Cultivation techniques of Prunus armeniaca

(1) seed preparation: if apricot seeds are sufficient, close sowing or close planting can be considered, and then harvested, which can increase the early yield. Apricots can be directly seeded, or seedlings can be raised and transplanting. If there are not enough apricot seeds, it is best to raise seedlings and transplant. 4 kilograms of seeds are required for direct seeding. Seedlings need to be planted with point plates or nutritious sports seedlings to reduce root injury, and 1.5 kg of seeds should be prepared. Raising seedlings can save seeds and sow seeds in advance. Although the planting of apricot is slow, but the survival rate is very high.

(2) soil preparation, fertilization and bedding: due to the long growing period of apricots, sufficient basic fertilizer, 10,000 jin of organic fertilizer per mu, should be applied, and the characteristics of soil and apricots' preference for dampness and fear of waterlogging should be taken into account. Watering should be convenient and drainage should be good. If there are sprinkler irrigation facilities, flat and high beds can be considered, so that irrigation and drainage can be better solved.

(3) sowing and planting period: direct seeding in the open field can sow seeds at any time from April to May, but early sowing can be more beneficial, and seedlings can be planted in mid-March and mid-late April.

(4) cultivation density: 4 feet of two rows of fixed seedlings, plant spacing of 30 cm, 5 feet of 3 rows of cultivation, plant spacing of 40 cm, fixed seedlings of 3000 to 4000 plants per mu.

(5) Field management:

1) moisture: the pericarp of apricot is hard, the emergence of seedlings is slow, and attention should be paid to watering during drought in spring. When raising seedlings and transplanting, because the root regeneration of apricot is difficult and weak, the slow seedling is very slow (it seems to be dead), so it is necessary to replenish water in time to promote the slow seedling. Sowing and planting late, strong light, drought should be timely watering, in order to prevent virus disease. Accelerate the growth of plants to keep the soil moist, luxuriant plant growth, dense branches and leaves, be careful not to be too wet, dry and wet, too moist and perishable, pay attention to waterlogging prevention in summer.

2) Fertilizer: under the condition of sufficient base fertilizer, chemical fertilizer is mainly applied in field management. Less application at seedling stage, chemical fertilizer can be applied according to the situation when exuberant growth.

3) pruning: apricot is an extensive cultivated crop, but after artificial cultivation, it grows more exuberantly because of good fertilizer and water conditions, but because it grows exuberantly, it is dense and erect, and soon occupies the field. If the harvest is not timely, it will make the growth too dense, encroach on the ridge of the harvest border, and make the internal ventilation poor. Step on the stem vine to cause the wound, poor ventilation and cause rot, so consider to crawl to the ridge stem vine cut off, or sparse between the border stem vine, in order to facilitate ventilation and avoid trampling.

(6) harvesting: the plant slows down and grows vigorously. When the plant is 20 cm high, the tender tip can be harvested, and the lateral branches will grow out in 10-15 days. When cultivated in the open field, the old leaves of apricot are very rough and have no feeling of slippery and tender, so special attention should be paid to harvesting. The quality of protected cultivation is relatively tender because of weak light, and the tender stem tip can be longer after harvest. Because the leaves of apricot are very thick, the growth is fast, and the harvest time is long, so apricot is a high-yield vegetable. It can be harvested in open field for 5 months, and the yield is 3000kg to 5000kg.
