果园长期使用化肥,不注意有机肥的使用,造成果园土壤板结、理化性状失调。要解决这一问题,可坚持覆盖黑地布、草帘。1)覆盖作用。挂果园株间覆黑地布,行间覆草帘的作用:一是保水、保肥、保墒;二是春季提高土壤温度,促使果树根系提早生长;三是熟化土壤,提高土壤有机质含量。2)材料选择。(1)黑地布。应选择质地较密、厚度0.09cm、宽度1~1.2m的黑地布,每卷25kg,每亩用1卷。(2)草帘。要求用稻秆为原料,厚度10cm,宽度1.2m,长度12~15m,每亩用15卷。
Orchard long-term use of chemical fertilizers, do not pay attention to the use of organic fertilizer, resulting in orchard soil compaction, physical and chemical properties disorders. To solve this problem, you can insist on covering black cloth, straw curtain. 1) Coverage. Hanging orchards between the black soil covered cloth, the role of grass covered with curtains between the line: First, water, fertilizer, moisture; second is to raise soil temperature in spring to promote early root growth of fruit trees; the third is maturation of soil, increase soil organic matter content. 2) Material selection. (1) black cloth. Should choose a dense texture, the thickness of 0.09cm, width of 1 ~ 1.2m black cloth, each roll of 25kg, with 1 volume per mu. (2) straw curtain. Requirements of rice straw as raw material, thickness 10cm, width 1.2m, length 12 ~ 15m, with 15 volumes per mu.
