Abstract
The invention discloses a light matrix seedling method for eucalpytus dunnii. The method comprises the processes, such as matrix preparation, seeding, light matrix preparation, transplantation and management after transplanting. The method comprises the steps of directly seeding eucalpytus dunnii seeds in a seeding matrix disinfected, and then transplanting the seedlings to coco coir after eucalpytus dunnii seedlings are sent up; uniformly mixing carbonized chaff, peat soil and yellow soil according to weight ratio of 5 to 2.5 to 0.5 in a light matrix seedling cup, covering a film and a shading screen after bulging, and out-planting after the eucalpytus dunnii seedlings are 25-30cm and the ground diameter is 2.5-3mm through the management after transplanting. The eucalpytus dunnii seedlings cultivated by the method provided by the invention are thick and strong in seedlings, developed in root, light and convenient to transport and high in survival rate of afforestation, therefore good economic benefits, environmental benefits and ecological benefits can be realized.
Description
Technical field
The invention belongs to the sexual propagation field of E. dunnii, relate to a kind of E. dunnii light ground mass seedling-cultivating method.
Background technology
E. dunnii (
eucalyptus dunnii)for Myrtaceae eucalyptus belongs to seeds, the tropical rain forest of natural distributed in northeast Australia seashore and coastal area and the southeast, Queensland state, be the high megaphanerophyte that a kind of distributing region is narrow, the general height of tree can reach 40 ~ 50m.
E. dunnii is rare summer rainfall pattern, fast growing, seeds that cold-hartliness is strong, is one of China eucalyptus first-selected seeds of moving northward.This species grow speed is fast, and output is high, and material is good, strong stress resistance, especially has stronger tolerance to cold.According to surveying and determination, the wood basic density at tame E. dunnii 10 age is 500 kg/m
3left and right, the E. dunnii big-diameter wood wood basic density of spontaneous growth reaches 800 kg/m
3left and right, and the grain of wood is straight, heartwood pale.Its wood usage is wide, both suitable to paper pulp fiber raw material material, Breeding large diameter timber in also can doing, and is rising seeds.
E. dunnii vegetative propagation difficulty, adopts seedling forestation, seed mainly from Australia, the high and not easily import of seed price.Past E. dunnii nursery adopts yellow soil as seedling medium always, and the root system of yellow soil nursery is less-developed, and weight/power ratio is large, is not easy to transport, is also not easy to afforestation of going up a hill.For solving this difficult problem, seeking a kind of seedling root that is beneficial to and growing and the light seedling raising medium replacement yellow soil being convenient to transport, the development of E. dunnii forest plantation can be contributed to.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of nursery stock sturdy, well developed root system, being lightly beneficial to transport, the E. dunnii light ground mass seedling-cultivating method that survival rate is high.
In order to realize foregoing invention object, technical scheme of the present invention is as follows:
A kind of E. dunnii light ground mass seedling-cultivating method, comprise the operation that the preparation of sowing media, sowing, the preparation of light ground mass, transplanting and transplanting manage afterwards, E. dunnii seed is directly sowed in the sowing media disinfected, after growing E. dunnii seedling, by little transplantation of seedlings in light ground mass seedling-raising cup, cover film and shading screen, obtain E. dunnii to grow directly from seeds nursery stock by transplanting rear management, its concrete steps are as follows:
(1) preparation of sowing media: yellow soil is mixed by 1:1 with clean river sand, sowing media is loaded in 40 cm × 30 cm pore baskets, be the potassium permanganate sterilization of 0.5 % by volumetric concentration, then cover plastic film covering and seal one day, after opening film airing, for subsequent use after water of drenching;
(2) sow: first E. dunnii seed is mixed with a small amount of sowing media, evenly sow again on ready sowing media, each basket broadcasts 1 g seed, after planting spread lid layer sowing media again, to lose seed for degree, to drench water with sprayer, film on arch camber bonnet, keeps matrix moistening;
(3) preparation of light ground mass: by coconut palm chaff: charing husk: peat soil: yellow soil by weight for after 5:2.5:2:0.5 mixes, then adds fused calcium magnesium phosphate 4 kg/m
3, under the sun, cover film stack retting within one month, allow it fully ferment, obtain light ground mass, then make by conventional substrate forming machine the light ground mass seedling-raising cup that diameter is 3 cm, length is 7 cm;
(5) transplant: transplant when the E. dunnii seed until after planting grows 3 pairs of leaves, height of seedling is 3-4 cm: first light ground mass seedling-raising cup is carried out disinfection before transplanting, in light ground mass seedling-raising cup, an aperture is inserted again with small wooden, then E. dunnii seedling is planted into, to drench normal root water, on arch camber bonnet, film moisturizing, finally covers shading screen;
(6) management after transplanting: within after transplanting every 7 days, spray according to a conventional method take that enemy is steady, thiophanate methyl or tpn disease prevention, when E. dunnii seedling grows new root, every 10-15 days sprays composite fertilizer's aqueous solution that volumetric concentration is 0.2-0.5%; After transplanting seedlings after 90-120 days, E. dunnii grows directly from seeds, and seedling height is 25-30 cm, leading thread goes out garden when being 2.5-3 mm.
Above-described sowing manage and protect as every day sprays 1-2 water in basket, with sowing media surface do not do into degree; Grow after 1 pair of leaf until E. dunnii seed, within every 7 days, spray according to a conventional method take that enemy is steady, thiophanate methyl or tpn disease prevention.
The method carried out disinfection to light ground mass seedling-raising cup described in above step (5) is that 0.5 % potassium permanganate solution carries out disinfection to light ground mass seedling-raising cup by volumetric concentration, then cover after plastic film covering seals one day, after opening film airing, transplant again after water 2-3 time of drenching.
Small wooden diameter used in the process of the transplanting described in above step (5) be 1-2 cm, one be whittled into sharp top in shape, the hole depth of inserting out is 1-2cm.
Described in above step (6) take that enemy is steady, thiophanate methyl and tpn three kinds of medicines are used alternatingly.
Compared to prior art, good effect of the present invention is as follows:
1, sowing media of the present invention presses yellow soil: the proportions of river sand 1:1, and it is more flourishing that the side root ratio true yellow cubsoil of the E. dunnii seedling grown is cultivated, and transplanting survival rate significantly improves; If the ratio of river sand used is more than 50%, the fibrous root of the E. dunnii seedling grown is how long again, and during transplanting, easy nest root, affects transplanting survival rate, survive even if transplant seedlings, also can be bad and have a strong impact on seedling growth due to root system development, thus affects survival rate.
2, E. dunnii nursery of the present invention adopts coconut palm chaff: charing husk: peat soil: yellow soil is by weight the light ground mass being 5:2.5:2:0.5, cultivate the E. dunnii seedling survival rate 85% obtained, outplanting rate can reach 75%, nursery stock is more sturdy, root system is more flourishing, and the nursery stock cultivated of true yellow cubsoil is lightweight than ever, be convenient to transport, survival rate is higher.
3, raw material of the present invention is easy to get, proportioning science, comprehensive nutrition, and cost is low, effective, has good economic benefit, environmental benefit and ecological benefits.
