The latest course of apricot seedling raising techniques and methods

Apricot planting mainly depends on the seedlings cultivated by seed sowing, and then the fine varieties can be grafted on this basis to cultivate seedlings with the excellent characters of both varieties. Next, take a look at how to deal with the seeds, how to sow and raise seedlings, and then the specific operation process of grafting, what should be paid attention to.

I. seed treatment

Apricot is a drupe fruit, the seed is tightly closed, the seed shell is very hard, it is not easy to germinate, it is not artificially treated, and it will not even germinate. Soaking the seeds in hot water has no effect, and the water can not get into the inside of the seeds. Mainly after picking, eat the pulp, or pile it to rot, wash it and drain it for preservation. Use clean river sand stratification to promote germination, one layer of sand and one layer of seeds, sand in 5 cm thick, or direct sand and seed mixed accumulation.

Second, sowing seeds

Choose the general deep loose land, ploughing 35cm, rough ploughing, and then machine rotary ploughing to ensure that the soil is fine. Sowing seeds from the ridge, sowing directly according to the planting distance, the row spacing is 30 cm, the plant spacing is 20 cm, the depth is about 10 cm, about 30 jin per mu of seeds, two rows of sowing leave a blank line.

III. Grafting

1. Take scion

Using bud grafting method, select strong branches directly on the mother plant, select full buds, cut obliquely at 1 cm above the bud, with a little xylem, and stop when it is cut to 0.5 cm below the bud. Then cut the bud 0.5 cm below the bud with a knife. The process should be fast, all should be one-size-fits-all, the incision is smooth.

two。 Selection of rootstocks, grafting

Select the seedlings grown from seeding, with a thickness of 0.8 cm and a length of more than 1.2 meters. Cut across the internodes of the rootstock and cut the cambium. Then use the knife to continue to cut vertically in the middle of the previous knife, about 2 centimeters long. Peeling shows a cross crack, gently pry open a little, slowly put the bud scion in, do not break the rootstock skin.

3. Points for attention

After grafting, quickly tie up the scion with transparent film strips to expose the buds, other places can not be ventilated. After grafting, we should pay attention to the growth of other buds nearby, which is easy to compete for nutrients. Grafting should be read quickly, and attention should be paid to aligning the cambium. Check survival about a week after grafting, and can be regrafted.

The main way to raise apricot seedlings is to sow and cultivate rootstocks, and then graft other excellent varieties to make the seedlings more high quality. Or directly plant seedlings. Anyway, it depends on your choice. The market now mainly sells grafted seedlings.
