Methods of growing seedlings from apricot seeds:






In order to shorten the seedling cycle of apricot trees, the fresh seeds of mountain apricot and apricot can be used to smash the husks, preserve the seed coat, or peel off the seed coat at the tip of the embryo, and sown in the open field or in a 30°C incubator with a moist cover. The sand accelerates the germination, and the seeds are sown in the middle and late June to early July. According to the experiment of the Fruit Tree Institute, the seedling rate is 30~100%. The seedling height is 50 cm and the stem thickness is 0.42 cm.


In addition, according to the practical experience of fruit growers, it is generally not feasible to raise seedlings with dry seeds for some sweet kernels and apricots. After the apricots are harvested, take fresh seeds to accelerate germination and sowing, or use wet sand to cultivate them in the shade, heat preservation over summer, autumn, and winter, and then layer them according to the conventional method to cultivate seedlings of sweet kernels without grafting.


(1) Seed storage: Choose a shady and dry place, dig a hole 60 cm deep, 1 meter wide, and the length determined by the amount of seeds. Spread a layer of 15 cm of sand on the bottom of the pit, and then place a portion of seeds and 2-3 After the wet sand is mixed evenly, it is put into the pit for sand storage. The upper part of the pit is covered with 20 cm thick wet sand, and then the soil is higher than the ground in the shape of a steamed bun, with a thickness of 10--20 cm. Mountain apricot seed shells are thick, and the sand storage time is generally more than 3 months. The earlier the sand storage time, the more natural husk seeds in the following year.


Soaking seeds: In spring soaking time, the stored seeds can be soaked in a plastic bag and placed directly in the sun. Sprinkle and agitate them every 2-3 days. After 15 days, the seeds will be cracked before sowing. If the amount of seed is small, the shells can be broken artificially before spring sowing and then soaked in warm water to accelerate germination before sowing. The seeds treated by the above methods are taken out for sowing from late March to early April, and the nursery is irrigated once before sowing. After the water has penetrated, the plantar fertilizer is applied, and the ground is prepared by ditching and sowing.


(2) Another type, the fresh apricot kernels harvested that year, immediately break the hulls to take out the seeds, peel off the seed coats and sow the seedlings that year.


Choosing a good apricot tree variety is an important condition for planting apricot trees. According to local conditions, it is natural to choose some good apricot tree varieties with strong drought tolerance.


The selection of seeds is a key part, which is related to whether the apricot trees are highly productive in the local area. After selecting the seeds, in order to ensure the emergence rate during spring sowing, in winter, the seeds should be stratified, that is, the seeds should be stored in sand.


After mixing the seeds, first spread a layer of wet sand on the bottom of the pit, and then put the mixed seed cores into the pit until the pit mouth is about 30 cm. The top should be filled with wet sand, and finally the soil Pile a mound above the ground, the height of the mound is appropriate to prevent accumulation of water.


Sowing here is divided into spring sowing and autumn sowing. It needs to be adjusted according to the local climatic conditions. Basically, the method of sowing can be mainly by ditching and sowing. Good, the width of the furrow should be appropriate, keeping a certain row spacing and plant spacing.


For planting apricot trees, soil management is very important. In autumn, turn the soil about 20 centimeters deep to maintain sufficient aeration of the soil and increase the soil's fertility retention capacity, which is conducive to better root growth. .


Reasonable fertilization can increase the fruit-bearing rate of apricot trees. Basically, organic fertilizer should be used as the main ingredient, and some diammonium can be added. The basic base fertilizer can be applied in autumn. The top dressing requires two top dressing operations before flowering in spring and after the apricot trees have set fruit. The basic top dressing should be based on urea fertilizer, combined with some double presses, and put it in a shallow groove, which has a good promotion effect on fruit setting and fruit development.


Perform a water permeation before germination to meet the needs of apricot blossom and growth. After flowering and during the fruit expansion period, water permeation is needed to improve the fruit setting rate and fruit quality. The second is plastic surgery. During plastic surgery, you need to follow the growth habit of the apricot tree, and use the natural round head shape to make a slight artificial adjustment to ensure that the growth of the apricot tree is more in line with its growth habit. is followed by overwintering protection, which is also very important for almond trees. Commonly used methods are whitewashing, rooting soil, and grass wrapping to prevent excessive damage to the bark caused by low temperature.


The apricot tree is a positive tree species with strong adaptability, deep rooting, light-loving, drought-tolerant, cold-resistant, wind-resistant, and a life span of more than one hundred years. It is the main cultivated fruit tree in low mountain and hilly areas.


How to plant and germinate apricot kernels?


Choose the soil with a deep soil layer and loose soil. The sowing land is first turned over with a mountain plow, the rake is flat, and the plow is used to ditch for sowing. The row spacing is about 30 cm, and the seeding depth is 10-15 cm;


The seeds should be those that are fully mature and full of seeds collected that year. If the seeds are old, bleach them with clean water before sowing to remove stubborn seeds and moldy and deteriorating seeds, and increase the amount of seeding appropriately.


The planting time is good in autumn and winter before the land freezes. The seedling emerges neatly in the following year, and the seeds do not need sand storage treatment, which is simple and easy. When sowing, the seeds need wet sand to accumulate to accelerate germination.


Extended information:


When the new shoots grow to about 15 cm, start to apply quick-acting fertilizer, and alternate underground topdressing and foliar spraying. Apply organic fertilizer and compound fertilizer from the end of September to the beginning of October.


After the shed, apply urea before germination, topdressing potassium sulfate compound fertilizer after flower fading to fruit swelling period, spray urea and potassium dihydrogen phosphate for 10-15 days, and spray 500 times at the same time to increase the production of bacteria. After the seedlings are planted, water them thoroughly, and then determine the watering amount and watering time according to the specific situation.


At the end of May and the beginning of June, the shoots will be dried and fixed. Choose 7-12 shoots with a better angle, and erase the rest. When the new shoot grows to 40 cm, select 2-4 key cultivation, and carry out "V"-shaped or happy-shaped pruning.
