Problems solved by technology

At present, the breeding of medicinal plant seedlings mostly adopts layering treatment, and then the method of raising seedlings in the field or in a facility shed. Since the white tree is a traditional Chinese medicinal material with twigs and leaves, when planted using the traditional method, the trunk of the white tree will stand upright. There are fewer branches, which leads to low yield and poor economic benefits. In addition, when the existing method is used to plant white trees, a large amount of pesticides are required to prevent pests and weeds, resulting in large pesticide residues and heavy metal residues in the medicinal parts of white trees. , seriously affecting the quality of medicinal materials, making the in vitro biological activity of white tree medicinal extracts unstable

Embodiment 1

[0040] Embodiment 1 seedling growth regulation

[0041] The present embodiment provides a kind of method for seedling growth regulation, comprises the steps:

[0042] (1) top growth step: select uniform size, some strains of white tree seedlings with a height of about 10cm, first thin the white tree seedlings to 15cm * 15cm seedling cups, plant 1 seedling in each seedling cup, The seedlings were slowed down outdoors for 5 days, and then transferred to each seedling room in groups. The seedling rack lights were turned on, and the seedling rack lights were used to induce light growth at the top. The daily light time was 12 hours, and the light intensity was 1000xl.

[0043] (2) Side branch growth step: after the seedling grows to 40cm, the top advantage is removed, the seedling raising frame light is turned off and the seedling room light is turned on, and the light in the seedling room light is used to induce side branch growth. The daily light time is 12 hours, and the light i...

[0046] Embodiment 2 seedling growth regulation

[0047] The present embodiment provides a kind of method for seedling growth regulation, comprises the steps:

[0048] (1) top growth step: select uniform size, some strains of white tree seedlings with a height of about 10cm, first thin the white tree seedlings to 15cm * 15cm seedling cups, plant 1 seedling in each seedling cup, Seedlings were slowed down for 5 days, then transferred to each nursery room, the seedling rack lights were turned on, and the seedling rack lights were used to induce the top growth of the light. The daily light time was 12 hours, and the light intensity was 1000xl.

[0049] (2) Side branch growth step: After the seedling grows to 40cm, remove the top advantage, remove the top advantage, turn off the seedling rack light and turn on the seedling room light, and use the seedling room light to induce side branch growth. The daily light time is 12 hours. The light intensity is 800lx.

Abstract

The invention provides a seedling growth regulating method, comprising the following steps of apical growth step: adjusting lighting to induce seedling apical growth, stopping the lighting induction when plant height reaches to 40 to 60 cm under the lighting induction; collateral growth step: removing apical vigor, adjusting lighting to induce seedling collateral growth, and stopping lighting induction for collateral growth after 15 to 30 days of light induction. The invention also provides a planting method of suregada glomerulata, which comprises the seedling growth regulating method; through growth regulation on suregada glomerulata seedlings, the circumferential growth and uniform branching of seedlings are promoted, thus laying a foundation for accelerating plant growth and increasingthe yield of medicinal parts of suregada glomerulata, and effectively improving economic values. In addition, the standardization and industrialization of seedlings are promoted, and compared with the existing seedling growth control methods, no chemicals or hormones are needed, so that the quality and safety of medicines are improved.

Description

technical field [0001] The invention belongs to the field of plant seedling breeding and cultivation, and in particular relates to a method and device for regulating seedling growth and a planting method of white tree medicinal material. Background technique [0002] White tree Suregadaglomerulata (Bl.) Baill., is Euphorbiaceae white tree plant, evergreen shrub or small tree, 2-13 meters high; branches grayish yellow to grayish brown, glabrous. Leaf thin leathery, obovate-elliptic to obovate-lanceolate, 5-16 cm long, 3-8 cm wide, shortly pointed or shortly acuminate at the top, cuneate or broadly cuneate at the base, entire, absent on both sides Hairy, lateral veins 5-8 on each side, petiole 3-12mm long, glabrous. Cymes are opposite to leaves, pedicels and sepals are puberulent or nearly glabrous, flowers are 3-5 mm in diameter when they open; sepals are nearly round, with shallow teeth on the margins; stamens in male flowers are numerous; glands are small, raw At the base...
