我区不少生产队,在高粱播种期間,如遇連續阴雨,土壤湿度大、温度低,都有溫湯浸种催芽播种的經驗。生产实践証明:采取这种措施,能避免粉种,提早出苗,保証全苗。高粱粉种是由于土壤温度低、湿度大、空气不足,致使种籽呼吸困难,生活能力降低,丧失发芽能力,加上真菌的侵蝕,种籽发生霉烂而造成的。但經过浸种催芽,种籽本身吸足了水分,处于萌发阶段,由于酶的活动,其中貯藏的物質分解成可溶性的,呼吸作用加强,把养分运轉到生长需要的地方去,因而不良环境条件对种籽本身的影响大大減小,等于提早几天播种,就不致于粉种了。
Many production teams in our region, in the sowing of sorghum, in case of continuous rainy days, soil moisture, low temperature, warm soup soaking germination seeding experience. Production practice has proved that: Take such measures, to avoid powder, early emergence, to ensure that the whole seedlings. Sorghum powder is due to soil temperature is low, humidity, lack of air, resulting in respiratory difficulties, decreased viability, loss of germination capacity, coupled with fungal erosion, resulting in rotten seeds. However, after seed soaking and germination, the seed itself absorbs water and is in its germinating stage. Due to the activity of the enzyme, the stored substances therein are decomposed into soluble and respiration, and the nutrients are transported to the place where growth is needed, resulting in an adverse environment The impact of the conditions on the seed itself is greatly reduced, equal to planting a few days earlier, it will not be powdery.
