Although gibberellin is not a plant growth regulator , but it is not suitable for any crop, then which gibberin application is better on which crops? Let's take a look at it with Xiaobian.
1. Improve the yield of hybrid rice. Hybrid rice has a neck of about 10 cm in production, which leads to incomplete heading and inability to pollinate, thus reducing the seed setting rate and affecting yield. In this regard, the application of gibberellin can effectively solve these problems by using 10-15 grams of gibberellin per acre and spraying 2-3 times. The first time the spray is 10%, the 2-3 grams per acre; the second spray on the next day, the amount of 4-6 grams per acre, the third time on the second day or the next day The dosage per acre is 4-6 grams.
2, promote vegetable growth: Many vegetables such as celery, spinach, leeks, sage, etc. can use gibberellin to promote vegetative growth, increase yield and early harvest.
3, break the potato dormancy: dip the block of potato block with 0.5-4ppm concentration of gibberellin for 10-15 minutes, the concentration of the short dormant period is lower, the concentration of the long dormant period is higher, the seed potato after soaking, fishing Dry in a cool place, do not expose to the sun, then you can sow. Thereby breaking the dormancy, promoting the germination of the buds, so that the emergence of seedlings is early and homogeneous.
4, to promote strawberry flowering: Protecting the cultivation of strawberries, spraying 10ppm gibberellin in the early stage, 5 ml per plant, can avoid dormancy and promote flowering results.
