New grass for the national level 2 protected plants

Yesterday, the laying work of replacing warm season type turf was completed, and the next work was compaction and grass mending and other details But who knows that there are still many unknown stories about the change of turf: as a national plant protection grass, how has it been exported for domestic sale? How did the post-80s returnees' turf experts command the turf replacement of 8000 square meters? Wait for our reporter to uncover one by one for you Chen Qingqi, a 26-year-old from Qingdao, is the commander of the post-80s returnees "I studied in Sweden from 2009 to 2011." The young man introduced himself Interestingly, unlike many people's imagination, Chen Qingqi did not come from gardening "I was mainly engaged in sports management, specifically Golf [microblog] management." According to Chen Qingqi, because of his high interest in green turf due to his contact with golf, he finally decided to study turf maintenance in Sweden "Sweden is also one of the best in Europe in this respect." But this time, although the cultivation of turf is completed in the turf maintenance base of the workers' body, there are not so many professional paving technicians Therefore, the workers' body chose to cooperate with Qingdao Saiou company Chen Qingqi, 26, is the commander in chief of the 30 plus paving team The plant protection "export to domestic sale" this time is a warm season grass named "Zoysia chinensis", and the whole laying area is about 8000 square meters "Don't look down on this grass It's a national level II key protected wild plant." Chen Qingqi introduced to reporters Interestingly, although the name contains the word "China", this grass is only recently "exported for domestic sale" "In the past, some sites in the transitional areas of South China and central China were also used, but because the green period of the grass leaves was relatively short, the utilization rate in China was relatively low for the sake of economy On the contrary, Japan, which promoted the rotation of two-season grass, and Australia, which had relatively high temperature, imported the grass from our country in the past, and Japan also carried out genetic improvement This year, we are also the first to try to use it in the work style " National level II key protection of wild plants, so "export to domestic sales" appeared in the workers "According to our plan, 8000 square meters of turf should be paved in three to four days, so all turf can be paved today." Chen Qingqi told reporters in this way Pave 8000 square meters, more than 30 people in only four days, what's the secret? "The secret is preparation for the first three years." Chen Qingqi said so It took three years to cultivate new turf, and the density of root system has been very developed "This time we made a straw roll of 1 meter by 6 meters, which is the first time in China Previously, the cultivation time of domestic turf was short If the straw roll is too long, it is easy to break and break, but this time the turf is very solid, 6 square meters a roll, a total of 1400 rolls, so it will be laid much faster." According to the reporter's observation, every 8 workers in a group can lay a piece of turf in almost a few minutes, which can be said to be very fast When we choose to work in the sun to replace the turf, we also need to choose to work in the sun "If it rains, the large-scale machinery for transporting turf will open on the slippery land, which will lead to the poor flatness of the site Moreover, the sand layer attached to the turf will also lose water in case of rain For this reason, each of our grass rolls is covered with plastic film In addition, because the work body does not have the conditions for long-term preservation of turf, we will transport seven or eight vehicles of turf from the base every day according to the estimated workload, and the rest will continue to be maintained in the base, which is also to ensure the quality of turf to the maximum extent " It is also understood that the joint has been reserved when the turf is cut from the base as a whole, "so we require workers to minimize the gap between the turf when laying, and the joint will not be visible in a few days." "I'd like to see the effect in the stand" the reporter saw on the spot that the previously laid turf close to the north stand has grown very well, and after the laying work is completed, the details work "Now the turf still needs to be pressed, and the pressed turf still needs to be repaired It's OK to cover the small place with sand Those large ones that look darker are retouched in the straw roll, and need to dig a piece of turf for replacement Then it's watering and mending Don't let cats and dogs pee Once they pee, it's over " Chen Qingqi said so "I'm also a fan and I like watching the ball on the spot I'd like to see the effect of this new turf in the sports stand." The post-80s young man said with a smile.
