The absorption of nutrients by tomato is relatively large and increases with the growth and development of the plant and the increase of flowering results. The absorption period of nutrients is at the peak of the result. After the first fruit is set, combine the watering to apply a fruit fertilizer. Per acre can apply 15-20 kilograms of urea, superphosphate 20-25 kilograms, or 20-30 kilograms of diammonium phosphate. Potassium sulfate 10 kg should be applied when potassium is lacking. 1000 kg of composted human excreta and 100 kg of plant ash can also be used instead of fertilizer. Later, when the second ear and the third ear begin to expand rapidly, they are top-dressed one at a time. When the fourth ear of the elevated cultivation starts to expand rapidly, it must also be topdressed. Top dressing can be buried deep, or it can be poured with water. The former should pay attention to deep application and sealing, while the latter should pay attention to the amount of fertilizer to prevent burning seedlings. Tomato cultivation in addition to soil topdressing, but also for foliar dressing. For top dressing, 0.2%-0.4% of potassium dihydrogen phosphate, or 0.2%-0.3% of urea, or 2% of superphosphate calcium solution can be sprayed on the surface. The rapid expansion of fruit such as fertilizer and water is insufficient, the fruit development is not neat, the fruit becomes smaller, and the yield is significantly reduced.
