When the peppers grow to 20-30 cm tall or 7-14 pieces, pinch the branches. During the young fruit stage and fruit expansion stage of pepper, vegetative growth and reproductive growth are synchronized at this time, requiring a large amount of nutrient consumption. Fertilization should be focused. Phosphorus and potassium fertilizers can be applied once every 10 days or so. When planting peppers, varieties with tall plants can be planted appropriately sparsely, and varieties with compact and short plants can be planted appropriately densely.

1. Pay attention to preserving flowers and fruits

Spraying naphthylacetic acid or anti-falling solution at a concentration of 50 mg/L during the flowering period of peppers can not only extend the life of the leaves, but also reduce the number of mosaics and leaves. disease, enhance stress resistance, significantly reduce flower drop rate, and increase fruit setting rate and yield by 10-20%.

2. Pay attention to pruning and pruning

When the peppers grow to a height of 20-30 cm or 7-14 pieces, pruning can encourage the peppers to produce more side branches. This will achieve the effect of more fruits and increased yield.

3. Pay attention to fertilizer and water control during the flowering period

During the pepper flowering period, before the flowers bloom and fruit is set, unless the soil is excessively dry or there is a serious lack of fertilizer, appropriate drenching, small watering, and top dressing are required. In addition to applying thin fertilizer, excessive use of water and fertilizer should be avoided.

Otherwise, the pepper plants will grow elongated, resulting in flower and fruit drop problems, which may easily lead to reduced yields.

IV. Pay attention to top dressing during the fruiting period

During the young pepper fruit stage and fruit expansion stage, vegetative growth and reproductive growth are in sync, requiring a large amount of nutrient consumption, and fertilization should be focused. , you can topdress phosphorus and potassium fertilizer once every 10 days or so.

Otherwise, it will easily cause premature plant aging and affect normal flowering and fruiting in the later period.

5. Avoid repeated planting

Pepper is not suitable for repeated planting, otherwise it will aggravate the occurrence of pepper diseases and insect pests, leading to problems such as rotten pepper fruits, rotten roots, and dead trees.

Therefore, when planting peppers, it is best to choose a plot that has not been planted with peppers in the past 3 years. If it is a repeat cropping land, it should be planted in 2-3 rotations with non-nightshade crops such as garlic, soybeans, and green onions. Plant again later in the year.

6. Pay attention to the density of planting

Pepper has a very strong branching ability. If the sowing density is too high, it will easily lead to dense branches and leaves in the middle and late stages, and the field canopy will be closed and airtight, which will not only induce Various diseases and insect pests, and the peppers do not grow large and are of low quality.

When planting peppers, varieties with tall plants can be planted appropriately sparsely, while varieties with compact and short plants can be planted appropriately densely.
