Description

Cutting forset-plantation method of poplar

The present invention relates to the cultivation method of a kind of willow.

Today that China's ecotope is seriously damaged, concede the land to forestry to mention on the new schedule.Large tracts of land afforestation, the seedlings that often adopt 2-3 to give birth to become a plantation.In the field planting stage, the condition that planting stock survives mainly is a moisture content, and to large tracts of land afforestation, it is big that seedlings are planted freight volume, is difficult for insulation, and it is big that water requirement is advanced in field planting, is difficult for keep-alive, root system damage during lifting, and influence survives.Especially transplant the seedlings of 2-3, limb is exposed on the ground entirely, and emission is big, be completely cured not newborn before suction not enough, imbalance of supply and demand just appears, cause the physiological function imbalance and death.And a seedlings cultivation to educate the time long, the greening progress is slow, large tracts of land cost of forestation height.

The object of the present invention is to provide the cultivation method of a kind of willow, cost is low, survival rate is high.

The present invention adopts the cuttage cultivation: autumn is at the underground cuttage hole of having trained; With bright of the annual seeds bred, before the bud bud is sprouted, mid portion is cut into the long graft shaped seed piece of 13-14cm; The bundled tip of cuttage bar that cuts put into down heel in the hole and carry out nursery stock and heel in; Before the cuttage water is put in cutting and soaked 12 hours, in 0.05% root element solution, dip in, can carry out field planting; When seedling is unearthed wholeheartedly two leaves, carry out final singling; The twig that cuttage seeding bears then gets rid of the children the tender phase without exception.

The concrete step of the present invention is:

1, trained the cuttage hole.Preferably the autumn is trained hole, and the spring is inserted seedling.Method is with digging the stubble shovel, by estimating equidistantly to dig into dark 20cm, the outer real heap hole of pine in garden, the side of piling 30cm * 30cm steamed bun shape, i.e. soil moisture conservation cuttage easily again, and survival rate height.

2, shear the cuttage bar.With bright of the annual seeds bred, before the bud bud is sprouted, remove rare section of root nodal bud, remove a branch immature position slightly again, mid portion is cut into the long graft shaped seed piece of 13-14cm.

The method of cutting is: with special-purpose profit shearing, otch is wanted smooth and is not broken.Distance first bud bud 1cm place's truncation is got in upper end (referring to head position slightly), and the lower end is cut into sharp pointed, so just is cut into the graft shaped seed piece of a flat point.

3, nursery stock is heeled in.With cuttage bar 50 or 100 a bundles that cut, the tip is put into down and is heeled in hole or sombre place, and layer bundle layer is husky, buries the temperature difference in the heap, remains on about zero degree and is advisable, and the highlyest can not surpass 5 ℃ of degree above freezing.And watered a water every 5-7 days and keep moistening.

4, cottage method.Regional northeastward soil thawed and reached deeply about 15cm time, before the anti-slurry in ground, can skilfully use anti-pulp-water like this and guarantee survival rate, and other area can be carried out at the afforestation favorable season.

Before the cuttage, the bundled water of putting into of will transplanting a cutting soaked 12 hours, can not surpass 20 hours, made nursery stock suction moisture content, favourable surviving.Soaked to pull out and got rid of clean table water, in 0.05% root element solution, dipped in, can carry out field planting.The field planting gimmick is: vertical, reliable, be inserted in the middle of the native hole fast, and make to transplant a cutting and combine closely, like this survival rate height with soil.Prevent that standoff effects is emerged between a slotting slowly rolling branch formation seedling, the soil.Consistent on transplanting a cutting with ground level, can not exceed too high.

5, insert the back management.Key is a moisture management, except that catching soil moisture, will suitably water when meeting the sky drought, because the cuttage nursery stock is during integral body is all placed into the soil, tangible drought resisting effect is arranged, and generally needn't water.But must often observe the rooting of cuttings situation, grasp surviving dynamically.

Inserting the 15-30 days rooting of cuttings in back.Root system gos deep in the soil under the cuttage soil layer, and at this moment surviving has just had assurance.When seedling is unearthed wholeheartedly two leaves, carry out final singling, every hole only stays a strain, carries out the root ridging when growing up to 70-100cm when high, and growth helps taking root.

6, change to move back and very break bud off with the fingers and thumb.The twig that cuttage seeding bears then gets rid of the children the tender phase without exception, becomes Du Luxuriant.After 1 year, the twig that goes out below the tree crown all can be got rid of the children the tender phase every year.Change that to prune to breaking the bud benefit off with the fingers and thumb be the scar that promptly do not fall, reduce nutrient and run off, do not delay the growth of tree, can improve the straight degree of tree again.Change old in the past branch and moved back wooden fork, stay easily and die for the sake of honour, form mashed heart tree, or because to move back wooden fork late excessively, branch forth, cause trunk to be distorted and change shape, form " little old " tree, influence is become a useful person, the reduction benefit.

7, in time prevent vexed bud, can improve survival rate more than 5%.Do not emerge after planting, have plenty of because vexed bud causes.Reason is that cuttage is dark excessively, ground high humidity oxygen uptake deficiency; Or two bud buds of 1-2 are imbedded in the soil during slotting seedling, make its temperature deficiency of sprouting.Because being short of seedling that vexed bud causes accounts for about 10%, must in time solve.

To the slotting seedling that expires and be not unearthed, the people carefully and neatly holds up one by one, does like this and can bring back to life vexed bud seedling more than 5/10ths, in addition small and weak seedling is wanted application of organic fertilizers, promotes that seedling is neat.

8, a ground is encrypted and is cultivated preliminary seedling.In the afforestation plot, by 15% of cuttage seeding,, plant in order to benefit and to be short of seedling at two transplanting stock intermediate cryptographic cuttage, one strain preliminary seedling, carry out making transplanting stock and benefit to plant seedling growth basically identical so simultaneously, stand in great numbers neatly, save the soil again.And a ground transplanting survival rate height, the shortcoming of two class seedlings seldom appears.

The advantage of cutting forset-plantation method of poplar of the present invention is:

1, survival rate height.It mainly is moisture content that planting stock survives condition.Cuttage afforestation is planting stock all to be imbedded underground, and its face that distributes has only the top of cutting less than 1 square centimeter.The moisture absorption face that it is embedded in the underground is more than 40 square centimeter, is 1/40th ratio.And freight volume reduces and to have overcome the drawback that seedlings are planted the moisture content deficiency, therefore can improve more than the survival rate to 85%, lives as this part seedling of vexed bud being held up again, and also can improve to survive 5-8 percentage point.

2, growing way is good, and material is good.The transplanting process is removed in disposable cuttage field planting from, unslow seedling process.When the work of growing seedlings of testing factually that cuttage field planting and seedlings plant is carried out the same period, the two 3 years growing way basically identical, seedlings trip out transplant planting at the beginning of the 4th, and transplanted seedling earned a bare living in 1 year, slightly increased in 1 year, recovered normal on the 3rd year.And cuttage seeding is delayed the seedling process owing to not transplanting, and every year, this section was long fast with regard to surpassing big transplantation of seedlings all at steady normal growth.Add to change and prune to breaking the skill method of repairing of bud off with the fingers and thumb, the phase of becoming a useful person also will shift to an earlier date.

3, reduce cost.Seedlings are planted, every sapling will be spent 1-2 unit, add that expenses such as transportation must 1-2 unit, average every is not less than 2 yuan, and the cuttage cultivation, and one annual bright (market price 1 jiao 5 minutes) is cut into about 5-6 section, can make a strain for every section, cost has only 4-5 to divide money, plants than seedlings and reduces cost 40 times, and benefit is very considerable.

4, save land used 1-2 doubly, the time shifts to an earlier date 2-3.The kind bar that cuttage is used is annual getting final product, and drops into construction than using seedlings to shift to an earlier date 2-3, thereby saves land used 1-2 doubly.

5, save recruitment.Cuttage is made 10,000 strains, and only with 10 work days, 4 on whole ground plants 3 of seedlings, waters 3, does not meet spy's head in the year of drought and needn't water.Save recruitment.

6, advanced motherland's greening process greatly.6 at village level units according to investigations adopt seedlings to plant and annually can finish 400 mu of left and right sides tasks a planting season, can make about 10,000 strains by 1.5 * 1.5 meters/strain calculating.If the employing cuttage, with same work day, a season can be finished the task in 25 years.
