In order to taste the taste of these vegetables, Zeng Zhi cut two lettuce shoots on the spot and went home, planning to fry meat at night.

However, when peeling the lettuce, looking at the tender lettuce, Zeng Zhi cut it directly at the top, and after peeling it, he ate it directly.

The taste is very good, crunchy, and there is a faint sweetness, although this taste, although it is worse than the lettuce produced in the Qinglian Secret Realm, but it is much better than the ordinary lettuce on the market, and even, compared to the lettuce grown at home in the past few years, the taste is better.

Although the lettuce grown by his own family in recent years has been grown with farm fertilizer, the use of chemical fertilizers has not been completely eliminated. When Cui Miao was around, he inevitably used some urea or something.

And the taste of lettuce watered with the spiritual spring water of the secret realm reminded Zeng Zhi of the taste of lettuce grown at home when he was only a few years old. At that time, it was still around 90, and the family did not use chemical fertilizers to grow vegetables at all.

Not to mention growing vegetables, at that time, crops such as rice, corn and potatoes were grown in the fields, and only a small amount of phosphate fertilizer and urea were used. After all, the economy was still very underdeveloped at that time, and chemical fertilizers were scarce and expensive, and farmers in this mountainous area basically could not afford to use chemical fertilizers for farming. Therefore, farmyard manure is mainly used.

Zeng Zhi still remembers that at that time, every morning, his parents had to get up early to cut the grass and go home to feed the cattle and pigs, in addition to using the labor of the cattle and the economic income from the sale of pork, another important purpose was to use pig manure and cow dung to farm, which is the main source of fertilizer in the field.

At that time, all the fields and ridges were cleaned up at any time, and there were no weeds or weeds at all. It's not like now, when you apply herbicides three or four times a year, and the result is still full of weeds.

It is precisely because of the fact that there was no chemical fertilizer at all to grow vegetables at that time, so the lettuce and tomatoes grown at home tasted very good. As for the tomatoes, they are also picked directly, and they are eaten without even washing. At that time, I didn't use any pesticides, so it was safe to eat.

However, with the spread of chemical fertilizers and pesticides, although the yield of vegetables has increased considerably, the taste has slowly changed.

And the lettuce that was cut home today, because it has just entered April, the parents have not even used chemical fertilizer to promote the seedlings, but they were watered once by Zeng Zhi with spiritual spring water, and the result grew too fast and entered the maturity period in advance. This makes these lettuce not "destroyed" by chemical fertilizers, and the aura in the spiritual spring water tastes very good.

Zeng Zhi was very satisfied with this result, because it meant that his idea of developing a vegetable base in his hometown was feasible. The only thing that needs to be done now is to experiment with how to use the spring water to make the vegetables grow normally and at the same time ensure their taste.

After all, with pure spiritual spring water, even if Zeng Zhi had deliberately controlled the dosage, the growth of the vegetables in the vegetable field was still a bit shocking.

………………

In the next few days, Zeng Zhi was distracted and continued to deliver food to the eldest sister's restaurant and Wang Yan in the morning, and after these two things were completed, he went to apply for an industrial and commercial business license, and at the same time paid attention to the progress of the store's decoration, and in the afternoon, he drove home to continue his experiment.

Zeng Zhi's goal is to be able to cultivate delicious green ingredients on a large scale without exposing the secret realm of Qinglian, how to save time and effort, and how to do the most things in the simplest way, are all things that Zeng Zhi needs to consider.

Zeng Zhi used the secret realm spiritual spring water and ordinary spring water, mixed them according to different proportions, and then watered the vegetables, so as to judge what proportion of the secret realm spiritual spring water could not only cultivate delicious vegetables, but also not too shocking.

In addition, Zeng Zhi also used different proportions of secret realm spiritual spring water to test the impact of secret realm spiritual spring water on the later growth and development of vegetables after soaking.

Through this incident, the comparative experiment that Zeng Zhi learned in his high school biology course had a practical experiment ten years later.

However, because the previous lettuce was urged too hard by him, it suddenly became a mature product and could be eaten directly, so he did not use lettuce as an experimental object, but a kind of vegetable - tomatoes.

The reason why tomatoes are chosen is because they are widely used in Chinese cuisine, whether it is cold salad, soup, stir-fry, it can be seen; Tomatoes can even be eaten as a fruit. In addition, tomatoes are produced in high yields and are easy to store and transport, making them a prerequisite for large-scale production.

If the tomato planting experiment is successful, Zeng Zhi will naturally launch new varieties.

Everything is difficult at the beginning, as long as you find out the rules, it will be simple to draw a scoop according to the gourd in the end.

Of course, Zeng Zhi chose tomatoes as the experimental object for another reason, that is, many tomato seedlings have been cultivated at home, and after the first watering, these tomato seedlings are already a ruler high, and they will soon bloom and bear fruit after transplanting.

This has undoubtedly reduced the cultivation time quite a bit.

………………

While experimenting in the outside world, Zeng Zhi also cultivated land in the Qinglian Secret Realm. Not only did he introduce a lot of vegetables that were common in the market but not found in the Qinglian Secret Realm, but he also introduced a lot of fruit tree seedlings, and his carry-on orchard plan basically completed the first step.

Just as vegetables grow rapidly in the Qinglian Secret Realm, these fruit tree seedlings grow at the same fast rate after being introduced into the Qinglian Secret Realm. Of course, it is not like the vegetables and fruits that were originally planted inside, and the ripe fruits will bear fruit within a few seconds after planting.

Zeng Zhi did not delve into why the varieties he introduced were not like the original varieties in this area, which could grow new products immediately after picking. However, he also had some guesses, this should be related to himself now being just a rookie in cultivation who had just entered the first level of Qi cultivation, and he did not have the unpredictable means of his cheap master, and it was naturally impossible to get the level of his cheap master for the use of the Qinglian Secret Realm.

In general, although it was only three or four days, the first batch of fruit tree seedlings planted by Zeng Zhi in the Qinglian Secret Realm began to sprout new sprouts after turning green, and the entire fruit forest began to show a lush appearance, which made Zeng Zhi look forward to the future space fruits.

Since the vegetables watered by the spiritual spring water of the secret realm are so delicious, the fruits planted in the secret territory of Qinglian should not taste bad!
