Method for managing and controlling dwarfed coconut flowers and fruits

Abstract

The invention provides a method for managing and controlling dwarfed coconut flowers and fruits, and relates to the technical field of plant flower and fruit management and control. The method comprises the following steps of: 1) arranging pollination trees in a dwarf coconut garden according to the quantity ratio of production trees to pollination trees (5-10) : 1; 2) applying a flowering agent to the pollination trees within 1-3 days after a spathe of the pollination trees is opened; the flowering agent is ethephon of 50-200 ppm or a naphthylacetic acid of 300-500 ppm ; 3) spraying an anti-dropping agent to the production trees after the pollination is finished; the anti-stripping agent is a mixed solution comprising 50-200 ppm of 2.4-D and 50-200 ppm of an indolebutyric acid. Accordingto the method for managing and controlling dwarfed coconut flowers and fruits, the pollination trees are configured, the male flower quantity is increased, and the female flower shedding is slowed down, so that the fruit setting quantity of the coconut is ensured, the flower and fruit productivity of the coconut is optimized, and the coconut flower and fruit configuration is controlled to promotethe high yield of the coconut, and a foundation is laid for the production and application of the dwarf coconut garden.

Description

technical field [0001] The invention belongs to the technical field of plant flower and fruit control, and in particular relates to a method for controlling the flower and fruit of dwarf coconuts. Background technique [0002] Coconut (Cocos nucifera L.) belongs to the palm family and is an important woody oil crop in tropical and subtropical regions. In Hainan alone, more than 500,000 people are engaged in coconut planting, product processing and scientific research related to the coconut industry. The annual output value of the industry reaches more than 7 billion yuan, which is one of the important components of the national economy. [0003] Coconuts are usually monoecious and cross-pollinated, but most of the dwarf coconuts are self-pollinated (generally, the outcrossing rate reaches more than 20%), the reproduction rate is low, and the yield is greatly affected by itself and environmental factors, which has seriously hindered commercial fruit production for a long time...

Problems solved by technology

[0003] Coconuts are usually monoecious and cross-pollinated, but most of the dwarf coconuts are self-pollinated (generally, the outcrossing rate reaches more than 20%), the reproduction rate is low, and the yield is greatly affected by itself and environmental factors, which has seriously hindered commercial fruit production for a long time. mass production of

At present, artificial pollination can be used to solve the above problems, but artificial pollination has problems such as high cost, labor-intensive, skilled technicians, etc., and the benefits of artificial pollination are very small, and a single plant can produce up to 10 to 15 fruit per year.

[0004] Simultaneously coconut also has the serious problem that female flower and young fruit fall off, and coconut production is subjected to very big loss
