Problems solved by technology

Due to the low temperature in the northern region, short frost-free period, little rain, and dry climate, this seedling raising method uses a large amount of seeds per mu, low seed emergence rate, low seedling survival rate, short growth period, short length of seedlings produced, many branches, and high quality. not guaranteed
Using this seedling for transplanting, the length of the Mongolian Astragalus medicinal material produced is correspondingly shorter, the diameter is thinner, and the yield is low.

Embodiment 1

[0015] (1) Selection of nursery location: In early May 2012, Tavern Village, Deshenggou Township, Wuchuan County, Hohhot City, Inner Mongolia, was used as the nursery base.

[0016] (2) Building a greenhouse: the span of the greenhouse is 8 meters, the bay is 4 meters, the shoulder height is 3.5 meters, the total height is 5.3 meters, and the length is 45 meters. There are two buildings in total, with an area of ​​360m 2 . The main structure is made of cold-rolled hot-dip galvanized pipe, connected by hot-dip galvanized bolts. The three walls in the southeast and west are made of double-layer insulating glass. Ester hollow board, equipped with inner shading heat preservation system, wet curtain fan cooling system, ventilation system, sprinkler irrigation system, etc.;

[0017] (3) Seedbed production: adopt length 100cm, width 80cm, the plastic seedling trough of height 45cm, some air holes are opened at the bottom, and the diameter of air holes is 2mm;

[0018] (4) Soil prep...

Embodiment 2

[0024] Present embodiment 2 and embodiment 1 use the same multi-span greenhouse, and the difference with embodiment 1 comprises:

[0025] (1) Soil preparation for seedling cultivation: select fertile, non-repeatable land soil as seedling soil base material that has removed the surface soil without pathogenic bacteria, turn up the soil, smash the soil clods, remove grass roots and stones, press soil 70%, The ratio of fully decomposed farmyard manure 15% and plant ash 15% is used to prepare seedling soil;

[0026] (2) Seed treatment: Soak the Astragalus mongolica seeds in warm water at 60°C for 24 hours, remove and drain, mix with fine sand, and the ratio of fine sand to seeds is 1:2.5;

[0027] (3) Sowing and raising seedlings: Sow the treated seeds evenly on the seedbed, use 8g of seeds per square meter, cover with 2cm of fine sand, turn on the sprinkler irrigation for 0.5 hours, and then keep the sprinkler irrigation for 0.5 hours every day until the seeds germinate and germi...

Abstract

The invention discloses an astragalus mongholicus bunge greenhouse seedling raising technique. The technique mainly comprises the steps of establishing a greenhouse, manufacturing a plastic seedbed, preparing seedling raising soil, conducting seed pretreatment, conducting sowing and seedling raising, conducting field management, and digging out seedlings for field transplantation. By the adoption of the technique, the emergence rate of seeds can be increased to over 90%, the survival rate of seedlings can reach over 95%, and then seeds are saved; meanwhile, the quality of seedlings obtained is uniform, the lengths of seedlings range from 35 cm to 40 cm, the number of branches is small, and the quality and yield of field transplanted astragalus mongholicus bunge are improved.

Description

Technical field: [0001] The invention relates to the technical field of facility agriculture, in particular to a Mongolian astragalus seedling raising technology. Background technique: [0002] The central and western regions of Inner Mongolia and the northern foot of Daqing Mountain are the authentic production areas of Mongolian Astragalus. The artificial cultivation of Mongolian Astragalus has a certain history and scale, and the method of seedling cultivation and transplanting is often used to plant Mongolian Astragalus. One of key links of seedling raising and transplanting method is seedling raising, and the seedling raising method that adopts at present is traditional field seedling raising, carries out seeding seedling raising in early May every spring, digs seedling and transplanting in April of the following year. Due to the low temperature in the northern region, short frost-free period, little rain, and dry climate, this seedling raising method uses a large amoun...
