When Zhang Chun arrived, the transportation network forest area had begun to pay attention to the planting of pine genus, metasequoia and fir.
These species are good at preventing soil erosion, but they grow slowly.
The Forestry Institute is in the process of selecting a number of shrubs and pastures for planting experiments.
The original fast-growing tree species have survived.
Some workers are building drainage canals with cement, which are compacted, the cement mortar is thin, and some soldiers are working among the common people.
They also work faster than ordinary people with their equipment.
"Why is the mortar of the canal so thin?"
Zhang Chun was also a little strange.
"The people at the Institute of Environment believe that the ditches should eventually return naturally to their state of aquatic weeds and bryophytes, and they are studying the growth habits of some bryophytes.
Only in this way can soil erosion finally be stopped.
"Zhang Chun's working group has been divided, and now there are only two people.
So whenever they went to a place, the local troops would send two warriors to follow.
The answer was the technician in charge of this paragraph.
"What to do with the water pumped from the pump room?
It is more difficult to form wetlands here, and it should be too late. ” "They're still preparing some small wetlands.
But not now, it is to build a tertiary sedimentation tank, ready to send someone to clean it.
Some villages are already using clean water. ” "What about the selection of microbial populations in biogas digesters?"
"I don't know exactly what happened, but the gas production of the digester after the selection is recovering.
Now the people at the Institute of Microbiology have learned their lesson and have rushed to the north to conduct preliminary research.
Otherwise, it will be caught off guard again.
Our people also went, and they thought that the species of the northern steppes might be more suitable for this place. ” "Hello Mr.
Zhang."
The fighters greeted each other. caused the common people to look up at Zhang Chun curiously.
"Hello everyone, let's get used to it here."
Zhang Chun asked with a smile.
"Not used to it."
The warriors laughed and laughed, "Isn't it making this place better if you are not used to it?"
Get used to getting better. ” "Ambitious."
Zhang Chun laughed.
Lizhi also smiled and said to the women huddled together, "You have to hurry, these boys are good boys." ” The two girls in the working group burst out laughing.
And the women were much shy.
Gas production from the digester is affected.
The power supply is not sufficient.
Therefore, a thermal power plant needs to be designed to reduce the dependence on biogas power generation.
Li Siguang has already sent news that they have found a coal field in Dongsheng.
However, according to Zhang Chun's requirements, he did not disclose to the outside world, and the scale of mining is only for thermal power stations and heating in the north.
In this way, the common people will no longer cut down trees to keep warm.
As for oil, an exploration team from the Qianjiang Oilfield has already selected a well location and started drilling.
Two old wells were taken over.
However, because the geological data and cores were taken away, it was only enough for research.
The sidewalks are paved with concrete, but the tram is now a military transport vehicle.
The railway line is a bit more complicated.
Some bridges are still under construction, so they are not open to traffic.
The trees on both sides of these roads are not growing well.
After all, it was just planted.

But the grass has grown.
These grasses are sown by mixing more than 20 kinds of grass seeds, but there are probably not many that can actually adapt to them.
There will be a process of survival of the fittest.
Due to the specially designed passage for cavalry and cattle and horses.
This is actually artificial grass.
Grazing is allowed in this meadow, but there is a limit to the number of rearing.
All of this has formed a wide green belt over the loess source.
Some of the forest belts on both sides of the trail have also been set aside.
In the fields, sweet potatoes and corn are interplanted, and the ridges are divided.
However, farmhouse fertilizer has only begun to be used, and the production cycle of farmhouse fertilizer in the north is slightly longer than that in the south, and farmers have not yet mastered the rhythm.
Some farmhouse manure that is not very well fermented also enters the farmland.
As for the biogas sludge, it will not play much role in the production of farm fertilizer.
On the contrary, in order to ensure the gas production of the biogas digester, some poorly fermented farmhouse manure entered the biogas digester again.
So time is of the essence.
The crops on the loess source are still very simple.
Mainly wheat, corn.
Sweet potatoes were added last year.
Potato.
This year, there are more sorghum, millet and soybeans.
The main thing is to change the previous planting method of full flood irrigation, and adopt the method of deep ploughing, row ridges, and various crops at intervals or intercropping.
Kick off the harvest season and reduce the amount of time the land is concentrated in the wind and sun.
A variety of crops naturally have a variety of agricultural processing models.
This is also the basis for the manufacture of processing machinery.
In the Loess Liang and Loess Ridge areas, only farmland has been retained in the gentle valley areas, and all the rest have been restored to forests and a small amount of animal husbandry.
The Forestry Institute cultivates economic forests such as apples, jujubes, and walnuts here.
However, it is not allowed to be too large and planted in patches.
This is mainly to prevent the occurrence of pests and diseases on a large scale.
It is not only economic forests that are lost, but also non-economic forests.
All these areas will need at least one to two years of subsidized food before they can be stabilized.
Fortunately, despite the severe drought in Hanzhong, the availability of irrigation facilities and equipment has not caused a reduction in production, and Shaanxi has been able to meet most of its grain needs, and the pressure on transporting grain from Hubei will be greatly reduced.
It seems that the efforts of the working group and the researchers have paid off.
Last year was still a voice of mourning, and although this year it is still not smooth, most of them have a general direction and some measures.
Zhang Chun has already ordered that after the completion of summer planting, all majors will go to Northwest University to summarize.
Personnel from the main research institutes of Xinmin University should be sent to participate. —————————— Zhang Chun was busy in Shaanxi.
The Kuomintang was not idle either.
In 1929, Chiang Kai-shek completed the Second Northern Expedition, and Nanjing formed a government under the auspices of the Kuomintang.
Chiang Kai-shek was elected president of the Kuomintang and commander-in-chief of the National Revolutionary Army, with Zhang Xueliang as deputy commander-in-chief.
In order to protest against the actions of the Qing Party, Song Qingling refused to participate in the election, but did not say that a ** government was established, but recognized the central government, only that the Wuhan government has a high degree of autonomy, and this Wuhan government includes Hubei and Shaanxi.
At this point, the provinces, like the Wuhan government, have announced their recognition of the central government.
With the exception of the Wuhan government, most of them sent representatives to participate in the election of senators.
The country was nominally unified.
However, the situation of warlord melee has not changed.
The Ma Jiajun of Qingganning united, and there were constantly some small frictions in the generation of Wuzhong, Guyuan, Tianshui, and Longnan.
But one of Ye Ting's armored divisions had already been formed, and the 1st Air Division had built an airfield in Qingyang.
Although there were only ten planes and only machine guns, the cavalry of Ma Jiajun basically had nowhere to escape under the search of the air force.

The harvest of summer grain gave Li Dazhao and Wu Hao confidence, and Zhang Tian's 25th Army moved to Hanzhong.
The northwest direction increased to three armies, and the Ma Jiajun was greatly panicked, and gathered heavy troops in Dingxi, built fortifications, and prepared for a long-term confrontation.
The 1st Air Force Division on the Shaanxi side also went around Dingxi every day.
Ma Bufang spent a lot of money to buy five planes, and one was shot down after one face.
It's not just a generation of wood fuselage, propeller engines, and a plane with dragonfly-like wings that is a toy in front of a jet.
Just when Ma Jiajun was discussing whether to hold peace talks.
The surprising results appeared.
Liu Qinghua led the 2nd Division of the 21st Army to attack Guangyuan successfully, and the entire 21st Army entered Sichuan and took Bazhong.
At this time, the Sichuan warlord melee generally had a result, Liu Xiang and Liu Wenhui controlled southern Sichuan, and then Yang Sen was the main series of small warlords.
The Wuhan government's entry into Sichuan was something that everyone did not expect, and Yang Sen and others formed a coalition to prepare to resist, but Liu Xiang refused.
Liu Xiang did the most business with Hubei, and obtained the most secrets of Hubei's military strength.
One of Zhu De's divisions could completely destroy him.
It's just that it didn't move because it was to guard against the Hunan army.
In June, Liu Xiang and Liu Wenhui suddenly announced that they would accept the reorganization of the Wuhan Autonomous Region government.
Janssen's coalition collapsed.
The battle was lost without much fighting.
Mao Shishan did not order Zhou Rong to continue the march, but only took Zhou Rong, Zhang Guotao, and Liu Bocheng to Chengdu to convene the warlords to form the Sichuan Autonomous Region Government.
Nothing other than the introduction of a land law and the introduction of education for all.
Large-landowners were also encouraged to give up their land and use the land transfer money to set up new industries.
Downsizing of the armies in the hands of the warlords.
Adaptation and replacement of equipment will not be carried out for the time being.
In the face of huge military pressure, the civil strife of the Sichuan army temporarily subsided, but in addition to education, whether it was the land law or the downsizing of the army, it was delayed.
Many warlords, including Liu Wenhui and Liu Xiang, were in contact with the Nationalist government, hoping that the Nationalist government would interfere in Sichuan's affairs.
