Abstract

The present invention discloses an Atractylodes lan-cea(Thunb.)DC. seedling method. The method comprises the following steps of: selecting sandy loam with a high humus content and good drainage as a seedling field; fertilizing uniformly before ridging; deep-rolling soil in early spring, and flattening, wherein the widths of ridges are 1.0-1.2 m, the widths of grooves are 40 cm, and the depths of grooves are 25 cm; mixing 80% carbendazim wettable powder with the using amount of 12g/m(2) and fine earth, and spreading the mixture on seedling beds; selecting full Atractylodes lan-cea(Thunb.)DC. seeds as seedling seeds, soaking with warm water until the seeds are expanded, and soaking with 200 times of biogas slurry for 20-24 h; from the end of March to the beginning of April, digging grooves on the prepared seedling beds under the conditions that row spacing is 20-24 cm, the groove depth is 2-3 cm and sowing quantity is 5-6kg/667m(2), covering the seeds by using fine soil, covering the fine soil by straws, and removing the straws after emergence. The root systems of the seedlings cultured by the method grow well, over 80% of seedlings can achieve: the weight of a single plant is above 3 g, bud points of each seedling is above 6 and the survival rate of transplanted seedlings is above 99%.

Description

RHIZOMA ATRACTYLODIS IANCEAE has drying damp and strengthening spleen; Wines used as antirheumatic; Effect of improving eyesight.RHIZOMA ATRACTYLODIS IANCEAE is China's medicinal herbs most in use simply, have long applicating history, and wild RHIZOMA ATRACTYLODIS IANCEAE is excavated by predatoriness, and resource is increasingly exhausted; RHIZOMA ATRACTYLODIS IANCEAE also has ecological vegetable characteristic, and its nursery is strict to environmental requirement, the environmental ecological benefit that can bring.

Summary of the invention

The present invention aims to provide a kind of RHIZOMA ATRACTYLODIS IANCEAE seedling-cultivating method, to guarantee the seedling individual plant weight more than 3 grams of cultivating, the bud point more than 6 of seedling.

A kind of RHIZOMA ATRACTYLODIS IANCEAE seedling-cultivating method provided of the present invention, comprises the steps:

1 nursery field is selected

Selection humus content is high, and loose, well-drained sandy loam or rotten dregs plot are as nursery field;

2 base fertilizer

Become thoroughly decomposed farmyard manure or barnyard manure, compost, evenly spreads fertilizer over the fields before playing ridge culture railway carriage or compartment;

3 wholely

The early spring, before plantation, shallow plowing, harrowed broken by soil deep tillage 20 1 25cm, and leveling opens railway carriage or compartment, the wide 1.0-1.2m in railway carriage or compartment, furrow width 40cm, ditch depth 25cm, and face, railway carriage or compartment is turtleback shape, the good drain ditch of surrounding;

4 soil treatment

80% carbendazol wettable powder, consumption 12g/m ²mixing fine earth spreads fertilizer over the fields in seedbed;

5 seed treatment

Choosing full rhizoma atractylodis seed is nursery kind, and warm water is dipped into after seed expands, natural pond liquid 200 times of immersion 20-24h;

6 sowings

At the beginning of by the end of March to 4 month, shallow ridges is dug by line-spacing 20-24cm in whole good seedbed, ditch depth 2-3cm, the amount of broadcasting is 5-6kg/667m ², seed and ash are mixed thoroughly, be evenly sprinkled in ditch, lid fine earth 3-5cm, covering 8-10cm straw on it, favourable insulation, moisturizing, be beneficial to seed germination, throws off after emerging.

The seedling root growth adopting said method to cultivate is good, and the seedling of more than 80% can reach: individual plant weight more than 3 grams, and the bud point more than 6 of seedling, seedling transplanting survival rate reaches more than 99%.
