In the spring of March, the earth warmed up and went to the vegetable nursery. However, vegetable growers recently reported that the peppers they planted had seedlings with slow seedlings, stiff seedlings, wilting growth, and falling fruit. The fruit shape of the knots was unusual, and the shades were different, which greatly affected economic efficiency. To this end, our reporter specifically asked Yu Hongzhang, a senior agronomist of the province.
Yu Hongzhang said that this is a common physiological disorder of pepper. There are many direct causes. Except temperature, light, and atmospheric environmental factors, most of them are human factors such as fertilizer and water imbalance. Specific exclusion mitigation measures are as follows:
First, grab a clean seedling. When the soil moisture is moderate, grab the fine seedlings. The more sunny the transplant is, the more conducive to root and soil anastomosis, shorten the slow seedling period, and quickly restore growth. At the same time, transplanting Daejeon should be done in a narrow box, deep trench or sorghum cultivation to facilitate drainage.
Second, appropriate watering. In addition to setting the root water when transplanting the seedlings, the seedlings are generally no longer watered until flowering. Mild watering is required for continuous drought. When the young fruit grows to about 3 centimeters in length, in case of drought, can be furrow irrigation, wet management, avoid flooding irrigation.
Third, fine fertilization. Pepper is fat and afraid of fertilizer, and it is very sensitive to fertilizer. One must do organic fertilizer and inorganic fertilizer application, organic fertilizer must be fully decomposed; the second is due to soil due to the discretion of the application of nitrogen fertilizer, in particular, can not be excessive application of urea; three should be coupled with phosphorus and potassium and trace elements to prevent "green out" Symptoms and other symptoms occur; Fourth, to avoid high temperatures, with a decomposed manure low-concentration water manure; five to prevent defertilizer to ensure adequate nutrition throughout, prevent the "green lack" yellow.
