How to improve the germination rate of oat seeds

Oat is a kind of food we are familiar with, which has high nutritional value, and many people grow oats, but many farmers do not have professional agricultural technology, so often planting oats has a low seed germination rate. So how can we improve the germination rate of seeds when planting? Let's get to know it.

I. cultivation environment

1. Temperature

Oats like a cool environment, but not cold-resistant, the most suitable for planting in the north, its seeds can germinate at about 2-4 degrees, seedlings can withstand a low temperature of minus 2 degrees, is one of the most cold-tolerant of wheat. In the north and northwest of China, the winter temperature is cold, so it can only be sown in spring, while in the south, the temperature is generally high, which can be sown in autumn and mature before the high temperature in summer.

2. Soil

Under excellent cultivation conditions, oats can get a good harvest in all kinds of soil texture, but the humus-rich wet soil is the best, and its adaptability to acidic soil is stronger than that of other wheat, but it is not suitable for planting in saline-alkali soil.

3. Moisture

Oats are in alpine desert areas, but sufficient water is needed for seed germination, which can not emerge in the period of insufficient water. According to research, oat seed germination requires 65% of its own weight of water. Its transpiration is higher than that of barley and wheat, and it consumes more water. During the growing period, if there is not enough water, the seeds will often grow insufficiently, resulting in a lower yield, so the rhizome of oats will often grow to about 1 meter. In order to absorb more water to grow.

2. Sowing techniques

1. Seed treatment

Oats need to add a sunny and windless environment before sowing, spread the seeds 2-3 cm thick and dry them for 3-5 days, which can promote early seed germination, improve germination rate and emergence ahead of time. It can also use ultraviolet rays in the sun to kill germs on the seed surface and reduce diseases.

2. Sowing time method

Generally, sowing is about 10 cm in soil in early spring, and the best sowing time is around Qingming Festival, which should not exceed Grain Rain at the latest. Mechanical sowing or artificial trenching should be used when sowing, and it is not suitable for sowing. The row spacing of strip sowing is 15-20 cm, and the depth is 3-5 cm. To prevent replanting and missing sowing, the sowing depth should be consistent and the sowing should be uniform. After sowing, the soil and seeds should be closely combined, and the sowing amount should be 10-15 kg per mu.
