| Write NO MORE THAN THREE WORDS for each answer. Tomatoes are the world's most popular fruit rich in nutrition like Vitamin A, C, fibre and lycopene (番茄红素). Researchers have found that consuming lycopene helps in preventing cancer. Tomato also helps in keeping the skin healthy and young by protecting from harmful rays. Since lycopene is present in the cellular wall of tomato, it is better to consume cooked tomato to have higher concentration of lycopene. So tomatoes are a wonderful fruit. Then how to grow tomatoes? First, there should be regular and even watering in the fields where tomatoes grow. You can also add fertilizer to have better results. Plant the tomato plants with enough space(for example 2 to 3 inch space)between each other to lessen spreading of disease and pests and help the fruits get enough sunlight. Provide support like pole when the plants grow up to prevent from disease and to increase the crop product. In order to make your tomatoes grow well, you should take some useful tips. For example, choose variety based on the season and soil type that you are growing. Planting site should have enough sunlight to have more fruits. Prune(修剪)the tomato plants if necessary to maintain a manageable size. Check tomato plants regularly for any kind of pests and diseases. To people's regret, tomatoes possibly suffer from some diseases during their growth. So you must try your best to prevent them. Soil should be free from debris(残骸)of earlier plant remains and should be treated first before tomato plantation like solarizing(晒) to prevent from pests. It is always better to choose resistant plant varieties and follow crop rotation(轮作)as far as possible.
