Dar es Salaam, a city by the sea, was unusually busy at this time, with a large number of pedestrians and vehicles crowded on the not wide streets, and a few black men in police uniforms were only moving in the middle of the road. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Drive on the right-hand side, and the cars in the country are mainly concentrated in some big cities, such as Dar es Salaam, the number of cars is relatively large, but compared with cars, there may be more bicycles and motorcycles.

The locals are very crazy to drive, because there is no traffic light, so there is no car to let people or people to give way to the car, it depends on who is bold, who can pass, and in some key positions, the command and transfer of traffic depends on those traffic police.

"Didi!"

Lin Quan and they were blocked at an intersection, which is not blocked, the situation here is much better than the situation he was blocked on the road in Beijing, but the situation on the road here is quite chaotic, cars, trucks, trucks, motorcycles, bicycles and even pedestrians with dozens of pounds of heavy objects on their heads, all crowded on the road, making the traffic police in charge of the command in front of them busy sweating.

Zhang Chuan looked at his watch and honked the horn dissatisfied, but it was obviously useless, whenever there was a little gap in front of him, someone would rush out from the back, and then his pickup truck was blocked on the road and couldn't move.

But fortunately, after about five minutes, the scrambling traffic police finally let them pass, and they finally left here.

Dar es Salaam has a large commodity trading area, a large area of which is devoted to agricultural products.

It is still a traditional agricultural country, so the country attaches great importance to agriculture.

Zhang Chuan obviously knew the environment here, so he drove the car directly into the mall, found a place to park the car, and then got out of the car with Lin Quan.

"If you buy seeds, you actually have to buy seeds from our own country, these seeds are all improved, the yield is relatively high, the growth cycle is relatively short, the light in Africa is very abundant, the temperature is also very high, the growth rate of things here will be very fast, so the economic benefits are better, but this kind of seeds are not very popular in the local area, so we basically have no competitors. ”

Zhang Chuan took Lin Quan towards a Chinese seed shop and said as he walked.

Lin Quan was slightly puzzled, since China's seeds are better, the yield is better, and the growth cycle is shorter, then why don't the locals like to use Chinese seeds?

However, his doubts did not last long, and he heard Zhang Chuan explain: "The main reason for this is that the seeds we came to transport are high in yield, but after this kind of seeds are planted, their seeds cannot be retained as next year's sowing seeds, and the crops planted by the locals will actually be retained, and they will not buy new seeds every year, so they naturally don't like this kind of Chinese seeds that can't be retained." ”

After Lin Quan listened to his explanation, he was relieved, and thought to himself, no wonder, it turned out to be like this!

In fact, due to the huge population in China, the pressure on grain production is very great, which must be deeply experienced by friends living in Henan and Heilongjiang, these two places are the first and second largest grain production bases in the country, and the annual grain output of the two provinces is close to 130 million tons, close to 25% of the national output Taking Henan as an example, although the central government also attaches importance to the economic development of Henan, the most important thing is that Henan is the main grain production base, to stabilize the output of grain, and there can be no decline in output, so the requirements for the use of land in Henan are very harsh, so Henan and Hebei, these two provinces are only one word difference, but the economic structure is completely different, Hebei is to start with heavy industry, there are heavy industry factories everywhere, every winter haze is very serious, and Henan does not have such a good treatment, so it has become a major labor export province, nearly 100 million people, for the local to provide a large number of workers, and a large number of people, will naturally be squeezed out by the locals, so the reputation of Henan people is not very good, in fact, this is not because Henan people have problems, if they are given enough factories, let them take off the hat of a large grain-producing province, do not restrict, and vigorously develop the secondary industry and the tertiary industry, I believe that the situation will not be like this.

In order to increase the output of food as much as possible, the state has made a lot of investment in this area and studied a lot of things, which may be Yuan Longping's hybrid rice, which uses hybrid technology to greatly increase the yield of rice, so that the country's food security situation has been greatly alleviated.

But this kind of rice seeds, but can not be kept, because this seed is specially bred, using hybrid technology, and their own seeds if planted, will be very unstable, the yield will be greatly reduced, and even there will be no harvest, and this is almost fatal for farmers, so for this kind of seed, this thing must be replaced with new seeds every year, absolutely can not use their own seeds.

In fact, for the study of agriculture, as early as the Tang Dynasty, the Tang Dynasty had begun to invest manpower and material resources in this, and at that time it was indeed researched out some new varieties that could improve the yield, but this new variety has a very serious problem, that is, can not keep the seeds, the yield of the second generation after the seeds will decline sharply, so this thing was not promoted in the end, although the Tang Dynasty was rich and the people were strong, but after all, the transportation was inconvenient, the farmers were not used to buying seeds by themselves, and preferred to keep their own seeds, and the government did not have so much financial resources to send seeds to every province and every county in a timely manner, so except for some of this new product planted in some official fields in the suburbs of Chang'an, this thing has not been promoted.

But in later generations, it was different, because of the government's leadership, coupled with the improvement of transportation conditions in various places, and the institutions retained by the former rural cooperatives and brigades, so that the new seeds could be well promoted, and the publicity of this hybrid seed was also in place, and every farmer knew what this seed needed to pay attention to, and there would be no failure or reduction of harvest.

And this method has also been brought to Africa, when the Chinese merchants sell these seeds, they will repeatedly emphasize to the locals that this seed cannot be kept, otherwise it will greatly affect the yield of the next year, and some local people did not believe it at first, and after seeing the high yield in the first year, they were ecstatic, and kept the seeds as treasures, and then the situation in the second year made them dumbfounded, not only the yield dropped sharply, but the crops in the fields also grew unevenly, as if it was not a product of one variety.
