Improper application of chlorinated fertilizer may cause burning, injury, etc. In the specific application, the following aspects should be noted:
1. Chlorinated fertilizer should be applied preferentially to crops with high chloride tolerance or moderate chlorine tolerance, such as rice, wheat, rape, spinach, radish and tomato; for crops with weak chlorine tolerance, such as tobacco, tea, lettuce and grapes Etc., generally do not apply or less.
Second, the chlorinated fertilizer is suitable for application in rainy seasons or areas with high precipitation; dry land without irrigation conditions, saline-alkali land with poor drainage, high temperature and dry season and areas with less precipitation are best not applied or less.
Third, when applying the chlorinated fertilizer, combined with the application of fully decomposed organic fertilizer, the fertilizer effect of the chlorinated fertilizer can be improved, and the adverse effects caused by the chloride ion can be alleviated.
Fourth, containing chlorinated fertilizer can be used as base fertilizer or top dressing, not suitable for seed fertilizer. It can be applied in the middle and late stages of crop growth, and should be applied less or not at the seedling stage.
