The invention relates to the field of agricultural machinery and relates to an anti-drag subsoiling and intertilling device allowing quick replacement of subsoiling and intertilling shovel points. The device comprises an anti-drag unit (1) and a quick replacement unit (2), wherein the anti-drag unit (1) comprises a first fixed seat (11), a second fixed seat (12), a spring assembly body (13) and a connecting plate (14); the quick replacement unit (2) comprises a shovel shaft (21), a transfer assembly body (22) and the intertilling shovel point (23) or subsoiling shovel point (24); one end of the spring assembly body (13) and the first fixed seat (11) form rotational connection through a hinge pin; the connecting plate (14), the other end of the spring assembly body (13) and the second fixed seat (12) form rotational connection through a hinge pin, and the connecting plate (14) is fixedly connected with the upper part of the shovel shaft (21); the transfer assembly body (22) is fixedly connected to the lower part of the shovel shaft (21); the subsoiling and intertilling shovel points are quickly replaced by the aid of the transfer assembly body (22). The device is time-saving, the machine utilization rate is high, the cultivation drag is decreased, and the power consumption is reduced.

The invention discloses a no-tillage and cold-resistant planting method of winter rapeseed in dry land, which comprises the following steps: in spring, according to the requirements of live-seeding winter rapeseed with no-tillage in the next stubble, fertilization, deep plowing, harrowing, and covering with plastic film are carried out respectively, and spring sows corn in good time The plastic film is not removed during the whole growth period of corn. After the corn is harvested in autumn, the corn stalks are removed, the plastic film is retained, and winter rapeseed is directly planted on the plastic film with no-tillage. As follows: (1) removal of corn stalks; (2) sowing; (3) field management. The method of the invention saves farming time, can realize timely sowing of winter rapeseed, improves soil moisture content and ground temperature when sowing winter rapeseed after harvesting corn, makes seedlings emerge uniformly and grows robustly, reduces procedures and costs.

The invention relates to a pneumatic rape precise combined direct seeder, and belongs to the technical field of seeders. The seeder comprises a frame, a rotary tillage unit, a fertilizer unit, a land-wheel profile device, a sub-frame, a positive / negative air pressure working unit, a positive / negative air pressure combined seed-metering device, a ditching unit and a driven system. The pneumatic rape precise combined direct seeder has the advantages of simple structure, compact layout, low power consumption, little damage on soil, low re-sowing rate and seeding absence rate, and no seed damage,and can realize the combined operation of rotary tillage, stubble cutting, ditching, sowing and fertilization. The pneumatic rape precise sowing can save seeds and greatly reduce the thinning and final singling operation of the later growth management of rape; and the combined operation greatly improves the production efficiency. The seeder is used for precise combined direct seeding of rapeseeds, and also can be used for the precise direct seeding of other small spherical grain-size seeds.

The invention discloses a rice transplanter for simultaneously transplanting male parents and female parents for the seed production of hybrid rice. The rice transplanter consists of a transplanting mechanism, a box moving mechanism, a longitudinal rice seedling conveying mechanism, a rice seedling box, a rice seedling boat, a tail plate and a power drive device; the transplanting mechanism comprises 12 rice seedling transplanting arms, including 10 female parent rice seedling transplanting arms and 2 male parent rice seedling transplanting arms; the female parent rice seedling transplanting arms are distributed on the two sides, and the space between adjacent female parent rice seedling transplanting arms is 177 mm; the space on one sides of the male parent rice seedling transplanting arms is 238 mm, the space on the other sides of the male parent rice seedling transplanting arms is 300 mm, the space between two male parent rice seedling transplanting arms is 291 mm; each time of transverse movement distance of the rice seedling box is 20 mm; each time of rice seedling conveying distance of the longitudinal rice seedling conveying mechanism is 18 mm; the transplanting work of male parent rice seedlings and female parent rice seedlings is finished by simultaneously transmitting power to the male parent rice seedling transplanting arms and the female parent rice seedling transplanting arms and simultaneously conveying the rice seedlings in the transverse direction and the longitudinal direction via the power drive device. By adopting the rice transplanter, labor intensity can be reduced greatly, rice transplanting efficiency can be improved, farming season can be saved, production cost can be reduced, and the problems of labor shortage, unstable seed quality and the like are solved.

The invention provides a herbicide composition. Active ingredients in the composition comprise dicamba and clodinafop-propargyl in a ratio of (1:1)-(40:1). The herbicide composition can be prepared into wettable powder and water-dispersible granules according to the known methods. The herbicide composition has the following advantages: relative to the single agent, on the premise of expanding the weed-controlling spectrum, the herbicide composition delays generation of weed resistance, improves the pesticide effect, has low residues, is safe to wheat and afterreap crops and can control most monocotyledon and dicotyledon weeds in wheat fields once. The invention also provides application of the herbicide composition in controlling weeds in the wheat fields.

The invention relates to a driving disc corn ridge culture no-till seeding machine, and belongs to the technical field of agricultural machinery. The machine comprises a transmission device mounted ona box type mechanism, a driving disc rootstalk breaking mechanism, a ridge fixing mechanism, an anti-grass-hanging mechanism, a seeding device, a fertilizing device and a soil scraping cleaning mechanism. The machine can simultaneously complete multiple processes such as furrowing and ridging, rootstalk breaking on ridges, fertilization, seeding, and suppressing, so that labor intensity is reduced, working efficiency is improved, and high-quality and high-efficiency integrated operation is effectively realized; and the operation quality is good, the efficiency is high, the operation is reliable, and the universalization degree is high, therefore, the machine fully satisfies the agronomic requirements of agricultural product cultivation industry.
