地膜覆盖穴贮肥水是山东农大研究的薄地苹果栽培管理的一项技术措施,此项技术投资少,操作简便,易于掌握,效果突出,针对我省的气候、地理及果树生产现状,具有现实的指导意义。现将技术要点总结如下: 一、准备工作。①平整树盘。将树盘按树冠大小套成方形或园形,树盘内保持平整清洁,不要留有枯枝等杂物,以免覆膜时将地膜划破。②施基肥。在头一年秋季施基肥,100-200斤/株,如果秋季没施肥,应在早春补上,也可将有机肥中掺少许磷肥,以提高磷肥的利用率。③地膜和草把。地膜为农用薄膜、厚度为0.02-0.03mm,十年生左右的苹果树每株需4m~2,大树地膜应适量增大;草把用作物的秸秆,也可用其它杂草代
Covering storage and storage of fertilizer is a technical measure researched and cultivated by Shandong Agricultural University. The technique has the advantages of less investment, simple operation, easy to grasp and prominent effect. According to the climate, geography and the production status of fruit trees in our province, it is realistic Guiding significance. The technical points are summarized below: First, the preparatory work. ① flat tree plate. Set the size of the tree by the canopy into a square or a garden, and keep the tree in a clean and flat place. Do not leave debris such as dead branches to prevent the film from being scratched. ② base fertilizer. In the first year of autumn, basal fertilizer, 100-200 kg / plant, if no fertilizer in autumn, should be added in early spring, but also a small amount of organic fertilizer mixed with phosphate fertilizer in order to improve the utilization of phosphate fertilizer. ③ plastic film and grass. Membrane for the agricultural film, the thickness of 0.02-0.03mm, about 10-year-old apple trees need 4m ~ 2 per plant, large trees should be appropriate to increase the plastic film; grass straw used crops can also be used other weed generation
