Last Updated: 2024/11/22, When tomato is planted in greenhouse, fertilization will be different from that in open field, because the greenhouse environment is limited and the concentration of soil solution may be higher, so there will be some restrictions on fertilization. There may be more base fertilizer in the open field, but fertilization in the greenhouse may be reduced a lot.

When tomato is planted in greenhouse, fertilization will be different from that in open field, because the greenhouse environment is limited and the concentration of soil solution may be higher, so there will be some restrictions on fertilization. There may be more base fertilizer in the open field, but fertilization in the greenhouse may be reduced a lot, depending on the growth of tomatoes and some external environmental conditions.

1. Fertilization method

It is necessary to apply more fertilizer at the seedling stage, but it is more fertilizer-tolerant and mainly grows plants, so it needs more nitrogen fertilizer, combined with potash fertilizer and phosphate fertilizer, and then it can produce a lot of fruit in the fruiting period, mainly a large amount of potash fertilizer, and then a small amount of phosphate fertilizer and nitrogen fertilizer. As a result, more fertilizer is needed in the later stage, which can guarantee the result, and then delay the time of fruit. Fertilization is mainly dissolved fertilization, which is easier to absorb.

2. Amount of fertilizer applied

Generally speaking, the amount of basic fertilizer applied in a greenhouse is about 500 jin, and the first time it is applied at the seedling stage, it is necessary to apply fertilizer at this time, light fertilizer and water is about 50 to 100 jin at a time, about 2 times at the whole seedling stage, and once a month after the seedling stage, the amount of fertilizer application is about 60 jin. If you apply chemical fertilizer, you can decide the amount according to the elements contained in the chemical fertilizer.

3. Environmental impact

If in winter, the outside world is low, you can apply more fertilizer appropriately, and farm manure can keep warm. If the heavy rain affects the water content of the soil, you can wait until some water is lost before applying fertilizer. The high temperature in summer will have the greatest effect on the nutrition in the greenhouse, and the soil temperature will rise. It is necessary to apply fertilizer after cooling to protect the root system and promote absorption.

4. Points for attention

Pay attention to not excessive fertilization, excessive fertilization will increase the concentration of soil solution, the root system will not be able to absorb water and nutrients, fertilization will produce fertilizer damage. Pay attention to fertilization should be used with watering, do not use alone, or can also be watered after fertilization, so that absorption is better. The waste should be used according to the amount of fertilizer needed for tomatoes and according to the fertility of the soil. Do not apply too much fertilizer during flowering, mainly before flowering. The soil is too wet to fertilize.

Tomato greenhouse fertilization should also be based on their own local environment and planting varieties, as well as some influencing elements to fertilize, and finally should pay attention to the weather effects, soil conditions, and then decide to apply fertilizer. It should be used according to the actual situation.
