Description

A kind of seedling raising method of divine soybean seed

technical field

The invention belongs to the field of agriculture and forestry planting, and in particular relates to a seedling raising method of Shensoy bean seeds.

Background technique

Cassia agnes, also known as realgar beans, row money beans, disintegration, "spotted flowers" in Jingpo language, belongs to the perennial woody plant of the hemataceae (Caesalpiniaceae) Cassia L. The southern foot of the prison mountain. The branches of Shensoybean are stretched, the crown is as wide as an umbrella, and the pinnate leaves are dense and green. Flowers are axillary and form corymbs-like racemes. The flowers are red or light red, fragrant and beautiful. The flowering period is from early March to early June, and the flowering period is three months. In autumn and winter, the long cylindrical pods hang like sausages. It is a landscaping tree flower with high ornamental value. Field investigation found that the natural distribution of Shensoybean grows well, but its natural regeneration ability is poor, and there are no seedlings and saplings under the tree.

Because the endocarp of Shensoy bean fruit wraps the seeds in a membranous shape, resulting in poor water permeability of the seeds, the natural germination of Shensoy bean seeds is extremely difficult and the emergence rate is very low. At present, relevant researches have been carried out on the seed germination of Shensoy bean, for example (Zeng Lei et al., The seedling raising method of Shensoy bean, 2002, 18(2): 19 Guangdong Forestry Science and Technology) There is a seedling raising method, but the seedling raising method is mainly concentrated sulfuric acid seed treatment The method is different from the seed treatment and seedling raising method applied in our actual production.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a seedling raising method of Shensoy bean seeds that can improve the germination rate, so as to solve the problem of difficult germination of Shensoy bean seeds, the germination rate can reach more than 85%, and the survival rate of the seedlings is high.

To achieve the above object, the present invention has adopted the following technical solutions:

A method for raising seedlings of soybean seeds, comprising the following steps:

After peeling, the mesocarp is gray-green, which can be peeled into single grains, which are mature fruits. The exocarp and mesocarp of the cylindrical fruit are struck with a blunt instrument until the seeds are peeled off;

(2) Disinfection: seeds are disinfected by soaking in 0.2% potassium permanganate solution for 1 hour, then rinsed with clean water, spread out and air-dried for use;

(3) Seed treatment: take the seed hilum as the midline of the air-dried seeds, and cut the seed coat with sharp scissors on the left or right side of the seed hilum, but it is advisable not to damage the endosperm;

(4) Seed soaking and swelling: put the broken seeds into clean water, and remove inferior seeds floating on the water surface by water selection method; soak the remaining seeds in clean water for 48 hours at room temperature, and change the water every 12 hours, when the seeds absorb water and swell 1.5 times, and sow when the wrapping of the membranous endocarp is completely removed;

(5) Sowing according to bag seedling on-demand or seedbed sowing.

Preferably, in step (4), mix well with carbendazim wettable powder with a concentration of 50% in a concentration of 0.2%-0.3% by weight of the seeds before sowing.

Preferably, in step (5), the on-demand bag seedlings are watered with pre-installed nutrient bags, and 8 hours before on-demand sowing, 50% carbendazim 500 times liquid nutrient bags are used for soil disinfection, and then the seed dressing Soybean seeds are sown in each bag on demand. When sowing, the hilum is parallel to the soil and the hilum faces south. The depth of sowing is 1cm-1.5cm. After sowing the seeds, keep the soil in the bag at a suitable humidity, which is conducive to seed germination. %-70% sunshade net to prevent seedlings from being burned; 3-5 days after sowing, the seeds germinate and unearth, after 21 days the first pair of true leaves unfolds, every 7-10 days, spray 50% wettable carbendazim 500 times liquid or evil Mieling 3-5 times of management.

Preferably, in step (5), the seedbed sowing method is that the seedbed size is 100cm×20cm, and the seedbed is irrigated with 3000 times liquid of 96% oxamixil to make the liquid fully penetrate deep into the soil, and after 8 hours, 400g of seeds are sown. /m ² , the thickness of seed covering soil is 1cm-1.5cm, water it with a watering can, buckle a 100cm×80cm arch shed, cover the arch shed with a 60%-70% shading net, keep the soil moisture of the seedbed, and the seeds germinate 3-5 days after sowing Unearthed, the first pair of true leaves grows in 21 days and the survival rate is high. After the seedling stage of Shensoybean for 21 days, every 7-10 days, spray 500 times of 50% wettable carbendazim or oxamyl 3-5 times care.

Beneficial effects: compared with the prior art, the present invention has the following advantages: high seedling emergence rate, simple maintenance mode and low cost. According to local conditions, the two sowing methods have high applicability.
