How to select awnless brome seeds? What are the methods of raising seedlings?

Awnless brome is an excellent forage widely planted in Europe, North America and some countries in Asia, with high nutritional value and high yield. it is the main grass species for the establishment of artificial grassland and environmental protection and sand fixation, and it is an important grass species in Xinjiang and northern China. So how to choose awnless brome seeds? What are the methods of raising seedlings? Let's get to know it.

How to select awnless brome seeds?

The category of awnless brome seed is still very rich, after years of breeding and improvement, there are not a few new varieties, such as Xinque 1 and so on. Among them, the original materials of breeding mainly come from Europe, followed by Asia (China), but there are many awnless brome varieties bred in North America and the planting area is large. The varieties can also be divided into two categories: southern type and northern type, and the varieties suitable for local cultivation can be selected according to the actual production needs.

What are the methods of raising seedlings?

1. Land selection and preparation

The selection of awnless brome is not strict, degraded grassland, converted pasture, hillside grassland, edge gap, forest grassland and so on can be planted. It is more appropriate to plant land with plenty of water and fat around the house and near the enclosure. Before sowing, we should also turn the land deeply to make the land flat and the soil pieces finely broken. It is best to apply basic fertilizer, and those with irrigation conditions should also be irrigated before sowing to ensure soil moisture.

2. Sowing and raising seedlings

There are methods of broadcasting and spreading. Generally, strip sowing is the main method in the field, and the row spacing is 10-15cm. The planter can use a special forage seeder or a general wheat planter. Can also be unicast, but the amount of sowing must be adjusted, sowing depth according to the situation, generally around 2cm for official. According to the soil condition, the sowing rate should be 1.5-2.0kg per mu.

3. Seedling stage management

The growth in the seedling stage is relatively slow, so attention should be paid to weeding and loosening the soil in that year. To promote growth, nitrogen fertilizer should be applied and irrigated once in different stages. After each cutting, fertilizer and irrigation should be applied as appropriate to strengthen the regeneration ability. After growing for 3 years, awnless brome must be renewed and rejuvenated in time because the roots and stems crisscross each other and form turf, resulting in insufficient soil moisture and poor permeability. Before germination in spring or after the first harvest, cut off the rhizome and destroy the turf with a deep pine plough or disc Harrow to promote its vigorous growth.

4. Timely harvest

The stems and leaves of awnless brome are relatively soft and should be harvested during flowering when used as hay. Generally, it is suitable to harvest once, and then harvest twice a year. Autumn harvest should keep 5-10cm to facilitate overwintering.

The above is the introduction of seed selection and seedling raising techniques of awnless brome. I hope it will be helpful to you.
