High-yield fertilization technology for tomato

One, tomato needs fertilizer characteristics

Tomatoes need more fertilizer and are resistant to fertilizer. The production of 6600 pounds of tomatoes per acre requires absorption of 18.6 pounds of nitrogen from the soil, 8.6 pounds of phosphorus, and 24.6 pounds of potassium. The ratio of the three is 1:0.46:1.32.

The tomato is dominated by nitrogen at the seedling stage. At the beginning of the first fruit, the absorption of nitrogen, phosphorus, and potassium rapidly increases. Nitrogen accounts for 50% of the three elements and potassium only accounts for 32%. At the beginning of the harvest, nitrogen accounts for only 36%, while potassium accounts for 50%. Tomato from the set fruit requires potassium to rise linearly, and the potassium absorption during the fruit enlargement period accounts for more than 70% of the total potassium needed for the whole growth period, until the absorption of potassium is slightly reduced in the late harvest period, and the absorption of phosphorus during the final period accounts for approximately 15%. Too much amount of nitrogen fertilizer during the growth period of tomato not only makes the plants susceptible to planting and flowering, but also affects the absorption of calcium by the root system, causing diseases such as umbilical rot and many physiological disorders.

Second, the tomato needs fertilizer points

Basal-Autumn-Winter Tomato planting in mid-September, wintering tomato planting in mid-late-November-November, planting with organic fertilizer in combination with ploughing, spreading “Hongjie” vegetable special fertilizer 70-100/mu fertilizer - After the first fruit is done, the top dressing is started. After each fruit set, the fertilizer is top-dressed with watering once. The "Hongjie" brand vegetable special fertilizer is used for 20-35 kg/mu.
