Picture description of how to plant chestnut for germination

1, chestnut breeding and germination do not need special treatment, the key is to pay attention to winter storage. Generally, sand storage is adopted, that is, sand and chestnuts are mixed according to the ratio of 1:2, and then holes are dug in places where there is no water in winter, and they are put in and covered with soil for 40 cm. Straw is best covered with heat preservation, and taken out when sowing in March and April in spring to screen out the seeds.

When sowing, we should sow on the ridge. Use a hoe to clear the furrow with a width of 10 cm and a depth of 10 cm, and sprinkle with base fertilizer, usually diammonium or compound fertilizer. Then, tread flat with your feet, plant the seeds in a furrow 20 cm away, spread the seeds flat, cover them with 5 cm of soil and compact them.

3. Pay attention to keep the soil moist when sowing. It is best to use 50-60 chestnuts per catty as seeds, and seedlings with too small seeds will not be strong. Generally, the emergence rate of 50 seeds in the same year can reach more than 95, and the first-class seedlings can reach more than 60. Chestnut seeds will germinate in about 10 days.

Extended data:

Chestnut is the general name of FAGACEAE trees or shrubs, with about 7-9 species. China is generally divided into two types: wild chestnut and hybrid improved chestnut.

Nuts are enclosed in the involucre of dense panicles, with a diameter of 5~ 1 1 cm, and there are 1~7 nuts in one involucre. The flowering period is May-June, and the fruit maturity is 9-65438+1October.

The annual average temperature of chestnut is 10.5~2 1.8℃, the absolute maximum temperature is not more than 4 1.6℃, and the absolute minimum temperature is not less than-24.5℃. Chestnut has a strong adaptability to humidity. Generally, it can be cultivated when the annual precipitation is above 1000mm and the annual precipitation is 500-2000 mm ..

Chestnut has low requirements on soil, and is suitable for growing on sandy loam with deep soil layer, good drainage and low groundwater level. Soil humus is more conducive to the growth of mycorrhiza, and the PH value is 5~6.
