I often hear many farmers say that gibberellin is very good against strawberry pests and diseases. What is the reason? What are the advantages of gibberellin against strawberry pests and diseases? Let's take a look at Xiaobian.
(1) Seedlings. Spraying gibberellin can promote the early growth of strawberry mother plants and the growth of stolons, increasing the seedling yield by 30%-40%, and the proportion of first-grade seedlings is obviously increased. During the spraying period, it is advisable to spread the leaves to the beginning of the bud, and the early spray is better than the late spray. The optimum spray concentration is 50-70 ppm.
(2) Protected cultivation. Spraying gibberellin on strawberry has the effects of breaking dormancy, promoting plant growth and development, early phenological period and early maturity, and increasing yield. Especially in promoting cultivation, it has obvious effect on breaking dormancy and overcoming plant dwarfing. The optimal application period is generally about 7 days after the insulation of the shed (ie, germination to bud stage), the optimal concentration is 5-10 ppm, and the dosage per plant is 3-5 ml. If the concentration is too high, it will appear lengthy, resulting in reduced yield.
(3) Cultivation in the open field. The application of gibberellin on the exposed strawberry can be 5-6 days in early phenology, and the harvesting period is about 7 days earlier, and the yield is increased by about 10%. The suitable spraying time is from the leaf to the beginning of the bud, and the optimum concentration is 3-5 ppm. (4) Precautions. Different varieties of strawberry are sensitive to gibberellin, and should be applied to a large area after testing. At the same time, its spraying effect is also affected by factors such as temperature, humidity and light, and should be flexibly controlled when applied. But also pay attention to the impact on the quality of the strawberry, to ensure the quality of the fruit.
