When is it appropriate to top-dress chili peppers
Regarding the experience of when it is appropriate to top-dress chili peppers in the aspect of green plant maintenance, the editor will introduce it next.
When is it appropriate to top-dress chili peppers
The process of top-dressing chili peppers can be divided into several stages. When the seedlings have 1-2 true leaves, apply some ripe human manure or 0.1% urea solution. During the first flowering period, use dung water or nitrogen fertilizer. During the production period, use organic fertilizer. It is important to top-dress during these stages. It should be noted that fertilizing in autumn should not be too late, otherwise the temperature will drop and the fertilizer will not work.
Timing of chili pepper top-dressing
1. Seedling stage top-dressing: Early maturing chili pepper varieties benefit from top-dressing during the seedling stage to promote growth and improve seedling quality; top-dressing during the seedling stage depends on soil fertility. Timely application is needed when the seedbed fertility is insufficient, otherwise it will affect the differentiation of chili pepper flower buds.
2. When 1-2 true leaves appear: When 1-2 true leaves appear, apply some ripe human manure or 0.1% urea solution, and a small amount of phosphorus and potassium fertilizer at the same time. After top-dressing, it is recommended to spray water once to rinse the manure attached to the leaves clean to avoid leaf damage.
3. Top-dressing during the first flowering period: During the first flowering and fruiting period of chili peppers, the basic fertilizer in the soil is consumed by the chili plants. To promote plant growth and produce quality chili peppers, 1800 kg of dung water or 8-9 kg of nitrogen fertilizer is needed per mu.
4. Top-dressing during the production period: When chili peppers enter the peak production period, it is also necessary to apply fertilizer appropriately to ensure the nutrients needed by the chili plants, which can effectively extend the harvesting period. If precision farming is practiced, combine 1800 kg of organic fertilizer per mu with one tillage and soil cultivation, while controlling weeds.
Top-dressing time for chili pepper seedlings
Because Sichuan pepper seedlings are also raised first and then transplanted to the field, one week after transplanting, that is, after planting, top-dressing nutrients are needed to provide nutrients for the chili seedlings. Although a basic fertilizer has been applied to the soil, it is not easily absorbed when the chili root system is weak. At this time, foliar application or root-promoting top-dressing can promote the expansion of the chili root system.
Top-dressing during the chili growing period
1. Planting stage: It is suitable to add additional fertilizer at this stage to promote the survival and growth of chili seedlings, promote rapid growth of seedlings, and increase the number of roots.
2. Vegetative growth stage: It is recommended to use balanced water-soluble fertilizers and foliar sprays to balance plant nutrition, improve leaf photosynthesis, and prevent leaf yellowing.
3. Pre-flowering stage: Chili peppers require a large amount of fertilizer during the flowering period. At this time, foliar application of vegetable-specific fertilizers can improve flowering quality and increase fruit setting rate.
4. Young fruit stage: Spray a large amount of specialized vegetable nutrient agents evenly on the leaves every 5-7 days, and continue to spray for more than 2 times.
Chili pepper top-dressing fertilizers
1. The first top-dressing should be done 3-4 weeks after sowing, when the chili peppers are in the process of turning from green to yellow and then back to green after planting. Small fruits have already blossomed, and there are many branches at the base of the main stem, indicating that the root system is developed, each branch has 4-5 layers of leaves, and the fruit development accelerates.
2. The second top-dressing should be done 5-6 weeks after sowing. At this time, the root system is developed, the absorption capacity is strong, and the leaf photosynthesis rate is the highest. Meanwhile, alternating sprays of flower-promoting agents, vegetable kings, green leaf agents, melon longevity, and compound fruit expansion agents have a good effect on the leaves.
High-yield chili pepper top-dressing methods
1. Light application of seedling fertilizer: It has a good promoting effect on the early development of chili pepper seedlings. Generally, after transplanting, it should be combined with tillage and fertilization, applying an appropriate amount of fertilizer.
2. Flower bud fertilizer application: From the appearance of flower buds to the first harvest, the plants have a large number of flowers but not many fruits. During this period, apply an appropriate amount of fertilizer to meet the needs of chili flowering and fruiting, preventing excessive top-dressing that can lead to excessive plant growth and flower drop. Generally, 1000 kg of fertilizer per mu, 5-8 kg of urea, and 7-8 kg of phosphate fertilizer can be applied.
3. Heavy application of flower and fruit fertilizer: Generally, apply 1500-2000 kg of livestock and poultry manure, 25-40 kg of phosphate fertilizer, and 10 kg of urea per mu. Since the amount of fertilizer is large, the fertilizer should be applied 6-10 centimeters away from the root zone of the plant group to avoid burning the roots. Generally, use once every 15 days, 4-5 times in total.
4. Early application of autumn turning fertilizer: Autumn turning fertilizer is very important for mid-late maturing varieties. Applying autumn turning fertilizer can promote the late maturity of autumn chili peppers and increase yield. Generally, apply once before and after the start of autumn and summer, 1000 kg of animal fertilizer and 20 kg of NPK compound fertilizer per mu. The application should not be too late, otherwise the temperature will drop and the fertilizer will not work.
