How to fertilize eggplant? Master these precautions
Fertilizing eggplant is an essential management task in cultivation. Fertilizing can effectively supplement the nutrients eggplant needs for growth, and can also prevent a shortage of a certain nutrient in the soil from affecting eggplant growth. Eggplant has a long growth cycle, so fertilizing is especially important. In fact, there are many things to pay attention to when fertilizing. Below, the editor brings you the precautions when fertilizing eggplant. Let's take a look!
1. Watch the dosage
Eggplant's nutrient needs change at different growth stages. For example, during the full fruiting period, eggplant's demand for nitrogen is very high. So when fertilizing during the full fruiting period, we should apply more nitrogen fertilizer. However, in high-temperature summer conditions, we should follow the principle of applying small amounts frequently. Because high temperatures speed up the conversion of nitrogen fertilizer, and after the plant has absorbed enough, the excess fertilizer will gradually be lost, especially when planting in sandy soil, where fertilizer use efficiency drops greatly. It may also cause the plant to grow leggy. Nitrogen fertilizer should not exceed 40 jin per mu, usually once every 5 days, applied together with watering.
2. Trench application
Eggplant topdressing fertilizers include organic fertilizers, chemical fertilizers and foliar fertilizers, but each type of fertilizer has a different application method. Many friends, when applying chemical fertilizers, apply them by washing them in with water just like organic fertilizers. Fertilizing this way can affect eggplant growth in hot weather. Because in high-temperature conditions, the ammonia element in chemical fertilizers decomposes very easily, especially ammonium bicarbonate. The ammonia gas produced by decomposition reduces the fertilizer's effect and can also poison the plant, and in severe cases kill it. So when applying chemical fertilizers, we should use the trench application method. After fertilizing, cover with soil and water, fully diluting the fertilizer.
3. Reasonable formula
Although eggplant prefers nitrogen, when fertilizing we cannot over-apply or apply only nitrogen fertilizer; we must also combine it with an appropriate amount of phosphorus and potassium fertilizer. When topdressing, we must not apply only nitrogen fertilizer just to promote plant growth; it should be combined with phosphorus and potassium fertilizer at least 2 times or more. Only in this way can we ensure comprehensive nutrition for eggplant, increase eggplant yield, enhance quality, and extend eggplant's growth cycle. We should also pay attention to the application of trace elements. Although micro-fertilizers are toxic, as long as they are kept within a reasonable range, they will not harm eggplant growth and will even help promote it.
4. Atomized spraying
Atomized spraying is mainly for applying foliar fertilizer. Applying foliar fertilizer can promote leaf growth and increase the amount of chlorophyll. This helps eggplant photosynthesis and increases nutrient accumulation in the plant. Atomized spraying ensures that the foliar fertilizer is sprayed comprehensively and evenly. When spraying, you should not only spray the leaves but also spray the eggplant surface appropriately. This can promote fruit expansion and nutrient absorption. Atomized spraying can also maximize fertilizer use efficiency and reduce fertilizer consumption.
The above is a brief introduction to the precautions when fertilizing eggplant. Part of the reason many friends fail at growing eggplant is that they do not use a correct fertilizing method. Fertilizing is not only very important but also a skilled task, so we hope everyone can master the correct fertilizing method and avoid unnecessary losses. That is all for today's introduction.
