Abstract
The invention discloses a cassia siamea seedling raising method for quick propagation and forestation. The seedling raising method comprises the following steps of firstly, performing deep ploughing and thorough harrowing to crush soil, disinfecting, and arranging a seedling bed; disinfecting seeds for 1.5 to 3 hours before sowing in March, sowing the seeds according to the amount of 3 to 5g/m<2>, and building a shed for shielding light; after sowing, watering at the interval of 3 to 5 days; enabling a young seedling to grow seed leaves 28 to 32 days after sowing, transplanting when the average seedling height is greater than or equal to 3cm, and mixing 75 to 85 parts of humus soil under broad-leaved forests, 12 to 18 parts of farm organic manure and 4 to 6 parts of calcium superphosphate to form nutrient soil; after transplanting, watering at the interval of 1 to 2 days; applying 0.8-1.5% of urea nutrient solution at 10th to 15th days after transplanting, and applying again at the interval of 15 to 25 days, and removing the shed 30 to 40 days after transplanting; taking the seedlings out of a nursery garden, and planting into a forest 55 to 65 days after transplanting when the average seedling height is greater than or equal to 12cm, and the ground diameter is greater than or equal to 0.15cm. The method has the advantages that the raising time of the cassia siamea can be effectively shortened, the forest can be formed when the age of seedling is one hundred days, the seedling has strong stem and branches, and the germination is regular; during transplanting, the damage to main roots and removal of tops are not needed, the survival rate of transplanting is high, the seedling recovering period after transplanting is not needed, and the growth is quick; after the seedling is planted for one year, the average seedling height is greater than or equal to 2.5cm, and the average ground diameter is greater than or equal to 4.6cm.
Description
Technical field
The invention belongs to cassia siamea raising technology field, be specifically related to the cassia siamea seedling-cultivating method of a kind of fast breeding afforestation.
Background technology
Cassia siamea (
cassia siamenlam) belong to Caesalpiniaceae half deciduous tree seeds, originate in south of Yunnan and South Asia, torrid areas, Southeast Asia, there is introducing and planting torrid areas, the whole world.Cassia siamea strong adaptability, has wind resistance, drought-resistant characteristic, trunk Gao Zhi, and growth rapidly.The flaxen inflorescence of full-bloom stage in autumn, in tree crown open-top, is excellent Woody flower, is also the pioneer tree species that medium fertility is planted trees with " four is other " suitable for afforestationly.In addition, the hard high-quality of cassia siamea timber, texture variations is enriched, and beautiful appearance is generous, belongs to Precious Timber Species, has very high value of exploiting and utilizing.
In traditional cassia siamea raising technology, the seedling age nursery stock of 1 year is generally adopted to afforest.Usual more than the 30cm of height of seedling, main root is flourishing, and seedling bar children is tender, needs main root during plantation, goes to seedling top, is not easy to survive, and seedling growth seedling-slowing stage is longer, and after nursery stock germinating, growth rate is slow, to plant after 1 year height of seedling only at about 1.3m, average leading thread 3.2cm.Seedling cost is higher, does not utilize large-scale promotion.Meanwhile, because outplanting gets seedling difficulty, cost of transportation raises, and brings certain restriction also to the popularizing planting of cassia siamea.The present invention aims to provide the cassia siamea seedling-cultivating method of a kind of fast breeding afforestation, provides technical support for advancing the fast development of Precious timber industry.
Summary of the invention
The object of the present invention is to provide the cassia siamea seedling-cultivating method that a kind of fast breeding is afforested.
The object of the present invention is achieved like this, and the cassia siamea seedling-cultivating method of described fast breeding afforestation comprises wholely, sowing, seedling management, transplanting, Managing small seeding and go out garden operation, specifically comprises:
A, whole: to sowing ground thin rake of deep ploughing, to break up the clods and sterilize, managing and sow seedbed;
B, sowing: annual sowing in March, seeds before seeding soaking disinfection 1.5 ~ 3h, then by 3 ~ 5g/m
2seeding quantity broadcast sowing, then on seedbed, build shed shelter from heat or light;
C, seedling management: after planting water 1 time every 3 ~ 5d, keep ground moistening;
D, transplanting: after planting 28 ~ 32d, after seedling eldest son leaf grows, be transplanted to during average height of seedling >=3cm in nutrient container, and under Nutrition Soil adopts the broad leaved forest of 75 ~ 85 parts, humus soil, the farm organic fertilizer of 12 ~ 18 parts and the superphosphate of 4 ~ 6 parts mix;
E, Managing small seeding: water 1 time every 1 ~ 2d after transplanting, keep ground moistening, and after transplanting, 10th ~ 15d starts the urea nutrient solution imposing 0.8 ~ 1.2%, after this executes 1 time every 15 ~ 25d, and after transplanting, 30th ~ 40d removes shed;
F, go out garden: 55 ~ 65d after transplanting, as average height of seedling >=12cm, during leading thread >=0.15cm, go out garden afforestation.
The method of the invention effectively shorten cassia siamea nursery, go out the garden time, seedling age one hundred days can be afforested, now more than height of seedling 12cm, and stem stalk is strengthened, and lignification is moderate, sprout neat.Planting density 1.5 × 1.8m, without the need to injuring main root, also without the need to going to top, improve transplanting survival rate of nursery stocks, not having seedling-slowing stage after plantation, direct growth, growth rapidly, plants average height of seedling >=2.5m after a year, average leading thread >=4.6cm.In addition, shorten after seedling age, it is easy that outplanting gets seedling, significantly reduces transport, transplanting cost, after seedling growth can also between plant corn, beans etc., improve land utilization rate, remarkable in economical benefits.Seedling-cultivating method simple possible of the present invention, is easy to grasp, suitable large-scale promotion application.
