Problems solved by technology

However, in the process of dry heat treatment, there are also problems such as too fast loss of seed water, high mold rate and high labor intensity. It is necessary to continuously humidify, add medicine and clean moldy seeds during dry heat treatment, which is labor intensive.

Embodiment 1

[0086] 1. The collected oil palm ears are retting, de-fleshed, washed and removed to obtain 100 seeds, and the seeds are placed in a drying room at 40°C to dry to reduce the water content to 17%.

[0087] 2. Seed dry heat treatment: pack the pretreated seeds with tin foil, and then place them in an insulated room at 38-40°C for dry heat treatment for 45 days [during this period, it is not necessary to carry out any anti-mold and anti-dehydration treatment on the seeds (humidification and chemical addition) , until the end of dry heat treatment].

[0088] 3. Seed germination pretreatment: soak the dry heat-treated seeds with water to increase the water content to 20%, and then soak them in a bactericidal liquid containing 0.2% thiram and 0.1% anionic surfactant for 3 to 5 minutes. Finally, the surface of the seeds is dried in the shade indoors.

[0089] 4, seed germination treatment: put the seeds after the germination pretreatment into a plastic bag, seal it, and then germina...

Embodiment 2

[0091] 1. The collected oil palm ears are retting, de-fleshed, washed and removed to obtain 100 seeds, and the seeds are placed in a constant temperature drying oven at 38°C to dry to reduce the water content to 18%.

[0092] 2. Dry heat treatment of seeds: Pack the pretreated seeds with aluminum foil paper, and then place them in an insulated room at 40°C for dry heat treatment for 60 days [during this period, it is not necessary to perform any anti-mold and anti-dehydration treatment on the seeds (humidification and chemical addition), until the end of dry heat treatment].

[0093] 3. Seed germination pretreatment: soak the dry heat treated seeds with water to increase the water content to 22%, and then soak them in a bactericidal liquid containing 0.2% thiram and 0.1% anionic surfactant for 3 to 5 minutes. Finally, the surface of the seeds is dried in the shade indoors.

Abstract

The invention belongs to the technical field of bud acceleration of seeds of oil palm, in particular to a dry heat bud accelerating method for seeds of oil palm. The method comprises the following steps of: removing impurities from ears of the oil palm, and directly drying the seeds to make the water content reduced to be 17-18 percent; packaging the preprocessed seeds with silver paper or aluminum-foil paper, and performing dry heat treatment in an insulating room at the temperature of between 38 and 40DEG C; soaking the seeds subjected to the dry heat treatment by using clean water to make the water content improved to be 20-40 percent, soaking in a bactericidal liquid medicine, and drying the surfaces of the seeds in a shade; and packaging the seeds subjected to bud accelerating preprocessing into plastic bags, sealing, accelerating buds at normal temperature indoors, and moistening by using the prepared moistening liquid medicine according to the moist conditions of the surfaces of the seeds. The method is simple, and convenient to implement; the silver paper or the aluminum-foil paper serves as a packaging material to replace sealed plastic bags, and the water loss and the mouldy rate of the seeds can be effectively reduced on the premise of not reducing the germination rate of the seeds; and the method has the characteristics of low cost, high efficiency, low labor intensity and the like.

Description

technical field [0001] The invention belongs to the technical field of germination acceleration of oil palm seeds, and in particular relates to a dry heat germination acceleration method of oil palm seeds. Background technique [0002] Oil palm seeds are recalcitrant seeds with a relatively long dormant period. At present, natural acceleration, wet heat acceleration and dry heat acceleration are usually used in production to accelerate germination, and the dry heat acceleration method has the most obvious advantages. The oil palm seeds adopting the natural germination method and the damp heat germination method have a long germination time and a low germination rate, while the dry heat germination method can shorten the dormant period of the seeds, and has the advantages of easy control of the germination conditions, short germination time and high germination rate. At present, the main steps of the dry heat germination method of oil palm seeds are divided into the following...
