Ditch grass ridging, drainage and root-raising method in apple orchard

Abstract

The invention relates to a ditch grass ridging, drainage and root-raising method in an apple orchard. The method comprises the following steps of: digging 4-6 radial ditches from the position being away from a trunk about 40cm to a row middle till a row middle drainage ditch before a rainy season, wherein the width and the depth of each radial ditch at the end which is close to the trunk are 20cm respectively, the width and the depth of each radial ditch at the end which is close to the drainage ditch are 40cm respectively, crop straw (which keeps the original shape and is not crushed) is placed in the ditches, one layer of straw and one layer of soil are alternately placed, and 50-100g of urea or 1000-2000g of commercial biological organic fertilizer is applied in each tree; and finally covering the redundant soil below a tree packing in the shape of a steamed bun. The occurrence of waterlogging damages of apple trees can be effectively prevented by adopting the method; and simultaneously, a root zone of each tree can be optimized, the vitality of a root system of each tree can be improved and early leaf fall can be prevented.

Problems solved by technology

Apple is a plant with poor waterlogging tolerance. After waterlogging, it will cause yellowing of leaves and fruit drop. In severe cases, it will cause root system death and cause dead trees, low economic yield and poor quality.

According to survey statistics, as many as 30% of the orchards in Shandong Province suffer from waterlogging during the rainy season every year, causing huge economic losses to local fruit farmers. This is also a major problem that plagues the current high-quality and efficient production of orchards
