Embodiment 1

[0053] A method for compound planting of leguminous arborescens based on allelopathy, the steps are as follows:

[0054] ⑴ After the leaves of the pagoda tree fall in autumn, keep the fallen leaves and decompose them without tillage;

[0055] ⑵In the spring of the second year, plow the fallen leaves of Sophora japonica covering the surface into the soil for natural decomposition;

[0056] (3) After 3 months of full maturity, that is, at the beginning of June, directly sow the seeds of leguminous crops in the open space between the rows of Sophora japonica, and then irrigate.

[0057] Preferably, the leguminous crop seeds in the step (3) are sweet-scented clover seeds and / or alfalfa seeds and / or soybean seeds and / or mung bean seeds and / or black bean seeds.

[0058] Preferably, the Chinese pagoda tree is a deciduous tree, a leguminous tree species, and has an allelopathic effect.

[0059] Preferably, the leguminous crop has rhizobia, can fix free nitrogen in the soil, improve ...

Embodiment 2

[0081] A method for compound planting of leguminous arborescens based on allelopathy, the steps are as follows:

[0082] ⑴ After the leaves of the pagoda tree fall in autumn, keep the fallen leaves and decompose them without tillage;

[0083] ⑵In the spring of the second year, plow the fallen leaves of Sophora japonica covering the surface into the soil for natural decomposition;

[0084] (3) After 3 months of full maturity, that is, at the beginning of June, directly sow the seeds of leguminous crops in the open space between the rows of Sophora japonica, and then irrigate.

[0085] A method for verifying the above-mentioned allelopathic-based compound planting method of leguminous arbor and grass, the method includes the collection of littered leaves of Sophora japonica in the same year and the preparation of leguminous crop seeds, the preparation of the extract of fallen leaves of Sophora japonica, indoor Germination test, seed germination, seedling growth observation and ...

Abstract

The present invention relates to an allelopathic compound planting method of leguminous arborescens, the steps are as follows: (1) After the fall of Sophora japonica in autumn, keep the fallen leaves and decompose them without tillage; (2) Wait for the next spring, and then Plow the fallen leaves of Sophora japonica covering the surface into the soil for natural decomposition; (3) After 3 months of full maturity, that is, at the beginning of June, directly sow the seeds of leguminous crops in the open space between the rows of Sophora japonica, and then irrigate, that is, Can. Methods Through the compound planting of trees and herbs, the mutual benefit cooperation between trees and grasses can not only make full use of space and resources, but also improve the soil structure, increase land output, and increase farmers' income; The method is to sow the seeds of herbal crops directly under the pagoda tree. It is highly feasible, practical, easy to operate, efficient, labor-saving, low cost, and suitable for large-scale promotion. It is an effective way to make full use of space and land resources. method.

Description

technical field [0001] The invention belongs to the technical field of arrangement of trees, shrubs and grasses, in particular to an allelopathy-based compound planting method of leguminous trees and grasses and a verification method thereof. Background technique [0002] The agroforestry system is a land use and management system that artificially combines woody plants with other cultivated plants (crops, medicinal plants, economic plants, fungi, etc.) in time and space in a land use unit. Improve land utilization, prevent pests and weeds, achieve high and stable yields, and improve the ecological environment and maintain ecological balance. [0003] The classic mixed hybrid theory often focuses on considering the mechanical, biological, physiological and ecological interactions between tree species and individuals, while ignoring biochemical effects; when selecting tree species, only pay attention to the yin and yang of tree species, the depth of roots, and the broadness o...
