1、果园覆盖。利用植物的秸秆或塑料薄膜将果树行间、株间地面覆盖,起到保湿防旱的作用。①覆地膜。经调查,栽后盖地膜一般可提高成活率20%左右,发枝数增加45%以上,当年新梢增长30%左右。其方法是:把树盘整成盆状,把整个树盘用聚乙烯薄膜盖严,并使薄膜紧贴地面,在四周用湿土压紧,以防风吹和漏气。②覆草。于早春把树冠下乃至株间、行间用作物的桔杆、杂草、绿肥等有机物覆盖,厚约15—20厘米,可以减少地表水份蒸发,保蓄天然降水,抑制杂草生长。到夏季雨季来临时,结合耕翻,将已腐烂的覆盖物翻入地下,可以增加土壤有机质,改善土壤结构。 2、穴施肥水。穴施肥水能明显的改善旱地果园的营养状况,提高产量。早春在树冠边缘至距树干
1, orchard cover. The use of plant straw or plastic film will be between rows of trees, ground coverage between strains, play a role in moisture and drought. ① cover the film. After investigation, transplanting film generally can increase the survival rate of about 20%, the number of branches increased by 45% or more, when new shoots increased by about 30%. The method is: the tree plate into a basin, the entire tree plate covered with polyethylene film, and the film close to the ground, surrounded by wet soil compaction, to prevent wind and leaks. ② mulching grass. In the early spring under the canopy or even between plants, intercropping crops with straw, weeds, green manure and other organic matter, about 15-20 cm thick, can reduce surface water evaporation, save natural precipitation, inhibit weed growth. By the onset of the summer monsoon season, the combination of tillage and turning the decayed cover into the ground can increase soil organic matter and improve the soil structure. 2, hole fertilizer water. Fertilizer water hole can significantly improve the nutritional status of dry land orchards, increase production. Early spring at the edge of the canopy to the trunk
