Greenhouse No. 21 grows okra, which is the least common of the six vegetables that Liu Wei has cultivated.

The two-spotted leaf mite is a very common insect infestation and generally does not form on the scale of the infestation.

The first time Liu Wei arrived at the No. 21 greenhouse, he realized that this matter must not be as simple as insect infestation.

The okra leaves had already curled and discolored, and the cobweb-like "white film" on the north side of the leaves told Liu Wei that the okra was not fully ripe.

The appearance of a spider-like white film on the back of the leaves indicates that the two-spotted leaf mite has reached the level of insect infestation, and even if it is sprayed with pesticides, it is difficult to turn things around, not to mention that Liu Wei will definitely not use pesticides.

He immediately asked Lao Zhang to buckle the greenhouse, enclose the space, prevent the spread of pests, and at the same time check whether the vegetables in the adjacent greenhouses have been infected with pests.

The muscles on Lao Zhang's face trembled, his voice changed in an instant, and he looked at it with a bitter face and muttered:

"What's going on? How so? It shouldn't be! ”

Liu Wei stretched out his hand and patted Lao Zhang's shoulder and said:

"Don't worry, I don't blame you for this, you can take someone to other greenhouses to check first, and I'll leave it to me here."

Lao Zhang looked guilty, opened his mouth for a long time, and couldn't say a word, so he turned around and left dejectedly.

Feng Ting stood behind Liu Wei, hesitated for a while, but still spoke:

"Mr. Liu, do you want to invite someone from the agricultural technology department to take a look?"

Liu Wei smiled faintly:

"No, I can handle it myself, you can go back first."

Feng Ting wanted to say something, but Liu Wei had already stepped into the vegetable field.

The soil is okay and the nutrients are sufficient; The temperature of sunlight is naturally no problem; The only problem is irrigation water.

The reason why there is a significant gap between the quality of the vegetables grown here and other similar vegetables is that the fertilizers used by Liu Wei are the root causes.

He added those fertilizers to the irrigation water, which would improve the quality of the soil while providing plant growth, and over time, the soil would be completely changed, and even if Liu Wei completely left the earth one day, the quality of the plants growing in these soils would be much higher than now.

But now Liu Wei has no way to explain these to others, especially "peers".

It stands to reason that there is absolutely no possibility of pests and diseases in the vegetables here.

The fertilizer that Liu Wei added to the irrigation water was mainly the spiritual energy and some diluted soil essence components, as well as the stems and leaves of hundreds of mature spiritual plants, including the rhizome that had reached the mother body of the three-star wind jade valley.

The roots, stems, and leaves of these spirit plants are useless after picking the fruits, and if they are buried in the soil in the millet and clumsy space, not only will they not become nutrients for the growth of the next batch of spirit plants, but they may also reduce the grade of the soil.

After all, the soil grade in the space of those two little guys is much higher than that on Earth, and it is not the same at all.

However, if the roots, stems, and leaves of these spiritual plants, which can only be regarded as garbage in millet and clumsy space, are mixed into the soil of the earth, the quality of these soils can be improved by at least five times.

Moreover, those spiritual plants are all carefully processed fertilizers by Liu Wei by fusing spiritual energy and diluted part of the soil essence, which can effectively prevent pests and diseases.

The situation in the 21st greenhouse is obviously deliberate.

As for the reason, there is no need to think about it at all.

Liu Wei's current planting scale is expanding, not to mention, is gradually monopolizing the market, which undoubtedly smashes many people's jobs.

In this case, those people naturally can't give up easily, and it's already a relatively mild way to get some of this kind of "show".

Although these okra heels must not be allowed to enter the market again, these two-spotted leaf mites must be completely eliminated, otherwise it is easy to spread.

Just when Liu Wei was about to try his strength after being promoted to the second star, the lark in his sleeve suddenly came out and "stood" in his hand, waiting for a pair of small eyes to look at him excitedly, and the row of soft feet under his belly shook vigorously.

Liu Wei couldn't clearly feel what it was trying to express, and asked suspiciously:

"You want to try?"

The lark immediately nodded again and again, twisted around, and rose into the air, its head lit up with a little dark green light, and then quickly spread to the entire greenhouse.

In just a blink of an eye, it turned pale black, and then quickly shrunk, and was swallowed by the lark.

Liu Wei stared at the round caterpillar in surprise, his mouth wide open, and his face was incredulous.

Gu Nanquan once said when he gave the lark insect to Liu Wei before, this little thing feeds on poison, could it be that these vegetable pests are also a kind of "poison"?

Seeing Liu Wei's expression, the lark shook his head very humanely, seemed to be very proud, and even opened his small mouth to burp before twisting his body, flashing back into Liu Wei's hand, and getting into it through the cuffs.

When Liu Wei looked at those okra again, he found that although they did not immediately return to health, and the leaves were still a little curled and discolored, those two-spotted leaf mites had completely disappeared.

Feng Ting did not leave immediately after leaving the No. 21 greenhouse, but went to several surrounding greenhouses one by one.

After coming out, she planned to go to Liu Wei to make some suggestions, because she felt that although the scale and automation level of the greenhouse were very high, the management model was obviously insufficient, so it was easy for people with intentions to find loopholes and wait for opportunities to destroy.

Although Feng Ting has little social experience, her eyes are no less than those old fritters, and she naturally knows that the road taken by the company now will inevitably cause strong jealousy from her peers.

There is nothing that cannot be done when people are in the heat of jealousy.

There are so many greenhouses without accidents, but there are so serious pests and diseases in the 21st greenhouse, and it is obviously formed in a very short period of time, how can there be such a coincidence?

Besides, so many technicians here, are they all eating dry food? Why wasn't it detected early?

Thinking so, Feng Ting returned to the No. 21 greenhouse.

As soon as one foot stepped in, Feng Ting was stunned.

Although there was no obvious change in the appearance of those okras, Feng Ting still clearly felt their changes, and even felt their joyful emotions.

Seeing Feng Ting walk in, Liu Wei immediately greeted him and said with a smile:

"Didn't you go first? Why did you come back? ”

Feng Ting looked at Liu Wei in a daze, and asked with wide eyes:

"This is what you did? How did you do that? ”

Liu Wei pretended to be puzzled and shook his head:

"What did I do? How come I can't understand what you're saying? ”

If Feng Ting knew the truth, she would definitely praise Liu Wei's acting skills; But now, she could only look at him a few times in disbelief.

After all, she didn't see what Liu Wei did with her own eyes, and she didn't want to believe in her heart that she had met a "super" boss......
