　　【11】Functional features
　　an is mainly used to regulate the growth of cotton. It can inhibit vegetative growth, strengthen the growth potential of reproductive organs, increase chlorophyll content, enhance photosynthesis, and increase boll setting and boll weight.

　　Cotton  
　　The use time and dosage of cotton adjustment and installation on cotton should be determined according to the seedling situation and soil strength and the weather conditions at that time.
　　① The cotton field is of medium fertility, insufficient stamina, or slow growth in case of drought. It is sprayed with 66.6mg/L chemical solution on the leaf surface at the flowering stage;
　　②The cotton field is moderately fertile, with sufficient stamina and stable appearance. It is sprayed with 66.6~100mg/L chemical solution on the leaf surface at the initial flowering stage (flowering 10%~20%);
　　③The cotton field is rich in fertilizer and water, with good stamina, or there is more precipitation in the middle stage of cotton growth, and it has a long and vigorous appearance. The first regulation is to spray 116.6~166.6mg/L chemical solution on the leaf surface at the full bud stage, and the second regulation is control the spraying of 50~83.3mg/L panpan industry's medicinal solution on the leaf surface from the initial flowering stage to the full flowering stage;
　　④The cotton field has sufficient fertilizer and water, good stamina, large precipitation, large field planting density, and crazy growth. The first control is to spray 150~183.3mg/L chemical solution at the full bud stage, the second is to spray 50-100mg/L chemical solution at the initial flower stage, and the third is to spray 33.3~66.6mg/L chemical solution at the full flower stage according to the field growth.
　　Tomato  
　　At the budding stage of tomato, spraying 60mg/L chemical solution on the leaf surface is beneficial to the healthy growth of tomato, has obvious bud protection effect, and has obvious increment on the number of fruits and the weight of single fruit.
　　【13】Precautions
　　①During the growth period of cotton, the total amount per mu should not exceed 9g.
　　②It is easy to absorb moisture, but does not affect the efficacy.
　　③During storage, it shall be protected from sunshine and rain, and keep good ventilation.
　　④The applicator shall pay attention to safety protection.
