Method and application for preventing garden weeds

Abstract

The invention discloses a method and application for preventing garden weeds and belongs to the technical field of garden plantation. A forest spare land is employed for plantation of one or a plurality of types of annual or perennial wild vegetables. Broadcasting, transplantation, fertilizer application, intertillage weed control, pesticide application and harvesting are manually managed to promote population advantage conversion and gradually form advanced population for wild vegetables, so wild vegetables and weeds growth can be controlled or prevented. By the use of the method, harvest can be conducted for many times with one time plantation, so labor work and time use can be reduced and efficiency can be improved; a certain promotion and guide role is played during agricultural production; and the method and application is suitable for garden wild vegetable plantation and garden weed removal.

Description

technical field

[0001] The invention relates to a method and application for controlling weeds under garden trees by utilizing dominant populations, and belongs to the technical field of garden planting. Background technique

[0002] With the acceleration of urbanization in my country and the rapid development of garden planting bases, there are problems of continuous cultivating and weeding in the daily management of garden planting, which is labor-intensive and time-consuming, and limits the improvement of benefits. Common methods of weed control in gardens and green spaces include physical control methods, such as manual weed removal, and chemical control methods. Pulling weeds manually requires a large investment and is labor-intensive and time-consuming. Although chemical weeding can reduce labor intensity, it can effectively control the contradictions between field weeds and crops competing for glory, fertilizer and water. However, due to the excessive application of...

Examples

Embodiment 1

[0019] Embodiment 1: Deciduous arbor undergrowth planting pattern

[0020] Planting of privet

[0021] 1. Plant privet saplings with a DBH of 6 cm. Ridge and make a bed according to the distance between the plants and rows of 3×3m, and excavate the tree holes. After the planting of Ligustrum large-leaf, normal management, watering, fertilization, cross-cutting and spraying and pre-winter protection are carried out.

[0022] 2. Planting and management of Ophiopogon japonicus

[0023] Ophiopogon japonicus likes dampness, drought tolerance, and strong cold tolerance. The soil requirements are not strict, and it is better to be moist and fertile. The Yangtze River Basin is evergreen all year round, and the Yellow River Basin can survive the winter in the open.

[0024] Propagation and Cultivation: Propagation by division is the main method, and it can also be propagated by sowing. Propagation by ramets should be carried out in spring from March to April. Ridges were raised be...

Embodiment 2

[0027] 1. Field management of wild shepherd's purse

[0028] The furrow surface should be fine, flat and soft. The furrow is 2 meters wide, high and flat, to facilitate watering and drainage. Shepherd's purse is usually sown. Spring sowing requires 1.5-2.0 kg of seeds per acre, and summer sowing requires 2-2.5 kg. Combined with processing and sales conditions, the sowing period of shepherd's purse or bitter cabbage should be reasonably extended and the sowing density adjusted. The seedlings can be collected in 5 to 7 days after spring sowing; the seedlings can be collected in 3 days after sowing in summer and autumn. Before emergence, it is necessary to water frequently with small water to keep the soil moist to facilitate emergence. Pay attention to proper irrigation after emergence and keep it moist.

[0029] For the shepherd's purse cultivated in spring and summer, due to the short growth period, it is generally topdressed twice. The first time is when there are 2-3 tru...
