What should you pay attention to when fertilizing tomatoes? A detailed explanation of the latest key points
Tomatoes are the most common vegetable in our daily lives. Their yield is affected by many factors, among which fertilizing is the most critical. Many people do not know much about fertilizing tomatoes. So what should you pay attention to when fertilizing tomatoes? Let us find out together.
1. Control the amount of fertilizer
During the stage from transplanting tomatoes until fruit set, fertilizing should be based on the actual condition of the seedlings, and the amount of fertilizer should be controlled. If too much fertilizer is applied and it is too concentrated, it will cause the seedlings to grow leggy and may even cause the plants to drop flowers and fruit. Therefore, during this stage, except for plants that are especially deficient in fertilizer, the amount of fertilizer 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 fruit on the truss grows 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, pay attention to the fertilizer concentration to avoid fertilizer damage caused by too high a concentration. Generally, apply 30% human manure and urine or 5% sulfur-containing compound fertilizer extract to ensure the plants do not run out of fertilizer. During the fruit expansion stage, in order to meet the plant's later needs and also avoid premature aging caused by lack of fertilizer, fertilizer for preserving flowers and fruit should be applied in time. Generally, every 10 days, apply 40% human manure and urine or 5% sulfur-containing compound fertilizer extract.
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 fruit and seeds. Especially in the later stage, when root absorption capacity declines, foliar fertilizer should be sprayed 2 times in time during the fruit growth period. You can spray organic fertilizer liquid, or spray various trace elements, to improve the yield and quality of tomatoes.
4. Fertilization taboos
When topdressing tomatoes, avoid doing so when the soil is relatively wet or at midday under high temperature, and avoid concentrated fertilization. Concentrated fertilization can very easily cause the plants to grow leggy 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 greater water evaporation from the plant leaves and will greatly affect the release of fertilizer efficiency.
