High-yield cultivation techniques of Tomato in greenhouse

First, establish a high standard warm greenhouse in winter.

Tomato overwintering production temperature is the key factor. In order to provide necessary temperature conditions for tomato growth, it is necessary to establish a high-standard winter greenhouse with good heat preservation and fast heating.

Second, choose the best sowing date

Arranging a large number of tomatoes to be put on the market before the Spring Festival will get the highest economic benefits. The sowing date of this kind of tomato can be chosen from mid-late August to early September.

III. Selective fertilization

The types of fertilizers needed in different growth processes of tomatoes are different. for example, potassium fertilizer should be used before tomato green fruit changes color, and water-soluble fertilizer can be selected in the later stage.

Fourth, cultivate roots and protect leaves

The yield of tomato is directly related to the development of its root system, so after the completion of planting, fertilizer and water must be irrigated in about a week to make the roots of tomato seedlings deeply rooted.

Whether the leaves are healthy or not will affect the normal growth of tomato plants. If the leaves are not properly maintained, it is easy to cause premature senescence, resulting in low yield. Specific methods can refer to spraying appropriate warm water or sugar water in cloudy and foggy weather to increase foliar humidity.
