Quick method for orchard establishment by current-year direct seeding grafting of pistachio

Abstract

The invention discloses a quick method for orchard establishment by current-year direct seeding and grafting of pistachio. The method comprises the following steps: selecting pistachio seeds and storing in sand for 40 days before seeding; accelerating germination at the constant temperature of 20 DEG C until the seeds sprout; ridging towards the north-south direction and seeding; ridging according to the fixed plant row space, wherein the ridge height is 30 cm, the upper width is 20-30 cm, and the bottom width is 40-50 cm; punching 8 cm-depth seeding holes with a hole puncher on the ridge according to the 3-4 m plant distance; dibbling 2-3 seeds after germination acceleration into each hole; covering the seeds with fine wet soil and paving a film on the ridge; grating when the root thickness of the plant reaches 0.5 cm; performing T-shaped bud grafting with the scions with full eyes at 5-10 cm away from the ground; pruning rootstock and disbudding after the bud grafting; pinching whenthe scion germinated branch grows to 40-50 cm; and hilling at the trunk root for 40-50 cm. According to the invention, annual orchard establishment by current-year seeding and current-year grafting is realized, and the seedling survival rate is beyond 95%. Thus, basis is provided for large-area popularization and cultivation of pistachio.

Description

Invention field [0001] The invention relates to the field of agricultural planting technology in the field of agricultural biotechnology. Specifically, the present invention relates to a pistachio gardening technology. Background technique [0002] Pistachio, also known as pistachio, is one of the world's four major nut tree species, and is also an excellent tree species for sand prevention and control and water and soil conservation. Pistachio has a long history of cultivation in Xinjiang and belongs to the local characteristic rare fruit trees. It is one of the tree species with great potential for developing characteristic forest and fruit industry in southern Xinjiang. [0003] Pistachio has a good market prospect and high economic benefits. In recent years, the enthusiasm for developing pistachios in Xinjiang is very high. However, due to the high cost of traditional pistachio container seedling cultivation, the difficulty in transporting the seedlings, and the long delay t...
