The main advantages and disadvantages of foliar fertilization are that the leaves absorb faster than the roots and can quickly provide nutrients to the plants. However, the shortcoming is that the application rate is limited and the effect is relatively short. The efficiency of leaf nutrition is related to the leaf structure, and the leaf has low permeability to mineral nutrients, especially the leaves with thick keratin. Leaves of crops such as olives, citrus and coffee. The fertilizer drops do not easily penetrate into the leaves, and the water droplets of the liquid fertilizer slide down from the surface, causing loss. If it is raining soon after spraying, the rain will lose the liquid fertilizer, and the high temperature spraying in the windy weather will cause the fertilizer to dry quickly on the leaf surface, which may reduce the effect of foliar fertilization.
In addition, its advantages are: direct supply of nutrients, avoiding the fixation and degradation of nutrients in the soil, and the efficiency of nutrient use is higher than that of soil fertilization.
The disadvantage of foliar fertilization is that the fertilizer effect is short-lived and it is an auxiliary fertilization method.
Foliar fertilization should master the skills to choose fertilizer components, foliar fertilization is mainly to supply trace elements, but a large number of trace elements combined to facilitate the absorption and utilization of nutrients. To determine the variety of fertilizers, one must be regarded as the demand for the goods. Second, it is necessary to look at the soil to limit the types of nutrients, improve the pertinence of foliar fertilization, and not choose the replenishing solution of Shiquan, which is expensive and non-targeting, and the effect is not good. For example, to solve the problem of chlorosis of new leaves in northern peanuts, it is necessary to spray iron; etc.; to increase the 1000-grain weight of winter wheat during the grain filling period, spray urea and potassium dihydrogen phosphate.
The concentration of leaf fertilizer should be fixed. If the concentration is too high, it will damage the leaves, but it will reduce the fertilizer efficiency. If the concentration is too low, it will not work.
The time and climatic conditions of the fertilizer application should be selected, for example, to avoid spraying before the rain; during the growth period, the key period of nutrition and efficiency should be selected.
The number of times of spraying fertilizer is generally required to be sprayed twice or more, and the specific number is determined according to the effect.
