Chapter 1693 Authentic
The days passed like this day by day. During these days, the decision to develop the autonomous prefecture southward was passed. This development decision had a nice name - Anning Valley Development Plan.
The Anning River Valley is an important agricultural area in Liangshan Prefecture. It has superior natural conditions and unique resource endowments. Along the river are small plains connected by rivers like beads. These small plains are added to At the same time, there is the Anning River Valley Plain, which is the second largest plain in Sichuan after the Chengdu Plain. It is known as the "Granary of Southwest Sichuan" and is said to be "even if you can stick a chopstick in it".
The development conditions here are relatively good. The population and towns are densely distributed, the degree of industrial concentration is relatively high, and various characteristic industries are beginning to take shape.
The Anning River is a tributary of the Yalong River. It was named after the Qing Dynasty. It has two sources, the east and the west. After the two sources merged in the southeast of Daqiao Town, Mianning County, Liangshan Prefecture, it was first called the Anning River and passed through Mianning. , Xichang, Dechang, Miyi, and merge into the Yalong River in Yanbian County.
Although it is a tributary of the Yalong River, the shape of the Anning River Valley is different from other tributaries on the main stream of the Yalong River. It has a shallow cut, wide valley, twists and turns, and staggered branches, forming a huge valley at the intersection of the main stream and the tributaries. The alluvial fans, floodplains and river-centre islands are dotted all over the place, and the unique plume-shaped water system finally formed the narrow and long Anning Valley Plain.
In a broad sense, the Anning River Valley Plain includes the valley flat dams on both sides of the middle and lower reaches, including Miyi County, Yanbian County and other places in Panzhihua City. It covers an area of about 960 square kilometers, which is exactly the official One ten thousandth of the published land area of our country.
Because the surrounding mountains block the cold air, like the Shudu Basin, it is like a closed "warm basin". In addition, it has a subtropical plateau monsoon climate, which is warmer than the Shuzhong Basin.
Because the temperature is higher, the frost-free period is longer, and the soil is fertile, and the rivers flowing from the surrounding mountains can be used as irrigation water sources. The Anning River Valley has always been the source of rice, corn, potatoes, cocoon silk, fruits, vegetables, and flowers in Sichuan. , meat and other production bases, and its specialty fruits, such as early-ripening loquats, mulberries, mangoes, pomegranates, papayas, etc., are all top-quality.
The climate is mild, with distinct seasons of rain and drought. The air is clean, the sunshine is long, and the surrounding mountains mean that even in the severe winter, the wind and sunshine are beautiful, the mountains and rivers are beautiful, and it is as warm as spring; In midsummer, the weather here is still clear, cool and pleasant, and it is also a good place to escape the heat.
Because there are more than 320 sunny days a year and the air is fresh, the autonomous prefecture is also known as the "Moon City". Also because of its latitude advantage and climate observation advantages, it was selected as one of the three major aerospace centers. It became a launch base for rockets and satellites.
A very important part of the plan is to repair the roads. In addition to connecting the ferry, which connects Sichuan and Yunnan, it also opens up the internal ring line and strengthens the transportation links among the six southern counties. It has also become the focus of the autonomous region's construction.
This plan has been recognized by the province, which believes that it takes into account both "external circulation" and "internal circulation", and focuses on grain and special Chinese medicinal materials, fruits, flowers and other economic crops, making the Anning Valley a place Giving full play to your advantages is a good way to develop on your own without waiting or relying.
With support from above and a clear direction of development, cadres and masses from the autonomous prefecture and southern counties were mobilized.
Compared with the liveliness of the Anning River Valley, the northern counties are a little more deserted. Meigu is also in the northern part of the state capital, but at least in Lianhe Township of Meigu County, it is not deserted at all.
People from the Autonomous Prefecture Academy of Agricultural Sciences came over for inspection. In fact, their main work is in the prefecture. They came here mainly to inform the township of the results. At the same time, they also wanted to conduct on-site inspections and compare the actual local hydrogeological conditions with the data to determine the results. Authenticity.
The result made Zhou Zhi and others very happy. That is, the Meigu Valley in front of Lianhe Township and the entire "paw" of the back mountain, which is the valley area, are very suitable for planting soft-seeded pomegranate trees.
Pomegranate trees actually have certain requirements for soil quality, because the root system is more sensitive to moisture, and anything that is too wet or too dry will affect its normal growth. Therefore, the best planting soil is well-drained and loose. Sandy soil with good air permeability.
If it is changed to other places, in order to avoid the occurrence of water accumulation, it is often necessary to improve the mechanical energy of the soil. It is necessary to add an appropriate amount of sand or perlite and other materials to the soil to improve the permeability of the soil. There is no need for it at all in Lianhe Township, because except for the soil in the valley, the soil on the half slope is basically red mud mixed with weathered sandy soil, which is equivalent to the natural mixed pomegranate planting soil. .
The only deficiency is soil nutrition, which needs to be solved through scientific management measures such as fertilization and bottom fertilizer.
There is also the pH of the soil. Pomegranate trees are generally suitable for growing in neutral or slightly acidic soil with a pH value between 6.0 and 7.5. If the soil is too acidic or too alkaline, it will affect the normal growth and fruit quality of pomegranate trees. Therefore, the pH of the soil should be tested before planting and adjusted if necessary.
Lianhe Township does not need it either. Generally acidic soil is humus soil. Land like Lianhe Township has been washed into the Meigu River and is now slowly recovering.
Alkaline soil is generally the result of salt and calcium deposits in arid climate areas, excessive lime application, and weathering of basic rocks.
This problem does not exist in Lianhe Township. Although there is a dry season and a rainy season for half the year, there is no shortage of water. There is no rain for two or three months in the dry season, but there is precipitation almost every day during the rainy season. The salt in the land The alkali cannot be deposited at all.
In addition to needing well-drained soil, pomegranate trees also have water requirements and need to be watered every half month.
After the arrival of the mountain dragon, the water source problem has been basically solved, and this obstacle to development no longer exists.
Finally, there is light. Pomegranates are sun-loving by nature. When planting, you should choose an area with sufficient sunshine and more than 1,200 hours of sunshine per year. This will help the plants grow lushly and increase yields. If the light conditions are good, If planted in poor areas, poor quality pomegranates will occur.
The autonomous prefecture known as the "Moon City" basically has more than 2,400 hours of sunshine, which is more than double the requirement for pomegranate trees.
So basically Lianhe Township is an ideal place for planting soft-seeded pomegranates, because the rainy season is from December to March every year, and December to February is considered a dormant period, so it doesn’t require much water. You only need to water once in February, twice in March, and you don’t have to worry about it when the rainy season starts in April.
In addition, if you apply fertilizer again during the flowering period in April, the management of the pomegranate tree will be completed.
Of course, this is just the basic requirement for extensive management. To reach the ideal level of a soft-seeded pomegranate seedling base, annual high-branch layering, flower and insect control, tree dwarfing control, etc., is the way to go. of knowledge.
But just like the poplars in the north and the bamboos in the south, if plants are not cultivated on the ground, it will be as difficult as the sky, but if they are on the ground, it will be twice the result with half the effort.
For example, the dendrobium that Zhou Zhi moved from Jiachuan to the capital of Shu was really difficult to grow. In the capital of Shu, one dendrobium was really difficult to raise. Three pavilions out of ten pavilions could not be fed. But in Jiachuan, it was thrown into the sand. It grows on rocks, and it grows on rotten wood.
There is nowhere to reason.
