用预洒水来减轻水稻潮风害的模拟试验研究

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。

Simulation Experiment Research of Mitigation of Salty Wind Damage on Rice Through Previously Sprinkle Water

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 reduced 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.
