In the morning, Li Shuanzhu was sorting out the accounts in the house, preparing to clean them when he returned to Baozi Shop. Shitou'er and others still went to the vegetable field. Now the weeds in the field have grown so much that they need to be pulled out manually, which is also a very time-consuming task.
Hard work.
Just as Li Shuanzhu was concentrating on calculating the accounts, Shunzi suddenly ran into the yard and entered the house without knocking on the door.
Li Shuanzhu frowned and was about to scold him when Shunzi took a deep breath and said first:
"Brother Shuanzhu, there are grubworms in the ground. It's so big."
Li Shuanzhu was shocked. He hadn't seen this much yesterday, so why did it suddenly become popular?
"Is everything growing in the ground?" he asked Shunzi.
"There are no leeks in the field, but there are others. The rapeseed grows the most." Shunzi wiped the sweat from his forehead with his hand.
Leeks have a special smell that many types of pests dislike, so they are spared.
"Let's go and take a look." Li Shuanzhu put down the accounts in his hands, locked the door and left the hospital, and walked quickly to the fields with Shunzi.
When they got to the field, Li Shuanzhu asked the others not to stop their work. He and Shunzi came to the small rapeseed field that was the most severely affected. They walked closer and squatted down to take a look. As expected, many bright green rapeseeds were densely covered with gray dots.
If you look closely, it's still squirming.
Aphids, whose scientific name is aphids, belong to the family Aphididae of the order Homoptera. They are pests with piercing-sucking mouthparts. They often cluster in leaves, tender stems, flower buds, terminal buds and other parts to pierce and suck sap.
Li Shuanzhu knew that this was a common pest in the field that grew and reproduced very quickly. However, the reproduction rate this time exceeded his previous experience. But after thinking about it, he probably thought that the nutritional content of this special vegetable was quite good, which promoted the growth of the pest.
Reproduction and development.
Another feature of grubworms is that they secrete sweet honeydew, attracting ants and so on.
Measures must be taken immediately, otherwise, the vegetable leaves will curl quickly, and if the shrinkage is severe, the entire plant may even die.
"Shunzi, quickly go to the agricultural supply store in the village to buy a few bottles of pesticides, sprayers and masks." Li Shuanzhu took out a few hundred yuan from his pocket and handed it to Shunzi.
Shunzi took the money and said, turned around and left.
Li Shuanzhu suddenly thought something was wrong, and Ranzi told him again and again that the vegetable base focuses on a natural and green concept, and pesticides and chemical fertilizers must not be used.
"Shunzi, come back." He quickly called to Shunzi who had already run more than 20 meters away.
Shunzi returned in confusion and became anxious after hearing the reason explained by Li Shuanzhu.
"Brother Shuanzhu, when we encounter this in our hometown, we always spray it with pesticides. How can we get rid of it without spraying pesticides? You can't catch it with your hands, right? If it's a cabbage caterpillar, it's almost the same."
"Don't worry, let me think about it." Li Shuanzhu looked solemn, squatting on the field ridge and looking at the vegetable leaves in trance.
Over the years, the use of pesticides has become popular. As long as pests are encountered, almost no one considers other methods. As a result, the resistance of pests has been increasing from generation to generation, and the toxicity of pesticides has become more and more serious. As a result, the residue problem has never been fundamentally solved.
As for biological control and the like, it has always been like thunder but little rain. It is easy to establish a research project but difficult to achieve actual results. It can only be limited to a very small range.
I heard that many years ago, some people used smoke to prevent insects, which is a good method, but smoking requires a lot of mugwort, and there is no place to find it here.
Thinking about it again, Li Shuanzhu stood up and walked back and forth along the field ridge.
Shunzi stood aside, looking at him eagerly.
Finally Li Shuanzhu stopped and said to Shunzi:
"Shunzi, go to the small market and buy ten catties of dried chili peppers and two catties of Sichuan peppercorns. By the way, you have to buy the spiciest chili peppers, and Chaotian peppers are the best."
"Brother Shuanzhu, it's such a hot day, do you want to eat spicy hot pot?" Shunzi asked in confusion.
"Eat this hot pot. It's used to kill insects. Hurry up and buy it. Where does all this nonsense come from!" Li Shuanzhu shouted impatiently.
Shunzi muttered a few words and trotted towards the village.
Half an hour later, Li Shuanzhu and Shunzi were in the kitchen of their residence. They placed a large pot filled with three-quarters of cold water on the stove, lit the fire, and then added large amounts of dried chili peppers to start cooking the chili peppers.
On the other side of the stove, use a smaller pot to boil the pepper water.
As time passed, the air in the kitchen was filled with the pungent smell of chili pepper. Li Shuanzhu and his wife dipped the newly purchased masks into cold water, put them on their faces, and then used a spoon to stir them in the pot.
Shunzi bought the most expensive chili pepper, which was spicy enough. The smell came out of the kitchen, and soon the old landlord was summoned. Li Shuanzhu quickly agreed to put the lid on the pot, close the window, and then put the grunting
The old landlord sent him away.
A pot of water boiled for forty minutes. The two poured the chili water into the prepared iron bucket to cool down, and then continued to boil the next pot.
Near noon, the first batch of chili water and Sichuan pepper water were finally finished.
However, the sun is too strong at noon, so it is not a good time to apply pesticides. You have to wait until the afternoon to do it.
So I had to go and do other things first.
At 5:30 in the afternoon, Li Shuanzhu and his men returned to the vegetable field carrying large and small buckets of chili pepper water and Sichuan pepper water. Although it was almost evening, it was summer and the light was still very bright.
"Brother Shuanzhu, can this pepper water kill insects? Why haven't I heard of it before?" Shitou'er asked.
"There are a lot of things you haven't heard of. Let me let you learn a lesson this time." Li Shuanzhu came to the edge of the small rapeseed field, put down the bucket, took a small broom, put his hand into the bucket and dipped it in pepper water.
Then with a shake of his hand, he spread the chili pepper water and sprinkled it on several nearby rapeseed plants.
Shunzi and others quickly moved their heads closer to watch, and soon they all exclaimed.
"It really works, the insects all clump together." "It's really amazing."
Li Shuanzhu also stepped forward to check, and saw that wherever the pepper water touched, the grubs huddled together and struggled, which was almost the same effect as spraying pesticides.
He finally breathed a sigh of relief.
It seems that the traditional method has not failed yet. In recent years, the resistance of pests to pesticides has greatly improved, but the ability to resist pepper spray has obviously not improved. It is no wonder that no one still uses this time-consuming and laborious local method.
This method was told by his father when he was a child, and he finally remembered it in the morning, but at that time he didn't know if it would definitely work.
The experiment was successful, so he directed his men to bring a few brooms and put the pepper water and pepper water in the bucket into the vegetable field.
You can also use a water ladle to do this job, but it is too wasteful and the water is not spread evenly.
In this way, the five people worked until the sky was filled with stars before they finished consuming the water in the bucket. Now it is no longer clear, and the specific effect will not be determined until tomorrow morning.
Shunzi moved his sore arms and then remembered that he forgot to leave someone to cook dinner today. He quickly told Li Shuanzhu about this.
"It's okay, everyone has worked hard today. Let's go to a restaurant tonight and have enough food and wine." Li Shuanzhu waved his hand and said boldly.
Oh, the young men all cheered in unison, and the sound frightened the birds perched on the trees by the roadside.
Early the next morning, everyone rushed to the field to check the effect of last night's pest control. As expected, most of the pests were killed. The effect of pepper water combined with pepper water was satisfactory.
So, Li Shuanzhu arranged the work and cooked it again today, which would probably completely eliminate the bugs.
