摘要：

为了大幅度减少因潮风害造成的水稻生产损失，提出了应用预洒水-洒水来减轻潮风害盐分影响水稻的方法，并用模拟实验比较了经过预洒水-洒盐水-洒水的水稻和仅进行洒盐水-洒水的水稻的1穗盐分量的差别。结果表明，当洒盐水使得1穗盐分量为4.6~4.8 mg/穗时，预洒水-洒盐水-洒水的1穗盐分量为0 mg/穗，洒盐水-洒水的1穗盐分量为2.8 mg/穗，即有预洒水的比无预洒水的能大幅度减小1穗盐分量，从而大大减轻潮风害的影响。还开发了用海水盐度检测仪来测定1穗盐分量的实用测定技术，并提出了减轻水稻潮风害的综合方法。

Abstract:

To drastically reduce the loss of rice production caused by salty wind damage, we made an investigation to the effects of pre-sprinkling water on salty wind damage. The amount of NaCl adhesion per panicle was compared between treatments with pre-sprinkling water - sprinkling salty water - sprinkling water and sprinkling salty water - sprinkling water by simulation experiments. When sprinkling salty water produced 4.6-4.8 mg of NaCl adhesion per panicle, the treatment with pre-sprinkling water - sprinkling salty water - sprinkling water produced 0 mg of NaCl adhesion per panicle while sprinkling salty water-sprinkling water could produce 2.8 mg of NaCl adhesion per panicle. This results indicated that, pre-sprinkling water could effectively reduce the damage of salty wind damage. In addition, we developed a technique to measure the amount of NaCl adhesion per panicle by refractometer and put forward a comprehensive system to alleviate the salty wind damage.
