Description

A kind of rapid cultivation method of coconut seedlings

technical field

The invention belongs to the technical field of plant seedling propagation, and relates to a cultivation method of coconut seedlings, in particular to a rapid cultivation method of coconut seedlings.

Background technique

Cocos (Cocos nucifera L.) is an evergreen tree belonging to the palm family Cocos, mainly distributed between 20° north and south latitudes. Coconut not only has high edible and medicinal value, but also is an excellent garden tree, which can be used as street tree, landscape tree and garden tree reflecting tropical and subtropical scenery.

The economic life of coconuts is as long as several decades, and the breeding of good varieties and seedlings is one of the important foundations for establishing fast-growing, premature and high-yield coconut orchards. At present, coconuts are basically propagated by planting fruit. The common method in production is ground seedling raising. This seedling raising method has disadvantages such as long seedling time, few good seedlings, and large damage to the root system during transplanting. rate and later growth have a greater impact. In the actual production process, a new method is urgently needed to solve the above problems. Therefore, how to make full use of the coconut fruit to carry out rapid breeding to produce high-quality seedlings, and to provide the guarantee of good seedlings for the healthy development of the coconut industry has become a current production issue. key issues to be resolved.

Contents of the invention

The purpose of the present invention is to provide a kind of rapid cultivating method of coconut seedling in view of the deficiencies in the prior art, adopt hardened nursery pond and loose cultivation medium to carry out seedling breeding, can effectively solve coconut seedling time long, seedling The problem of low quality is conducive to the production of large-scale high-quality seedlings, and provides an effective way for the promotion and application of its industry.

The technical scheme adopted in the present invention:

A kind of quick cultivation method of coconut seedling, its step is as follows:

1. Preparation of the nursery: Dig a nursery pond 0.3-0.4 meters deep on the ground of the nursery. The bottom and surroundings of the nursery pond are surface hardened, and drainage holes are reserved. The surface hardening treatment of the nursery pond can prevent the roots of the seedlings from growing into the soil outside the nursery pond, and avoid damage to the root system of the seedlings when transplanting in the field.

2. Preparation of the medium: Sterilize fully decomposed coconut peat and mix it with river sand at a volume ratio of 5 to 15:1, fill it into the nursery pond, and make it flush with the ground.

3. Pregermination: Harvest the mature healthy coconut fruit after harvesting "Bailu", and use the open field method for germination.

4. Seedling breeding: The germinated seeds and fruits are moved into the nursery pool in batches for seedling cultivation. The nursery management adopts the conventional mode. After seven months, the seedlings that have reached the planting standard are removed for planting after hardening.

The surface hardening treatment of the seedling pond is treated with cement material.

The bactericidal and insecticidal treatment of the coconut bran is carried out with 400-600 times of carbendazim solution for sterilization, and 800-2000 times of phoxim solution for insecticide.

The invention has simple process and easy operation, adopts the hardened seedling pond and loose cultivation medium for seedling breeding, can greatly speed up the seedling raising process, ensures the integrity of the seedling root system when transplanting in the field, and can effectively solve the long time for coconut seedling raising , The problem of low seedling quality is conducive to the production of large-scale fine seedlings, and provides an effective technical approach for the development of coconut industry.
