Problems solved by technology

This germination method is not only difficult to control the germination rate of chestnuts, but also needs to adjust the position of chestnut seedlings after sowing, and the excavation of chestnuts will cause certain damage to chestnut seedlings, and the quality of subsequent chestnut seedlings cannot be guaranteed. a more controlled way

Embodiment 1

[0036] 1 Screening of germinated seeds: artificially select the chestnut seeds broken from dormancy by cold stratification, select the chestnuts with insect damage, mechanical damage, and mildew on the surface, discard them, and float the remaining chestnut seeds with clear water, discard them and float them on the surface Chestnut seeds on the surface of clear water are not used, and high-quality chestnut seeds that sink to the bottom of the water are selected for germination.

[0037] 2 Seed soaking: put high-quality chestnut seeds in a container, add an appropriate amount of distilled water to submerge the chestnut seeds, soak at 25°C for 12 hours, pour the distilled water after soaking, and leave the chestnut seeds that have absorbed enough water to germinate.

[0038] 3 Germination preparation: bury the chestnut seeds that have absorbed enough water into the soil, put the soil in a foam box, bury the chestnuts to a depth of 4 cm, and bury a chestnut every 4 cm.

Embodiment 2

[0042] 1 germination seed screening: same as embodiment 1.

[0043] 2 seeds soaking: same as embodiment 1.

[0044] 3 Germination preparation: put the chestnut seeds that have absorbed enough water into a water-storing and breathable cloth bag. The cloth bag is sterilized with 1% sodium hypochlorite solution for 12 hours before use, and the sodium hypochlorite is washed with clean water after disinfection. Rinse the chestnuts in a cloth bag with clean water, and drain until there is no water dripping from the cloth bag.

[0045] 4 Seed germination: Put the cloth bag containing the chestnuts to be germinated in a constant temperature room at 25°C, with light and darkness, and the chestnuts germinate for 6 days. During the germination period, rinse with water for 30 seconds twice a day. After the germination, count the germination rate, bud length and spoilage rate .

Embodiment 3

[0048] 1 germination seed screening: same as embodiment 1.

[0049] 2 seeds soaking: same as embodiment 1.

[0050] 3 germination preparation: same as embodiment 2.

[0051] 4 Seed germination: the wet cloth bag is placed in an incubator, and the germination conditions are: temperature 25° C., humidity 85-95%, light and darkness. Chestnuts were germinated for 6 days. During the germination period, they were washed with clean water for 30 seconds every day. After the germination was over, the germination rate, bud length and spoilage rate were counted.

[0052] 5 Experimental results: After germination by this method, the germination rate of chestnuts is 88.33±3.12%, the bud length is 4.50±0.95cm, and the decay rate is 1.67±1.18%. Most of the chestnuts are in the lateral root stage, and a large number of lateral roots grow from the main root.

Abstract

The invention belongs to the field of plant breeding, and particularly relates to a Chinese chestnut germination method. The invention discloses a Chinese chestnut germination method. The method comprises the following steps: (1) selecting Chinese chestnut seeds for germination; (2) soaking the Chinese chestnut seeds selected in the step (1) in clear water for a certain time; (3) putting the Chinese chestnut seeds treated in the step (2) into a cloth bag; and (4) putting the Chinese chestnut seeds treated in the step (3) into an incubator, and germinating for a certain time to obtain Chinese chestnut seedlings. According to the method, a soil separation germination mode is adopted, the problems that the Chinese chestnut seeds are possibly damaged by pests and rats when germinating in soil and Chinese chestnut seedlings are easily damaged by repeated digging are solved, the germination rate and germination quality of Chinese chestnuts are effectively improved, and the putrefaction rate is reduced.

Description

technical field [0001] The application belongs to the field of plant breeding, and in particular relates to a method for sprouting chestnuts. Background technique [0002] Chestnut (Castanea mollisima BL.) belongs to the Chestnut genus of Fagaceae (Fagaceae) in the order Fagales. It is a kind of economic forest tree species widely planted in my country. economic benefits. Chestnut seeds are typical recalcitrant seeds, which cannot tolerate dehydration during their survival and development. Chestnut seeds still have high water content and physiological metabolic activity when they mature and fall off. The dormancy of chestnut usually takes 2-3 months. When cold stratification breaks the dormancy of chestnut, chestnut with higher water content will germinate under suitable germination conditions. [0003] Chestnuts are generally sown in spring, but they are also sown in autumn. Chestnuts sown in autumn have a high rate of mold and rot due to drastic changes in soil temperatu...
