Multi-layer interplanting method for day lily

Abstract

The invention discloses a multi-layer interplanting method for day lily. The method adopts a three-layer circular interplanting mode; in a first-layer field, interplanting is performed in a three-dimensional growing environment with an upper plant of lily and a ground plant of medlar, each two lines of lily are interplanted with two lines of day lily therein, and the two lines of day lily are interplanted with a line of medlar therein; in a second-layer field, cedrela sinensis is planted as the upper layer, each two lines of cedrela sinensis are interplanted with two lines of day lily therein, and the two lines of day lily are interplanted with a line of tea-oil trees; in a third-layer field, azalea is planted as the upper layer, each two lines of azalea are interplanted with two lines of day lily therein, and the two lines of day lily are interplanted with a line of India wormwood herb therein; the planting area of each layer is 2-4 mu, an interlayer vertical drop height is 2-4 meters. According to interplanting mode of the method provided by the invention, a survival rate of day lily seedlings can be greatly improved, geographical conditions and photo-thermal resources are fully utilized to perform up-down interplanting, a utilization rate of lands is improved, and economic benefit is increased.

Description

technical field [0001] The invention belongs to the technical field of tree cultivation, and in particular relates to a multi-layer interplanting method of day lily. Background technique [0002] Honey locust, also known as honey locust tree, saponins, etc., belongs to Rosaceae, leguminous deciduous trees or small trees, the leaves are pinnate compound leaves, 10-18 (26) cm long; the small petioles are 1-2 (5) long mm, pubescent. Flowers polygamous, yellow-white, many seeds, oblong or oval, 11-13mm long, 8-9mm wide, flowering period March-May; fruit period May-December. [0003] Acacia fruit is a natural raw material for medicine, food, health products, cosmetics and cleaning products. In addition, acacia seeds can digest food and appetizers, and contain guar gum; acacia thorns (soap needles) contain flavonoid glycosides, phenols, and amino acids, which have high economic value. Acacia seeds are rich in galactomannan gum and protein components, and galactomannan gum is us...

AI Technical Summary

Problems solved by technology

Honey locust beans are rich in crude protein and polysaccharides, and the oil content exceeds that of soybeans. The traditional method of cultivating honey locust trees is relatively simple. Only planting honey locust trees will cause serious damage to weeds in the garden, and the cost of weeding and fertilizer input is high. The land utilization rate is relatively low, which affects the planting benefits of saponins. Now we provide a kind of multi-layer interplanting, and the economic crops of various medicinal materials are planted in layers, which effectively reduces the damage of diseases and insect pests, and greatly improves the survival rate of day lily seedlings. Using geographical conditions and light and heat resources, intercropping between high and low crops has been implemented, which has improved land utilization and increased economic benefits
