How to Achieve a Preserved Seedling in Longdong Wheat District
Winter wheat is the main food crop in Longdong area. To ensure that the number of mu spikes depends on one seeding and preservation of seedlings, and to achieve Miao Qi, uniform seedlings, and strong seedlings, we must work hard on the word “speciesâ€. After years of trials and production practices, the following key technologies have been summarized in production:
1. Return straw, apply organic fertilizer, improve soil, and fertilize fertility.
2. Apply base fertilizer. High-yield fields need to control nitrogen, phosphorus, potassium, and micro-doses; in the middle-quality fields, it is necessary to stabilize nitrogen and phosphorus, make up potassium, and match micro-amounts; in low-yield fields, nitrogen and phosphorus are added, and base fertilizers are added.
3. The next one is enough. If there is no big rainfall before sowing, there is a lack of public opinion. The late-mature plots of corn promoted pre-harvest corn cropping and played a dual-purpose role in ensuring that the wheat was adequately planted at the right time.
4. Fine soil preparation. The root system of wheat is relatively developed, 70% of which are concentrated in the plough layer 10-30 cm above the surface, and fine soil preparation before sowing has important significance for promoting the development of the wheat root system and achieving high yield.
5. Chemical seed dressing. Do select seeds, germination test, seed drying, seed dressing or seed coating.
6. timely sowing. The suitable sowing date for winter wheat in eastern Fujian is from September 27 to October 6, and the best sowing date is from September 27 to October 3.
7. Appropriate sowing. During the suitable sowing period, the basic seedlings of the mu are generally controlled at 230,000-280000, and the sowing rate of mu is 12-14 kg. Plants with high soil fertility, early sowing, high seed germination rate, low grain weight, strong tillering ability, and high rate of spike formation should appropriately reduce the seeding rate, and vice versa; the sowing amount should be increased in late planting, and 0.5 kg per day per mu should be increased. To ensure sufficient acres of mu.
8. Waiting for planting in order to make full use of land, improve community structure, and facilitate field operations.
9. Suitable for broadcast depth. When sowing, it is necessary to adjust the seeder so that it can be evenly distributed and evenly walked, so that the seeds can be evenly distributed, the rebroadcasting is not repeated, the sowing depth is appropriate, and the depth is consistent.
10. Crack down. For the straw returning field and the deep pine plots, repression should be carried out before sowing.
