The latest course on planting techniques and methods of Prunus tomentosa

Apricot, also known as French spinach, New Zealand spinach and so on, is an annual succulent herb of the Apricot family, which is widely distributed in the southeast coastal areas. it is rich in iron, calcium, vitamin An and various vitamins, and can be used as vegetables. it can also be used medicinally for heat-clearing and detoxification, expelling wind and detumescence, with high cultivation value. Let's take a look at the planting techniques of apricot.

Growth habits of Prunus armeniaca

Apricots like warm, heat-resistant, drought-resistant, suitable for all kinds of soil cultivation, but also wild in the beach. It has strong adaptability, low temperature and drought resistance, but the aboveground part is not resistant to frost, and the suitable temperature for growth and development is 20-25 ℃. The requirement of light condition is not strict, and it grows well in both strong light and weak light.

Sowing techniques of Prunus tomentosa

1. Seed preparation: if there are enough apricot seeds, close sowing or close planting can be considered, and then inter-plucking and harvesting can increase the early yield. Apricot can be direct seeded, can also raise seedlings and transplant, such as apricot seed shortage, it is best to raise seedlings and transplant. Direct seeding needs to prepare 4 kilograms of seeds, seedlings need to be planted with burrow plates or nutritious sports seedlings, to reduce root damage, 1.5 kilograms should be prepared. Raising seedlings can save seeds and sow seeds in advance.

2. Land preparation and border preparation: due to the long growing period of apricot, sufficient base fertilizer should be applied, with 10,000 jin of organic fertilizer per mu. The characteristics of soil and apricot like humidity 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 method: 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. The seedlings were fixed in two rows of 4-foot border, with a distance of 30 cm, and cultivated in 3 rows of 5-foot border, with a distance of 40 cm and 4000 seedlings per mu.

Field Management of Prunus armeniaca

1. Moisture: the pericarp of apricot is hard, the emergence of seedlings is slow, and attention should be paid to watering during spring drought. When raising seedlings and transplanting, because the root regeneration of apricot is difficult and weak, slow seedling is very slow, so it is necessary to replenish water in time to promote 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 upright, 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.

4. Harvest: 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.

Disease and pest control of apricot

1. Pieris rapae: Pieris rapae was sprayed with 32% BT wettable powder 2000 times, or 10% nicotine emulsion 500 times 1000 times, 5% Yitaibao EC 2000 times 3000 times.

2. Fusarium wilt: Fusarium wilt was irrigated with 800-1000-fold solution of 70% methyl topiramate wettable powder or 800-1000-fold solution of 50 carbendazim wettable powder, once every 5-7 days, continuously for 2-3 times. The virus disease was sprayed with 100-fold solution of 10% 83 enhancer at seedling stage twice every 15 days. At the initial stage of the disease, 20% virus A wettable powder, 1000 times, or 5% Shiduqing wettable powder 300 times 500 times, once every 10 days, were sprayed for 3 times.
