Plant growth regulator containing forchlorfenuron and its application

Abstract

The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a plant growth regulator containing forchlorfenuron and an application thereof. The plant growth regulator comprises 10-15ppm of forchlorfenuron, 0.02-0.04% of surfactant and the rest are auxiliary materials in terms of mass percentage. Said application is for preventing lychee fruit stiffness. Spraying forchlorfenuron at a low concentration (10ppm) at the fruit consolidating stage of Litchi jizui, and taking measures in the early stage of fruit development, can prevent the occurrence of fruit stiffness in the later stage of lychee fruit, reduce drug residues, and significantly reduce the rate of fruit stiffness. And to a certain extent, it improves the coke core rate of the fruit of Jizui Lily, improves the appearance quality of Jizui Lily, but does not affect the ripening period of the fruit, and increases the commodity value.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a plant growth regulator containing forchlorfenuron and an application thereof. Background technique [0002] Litchi is an evergreen tree belonging to Sapindaceae. It is a world-renowned subtropical fruit tree and a world-class famous fruit originated in my country. The fruit of Jizui lychee is crookedly heart-shaped or oblate, with a round top and flat or slightly shrugged shoulders; when the fruit matures, the seeds degenerate into the shape of a chicken's mouth, so it is called Jizui lychee. Jizui lychee has crisp flesh, sweet and slightly fragrant flavor, small core and thick flesh, with an average edible rate of 79.3% and relatively large fruit. It is a good variety for fresh food, dried and canned. [0003] During the cultivation process of Jizui litchi, there is a situation of poor fruit development, and the fruit is prone to varying degrees of ...

Problems solved by technology

In the early flowering stage of 'Concubine Smile', it was used to stimulate flower turning, but the fruit was difficult to set and deformed easily; when applied in the late flowering, young fruit stage, and expansion stage, it had a significant effect on promoting the fruit enlargement of 'Concubine Smile' (Luo Jianbin et al., 2015), but in During the fruit expansion stage, forchlorfenuron treatment of A4 seedless litchi has no obvious effect on promoting fruit expansion (Yang Mingfu et al., 2015)

If plant growth regulators are used improperly, the residues in the fruit will be too high, which may cause harm to human health
