles and are respectively divided into two parts to establish horizontal water collecting ditches; 3, fixing columns are evenly distributed and arranged on two sides of each horizontal water collecting ditch in the length direction; 4, water collecting containers are arranged at the lower ends of the horizontal water collecting ditches and are covered with plastic films; 5, old phyllostachys edulis different in ground diameter are selected and are felled at the end of February, stump joints spacers are made through, stumps are fully filled with water every 15-30 days according to the weather condition, and water-saving irrigation is conducted on the phyllostachys edulis. The water-saving phyllostachys edulis irrigation method applies a field runoff field rainwater collecting method to establish an efficient and economical anti-drought technology of a water storage system using phyllostachys edulis stumps as cores, and provides sustainable water supply for phyllostachys edulis water-starved for a long time in middle-slope, upper-slope and remote regions so as to reduce the influence on phyllostachys edulis productivity of extreme or continuous drought.

Description

technical field [0001] The invention belongs to the technical field of plant irrigation methods, and in particular relates to a water-saving irrigation method for moso bamboo forests. Background technique [0002] Bamboo forest water supply is the most critical in the production of moso bamboo forests, but in recent years, the uneven distribution of precipitation in time and space has caused the general reduction of moso bamboo forest production and the decline of bamboo quality, shortening of internodes, and even seriously damaged the moso bamboo forest ecosystem. From July to August 2013, Zhejiang Province experienced more than 40 consecutive days of extreme high temperature and drought weather above 40°C, and a large area of ​​moso bamboo forests died, accounting for 2% of the total area, and even some water supply conditions were better. The moso bamboo forest also has the phenomenon of leaf curling, which affects the photosynthetic productivity of the bamboo forest. Hi...

[0002] Bamboo forest water supply is the most critical in the production of moso bamboo forests, but in recent years, the uneven distribution of precipitation in time and space has caused the general reduction of moso bamboo forest production and the decline of bamboo quality, shortening of internodes, and even seriously damaged the moso bamboo forest ecosystem

From July to August 2013, Zhejiang Province experienced more than 40 consecutive days of extreme high temperature and drought weather above 40°C, and a large area of ​​moso bamboo forests died, accounting for 2% of the total area, and even some water supply conditions were better. The moso bamboo forest also has the phenomenon of leaf curling, which affects the photosynthetic productivity of the bamboo forest

At present, developed areas have begun to try bamboo forest irrigation in the cultivation and management of moso bamboo forests, especially in moso bamboo shoot forests, but the current water management model has a large investment, and there is still a lack of systematic research and effective research on when to irrigate and how to quantitatively irrigate. Theoretical and technical guidance, resulting in a waste of funds, water resources, and energy; especially in extremely arid climates, due to limited water sources, it is very difficult to implement the popular pumping irrigation scheme, and most of the moso bamboo forests basically have no irrigation condition
