What methods can increase peanut yields? Please explain
To increase peanut yields, you can refer to the following methods:
1. Clearing the seedlings and hardening them off
After peanuts emerge, scrape the soil around the base of the seedlings outward so that both cotyledons are exposed above the ground. This allows the first pair of lateral branches of the peanut to develop early, shortens the internodes of the stem, achieves strong seedlings, and advances flower bud differentiation, which is beneficial for high yield. When clearing the seedlings, timing and depth must be well controlled. The timing is when the seedlings have basically emerged uniformly and two true leaves are visible on the main stem. If done too early, the seedlings are tender and have weak resistance to the external environment; if done too late, the lateral branches are thin and weak and the purpose of clearing the seedlings cannot be achieved. The depth should be based on exposing both cotyledons above the soil surface. If too shallow, the first pair of lateral branches remains buried in the soil and the effect of clearing the seedlings cannot be achieved; if too deep, the embryo bud is easily scraped out, causing the seedlings to lodge, which is unfavorable for growth and development. Intertillage and loosening of the soil can only be done 15 days after clearing the seedlings.
2. Pressing rings around the whole plant
At the beginning of the flowering stage, in combination with hoeing and clearing the seedlings, press wet soil onto the base of the peanut plants so that each hill of peanut plants faces three directions, causing the peanuts to grow directionally at an angle to the ground surface. Around the time the peanut rows close and at the beginning of the flowering stage, use a ring about 30 cm in diameter and press it over the central part of each peanut hill, causing them to creep along the ground surface in three different directions. In this way, diseases can be reduced compared with conventional cultivation. Branch growth is better, the fruiting range increases, and generally peanut yields can be increased by about 15%.
3. Timely soil scattering
When a large number of pegs of the peanut are entering the soil, some pegs cannot enter the soil, and some pegs stop growing as soon as they contact the soil. At this critical moment, scooping up fine wet soil on the spot and scattering it from above can increase the rate of pegs entering the soil, the pod-setting rate, and the full-pod rate.
4. Topdressing calcium fertilizer
During the pod-filling stage, peanuts need large amounts of calcium and phosphorus. Applying gypsum and superphosphate is beneficial for shell formation, increases the full-pod rate, and raises the oil content of the seeds. The method is: after the pegs enter the soil, combine with irrigation; for alkaline soil, apply 5 kg to 15 kg of gypsum per mu, and for neutral soil, apply superphosphate. If a 2% superphosphate solution is also used for foliar spraying, the effect is even better.
5. Increasing boron fertilizer and molybdenum fertilizer
Production practice has shown that applying boron fertilizer and molybdenum fertilizer to peanuts can generally increase yields by more than 10%.
