The modern wheat production management process is simplified, and the focus is on grasping the seeding links, laying the foundation for the seedlings' full seedlings and vital for capturing the harvest of wheat. The standardized wheat sowing technology is based on local conditions, scientific and orderly, efficient and finely implemented series of technical measures such as replenishing hoeing, cultivating soil preparation, seed treatment, appropriate sowing, and suppression after sowing to ensure the operation quality.

The standardized seeding technology of wheat has gained high yield and high efficiency by cultivating pre-winter seedlings and improving wheat's ability to resist cold and drought. Its technical points:

1. Improve the quality of land preparation. The purpose of cultivation and soil preparation is to make the wheat field reach deep plowed layer, coordinate the water, fertilizer, gas and heat in the soil, moderate soil tightness, and have strong water retention and fertilizer retention, and the ground level is in a good condition. It is in line with the wheat sowing requirement and is full seedling and strong. Seedlings and plants grow well to create conditions. China's climatic conditions are complex, there are many kinds of soil, and the planting system is diverse. Therefore, there are many kinds of soil preparation technology before the sowing of wheat fields, and local governments can select suitable cultivation and soil preparation technologies because of conditions. The general principle is based on ploughing (cultivation) or less no-tillage (rotary tillage) based on the combination of hoeing, hoeing, pressing, ridging, ditching, rakes, etc., to properly grasp the appropriate ploughing and hoeing. The timing of such operations will reduce the cost of farming and energy consumption, so that reasonable farming practices can be ensured.

2. Choose good breeds. During the production, the most suitable varieties should be selected based on the climate, soil, soil strength, cropping system, yield level, and pest and disease conditions of the area. (1) Winter, semi-winter or spring varieties are selected based on the climatic conditions in the area, especially the temperature conditions. (2) Choose good seeds according to the production level. For example, dry and thin soils should be selected for drought-resistant and drought-tolerant varieties; in dry soils with thick soil layers and high fertility, drought-resistant and fertilizer-resistant varieties should be planted; and in high-yielding fields with good fertilizer and water conditions, fertilizers with high yield potential should be used. , Anti-fall varieties. (3) According to different farming systems, select good varieties. Such as wheat and cotton intercropping, not only requires that wheat varieties have the characteristics of suitable late sowing and early maturing, in order to shorten the symbiotic period of wheat and cotton, but also require the characteristics of shorter plants, compact plant type, and strong advantages of edge lines to fully utilize light energy. Improve photosynthetic efficiency. (4) According to the characteristics of local natural disasters, select good varieties. (5) Grain quality and good commercial property. Including nutritional quality, processing quality meets the requirements of finished products, full grain, high bulk density, and high sales price. (6) Selection of improved varieties should be tested and demonstrated. In terms of production, we must constantly change new varieties based on changes in production conditions and yields, and also prevent the introduction of large numbers of varieties and frequent replacement of improved varieties without trials; while planting local major promotion of improved varieties, we must pay attention to actively introducing new ones. Varieties are tested, demonstrated, and seed-breeding work done in order to identify "successful" varieties and maintain the high quality of production. The selected varieties are seeded or seeded before sowing.

3. Suitable for sowing. Appropriate soil moisture in the plough layer when wheat is sown is relative soil moisture of 75%-80%. Sowing under conditions suitable for lyrical conditions can ensure that the whole seedlings are once seeded, the seed roots and the secondary roots grow out in time, and they are tied down to deep soil to improve the ability to fight drought. Therefore, when the sensation is insufficient before planting wheat, watering should be done in advance.

4. Suitable sowing. The proper sowing of wheat can make full use of caloric resources, nurturing strong seedlings, forming robust large branches and well-developed root systems, manufacturing and accumulating more nutrients, enhancing resilience, and laying the foundation for raising the spike rate and cultivating strong stalks and spikes. . This is an important measure for the balanced production of large areas of wheat. The sowing date of wheat differs significantly depending on the climatic conditions, production conditions, and species characteristics of different regions. Our country has a vast area and there are great differences in the appropriate timing of winter wheat planting in various regions.

5. Appropriate sowing. At present, various kinds of winter wheat fields in China have the problem of too large seeding volume, resulting in large groups, prosperous winter and spring, thin stalks, easy lodging, ear and ear small, easy to premature aging, the output is not Higher issues. To determine a reasonable amount of sowing can obtain the appropriate number of basic seedlings, establish a reasonable group structure, deal with the conflicts between groups and individuals, and it is an important link to coordinate the relationship between wheat growth and environmental conditions. Master the principle: First, the characteristics of the species. Mainly refers to the tillering power, the tillering rate of spikes and the number of appropriate mu spikes; the second is the sowing date sooner or later; the third is the soil fertility level. Generally, the seedlings with strong tillering ability and high spike-forming rate, early sowing date and higher soil fertility should be diluted with basic seedlings, and the seeding amount should be less.

6. Seed dressing before sowing. Before sowing, soak in the new high-fat membrane, remove, and dry. Can keep warm, moisturize, absorb, increase seed germination rate, make seedlings robust. Repel underground pests and isolate virus infections. Can also be mixed with seed coating agents.
