"Something wrong with the land? What's the problem? ”

Tang Hai also knew that even if it was the fish he raised and the vegetables he grew, there would definitely be a little problem. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

As the manager of the land, Tang Hai worked hard to water his crops.

People like to compare teachers to gardeners, working hard to water the flowers in the garden.

There must be problems with students, no student is born perfect, some may grow slowly, some may be introverted and silent, and some may be mad......

Parents are busy with work and don't have much time to take care of their children, so their children's growth period is spent in school, and the responsibility of teachers is not only to teach, but also to educate people, teach students according to their aptitude, and prescribe the right medicine for the flowers to thrive.

People compare teachers to gardeners, and Tang Hai is a real gardener, only in terms of growing and cooking vegetables, he is not willing to lose to anyone, so there are real experts who ask questions, and he will listen.

"Mr. Tang, do you use farmhouse manure for the soil here?"

"Yes, and seaweed fertilizer is used, is it wrong to use fertilizer? I also have cooperative farmland in my hometown of southwest China, and the plants there are better than here. ”

Tang Hai actually used super poop fertilizer, but he has been paying attention to too many people recently, so he uses it less, and only went to borrow feces from the killer whale group once on a whim......

"It's not about fertilizer......

Fertilizers are not bad, they are made by direct mining, so it can be said that they are inexhaustible, and the release of fertility is extremely fast.

Farmyard manure also has drawbacks. One is that farmhouse fertilizer is organic fertilizer, to make them rot, a lot of oxygen must be consumed, carbon dioxide is emitted, about 1 ton of farmhouse fertilizer to rot, it needs to consume 3.8 tons of oxygen, which is enough for 3.8 tons of carp to breathe a growing season, about 180 days. The other is that the total amount of fertility released by farmhouse fertilizer is large, but the release time is slow, and the average person is not sure of the time.

Tang Hai acquired a fertilizer factory that can process farm fertilizer, and there is also a recycling technology for the carbon dioxide emitted, which costs a little money......

It's just that Tang Hai's dishes are expensive, and this money doesn't need to be considered too much. There are a large number of wealthy people who like to eat this set, and feel that eating Tang Hai's food is a more conscientious way to eat healthier food.

In addition, in terms of fertilization, Tang Hai has been farming since he was a child, and if you think about it carefully, he is an old farmer with almost 20 years of experience, and of course there are no technical shortcomings......

"It's not a matter of fertilization, it shouldn't be said to be a matter of fertilization. Mr. Tang, you use the rotation method to raise the land, and the fertilizer used has also been calculated, but ...... The rainy season in Huazhou is too long, it rains more than 200 days a year, and the farmhouse fertilizer can slowly release nutrients, which just corresponds to the problem that the rain will wash away the dissolved nutrients, so Mr. Tang, your dish tastes very positive...... However, farmhouse fertilizer and seaweed fertilizer are not fertilizers rich in calcium, and it can be seen that crops are somewhat deficient in calcium. ”

Tang Hai's body was shocked!

So that's the truth......

It rains all day in Huazhou, even if it is a season when there is little rain, it is considered the "rainy season" when you put other places. In fact, the rainy season is not long, and some people will remember that 150 million people were affected by the drought that year.

Therefore, on the land of Huazhou, Tang Hai didn't notice the problem of calcium supplementation, and always felt that the vegetables grown were not perfect......

The fish is still roasting, too big fish such as the freshwater pomfret just now, Tang Hai asked Mary to fry it in a pot, and several people ate carp, which can be roasted when it blooms, smeared with salt and cumin, and the taste has a pure antiquity.

Mexicans love corn.

Tang Hai is also inseparable from corn.

A large area of corn is planted here, and it is almost harvest time, so Tang Hai picks some of it and roasts it to eat.

Xiaomeatball and Xiaobai eat happily, they are meat and vegetarian, as long as they are delicious.

The two giant eagles, the big bird and the small bird, only eat meat, but they catch it themselves. The river is now full of fish, the Asian carp grows very fast, and when the engine of the fishing boat is turned on, it is true that a group of silver carp jumps out of the water, and some jump on the boat themselves, and the two giant eagles catch fish very easily.

Mary fried the pomfret and her roasted corn at the same time, and Marlena ate the one with chili peppers and held a bunch of those without chili peppers, and Tang Hai wondered what she was going to do......

She went under a tree and chirped twice, then handed the corn up.

Tang Hai saw a red squirrel cautiously poking out of a tree hole, slowly approaching, and after finding that no one would hurt it, he happily ate it, and then there were a lot of squirrels......

Tang Hai couldn't help but think of a time when he was too tired to play with Rose and slept too hard, and when he woke up, the squirrels in the forest had a party in the wooden house......

Dr. Harry was amazed at the corn, and the fish, which he said he hadn't eaten in years, and that this wasn't a green farm, it was a super super green farm!

This shows Tang Hai's arrangement over the years......

No matter which river or lake in the world is, unless people help it rise, the water level will definitely fall.

In the past, Jennifer and Tang Hai said that many reservoirs in California are half-dry, and California's smelt fish are almost extinct, which is actually caused by the extraction of agricultural water. The water seeped out of the rivers and lakes is not much, but when it comes to comprehensive irrigation, the infiltration area is large, and the quantity is large. If the new additions can't keep up, the area will decrease.

If there are many people in California, it will inevitably build an industrial park, and it will not be cost-effective to build and transport it elsewhere. If there is an industrial park, there will be water pollution, and the water pollution will inevitably go to the rivers and lakes, and the water from the rivers and lakes will be used for irrigation......

Therefore, even for a person like Tang Hai who loves to eat, there are two things he dare not eat, that is, California rice and California lettuce.

For the past 10 years, California has tried to sell rice to China, but it has not been successful because rice is the crop that absorbs the heavy metal cadmium at the highest rate......

The second is lettuce.

Therefore, no matter how much California national treasure rice is blown, Tang Hai will not eat it.

Lettuce in California is also a frequent problem.

This is the danger of the overlap of industrial land and agricultural land.

Many people still stubbornly believe that the fish in the Great Lakes of the United States are not eaten, and there is heavy metal pollution, and the fish problem must be the most serious......

Actually, no, the most serious will be the local crops, because the crops drink more water than the fish. Moreover, crop leaves only transpire water, leaving behind heavy metals.

It is true that there are 450,000 pieces of farmland in the United States that do not meet the standards, but this means that they do not meet the standards of the United States, the Netherlands, and the world.

California is not the only country that has a serious overlap between industrial and agricultural areas......

Rice has the highest absorption rate of cadmium, so if you have the conditions, you still have to buy rice from some industrially backward areas, it doesn't matter if it is expensive, it will cost 50 yuan a month for rice.

If you are particularly wealthy, like Xiao Wang's family next door, and the water you drink is imported from Fiji, then you don't need to worry about any pollution......

In the past, there were still flaws in the rivers and places selected by Tang Hai, but after he knew that the source purification could be beneficial to shellfish, he began to plant various trees, and slowly the river water was purified, and the safety of various fishery resources, along with nearby agricultural resources, skyrocketed......

You get what you pay for.

Tang Hai is at least 5 cents of goods, he can sell it for a dollar! This is the result of these years of hard work!

Many people think that the current food does not taste as good as when it was a child, but in fact, it is not necessarily a problem with chemical fertilizers, but also irrigation water......

Dr. Harry gnawed greedily on the corn, his expression was shocked, as if he was saying in his heart that he was lying in a trough, how could there be such delicious corn! This still looks a bit lacking in calcium......

Suddenly, there was movement in the woods.

A black wolf's head poked out.

[Tips: Rice should be bought from industrially backward areas, don't always buy the same brand when buying large packages, and diversify staple foods to avoid heavy metals, as well as occasionally eat some kelp, kelp is an antidote to cadmium and lead. (To be continued.) )
