The fermentation time is about 40 days. After the fermentation is completed, directly It’s okay to spread the field evenly.
Because chicken manure is used in a large amount, if it is not decomposed, it is easy to cause pre-burning phenomenon. Therefore, farmers are not recommended to use dry chicken manure directly, and must be fully decomposed before use.
It is recommended that farmers should not use human excrement to supplement organic fertilizers, because the amount of use does not work. If the amount of use is large, the tomatoes are mostly in a high temperature environment, and the use of these people's excrement is prone to tomato pathogens, and Causes great damage to the roots of tomatoes.

Phosphate fertilizer: Phosphorus is used as the base fertilizer. It is recommended that all the phosphorus elements required for tomato in the whole growth period are used as the base fertilizer. 200 mu of superphosphate can be used in one mu of land.
Potassium fertilizer: The amount of potassium fertilizer used as the base fertilizer should account for 20% of the total amount of tomato required for the whole growth period, and 80 kg of potassium sulfate can be used for one mu of land. Farmers must pay attention to the use of potassium sulphate when using potassium chloride, otherwise it will lead to a decline in the taste and commerciality of the tomato.
3. Use of medium and trace element fertilizer
Many farmers in the choice of base fertilizer, it is easy to ignore the use of trace elements, such as calcium fertilizer and boron fertilizer, zinc fertilizer. In particular, calcium fertilizer plays a key role in tomato yield and disease prevention, and tomato demand for calcium fertilizer is second only to potash.
Commonly used method: use medium and trace element mixed fertilizer, use 2 kg of acre of land, and plow the land after fertilizer application. It is recommended that farmers use a rotary tiller that can be turned over 25 cm or more in order to facilitate the development of tomato roots and fertilizer. Use.
