How to grow and manage tomatoes for high yields

Tomato is a multi-harvest crop with a long growth cycle and high yield, but it also requires more nutrients.

Among them, the three major elements of nitrogen, phosphorus and potassium are indispensable, and corresponding trace elements must also be supplemented . The time and method of fertilizing tomatoes affect the growth rate and fruit quality of tomatoes. Several principles should be mastered when fertilizing.

1. Apply base fertilizer heavily

We all know that tomatoes have a relatively large demand for fertilizer, so the amount of base fertilizer used is also relatively large. Generally, 2500-3000 kg of base fertilizer is applied per acre of land.

The base fertilizer is mainly composed of decomposed high-quality organic fertilizer, and can be used together with superphosphate, potassium sulfate, etc.

It should be noted that tomatoes do not have a large demand for phosphorus, so when applying base fertilizer, pay attention to the content and composition of the fertilizer.

Before applying fertilizer, land preparation should be done well, the soil should be deeply plowed, and the organic fertilizer and soil should be fully and evenly mixed to provide a loose, high-quality and healthy soil environment for the growth of tomatoes.

2.Apply appropriate amount of topdressing

Tomatoes need continuous topdressing during the growth process, and the water-soluble fertilizers selected will vary depending on the time of topdressing.

For example, before the first time, you can apply a balanced macronutrient water-soluble fertilizer , and when the fruit is expanding for the second time, you can apply high nitrogen fertilizer. During the topdressing process, you can use high nitrogen and organic fertilizers to avoid premature aging of tomatoes.

During the topdressing process, it is necessary to monitor the soil conditions of tomatoes in real time. If the soil lacks potassium, cracked fruits, deformed fruits, etc. will occur.

During the entire growth process of tomatoes, the demand for nitrogen, phosphorus, potassium, calcium, and magnesium accounts for 100:26:180:74:18 respectively, so don't just focus on the supplementation of the three major elements.

3. Apply foliar fertilizer skillfully

Nitrogen, phosphorus and potassium provide most of the nutrients for tomato growth, but tomatoes still need other nutrients during their growth, such as calcium, magnesium, boron, etc.

The content of these trace elements is not high, but they are very important. For example, calcium can reduce fruit drop, and boron can prevent deformed fruit.

The spraying of foliar fertilizer should be done at the right time. During the seedling stage, flowering stage, fruit setting stage and fruit swelling stage, it is necessary to spray foliar fertilizer at the same time as fertilization to achieve the ultimate goal of increasing production, improving quality and enhancing economic benefits.

Generally speaking, the process of topdressing tomatoes should be carried out according to the plan of "one control, two promotions, three sprays, and four taboos".

The first control is to control the amount of topdressing from planting to fruit setting.

The second stage of promoting flowering and fruiting is to increase the amount of topdressing.

Three sprays are to spray foliar fertilizer 2-3 times during the fruit development period.

The four taboos are avoid fertilizing at high temperatures, avoid concentrated fertilization, avoid fertilizing at high temperatures, and avoid fertilizing at high humidity.
