Technical Measures to Improve the Survival Rate of Fruit Cutting in Spring

1 The quality of seedlings is one of the important factors affecting the survival rate of fruit trees. The seedlings with high technical specifications should be selected as far as possible, such as no pests and diseases, robust growth, well-developed roots, and short internodes.

2Mentions should be carefully selected before planting, except for weak seedlings, leggy seedlings, and wounded seedlings.

2. Fruit seedling finishing

1 After the fruit trees were dug out of the nursery, the roots had been damaged. To reduce the area of ​​injuries, they should be trimmed. The scissors should remove some of the main roots. The large lateral roots should be cut flat from the injured area. Do not cut them obliquely. The wounds are easy to recover.

2 After the excavation of the root system, sufficient water cannot be absorbed from the soil to allow the upper part of the leaves to evaporate, 2⁄3 branches of the leaves are cut off, and the amount of transpiration is reduced, thereby increasing the survival rate.

3. Planted at the right time

1 Spring planting should be carried out before seedling sprouting. Early or late planting is not conducive to seedling survival.

2 The characteristics of different tree species should be different in the planting time, peach, apricot, plum, etc. should be early, jujube trees, etc. should be late.

4. Colonization technology

1 Applying base fertilizer: Apply 1 kg of seaweed fertilizer, 2% of bacterial fertilizer and 0.2% of bio-organic bacteria in each planting hole, and plant with soil.

2 Nutrient solution immersed root: Before transplanting, soak root for 30 minutes in a nutrient solution prepared with root 15 ml, extremely good 25 ml, and water 10 L, which can promote root wound healing, speed up the restoration of root growth, and increase the survival rate.

(3) Unmarring membranes at the interface of grafting: If the grafted membranes are not lifted, the upper and lower part of the grafting interface will grow bold, while the growth of the grafted interface will not be synchronized. When the wind blows, it is easy to break off from the grafted interface.

4 Flatten the root system: Put the seedlings into the planting hole and flatten the root system so that the root system will stretch to ensure that the root system grows normally.

5 Drenching water in the ampoules: Put the seedlings into the planting hole, cover with a thin layer of fine soil, fill the ampoules with water to make the root soil connect tightly, and then cover with a layer of soil.

6 pay attention to marry the interface: persimmon fruit trees to be exposed when the grafting interface, plum, peach, chestnut and other fruit trees do not expose the marry interface in order to normal growth and development.

7 Covering the tree tray: After planting, cover the top soil of the tree shrew with straw, thatch, crop straw or pig cow dung to keep the soil moisture and help the fruit trees recover.

5. Covering film

1 The shrub cover can effectively increase the ground temperature, protect the drought, and promote the early bud growth.

2 After the fruit trees have been planted, the surrounding pods will be made into shallow pans with the center of the planting seedlings as the center, and the mulch covering 80 to 100 square meters will be covered.

6. Fertilizer management

1 The shrub cover can effectively increase the ground temperature, protect the drought, and promote the early bud growth.

2 Each time the fruit trees were planted, the water and fertilizer were poured on the 10th and 20th days, which was the key to restore the root growth. Ten days after colonization, root callus began to recover. At this time, each plant was rooted at a ratio of 15 ml of roots, 15 ml of good quality, 250 g of high-nitrogen fertilization and 50 liters of water, and 1 liter per pond. Vitality, shorten the slow seedling period.

3 20 days after planting, fertilize with high-nitrogen fertilization 250g, 3 甲 霜 霜ff 霉 23g, water

3 20 days after planting, according to the ratio of high-nitrogen fertilization 250g, 3? A cream?f 23mg, water 50L, pouring 1L per pond, can promote new shoots robust.

From April to August, a high-nitrogen fertilization of 0.3? was applied once a month, and the survival rate of seedlings was 95?.

7. Dry

1 According to the cultivation requirements, choose 3 to 5 full shoots at the height of the cut to cut, cut the mouth and require smooth, no cleft palate and sealant or wrap film to prevent dehydration and drain.

2 In areas with frequent spring winds, supportive pillars should be established to prevent the tree from destabilizing.

8. Post-plant management

1 New planting fruit seedlings, to create a good environmental conditions for the growth of fruit seedlings as much as possible.

2 In accordance with the management principle of “previous promotion and post-control”, the newly planted seedlings will be timely irrigated according to the growth status of the fruit trees and the soil moisture content, and top-dressing will be timely.

3 Pay attention to the prevention and control of pests and diseases during the seedling period.

Organic Wheatgrass Powder

Organic wheatgrass powder is a powder made from fresh wheatgrass. Like most plants, wheatgrass contains chlorophyll, amino acids, minerals, vitamins, and enzymes. Wheatgrass powder is one of the most nutritious green superfoods in nature. Wheatgrass is young and fresh wheat, it contains a series of important phytonutrients. Wheatgrass powder is the [king of alkaline food". It contains a lot of vitamin C, β-carotene, and antioxidant enzymes. Long-term consumption can improve the acidic constitution, purify the blood, promote metabolism, enhance the body`s anti-infection, antibacterial, and analgesic effects. Other effects, long-term consumption can alkalinize blood and urine, increase uric acid excretion, thus effectively reduce gout attacks. Minerals such as potassium, magnesium, and calcium can relieve stress, get rid of sub-health, and delay or improve menopause.
