为解决干旱瘠薄地造林成活难的问题,吉铁分局土门岭林场袁嘉慧借鉴菜农覆地膜种菜的经验,进行了油松覆膜直播造林试验。结果表明,覆膜直播造林苗高与苗圃播种苗高相近,平均8—10cm,成活率比植苗造林高15—20%。并可提高穴内土壤温度和
In order to solve the difficult problem of arid infertile afforestation, Yuanjiahui of Tumen Ridge Farm in Ji Tie Branch learned from the experience of planting vegetables in plastic mulch and conducted the afforestation experiment of P. tabulaeformis. The results showed that the seedling height of direct seeding by film mulching was similar to that of nursery sowing with an average of 8-10cm and the survival rate was 15-20% higher than that of plantation and afforestation. And can increase the soil temperature and hole
