Compared to other vegetables, eggplant has a longer growth cycle and takes 2-3 months. Therefore, if you want to have a high yield of eggplant, you must grasp the fertilization period of eggplant and apply fertilizer in a targeted manner, so as to improve the fertilizer utilization rate and achieve the purpose of high yield and harvest. In the end, what fertilizer is used for eggplant top dressing, which is easier to obtain high yield?
What fertilizer is used for eggplant top dressing
What fertilizer is used for top dressing of eggplant - after survival to before flowering
Eggplant needs sufficient nutrients after survival, and the application of high-nitrogen water-soluble fertilizer at this stage can quickly supplement nutrients, promote the growth of eggplant branches, leaves, and roots, cultivate strong plants, and lay the foundation for later flowering and fruit setting.
What fertilizer is used for eggplant top dressing - after flowering to before fruit set
At this stage, fertilization should be controlled according to the specific growth of eggplant, if the plant growth is good, less fertilizer or no fertilization; if the growth is not good, the appropriate amount of balanced water-soluble fertilizer can be applied to supplement plant nutrients, promote flower bud differentiation, and improve the flowering and fruit setting rate of eggplant.
What fertilizer to use for top dressing of eggplant - after fruit set to before harvest
At this time, the eggplant fruit begins to develop, the demand for nutrients begins to increase, if the fertilizer is not sufficient, it will cause premature senescence of the plant, so it is necessary to use high-potassium water-soluble fertilizer for top dressing in time, and apply it every 10-15 days until before harvesting. This can promote the expansion of eggplant fruits, improve the accumulation of dry matter, and is conducive to the increase of yield and quality.
What fertilizer is used for eggplant topdressing - root topdressing
Due to the limited absorption of root fertilizer plants, we can spray foliar fertilizer at the seedling stage of eggplant to supplement nutrition and improve stress resistance, spray boron fertilizer at the flowering stage to promote the quantity and quality of flower buds and increase the flowering rate, and spray potassium dihydrogen phosphate + chelated calcium fertilizer at the fruit expansion stage to promote the expansion and color change of eggplant fruits, and increase the yield and quality.
According to the above four fertilization management, nitrogen, phosphorus and potassium are mainly applied to the roots, combined with extra-root topdressing, and an appropriate amount of medium and trace elements are applied to ensure the high yield of eggplant.
