First, the symptoms of pepper burning root, mainly in the seedling stage and adult stage. When root burning occurs, the root tips turn yellow and no new roots are produced. In the early stage, the roots are generally not rotted. The growth is slow in the shoots, and the plants are short, brittle, and hard to form small old seedlings. Some seedlings begin to burn roots to 7- The high-temperature season in August only appeared. The light-burning plants napped at noon and recovered sooner or later. Due to the high temperature and lack of water supply in the later period, the plants were dry, and they seemed to have bacterial wilt or blight. No abnormality was found in the longitudinal stems, which was different from the above two diseases.
Second, the cause is mainly the application of excessive organic fertilizer is not fully cooked, in particular the application of inadequate chicken manure or in the case of insufficient water supply in the case of soil, pepper is more prone to burning root.
Third, prevention and control measures
1, the use of formula fertilization technology, the application of enzyme composting compost or bio-organic compound fertilizer, can be used for human excrement preparation, it is best not to use chicken excrement must be used must be fully cooked. The formula has a ratio of 4.5 kilograms of nitrogen, 1.04 kilograms of phosphorus, and 5.5 kilograms of potassium per 1,000 kilograms of pepper fruit. Local diets can be added or subtracted according to local conditions.
2. Advocate the use of Huimanfeng multi-element composite organic active liquid fertilizer, with 450 ml of mu, 400 times dilution or 3000 times of Yunda-120 plant growth regulator, and 3 sprays of leaves.
3. When burning has occurred, increase the amount of water and reduce the concentration of soil solution.
4. Fields covered with mulching film should gradually break the membrane after entering the high temperature season to prevent the ground temperature from being too high. If necessary, increase the amount of bleed air or reduce the temperature by watering.
