1 Arable land operation

1.1 For some lands with poor land surface smoothness, work grounds shall be taken after the stems are returned to the field and flat or plowed.

1.2 The plowing machinery is installed with the auxiliary plough, which can effectively cover the cotton stalk and reduce the workload of the Qingtian. The distance between the secondary plough and the main plough tip is 30-35 centimeters in height, and the height of the secondary plough should be 10-12 centimeters deep, effectively covering the weeds and straw.

1.3 Stem crushing The height of the clams is controlled at 8-10 cm, and the crushing length of the cotton swab must not be greater than 10 cm.

1.4 The plots that are to be planted with cotton and tomato sauce must all be subject to basic chemical fertilizer application, while at the same time increasing the area of ​​basic application of grain and other crops. In the whole growth period of cotton and tomato, the fertilization rate of mu exceeds 150 standard fertilizers, the ratio of nitrogen to phosphorous is 1:0.4, 50% of phosphate fertilizer is applied, and the whole layer of precision fertilizer is 15 kg of diammonium per acre or 30 kg of organic compound fertilizer. Diamine 5 kg, spread fertilizer evenly with a precision manure spreader.

1.5 Quality requirements. Timely tillage, depth requirements to reach 26-28 cm, the same depth, the error does not exceed 5%; bracts flip well, the surface is smooth, there is no immediate return, the ground cover, weeds and fertilizer coverage reached more than 90% Requires consistent tillage and ups and downs, 50 meters straightness error not exceeding 15 centimeters, neat land, no re-cultivation, no ploughing, no tillage, arable land from head to edge, edge line, angle into square; plowing land and straw buried in soil Below 12 cm in the surface layer, the residual rate of surface straw in the field does not exceed 5%. The operation of opening and closing ridges is alternated, and it is not allowed to repeat one kind of tilling direction for many years. The operation of opening and closing ridges strictly follows the technical requirements and eliminates the occurrence of ridge tables and ridges.

2 Site preparation

2.1 In a timely manner, coordinate the efforts to carry out site preparation operations for the plowed land, and effectively achieve the requirements for land preparation in Panasonic.

2.2 The depth of soil preparation is determined according to the public opinion. Generally, it is 8-10 cm deep and 12-15 cm deep. The pass rate is greater than 80%.

2.3 Site Preparation Quality. The emphasis is on "Qi and Ping", and strict implementation of the short-spot land preparation method. Site preparation operations must be carried out to the end, to the side, not missing the entire surface; there is no obvious phenomenon of ditch, ridge and high package on the surface.

3 Autumn fall and site preparation work should pay attention to safety and avoid mechanical accidents and personal injury accidents.

3.1 The locomotives and operators participating in the operation must have the license of the licensee, pass the annual inspection and pass the inspection, and participate in insurance. Establish safety awareness and prevent accidents.

3.2 Pay attention to safety during operation. When connecting agricultural implements, low-speed and small-throttle reversing should be taken. Pay attention to the safety of the personnel engaged and prepare the brakes at any time. For the traction and attachment of the implements, the prescribed safety pins and the standard locking devices shall be used; the operators in the operation shall pay attention. Concentration: When the tractor starts to stop, it needs to send a signal to ensure safety before starting. It is necessary to adjust, troubleshoot, or remove the weeds during the operation. The soil must be parked; the plough can not be turned and retreated after entering the soil; the farm is strictly prohibited from carrying people; The lights must be complete and effective, with concentrated energy. It is forbidden for personnel to rest in the fields.

4 Farm Machinery Maintenance

4.1 Maintenance of tractors. After the repair, the tractor must achieve “five nets, four leaks”, namely: “Gas net, oil net, water net, body net, tool net; no leakage, no leakage, no leakage, no leakage” engine horsepower recovery To more than 95% of the rated horsepower, and the locomotive unified standard spray paint.

4.2 Repair of agricultural implements. Serious and thorough cleaning of farm tools to be repaired, leaving no dead ends. After the repair of farm tools, it must achieve the technical status of “six in, three inflexible, and one in good condition”, namely: “no defect, no deformation, no corrosion, no shaking, no looseness, no shortage of oil; flexible rotation, flexible transmission, and flexible operation; The state of the technology is intact." And placed neatly, lift up the isolation floor, centralized parking, paint rust. After repairs, the farm implements eliminated the presence of non-standard parts, eliminated painting on the surface of working parts, and prevented the application of waste (chai) oil on the surface of the parts. Equipped with a full complement of small agricultural implements (耱, tampon, small nails, hedgehog rolls, etc.).
