It is recommended that fruit trees be fertilized multiple times a year
Recently, the author visited some fruit producing areas and found that some local farmers are still adopting some unreasonable fertilization methods in production. “One shelling†is one of them. The so-called fertilization "one shelling" refers to the application of organic fertilizer and inorganic fertilizer in the autumn, and the fruit tree is applied once, and no fertilizer is applied in other seasons. Fertilization of fruit trees cannot be “one shot†because this method of fertilization does not meet the characteristics of the fruit trees for the anniversary.
Generally, the northern deciduous fruit trees are crops with a long growth cycle. The absorption of the three main elements of nitrogen, phosphorus and potassium is the peak of nitrogen absorption in spring. The fruit expansion period after fruit setting is the absorption of potassium before harvesting. At the peak, the absorption of phosphorus was relatively flat during the anniversary, with no obvious peak period. In view of the characteristics of this fertilizer requirement, it is not appropriate to apply the inorganic fertilizer to the fruit tree at any time. For example, in the autumn, if the nitrogen and potassium fertilizers needed for the whole year of the fruit tree are mixed with the organic fertilizer, it is not applied at the same time, and this is not the peak of the absorption of nitrogen and potassium in the fruit trees. The applied nitrogen and potassium are for the fruit trees. In excess, the inorganic nutrients that the fruit trees can't use will be fixed or lost in the soil. In the next year, the demand for nitrogen or potassium in the fruit trees will be insufficient. For fruit trees, for every 100 kilograms of fruit produced, there is a scientifically determined reasonable absorption ratio of nitrogen, phosphorus and potassium. According to this ratio, considering the absorption rate and the proportion of loss of fertilizer, it is possible to give a variety of inorganic The amount of fertilizer applied. However, this amount of fertilization is not the amount that is applied to the fruit trees at one time, but refers to the amount of fertilizer applied to the fruit trees throughout the year. Fertilization of fruit trees should refer to the fertilization amount and the characteristics of nutrient requirements of fruit trees in different periods of the year, and focus on the application of fertilizers of different compositions in stages.
Some fruit farmers fertilize “one shellingâ€, which confuses the characteristics of organic fertilizer with the characteristics of inorganic fertilizer. Organic fertilizers generally require a one-time application of fruit trees after fruit picking because the fertilizer efficiency of organic fertilizers is relatively long-lasting, and the main purpose of application is to improve the soil environment. Inorganic fertilizers are characterized by quick-acting and short-term duration. It is best to apply them according to the requirements of fertilizer requirements in different periods of fruit trees in a year.
To create the ideal environment for your fish, proper and regulated light in the aquariums is of premier importance. Fish thrive under proper light but in relative moderation.This means that considerable thought and a modest investment will be required to keep your tank well lit, both for your pleasure as well as the fish.
The light in an average home is generally not enough for the fish living in an aquarium. Living all day and all night in that environment will not be conducive to the fish`s health or even their temperament. Like humans, fish thrive in a warm and pleasant atmosphere. Statistics definitely prove that fish living in a well lit aquarium certainly live longer and appear to be more energetic which must cause us to assume that they are happy.
