蔬菜种子的寿命越长,在生产上可利用的年限越长,可以减少良种繁殖耗费的人力、物力。怎样才能延长种子寿命和利用年限? 据调查了解,影响蔬菜种子寿命的内在因素是种子营养状态。从受精到种子成熟期间,植株显著缺氮、磷、钾、钙等营养因素,植株上采收的种子,发芽率会迅速下降。其呼吸强度也有影响。未成熟的种子由于含水量高,呼吸强度大,消耗养分多,因此其种子寿命也较短。
The longer the life of vegetable seeds, the longer the production available, can reduce the cost of man-made and material resources. How to extend seed life and useful life? According to the investigation, the intrinsic factor that affects the life of vegetable seeds is seed nutrition status. From fertilization to seed maturity, the plant significantly nitrogen, phosphorus, potassium, calcium and other nutritional factors, plants harvested seeds, germination rate will decline rapidly. Its respiration intensity is also affected. Immature seeds, due to their high water content, high respiration intensity, and high nutrient consumption, have a shorter seed life.
