Peanut Flowering and Pegging Stage High-Yield Management Techniques
The flowering and pegging stage of peanuts is a critical period for peg formation and pod development, requiring comprehensive management practices. Let's explore the techniques for high-yield management during the flowering and pegging stage of peanuts.
1. Controlling Excessive Growth
During the flowering and pegging stage, which typically occurs from late June to early July, the soil temperature is high, and the application of base and topdressing fertilizers promotes vigorous plant growth, leading to rapid stem elongation and leaf expansion. Therefore, it is essential to control excessive growth. When the peanuts reach a height of 30-35cm or during the late flowering stage and early pod formation, apply 50% propiconazole at 50g per acre or 250g/L imidacloprid at 20ml per acre.
2. Nutrient Supplementation
After controlling excessive growth, supplementing with potassium dihydrogen phosphate can increase plant nutrition, promote flowering, and fruit setting. Alternatively, foliar spray with 170g/L liquid calcium fertilizer at 20ml per acre along with 10% liquid boron fertilizer at 10-15g per acre can be applied.
3. Disease Prevention and Control
Peanuts are susceptible to various diseases such as leaf spot and wilt, but during the flowering and pegging stage, it is crucial to prevent white mold. White mold often occurs during the later stages (July-August) in hot weather, affecting the stems, peduncles, pods, and roots of peanuts, leading to severe yield reduction. It is recommended to spray 25% azoxystrobin at 15-20ml per acre mixed with 30% tebuconazole suspension at 20g per acre diluted in 60kg of water.
4. Pest Prevention and Control
During the flowering and pegging stage of peanuts, attention should be paid to the prevention and control of aphids. Aphids primarily damage flower stems, pegs, and branches in dry conditions. Failure to prevent aphids in advance can lead to widespread damage, including the secretion of oily mucilage on affected plant stems and leaves, resulting in flower and peg withering, branch aging, and leaf wilting. Additionally, cotton bollworms should be monitored, especially in warm and humid conditions, as they thrive during this period and can damage peanut leaves, flowers, and pods. Use fungicides and insecticides such as carbendazim, imidacloprid, and cypermethrin to control peanut pests.
Conclusion
These are the techniques for high-yield management during the flowering and pegging stage of peanuts. By implementing these management practices effectively, peanut growers can achieve high yields and quality. It is essential for farmers to pay attention to these aspects.
Frequently Asked Questions (FAQs)
1. What is the germination time for Solomon's Seal seeds?
The germination time for Solomon's Seal seeds is relatively long, typically taking about 12 months from sowing to seedling emergence, and another 12 months for the seedlings to grow into robust plants.
2. How can I collect Solomon's Seal seeds?
To collect Solomon's Seal seeds, choose seeds from healthy mother plants with full fruits. Harvest the seeds when the berries turn from green to yellow or black.
3. How can I break the dormancy of Solomon's Seal seeds?
The dormancy of Solomon's Seal seeds can be broken by soaking them in a 300-500mg/L gibberellin solution for 24 hours or simply soaking them without gibberellin solution, combined with outdoor sand burial for about 90 days.
4. What is the optimal storage condition for Solomon's Seal seeds?
Solomon's Seal seeds should be stored in a cool, dry place to maintain their viability. It is recommended to store them in a sealed container in a refrigerator or other cool storage area.
5. How often should Solomon's Seal seeds be watered during germination?
During germination, Solomon's Seal seeds should be kept consistently moist but not waterlogged. Water them lightly whenever the top layer of soil feels dry to the touch.
6. Can I propagate Solomon's Seal through methods other than seeds?
Yes, Solomon's Seal can also be propagated through rhizome division. Divide healthy rhizomes into sections, ensuring each section has at least one bud, and plant them in a suitable growing medium.
7. Are there any specific pests or diseases that affect Solomon's Seal?
Solomon's Seal can be susceptible to fungal diseases such as powdery mildew and root rot, as well as pest infestations like aphids and spider mites. Proper sanitation and regular inspection can help prevent these issues.
8. How long does it take for Solomon's Seal seedlings to reach maturity?
It typically takes about 2-3 years for Solomon's Seal seedlings to reach maturity and produce flowers.
9. Can I grow Solomon's Seal indoors?
Yes, Solomon's Seal can be grown indoors in containers. Choose a location with bright, indirect light and keep the soil consistently moist but well-drained.
10. Is Solomon's Seal edible?
Yes, certain parts of Solomon's Seal, such as the young shoots and rhizomes, are edible and used in traditional cuisines and herbal medicine.
