Chapter 39 Saline-alkali Land
Left Shuya's temporary laboratory.
Jiang Miao came to his experimental greenhouse alone.
Ke Yong and another bodyguard were sitting under an umbrella not far away. The two seemed very relaxed, but in fact they were secretly observing their surroundings vigilantly, especially the nearby intersections that were close to the laboratory and experimental greenhouses. .
Next to their parasols were Li Wenna and another female bodyguard. They were in the same group as Shuya.
Among them, Li Wenna was sitting at the table, tapping the laptop keyboard with her hands from time to time, doing some work.
Although she is Shuya's secretary, she still has to help the farm handle some things, especially the communication with the headquarters. Lu Weibin has left all the work to Li Wenna.
Jiang Miao inspected various crops in his own experimental greenhouse.
A lot of crops have been planted inside.
Including ginseng fruit (cantaloupe and eggplant), alfalfa, soybeans, tomatoes, cucumbers, and rice.
These greenhouses have a total cultivation area of 5 acres.
Among them, tomatoes, ginseng fruits, cucumbers and soybeans are already blooming and bearing fruit.
The alfalfa is growing extremely luxuriantly, and the rice is still heading.
Two acres of the land were transformed into artificial saline-alkali land, which was divided into five types of saline-alkali land to simulate mild saline-alkali land, moderate saline-alkali land, severe saline-alkali land, transgressive saline-alkali land, and inland saline-alkali land.
These saline-alkali experimental fields are filled with alfalfa, soybeans, and rice.
However, growth conditions vary.
Although it is a new variety improved by Jiang Miao through identification panels and breeding techniques, the new variety will also be acclimatized.
You know, in order to screen out suitable new varieties, he consumed 3 tons of non-GMO soybeans to select 37 valuable gene mutation varieties from these 3 tons of genetically mutated soybean seeds.
The same goes for other rice and alfalfa.
If we relied on traditional breeding methods, it would take three to five years to select useful varieties from 3 tons of genetically mutated seeds.
But Jiang Miao can reduce this time to a few weeks.
Only those genetically mutated varieties that have been initially screened are qualified as varieties for planting experiments.
The soybeans, alfalfa, and rice in these experimental fields before us are excellent varieties carefully selected from tens of thousands of mutations.
"Can't DD24 adapt to high potassium?" Jiang Miao recorded the situation of this variety in the record book using symbols and words that only he could understand.
Walking through the experimental field of No. DD24 soybean.
The next few soybean varieties performed unsatisfactorily.
Some soybeans can tolerate salt-alkali, but not drought;
Some are drought tolerant, but not disease tolerant;
Some other performances are okay, but the output is low.
In front of the experimental field marked with No. DD28, Jiang Miao squatted down and looked at the fruitful edamame pods under the branches: "The variety No. DD28 is quite good. It is not only resistant to high-salinity seawater, but also resistant to diseases and insect pests, and its branches are relatively small." Strong, with good lodging resistance and good yield..."
He roughly estimated the yield of this soybean plant. If converted into yield per mu, it would probably reach about 183 kilograms per mu.
The yield per acre is very high.
Because the management of this experimental field is very extensive, and a large amount of chemical fertilizers and pesticides are not used, it is absolutely terrifying to be able to achieve this level of yield per mu.
Of course, the soybean yield per mu in some areas of the country can also reach very high levels.
For example, in some soybean fields of the Western Region Production Corps, the yield per mu can reach about 230 kilograms. However, the prerequisite for this kind of yield is good field management, rational use of fertilizers and pesticides, and good water conservancy to achieve this level.
Similarly, in America's Mississippi River genetically modified soybean production area, the average yield per mu can reach about 220 kilograms. The problem is that genetically modified soybeans have issues such as source safety, genetic contamination, and safety sensitivity.
The DD28 carefully selected by Jiang Miao can be directly irrigated with seawater or salt water from inland lakes. At the same time, under extensive management, it can still reach a yield of 183 kilograms per mu. This is definitely a variety with great potential.
Unfortunately, the cold resistance of No. DD28 is not very good and cannot withstand low temperatures below 15 degrees Celsius.
Jiang Miao is not disappointed with this, because this is only the first generation variety. In the future, we can continue to improve on the basis of DD28, and even consider opening new experimental fields in the coastal saline-alkali land of the Bohai Bay.
However, he has no thoughts of going north for the time being.
On the one hand, there is no need to be too hasty. He only mastered the artificial breeding technology of eels last year, and then developed several new strawberry varieties. If he comes up with such excellent soybean varieties, it will easily attract attention.
On the other hand, it is natural that Hailufeng's financial resources are not strong enough to invest on a large scale. If a new variety of soybeans is launched at this time, ordinary growers may not foot the bill, which is not conducive to promotion.
After all, the new varieties developed by Jiang Miao tend to be salt-alkali tolerant varieties. For ordinary farmland, the difference between planting salt-alkali tolerant varieties and planting other varieties is not particularly big.
The alfalfa and rice he produces tend to be salt-alkali and drought-tolerant varieties.
The reason why we choose to be salt-alkali and drought-resistant is because a large part of the domestic land is saline-alkali land.
The scale of domestic saline-alkali land has reached 99.13 million hectares, equivalent to 1.48695 million acres, almost reaching one acre of saline-alkali land per capita.
Among them, 150 million acres of saline-alkali land have potential for transformation, which is also the research direction of many domestic agricultural research institutions.
However, saline-alkali land that is easy to transform is not Jiang Miao’s goal. The saline-alkali land he is looking for is the remaining billions of acres of saline-alkali land that is difficult to transform, because salt-alkali and drought-tolerant varieties can be planted directly on these saline-alkali lands without the need for Make special soil improvements.
Even if one-third of the saline-alkali land can be cultivated, this is an extremely impressive breakthrough.
The scale of domestic soybean imports from abroad was only about 100 million tons at its peak.
As long as one-third of the saline-alkali land can be planted, the planting area can reach about 430 million acres. If all DD28 is planted, the yield per mu can reach 183 kilograms, and 430 million acres of saline-alkali land can produce 78.69 million tons of soybeans.
Coupled with the domestic soybean production capacity, it can almost completely replace the share of imports.
Of course, it is impossible to completely replace imports.
After all, if there is no domestic import at all, the global soybean market will inevitably collapse in an instant. Not only farmers in America will suffer heavy losses, but farmers and agricultural companies in South American countries and Lao Maozi will also suffer.
What's more, without importing soybeans, it will be difficult to reduce the trade deficit, which will make other countries even more reluctant to purchase domestic industrial products, thereby further moving the global economy towards isolation and trade protection.
Therefore, even if Jiang Miao introduces better saline-alkali tolerant soybeans, it is estimated that the planting area will not exceed 100 million acres.
If this area is exceeded, foreign soybean imports will inevitably need to be reduced by more than 20 million tons, which will inevitably only reduce the export quota of some regions.
This impact can have serious knock-on effects.
Originally, others could only make money by exporting agricultural products and minerals, but now they have suddenly cut off the import of hundreds of millions of tons of commodities every year. Without foreign exchange earnings, others naturally have no money to import industrial products.
Therefore, in this case, the official will take the overall situation of the global economy into consideration, and Jiang Miao's new soybean variety will only become a strategic reserve technology, and will not be fully promoted until it is absolutely necessary.
It is estimated that tens of millions of acres will be planted first, taking the opportunity to suppress the arrogance of the four major grain merchants ABCD, suppress the price of soybeans, and then continue to maintain the scale of soybean imports.
There is no way, the domestic industrial chain is too terrible, covering almost all types of industrial industries.
In this case, it is necessary to ensure that there is enough market for industrial products to absorb these production capacities. Therefore, the scale of the trade deficit must be controlled to prevent other countries from becoming too poor.
Otherwise, there will be a trade deficit of several billions or tens of billions every year, and we are not America and can turn on the nuclear-powered money printing press, and there will definitely be a day when it becomes unbearable.
Maintaining the scale of imports is a means of balancing the trade deficit.
