Talking about ketchup

Tomatoes are getting worse and worse now. When I think of it, the tomatoes before were all shiny and watery, and they tasted sweet and sour. They are very delicious. Do you remember scrambled eggs with tomatoes when you were a child? They are very delicious, and you like them very much, but tomatoes are not as delicious as before.

I usually choose "Zhongza 9", which is not only strong in disease resistance, but also has large fruit and sufficient water. Choose varieties with strong disease resistance, mainly because raw tomatoes are not sprayed with pesticides.

The tomatoes planted now are all fine varieties, and the key is to pay attention to the yield. Besides, some tomatoes grown in Da Peng are not in perfect season, so they taste bad. In particular, there is a medicine called ripening agent, which only needs to be sprayed the night before. Whether it is ripe or not, tomatoes will turn red the next morning. This ripening agent is sour and astringent.

The roots of tomatoes are relatively developed, so as long as the soil is acidic and loose, the requirements for the soil are not high. At the same time, we should plant eggplant in turn, that is, we should not plant eggplant vegetables continuously. Eggplant vegetables include peppers, tomatoes and eggplant.

Before planting, you must turn over the soil, at least to the depth of the hoe, because tomatoes have developed roots and deep soil layers. If the pole is thick and the foundation is unstable, it is easy to break. In addition, it is best to build the ground into strips, which is beneficial to water irrigation. In addition, tomatoes with pH6.5 are most suitable for the left and right soils. If it is planted on a large scale, it is best to carry out land testing.

If the external environment temperature is too high, the growth potential of tomato seedlings will be weak, which will "burn" the seedlings and affect their normal growth. Of course, too low temperature is not good, and too low temperature will also have an adverse effect on the growth of seedlings. The daytime temperature is generally controlled at 25℃, and the nighttime temperature is generally not lower than 20℃, preferably above 25℃.

Before tomato seedlings are raised, base fertilizer should be prepared. It is suggested to use enough nitrogen, phosphorus and potassium fertilizer, in which the amount of nitrogen fertilizer is greater than that of phosphorus and potassium fertilizer, because nitrogen fertilizer can promote plant growth before flower bud differentiation and play a vital role. In addition to nitrogen, phosphorus and potassium, mature organic fertilizers should be used to provide trace elements such as calcium, magnesium, zinc, boron and iron for its growth, so as to ensure the rapid growth of tomato seedlings in the early stage and lay a solid foundation for flower bud differentiation, pollination, fruit setting, expansion and coloring in the later stage.
