Zeatin dosage and function introduce
Zeatin always be used on vegetables, melons, fruit-tree, beans, increase output.
TO used on vegetables: to use zeatin spray after plant 10-20 days, dosage is 0.2-0.3ppm; (0.01% zeatin liquid dilute 300-500 times by water)
To be used on tomato:
When you transplant tomato, You can scok young-plant root by 0.25ppm zeatin (0.01% zeatin liquid dilute 400 times by water);
Spray the second time after transplant 2 weeks, dosage is 0.25ppm;
To be used on apple, pear, grape:
On the bud period, after flower period, young-fruit period and fruit-growth period, you can use zeatin 0.2-0.3ppm to spray, it can help fruit have better color and promote harvest earlier. (equal 0.01% zeatin liquid dilute 300-500 times by water)
To be used on cotton:
On bud period, early-flower period, and pod period, we can use zeatin 0.15-0.25ppm to spray, it can increase pod setting ratio, and increase output. (equal 0.01% zeatin liquid dilute 400-600 times by water);
To be used on corn:
When the corn has 6-8 leaves and 9-10 leaves, we can use zeztin 0.1-0.15ppm to spray twice, (equal 0.01% zeatin liquid dilute 600-1000 times by water), it can help corn have more output, and increase corn weight,
TO be used on rice:
We need spray twice zeatin. First time is before transplant, dosage is 0.2 ppm (equal 0.01% zeatin liquid dilute 500 times by water);
and second time is booting stage. Dosage is 0.17-0.2ppm. (equal 0.01% zeatin liquid dilute 500-600 times by water)
1.Promotes callus initiation when coused with auxin
2.Promotes fruit set
3.Retards yellowing for vegetable, also applied to stimulate seed germination and seeding growth.
4.Before 7 days to spraying 8ppm for three times when the tomato is blossom,flowering period and after flowering. Zeatin can increase yield, increase the rate of 6.59%~18.75% Centhance the vitamin centhance.
5.Spraying 8ppm for 3 times when the blueberries is rosette stage, zeatin can yield increase of 7.13%-16.19%, improve the quality of the blueberries.
