Key Points and Precautions for Tomato Fertilization Techniques

Tomato, also known as xihongshi, can be eaten as a vegetable and also as a fresh fruit. It is deeply loved by consumers around the world, and market demand is large. Today let us learn about the key points of tomato fertilization techniques.

1. Apply sufficient base fertilizer. The base fertilizer should mainly be decomposed high-quality organic fertilizer at 2-5 t/mu, and according to differences in tomato variety maturity, planting stage, etc., it should be paired with an appropriate amount of organic fertilizer. For early-maturing varieties, apply phosphate fertilizer at 25-30 kg/mu, potassium sulfate at 35-40 kg/mu, and additionally increase urea at 15 kg/mu. Apply zinc sulfate at 1 kg/mu; apply borax at 0.25 kg/mu; apply 3% phoxim powder at 3-5 kg/mu.

2. Reasonable topdressing. 2.1 First topdressing: 10-15 d after tomato transplanting, to promote early seedling growth and development, vegetable special fertilizer (Lefu Genhao barrel fertilizer) at 8-10 kg/mu should be applied with irrigation, or by drenching roots with a 300-fold dilution, which can promote root growth and development (well-developed roots, many new fibrous roots), raise seedlings, and resist root rot. 2.2 Second topdressing: before flower bud differentiation, apply Lefu Fei Jingling series (high phosphorus) at 4 kg/mu, which can be used together with nanotechnology series (Nano B) diluted 600-fold for spraying, to promote flower bud differentiation, preserve flowers and fruit, and increase fruit set rate. 2.3 Third topdressing: when the first cluster of fruit begins to swell, apply Lefu barrel fertilizer (Guohao) at 10 kg/mu, paired with high-potassium fertilizer Jingling at 4 kg/mu, for the best effect. It can achieve fruit enlargement, high yield, and improved stress resistance.

2.4 Fourth topdressing: when the first cluster of fruit is near harvest and the second and third clusters of fruit are swelling, the main plant enters the peak fruiting period. Apply Lefu Chongfeng barrel fertilizer at 10 kg/mu by irrigation, paired with 4 kg high-potassium fertilizer Jingling. Afterward, according to the main plant's growth trend and the soil's fertilizer supply, high-potassium fertilizer Jingling can be applied 1 to 2 more times (each time 4-6 kg/mu), which can both promote fruit retention and extend the fruiting period, and prevent premature aging and yield reduction. Irrigation and topdressing, with appropriate hilling and soil cultivation, can promote tomato root growth and development. When the soil is deficient in potassium, topdressing potassium fertilizer in the later stage plays an important role in making tomato fruit color evenly, reducing deformed fruit, and improving fresh fruit quality.
3. Application of foliar fertilizer. About half a month after seedling emergence and transplanting, spray Lefu 205 and foliar fertilizer at 20 ml/barrel; at the early stage of flower bud differentiation, spray the same amount as above, plus Lefu Nano Boron at 25 ml/barrel; spray once during the full production period (in the later stage of tomato growth, when leaf and stem growth begins to slow, in order to strive for later yield and prevent premature aging), with the same method and dosage. In summary, the above are the key points of tomato fertilization techniques. Growers and friends are welcome to continue adding knowledge. Fertilization is a very important stage in the entire crop planting process and must be well mastered.
