"A cloud is not a cloud from a distance, and a fog is not a fog from a distance."

"Actually, fog is clouds, and clouds are fog." A group of children replied in unison.

"As we walked over the mountains, we could often see the fog drifting past us and turning into clouds in the distance. The change of clouds and mist is only far and near. But when we look closely at the fog, we see that the fog is nothing more than tiny particles of water. When we really put the water particles under the microscope, we found that there were still a lot of microorganisms living in them. If you subdivide it further, you get to the particles. Water particles in nature are made up of water molecules combined with other molecules. The water molecule is a combination of an oxygen atom and two hydrogen atoms, and the yard can be subdivided. This is what our eyes see will never be all. In the Buddhist scriptures, there will be one Sumeru and one mustard seed that means. Sumeru hides mustard seeds, mustard seeds Na Sumeru. The scientific view is called the cosmology, or the epistemic view. ”

Zhang Chun spoke to the children.

The children chattered about what the teacher had said, but they didn't know what Sumeru and mustard seeds were.

Zen Master Zhenxu and the Panchen Lama and others fell into deep thought.

Zhang Chun looked at the determined attaché and said, "Actually, what you said is also correct, what you see with your eyes is only a phenomenon for a short period of time. The Buddha often talks about a flower and a world, not a short moment of flowers, but the process from budding to blooming to decaying. The reason why the world is called the world is because there is an additional world character, which represents time, and a rise and fall is a life. Although the flowers are bright, they also wither when they decay. Looking at one thing is the rise and fall. All the ways to do things are illusory bubbles, like fog and electricity. It should be viewed as such. It is said that any law that has a way to do things is limited in the long river of history. Then I would like to ask you, what you insist on is the Dharma. Or is it inaction? ”

The attaché opened his mouth, but didn't know how to answer.

"The donor is obsessed." Zen Master Zhenxu sang a Buddha.

"What is inaction?" But another attaché fought back.

"This goes back to what we said earlier that clouds are not clouds, and fog is not fog. The so-called non-action law, Taoism is called the way of heaven, which believes that heaven naturally has its law of evolution, and people can only follow it. Mr. Xu Dao, I'm not wrong, right? ”

"That's right."

"But if we look closely, we find that the so-called Heavenly Dao. There are many positive dharmas, but these positive dharmas are constantly changing over time according to the environment. It's called making something out of nothing. And the myriad of changing promising methods constitute the Heavenly Dao. This is called the creation of nothingness in the middle. All the ways to do things are illusory bubbles, like fog and electricity, and the fog I explained earlier is too much. You don't understand. And electricity is just too short-lived. By extension, change is too fast. I don't know if you can understand my explanation. ”

The attachés had different expressions, but they all nodded.

"At the end of the day, what I'm trying to say is that any policy, doctrine, or rule will have to be adjusted as the times change. If you don't adjust, you will lead to extinction, which is illustrated by the number of dynasties in China for thousands of years. The Buddha sacrificed his life for the common people, and the Buddha said that all things are equal, but does this kind of sacrifice and equality exist in Tibetan areas? You should walk around and take a look. How religion is reformed is your business. I'm an outsider who can't say anything. But my jurisdiction, I hope that in these children, their law will definitely be better than ours. This is the way of heaven, irreversible. We are just dusk and these children are the sun at seven or eight o'clock, and the future belongs to them. ”

After Zhang Chun finished speaking, warm applause rang out all around, and it turned out that some students were also attracted to him.

The Ninth Panchen Lama took his attachés back to the Bailing Temple.

Mao Shishan rushed to Lanzhou. Prepare a plan to let Ma Bufang move the nest. Song Zheyuan's 10th Army, which had just been formed, was preparing to be secretly transferred back to Lanzhou, and Zhang Guotao was also preparing to respond to the grassroots party organizations in rural and pastoral areas.

Zhang Chun didn't leave, because Wu Peifu arrived with people from the Yellow Control Committee, and they wanted to visit the greening projects in Luochuan and Hanzhong.

At the end of September, sorghum and corn and potatoes began to be harvested on a large scale on the ground in Shanxi. The entire farmland became bare.

But this is not the case in Shaanxi, where corn and sorghum are also being harvested, but some legume crops are planted underneath. The growth is good, and the farmers are plowing and fertilizing the ridges after harvesting. However, despite the ploughing, there is not much exposed land to be seen. In addition to this, there are other crops in the strip. Therefore, most of the ground in Shaanxi is still green.

"This is millet from the claw, which is also called millet in China, but this variety was introduced from Africa, and the harvest season is a little later, almost a month. The yield is not high, but the planting area is not wide, but it has a lot of rhizomes, and the effect of protecting water and soil is very good. Straw is also good for farmyard fertilizer. We mainly use crop rotation. It is very good to grind noodles, cook porridge, and make rice balls. ”

A young farmer grabs a handful of soil from the ground, the loess is still loess, but the moisture of the soil has improved greatly, and there are many dry roots in the soil.

"Most of these are roots left over from last year. This is humus left over from farmyard manure, and you see it's a little wetter than the soil, because there's a lot of microbes living in it. These white dots are the phosphate fertilizers that are applied, and they are also moist because there are many strains in them, and the roots of the plants pass through the middle of them, and the roots left behind after harvesting rot. As long as the soil is not exposed to the sun, these organisms can grow well. They speed up the degeneration of farm manure. At the same time, it also ensures the moisture of the soil. ”

"You've always kept this way of crop rotation and intercropping? It's hard work, isn't it? Wu Peifu asked.

"It's a little harder, but the income is good, and every year it gets a little better."

"What is the effect of phosphate fertilizer and potassium fertilizer, I heard that the fertilizer efficiency of foreigner fertilizer is better than ours." Sun Chuanfang is more concerned about this.

"This is the case for a short time, but the fertilizer of foreigners is a chemical compound, and the biological chain of the soil is very large. The soil will quickly harden and its fertility will decline, creating a vicious cycle. Our fertilizers are biologically activated. It is benign in the soil. In recent years, thanks to the economic crisis, foreigners have brought in a lot of phosphate rocks, some of which are guano from the island, which contains a lot of fish remains. After bioactivation, the effect is very good. The answer was a researcher from the College of Agriculture.

"Since '29, this phosphate fertilizer has responded well everywhere. This farmland can reach a flower farmland, because the decay in the soil has not stopped. Another researcher laughs.

"Doesn't it mean that bryophytes are very effective for soil and water conservation?" The question was asked by a professor at Peking University.

"Bryophytes can't be ploughed and destroyed like this very often. There are also in the farmland, but there are very few. During the rainy season, tiny algae plants also appear in the fields. But the time is very short. ”

The group walked to the bank of the river.

The pines and cypresses here are not high, and some of the denser woods are covered with dense shrubs and weeds, some of which grow so tall that they almost hide them. But they were already yellow, and the lower part had been cut with scythes by the workers of the forest farm, and several workers were pressing the grass to the ground.

Not everywhere is this kind of wood, and there is also a part of the meadow, which is planted with pasture, which is not very high, more than a foot long, and the sheep herders can be seen in the distance. However, apparently the flock was not large enough to gnaw them very short. There was a lot of sheep manure in the grass. The bryophytes were just under the grass, green and velvety, and the sheep's hooves had trampled them into the dirt, and they grew tenaciously again. Bryophytes have a lot of water underneath.

The bryophytes underneath the woods grow taller and more sparse.

"Bryophytes have small, many needle-like leaves, and they expand the surface area where condensation water. Therefore, a large amount of evaporated water is intercepted, which is the reason why the western side of bryophytes has more water. Bryophytes aren't really the main thing yet. ”

A research institute of the College of Forestry unveils a little mossy turf.

"Bryophytes form a small environment where these fine algae can survive the water condensed by bryophytes. They have a short growth period. In addition to algae, there are also some fungi, and there are at least dozens of species of fungi in this meadow. ”

"There are a lot of yellow mushrooms here. Tastes good. The workers at the forest farm laughed.

"Except for the fungus, it's these insects that grow inside."

Several people were looking with magnifying glasses.

"There's a lot of variety." Several people are talking.

"Yes, it's a miniature biological chain. All of these creatures live on the condition of water, and water circulates among them. Whether it was rain, dew, or fog, they all intercepted it. Of course, the area of such an environment is not large, and we strive to cover all the ditches, rivers, and forests in the next two years. At that time, the water of the Jing River and the Wei River will be much clearer. ”

"Yes, it is the Fen River that now has the most sediment entering the Yellow River. They also planted trees, but the effect was not obvious. I didn't expect there to be so many ways in this. The professor at Peking University sighed.

The amount of cement and sand in the Jing River and the Wei River is small, which is aimed at the previous one. But the weight of the sediment is really decreasing, and the water quality of some tributaries has become very clear. It's just that less than a third of the places that meet the target are still in place.

"It took us three years to get there. However, at this point, the rest of the world will accelerate, and it is expected that it will take another two years. You see, none of these pines and cypresses have grown yet. After two years, the grass didn't grow anymore. If not thinned, these shrubs will also die. ”

"Must be thinned?"

"Definitely, otherwise if we don't achieve species diversity, we will bring a lot of pests and diseases, and at the same time, there will be less food left for all kinds of animals. And the mass reproduction of a single species is what we call pests and diseases. The Forestry Department official replied in the affirmative. (To be continued......)
