Olive container nursery method

Abstract

The invention discloses an olive container nursery method. The olive container nursery method is achieved through following steps: 1) preprocessing seeds: storing olive seeds in a freezing room for 3-4 moths; when planting the seeds, fetching out the seeds from the freezing room, and firstly, soaking the seeds in 75% alcohol solution for 0.5-1.0min, then, using 0.1% mercury bichloride solution to sterilize the seeds for 10-15min, and finally soaking the seeds in aseptic warm water for 40-45 hours; then, mixing the seeds with wet sand evenly so as to obtain a mixture, placing the mixture in a brown paper packing box with holes, and accelerating germination on a seedbed; 2) sowing the seeds: placing the primed seeds 30% in opening rate into a ventilated and permeable seedling nursing container, sequentially covering the primed seeds with 2cm fine sand and 1cm selenium-rich soil after sowing the seeds, and then using a black film to cover the seeds for heat preservation; 3) performing seedling management: sprouting the seeds 25-28 days after seed sowing, spraying 0.8-1.2% Bordeaux liquid once every 7-8 days after sprouting, and performing seedling hardening and transplanting when four pairs of main leaves are grown on each seedling. The olive container nursery method has the advantages of being high in emergence rate, high in breeding efficiency, high in seedling quality and the like. Compared with an existing container nursery technology, the olive container nursery method improves integrated quality of the seedlings by more than 5%.

Description

technical field [0001] The invention belongs to the technical field of plant seedling cultivation, and in particular relates to a method for growing olive seedlings in a container. Background technique [0002] Olive, also known as olean fruit, is an important woody oil tree species in Longnan, Gansu and Guangyuan, Sichuan. Olive oil is called olive oil, which contains 65.8-84.9% monounsaturated fatty acids and 3.5-22% polyunsaturated fatty acids. In addition to supplying a large amount of heat energy to the human body, monounsaturated fatty acids can also adjust the ratio of high and low-density lipoprotein cholesterol in human plasma. Eating olive oil can increase the balanced concentration of high-density lipoprotein HDL in the human body to ensure the body's requirements for cholesterol , but also reduce the concentration of low-density lipoprotein LDL in plasma, and prevent excess cholesterol in the human body. Polyunsaturated fatty acids can be divided into omega-3 f...

Problems solved by technology

This technology can significantly increase the germination rate, but the current environmental damage is serious, there are many germs and germs in the soil, and the seeds will be more or less polluted or even destroyed after sowing, which makes it impossible to guarantee all the seeds to germinate or emerge.

Moreover, this method uses plastic seedling containers. Due to the effects of plastic heat insulation, water insulation, and air insulation, the seeds cannot breathe freely in it, which delays the emergence time. This undoubtedly affects economic benefits for large-scale seedling cultivation.
