Sowing and seedling growing method of Allium victorialis

Abstract

The invention discloses a sowing and seedling growing method of Allium victorialis. The method comprises the following steps that seeds are collected around the midmonth of July each year, and sown immediately after collection and before 15th, July at least; a flat underwood or forest edge area rich in humus is selected for furrowing, and the light transmittance of the underwood area needs to reach 50-55%; 15 cubic meter of decomposed pig or cow manure is applied in each mu, deep plouging is carried out land selection and fertilizing, furrowing is carried out according to the ridge surface width of 90-120cm and field drain width of 40cm, and the height of furrows is 15cm; and broadcasting or furrow sowing is carried out, the sowing amount is 40g / m2, furrows in the width of 10cm and the line spacing of 10cm are formed for furrow sowing, 0.8-1.0cm of soil is covered after sowing, then 2.0-3.0cm of pine needles or straws are covered, 2ml of 40% phoxim missible oil added with 2kg of wateris fertilized in each square meter, and reasonably management after sowing is implemented. Seedling emergency time of seeds of the Allium victorialis is changed from 3 years to 2 years, and the problems in seedling growing in main Allium victorialis producing areas in Jilin and Heilongjiang provinces can be solved.

Description

technical field [0001] The invention relates to the field of plant seedling cultivation, in particular to a method for seedling cultivation of shallots. Background technique [0002] Allium victorialis L. is a perennial herb of the genus Allium lily, widely distributed in the northern temperate zone. In the Northeast, the onion is distributed in the shady slopes of the Changbai Mountains at an altitude of 500-1000m. At present, a small amount of distribution is found in Dunhua, Changbai, Antu and Liaoyuan areas of Jilin Province, and a little more is distributed in the Greater and Lesser Khingan Mountains of Heilongjiang Province. However, due to the high demand in the export market, the wild resources in the two provinces are almost exhausted. [0003] In order to protect wild resources, artificial cultivation has been carried out in many areas in recent years. The main form is to dig wild plants back to plant at home, and then carry out asexual or sexual reproduction. T...

AI Technical Summary

Problems solved by technology

The reproductive coefficient of asexual reproduction is small, which cannot meet the production requirements

And at present sexual reproduction (seed propagation) mostly adopts the mode of autumn sowing or spring sowing seedling raising of common crops to carry out, after sowing, only long root does not appear out of seedling in the second year, and most peasant household thinks that seed can not emerge and abandons or abandons the management of nursery land instead lead to seedling failure

Even if there are a small number of farmers who strengthen management, the seeds they sow will not emerge until the third year after the seeds are collected; at the same time, in terms of sowing technology, due to the small amount of sowing and the low density of seedlings, the labor required for weed control during seedlings is large. It also often leads to unsuccessful breeding
