1. How to do reasonable fertilization? Rational fertilization is to pay attention to timely and appropriate fertilization. Timely refers to the fact that flowers need fertilization before fertilizing. The indicator of fertilization was found to be a weak growth of the flower plants and a pale leaf color. As far as what fertilizer is applied, it depends on the different growth stages of different flowers. How is the right amount of fertilization? In the seedling stage, it is best to apply some nitrogenous fertilizer to promote the vigorous growth of young seedlings; it is best to apply some phosphate fertilizer during the bud to promote flower buds and strong seeds; the amount of fertilizer should be controlled at the early fruit setting stage. All in all, no matter what period of fertilization should pay attention to the amount of use, if too much nitrogen, so that plants tend to be prolonged; too much potash fertilizer, will hinder flower fertility, affect the flowering results. 2. What are the principles followed by rational fertilization? (1) Fertilizer must distinguish between different kinds of flowers. Different types of flowers have different requirements for fertilizers. The foliage-dominated flowers may emphasize nitrogen fertilizer; the flower-seeing flowers need to apply proper amount of fertilizer during the flowering period; the fruit-seeking flowers should control the amount of fertilizer and water during the flowering period; and the fruit should be supplied with sufficient fertilizer to achieve the desired result. effect. (2) Fertilization varies with seasons. Winter temperatures are low, flower plants grow slowly, and generally do not fertilize; spring and autumn flowers are in a growing season and should be increased in amount; top summer temperatures, rapid evaporation of water, most The flower is in a vigorous growth period, the number of chasing moons increases, and the concentration should be small. (3) Application of Organic Fertilizers Do not use organic fertilizers to avoid the use of unripe fertilizers. It must be fully decomposed before it can be applied. 3. Why can't I apply uncooked fertilizer? Some flower lovers often put some egg shells, animal organs, cake fats, raw horse dung, etc. buried in basin soil. By increasing soil nutrients in such a way, the result is counterproductive, not only failing to achieve the envisaged purpose, but also harming the flowers. The reason for this is that the process of flower growth absorbs various nutrients such as nitrogen, phosphorus, potassium and magnesium that have been fermented and dissolved in water. The corrupt food or some animal excrement added to the potted soil is directly buried in the pot without fermentation. When the water is decomposed and fermented, it will produce high temperature and directly burn the root of the flower, together with the activities of the microorganisms, so that the soil is seriously deprived of oxygen. , Which eventually led to the death of the flower. At the same time, odors produced during the fermentation of unrefined fertilizers are prone to induce fly spawning. The locusts are very likely to bite the roots. To endanger the flowers and cultivate flowers, it is necessary to apply sufficient decomposing fertilizer to ensure good flower growth. 4. What are the benefits of extra-fertilization? The most obvious advantage of top dressings outside roots is that they can quickly exert significant fertilizer effects with less fertilizer, and the fertilizers will not be fixed and not affected by the root absorption function. In general, after spraying inorganic fertilizer on the foliage, it can be absorbed in 5 hours. The fertilizer effect can last for 7 to 10 days. Therefore, the top dressing should be sprayed every 7-10 days. In addition to flowering, the rest of the growth phase can be extra-root fertilizer. 5. What matters should be paid attention to after top dressing? (1) Not all fertilizers can be used as top-dressing fertilizers. Only some fertilizers with good solubility can be used as top-dressing fertilizers. (2) Fertilizer concentration is relatively low when dressing topically. For example, the concentration of ferrous sulfate is 0.2%-0.5%, the concentration of superphosphate is 1%-3%, and the concentration of urea is not more than 0.1%. (3) In general, it is best to select extra-root fertilizers in the morning or in sunny and windless weather. The most suitable time is after 3:00 p.m. Do not apply fertilizer at noon to avoid burning the leaves. (4) Spray the foliage as evenly as possible, because the back of the leaf contains a large number of pores, the absorption is faster than the leaf surface, and the back of the leaves is preferably sprayed to the fertilizer solution. The amount sprayed leaves the leaf surface wet. (5) The fertilizer must be uniformly dissolved, and insoluble substances must be filtered out. Can you also use fungicides and pesticides? The use of Kun, so that we can prevent diseases and insect pests in a two-pronged approach. Disclaimer: Some articles in this website have been transferred from the Internet.
