Hot pot is steaming hot, green lettuce, cucumbers and green peppers are placed all over the table, and the bottom of the butter pot is very red. At the weekend, I came to the camp of a regiment of the Xinjiang Military Region. The smell of spring in front of me warmed my heart. The camp is stationed in the hinterland of the Karakoram Plateau with an altitude of more than 4600 meters. The lowest temperature in winter is - 30 ℃, and it is covered with ice and snow all year round. Therefore, the fresh vegetables here were once extremely valuable. Staff Sergeant Liu Lianqiang picked up a piece of lettuce and put it into a red oil pot. He smiled and said, "In the plateau, vegetables are more rare than fresh meat. How many people dreamed of eating vegetables every day? Wang Chao smiled mysteriously and said, "Come with me!" Against the cold wind, Wang Chao and the reporter came to the white plank house in the lee. As soon as the door was opened, spring came into my eyes. The iron frame around the wall of the plank house is filled with pots of green plants; The roof steel frame is covered with vines, and the "tentacles" of vegetables such as beans and zucchini are stretched out; The stove in the center of the room "crackled", and the heat from the wood burning left this vibrant "vegetable base" in spring. The officers and soldiers said that the area is remote and difficult to transport materials. Some seasonal vegetables are at risk of freezing and rotting during transportation. This problem becomes more prominent when the mountains are closed by heavy snow. Last year, the superiors organized the backbone of the battalion company and the comrades of the cooking class to hold a discussion. At the meeting, everyone gathered their ideas and decided to use the experience of local greenhouse vegetable cultivation for reference, build a "greenhouse vegetable cultivation base" using the new solar panel house, and plant vegetables based on the existing conditions. Temperature and humidity are the most important factors for growing vegetables on the plateau. After experts' investigation and guidance, they laid a layer of insulation cotton pad on the outside of the plank house, and set up a furnace, atomization humidifier, etc. in the room to ensure the indoor temperature and humidity. The officers and soldiers also soaked the vegetable seeds in warm water, and then spread the seeds evenly in the cultivation bin modified by the ammunition box. In order to improve soil fertility, they also spread "nutrient soil" evenly on the surface of the cultivation silo. In the process of planting vegetables, unexpected problems followed. Sergeant Zhang Yongqiang, the head of the cooking team, said that although the constant temperature and humidity control method was adopted, some vegetables were verdant, while others were very easy to wither. They found that different vegetables have different requirements for temperature and humidity. If indoor constant temperature control is adopted, it does not meet some environmental conditions for vegetable planting. Small inventions, small innovations, use together! They use the "insulated glass board" to "unit" the vegetable cultivation base, adopt the "one type of vegetable one unit" model, and create different planting environments according to local conditions. "With the modularization of the training base, the camp decided to divide the training task to each class of the company, one class manages one unit, and the officers and soldiers use their spare time to grow vegetables." Wang Chao said that since the end of last year, the comrades have participated in the whole process of vegetable cultivation, discussed and shared planting technology experience with each other, and also carried out a comparison - "see who grows vegetables big and green". Now, the greenhouse vegetable cultivation base independently built by the battalion has been affirmed by the superior. League leaders let each battalion learn the experience of one battalion and build its own "vegetable base"
