What are the key points to note when fertilizing tomatoes?
Tomatoes are the most common vegetable in our daily lives, and their yield is affected by many factors, among which fertilization is the most critical. Many people do not know much about fertilizing tomatoes. So what should be noted when fertilizing tomatoes? Let's learn about it together with the editor.
1. Control the amount of fertilizer applied
During the stage from transplanting tomatoes to fruit setting, fertilization should be based on the actual condition of the seedlings, and the amount of fertilizer applied should be controlled. If too much fertilizer is applied and it is too concentrated, it will cause the seedlings to grow excessively and may even cause the plants to drop flowers and fruits. Therefore, during this stage, except for plants that are particularly short of fertilizer, the amount of fertilizer applied generally needs to be controlled. It is enough to apply a little dilute manure water or organic fertilizer liquid. Do not apply large amounts of fertilizer.
2. Promote plant growth
During the young fruit stage and harvest stage of tomatoes, fertilizer should be applied frequently to promote plant growth and development. When the first truss fruits grow to the size of a walnut, quick-acting fertilizer should be applied 1-2 times in time to meet the plant's nutrient needs. At the same time, attention should also be paid to the fertilizer concentration to avoid fertilizer damage caused by too high a concentration. Generally, a 30% concentration of human manure and urine or a 5% sulfur-containing compound fertilizer extract is applied to ensure that the plants do not lack fertilizer. During the fruit expansion stage, in order to meet the later needs of the plants and also to avoid premature aging of the plants caused by lack of fertilizer, flower- and fruit-preserving fertilizer should be applied in time. Generally, every 10 days, a 40% concentration of human manure and urine or a 5% sulfur-containing compound fertilizer extract should be applied.
3. Spray foliar fertilizer
Tomatoes do not only absorb nutrients through their roots; their leaves can also absorb mineral nutrients to promote the growth and development of fruits and seeds. Especially in the later stage, when the root absorption capacity declines, foliar fertilizer should be sprayed 2- times in time during the fruit growth period. Organic fertilizer liquid can be used for spraying, and various trace elements can also be sprayed to improve the yield and quality of tomatoes.
4. Fertilization taboos
When topdressing tomatoes, avoid doing so when the soil is relatively wet or during high temperatures at noon, and avoid concentrated fertilization. Concentrated fertilization can easily cause excessive plant growth and is also prone to causing fertilizer damage. Fertilizing when soil moisture is relatively high can easily cause physiological diseases such as flower and fruit drop, while fertilizing under high temperature conditions will cause a large amount of water evaporation from the plant leaves and will greatly affect the volatilization of fertilizer efficacy.
