After the pepper is planted, the seedlings are not good.

Recently, some readers have reported that after the pepper is planted, there are phenomena such as long incubation time, weak plants, and yellow leaves. In response to these questions, the author analyzes and answers for everyone.

Cause Analysis

Some vegetable farmers who have been planted in the deep may have to consider watering after planting. They are afraid that the water will wash down the seedlings. Some vegetable farmers have buried almost one-third of the stems in the soil. Due to the high temperature and high humidity, the stems turn brown and even rot, but this is not a disease and cannot be prevented by spraying.

The adaptation process of seedling seedlings has been adapted to the soil environment of the seedbed before planting. After the planting, it has to have a certain time to adapt to the soil environment in the arch shed, which causes the lengthening time of the seedlings to be lengthened.

The method of colonization is not correct. Most of the vegetable farmers have not adopted ridges and colonization, and most of them adopt the method of flooding with large water, and the gas permeability is not good, resulting in roots. When the wilted seedlings are pulled out, it can be clearly seen that some of the capillary roots have been necrotic, and the remaining roots are insufficient to maintain the nutrients and moisture required for their normal growth. When the temperature is high on a sunny day, the amount of transpiration of the plant is large, and the water required is large, so the wilting phenomenon occurs.

Whitefly is harmful to whitefly, which not only absorbs plant juice, but also spreads viral diseases. Because of its strong reproductive ability and rapid reproduction, it is necessary to step up prevention and control.

Prevention

For the case of deep planting, to strengthen the field management, you can use a small tool to dig a digging around the seedlings, so that the stem buried in the soil is exposed to the soil. Appropriate cultivating and slashing, increase soil permeability, avoid rotten stalks, and cause dead trees.

For the phenomenon that the hairy roots of the seedlings are necrotic and no new roots are produced, rooting and seedlings can be added to the roots to prevent the soil-borne diseases and promote new roots as soon as possible.

For whitefly, you must pay attention to prevention in advance, or you can spray in the early stage of insect pests: you can use 25% of chlorpyrifos 1000 times solution, or 1.8% of avermectin emulsifiable concentrate 3500 times solution, 40% of imidacloprid. Foliar spray can be carried out with 4000 times solvent. It is best to add Plex and some fungicides at the same time as spraying to prevent the occurrence of diseases and some bacterial diseases.
