Seedling growth is generally divided into four stages: seedling stage, seedling stage, fast growth stage, and hardening stage. Seedlings in the seedling stage cannot produce nutrients on their own, and their nutrient sources depend on nutrients stored inside the seeds. The seedling stage is more sensitive to phosphorus and nitrogen, and is generally dominated by partial nitrogen fertilizer to promote seedling preservation and root growth. The fast-growing period is the period when the seedlings grow most vigorously. The maximum amount of fertilizer and water is needed. The amount and frequency of nitrogenous fertilizer application can be increased, and phosphorus and potassium fertilizers can be applied in proportion to promote nitrogen absorption and seedling growth. In the later stage, in order to promote the hardening of seedlings and increase their resistance, nitrogen fertilizer should be stopped in due course. When the seedlings are gradually hardened in the upper and lower parts of the seedlings, they must prevent leggy, stop using fertilizers, and increase seedling resistance. Irrigation usually takes place in the evening. Irrigation should not be done if the temperature is too high. Application of farmyard fertilizer must be fully skilled, so as not to burn seedlings, but also to kill the bacteria and insect pests in the eggs. The top dressing is usually 1 or 2 times a week, and it is better to work in the early morning. For some trace elements, soil application is often ineffective. Therefore, it is possible to use extra-root fertilizers in combination with the two topdressing methods. Either way, it should be light and heavy. Once excessive fertilization is found, it should be diluted as soon as possible. Dingmin Pharmaceutical supply Indacaterol API and Indacaterol Intermediates with high purity and best price.
