First, seed treatment
Promoting seed coating with seed coating agents to prevent plant diseases and insect pests. Seeds that are not coated with a seed coating agent are seed dressing. In the case of a heavier root disease, 2% tebuconazole (Liquefone) was used. The seed amount was 0.1% to 0.15%, or 20% triadimefon (triadimefon) was 0 per seed amount. 15% of the seed dressings; where heavy pests occur in the ground pests, 40% methylisosalt-phosphate or 35% methylthiophosphorus EC is used, and 0.2% of seeds are seeded; disease and insects are mixed. The plots were mixed with the above fungicides + insecticides.
Second, the fine soil preparation
In accordance with the requirements that the straw must be deep-cultivated and rotary-cultivated sowing must be compacted, the quality of soil preparation should be improved, the foundation for wheat sowing should be strengthened, and the ability to resist disasters should be strengthened. Expand the area of ​​mechanical deep plowing (deeply loosening) and do a good job of uniform deployment of large and medium-sized agricultural machinery. After the autumn crops are harvested, we should intensively carry out mechanical tillage with a plow depth of 23 cm or more. After plowing, plow up and suppress 2-3 times as quickly as possible to break up. Soil smashing, smashing soil blocks, loosening the topsoil, leveling the ground, applying Panasonic to reduce evaporation, and resisting drought and defoliating soils; Rotating arable blocks should be turned twice, with a cultivating depth of 15 cm, and tamped after ploughing; rotary cultivating for 3 consecutive years Plots should be combined with corn stalks to implement deep ploughing (deep slashing), breaking the plough bottom layer, loosening the soil, improving soil physical and chemical properties, increasing soil supply and coordination of water, fertilizer, gas, and heat, and enhancing wheat's resistance to stress.
Wheat field cultivation, so that the fine soil preparation, ensure that the same depth and sowing, watering evenly, save water. Pouring good conditions for water pouring should be as large as possible. Poor conditions for water pouring can be used for small crucibles.
Third, enough to reproduce
"Weak late sowing, sowing early, timely planting wheat seedlings." The following is the key to ensure the seedlings are full, Miao Qi, Miao Zhuang, "Mill's income every other year" is to emphasize the importance of the bottom. Astragalus seeding or lack of oral hygiene, slow emergence but not homogeneous, delayed delivery, lack of delivery, thin seedlings weak. Therefore, we must do enough. Insufficient should be poured at the end of drowning, but also to protect the mouth to ensure that the whole seedlings broadcast. For land masses with poor soil quality, poor cultivable properties, and hard-to-preserve soil, they can also be planted first, followed by sprinkling or pouring head water. However, it is planned that the land to be poured into the headwaters should be sown. After the ground is dry, it should be removed in time and the compaction should be removed to facilitate the emergence of seedlings.
The suitable broadcast period in Liaocheng is from October 3 to October 12. The best sowing date is from October 5 to October 10. During the suitable sowing period, we should master the principle of preferring late planting and also planting plantar pods so that sufficient planting can be achieved and the dry land must be planted so as to ensure full seedlings are broadcast. Since corn plentiful in this year may be relatively concentrated, corn harvesting and wheat planting machinery must be prepared as soon as possible in various regions to speed up machine harvesting and planting schedules to ensure that wheat can be sown within a suitable period. For wheat that cannot be sown within the appropriate period, it is necessary to pay attention to increasing the sowing amount appropriately so that the sowing time can be combined.
In recent years, the sowing amount of farmers in many areas has increased significantly, and there are huge hidden dangers of prosperous growth and lodging, which is very detrimental to the high and stable production of wheat. Therefore, in the autumn of this year, it is necessary to vigorously promote semi-finishing of fine-seeding and firmly suppress the phenomenon of large-scale broadcast.
IV. Seedling replanting
After sowing wheat, due to various reasons often caused by lack of seedlings broken ridge, therefore, after the emergence of wheat, it is timely to check the emergence of seedlings in the field, generally according to "three inches without seedlings for lack of seedlings, five inches without seedlings for broken ridge," Remedy the lack of seedlings and ridges. There are two methods: one is seedling reseeding, and the other is seedling transplanting. Check seedlings should be filled in the 1-2 leaf period. Select the seeds of the same species as the plot and apply seed coating or seed dressing. Spread the seeds evenly and dilute the seeds. Poor waterlogging should be combined with watering. The transplanting of seedlings in thinning is done on the land after the three-leaf period has not been replanted in time. After transplanting, the seedlings are transplanted and transplanted sparsely, sparsely in situ, and sparsely planted. In order to ensure survival, it is appropriate to cover the depth of soil with "no pressure and no whiteness."
