How to select the seeds of Amorpha fruticosa? What are the methods of raising seedlings?

There are a variety of flowers and trees in nature. I don't know what kinds of trees we all know. Today, Xiaobian mainly talks about Amorpha fruticosa. Although it has certain toxicity, it also has many medicinal effects and can treat a variety of diseases. How do you select seeds? What are the breeding methods? Friends who want to know quickly read the following!

How do you select seeds?

Amorpha seeds should be selected quality clearance, full particles, do not be greedy for cheap and buy poor quality seeds, to go to the local specialized seed sales mall to buy, if there is no suitable local place, you can also buy from our agricultural news network here.

2. The seedling raising method of Amorpha fruticosa seeds

1. Overview of nursery land

Nursery ground is located in Maanshan vegetable garden, located in the middle of Songnen Plain. The geographical coordinates are 124°35′ E, 44°40′ N, 126m above sea level, annual average temperature 3.8℃, annual precipitation 430mm, frost-free period 120~150d, soil texture of seedling site is loam.

2. Seed collection

The seed collection of Amorpha fruticosa is to select the excellent mother plant with strong growth and no diseases and insect pests for seed collection. The fruiting period is 9~10 months, the pod is elliptic, slightly curved, brown when mature, containing 1~2 elliptic or long kidney shaped seeds, smooth, yellow-green, hard seed coat.

3. Seed treatment

Purple ear pod pericarp contains oil, seed hard, hard more, not easy to absorb water permeability, germination slow. In order to make the seedlings emerge neatly, shorten the emergence period and improve the germination rate of seeds, seeds must be treated.

4. Soil preparation and bed making

Amorpha seedlings have the ability of drought resistance and waterlogging resistance, but the soil conditions are not strict, but in order to cultivate strong seedlings in production, we choose flat terrain, good drainage, convenient irrigation, deep soil, more fertile vegetable garden as sowing land. Deep ploughing of 30cm shall be carried out in autumn of the year before sowing to fully weather the soil layer. Before sowing in early April of the next year, careful soil preparation shall be carried out, sufficient base fertilizer shall be applied, 1500~ 2000kg of fully decomposed organic fertilizer and 15k compound fertilizer shall be applied every 667m2, shallow ploughing and leveling shall be carried out to make a flat bed with width of 1.2m and length of 10m. In the north-south direction, the bed surface shall be flat and the soil shall be finely divided.

5. Sowing

One day before sowing, the bed surface was watered with bottom water, and then 1 part of quintozene and 1 part of zinc were poured into a spray pot, stirred fully, and sprayed on the bed surface every 667 m2 10 g to disinfect the soil. On the second day, trenching and wide sowing were adopted to make seedlings receive light evenly. The furrows were 2~3cm deep, 10cm wide and 20cm in row spacing. After ditching, level the bottom of the ditch with your feet, evenly sprinkle the seeds into the ditch, cover the seeds while sowing (sifted fine soil), the thickness of the soil should be 1~1.5cm, and the thickness should be uniform to facilitate neat emergence. Water enough, cover with straw curtain in time, keep the soil moist, remove the straw curtain in time after 60% of seedlings are unearthed.

6. Seedling management

(1) Thinning

When the seedlings are 3 - 5cm high, remove the plant diseases and insect pests seedlings, thin seedlings and dense twin-plant seedlings, and remove the inferior ones and keep the superior ones. When the seedling height is 6~8cm, the seedlings are thinned for the second time, and the density is removed to achieve moderate density and uniform distribution, so as to facilitate ventilation and light transmission and promote the growth and development of seedlings.

(2) Watering

Amorpha seed about a week to start germination, such as bed soil drought before emergence, to timely watering, do not irrigate the head water. After each thinning seedlings should be watered in time to prevent seedling root ventilation. The bed soil is not easy to be too wet, so as not to cause excessive growth of seedlings or disease. At the early stage of seedling growth, the above-ground part and root system of seedlings began to grow and form root system, but the distribution was relatively shallow, such as insufficient water in bed soil, which easily caused seedling death. At this time, to keep the surface bed soil often moist, increase the amount of watering appropriately, and the number of watering times can be reduced accordingly. From the fast-growing period of seedlings to the fast-growing end, the seedlings grow fast and require more water, which can be taken less and more to fully meet the water required for rapid growth of seedlings. Seedling growth later, in order to prevent excessive growth of seedlings greenery, so that seedlings fully lignification, should stop watering.

(3) Topdressing

After emergence of seedlings to the initial stage, spray 1~2 times of big fertilizer, the concentration of 0.1% is appropriate. Urea was applied 1~2 times at the fast-growing stage, phosphorus and potassium were applied 10kg/667m2 to prevent excessive growth of seedlings and promote sufficient lignification of seedlings. At the later stage of seedling growth, topdressing should be stopped to promote sufficient lignification of seedlings and ensure safe overwintering of seedlings.

(4) Intertillage and weeding

After the seedlings come out, loosen the soil and weed in time. When weeding, try to pull them out by hand to prevent injury. During the seedling growth period, about 3~4 times of intertillage and weeding are carried out throughout the year. Keep the soil loose and prevent weeds from competing with seedlings for water and nutrients. Amorpha very few diseases and insect pests occur, once occurred, to use pesticides and fungicides in time to prevent and control, to prevent spread.

Well, today Xiaobian to share with you the content of this first, if you also intend to plant amorpha, then choose the seeds to try to be of high quality, it is recommended not to covet cheap to buy some inferior. The above small series also shared with you in detail the relevant Amorpha seedling methods, hoping to help you.
