Planting tomatoes is a good way to make farmers rich, and strengthening the management of tomato growth period is the key to obtain high efficiency and production.

 1. Pay special attention to the growth period management. The main measures are hoe weeding, water storage, shelf and tendril set-up, training pruning, leaves removing and ventilation & light obtaining. Prevention and control of plant diseases & insect pests and the temperature management are also extremely vital. The main diseases of tomato are virus disease, bacterial wilt, and disease early and late blight, etc; Pests are mainly cotton bollworm, aphid disease, etc. The diseases of tomato can be prevented, but is hard to cure, so that diseases prevention should be taken into priority. The methods of virus disease prevention and control are seed varieties selecting, seeds disinfection, crop land repeatedly using for the same variety, prevention and control of aphids, early engraftment in optimum period, etc. Temperature management is rather important. Daytime temperature should keep around 25 ℃ by strengthening the ventilation of plastic houses and night temperature should keep between 10 -13 ℃. Ventilation hole should be kept from small to large to make the wind go through from less to more, in the afternoon when the temperature drops, the ventilation hole should be kept smaller gradually or shut down.
2. Pay special attention to watering management. Tomatoes growing in summer and the rainy season usually don't need to water, but when the 2nd - 3rd ear fruits ripen in drought, appropriate watering is necessary. According to tomato plant growth situation, appropriate fertilization is necessary so as to promote the fruit growth. Tomatoes fertilized with bacterial manure can be much more better in many aspects such as color, sweetness and output than those without it. Gymboree microbial fertilizer is good for base fertilizer and the fertilizer Campbell Gen Miaozhuang or Miaojianzhuang is fit for top application. Spraying Golden treasure sweet spirit will make fruits look more beautiful. When greenhouse nutrient deficiency is relatively serious, spraying golden treasure tonic spirit (growth increasing spirit) can efficiently solve the problem. 

3. Timely pick fruits. The 4 ripening periods of tomatoes are green ripe, discoloration, mature, and full ripeness. Fruits can be harvested in the green ripe stage for storage preservation. For transportation, fruits can be picked in discoloration period (a third fruit are red). For the sale or self-food providing, the harvest should be in the mature period (more than a third fruit are red). During the harvest, fruits should be treated gently and fruit stalks should not be picked with fruits to avoid wound. In fruit ripening period, it is unfavorable to use hormone stimulation for fruit coloring and fruits should be selected carefully before packing for sale. Its advantage is to reduce the production cost, improve fruit quality, and ensure the food safety of consumers.
