How to plant red date seeds?

Red jujube is a temperate crop with strong adaptability and wide planting range. Known as "iron crops", it has the characteristics of drought and waterlogging tolerance, and is the first choice for the development of water-saving forest and fruit industry. So, how to plant the seeds of red jujube?

How to plant the seeds of red jujube?

Remove the gram of the jujube seed, leave the seeds inside, soak it in warm water for 24 hours, cover it with a wet cloth, rinse with warm water four times a day, and sow most of the seeds after germination. The planting land should be ploughed, applied base fertilizer and dug ditches, ditch distance 65cm, ditch depth 10cm. After filling the ditch with water, the seeds were sown into the soil, the 20cm spacing was maintained, and the ditch was filled after planting. Do a good job in field management in the later stage, and can be transplanted in the spring of the third year.

II. Planting and management of red jujube trees

1. Fertilizer and water management

According to the rainfall, the seedlings can be irrigated once in mid-May, early June and late June to ensure that the seedlings are not dry. After the slow seedling stage in late July, 150 grams of urea is applied to each plant. In addition, after the seedlings germinated and spread their leaves, 0.4% urea and 0.3% potassium dihydrogen phosphate were sprayed on the leaves every 10 to 15 days.

2. Prevention and control of diseases and pests

That is, spraying 2000 times of monocrotophos or 50% Apollo plus 50% methamidophos mixture in late May and early and mid-June can effectively control pests such as red spiders, blind bugs, jujube leaf ticks and so on.

3. Check the replanting

After the seedlings germinated and spread their leaves, the survival of the seedlings was investigated. according to the situation of dead plants and missing plants, the seedlings were replanted with soil in autumn or before germination the next year. In addition, in the year when jujube seedlings were planted, there sometimes appeared the phenomenon of false death without germination. the branches of the false dead plants were soft and the skin was green and bright, so the fake dead seedlings should be watered and ploughed to promote their germination and growth as soon as possible.

4. Protect flowers and fruits

In order to make the jujube bear fruit early and bear more fruit, one is to pick the heart and hit the top during the flowering period of the jujube tree to reduce the consumption of nutrients. The second is to spray 10-15 mg / kg gibberellin or jujube Huabao solution at flowering stage. Carefully spray 50 mg / kg naphthylacetic acid or 10 mg / kg anti-falling hormone solution 2 times 3 times 4-5 weeks before fruit ripening (white ripening period), and spray once every 10-15 days.

The vitamin content of red jujube is very high, and it has the reputation of "natural vitamin pill". It has the effect of nourishing yin and tonifying yang, and can be eaten by ordinary people. people with internal heat and dampness, children with accumulation and parasitic diseases, dental pain, phlegm and dampness, abdominal fullness, thick and greasy tongue coating should be avoided. In addition, people with diabetes should not eat more; and fresh dates should not eat more, otherwise it is easy to produce phlegm, help heat, and damage teeth.
