Description

A kind of short wheel cuts down budding forest drought resisting anti-freezing cultivating management method

Background technology

It is that important ecological seeds are again good environmental protection seeds that the weak points such as paper mulberry wheel cuts down the budding forest seeds, or good paper making raw material seeds.They in our Huanghe valley and areas to the south's growth performance better, now it has been classified as important reproducting tree species.In the higher area of China's latitude, large-area sandy bare land is arranged, when these sandy bare land afforestations, to take into account ecological benefits and economic benefit.These seeds are reasonable alternatives, although these seeds have the cold-resistant characteristic of certain drought resisting, but in latitude higher area and the Northwest, arid severe cold, winter temperature is very low, and they are difficult to survive the winter, and there is great risk in plantation.Past does not have natural distributed, neither their normal region.

The present invention is from the short characteristics of cutting down budding forest seeds cultivation management of taking turns, work out one and be enclosed within China's high latitude area and the short new method of cutting down the budding forest seeds of taking turns of the Northwest's sandy bare land Planting Fast-growing, can improve their drought resisting adaptability, save irrigation cost, solved the preventing freeze in winter problem, for the extensive weak point wheel of building cuts down budding forest in these areas, build large tracts of land paper pulp raw material base and opened up new development space.

Summary of the invention

The present invention proposes the solution of a whole set of system.At first be to cultivate the paper mulberry nursery stock at arid and cold region.The present invention has designed a kind of nursery pond of easy semi-underground structure.Nursery pond north and south layout, width 0.6-3 rice, length is not limit, degree of depth 0.5-1.2 rice.The wall of nursery pond is constructed with brick or other construction material.The North has the semicircular windbreak that protrudes ground, about 10 centimeters slightly above ground level of other three sidewalls, and step and gateway have been built in the south, and middle the block has pavement at the bottom of the nursery pond.The pavement both sides are seedling beds, and seedling bed can be put nutritive cube, cultivate nutrition pot seedling, and the Nutrition Soil of also can mating formation in the seedbed is cultivated cuttage seeding or seed seedling.Can take little shed, covered with plastic film on the nursery pond.This seedling bed is cultivated seedling, and the cuttage of comparable outdoor bed or sowing time two months ahead of time, the high amount of growth in 1 year of sapling is greatly improved.

In order to improve the drought resistance of trees, the present invention proposes a kind of plantation ditch cultivation pattern.According to the seeding row spacing of planning and designing, plant ditch with machinery or hand excavation during afforestation.Plantation ditch wide 40-70 centimetre suitable for reading, ditch bottom width 20-30 centimetre, ditch depth 20-50 centimetre.After the plantation ditch excavates, start seedlings according to spacing in the rows at bottom of trench, dig cave or punching plantation.After the sapling kind was good, the leveling bottom of trench kept the plantation ditch smooth unobstructed, in order to watering and managing.

It is that to plant the paper pulp raw material woods be management objectives that short wheel proposed by the invention cuts down budding forest, in conjunction with the habit of growth of trees, is designed to this short wheel and cuts down budding forest and fell then, fell every year.Behind the annual tree deciduous leaf, no matter large or small, fell from the rhizospheres of the trees 10-20 centimetre part that makes progress without exception.It is smooth smooth that root stubble section is wanted, and phloem can not sustain damage.To rebuild with cutter if any damage, not stay damaged skin to hinder.After felling a week, after the section wound drying, give daubing medicament on the root stubble section, protect, invade with disease prevention.

Cut down the budding forest success at the short wheel of arid and cold region plantation, the cold-resistant antifreeze of winter is crucial.The present invention proposes, and in the winter time the tree root stubble is carried out the antifreezing measures that sandy soil cover heap buried.Before freezing in the winter time largely, in conjunction with the cleaning forest land, the control measures of arrangement plantation ditch, with sandy soil with tree root stubble grave mound heap buried, grave mound pile is wanted 10-20 centimetre above ground level, piles a radius take tree root as the center of circle and is the circular mound of 30-50 centimetre, guarantees tree root stubble safe overwintering.

After thawing to Second Year the earth in spring, Daily minimum temperature is stabilized in 0 degree when above, and tree root stubble grave mound pile is excavated, and rebuild and plants ditch, carries out pouring water spring promotion trees sprout growth.

Beneficial effect of the present invention is:

1, will lack the growing area that wheel cuts down the budding forest seeds extends greatly to north west

2, can utilize the new pulp forestry basis of the large-area sandy bare land construction of arid and cold region

3, ecological construction and economic benefit can be combined, improve masses' enthusiasm of planting trees

4, improve Quality of Seedlings, improve Drought Resistance of Trees, improve water duty, using water wisely is reduced investment outlay

5, short wheel cuts down budding forest trees toothing and survives the winter, and it is simple that the mound envelope is buried method, and expense is low, and is effective

Embodiment

Cut down budding forest paper pulp raw material base at the short wheel of arid and cold region Planting Fast-growing paper mulberry.According to the technical conditions of routine, can not plant paper mulberry in the area that arid is cold, suitable living scope that neither the fast-growing paper mulberry.The short wheel of a kind of paper mulberry that proposes according to the present invention now cuts down budding forest drought resisting anti-freezing cultivating management method and cuts down budding forest paper pulp raw material base at the short wheel of arid and cold region Planting Fast-growing paper mulberry.At first utilize semi-underground nursery pond to cultivate the paper mulberry sapling at arid and cold region, cuttage and seedling culture or the nursery stock in 1 year of seed seedling-raising can reach more than 1 meter, reach the plantation standard.Nutrition pot seedling can arrange Afforestation Time flexibly, except the earth freezed period, all the year round can tree planting, and can be afforestation high quality seedling is provided.

Planting site is carried out planning and designing, and the design seeding row spacing is 1.5 meters * 2 meters, and every mu of plantation 220 strains by 2 meters line-spacing line, utilize the tractor-drawn plough, and the direct motion line is left the plantation ditch.The plantation ditch is suitable for reading wide 50 centimeters, 25 centimeters of ditch bottom width, and 30 centimeters of ditch depths, the spacing in the rows by 1.5 meters in the plantation ditch starts seedlings.Start seedlings and in time pour water afterwards, and according to normal specification requirement tending management.Plantation ditch cultivation pattern can improve Drought Resistance of Trees, reduces irrigation times, improves the availability of water.

Behind the autumn tree deciduous leaf, paper mulberry is carried out the first time fell, no matter arboreal growth is big or small, makes progress 10 centimeters from the sapling rhizome without exception and cut down.Paper mulberry bar strip under cutting down is stacked neatly, delivers to pulp mill, in time peels off bark, and tapa and skewer bar is sent into respectively different workshops carry out process for producing paper pulp.Root stubble after the felling will have the special messenger to check, finds will rebuilding with point of a knife of wound bark, keep section level and smooth, and after the week, after the observation section drying, in time daubing medicament on section is protected wound, pre-disease prevention.

Along with mercury dropped before the earth freezes, the forest land is cleared up, to dig pit to dry branches and fallen leaves residual on the ground and bury, to the plantation ditch safeguard, simultaneously paper mulberry root stubble is done the grave mound heap buried.Grave mound pile is wanted 15 centimeters above ground level, and grave mound pile will be made a radius take tree root as the center of circle and be 30 centimeters circular mound, guarantees paper mulberry root stubble safe overwintering.

Second Year is after the beginning of spring, the temperature rises, is stabilized in 0 when above, and integrated management is carried out in the forest land, paper mulberry root stubble envelope is buried mound to be excavated, make the root stubble return to original state, full maintenance plantation ditch is in time irrigated, by the time after the rudiment on root stubble top is sent, the individual healthy and strong bud of the 2-3 that selects and remain is in time removed unnecessary rudiment, makes the sprouting normal growth.
