China is the country with the largest tomato cultivation area and the largest total production in the world. Tomato, also known as tomato, is native to South America. It was introduced into China in the Ming Dynasty and gradually became one of the favorite foods. The annual output is over 50 million tons, and it is growing. The main tomato producing areas in China are mainly Xinjiang, Inner Mongolia, Hebei, Shandong, Henan, Jiangsu and other provinces.

At present, tomato has developed into one of the most important vegetable varieties in China. In 2015, the output of tomato was 55.94 million tons, accounting for 7.1% of the total vegetable output in China. In 2016, the area planted with tomato increased slightly, the output increased steadily; the consumption demand increased slightly, and the consumption structure became more rational; in terms of international trade, exports declined steadily, and processing exports declined more significantly;

The annual average wholesale price dropped first and then rose, generally showing a "U" type distribution. The planting area of ​​tomato open land will be reduced, the planting area of ​​the plant is expected to expand; the demand for consumption is steadily increasing, the variety of consumption is more abundant, and the diversification of consumption products; the export of processed products may continue to decline; the price will be slightly lower, and the fluctuation range will be less than that of the previous year. The same period.

Tomatoes are one of the common vegetables. The fruit is rich in nutrients and has a special flavor. What is the fertilization and irrigation technology of tomatoes? Today we will learn about the technology of fertilizing tomatoes.

Tomatoes need fertilizer characteristics

The ratio of tomatoes to NPK is 1:0.2:1.7. Tomatoes prefer fertile soil. Before the fruit is placed, the demand for nitrogen fertilizer is large. After the fruit setting, the demand for nitrogen fertilizer drops sharply. The demand for potassium fertilizer Soaring. According to this physiological characteristic of tomato, in fertilization, it is necessary to pay attention to the timely supply of fertilizer at different stages of growth and development in order to reduce the physiological deficiency of tomatoes caused by unreasonable fertilization.

Base fertilizer application

Before the tomato is planted, it is necessary to apply sufficient decomposed organic fertilizer for nutrient supply during the whole growth period, and the application of organic fertilizer is beneficial to improve the soil, increase the agglomerate structure of the soil, improve the permeability of the soil, and create a good growth for the root system. Develop environmental conditions, promote strong roots and strong seedlings, and increase plant resistance.

Timely topdressing

Tomatoes are generally not topdressed after planting until they are placed. When the first group of fruits begins to expand, the topdressing is combined with topdressing. Later, during the second and third groups of fruit expansion, the application amount of potassium fertilizer should be increased to make the plants grow well. And with the use of biological bacterial fertilizer, in order to promote the growth of roots, control the occurrence of harmful bacteria, prevent root diseases and premature aging, improve yield and quality.

Reasonable spray fertilizer

The rational use of foliar fertilizer can solve many problems. It can play a role of top dressing. The physiological diseases caused by plant deficiency can be supplemented by spraying foliar fertilizer.

For example: foliar spray 1500 times speed boron or 400 times borax, can effectively prevent the phenomenon of cracking and improve the quality of flower bud differentiation; foliar spray 600 times nucleotide foliar fertilizer plus 2000 times zinc sulfate, can effectively prevent the heart of tomatoes Yellowing, and can enhance the resistance of tomatoes; in the middle and late growth stages of tomatoes, spraying 400 times cytokinin with 300 times of potassium dihydrogen phosphate can prevent premature senescence of plants and significantly improve the yield and quality in the later stage.

Protective Goggles

It can prevent some medicine or blood from splashing on the face, thus protecting the eyes. This kind of glasses is generally used in conjunction with masks and surgical caps to fully protect the doctor's head.
[Functions of medical eye masks]
1. Prevent blood, potion and other liquids that cause damage to the skin from causing unpredictable damage to the eyes.
2. It can prevent the impact of objects on the eyes during close surgery.
3. The inner space of the eye mask is large enough for doctors who wear myopia glasses.

4. The breathability must be good, generally there are vents
