Latest Causes of Poor Growth in Early Spring Peppers and Mitigation Measures

In rural areas, basically every household grows peppers, and now is the pepper sowing period, but after sowing, it has been found that pepper seedlings show poor growth. The vigor of pepper seedlings directly affects the later yield, so what causes poor growth of pepper seedlings? Let's learn about it together with the editor.

I. Causes of Poor Growth in Early Spring Peppers

1. Soil compaction

After transplanting, pepper seedlings only grow 2-3 secondary roots, and the cause is soil compaction, which results in poor root growth. When the soil organic matter content in protected cultivation areas is too low, soil compaction worsens, especially in sandy loam soil, where soil permeability is poor, often causing poor growth of pepper seedlings. The effective solution is to increase the application of organic fertilizer, raise the organic matter content, improve soil aggregate structure and permeability, and enhance the soil's water and fertilizer retention capacity.

2. Fertilizer damage

Excessive use of fertilizer during production can also cause seedling burn, and this phenomenon generally causes root rot. If not handled in time, it may cause extensive root burning. Once fertilizer damage occurs, you should promptly hoe and water, diluting the fertilizer concentration through watering.

3. Pesticide damage

There are mainly three ways pesticide damage to peppers occurs. First, after soil chemical treatment, the plow layer is not fully ventilated and aired, leaving more pesticide residue in the soil, which seriously affects seedling growth. Second, when transplanting, excessive pesticide is used in the transplanting holes. Using pesticides to control diseases at transplanting can effectively control pepper seedling-stage diseases, but once the pesticide is used excessively, pesticide damage occurs. Third, when dipping roots at transplanting, the pesticide concentration is too high, causing seedling burn. At transplanting, using Actara, Previcur, foliar fertilizer, and so on to dip the seedlings' roots can control whiteflies, aphids, and so on after transplanting, while also promoting rapid seedling growth. However, once the pesticide concentration exceeds 600 times, seedling burn is very likely to occur, thus causing poor seedling growth.

II. Mitigation Measures

When soil moisture is suitable, you should seize sunny days to plant seedlings. The sunnier the day when transplanting, the more favorable it is for root-soil contact, shortening the seedling recovery period and quickly restoring growth. When transplanting, in addition to watering enough settling water, it is not suitable to water again from seedling recovery until before flowering. During continuous drought, only light watering is needed. When young fruits grow to about 3 cm, irrigation can be done in case of drought, but flood irrigation must be avoided. Peppers like fertilizer but are also afraid of it, and are relatively sensitive to fertilizer, so fertilization should combine organic fertilizer and inorganic fertilizer, and organic fertilizer must be composted and thoroughly decomposed. Nitrogen fertilizer should be applied at the seedling stage, but nitrogen fertilizer must not be applied excessively. At the same time, it should also be combined with phosphorus and potassium fertilizers and trace elements to prevent deficiency symptoms.
