When growing peppers, controlling plant growth is key to increasing yields. Overly vigorous plant growth can lead to delayed and reduced flowering and fruiting of peppers, as well as pests and diseases, as well as lodging of plants. Therefore, the following points need to be paid attention to when fertilizing and watering:
1.Moderate fertilization: Nitrogen fertilizer is the main nutrient element that promotes plant growth, but too much nitrogen fertilizer can cause plants to be too lush and affect flowering and fruiting. Therefore, it is necessary to avoid excessive application of nitrogen fertilizer in fertilization, especially at the seedling stage, to reduce the amount of watering to prevent overnutrient overgrowth and stunted root development.
Additional expansion: In addition to nitrogen fertilizer, pepper plants need the right amount of phosphorus and potassium fertilizer to maintain normal growth, flowering and fruiting. Phosphorus is an important element for the growth of pepper plants, which can promote root development and improve the quality of fruits. Potassium fertilizer can increase the stress resistance of plants and the sweetness of fruits. Therefore, it is necessary to use phosphate and potassium fertilizers rationally when fertilizing to maintain the nutritional balance of plants and improve yield and quality.
2.Pruning control: For large-fruited peppers, overly lush plants can affect fruit growth and yield. Therefore, pruning can be used to control plant growth, keep 3 or 4 fruiting main branches, and cut off other branches, so as to promote flowering and fruiting.
Additional expansion: Pruning can also improve the ventilation and light transmission of the plant, reducing the chance of pests and diseases. In addition, pruning can also adjust the size and distribution of the fruit, making the yield more balanced.
3.Timely nutrition: Experienced farmers mentioned that an additional 10 kg of urea per mu can be applied during the summer season, which can effectively promote the later fruiting of peppers and greatly increase yields.
Additional expansion: Urea is a fertilizer with a high concentration of nitrogen, which can provide the nutrients needed by plants to promote plant growth, flowering and fruiting. Supplementation of urea at this time can allow plants to make better use of nutrients and increase yield.
Peppers have a long fruiting period, in order to prolong the fruiting period and prevent premature plant senescence, the following measures can be taken:
1.Fertilization supplement: Spray potassium dihydrogen phosphate foliar fertilizer to pepper plants at the peak fruiting stage, adding 5 ml of 001% brassin. This promotes the root development of the plant, effectively resists the risk of premature aging, and thus increases the yield.
Additional amplification: Potassium dihydrogen phosphate is a fertilizer rich in phosphorus and potassium that can provide the nutrients needed for pepper growth, root development and fruit growth. Brassin can promote nutrient absorption and photosynthesis of plants, increase the photosynthetic efficiency of leaves, and thus improve the yield and quality of fruits.
2.Reasonable watering: Peppers have a greater demand for water in the peak fruiting period, and if the ** is insufficient, it is also easy to lead to premature aging. Therefore, in irrigation, it is necessary to reasonably control the water and water it in time.
Additional expansion: When irrigating, avoid overwatering and frequent watering, so as not to cause root suffocation and disease breeding. At the same time, it is necessary to ensure that the irrigation is evenly watered to avoid stagnant water, which can cause root rot and plant lodging.
3.Top application of ternary compound fertilizer: Appropriate topdressing of ternary compound fertilizer in the peak fruiting period, about 25 kg per mu, to meet the water and nutrient needs of peppers after flowering and fruiting.
Additional expansion: Ternary compound fertilizer is a fertilizer that fully contains nitrogen, phosphorus and potassium, which can provide comprehensive nutrients needed for plant growth and increase the yield and quality of fruits. Pepper has a greater demand for nutrients in the peak fruiting period, and the topdressing of ternary compound fertilizer can meet its needs and ensure the healthy growth of plants and the development of fruits.
Maintaining the flowers and fruits of peppers is the key to increasing yields, and the following points are important measures to keep the flowers and fruits abundant:
1.Control the cultivation density: avoid excessive cultivation density, control the row spacing at 40 50 cm, and the plant spacing at 30 40 cm. Over-dense cultivation will cause pepper plants to be too closed, which can easily lead to flower and fruit drop.
Additional expansion: Reasonable cultivation density can ensure sufficient ventilation and light between plants, reduce the occurrence of pests and diseases, improve the efficiency of pollen dispersal, and increase the fruit setting rate.
2.Reasonable fertilization: In the young fruit stage, pepper has a greater demand for water and nutrients, and if it is insufficient, it is easy to lead to flower and fruit drop. Therefore, timely watering and topdressing of ternary compound fertilizer can meet the growth needs of peppers and maintain the good development of flowers and fruits.
Additional expansion: When fertilizing, it is necessary to ensure that the fertilizer is fully dissolved and absorbed to avoid waste and pollution of the environment. At the same time, it is necessary to pay attention to the choice of fertilization time to improve the fertilization effect and reduce the loss of fertilizer.
When planting peppers, it is necessary to pay attention to avoiding heavy cultivation and using fertilizers correctly to ensure the high yield and quality of peppers
1.Avoid heavy cropping: Plots that have not been planted with Solanaceae vegetables for 2 to 3 years should be selected to prevent the accumulation of pathogens in the soil and reduce the risk of disease.
Additional expansion: Heavy cropping cultivation can easily lead to the increase of pests and diseases in the soil, therefore, when planting peppers, it is necessary to pay attention to crop rotation and reasonable selection of planting sites, and avoid continuous planting of Solanaceae vegetables to reduce the pressure of soil diseases and pests.
2.Correct use of fertilizer: The use of unrotted farm manure is easy to cause root burning and an increase in pests and diseases, so the use of well-rotted farm manure can better provide nutrients for peppers.
Additional expansion: Uncooked farmyard manure contains high salinity and strains that can easily cause damage to plant roots and growth. Therefore, when applying fertilizer, it is necessary to choose well-rotted farmhouse fertilizer, or use a mixture of organic fertilizer and chemical fertilizer to provide the nutrients needed by the plant and promote the growth of the plant and the development of the fruit.
3.Avoid chlorine-containing fertilizers: Chlorine-containing fertilizers should not be used because high chloride concentrations will reduce the plant's resistance to pests and diseases and fruit development.
Additional amplification: Ammonium chloride, potassium chloride and chlorine-containing compound fertilizers are commonly used chlorine-containing fertilizers, which are not suitable for fertilization of peppers. Choose chlorine-free fertilizers, such as ammonium sulfate, potassium sulfate, etc., to meet the nutrient needs of pepper plants.
To sum up, planting high-yield peppers requires mastering scientific fertilization and irrigation skills, reasonably controlling plant growth and cultivation density, and avoiding heavy cultivation and the use of unsuitable fertilizers. Through these measures, the yield and quality of peppers can be effectively improved. It is also important to make adjustments and improvements based on the actual situation and experience to obtain better planting results.
