（1）

（2）Classify according to the crop

①Using experiences of fruit trees (apple. peach, pear, cherry, grape, jujube, orange, grapefruit, apricot, plum and so on).

②Using experiences of field crop (wheat, corn, rice, cotton, peanut, bean and so on).

③Using experiences of melon crops and eggplant fruit crops (Cucumber, tomato, pepper, eggplant, watermelon, strawberry and so on).

④Using experiences of leaf vegetables crops (Spinach, celery, Chinese cabbage, lettuce, Chinese Cabbage and so on).

⑤Using experiences of root crops (Onion, ginger, garlic, potato, carrot and so on).

（3）Attentions of spraying

① Foliar spray: avoiding the sunning and raining, should be sprayed again after 6 hours during raining days.

②Using interval should be not less than 10 days

④Dosage should be reduced when spray cucurbitaceae, vitaceae, malvaceae and other sensitive crops in the seedling stage. The spraying concentration should be 3000 times. It’s normal when the leaf is frizzled after spraying. This condition will get well after 2-3 days. Spraying water will be helpful to recover quickly.

②Usage Sequence: first add water, then add foliar fertilizer, wettable powder, suspending agent, aqueous solution and missible oil in turn.

③Seaweed extract belongs to alkaline matter. Complicated chemical reaction will happen when mixed with high concentration of acidic product. Structure and property will be changed, even phytotoxicity will be caused. Usually, avoid to mix with organic phosphorus, organic chloride and missable oil.

④If mixed with un-chelated or un-complexed divalent metal ion (such as copper ion), flocculation precipitation reaction will happen between alginic acid and metal ion.
