Problems solved by technology

However, the introduction of willow willow to central Yunnan found that the germination rate of its seeds at room temperature after maturity is extremely low, only about 7.00%, which directly affects the effect and efficiency of willow willow in ecological restoration. At present, it is urgent to solve how to improve The germination rate of willow willow seeds saves germplasm resources and greatly improves the effect and efficiency of its application in ecological restoration in central Yunnan

Embodiment 1

[0018] 1. Seed harvesting:

[0019] During the seed maturity period from late September to late November every year, use branch shears to cut off the fruiting branches with seeds directly, and collect them together and bring them back indoors; after harvesting, remove the peels, twigs and other impurities in time, and keep the color of the seed coats black seeds;

[0020] 2. Seed screening and drying:

[0021] The harvested seed coat color is black and willow willow seeds are screened with 3 times the volume of tap water, and the seeds floating on the water surface are discarded after 10 minutes, and the remaining seeds that sink to the bottom of the container are mature and plump seeds, which are selected and placed in Air-dry for 48 hours at room temperature for later use. During the air-drying period, manually remove the seeds with insect eyes;

[0022] 3. High temperature treatment:

[0023] Use a constant temperature drying box to set the temperature in the box to 80°C...

Abstract

The invention discloses a treatment method for improving the germination rate of willow willow seeds, which relates to the technical field of plant seed seedling raising, and its specific steps are: (1), seed harvesting; (2), seed screening and air-drying; (3) , high temperature treatment; (4), seed germination. The method is simple and easy to operate, low in management cost, simple in technical requirements, easy to popularize and apply, and can be widely used in the engineering technology of slope willow seedling raising and slope ecological restoration and control.

Description

Technical field: [0001] The invention relates to a treatment method for improving the germination rate of willow willow seeds, belonging to the technical field of plant seed seedling cultivation. Background technique: [0002] Poliu ( Dndonaea viscosa L.) Also known as car mulberry and bright oil seed, it belongs to Sapindaceae (Sapindaceae) car mulberry genus ( Dodonaea Miller) is a perennial evergreen shrub or small tree, often born in dry hillsides and open fields, distributed in tropical and subtropical regions all over the world, mainly distributed in the southwest, south to southeast of my country, and often forms a variety of typical groups in dry and hot valleys Cong landscape. Its root system is very developed, it has strong drought and barren tolerance, and has the characteristics of strong germination ability. It is often used as an important vegetation restoration species in arid and semi-arid areas. However, after the introduction of willow willow to centra...
