The invention discloses a method for high-yield cultivation of hybrid millet of coastal moderate and severe saline and alkaline land. The method comprises the following steps of: (A), performing saline-alkali-resistant pelleting treatment on millet seeds, namely wrapping a layer of saline-alkali-resistant pelleting agent on the surfaces of the millet seeds to form pelleted seeds with the diameters of 2 to 5mm; (B), performing post-rain shallow seeding, namely performing precision drilling by using seeding machinery when the single rainfall capacity is over 50mm; (C), performing chemical weeding, namely adding 20 to 25kg of water into 100ml of herbicide and 10mg of anti-lodging agent and uniformly spraying on each mu of land at a 3-5 leaf stage of millet; and (D), applying a small amount of fertilizers for multiple times, namely applying 5 to 10kg of diammonium phosphate serving as seed fertilizer to each mu of land, additionally applying 5 to 7.5kg of urea and 7.5 to 10kg of diammonium phosphate to each mu of land at an elongation stage, and additionally applying 15 to 20kg of urea and 5 to 10kg of potassium sulfate to each mu of land at a heading stage. The high-yield cultivationof the hybrid millet in coastal saline and alkaline land is realized by comprehensively applying technologies such as a saline-alkali-resistant pelleting technology, a post-rain shallow seeding technology, a precision drilling technology, a chemical weeding technology and multiple application of a small amount of fertilizers.

The invention relates to an agricultural machine, in particular to a vibrating grass-cutting slotted machine which is used by matching with a tractor. The invention aims at providing the vibrating grass-cutting slotted machine, which can reduce the plowing resistance under the action of a vibrating system and can shut the slot under the action of a soil-rolling system, thus facilitating the vibrating grass-cutting slotted machine to expand the operational span for protecting the slot. The vibrating grass-cutting slotted machine comprises a gearbox (1) and a stander(3), and is characterized in that a cutting system which comprises a cutting disc (5) is fixed on a falsework (7); the vibrating system comprises a crank connecting rod component (2) fixed on the stander (3); the front end of the falsework (7) is fixed on the front end of the stander (3) by an axis pin (3), and the rear end of the falsework (7) is connected with the crank connecting rod component (2); the gearbox(1) is connected with the vibrating system for distributing power; a soil-rolling adjusting system comprises a supporting wheel (9) fixed on the stander (3) and a soil-rolling wheel (4).

The invention relates to a seedling planting, fertilizing, ridging and compacting integrated machine, and belongs to the field of seedling planting equipment. The seedling planting, fertilizing, ridging and compacting integrated machine is characterized in that a walking driving mechanism (9), a spacing setting mechanism (10), ridging mechanisms (11) and a compacting mechanism (7), wherein a driving walking wheel (901) of the walking driving mechanism (9) is connected with the spacing setting mechanism (10) through a transmission mechanism, the ridging mechanisms (11) are symmetrically arranged at the two sides of the spacing setting mechanism (10), and a water and fertilizer adding mechanism (3) is rotationally connected to one side of the spacing setting mechanism (10). The whole planting processes of seedling planting, watering and fertilizer applying, soil covering and compacting of fruit seedlings can be continuously completed at a time, water and fertilizer can be synchronously applied after planting, and it is thoroughly avoided that in an orchard with low soil water content, the fruit seedling survival rate is affected when water and fertilizer cannot be applied in time during fruit seedling planting.

An agricultural ridging machine comprises a soil-pressing plate. The soil-pressing plate is provided with a top end soil-pressing plate; the two sides of the top end soil-pressing plate is connected with two side soil-collecting plates by a connecting piece; the front end of the top end soil-pressing plate and the front end of the two side soil-collecting plates are provided with outward openings; the section of the soil-pressing plate is trapezoid; a mounting leg is connected to the top end pressure soil plank; a vertical post of the mounting leg is connected with the vertical part of the connecting pipe by a screw; and the horizontal part of the connecting pipe is provided with a traction connecting hole. The agricultural ridging machine has the advantages that: two side soil-collecting plates and the top end soil-pressing plate are used for extruding and compacting the soil, so that the ridged soft soil is in a flat ridged platform form, and the cross section is trapezoid; the ridged platform with stable shape and compactness is convenient for subsequent planting, laminating and conversing soil moisture.

The invention belongs to the technical field of agricultural machinery and particularly relates to a seed furrow clod breaking roller. The middle of a bolt III is movably connected with two through holes of a clod breaking rolling arm. The two ends of the bolt III are fixedly connected with two through holes of a connecting frame. Two spring coils of a parallel double-torsion spring are movably connected with the middle of the bolt III, a middle torsion arm of the parallel double-torsion spring is limited by a groove of the clod breaking rolling arm, and two side torsion arms of the parallel double-torsion spring are limited by two grooves of the connecting frame. The two ends of one bolt are fixedly connected with a flat plate and the connecting frame, and the two ends of the other bolt are fixedly connected with the flat plate and the connecting frame. The upper outline of the clod breaking rolling arm is composed of an arc AH and an arc GH. The outline of the bottom surface of the clod breaking rolling arm is composed of a straight line AB, a curve BF and an arc FG, the curve BF is a part of a logarithmic spiral, the clod breaking rolling arm is provided with a hinge region, a transition region, a clod breaking region and a rolling region, and clod breaking teeth are arranged at the bottom of the clod breaking region. The soil contact component of the seed furrow clod breaking roller is free of soil adhesion, resistant to abrasion and long in service life, and the working effect and stability can be improved. When the seed furrow clod breaking roller is used in cooperation with a rolling wheel, seed covering quality and sowing depth consistency are high, and the yield of crops can be increased.

The invention discloses a technology for controlling and eliminating weeds in an alfalfa field by film-side planting. According to the technology, the coverage of the weeds in the alfalfa field can be effectively controlled, and can be reduced by 21 to 46 percent; in addition, the annual yield of alfalfa hay is greatly increased by 19.8 to 152.6 percent; total yield per hectare in three years is increased by 9,387.6 to 9,438.4kg, and if per ton of alfalfa hay is 2,400, economic benefits per hectare can be increased by 22,530 to 22,652 yuan, and efficiency per hectare is equivalently improved by 1,502 to 1,510 yuan; moreover, the using amount of a weed killer is reduced, pollution to the environment is reduced, and the target of low-environmental consumption production of the alfalfa industry can be effectively promoted.
