Earth ridge for planting young pear trees, and preparation method and application of earth ridge

Abstract

The invention discloses an earth ridge for planting young pear trees, and a preparation method and application of the earth ridge, and relates to an agricultural culture technique. According to wide-furrow narrow ridges provided by the invention, before planting of the young pear trees, soil is subjected to rotary tillage until the soil is level, ridging is performed, the ridge height of each ridge body is 39cm-41cm, the ridge width is 78cm-82cm, the distance between every two adjacent ridges is 400cm-450cm, furrow is formed between every two adjacent ridge bodies, and field planting of the young pear trees having planting distance being 150cm-200cm is performed in the middle of each ridge body; in autumn in the first year of field planting, after rotary tillage of the furrows, the two sides of each ridge body are widened in an equidistant manner until the ridge width reaches 119cm-121cm, and the ridge height is 42cm-43cm; in autumn in the second year of field planting, after rotary tillage of the furrows, the two sides of each ridge body are widened in an equidistant manner until the ridge width reaches 158cm-162cm, and the ridge height is 44cm-46cm; and in autumn in the third year after field planting, after rotary tillage of the furrows, the two sides of each ridge body are widened in an equidistant manner until the ridge width reaches 199cm-201cm and the ridge height is 46cm-49cm. According to the earth ridge disclosed by the invention, the planting fertilizer applying quantity is effectively reduced, besides, abuses of traditional drainage ditches are avoided, the growth quantity of soil layer root systems is increased, and the nematode diseased plant rate and the root knot diseased plant rate are reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for planting young pear trees. Background technique [0002] Pear is one of the fruit tree species with the largest cultivated area in my country, its cultivated area accounts for 73% of the world's total cultivated area, and its total output is 70%. Due to the abundant rainfall in southern my country, pear orchards are built on flat land. Before pear trees are planted, planting ditches are generally excavated along the row direction, with a width of 60cm-80cm and a depth of 60cm-80cm. Dig a 60cm-80cm square planting hole, put the topsoil and base fertilizer in the planting ditch or the lower part of the planting hole, and put the raw soil in the upper part. At the same time, for drainage, a drainage ditch with a width of 40cm-60cm and a depth of 40cm-60cm should be opened to form a wide drainage ditch. Cultivation pattern of ridge and narrow furrow.
