At present, the biological population composition of agricultural ecosystem is the result of human selection. Generally, only biological characters that meet the requirements of human economy, such as high yield and high quality, are preserved and developed, and can only be expressed under specific environmental conditions and management measures.


    Once the environmental conditions change dramatically, or the management measures can not be met in time, their growth and development will be affected due to the loss of the original adaptability and stress resistance, resulting in the decline of yield and quality.


    Human choice also reduces the species of organisms, simplifies the food chain, and weakens the self-regulation ability of the system through the mutual restriction and promotion between different organisms.


    All of these will lead to instability or volatility of agricultural ecosystems. It also shows that various technical measures must be taken to adjust and control the system to reduce the fluctuation.


    Ecological circular agriculture emphasizes the overall function of agricultural ecosystem. Based on the principle of "integration, coordination, circulation and regeneration", the ecological circular agriculture should comprehensively plan, adjust and optimize the agricultural structure, so as to make the agriculture, forestry, animal husbandry, sideline, fishery and the primary, secondary and tertiary industries in rural areas develop comprehensively, and make each industry support each other and bring out the best of each other. While improving the comprehensive production capacity, it also allows people to reduce the damage caused by the intake of various chemical fertilizers and pesticides, so as to reduce the incidence of diseases.


    These are the original intention of Liu Yang to develop this ecological circular agriculture.


    He was typing on the keyboard, listening to the sound of talking outside. Liu Yang looked up, but found that Shao Xingyu and Ma Zhigang came in.


    As soon as two people entered the door, Ma Zhigang complained: "I said, throw us into the hotel. What are you doing yourself? I said, I''ll take good care of your department store. It''s in the center of the city. It''s not only good location, but also convenient transportation. I''m going to buy it and build the first star rated hotel in Huling county. What do you think? "


    What Liu Yang listened to was a curl of his mouth: "this? Don''t look for me. That place belongs to other people''s supply and marketing cooperatives. I don''t even think that''s what I said... "


    "Who are you coaxing? On the ground of your Huling County, are there any units you can''t manage? " Ma Zhigang was very impolite and sat down on the sofa opposite Liu Yang. Shao Xingyu turned to Liu Yang and said, "let me look at our Liu Shu. Remember what kind of airplane is this I''m dizzy. How can you work hard to please me? Ecological circular agriculture I said, if you want to make an eye-catching achievement, I advise you not to touch this thing. It''s too much trouble... "


    "Well I haven''t finished what I said. What''s wrong with you... " Ma Zhigang said unhappily on the side. Shao Xingyu glared at him: "shut up, I can''t watch my brothers jump into the fire pit without saying a word Let me tell you, Liu Yang, our group has farms like this in Sweden and Japan, and the products are very popular. However, it is not suitable for this kind of thing in our country. I don''t know what kind of dizziness you are making when you are so smart. "


    Liu Yang said with a smile: "a man''s husband has something to do and something he doesn''t do. Does it have to be linked with his political achievements?"? Can''t you do something for the common people in a down-to-earth way? "


    "I''ll go. The more you say, the more you think about Marx. You think you''re the only one in the world who''s a real Bolshevik? You''re stupid, you know Shao Xingyu is very excited to roar at Liu Yang.


    Liu Yang quickly stopped his words: "OK, OK, you tell me what you two people are doing? I can''t make a phone call. Why did I come to my office? "


    "What''s the matter? Is your office still the presidential palace? Can''t we come and see it? " Shao Xingyu shook his head and said, "I know, you certainly didn''t listen to what I said just now. If you really want to do this thing, I can leave a word of comfort for you. When your green products come out, I can sell you as much as you can But I''m afraid I''ll be fuckin ''retired after you''ve made it! "


    Liu Yang pushed his hands forward with two empty strokes: "cut, why are we going to sell the good things we produce abroad? We''ll keep it for ourselves. Don''t worry about it. You''d better tell us what you''re doing


    "Hoo You just want to piss me off... " Shao Xingyu took a deep breath, and then he took out an envelope from his pocket and threw it on Liu Yang''s desk: "Damn it, you don''t tell me when you get married. Since we are here, we can''t pretend that we don''t know, can we? This is what you mean You can''t put it off. Also, take your wife and invite us to dinner in the evening. It''s not easy to say this on the phone, so I and Ma can only help ourselves and go to your place in person. "


    When Liu Yang got married, in addition to receiving a few gifts from the leaders of the municipal Party committee, all the gifts from the subordinates of Huling county were confiscated. But Shao Xingyu this envelope, Liu Yang also know that he can not push out. Therefore, it is only a wry smile and thrown into the drawer: "how funny, but also let you spend money. Well, my wife and I have a toast to you tonight But let''s talk about it first. My wife is pregnant, so let''s skip those programs? "As soon as he said this, it was ma Zhigang and Shao Xingyu''s turn to smile bitterly. The heart says like your wife? Even if she is not pregnant, we dare not joke with her? We come to this group of students, rarely did not suffer from her loss. At that time, I didn''t know she would be with you


    How do you think about this matter? It''s weird. On the one hand, it''s because of the face of the students. On the other hand, it''s afraid of Zhao''s quiet bravery. Shao Xingyu and Ma Zhigang dare not tell each other.


    In the evening, Liu Yang took Zhao Jingjing to Huling hotel. When they met at the table, they realized that most of them and Zhao Jingjing were acquaintances.


    After everyone chatted, Liu Yang understood why the deep feeling on Ma Zhigang''s face was so wonderful when he said that he would not let them make trouble in the afternoon. But it turns out that his brother-in-law Zhao Guohao likes to play in Ma Zhigang''s Yindu guild hall, which makes some things happen. For this reason, Ma Zhigang''s Yindu guild hall was almost smashed by Zhao Jingjing.


    Liu Yang did not expect that Zhao Jingjing, who has always been quiet in front of himself, is like a cat deterring rats in front of Shao Xingyu and Ma Zhigang.


    After drinking a few cups of wine, Ma Zhigang put his hand on Liu Yang''s shoulder and said with a bad smile: "Hey, hey What a surprise! Mei, the first thorn in the capital city, was given by your black horse... "


    I feel that Zhao Jingjing has been subdued by his brother. Ma Zhigang hasn''t said a complete word. Zhao Jingjing points to him and shows his eyebrow slightly: "Ma Zhigang, what do you want to say? Don''t think that if I''m in Huling now, your Yindu guild hall will be fine. I just need a phone call now, and your broken place will be razed to the ground. Do you believe it or not? "


    "Er Did I say something wrong? Can I have three free drinks myself Ma Zhigang immediately on the bitter gourd face said.


    His appearance made Lin Yuxian, Wang Shiqing, Yao Shuqin, Deng Chuang Chang, Zhang Ning and Du Yiran laughing. However, in this laughter, a few people are happy and a few people are frightened, but I don''t know.


    Du Yiran''s legs under the table, gently touched Zhang Ning''s legs, two people''s eyes gently touched and immediately separated. Looking at Zhao Jingjing''s big stomach, their eyes are filled with joy and bitterness


    Ma Zhigang and others stayed in Huling County for three days. During these three days, except Du Yiran, Zhang Ning and Yao Shuqin, everyone else had a deal with the relevant departments of Huling county. Some of them are buying and selling products, others are investing in running factories. In addition, Shao Xingyu brought the two Japanese women, and they actually reached an investment intention with Huling county.


    This result makes Lin Yufen feel a little surprised, but Liu Yang is nothing strange. Although Shao Xingyu didn''t specifically say anything to himself, when he introduced apricot Yamamoto to Liu Yang, the news he said was enough.


    The Japanese factory collapsed in the earthquake last year. They have recovered from the earthquake and are now focusing on how to make money.


    They are eager to find a suitable place to invest and build a factory, and Huling county is not the first stop of their investigation. Although Huling county does not give any special preferential policies like other areas, Yamamoto Xingzi signed an investment intention with Huling County after comprehensive analysis.


    When they came, they drove two Mercedes Benz business cars, but they left with a Honda SUV. Liu Yang has already got in touch with Professor Zhu from the Provincial Academy of Agricultural Sciences. He went to the provincial capital to talk with experts from the Academy. Of course, that''s not what Shao Xingyu and Liu Yang said.


    Thank you for coming to Huling county to see me. Thank you for your great support in my work. No matter how, even if you can''t be sent back to the capital, it''s OK to send them to the provincial capital.


    The road from Huling county to the urban area is no longer passable. This time, Liu Yang asked Feng Feng Feng to drive his own Honda cross-country to lead the way in front of him. He left the county and went west to bypass Jinjia county. From Jinjia County, he directly turned onto the expressway leading to the provincial capital.


    In this way, it was more than 50 kilometers away. When the three cars arrived at the provincial capital, it was the lunch time at noon. Originally, Shao Xingyu and Shao Xingyu spent a day in the provincial capital, so they settled down in a hotel at noon and had a simple meal. Shao Xingyu and his wife went to play, but Liu Yang asked Feng Feng Feng to take him to the Provincial Academy of Agricultural Sciences.


    When you come to the provincial capital, you can''t contact sister Fang. In fact, Professor Zhu of the Provincial Academy of Agricultural Sciences is also Fang Yuzhu''s help. Otherwise, Professor Zhu doesn''t know who Liu Yang is.


    On the way to the Provincial Academy of Agricultural Sciences, Liu Yang took out his mobile phone and called Fang Yuzhu. Unfortunately, Fang Yuzhu went to Beijing for a meeting yesterday, saying that he would not come back until the day after tomorrow.


    Knowing that Liu Yang is now in the provincial capital, Fang Yuzhu hates the root of her teeth.


    I''m looking forward to the time when this little enemy can come and see each other. It''s very good that he didn''t come after waiting for him for such a long time. Now that he has returned to the capital, he has gone to the provincial capital.


    It''s really hateful!
