2. Seed selection is the key link, which is related to the high yield of local apricot trees. After selecting the seeds, in order to ensure the emergence rate in spring sowing, the seeds should be layered in winter, that is, the seeds should be stored in sand.
After mixing the seeds, first spread a layer of wet sand at the bottom of the pit, and then put the mixed seeds in into the pit until the pit mouth is about 30 cm, and the top needs to be filled with wet sand. Finally, build a mound outside the ground, and the height of the mound should be appropriate to prevent water accumulation.
Sowing here is divided into spring sowing and autumn sowing, which need to be adjusted according to local climate conditions. The methods of sowing can basically take the form of ditching and occupying sowing. Ditch first, the ditch width is appropriate, and a certain row spacing and plant spacing are maintained.
4. Soil management is very important for planted apricot trees. In autumn, it is necessary to turn the soil about 20 cm, keep the soil fully ventilated, and increase the soil fertility, which is conducive to the better growth of roots.
5. Rational fertilization can improve the fruit setting rate of apricot trees. Fertilizer should be mainly organic fertilizer, with some diammonium added. In autumn, ditch can be used to apply base fertilizer. However, topdressing requires two topdressing operations before flowering in spring and after apricot trees bear fruit. The basic topdressing should be mainly urea fertilizer, combined with some two-pressure and shallow furrows, which can promote fruit setting and fruit development.
6. Infiltrate water once before germination to meet the needs of apricot blossom and growth. After flowering, irrigation should be done once to improve the fruit setting rate and fruit quality. Secondly, it is shaping. When modeling, it should conform to the growth habits of apricot trees, adopt natural round-headed modeling and make some manual adjustments to ensure that the growth of apricot trees is more in line with its growth habits. Second, wintering protection is also very important for apricot trees. Common methods include painting, turning over soil and wrapping grass to prevent excessive damage to bark caused by low temperature.
Apricot is a positive tree species, with strong adaptability, deep root system, photophobia, drought tolerance, cold tolerance and wind resistance, and its life span can reach more than 100 years. It is the main cultivated fruit tree in low mountain and hilly areas.
