What is the difference between soilless tomatoes and tomatoes in general

There is no difference, it's just that the cultivation method is different. Soilless cultivation is a new technology for crop cultivation that has been developed in recent decades. Crops are not cultivated in the soil, but in an aqueous solution (nutrient solution) in which minerals are dissolved.

Village; Or in a certain cultivation medium, the crop is cultivated with a nutrient solution. As long as there is a certain amount of cultivation equipment and certain management measures, crops can grow normally and obtain high yields.

Soilless cultivation is free from the limitations of the soil, which greatly expands the space for agricultural production, so that crops can be produced on barren land, and the development prospects are very extensive. Almost all plant factories use a soilless cultivation model.

Advantages of soilless culture;

1. Water saving, fertilizer saving, high yield: various nutrients required by crops in soilless cultivation are artificially prepared into nutrient solution for application, with less water loss, balanced nutrients, high absorption efficiency, and scientifically advanced nutrients according to crop types and different growth stages of the same crop. Therefore, the crop grows robustly and vigorously, and can give full play to the potential for increasing yield.

2. Clean, hygienic and pollution-free: soil cultivation and application of organic fertilizer, fertilizer decomposition and fermentation, resulting in odor and pollution of the environment, will also make the eggs of many pests breed, harm crops, and soilless cultivation is applied with inorganic fertilizer, there are no these problems, and can avoid the pollution of heavy metals and other harmful substances in the polluted soil.

3. Labor-saving, labor-saving, easy to manage: soilless cultivation does not require cultivating, ploughing, hoeing and other operations, which is labor-saving and labor-saving. Watering and topdressing are solved at the same time, and are regularly and quantitatively supplied by the liquid supply system, which is convenient to manage, will not cause waste, and greatly reduces labor intensity.

4. It is conducive to the realization of agricultural modernization.

Soilless cultivation frees agricultural production from the natural environment.

It can be produced according to human will, so it is a controlled agricultural mode of production.

To a large extent, farming according to quantitative indicators is conducive to the realization of mechanization and automation, so as to gradually move towards an industrialized mode of production.

In fact, there is no difference in the method of planting, of course, the price is also different, the soilless is expensive, and it is recommended to eat the general. Soilless is like platinum, and compared with **, it is just a refining method, and the nutrition of soilless tomatoes is not as good as that of tomatoes grown in soil.

Tomatoes, also known as tomatoes and persimmons. The ancient name is June persimmon, good news three yuan. In Peru and Mexico, it was originally called "wolf peach".

The whole body is viscous glandular hairs with a strong odor. The stems are prone to lodging. Leaves pinnately compound or pinnate deeply lobed, leaflets very irregular, unequal in size, ovate or rectangular, margins irregularly serrated or lobed.

calyx radiate, lobes lanceolate, fruiting; The corolla is radiate, yellow. berries oblate or nearly globular, fleshy and juicy, orange or bright red, smooth; Seeds yellow. Flowering and fruiting period: summer and autumn.

Tomato is a temperature-loving and light-loving vegetable, and the requirements for soil conditions are not too strict, but in order to obtain a high yield and promote the good development of the root system, a fertile loam soil with deep soil layer, good drainage and rich in organic matter should be selected. Native to South America, it is widely cultivated in the north and south of China.

Tomatoes are nutritious and have a special flavor. It has the effects of eliminating fatigue, increasing appetite, improving the digestion of protein, and reducing stomach distension and food accumulation.

Soilless is delicious because soilless red pimples contain trace elements that suit the taste, and the taste has a rustling feeling.

I found that soilless tomatoes are harder and not easy to fry, that is, they are not easy to fry the juice, and I don't like to eat them; Native tomatoes are easy to fry, fried bright red juice, making soup is really colorful, flavorful, like!

(1) Variety selection There are two types of tomato cultivars: limited growth and unlimited growth. Early-maturing varieties with limited growth showed short growth period, early maturity, low total yield and high density; The infinite growth type is the late-maturing variety, which shows a long growth period, medium and late maturing, high total yield and low density.

Both types of tomato varieties can be used for soilless cultivation in different seasons. At present, tomatoes, cucumbers and other crops, there is no special variety suitable for soilless cultivation, and generally the early and late maturing varieties of tomatoes that perform well in the local area can be used for soilless cultivation production. For example, Maofen 802, L-402, Xifen 10, Zaofeng, and Zhongshu 4 all performed well.

2) Cultivation form The density of tomato and cucumber under soilless cultivation conditions is basically the same as that of cultivation form. Early-maturing varieties have a higher density of tomatoes than late-maturing varieties. Bag culture, rock wool culture, substrate trough culture, NFT and other cultivation forms are suitable for soilless cultivation and production of tomato and cucumber.

3) Cultivation season The stubble and season of tomato soilless cultivation are arranged in the same principle as that of cucumber. The following is an example of the stubble arrangement of soilless cultivation in energy-saving solar greenhouses in North China for reference.

Autumn and winter stubble: tomato is sown in mid-August, cucumber is sown in early to mid-September, and soilless seedlings such as vermiculite and grass are raised in North China. Tomatoes are planted in mid to late September, and cucumbers are planted in early October; Tomatoes bear fruit from early to mid-November to early February, and cucumbers bear fruit from late October to early February.

Winter and spring stubble: cucumbers and tomatoes are sown during January, tomatoes can be sown around New Year's Day, cucumbers are sown in early January, and small arch sheds are covered in the solar greenhouse without soil seedlings; Tomatoes and cucumbers were planted from late January to early February. Fruiting begins in March and seedlings are pulled in June.

4) Nutrient solution formula: Please refer to the relevant formulas listed above. The special tomato recipes selected by Shandong Agricultural University are listed (Table 5-7).

Table 5-7 Macro-element recipes for tomatoes.

Trace elements are added according to the trace element table listed above, and the pH of the nutrient solution is.

5) Post-planting management Conventional field management of tomato is the same as soil cultivation, and the management method of soilless cultivation is referred to the cucumber section.

It is true that the tomatoes grown by yourself do not look good, but they have a good taste and a strong tomato flavor.

The reason for the bad appearance is that the general ** tomatoes are commercial products, which are planted in greenhouses, and the environment inside is regulated according to the appropriate growth temperature of tomatoes, and there is no harsh environment like natural growth in the open field, so the tomatoes in the greenhouse will generally look better, and now the commercial tomatoes, there are many varieties, in order to pursue the appearance and yield, they are all products that have undergone various hybridization, so they look good-looking and hard. But the taste is very ordinary. This is the situation brought about by sacrificing the taste of tomatoes, so now many people say that tomatoes don't have a tomato flavor anymore.

Although the tomatoes we grow are not good-looking, the taste is really much better than what we sell outside, the reason is that the tomatoes we grow ourselves use less chemical fertilizer, and generally use organic fertilizer, because we pay more attention to the taste, and then let the tomatoes be picked when they are ripe, so that the tomatoes will have more time to accumulate nutrients and the taste will be better. Of course, it is also important to choose the varieties of tomatoes you grow, many of them are old varieties from the past, and the taste will be better.

Therefore, if you want to eat delicious tomatoes, you are still encouraged to plant them yourself, even if you don't have a garden, you can plant them on the balcony, and now it is popular in the city to be a sunshine vegetable farmer, that is, you can eat delicious and safe vegetables and have a sense of achievement, which is the best of both worlds.

If you grow tomatoes by yourself, choose a larger and deeper pot, choose good seeds, in addition to spraying some beneficial bacteria and medicines at the beginning, such as Trichoderma harzianum, the toxicity of this medicine is not strong, just spray some at the beginning, it will not affect the safety of tomatoes, prevent some diseases of tomatoes, and you can grow normally.

Tomatoes are not really plants that need to be taken care of often, as long as you put a good shelf on it, give it sunlight, and bury the bottom fertilizer, it will grow as big and plentiful as you expect, and bear a large bunch of delicious fruits.

Because the tomatoes grown by themselves are all natural fertilizers and are not managed by hormones, although the tomatoes outside are beautiful, they contain hormones more or less, and they are not healthy to eat.

I think it's normal, because they've been growing tomatoes for a long time, so they have a lot of experience.

Because the tomatoes you grow grow naturally, they don't grow with a certain mold like the tomatoes you buy.

The first is that the varieties may be different, and then the management mode, which will also occur in different environments in which tomatoes are grown.
