Embodiment 1

[0012] The green manure utilization method of Compositae flowers in pear orchards of the present invention includes site preparation, sowing, mowing and covering.

[0013] The technical principle is as follows: firstly, prepare the soil between the rows of pear orchards, clear the stubble and weeds on the ground, plow and harrow it, and then plant Compositae flowers. , 50cm away from the bottom of the pear tree, lightly overturn the soil after sowing, the planting method is simple, no fertilizer is applied during the growth process, and the fruit trees in the pear orchard are managed routinely. During the final flowering period (after the ornamental period), at about the end of July, the aerial parts of the small sunflower seeds and tall stalk cosmos were mowed and covered around the roots of pear trees, and the underground parts remained in the soil. Due to the long flowering period, mow and cover at the end of August. Use the root activity during the growth process to impro...

Abstract

The invention discloses a green manure utilization method for compositae flowers in a pear garden, which comprises the following steps: carrying out soil preparation between rows of the pear garden, removing stubbles and weeds on the ground, planting the compositae flowers after ploughing and raking, performing shallow turning and soil covering after broadcast sowing and conventionally managing fruit trees in the pear garden, wherein a broadcast sowing mode is adopted, the sowing density is 1 kg/mu, the broadcast sowing area is between rows of pear trees and is 50 cm away from the bottoms of the pear trees; and in the final flowering period, cutting the overground parts of the compositae flowers to cover the peripheries of the roots of the pear trees, and reserving the underground parts in the soil. Guizotia abyssinica, coreopsis tinctoria and zinnia elegans are bright in flower color, have high ornamental value and can effectively increase the landscape value of the pear garden in summer when being applied to creation of various landscapes, and due to the fact that the plant height is far lower than that of pear trees, conventional management of the pear garden cannot be affected. Meanwhile, rich nutrients can be provided for soil after cutting, covering and decomposing.

Description

technical field [0001] The invention relates to the technical field of green manure utilization of herbs and flowers, in particular to a method for green manure utilization of Compositae flowers in pear orchards. Background technique [0002] With the development of agricultural science, people are gradually aware of the hazards of excessive application of chemical fertilizers, mainly including soil compaction and soil quality decline. At the same time, with the improvement of material living standards, people pay more and more attention to ecological environment issues, tend to buy ecological food, and travel to rural areas with better ecological environment. Green manure is a crop that can effectively activate soil nutrients, improve soil physical and chemical properties, replace part of chemical fertilizers, reduce soil nutrient loss, improve ecological environment, ensure food security, and provide forage sources. It has been widely used in agricultural production. It c...
