First, the fine soil preparation before the cultivation of land is mainly to immediately exterminate, as far as possible to save precipitation during the rainy season, while the uneven ground before the ploughing to increase the filling and increase the flatness. After the cultivation, the soil preparation is mainly to further crush the soil and increase the tightness of the topsoil and the leveling of the ground. Before and after the snoring, the soil can be set as required. For deep, high-yield fields with deep soil, the depth of ploughing should be 25 cm or more, and the middle tract should be 23 cm or more. In general, the machine cultivation should be combined with the machine and the soil preparation should meet the following agronomic requirements: timely, in order to facilitate drought protection; the topsoil layer is loose and loose, and there is a certain degree of tightness under the topsoil; the working depth must meet the specified requirements and maintain the same depth. Flat ground, no leakage, leakage pressure phenomenon. Commonly used soil preparation machines are disk rakes, nail rakes, and rotary cultivators. On the basis of a good land, we must make good efforts to ensure that we plant enough seeds. In dryland wheat fields, when the rain meets, the seeds must be sown to ensure the seedlings are full and Miao Qi.
Second, the selection of improved varieties of rational use of improved varieties is a simple and easy increase in production measures. However, thoroughbreds are relative. Each breed has its own characteristics, all require certain cultivation conditions and production levels, reasonable selection of good varieties of the road, and do a good job in variety layout. However, the selected species should not be too much or too little. Too much variety can cause seeds to be mixed, and too few can reduce the overall resilience. In the selection of varieties, special attention should be paid to the following points: First, use medium-early-maturing varieties as much as possible so as to avoid natural disasters such as dry hot wind, and facilitate the timely harvesting and growth of the crops under the crop. The second is the selection of varieties with a longer suitable sowing period and a more flexible sowing date. The third is to select varieties with strong lodging resistance, and to support the promotion of semi-finished sowing techniques for precision sowing, establish a reasonable group structure, reduce pest damage, and reduce the danger of later lodging.
Third, the use of seed treatment agent treatment, can effectively control wheat sheath blight and underground pests, etc., and can also treat rodents.
Fourth, formula fertilization In addition to early arable land and irrigated land to vigorously promote the return of straw, but also wide open source of fertilizer, increase organic fertilizer, fertility and fertility, wheat is the basis for achieving high yield and quality. We must pay attention to the rational use of chemical fertilizers, and focus on adjusting the ratio of nitrogen and phosphorus in order to improve fertilizer efficiency. High-yielding fields need to “control nitrogen, increase phosphorus, and increase potassiumâ€, and high-yield fields should “stabilize nitrogen and increase phosphorusâ€, and low-yield fields should “increase nitrogen and increase phosphorusâ€. High-yielding fields generally apply 50-70 kg of standard nitrogen fertilizer per 667 square meters, 40-50 kg of standard phosphate fertilizer, 10 kg of potassium fertilizer, 1.5 kg of zinc fertilizer, and all base fertilizers of organic fertilizer, phosphate fertilizer, and potassium fertilizer, and 50% of nitrogen fertilizer. , 50% jointing stage topdressing; middle production field generally applies 50-60 kg of standard nitrogen fertilizer per 667 square meters, 50 kg of standard phosphate fertilizer, 5-10 kg of potassium fertilizer; low-yield field applies 40-50 kg of standard nitrogen fertilizer per 667 square meters. Phosphorus fertilizer 50 kg. At the same time pay attention to fertilization methods to improve fertilizer efficiency. Ammonium bicarbonate should be applied to the plow so as not to volatilize the fertilizer and reduce the fertilizer effect.
V. Proper sowing at appropriate dates is also an important measure to ensure the completeness of wheat seedlings and seedlings. Therefore, we must strictly control the sowing time and ensure proper sowing.
Sixth, suitable for deep sowing In deep plowing, the wheat roots are mainly distributed in 0-50 cm soil layer, and under shallow tillage and rough soil, they are distributed in 0-20 cm soil layer. many. The sowing depth of wheat is preferably 3-4 cm. When sowing is too deep, the stems in the wheat field are elongated for too long, so that the normally-not-stretched tiller section is stretched from the first to the second internodes. In the process of seedling emergence, too much nutrients are consumed in the seeds, and the growth of the seedlings is weak. Less, the accumulation of nutrients within the plant is small, the ability of resistance to freezing is weak, and large numbers of dead seedlings are easily planted in winter and early spring. When the seed is too shallow, the seeds will dry out due to soil loss during sprouting and emergence of seedlings. Shallow childbirth is too close to the ground and weak antifreeze is not conducive to safe wintering.
7. The planting period of pests and weeds is the key period for preventing various kinds of wheat diseases and pests, weeds and rodents in wheat fields. It is necessary to adhere to the plant protection policy of “prevention-oriented, comprehensive prevention and controlâ€, and effectively implement pesticide seed dressing, soil treatment and seed packages. Clothing work, and strive to fully control the hazards of wheat field pests, to ensure the safe production of wheat.
Eight, re-grasping techniques such as dry farming must choose drought-resistant wheat varieties, in order to plant provincial water; and to do fine soil preparation, apply more organic fertilizer and increase phosphate fertilizer, in order to play a role in water storage, water conservation and fertilizer Ji Shui . Dry wheat crops should be sown early in time and a reasonable population should be established to save water. In addition, the timely eradication, scratching, and repression are also important measures for increasing wheat yield in dryland.
The treatment of seeds, to a certain extent, is to increase the germination rate of seeds, and to increase the germination rate of seeds. Incubators can be used. It is recommended to use an artificial climate incubator, which can be used to germinate other seeds, and can appropriately increase the germination rate of seeds. .
Application of excavator hydraulic cylinder:
The hydraulic cylinder of an excavator is an important component, mainly used to control the movement of the excavator's mechanical arm, stick, bucket head, and other parts. Specific application scenarios include:
1. Construction engineering: Excavator hydraulic cylinders can be used for excavation and transportation of earthwork, excavation of foundation pits, road construction, pipeline laying, and other construction projects.
2. Mining: Excavator hydraulic cylinders can be used for ore mining, blasting, transportation, and loading in mining.
3. Agricultural production: excavator hydraulic cylinder can be used for Land consolidation, irrigation and drainage, ditch excavation, crop harvesting and other work in agricultural production.
4. Hydraulic engineering: Excavator hydraulic cylinders can be used for river dredging, embankment construction, reservoir construction, and other work in hydraulic engineering.
5. Garbage treatment: The excavator hydraulic cylinder can be used for garbage cleaning, compression, transportation, and landfill in garbage treatment.
In summary, excavator hydraulic cylinders are widely used in various engineering and production fields, and are important tools for improving work efficiency and production efficiency.
