Abstract

The present invention discloses a kind of precise double line wheat seeding method and corresponding double line seeder, and during seeding wheat, two parallel lines of wheat seeds are spread inside each seed ditch. The double line seeder for precise double line seeding has sowing unit with feed openings in the number doubling that of colters and each of the feed openings has one seed conveying pipe. Each two seed conveying pipes are connected simultaneously to one single colter which forms two seed openings separated with one V-shaped baffle and spaced by 3-5 cm. The precise double line wheat seeding method of the present invention has precise and close seeding and is favorable to raise yield of wheat.

Description

Wheat " two-wire Precision Seeding " method and Precision Seeding machine

Technical field

The invention belongs to proportion of crop planting, relate in particular to the sowing of wheat.

Technical background

At present, wheat seeder all is that each plough is only arranged delegation's seed both at home and abroad, makes the equidistant sowing of seed on a line, is referred to as " single line sowing " mode.For a long time, the research of wheat cultivation theory and culture technique all launches on wheat " single line sowing " mode, as seeding techniques such as " the thick high yield of broadcasting of wheat single line ", " wheat single line light seeding high yield ", " wheat single line Precision Seeding high yields ".Should, these culture techniques all once played the effect of high yield in the different levels of the productive forces or the stage of wheat planting.But improve constantly the restriction bottleneck that traditional wheat cultivation mode has become wheat to achieve higher output along with what wheat yield required.For example, according to " the wheat precision seeding high-yield culture technique " that " single line sowing " mode is founded, be that single wheat seeds are come on the line, every mu of kind amount is controlled at below the 5kg.Though the yield potential of wheat individuality has been brought into play in this single line Precision Seeding, also do not reach the target of super high-yielding.Because with this technology plantation large spike wheat breed, result's rational mu of spike number of grow not go out; As planting the multi-spike-type wheat breed, the result can not grow rational fringe heavily.Therefore, be sought after inventing again a kind of new wheat planting method.

Summary of the invention

The objective of the invention is the grow wheat two-wire Precision Seeding method of on the basis of " wheat single line Precision Seeding high yield technique ", inventing again, and the sower that is used for this method.

Main method of the present invention is wheat " two-wire Precision Seeding " method.The key of this method is to utilize the Precision Seeding technology, and the single file seeding mode that every sowing of existing wheat is gone changes duplicate rows seeding mode into.When being wheat cultivation, parallel sowing two row wheat seeds in the kind ditch that each plough is left, the spacing of planting ditch is 20-30cm, and the line-spacing of planting seed in the ditch is 3-5cm, and every mu of kind amount is controlled in the 10-20kg scope, and basic seedling is ten thousand of every mu of 10-20.

Seeding method by " two-wire " has suitably increased seeding quantity, both guaranteed " Precision Seeding " requirement, reached rationally " dense planting " again, coordinated the contradiction of growing between wheat individuality and the colony effectively, the fringe that had both reached individual plant is heavy, guarantee the mu spike number again, reached the purpose of super high-yielding.

This invention only need be reequiped sower, under same clay fertilizer water condition, just can obtain to increase production and improve productivity.The peasant is still based on the thick broadcast mode of single line at present.The key technology of this invention is the Precision Seeding dense planting, promotes to get up to be easy to be accepted by the peasant.

It is that it is made up of frame, land wheel, seed-box, seeding unit, grain tube, plough, press wheel, chain gearing that two-wire Precision Seeding machine of the present invention is mainly constructed.It is characterized in that the feed outlet on the seeding unit is the twice of plough number, a grain tube is respectively arranged on each feed outlet; Per two grain tubes are connected in the shovel formula plough simultaneously, two mouths of sowing about the inboard formation of plough, sowing for two separates with " V " type baffle plate between the mouth, two mouthful center distance 3-5cm that sow.Sow the seed that two single lines are arranged like this in each plough simultaneously, promptly reached the purpose of " two-wire Precision Seeding ".

The present invention utilizes the mode of " two-wire Precision Seeding ", go up the realization Precision Seeding at every " single line ", reach dense planting by two " single line " combination, wheat is gone up because of Precision Seeding at " single line " and is grown stalwartness, and wheat population has been given full play to the advantage that reasonable colony achieves higher output because of basic seedling abundance and ontogeny stalwartness.Through experiment utilization the technology of the present invention, adopt the sowing specification of " two-wire spacing 3～5cm, plough line-spacing 23～28cm, basic seedling 12～160,000/mu ", select big fringe compact wheat breed for use, the mu spike number can be controlled in about 350,000, and fringe heavily can be controlled in more than the 2g.Under identical cultivation management condition, " two-wire Precision Seeding " more than 15%, the high-yield field per mu yield can reach more than 650 kilograms than " single line Precision Seeding " and " single line is thick to be broadcast " volume increase.

Embodiment

As shown in Figure 5, seeding method of the present invention is to have broadcast two row seeds in each ditch, two line space a=3-5cm, two ditch spacing b=23-28cm.

As shown in Figure 1 and Figure 2: on frame 1, be fixed with seed-box 8.Land wheel 19 is installed on the support 2 of frame 1 front end by land axle 18, side by side wheel shaft 18 is as power take-off, by chain 4, regulating wheel 3, power is reached in the rotating shaft 7 of precision seeder 6 by movable sprocket 10, power transmission shaft 9, feed outlet on the seeding unit 6 is six, and each feed outlet picks out a flexible pipe.Flexible pipe inserts in the grain tube 21, and grain tube 21 is that internal diameter is the plain cast iron pipe of 20mm.Two grain tubes 21 weld together the leg that constitutes plough 15 side by side, and are fixed on the crossbeam 20, and the spacing b=20-30cm between two legs, the end opening of grain tube 21 are the mouth 23 of sowing, and its end welds together with plough 15.Seed level adjuster 16 usefulness bolts are connected crossbeam 20 and grain tube 21 and plough 15 on the frame 1.Controlled clutch handle 12 can make clutch 17 work, realizes the switching of power, prevents to waste when sower from turning or inoperative is walked seed.Press wheel 14 is fixed in frame 1 rear respectively with handrail 11, and respectively there is a press wheel 14 back of each plough 15, and 11 on press wheel 14 and handrail are connected with copying spring 13 simultaneously.

Plough shape of the present invention as shown in Figure 3, Figure 4, it is to be welded with division board 22 in triangle trench digging 15, the cross section of division board 22 is reverse V-shaped, dehiscing to locate the vertical face of both wings is arc line type, outer wide value a=3-5cm, it can determine the width of two-wire seeding, also can effectively prevent to mix mutually from the seed that two grain tubes 21 fall, they are fallen into respectively in the kind ditch of division board 22 both sides, realize " two-wire " sowing of a ditch two row; Its camber line structure can prevent effectively that weeds obstruction kind of the ditch from influencing sowing depth simultaneously.
