Application of Plant Growth Regulator in Strawberries

- Jan 17, 2018 -

1. Increase yield

Naphthalene Acetic Acid. Spray Young fruit with 10-50mg/l naphthalene acetic acid solution, which can promote fruit expansion and increase yield.

2.4-D. Spray Young fruit with 10-50mg/l 2.4-D solution, which can promote fruit expansion and increase yield.

Indole Acetic Acid. Spray Young fruit with 10-50mg/l Indole acetic acid solution, which can promote fruit expansion and increase yield.

2. Keep Fresh

Cytokinin. After harvesting the strawberries, spray the fruit or leach with 10mg/l cytokinin. When it is dry, put it into a shallow basin. The amount of 200 to 500g per box can keep strawberries fresh and prolong storage time.

Vitamin. The strawberries were soaked for 3 to 5 hours before sowing, and then the seeds could be seeded when they became dry, which can promote rapid germination of the seeds. At the time of seedling, spray 2 to 3 times every 5 to 7 days with 1000 times fluid, which will make the strawberry seedlings more robust. Each 1.5 mu add 0.5 to 1kg vitamins and then mixed with fertilizer to soil, which can increase soil vitality. After the transplanting, spray leaves or irrigation root once every 5-7 days with 1000 times Vitamin solution and 0.1%-0.3% urea, so as to prolong the harvest time.

3. Promote growth, improve quality and increase yield.

Brassinolate. Spray 3000-4000 times Brassinolate solution on the strawberry leaves, which can increase chlorophyll content in leaves, enhance photosynthesis , promote sugar content and reduce acid content. In this way, the fruit can be brightly colored, improve the intrinsic and appearance quality of the fruit and enhance the value of the goods. At the same time, it can also enable the fruit to mature early and go public early.

Gibberellin. Strawberries flower bud can be formed in low temperature and short sunshine conditions. However, when the temperature is too high and the normal low temperature is not met, the plants will grow dwarfing, the buds will reduce differentiation, and the flowering results will be few.

In order to promote flower bud differentiation, each strain was sprayed gibberellin solution 5ml that specification is 5-10mg/l after planting. After 7-10 days, you can spray once.

4. Improve the fruiting rate and reduce the abnormal fruit.

Butyl Hydrazine. In the late autumn and early winter, the plant can be sprayed with 1, 000-2000 mg/l butyl hydrazide solution, which can effectively protect against cold and cold. This has no adverse effect on the growth of the plant. In addition, if the strawberry in the harvesting period is overgrown, it can also be used to spray a 1000-2000mg/l butyl hydrazide solution to regulate the balance of vegetative growth and results. In this way, it can increase yield and enhance the cold resistance of the plant.

Naphthalene Acetic Acid. The plant was respectively sprayed with 50-150mg/l naphthalene in the early flowering stage of strawberry, the flowering stage and the fruit period. Spray each plant 5ml solution with a syringe without a needle. In the 10 days before flowering, the leaf surface was sprayed with 0.3% boric acid, and the abnormal fruit rate decreased from 25.26% to 9.92% to 15.25%.
