Embodiment 1

[0031] 1. Construction of nursery grounds

[0032] Choose sandy loam soil with loose soil, high humus content, and good drainage as the nursery ground; clean up the original crops and sundries in the nursery ground, plow 20 cm deep in the previous winter, and dry it in the sun after plowing; shallow plowing before sowing, and every Apply 2 tons of fully decomposed farmyard manure as the base fertilizer on the mu of land, spread it evenly and then mix it; rake the well-cultivated seedling land, rake it, and rake it finely, and then spread a layer of seedling substrate with a thickness of 10cm on it. The seedling raising substrate described above is prepared by mixing humus, peat soil, river sand, and pig manure in a mass ratio of 1:3:1:0.5.

[0033] 2. Seed pretreatment

[0034] Select plump and complete Atractylodes atractylodes seeds, soak the seeds in 1000 times liquid of 80% carbendazim wettable powder containing 0.5v‰naphthaleneacetic acid at 30°C for 12h, so that the see...

Embodiment 2

[0042] In step 1 of this embodiment, the seedling-raising substrate is prepared by mixing humus, peat soil, river sand, and pig manure in a mass ratio of 1:3:2:1. Other steps are identical with embodiment 1. Seedlings emerged 15 to 20 days after sowing, and the emergence rate was 87.5%. figure 2 As shown, 2 months after sowing, the seedlings of Atractylodes atractylodis emerged neatly, with few seedling shortages, and the seedling growth conditions were basically the same. The plant height could reach more than 5cm, and there were more than 6 true leaves. The seedlings grow robustly, and the pest and disease rate is less than 5%.

Embodiment 3

[0044] In step 1 of this embodiment, the seedling-raising substrate is prepared by mixing humus, peat soil, river sand, and pig manure in a mass ratio of 1:2:0.5:1. Other steps are identical with embodiment 1. Seedlings emerged 15 to 20 days after sowing, and the emergence rate was 81.7%. image 3 It can be seen that after 2 months of sowing, the seedlings of Atractylodes atractylodis emerged relatively neatly, and in some places where seedlings were missing, the growth of the seedlings was relatively consistent. Most of the plant heights could reach 5 cm and there were more than 6 true leaves. The seedlings grow robustly, and the pest and disease rate is less than 5%.

Abstract

The invention discloses an atractylodes chinensis seed seedling method. The method comprises the steps that sand loam which is loose in soil, high in humus content and good in drainage is selected asseedling land, fully decomposed farmyard manure is applied per mu to serve as base fertilizer, and a mixture of humus, turfy soil, river sand and pig manure is selected as a seedling substrate; meanwhile, atractylodes chinensis seeds are pretreated with naphthylacetic acid-containing 80% carbendazim wettable powder 800-1,200 fold, sowing is conducted from late March to early April, seedlings can emerge 15-20 days after sowing, and the emergence rate can reach 80% or above and up to 95% or above. According to the method, not only can the seed emergence rate be effectively increased, but also the resistance of seedlings is strengthened, and the disease and insect damage rate is lower than 5%.

Description

technical field [0001] The invention belongs to the technical field of planting Atractylodes atractylodes, and in particular relates to a method for raising seedlings of Atractylodes atractylodis. Background technique [0002] Atractylodes lancea (Thunb.) DC.) is a perennial herb of the Asteraceae Atractylodes genus. Distributed in Northeast my country, North China and Anhui, Jiangsu, Shandong, Henan, Shaanxi, Gansu and other places, it is divided into Southern Cangzhu (Mao Cangzhu) to the south and North Cangzhu to the north, taking the Qinling Huaihe River as the boundary. [0003] Atractylodes atractylodis (A.chinensis (DC.) Koidz), is the dry rhizome of Compositae. The plant morphology is basically the same as Atractylodes atractylodes, the main difference is that the leaves are usually sessile, the leaves are wider, ovate or narrowly ovate, pinnately 5-lobed, and the upper leaves are often uncracked with hard spines on the leaf margin; flower heads, involucre The slic...
