On Sunday, Xia Wei slept until half past eight and didn't get up until half past eight, when she suddenly remembered the small tomatoes she picked in the grass by the roadside when she went to the countryside. "It's useless if you don't pick it, and it won't be red in this season."

Xia Wei said: "I want to take it home for an experiment to see if it can become popular." ”

A colleague said: "You just rest, this temperature is not enough, the tomatoes in autumn will not be red, we have planted them in the field, do you think the tomatoes in the field will be red in the autumn?" No, it was ruined in the fall, and it grew on the side of the road and no one cared about it, so it was still bearing fruit. ”

Xia Wei said: "Then we have to do this experiment, you see that the temperature is suitable in autumn, and the branches of wild tomatoes on the roadside are full of fruits, and they can't bear so much fruit in summer." So Xia Wei took the little green tomato that couldn't turn red on the branch and took it home, and put it and the pear in a sealed bag. Xia Wei calculated, it should be a week now, she opened the sealed bag, she was pleasantly surprised, only to see that the tomatoes in the bag in front of her were all red, she took one and washed it and put it in her mouth, a fresh and sweet taste was refreshing, she couldn't help shouting: "Wow! It's so delicious! She suddenly remembered that in the autumn in her own field, she always plucked the green tomatoes that had been hanging on the branches and threw them aside, no matter how many unripe tomatoes there were on the branches, and she knew that green tomatoes could not be eaten. Therefore, in autumn, the villagers destroy the tomatoes and grow other vegetables, and everyone knows that the autumn tomatoes are not ripe.

Xia Wei was very happy to have this successful experiment, and she thought that if this technology was passed on to farmers, then fresh tomatoes would still be eaten in the autumn. Xia Wei knows that the tomatoes sold in the vegetable market are basically sprayed with ripening agents before they ripen, and such tomatoes have no sweet taste in the mouth, not to mention that the taste is not good, and the ripening agent is not good for health. She wants to tell all farmers about this technology, so that they can grow greener crops for the benefit of all.

wanted to do this experiment, which originated from a casual discovery by Xia Wei.

It was a long time ago, I remember that not long after I first came to the Huhu Health Center, a patient's family sent Xia Wei a bag of green persimmons, and the person who sent them said: "You put these persimmons into the sesame pole, and then put them in the cotton clothes to cover them, and the persimmons will be red in a few days, and you can eat them at that time. ”

Xia Wei happened to have a few apples at home that had not been eaten, so she avoided taking up space, so she put the apples in the bag with persimmons, and then tied the mouth of the bag.

After a few days, Xia Wei forgot that the persimmons in the bag had not yet been inserted into the sesame stem. One day, Xia Wei suddenly remembered this, she opened the bag, and suddenly, the red persimmon was exposed in front of her. She was surprised and delighted, picked up a persimmon, took a bite, it was so delicious. She told the news to the persimmon's patient's family, and the patient's family went home and tried it with apples, and the persimmons turned red. It's really a surprise, the ripe persimmon is more delicious than the one that was inserted with a sesame pole, and the place where the sesame pole is inserted will bring out a lump of persimmon meat, and there are not many that can be eaten in the mouth, but now it's good, the persimmon ripened with apples is delicious and fresh and not wasted.

The technology that this apple can ripen persimmons has spread as soon as it spreads. Nowadays, the persimmons of the farmers in the market are ripened with apples in this way. Therefore, Xia Wei thought that tomatoes should also have something that could make them ripe, but we didn't know, so we thought of pears, because pears also have a fragrance, and it was the fragrance of apples that made persimmons ripe before. Now the experiment has been successful, proving that he was right.

It would be great if farmers could apply this technique to the ripening of tomatoes. The more Xia Wei thought about it, the more excited she became. So, she's going to write it down so that everyone knows about the technology.

Somehow, Xia Wei suddenly remembered the yams (also known as sweet potatoes) that she had grown at home in the past.

When Xia Wei was very young, the potatoes planted in the family's own land have not grown very well, due to the soil quality, her own potatoes are always not as delicious as the potatoes planted by the neighbors in the sandy soil at the foot of the mountain, and they are not as good as the neighbors' potatoes, the potatoes in the sandy land are smooth and uniform in size, and they are fragrant and sweet in the mouth, exuding the fragrance of chestnuts. Looking at the potatoes in their own fields, in addition to their unsightly appearance, they also have a lot of moisture, and they are not delicious.

Xia Wei asked her blind grandfather why? Grandpa told her, "Look, doesn't that potato grow in the soil?" Therefore, the sand is soft, and the potato grows quickly and without restrictions, so it looks good. ”

Xia Wei still didn't understand and asked: "Our family's land is not sandy, what should we do, the potatoes don't grow big, they are not good-looking, and they are not delicious." ”

Grandpa said, "If you are not afraid of being tired, you can put the ashes of our plants and trees under the potato seedlings when you plant potato seedlings, and the soil will not be loosened." ”

Xia Wei continued to ask, "Grandpa, have you tried it?" ”

Grandpa said, "Of course I tried it." ”

"Then why don't you let your parents put grass and trees to plant yams?"

Grandpa sighed and said, "Anyway, they're afraid of trouble, and your father said that it would be better to put some pig manure in the stall where the potato is planted." Maybe there wasn't grass ash on it, right? ”

Xia Wei remembered her grandfather's words, and when she planted potatoes in the second year, she took her younger brother to transport all the grass and wood ashes at home to the ground, and put grass and wood ashes in the stalls where the potatoes were planted.

When the potatoes were harvested, Xia Wei was so excited, the potatoes in each stall were big and smooth, and some stalls put more plant ash, and the potatoes grew as big as pumpkins, which was so cute. Xia Wei said to her parents: "Our family's potato has laid eggs. ”

As soon as Xia Wei thought of this, she was happy. But most of the farmers nowadays try to save trouble, putting chemical fertilizers and pesticides in the soil to plant potatoes and peanuts, which is a terrible thing! Xia Wei saw in the agricultural technology book that if a pesticide is sprayed in the ground, the fruit growing in the soil cannot be planted for three years. How many farmers can know this knowledge! Xia Wei fell into deep thought.

Xia Wei thought that now the government is calling on everyone to engage in green food, but how many cadres know these agricultural science knowledge! Therefore, the promotion of agricultural science knowledge has been urgent, if you don't know this knowledge, then green food will be an empty talk! Therefore, Xia Wei also wrote down this concept, so that more people know the role and impact of scientific knowledge on human beings.
