Technical field
The present invention relates to fruit tree farming technique fields, and in particular to a kind of to carry out tangerine using liquid manure induction earthworm displacement
The method of garden biology farming.
Background technique
Citrus is one of the fruit tree planted extensively in the world, and China's citriculture is with a long history, and China's citrus produces within 2014
Amount is up to 3.49 × 107T, citrus cultivated area is up to 2.52 × 107hm2.Citrus is perennial evergreen fruit tree, and growth characteristics make
Obtain tangerine Orchard Soil turns over the more difficult progress of work.Currently, some orangeries carry out no-tillage system, but Long-term No-tillage will lead to soil plate
Knot influences Citrus Root growth, aggravates citrus pest and disease damage；Some orangeries are in the ranks ploughed clearly using machinery in tree body, but
It is too many to be easy to hurt root during turning over, causes the slightly withered aging of branch, aerial growth slow, and mechanical can only in the ranks turn over mostly
It ploughs, soil texture between strain can not be influenced.
Earthworm is the primary animal monoid in soil, referred to as " ecological systems engineering teacher ", can by discharging feces, burrowing,
A series of vital movements such as agitation influence soil texture and function.Darwin once pointed out, " plough be mankind's invention best earliest it
One, but before human survival, soil will also be continued ploughing and weeding by earthworm ploughing and weeding by it ".Modern study is also demonstrate,proved
Bright, the formation effect of Soil of Earthworms structure (duct and aggregate) is very big.By taking L.terrestris earthworm as an example, activity shape
At duct every year up to 82.3km/ha.Earthworm can eat daily is equivalent to 5~30 times of self weight of soil, leaves a large amount of earthworm excrement
It is deposited in soil inside native table or soil, these wormcasts have good aggregate structure, can significantly reduce the soil weight, increase
The water holding capacity of strong soil.
The effect of turning over of Soil of Earthworms has obtained extensive understanding, Publication No. CN101731184B
Chinese invention patent discloses a kind of farmland earthworm cultivation and organism farming method, this method describe in farmland
Breeding earthworm and the method for carrying out biological farming.But these existing methods and technology, only with the activity that earthworm is autonomous
Biological farming is realized in big Tanaka.In this course, people is unable to control the activity direction and range of earthworm, therefore is difficult foundation
