Construction of the mancron fruit nursery
Technology for seedlings
(ii) non-sexual reproduction: 1 - embrace: digging the roots of a robust parent tree, cutting up 10 - 15 cm and 1 cm or so of a pedestal, with a large head on top of a pedal below the ground surface of 2 - 3 cm, pouring water, 15 - 20 days after which the roots begin to hatch, with a strong embryo selected and the rest of the whole plaster removed for its growth. 2. Root seedlings: the two seasons of spring and autumn open loops at 1 m from the mother tree, severing the roots and promoting their natural division. 3. Retention of seedlings: after digging up the tree, water is poured once, using the roots left in the subterranean section for seeding。

Man crown fruit
It's a child-free coronary fruit, with leaves down, trees up to 8m, with a chest size of 3 cm or more, barks brown, twisted and fractured. It's a very good wood-fed tree that is unique to my country. It is very resilient to the soil, is thin, saline-resistant, is resistant to cold and is safe to winter at 41. 4°c. It is extremely resilient to drought and has scattered trees in areas where annual rainfall is only 150 mm, but it is impenetrable, afraid of the wind and unsuitable to plant in low-lying areas, heavy salin and unsettled sand. According to the national “1105” development plan, 1 million acres of energy forest were planted on a pilot basis throughout the country in 2007, and 200 million acres of energy forest will be cultivated by 2020, producing 6 million tons of biodiesel, which will gradually change the country's energy structure and reduce dependence on oil. So, as the most important source of energy in the north of the country, the tree species have great development prospects。
Technology for seedlings
(1), spring: 1, seed: before planting in the spring, seedlings must be sprung in the seeds that have been selected (hand or water selection), with two methods: a, mixed sand burying: before the winter soil freezes, the wind is chosen to drain to the sun, the bottom pit is dug to a depth of 0. 3 m, the length of the pit is sown to a quantity, the seed is sprung with 2 to 3 times wet sand, 10 to 15 cm above the ground, with sand covered with soil slightly above the ground, 10 to 15 days before the annual planting, 10 to 15 days before the wind is sprung, 20 days before the wind is sprung to the sun, natural sprung, 3 to 4 times per day, with a small amount of water being sprayed in order to remain humid, together with grass covers, while around 10 per cent of the seeds are sprung: b, warm water is sprung 30 to 40 days before the spring, seed is sprung to soak down to the sun for about 20 days, and soaks to the bottom 25 times before the sun is sprung in room。
