Background technology
Oil palm (Elaeis guineensis Jaca) belongs to Palmae (Palmaceae), originates in Nigeria, Guinea of Tropical Africa West Coast, in the global area of planting, only limits to north and south latitude 18 degree with interior torrid areas.Oil palm is important tropical woody oleiferous plants crop, and its fruit oil content is the highest oil-produced vegetable of production efficiency in the world up to more than 50%.Its major product palm oil has important function in industry and daily life, be widely used in industry, culinary art and food manufacturing.In addition, palm oil is again the best raw material of bioenergy-diesel oil.Oil palm is as the quality raw materials of biodiesel and edible oil, per unit area yield height, profitable on ecology not only, palm oil average production cost are only about 150 dollars/ton, but world's palm oil price maintains RMB 4600-5600 unit/ton substantially, real cost of production is lower, the economic benefit height.Because oil palm is with the obvious advantage, the market demand is huge, the potential advantages that have the biodiesel cheap raw material especially, not only Malaysia, Indonesia, Thailand etc. transform agricultural production one after another, greatly develop oil palm and produce, some developed countries (as the U.S. etc.) also take part in oil palm plant husbandry, purchase oil palm plantation one after another, enclose the land exploitation etc., contention and the control oil palm resources of production.
The oil palm seedling of high-quality is the basis of oil palm industry development; yet; for a long time, China's oil palm industry is in scattered and spontaneous state of development, seedling breeding technological lag; phenomenon such as lack of standardization; do not meet the large-scale production requirement, breeding of oil palm seedling is many by means of the knowhow productions, often because seedling is selected unreasonable; cause the loss of great amount of manpower and material resources and financial resources, cause the oil palm industry development of China slow.
Therefore very be necessary to formulate oil palm seedling breeding technical regulation, the standard oil palm breed the base selection, breed that kind is selected, every standards such as harvesting standard of the soil management in seedling stage and water and fertilizer management, high quality seedling, for China's oil palm industry development provides safety guarantee.Pertinent literature is not also found the report that relevant oil palm seed seedling is bred by retrieval.
Summary of the invention
The purpose of this invention is to provide a kind of oil palm seed seedling mating system, the production cycle that its a large amount of sproutings, raising survival rate, shortening oil palm seed seedling that can bring out oil palm kind fruit is effectively bred, quicken the quick growth of oil palm nursery stock, be significant for the development of oil palm industry.
The technical solution adopted in the present invention:
A kind of oil palm seed seedling mating system comprises seed treatment process in early stage, vernalization treatment process, seed cultivation operation, and its concrete steps are as follows:
1, the oil palm fruit after will be preferred is immersed in hydrochloric acid by volume respectively: the hydrochloric acid solution of water=1: 1~1: 2, sulfuric acid by volume: airtight 24~96h in the sulfuric acid solution of water=1: 1.5~1: 2; With flushing with clean water and break away from pulp, obtain the oil palm seed then, again with 20~40% NaOH solution flushing one time, flushing with clean water afterwards.
2, the oil palm seed that step 1 is obtained is put into water bath with thermostatic control and is cultivated the oscillator change temperature-accelerated germination that vibrates and handle, and processing procedure divided for three steps: it is 60~80 ℃ that the first step begins temperature, vibration rotating speed 25~35r/min, and the duration is 0.5~1h; Second step cooled to 40~60 ℃, vibration rotating speed 20~30r/min, duration 22~23h; The 3rd step cooled to 30~45 ℃, vibration rotating speed 10~20r/min, and the duration is 24~96h; Keep humidity 80~90% during this time, placed then 20~35 days, weed out can not seeds germinated after seeds germinated change breeding phase over to.
3, seeds germinated is carried out the nursery cultivation, and cultivate in described nursery is that Cultivating container is cultivated or casting bed is cultivated.
It is to place the vessel that contain compost to adopt existing rich water quality management mode to cultivate seeds germinated that described Cultivating container is cultivated, wherein compost be by coconut palm chaff, earth and water conservation silica gel by weight the coconut palm chaff: earth: water conservation silica gel=mix at 1.8: 3: 0.08.
It is to place the casting bed that contains compost to adopt existing rich water quality management mode to cultivate seeds germinated that described casting bed is cultivated, and wherein compost is effluent sand and water conservation silica gel by weight river sand: water conservation silica gel=mix at 4.9: 0.1.
The present invention utilizes pulp soda acid spin off method, vibration change temperature-accelerated germination isotype can bring out the production cycle of a large amount of sproutings of oil palm kind fruit, raising survival rate, the seed growing of shortening oil palm seedling effectively, quicken the quick growth of oil palm nursery stock, have simple, the characteristics such as the cultivation time is short, germination rate is high, survival rate height of technology, be significant for the development of oil palm industry.
