Embodiment 1

[0023] Seed treatment: select plump pistachio seeds produced in the same year, and perform sand stratification for 40 days before sowing. Then germinate at a constant temperature of 20°C until the seeds are white and can be sown.

[0024] Sowing: In late March, select plots with high fertility, good water permeability and air permeability, and sow in ridges, with the ridges facing north-south; according to the row spacing of planted plants, ridges are 3×4m or 4×6m, and the ridge height is 30cm, and the upper width is 20- 30cm, bottom width 40-50cm; use a hole puncher with a diameter of 10cm to drill a sowing hole with a depth of about 8cm on the ridge according to the distance between the plants of 3-4 meters, and plant 2-3 seeds in each hole after germination, and cover the thickness of about 2cm fine wet soil, and then spread film on the ridge.

[0025] Post-sowing management: Pistachio seedlings begin to emerge about 10-12 days after sowing, and care should be taken to rel...

Embodiment 2

[0030] Cultivation environment: suitable for pistachio in annual frost-free period ≥ 180 days, annual ≥ 10 ℃ effective accumulated temperature above 3700 ℃, annual growing season rainfall less than 200mm, growing period sunshine hours above 1500h, extreme low temperature not exceeding -23 ℃ In the area of ​​cultivation and growth, choose light sandy loam, sandy soil and gravel land with a soil pH value of 7-8 and a groundwater level below 4m for planting.

[0031] Seed treatment: choose fresh and plump seeds with a germination rate of more than 90% produced in the current year for treatment. Seeds need to be soaked before sand storage. When soaking the seeds, soak them in clear water for 24 hours, and remove the unfulfilled seeds floating on the water surface. After soaking the seeds, soak and sterilize them with 0.3% potassium permanganate for 15 seconds, remove the seeds and control the water, and then carry out sand storage.

[0032] Sand stratification: Choose a leeward,...

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 when the 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

field of invention [0001] The invention relates to the technical field of agricultural planting 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 four major nut tree species in the world, and it is also an excellent tree species for sand control and soil and water conservation. Pistachio has a long history of cultivation in Xinjiang, and it is a rare fruit tree with local characteristics. It is one of the tree species with great potential for the development of characteristic forest and fruit industry in southern Xinjiang. [0003] Pistachio has good market prospects and high economic benefits. In recent years, the enthusiasm for developing pistachio in Xinjiang has been very high. However, due to the high cost of traditional pistachio container seedling cultivation, the transportation of seedlings is difficult, and the...
