Method for raising seedling of oil palm seed

Abstract

The invention belongs to the technical field of plant sprout breeding, in particular to a method for raising a seedling of an oil palm seed, which comprises the following steps of: (1) seed harvesting and accelerating germination; (2) seedbed preparing; (3) sowing and seedling-growing managing; and (4) transplanting. The invention has a simple process, is convenient for operation, increases the oil palm seed germinating speed, the germinating rate and the uniformity through combining accelerating germination with seedling-growing manners, improves the sprout quality, cultivates robust sprouts, shortens the oil palm period of immaturity, and provides a high-efficiency method for mass sprouts required by the oil palm planting industry.

Description

technical field [0001] The invention belongs to the technical field of plant seedling propagation, and in particular relates to a method for raising seedlings of oil palm seeds. Background technique [0002] Oil palm (Elaeis guineensis Jacq.) belongs to the genus of oil palm of the palm family. It is native to Africa and is mainly distributed in Malaysia, Indonesia, west and central Africa in Asia, northern South America and Central America. The plant is tall, with fibrous roots, erect stems, unbranched, cylindrical. Leaf pinnatisect, single leaf, spadix (panicle), monoecious, fruit is drupe. The pulp and kernel of oil palm are rich in oil. Among various oil crops, it is known as the "world oil king". my country has introduced oil palms for more than 80 years, and they are mainly distributed in Hainan, Yunnan, Guangdong and Guangxi. [0003] Oil palm likes high temperature, humidity and strong light environment, requires fertile soil, likes humidity but is not resistant t...

Problems solved by technology

The conventional breeding method is to use seeds to raise seedlings. Generally, it can bloom and bear fruit after 3 years of planting. However, the seeds used for production require the mother tree to be over 8 years old and bloom and bear fruit all the year round. It takes 6 months from pollination to fruit maturity, and the peel has fibers. Quality, high oil content, large seed particles, thousand-grain weight greater than 2000 grams, no obvious dormancy period (but improper handling will cause seed dormancy)

Generally choose 6-7 months for seedling cultivation, the germination is irregular, and the high temperature period in summer can last for about 60 days before and after germination, and the germination rate is about 60%. It takes about 2 years from seed collection to seedling planting in the nursery. This method The limitations and disadvantages of the method are as follows: the germination is not uniform, and the maintenance time of the seedbed is long; if the temperature and water are not controlled carefully during the germination period, the embryo activity of the seeds will be affected; the seedling stage is limited by the natural temperature and light conditions.
