What are the benefits of foliar topdressing for fruit trees? Latest analysis
When we grow fruit trees, topdressing is essential. Reasonable topdressing is meant to meet the nutritional needs of fruit tree growth and development, and the topdressing methods for fruit trees are divided into many kinds. For example, furrow application, band application, etc. Among them, the more special one is foliar topdressing. Foliar topdressing means spraying leaf fertilizer, which is very beneficial to the growth of fruit trees. So what are the benefits of foliar topdressing for fruit trees? Let's take a look together below!
1. Direct absorption
The main fertilization method of foliar topdressing is applying leaf fertilizer, because the leaf growth capacity of most fruit trees is relatively strong. When leaf fertilizer is applied, the leaves can directly absorb nutrients. Then they provide nutrition to the plant, directly transporting it to all parts of the plant's growth. It can also enhance the growth capacity of the leaves, improve the photosynthesis of the leaves, and increase the accumulation of photosynthetic substances in the plant. If it is root topdressing, then fertilizer may be fixed in the soil, reducing the conversion rate of the fertilizer and causing the fertilizer effect to decline.
2. Enhancing fertilizer efficiency
The root absorption capacity of some fruit trees is relatively weak. If fertilizer is only applied in the roots, then for those fruit trees with weak root absorption capacity, not only is the conversion rate very low, but it also consumes too much fertilizer and increases planting costs. So for these crops, reasonably applying leaf fertilizer can effectively increase the fertilizer efficiency of the fertilizer, improve the conversion rate of the fertilizer, promote flowering and fruiting, and ensure planting benefits. Moreover, if the proportion of phosphorus and potassium fertilizers, etc. is reasonably increased in the leaf fertilizer, it has a clear effect on increasing yield.
3. Fast leaf conversion
Leaves not only have a strong ability to absorb nutrients, but the conversion of fertilizer is also far higher than that of the roots. It can promptly meet the fruit tree's demand for some nutrients. For example, when we apply calcium fertilizer to the roots, the conversion time takes about 5 days. But if a calcium-containing leaf fertilizer is applied to the leaves, then its conversion time only takes about two days. So for some fruit trees or other crops showing nutrient deficiency symptoms, applying leaf fertilizer can replenish the missing nutrients in the fruit trees as quickly as possible and promote the growth of the fruit trees.
4. Can be mechanized
Compared with root topdressing, foliar topdressing is more convenient to operate, can be managed mechanically, is economical and practical, and has obvious effects. When doing foliar topdressing, the dosage is generally only about 1/10 of the dosage of root topdressing. Moreover, when applying leaf fertilizer and water-soluble fertilizer, they can also be mixed with some pesticides, which not only provides nutrition to the plant but also enhances the plant's disease resistance. In addition, mechanized fertilization has good efficiency, and the overall calculated cost is also relatively low. It is not only suitable for fruit trees, but tea, vegetables, etc. are also very suitable.
The above is a brief introduction to the benefits of foliar topdressing for fruit trees. Although there are many benefits of foliar topdressing for fruit trees, it cannot be used entirely as the method of foliar topdressing. It must be combined with root topdressing to ensure that the growth nutrition of the fruit trees is sufficient and comprehensive. That is all for today's introduction.
