Description
Technical field
The utility model relates to a kind of agricultural machinery, refers in particular to the potato ridge film trench planting sowing associating unit of farm work.
Background technology
Plastic mulching crop genetics is a protection ground new cultivation technology of wideling popularize; be used for the condition that partly controls environment; creation is suitable for the cultivation method of the microclimate of plant growth, can promote crop precocity, high yield, high-quality, has significant economic benefit.Film-mulching technique originates from the fifties in last century, is suitable for abroad the crop of small size intensive cultivation for horticultural gardening, vegetables etc., develops in field crop cultivating again afterwards.Plastic film mulch technology develops into planting after plastic covered integration of operation from artificial plastic film mulch, on whole kind bed well, spreads with plastic film, and while seeding and fertilizing etc.Promoted the use of in the cultivation of cotton, peanut, tobacco, corn, beet etc.
The mode of existing machinery plastic film mulch and sowing has three kinds:
1, after first plastic film mulch, sow: the first ridging in whole good ground, and carry out spraying herbicide, then use film-laying machine spreading, until ground temperature rises, arrive sowing time, with dibbler program request and earthing on film.This is the method that current China uses more generally.
2, first after planting plastic film mulch: on certain areas and farm, be limited to and there is no applicable plastic-film mulch seeder tool, in sowing time, with conventional sower, by agrotechnical requirement, first seed is sown in soil, and then with film-laying machine, spreads mulch film, after emerging, by artificial rupture of membrane, by spacing in the rows, put seedling.This method labour intensity is large, and work efficiency is low.
3, planting after plastic covered integration of operation: in sowing time, once complete the operations such as whole ground, fertilising, spray herbicide, plastic film mulch, sowing, earthing and suppression with mulch film spreading and seeding machine.Mechanization degree is higher, better economic benefit.With facility, an one-stop operation, complete multi-mode operation technique, it have shorten inter process every and duty cycle, improve operating efficiency; Reduce tractor and enter ground number of times, alleviate machinery to soil packing, etc. advantage, there is obvious comprehensive benefit.
In European and American developed countries, potato setter is through development and the application of decades, and its technical merit has reached quite perfect degree, no matter is operating speed, production efficiency, service behaviour, seeding quality, or versatility and the adaptability aspect of seeding machinary, all more advanced.The 1700 type potato combined sowing units that U.S. promise 1220 types of 2 row 2CMFD-Z types, 2MSB-1 type, middle machine, 1240 types and the Germany producing as American-European countries produces all can once complete the operations such as fertilising, sowing, ridging, overlay film, suppression, earthing.But these more ripe Sowing machine for potatoes are expensive, cost of investment is high, and complex structure, the agriculture requirement that can not adapt to China's plantation operation having, such as ridging line-spacing, seat water spot kind, ridge film ditch sowing planting operation etc.
In recent years, integration of operation and wide cut, the same developing direction that is considered to agricultural production process all-round mechanization farm machinery of high speed operation.China has developed diversified forms of association work tool.Sowing machine for potatoes is just constantly improved and optimizes.The Sowing machine for potatoes of production definition, all can once complete the operations such as trench digging, sowing, fertilising, ridging, overlay film, suppression of soil at present.The technology that they adopt seed manure to give, reduces the damage of fertilizer to potato seed; The most of seeding parts that adopt chain elevator spoon formula or clamping chain spoon formula seeds elimination structure of facility, plants more evenly, and leakage potato rate and replay rate are lower; The seeding monomer of facility, fertilising parts, earthing parts and suppression parts are all adjustable, can adapt to different line-spacing planting requirements.But China's Sowing machine for potatoes still exists that power consumption is large, production efficiency is low, and reliability and adaptability are poor, is particularly not suitable with the shortcomings such as new agricultural process, new technology requirement of ridge, dry farming area film ditch sowing planting water saving.
