Either that knowledge is the primary productive force, Xu Yi is also a child who grew up in the countryside, and he only had the opportunity to understand a little about the situation that causes premature aging of crops in the first two years.

It is said that corn and rice have been yellowing early, and lodging occurs every year, but the villagers have always thought that this is a disease, but they do not know what the problem is.

Fortunately, the land in the village is surrounded by mountains, so the wind is not very strong, and lodging does not happen much. Occasionally, there were only sporadic lodging attacks, at most the yield was reduced a little, and the harvest was more difficult, and none of them were regarded as a major event.

However, the year before last, there was a large area of lodging in the rice fields in the village, and it continued to spread, often only a small lodging today, and a large one tomorrow.

The villagers were all anxious to get on fire, but they were also at a loss. It was the village chief who called and invited people from the county's agricultural technology station to inspect it, saying that it was a serious damage caused by rice planthoppers, and asked the villagers to buy carbaryl and apply medicine to all the fields, so that the disease could be controlled.

Unfortunately, the lodging rice had already died, but fortunately the weather was good that autumn and the lodging occurred relatively late, which did not affect the yield much. It was this lodging rice harvester that could not be harvested, so it could only be cut down little by little by hand.

The people in the village worked hard for almost half a month, and finally harvested all the rice before the autumn rains.

At that time, the agricultural technology station distributed some pamphlets to every household in the village, and Xu Yi still saw this pamphlet at the village chief's house, and vaguely remembered what was written on it.

The causes of premature plant aging are, in general, nothing more than internal and external causes.

Internal causes are naturally the factors of nutrient imbalance, transfer, and disease in crops, while external causes are inseparable from soil, climate, and insect pests.

Xu Yi held his chin and analyzed it the same.

Soil, climate and insect pests can be ruled out. Then the rest can only be caused by some internal factors of the tomato itself. For example, diseases can be eliminated. Nutrient imbalance pressed by space" but there is a request. The principle of "must respond" also does not seem to hold, and it seems that all that remains is that there is a problem with the transport of nutrients.

If there is a problem with the space itself, then obviously other crops will also have an abnormality, but only these few tomatoes have a problem.

After thinking about it, Xu Yi felt that there could be only two reasons for such a result: one was that he left too many fruits, which caused the plant nutrients to be overabsorbed by the fruits, causing them to die early. The second possibility is that there is something wrong with these seeds. As a result, the tomato plant cannot synthesize enough nutrients, and even can only rely on decomposing its own plants to ensure that the fruit is ripe, which is also the reason why annual plants tend to die automatically after the fruit is ripe, but the tomato plant dies too early, even if the nutrients decomposed by itself are not enough to make these tomatoes fully ripe.

The first reason is unlikely.

Other plants in the space also produce a lot of flowers and fruits after watering, but there has never been a shortage of nutrients, and it is impossible for this to appear on the tomato alone.

As for this hypothesis, I can wait until I go back and replant a few tomatoes, and try to thin the flowers and fruits to see if premature aging will occur to confirm it.

In the second case, Xu Yi feels that it is very likely to happen.

Seeds, too, have a lifespan. If it is stored for too long or in improper storage conditions, it will cause damage to the embryo. On the one hand, it will affect the germination rate, and on the other hand, there may be various problems in the growth cycle. As far as I know, if the cabbage seeds are stored for too long, it is likely that they will sprout after a long time of planting, and that kind of sprouting is not equivalent to a disguised premature aging. However, even if the cabbage is studded, it can make the vegetable seeds ripen, but how can this tomato die before the fruit is ripe?

These seeds were collected by Zheng Huaiyuan's mother, and I don't know how long these seeds have been stored in Langdao, let alone whether something happened in the process of storing them.

But in any case, the remaining tomato seeds may not be able to be used anymore except for experiments. If you want to eat tomatoes, you'll have to find some seeds - you always have to buy cherry tomato seeds anyway.

Or next time it's empty, go to the town on the side to look for it, and think about what seed store there should be, otherwise there are so many vegetable fields outside, where do the seeds come from?

Sighing, Xu Yi reached out and grabbed a tomato in front of him.

Tomatoes, which belong to the same family as potatoes, also contain a lot of solanine when they are not ripe, and they will have a spicy taste when eaten, and they may even be poisoned if they eat too much. Xu Yi, who knew this very well, naturally didn't want to pick this tomato to eat, he just wanted to pick one out of a research mentality and just see how the development in this thing was.

But to Xu Yi's surprise, his hand had just touched the tomato, and before he touched the fruit stalk behind him, he watched the tomato in his hand fall down with a click. However, tomatoes that are not fully ripe usually do not fall off the fruit stalks and receptacles at all, and even dead tomatoes do not fall off so easily. None of the tomatoes showed signs of dehydration. And those tomato leaves are only slightly yellow, not falling off at all, how can this tomato fall so easily, this kind of fruit is really sick!

Suspicion is suspicion, Xu Yi didn't stop, and when he saw the tomato falling, he subconsciously grabbed it backhand and grabbed the tomato in his hand. But after grabbing the tomato, Xu Yi felt that something was wrong, why was this tomato soft?

Although raw tomatoes are not as hard as apples, they are still hard to the touch, and even those tomatoes bought from the vegetable market are not so soft.

If it is not a diseased and rotten tomato, only a fully ripe tomato will become soft because it is ripe. There are even some overripe tomatoes that can easily crumple the flesh as long as you put it on your hand and knead it gently, or even knead the whole tomato into a packet of sugar water wrapped in a skin.

Generally, if the tomatoes on the market are not selected for a relatively hard variety, they are often picked in advance for the sake of easy storage and transportation, and they will be picked in advance without waiting for the tomatoes to be fully ripe. On the one hand, it can avoid tomatoes becoming too soft after ripening, and being lost during storage and transportation. However, this also leads to incomplete saccharification of tomatoes, which makes the tomato more sour, less sweet, and less unique to the tomato.

The vegetables and fruits on the market are all like this, which is one of the reasons why many people criticize that today's vegetables and fruits are not as delicious as they used to be - because you can't eat fully ripe things.

Or the only ones in the vegetable market that are really ripe are the vegetable sellers you can see every day!

After looking at the tomato in his hand for a while, Xu Yi patted his head and laughed self-deprecatingly - it seems that he has a preconceived idea that this tomato is a problem and a joke!

The color of the tomato in Xu Yi's hand is indeed still green, but if you look closely, you will find that this is still a little different from ordinary tomatoes.

The tomato is not actually raw, on the contrary, it is too ripe to ripen. This tomato looks green at first glance, so most people think of it as a raw tomato. However, if you look closely, you will see that this green color is actually completely different from the greenish green of raw tomatoes, which has a bit of blue-gray color. The top of the tomato in Xu Yi's hand is actually a little grass yellow in the green, gradually changing towards the back, and by the middle and back of the tomato, it has completely turned emerald green.

Xu Yi hasn't been at home for a few years, and he hasn't grown vegetables for many years, plus he usually eats tomato scrambled eggs in the summer and scrambled tomatoes in the winter in the canteen (casually complain, no matter whether the restaurant or the canteen is the same), the tomatoes in it are basically red, so I forgot that there is this thing.

In addition, this tomato is not big, and the tomato seedling is also a picture of the end of his life, so he will directly regard this as a raw tomato.

In fact, this tomato is completely ripe, and there is nothing wrong with this tomato at all!

The real name of this green tomato is unknown to Xu Yi, but the people in the village call this thing "thieves don't steal", which means that when a thief comes, he will think that the tomato is not ripe at all, and he will not steal it at all. In fact, don't talk about thieves, if you are an inexperienced owner, you have to learn to steal peaches in the middle of the night when you see this - pick a soft pinch!

These tomatoes are small in size and remain green throughout the growing season until they are ripe, and do not turn red or yellow at all.

The more Xu Yi looked at it, the more he liked it, and directly brought the tomato in his hand to his mouth and took a bite. He immediately noticed that the skin of this tomato was particularly thin, it was really sticky and broken, and the taste was unusually soft, and the taste was sweet and sour in addition to the sweet and sour taste of ordinary tomatoes, and there was a fragrance far better than ordinary tomatoes filling the entire mouth. He was sure that even the cherry tomatoes could not compare to the texture and taste of the tomato.

Looking at the remaining half of the tomato in my hand, I saw that the thick flesh was covered with dots of light like fine sand, wrapping the gelatinous flesh in the middle like melting jade, and the tomato inside was more like a small piece of topaz wrapped in a layer of chalcedony, which looked very beautiful.

Xu Yi ate the tomato in two bites, and reached out to pick a few more, and ate five or six until his stomach was slightly swollen before stopping.

Each of the tomato seedlings was fully ripe, and Xu Yi even picked the top one of the top tomatoes on the top string - according to the growth law of tomatoes, this one should be the last to ripen, and the result was also completely ripe.

Xu Yi knew in his heart, which is not difficult to explain that the tomato seedlings will look like this - the tomatoes are all ripe, the nutrients in the branches and leaves should be almost consumed, and the plants will naturally die.

If you don't pinch it and fork it, it may grow taller and produce more tomatoes.

However, looking at the shelves full of tomatoes in front of him, Xu Yi felt that his eyes lit up.

What kind of cherry tomatoes are you looking for, even if it's that kind of small tomato, will it taste better than this, can it compare to the gimmick that this green tomato can bring? (To be continued......)
