Silver almond trees are one of the world's most precious species, with a value of appreciation, economy and medicine, their vitality and foliage, their ease of marriage, their breeding and integration, and their quality material for the production of basin views. Silver almonds usually start at spring break, and today we'll show you how silver almonds grow, how silver almonds grow。
The technique of breeding silver almonds:
Cultivation
(1) selection of nursery grounds
It is chosen to be a breeding ground where the ground is flat, the back wind is sunward, the earth is thick, the soil is estranged and fertile, and water is well drained. The nursery area is fully reclaimed, and each acre is fed with calcium phosphate in a corrugated cortex of 2,000 to 3,000 pounds。
(2) drumbing and seeding。
The seeding can be done immediately after the harvest in the autumn, without the need to sprout. In the case of seeding in the spring, seedlings should be carried out. Precipice remove sanded seeds and place them in plastic sheds or greenhouses, be careful to be wet and plant them after more than 60 per cent of the nucleus。
Silver almond seeding can be broadcasted, soaked, soaked and soaked. The seeds should be placed north-south, directed in the same direction, and the embryos should be down, and the seed stitches should be vertically or parallel to the ground, with a steep horizontal line, so that the seeding rate is high, the roots are normal and the seedlings grow strong. The soil is sowed at a distance of 810 c m. And covered with plastic membranes, which can be removed in time for the seedlings to be released, allowing for early and clean。
(3) shrimp management
The application of fertilizers, which are short-lived, have stopped growing early and have underdeveloped roots, has a significant contribution to their growth. Fertilizers could be applied once in mid-april, mid-may and mid-july, with an annual application of 1012 kg of urea per acre. Fertilizer should be applied in such a way that it is not too close to the seedling to burn the leaves。
Silver almonds are afraid of floods and drought, so drainage and irrigation should be done. Silver almond seedlings grow slowly, are less competitive with weeds, and are required to mower in time。
2. Cultivation
Land with a good soil sterilisation and drainage is selected for foot fertilisation, and the ground is dug deep and then made into a sapling bed, which is 1 - 1. 2 metres wide and varies in length。
(1) eclipse
Select the one-three-year-old branch from the strong silver almond tree, cut into a 10-15 cm long slot, treated with root powder at the lower end and immersed for 10 seconds。
(2) management
Intubation in the middle of march, with a line range of 8-10 cm and a length of 3-5 cm, should be carried out, with 2-3 sprouts on the ground. The plug is filled with water in time. The open-pit piping should contain an arch plastic film shed to keep it warm and humid, with temperatures around 20°c and water twice a day。
After more than 40 days of plug-in, the root can take root, and the light will gradually increase, with the new branch growing to 3-4 cm, so that the plant can be replanted, the choice of the shade can be removed and the sun kept wet. The activity rate can be over 90 per cent。
