[Get up your sleeves and fill in the transcript by yourself] Qinhuangdao's new afforestation technology allows 200,000 acres of old forest farm to "dry wood Fengchun"

On July 29, the reporter walked into the Qilizhuang Forest District of the Guanlin Farm in Beidaihe New District. There were thousands of acres of locust, fragrant flower seedlings in front of the eyes, and the sea breeze swayed like a green wave in the sand dunes, and the trees that were dying and rotten on the top of the head were The tip canopy is in sharp contrast. "These strong young trees are cultivated with broken roots and adorable technology, and the afforestation effect is very obvious." Zhao Zhipo, deputy head of the forest, said excitedly, "This technology has rejuvenated this 200,000 acres of Laulin Farm!"

Tuanlin Farm was founded in the early 1960s. In response to Premier Zhou Enlai's call for "building a state -owned forest farm to make Qingshan often use and benefit future generations", educated youth from all over the country came to this coastal desert. Like the green man in Saihanba, they planted tens of thousands of foreign locusts, elm, and poplars in the 52.1 kilometers of coastal desert belts. Green Great Wall that blocks the tide of storms.

However, after decades of wind and sand erosion, the initial coastal dry forest belt was severely degraded, and the phenomenon of death, dry shoots, and wind could be seen everywhere. The ecological protection function of the forest belt was greatly reduced, and the forest farm supplementary planting was urgent.

In 2011, Tuanlin Farm Innovation Management attracted social capital investment, encouraged large forests to contract forest land, and the government gave certain subsidies. The afforestation achieved significant results. The forest coverage rate increased year by year.

In 2020, the forest farm selected a low -quality forest plot with 700 acres of forests, sparse forests but evenly distributed, and began to perform forest breaks. "We implement mechanical trench roots to promote the natural adorable reproduction update of the locust roots." Sun Shouji, a large household of the afforestation, said, "The shape of the ditch is cone -shaped, the depth of the trench is 30 to 40 cm, the width of the ditch is 50 to 60 cm, and the new reproduction is new. The saplings are both strong, but also greatly reduced the cost of afforestation, and the experiments have achieved great success! "

In Qilizhuang Forest District, the reporter saw that the locust trees breeding with broken roots and adorable technology grew strong, while only dozens of acres of artificial forest trees across the road were less than 1%. "This beach has been planted for four or five rounds. The reason for the low survival rate is because all the soil is fine sand, barren without nutrients, no water preservation, and fertilizer is particularly poor. The method of afforestation is particularly high. "Sun Shouji said.

Zhao Zhipo calculated a account to reporters, taking locust and fragrant locusts with a diameter of 4 to 5 cm. The cost of engineering afforestation is 8,000 to 9,000 yuan per mu. Through the broken roots of the technical afforestation, the cost is only the mechanical fee of the broken roots and the fixed plant fee, which does not exceed 400 yuan per acre, which is one -twenty of the cost of engineering afforestation.

In the past three years, the Tuanlin Farm has adopted more than 4,600 acres of broken roots and adorable technology, saving more than 40 million yuan in afforestation costs.
