I don’t know if you have heard of date palm seeds. If you haven’t heard of them, please see the introduction given by the editor below.

Date palm planting technology

When is the best season to plant Canary date palms?

The seeds that have just been picked should be allowed to dry naturally, and should not be exposed to the sun. After drying, remove the seed coat. If you want to prevent insects, soak them in dichlorvos for 20 minutes and then dry them. Canary date palm can be planted all year round, but it is best planted in spring and summer.

Treatment and sowing of date palm seeds

① Seed treatment: After harvesting mature seeds, they should be treated in time to remove the peel and pulp. Pour the seeds into a container filled with 1:500 thiophanate-methyl or carbendazim solution and soak for 30 minutes, take them out and soak them in clean water for 24 hours, then sow them and germinate them.

② Seeding and germination: Use river sand, coconut bran and a small amount of loess in a certain proportion to make a moisturizing and transparent sowing matrix, sow the seeds in a clay pot, seedling screen or ground bed, cover with a thin layer of river sand, and shade to moisturize and germinate. When the seeds turn white, put them in a nutrient bag with good permeability (the specification of the nutrient bag is 18cm×9cm) for cultivation. The nutrient soil is 4 parts of sand loam, 1 part of mushroom soil, and 1 part of rice ash. A layer of film is laid under the nutrient bag. Sow one seed in each bag with the hilum facing down, and then cover with sand with a thickness of 1.5cm.

Seedling management

① Shade and moisturize: After the white seeds are placed in the nutrient bag, a 50% shade shed should be built to minimize sun exposure, cool down and moisturize. In winter, windproof and heat-insulating measures should be taken.

② Fertilizer and water management: When the seedlings grow to 1-2 leaves, the nutrients stored in the seeds are basically exhausted. At this time, spray with 0.5% urea solution or compound fertilizer solution every 15 days. You can also combine spraying with 0.1%-0.2% potassium dihydrogen phosphate or urea solution for foliar topdressing to promote growth. Keep the nutrient soil permeable and not waterlogged to avoid root rot and seedling death.

③ Disease control: Common diseases of Canary date palm seedlings include leaf spot, anthracnose, blight, etc. The main control measures are: first, prevention is the main method. Before the disease occurs, spray with 1:1:100 Bordeaux liquid; second, if the disease has occurred, spray with 500-700 times dilution of thiophanate-methyl (or ridomycin, mancozeb) in turn, and cut off the infected diseased leaves in time and burn them in a centralized manner; second, strengthen fertilizer and water management, increase the application of phosphorus and potassium fertilizers, make the plants grow strong, and improve the disease resistance of the plants.

Cultivation management

1. Soil selection: The growth of Canary date palm is not very demanding on the soil, but for garden nursery production, fields with convenient transportation, deep soil, rich in organic matter, and convenient drainage and irrigation should be selected.

2. Land preparation and ridge making: After selecting the soil, dig drainage ditches around to prevent soil waterlogging. Land preparation and ridge making, ridge width 130cm, ditch width 20cm. Plant in a "品" shape, dig holes with a row spacing of 100cm×150cm (or 100cm×100cm), 30cm deep and 30cm in diameter, add 0.5-1kg of decomposed farmyard manure or 0.5kg of organic fertilizer to the bottom of the hole, mix well, and then return the soil appropriately.
