2, China's origin is mainly in the northeast, north, northwest, southwest and Guangdong, Guangxi and central China and other provinces and regions are mostly cultivated.
3, Inner Mongolia, Hebei, Henan, Shanxi, Gansu, Shaanxi, Yunnan, Sichuan, Ningxia, Guizhou, Qinghai and other places for the main planting.
Second, the origin of oats environment 1, temperature (1) according to the pulse suitable for growth in a cool climate, but is not cold hardy, the seeds to be in 2-4 ℃ on the germination, seedlings can be -2 to -4 ℃ in the low temperature environment to survive.
(2) In northwestern and northern China, winters are colder, so seeds can only be sown in the spring, and more southerly areas can be sown in the fall, before high temperatures set in.
2, moisture (1) oats grow in the alpine desert area, germination requires a lot of water, the amount of folding is also higher, insufficient moisture during the growth period, will lead to the grain is not full and lower yield.
(2) That is why the rootstocks of oats in general tend to be about 1 meter long so that they can draw more water.
3, soil excellent cultivation, a variety of soils can be planted successfully, but humus-rich moist soil is the most suitable, the amount of acidic soil adaptability is also better.
