Two horizontal collecting gutters are answered, the collecting container that a volume is 100L is arranged in mao bamboo woods per acre；5) the old bamboo of different ground diameters is selected,
Old bamboo is felled at the end of February, and stump is handled, by stump section every getting through, according to weather condition, every 15-30 days past stumps
Water is inside filled, covers stump open end with plastic film, water-saving irrigation is carried out to mao bamboo woods, wherein stump number is with hair per acre
It is 180-210 plants that bamboo grove mother bamboo, which stays feeding density, and stump internal diameter is in 6-15cm.
Embodiment 1
The research of moso bamboo stump inner wall water absorbing capacity: in the town the Xu Kou village Gao Lian, 30 plants of old bamboo of different ground diameters are selected, in 2 months
Old bamboo is felled at bottom, and handles stump, gets through section every to nearly screw, does not split carefully.Water is filled in each stump, is remembered
Water injection rate and stump number are recorded, uses plastic film sealing, then with vaporization prevention.Per two weeks measures primary remaining water.Specifically
Measurement method: opening sealing film, slowly fill the water in stump, until filling water, records supplemented water, as before
The water absorption of the stump inner wall of two weeks.
The dynamic change of moso bamboo stump inner wall water absorbing capacity: after moso bamboo stump passes through artificial measures, inner cavity retention volume root
325 ml-700ml are respectively reached according to ground diameter size 6cm-15cm.Research is found: moso bamboo stump water absorbing capacity is in monthly total precipitation
Positive correlation is presented with stump ground diameter and its freshness in existing negative correlation.Monthly total precipitation is few, and relative air humidity reduces, soil
Water content reduces, and declines moso bamboo root system water supply capacity, and stump water absorbing capacity increases instead, to meet moso bamboo individual growth
It needs.The water supply capacity of moso bamboo stump inner cavity increases with the increase of ground diameter, this may be related with the size of its cavity wall surface area.
Stump freshness also influences the water absorbing capacity of stump inner wall, although the precipitation such as March is very abundant, because stump is fresh,
The water absorbing capacity of inner wall is apparently higher than other months.Relatively from the stump inner wall water absorbing capacity in four seasons after felling,
It was found that with the aging of stump, water absorbing capacity is also decreased.The moisture storage capacity of moso bamboo stump is generally related with ground diameter rugosity, phase
With height is felled, ground diameter is thicker, and moisture storage capacity is more.The stump moisture storage capacity of general path moso bamboo is in 300ml or more, major diameter moso bamboo
Stump moisture storage capacity can reach 700ml or so.Moso bamboo stump stores up the water supply that can guarantee the long period after full water, and general season can be
20 days or more, hot-dry season can also be supplied 15 days or more.
Embodiment 2
The relationship of stump quantity and mao bamboo woods productivity: in Shangguan township, Sheng Cun selects density for 150-170 plants/acre or so
, gradient 20-30 degree, the similar mao bamboo woods of stand structure, setting up area is 20m × 20m(400m2) 12 samples, be divided into 3
Group, peripheral 4 points of setting spud piles have 10 ~ 15 meters of isolation strip between sample ground, and every group of sample are numbered, and progress difference is cut down
Influence research of the stake quantity to bamboo productivity.Every group of stump processing number is 0 plant, 15 plants, 30 plants, 45 plants/acre.Each stump
Water is inside filled, according to weather condition every 15-30 days plus water 1 time, other Operation Measures were carried out according to national standard.In July, 2013 investigation
Every sample current year Newculms, rugosity, internode away from factors such as (eyebrow enclose place)；2014-2015 year repeats on the basis of as former state
Observation is primary, and the end of the year 2013 cut down old bamboo, with making every sample density of bamboo forest complex experimental designs, and in July, 2015 carries out Hsinchu investigation.
It can be seen that by 13-15 position observation and intuitive analysis result and be shown in Table 1-2, stump handles with sample slope
It is influenced to equal factor pairs moso bamboo Newculms and big-diameter wood ratio obvious.Wherein, moso bamboo Newculms are embodied with stump number
Amount increases and increased trend, and more with 45 plants/acre of stump processing Newculms, illustrating forest land stump and be aided with moisturizing processing can
To improve standing forest water supply conditions, especially under the conditions of summer and autumn seasonal drought, and at this time it is mostly the vigorous life of moso bamboo underground bamboo whip
Long stage, preferable water supply conditions are conducive to Rhizome wood growtht and improve coming year Newculms.Therefore it should be use up in conditional standing forest
Amount increases the quantity of stump, and is aided with artificial water application's measure.

Note: bracket inner digital is big-diameter wood (Mei Jing≤10cm per acre) quantity, ratio, similarly hereinafter
Table 2:15 Newculms and major diameter bamboo wood statistical form (plant/acre)
From the point of view of the panel length of different disposal Hsinchu, be shown in Table 3, stump processing be conducive to Hsinchu internode away from increase, explanation
The improvement of water supply conditions is that advantageously, longer internode is away from the processing benefit for being conducive to improve moso bamboo to moso bamboo Hsinchu Seedling height
With rate.
The long statistical form of the new ring of table 3:13-15
With Global climate change, intermittence arid frequently occurs for south China Phyllostachys Pubescens Distribution Range, to the stable yields of mao bamboo woods
High yield produces adverse effect.It is to solve the important technique measure of intermittence arid, but 90% or more bamboo grove is separate that bamboo grove, which is irrigated,
Water source, therefore, conventional bamboo grove irrigation technique are unable to satisfy the needs of production of bamboo forest.Proposed by the present invention " water storage of moso bamboo stump+
Bamboo grove technology of water catchment " without water source mao bamboo woods water-saving irrigation technique, can solve the status of mountain area water scarcity.
