作物生长于自然环境中,易受不良环境如干旱、低温、病菌等的影响,作物在一定程度上能通过内因调节,抵抗不良环境,继续生存,成熟时产量和品质不降低或很少降低,这种性能,称抗逆性。我区地形复杂,环境多变,各地均有其特殊的抗逆性问题,这里,只讨论几种较普遍的抗逆性。 Crops grow in the natural environment, vulnerable to adverse environmental effects such as drought, low temperature, germs, crops to some extent through internal regulation, resist the adverse environment and continue to survive, the yield and quality of mature or rarely reduced, This performance, called the resistance. Complex terrain in my area, the environment is changing, all over the country have their own special stress resistance, here, only to discuss a few more common resistance.
