Description
Technical field
The invention belongs to agricultural technical field of cultivation, in particular to a kind of arid area walnut forest land water-retaining method.
Background technique
Walnut(Juglans. spp)It is the important nut in China and woody oil tree species and a kind of light photograph and soil
Wet tree species.As China's rapid economic development and living standards of the people are continuously improved, demand of the urban and rural residents to walnut is got over
Come it is more, production far can not meet its demand.
Yunnan is located in lower latitude plateau, is influenced by atmospheric circulation, and especially winter is controlled by the continent monsoon dried, summer
Wet maritime monsoon prevailing belongs to lower latitude plateau monsoon climate.But control and shadow due to two season of summer in winter by different atmospheric circulations
It rings, precipitation is extremely non-uniform in seasonal and geographically distribution.Usual precipitation all concentrate on annual 6-8 these three
Month, the May for accounting for about the 60% of annual precipitation, especially November to next year is then arid season, and precipitation only accounts for annual 10-
20%, in addition Yunnan water resource infrastructure is weak, in walnut growing area substantially without water conservancy projects, and this season is walnut
Flower bud differentiation period and germination-frondesce stage, when the nutriment in this stage is not supplied, it is incomplete to will cause bud differentiation, sprouts
Bud leaf stretching period is delayed backward, causes later period fruit drop serious, and the problems such as fruit is small, seriously affects walnut yield and product
Matter.
Currently, the drought-resistant water-preserving measure of walnut woods mainly by build reservoir or water storage cellar etc. miniature hydraulic engineering come into
Row manual watering uses the measures such as water-retaining agent when arid biogeographic zone plants seedling to ensure Survival rate of nursery stock, but the investment of these methods is big, cost
Height is difficult to promote and apply.
Summary of the invention
The present invention is because researching and developing a kind of practical walnut woods based on Yunnan Province's climatic characteristic, selection of walnut forestry plants etc.
Ground water-retaining method, walnut forest land soil moisture content can be made to improve 5-10%, flower bud differentiation period and rudiment exhibition to walnut in dry season
The leaf phase is extremely advantageous, improves the yield and quality, and is worth with great promotion and application.
The present invention is realized by following technical proposal: a kind of walnut forest land water-retaining method, it is characterised in that by following each
Step:
(1) when entering rainy season, conventional site preparation is carried out to walnut forest land and is ploughed deeply, control depth of soil preparation is 25-30cm, and presses 2000-
2500kg/ mus of amount application of organic fertilizers；
(2) on the walnut forest land of step (1), radish seed is sowed by 1000-2500 plants/acre of planting density, in radish
Emergence, seedling growth stage routinely carry out the management such as weeding, fertilising, until radish growth is mature；
(3) continue radish is allowed to be retained in walnut forest land soil after radish is mature and not harvest；
(4) when Radish Bolting, erase in time tender flower stalk and blade allow radish without reproductive growth；
(5) enter mid or late December, collect the radish in walnut forest land soil, fertilising is excavated along the forest land of walnut tree crown periphery
The radish of collection and base manure are put into dressing furrow by ditch together；
(6) during the May of late December to second year, from the gradually rotten radish in dressing furrow to soil release moisture and
Nutriment, Walnut Roots promote Growth status, bud point by the moisture and nutriment of the rotten release of soil absorption radish
Change, do sth. in advance Germination to Frondescent, improves walnut yield and quality.
The Turnip Sprouts selection of the step (2) is big with rhizome, growth is rapid, barren-resistant, is suitable in the east of rainy season plantation
The big radish in river.
The fertilising trench depth of the step (5) is 25-30cm, and width is specifically determined depending on storing whole radish and base manure, and
Radish and base manure mass ratio are 2-3: 0.1-0.5, and base manure is conventional farmyard manure.
It erases in time when the Radish Bolting of the step (4) tender flower stalk and blade, when referring to radish growth to November, by it
Biological characteristics influence meeting bolting and bloom, is solid, can consume the moisture and nutriment of its rhizome in this way, it is therefore necessary to smear in time
Except tender flower stalk lobus cardiacus and whole blades, it is not allowed to carry out reproductive growth.
The radish of the step (5) collected in walnut forest land soil, refers in mid or late December, in conjunction with walnut in the autumn
While winter carries out basal dressing, radish is extracted and is put into dressing furrow together with base manure, is filled and be compacted, dressing furrow with soil
Excavation along walnut tree crown periphery, this region are that walnut fibrous root is distributed most intensive place.
The advantages of present invention has and effect: using the above scheme, radish seed can be sowed in precipitation big rainy season, pressed
Routine allows it to grow, and does not harvest after mature, continues that it is allowed to be retained in walnut forest land soil, and erase in time tender flower stalk and blade,
Due moisture and nutriment are saved, into winter, i.e. mid or late December, the radish in walnut forest land soil is collected, along core
Dressing furrow is excavated in the forest land of peach hat periphery, and the radish of collection and base manure are put into dressing furrow together, allows gradually rotten trailing plants
Foretell to soil and discharge moisture and nutriment, then Walnut Roots is allowed to pass through the moisture and nutrients of the rotten release of soil absorption radish
Matter promotes Growth status, bud differentiation, ahead of time Germination to Frondescent, improves walnut yield and quality.Make walnut forest land soil in dry season
Moisture content improves 4-10%, nonirrigated farmland walnut seedling planting survival rate improves 30-50%, walnut output increased 2-5%, and the present invention passes through
In Yunnan Province, vast water lacking rate, agricultural infrastructure weakness producing region are applied and are promoted, and hill farmer is allowed to shake off poverty and set out on the road to prosperity, tool
There are significant economic benefit, ecological benefits, social benefit.
