The main differences between powder,premixed agent, granule are as follows:
Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing.
Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation.
As a dosage form of feed drug additive, it is specially used for mixed feeding.
Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows:
1.the production method is different
1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation.
2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate.
3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation.
2.different characteristics
1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take.
2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed.
3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.

Huayu 25 Peanut-covered High-yield Cultivation Techniques
**Huayu 25 Peanut High-Yield Cultivation Techniques**
*Source: Seed World*
Zhang Qiu and Zhao Guoxia (Agricultural Technology Promotion Center, Lianshan District, Huludao City, Liaoning Province)
Huayu 25 is a large-seeded common variety with a growth period of about 148 days. It is considered a late-maturing type. The plant has yellow butterfly-like inflorescences, with a compact growth habit, standing upright, and an average height of 52 cm. It has 9–10 branches, short and narrow in angle, resulting in concentrated pod development and good uniformity. The pods are 3.7 cm long, with an average weight of 206.3 g per pod. One thousand seeds weigh approximately 485 g. In film-mulched cultivation, there were 16 single-cultivated plants per plot, with 10.8 pairs of diploid plants, accounting for 65.8% of the total. There were 0.44 shriveled pods, making up 2.68% of the total. Each plant produced an effective weight of 32.99 g. The shells are thin, with small cavities, and the out-of-rice rate reaches up to 76.48%. The grains are large, full, pink, and smooth, with 100 seeds weighing 95.17 g. The yield of pods is 7,974 kg/ha, and the seed kernel yield is 6,055 kg/ha. This variety exhibits strong resistance to wind, drought, lodging, and leaf diseases.

**1. Site Selection**
Choose fields with good water supply, flat terrain, deep soil, and loam or sandy loam texture. Avoid areas that have been previously planted with legumes. It is best to follow crops like corn, sorghum, or millet.
**2. Field Preparation and Furrow Making**
Prepare the soil in spring, creating furrows 55–60 cm wide and 10–15 cm high. Apply base fertilizer in the middle of the furrow, digging a ditch 10–15 cm deep. Use 375 kg/ha of compound fertilizer, and plant seeds 30–40 cm apart on both sides of the ditch.
**3. Determine Sowing Time**
This variety requires 145–148 days to mature, so it can be sown early. In the Huludao region, planting should begin when the temperature stabilizes above 15°C, typically between May 1st and May 5th, with the latest date being May 10th.
**4. Ensure Seeding Rate and Quality**
4.1 **Seed Reserve**: To achieve high yields, maintain at least 270,000 plants per hectare, with a maximum of 2.85 million. Ensure each plant produces at least 360 kg of pods.
4.2 **Seed Selection**: Remove discolored, damaged, or cracked seeds. Separate large and small seeds for better uniformity.
4.3 **Pre-Sowing Treatment**: Treat seeds with pesticides like carbendazim and ammonium molybdate. Soak them in water and inoculate before drying in a cool place. Mix 50% phoxim (1125 mL/ha) with water and grind with 60 kg/ha of corn stalks to create poisoned soil, which is applied in the furrow first.
4.4 **Seeding**: Depending on soil moisture, sow 2 seeds per hole, spaced 14 cm apart, with 30–40 cm between rows. Cover the seeds with 2–3 cm of soil, then apply a special peanut herbicide. Avoid using grass-specific herbicides; common options include acetochlor and chloriminate. Ensure the plastic film is well-pressed, with spacing of 3–5 meters between rolls.
**5. Ventilate Seedlings and Promote Growth**
After emergence, gradually release the seedlings from the film. Start by opening the small eyes, then the larger ones, and finally remove the film completely. During hardening, avoid removing the film all at once. Only allow the first pair of lateral branches to emerge. Keep the film in place to prevent wind from lifting it.
**6. Pest Control**
Common pests include aphids, red spiders, and cotton bollworms. Aphids are the most dangerous. Early detection and timely treatment are essential for effective control.
**7. Fertilization and Irrigation**
During flowering, early fruiting, and full fruit stages, provide sufficient water if dry. During the ripening stage, apply foliar fertilizer every 7 days for three consecutive times. This helps improve photosynthesis, increase grain filling, and enhance yield.
**8. Timely Harvesting**
Harvest when the lower leaves turn yellow and the inner walls of the pods turn brown. Alternatively, consider the variety's growth duration and weather conditions to make a balanced decision.
