1.2-4 weeks after transplanting：Drip irrigation  15-30-15+TE 3-5Kg/666㎡，7-15day/time，total twice. Drip irrigation: Seaweed Amino acid  1-3Kg/666㎡，total once.  

2.The first spike flower appears：Foliage spray:   EDTA-TE（Flower and fruit） 800-1000 times，7-15 days/time，total 3 times

3.begin to set fruit：Drip irrigation: Fish protein  3-6kg/666㎡，7-15 days /time,continuous use

4.Fruit expansion stage:  Drip irrigation:15-15-30+TE  alternate use 3-5Kg/666㎡，7-15 days/time.

Foliage spray : EDTA-TE（Balance）Use once after each pick，1000-1500times.

5.Color transition and maturation:  Drip irrigation: 12-6-42+TE alternate use 3-5Kg/666㎡，7-15 days/time.

Foliage spray : CA Mg Fertilizer 800-1000 times，7-10days/time，continuous use.

0-160-500+TE：If the tomato has uneven coloring, light color and other coloring problems, it can be sprayed on the leaf surface to promote color

transformation.
Seaweed amino acid：it can enhance the seedling and strengthen the root in the seedling stage ; it can improve the fruit quality in the fruiting stage;

and avoid using at the flowering stage.
Humic acid fertilizer：If the soil of tomato planting has salinization, compaction, and poor water and fertilizer retention ability, it can effectively

improve the soil environment and replace a large number of other elemental fertilizers.

Note
1. The amount, frequency and type of topdressing should be changed according to the actual situation.
2. Excessive application of nitrogen fertilizer should not affect yield and quality in flowering and fruiting period.
3. Use the same equipment to apply a variety of fertilizers after cleaning or pouring water to clean the pipeline to avoid the reaction

of a variety of fertilizers resulting in precipitation blocking the pipeline.

Growth habit of tomato

Tomato is an herb in the nightshade family, including limited growth, semi-limited growth and infinite growth.It can grow for many years when conditions are suitable. Tomato is a temperature-loving, heat-less, light-loving, short-day plant that can tolerate drought but not waterlogging.Tomatoes love water, leafy stems in the upper part of the plant, transpiration is fast.Tomato roots developed, strong water absorption, can not be short of water during the growth period, soil moisture should be 60%~80%, air humidity should be 45%~50%, air humidity is large, not only hinder normal pollination, but also in high temperature and high humidity conditions serious disease. 

Tomato has strong adaptability, and the soil conditions are not very strict, and the soil pH6~7 is appropriate.Sufficient light can promote the accumulation and conversion of nutrients, transporting sufficient nutrients for plant growth, making the plant strong resistance.It can prevent barren growth and improve the yield. 

Tomatoes like fertilizer, the amount of fertilizer is large, and the nutrients required in different growth periods are also different.It is suitable for planting in fields with fertile soil, deep soil layer, loose soil, sufficient light, convenient drainage and irrigation, no pests or low incidence of pests and diseases, away from pollution and clean water. 

Tomato fertilization rule
 According to research, the production of 1000kg tomato requires nitrogen 2.0~3.5kg, phosphorus 0.60~1.0kg, potassium 3.6~5.3kg. In tomato production process, the demand of nitrogen in the early stage is the highest, the demand of potassium in the late stage is more, and phosphate fertilizer should be applied evenly in the whole growth period.It also need to absorb a variety of trace elements, such as calcium, boron, manganese, zinc and so on.

The root activity reached the highest from flowering stage to fruiting stage, and the fertilizer absorption ability of tomato root decreased after entering the full fruiting stage.  Tomato calcium content is high, so the need for frequent supply, calcium deficiency is easy to lead to physiological obstruction and fruit umbilical rot.The balanced supply of phosphorus fertilizer should be used to promote the differentiation of flower buds during the continuous flowering process.
