Problems solved by technology

Although there are many methods for pretreatment of jacaranda seeds, some methods can make the seed germination rate greater than 98%, but because the jacaranda seeds are small, the seeds themselves carry less nutrients, which is not enough to support the germination of the seeds to the leaves of the seedlings for photosynthesis Stage nutrient consumption and environmental stress bring pressure, and are susceptible to disease, so even if the Jatropha seeds germinate, the seedlings will survive very difficult, and the purpose of engineering application and the maturity of large-scale production cannot be achieved.

Embodiment 1

[0036] The pretreatment of embodiment 1 Jatropha seeds

[0037] 10,000 jacaranda seeds (about 8.5 grams), first soaked in water for 28 hours, then soaked in straw ash water for 6 hours, rubbed with hands to the extent of the waxy layer on the surface of the damaged seeds, and filtered the straw ash with gauze, The volume ratio of the straw ash water to the jacaranda seeds is 3:1, and the mass ratio of the straw ash in the straw ash water to the jacaranda seeds is 1:1; then put the filtered seeds into clear water Soak in water for 24 hours, take out the seeds and then sterilize with 1% potassium permanganate for 3 hours, pick up the seeds, rinse the residual potassium permanganate on the surface of the seeds with clean water, and get the sterilized seeds. Soak the treatment solution of 3 times the volume of Jacarina seeds at 10°C for 15 hours and then place it in a cool and ventilated place to dry for later use; the treatment solution contains gibberellin and KH 2 PO 4 , the ...

Embodiment 2

[0038] The pretreatment of embodiment 2 Jatropha seeds

[0039] 20,000 jacaranda seeds (about 17 grams), first soaked in water for 40 hours, then soaked in straw ash water for 8 hours, rubbed with hands to the degree of the waxy layer on the surface of the damaged seeds, and filtered the straw ash with gauze, The volume ratio of the straw ash water to the jacaranda seeds is 4:1, and the mass ratio of the straw ash in the straw ash water to the jacaranda seeds is 1:1; then put the filtered seeds into clear water Soak in water for 30 hours, take out the seeds and disinfect them with 1.5% potassium permanganate for 2 hours, pick up the seeds, rinse the residual potassium permanganate on the surface of the seeds with clean water, and get the disinfected seeds. Soak 4 times the volume of Jacarina seeds in a treatment solution at 15°C for 24 hours and then place it in a cool and ventilated place to dry for later use; the treatment solution contains gibberellin and KH 2 PO 4 , the ...

Embodiment 3

[0044] The pretreatment of embodiment 3 Jatropha seeds

[0045] 20,000 jacaranda seeds (about 17 grams), soaked in clear water for 48 hours, then soaked in straw ash water for 8 hours, rubbed with hands to the extent of the waxy layer on the surface of the damaged seeds, and filtered the straw ash with gauze. The volume ratio of the straw ash water to the jacarnia seeds is 5:1, and the mass ratio of the straw ash in the straw ash water to the jacaranda seeds is 1.5:1; then put the filtered seeds into clear water Soak in water for 42 hours, take out the seeds and then sterilize with 2% potassium permanganate for 1.5 hours, pick up the seeds, rinse the residual potassium permanganate on the surface of the seeds with clean water, and get the sterilized seeds. Soak a treatment solution of 5 times the volume of Jacarina seeds at 12°C for 20 hours and then place it in a cool and ventilated place to dry for later use; the treatment solution contains gibberellin and KH 2 PO 4 , the ...

Abstract

The invention belongs to the field of forestry sowing and relates to a method for pretreating seeds for Idesia polycarpa Maxim. seedling growing and a method for Idesia polycarpa Maxim. seedling cultivation in the field. Through immersion in straw ash and then kneading, wax on the surfaces of Idesia polycarpa Maxim. seeds is removed effectively, through disinfection adopting potassium permanganate, Idesia polycarpa Maxim. seed morbidity in a germination stage is obviously reduced, and through treatment adopting a treatment solution containing gibberellin and KH2PO4, an Idesia polycarpa Maxim. seed germination rate is improved effectively. The Idesia polycarpa Maxim. seed treated by the Idesia polycarpa Maxim. breeding method has a high seed germination rate and low seedling morbidity. The invention discloses the method for Idesia polycarpa Maxim. seedling cultivation in the field, and the method can be simply managed by a worker, realizes a stocking percent above 99% and lays a good foundation for large-scale Idesia polycarpa Maxim. seedling cultivation production.

Description

technical field [0001] The invention belongs to the field of forestry sowing, in particular to a method for pretreatment of Jatropha seeds and field seedling cultivation. Background technique [0002] Idesia polycarp a Maxim. is a deciduous tree belonging to the genus Idesia polycarp a Maxim. It is an excellent fast-growing timber and ornamental tree species in subtropical regions of my country. Jatropha has the advantages of fast growth, good water and soil function maintenance, large fruit yield, high oil content, good oil quality, and edible. The unsaturated fatty acid content of jatropha oil is more than 80%, the linoleic acid content is more than 70%, the vitamin E content is more than 1‰, and it does not contain toxic and harmful ingredients. E. Excellent raw materials for the preparation of biodiesel and high-grade lubricating oil. If the pulp and seeds can be made into semi-dry oil, it can replace tung oil; it can also be used as a raw material for extracting linole...
