When will the oak be planted and bear fruit?

Planting:

The best sowing time for oak seeds is from February to May and from August to October each year, and the oak seeds sown at these two times have the highest germination rate and grow the best. The sowing depth should be kept at about 1cm to 2cm.

Results:

Oak trees are mainly propagated by seeds and can germinate in 2-3 weeks. Oak trees mature very late and will not blossom and bear fruit until 10-12 years later. The flowering period is generally from April to May, and the fruit is mature around October.

Can acorns be eaten?

1. The fruit of an oak tree, acorns, is edible. Acorn is the fruit of oak tree, shaped like a silkworm cocoon, so it is also called chestnut cocoon. Acorn appearance hard shell, brown red, inner kernel such as peanut kernel, rich in starch, the content is about 60%. It is not only edible, but also used as raw material for sizing in textile industry.

2. It should be noted that some acorns (especially black acorns of red oak) contain a lot of tannins, which will feel bitter if eaten without treatment. The green acorns of white oak have lower tannin content and taste sweet, so they can be eaten raw or cooked. The basic practice of acorns is to cook acorns for a long time and change water to remove tannins, so that they can be eaten directly after cooking. Acorns can also bake or mix noodles, acorn flour often has a special fragrance, because acorns contain more oil, acorn flour must pay attention to storage so as not to harass. Acorn powder can also be used as a coffee companion.

What kind of environment is suitable for oak trees

The quality of the soil directly determines the growth level of oak seedlings, and also directly determines whether the seedlings grow healthily or not. if the soil is good and the growth environment is good, then the management will be much easier, and the quality of the seedlings and the growth rate will also be greatly improved. Oak trees are not strict with soil, and it doesn't matter if they can grow in sand, loess, clay and sandy soil. Sowing seedlings should choose high-quality fields with soft and ventilated soil, rich in organic matter, flat terrain and smooth drainage. When there is more water in summer, Rain Water should be able to discharge it in time, otherwise it is easy to die in a large area. The terrain is mainly conducive to drainage, the soil is generally available, enough exposure time, oak cold resistance is not afraid of less rain and waterlogging ability is stronger.

II. Land preparation

1, cultivated land: oak seedlings are particularly sensitive to soil fertilizer, soil fertilizer is enough, the growth can be exuberant oil green, plant health. But the soil of very few fields is fertilizer-like terrain, so if you want the young seedlings to grow sturdily and healthily, you need to apply enough organic fertilizer before sowing, spread cow manure and pig manure with 4.5 to 6.5T per mu of land, plough the land once after using fertilizer, and rake the land once, so that the soil and nutrients are stirred together fully and evenly, and there are no big soil bumps, so it is easy to sow and sprout.

2. Bedding: in order to facilitate the management of irrigation, weeding and fertilization of oak seedlings in all growing periods, Changjing Garden recommends that you make the land into a fixed 1.4m wide bed, 16m to 22m in length, depending on the landform.

How to plant oak trees

The oak seed size is average, the emergence level is strong, can do some simple germination treatment before sowing, part of the process is actually very simple, soak in cold water for a day, and then take out the stale dry can be planted, sowing depth is appropriate or shallow, cover the soil depth of not more than 5 cm. It is commonly used to sow seeds in rows, and after sowing, you can also lay plastic film or moisturizing materials such as straw to increase the germination rate. After planting, you can cover the soil by hand or mechanically. after covering the soil, irrigate once, and it can germinate in about 6-9 days.

Fourth, how to raise oak trees

There are few things to manage and protect the oak at the seedling stage, it is basically pest-free and grows well. The main work is irrigation, weeding and prevention of diseases and insect pests. During the peak growth period of Astragalus membranaceus, uncontrolled water and fertilizer are needed. During this period, 30 kg of compound fertilizer can be applied per mu, and sufficient water is needed for the fastest growth of oak trees. At this time, combined with the situation of Rain Water, decide the watering times and time.
