Embodiment 1

[0042] In 2014, hydroponics was carried out in Guankou Village, Jingyanghe Township, Jianshi County, Hubei Province.

[0043] 1. Seed harvesting: On December 25, the ripe fruit of Jatropha was picked with a stalk in Guankou Village, Jingyanghe Township, Jianshi County, Hubei Province.

[0044] 2. Seed drying: Spread the harvested seeds on a bamboo mat and let them dry naturally in a ventilated place until the color of the fruit turns dark black and the pulp and seeds are easily separated. During the spreading and drying process, turn the seeds once a day to promote the evaporation of seed moisture.

[0045] 3. Remove the pulp: remove the seed pulp, rub it with your hands to separate the pulp from the seeds, and remove the pulp and stalk. Sieve with an ordinary bamboo rice sieve to remove seeds and impurities.

[0046] 4. Seed soaking: Soak the seeds in 55°C water for 30 minutes, add 10% detergent during the soaking process, and keep stirring. After warming and soaking the s...

Embodiment 2

[0054] In 2015, in Hehua Village, Shaxi Township, Lichuan City, Hubei Province, we carried out hydroponics in the paddy fields of Jatropha japonica.

[0055] 1. Seed harvesting: On January 8, 2015, the jacaranda fruit was picked on the fine-fruited mother tree with fruit stalk in Hehua Village, Shaxi Township, Lichuan City, Hubei Province.

[0056] 2. Seed drying: spread the harvested seeds on a bamboo mat and let them dry naturally in a ventilated place until the color of the fruit turns dark black and the pulp and seeds are easily separated. During the spreading and drying process, turn the seeds once a day to promote the evaporation of seed moisture.

[0057] 3. Remove the pulp: remove the seed pulp, rub it with your hands to separate the pulp from the seeds, and remove the pulp and stalk. Sieve with an ordinary bamboo rice sieve to remove seeds and impurities.

[0058] 4. Seed soaking: Soak the seeds in 55°C water for 30 minutes, add 10% detergent during the soaking proc...

Embodiment 3

[0066] In 2016, we carried out hydroponics in plug trays in the Paddy Fields of Jatropha japonica in Aishan Village, Gaoluo Township, Xuan'en County, Hubei Province.

[0067] 1. Seed harvesting: On November 28, 2016, the Jatropha fruit was picked from a high-quality fruiting mother tree with a stalk in Aishan Village, Gaoluo Township, Xuanen County, Hubei Province.

[0068] 2. Seed drying: spread the harvested seeds on a bamboo mat and let them dry naturally in a ventilated place until the color of the fruit turns dark black and the pulp and seeds are easily separated. During the spreading and drying process, turn the seeds once a day to promote the evaporation of seed moisture.

[0069] 3. Remove the pulp: remove the seed pulp, rub it with your hands to separate the pulp from the seeds, and remove the pulp and stalk. Sieve with an ordinary bamboo rice sieve to remove seeds and impurities.

[0070] 4. Seed soaking: Soak the seeds in 55°C water for 30 minutes, add 10% deterge...

Abstract

The invention belongs to the technical field of reproduction of idesia polycarpa, and discloses a plug water planting method for idesia polycarpa rice fields. The plug water planting method includes filling plugs with mixed culture media of turf, vermiculite and perlite, and sowing seeds; soaking the plugs by half height; performing germination at 30-35 DEG C, and keeping the water level at 10cm;when each idesia polycarpa seedling has four leaves and a core, transplanting the plant seedlings to a large field. The plug water planting method has the advantages that seedbeds are selected on thespot, nursery stocks are directly transplanted to the large field, and accordingly, transport cost of the nursery stocks is reduced; root-protection transplanting is performed through the culture media, so that planting survival rate is increased greatly, and soil-borne diseases are avoided; moisture supply for the idesia polycarpa seedlings is guaranteed sufficiently, growth is accelerated, and high-quality strong seedlings with orderly sprouts, free from diseases and pests and short in culture period can be produced; by the plug water planting technology for the idesia polycarpa rice fields,the high-quality strong idesia polycarpa seedlings without germs, high in survival rate, short in culture period and low in cost can be produced; the plug water planting method is worth wide promotion.

Description

technical field [0001] The invention belongs to the field of jatropha propagation technology, and in particular relates to a method for hydroponic cultivation of jacaranda in paddy field plugs. Background technique [0002] At present, my country's jatropha seedlings are all grown in seed soil seedbeds. Soil reproduction and germ growth, especially seedling damping-off, blight and root rot, lead to the failure of Jatropha seedlings. [0003] To sum up, the problem existing in the prior art is that the present jatropha seedlings have damping-off disease, blight and root rot, which lead to the failure of jatropha seedling cultivation. Contents of the invention [0004] Aiming at the problems existing in the prior art, the invention provides a method for hydroponic cultivation in plugs of jacaranda paddy fields. [0005] The present invention is achieved in this way, a method for hydroponic cultivation in a jacaranda paddy field plug, said jacaranda paddy field plug hydropo...
