Kiwi fruit low-yield orchard soil improvement method

Abstract

The invention discloses a kiwi fruit low-yield orchard soil improvement method. The kiwi fruit low-yield orchard soil improvement method comprises the following steps of digging a circle of annular fertilization ditch at the position 0.8-1.0 m away from a kiwi fruit trunk, obliquely arranging the bottom surface of the fertilization ditch, enabling the depth of an inner side ditch to be slightly higher than a breathing root of a fruit tree, enabling the depth of an outer side ditch to be 5 cm higher than the depth of the inner side ditch, and enabling the width of the ditch to be 30-40 cm; applying a layer of astragalus sinicus powder with the thickness of 2 cm into the fertilization ditch, and backfilling planting soil with the thickness of 2 cm; inserting a plurality of chicken manure rods into the backfilled planting soil and the inner side surface of the fertilization ditch; laying a layer of L-shaped degradable water-absorbing fiber woven mesh, wherein the degradable water-absorbing fiber woven mesh is arranged on the chicken manure rods in a sleeving manner; and applying a layer of orchard waste powder with the thickness of 2 cm, conducting filling and leveling up with planting soil, and applying glycan polypeptide biological potassium. According to the kiwi fruit low-yield orchard soil improvement method, the granular structure of soil can be improved, nutrient elements are activated, the utilization rate of soil nutrients and fertilizers is improved, the nutrient absorption of the fruit tree roots is effectively promoted, and the growth of the fruit trees is promoted, so that the fruit yield and quality of a kiwi fruit low-yield orchard can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement method for low-yield kiwi fruit orchards. Background technique [0002] Kiwifruit is a deciduous perennial vine fruit tree belonging to the Actinidia genus of the Actinidiaceae family. It is a semi-shady plant with strong adaptability and avoids strong sunlight. It is native to the Yangtze River Basin in my country and mostly grows below 2000m above sea level. Kiwi fruit is rich in nutrients, and the total sugar content is 8% to 14%, mainly glucose, followed by fructose. It is also rich in vitamin C, 17 kinds of amino acids, rich in protein and minerals such as calcium, phosphorus, potassium and iron. Because kiwi fruit is comprehensive and rich in nutrition and contains some important substances that are indispensable to the human body, it plays an important role in maintaining human health, preventing and curing diseases, and is deeply loved by cons...
