Abstract

The invention provides a method for setting a seed bed inside a tea nursery, which is essentially characterized in that: (1) the seed bed is set to be kyphosis-shaped, that is, high in middle and lower in both sides; (2) a shading trellis is arranged above the seed bed; (3) yellow soil is spread on the border field and acidity of soil is maintained. The method has the advantages that: (1) the border field of the seed bed is kyphosis-shaped and no water is accumulated on the border field, which ensures full development of seedling root system and high survival rate of seedlings. In addition, uneven border field is favorable to ventilate, thus ensuring fast growth and nursery of the seedlings, so the method is applicable to the cuttage method of short sprout and shoot; the yellow soil is spread on the border field, which ensures that the acidity of the soil on the seed bed is maintained, which is applicable to the growth of new root and survival of the seedlings; a shade net is used for shading to avoid exposure in sunlight from July to August, thus greatly improving the survival rate of the seedlings.

Description

Tea tree nursery garden seedbed method to set up

Technical field:

The present invention relates to new agricultural technology, specifically is tea tree nursery garden seedbed method to set up.

Background technology:

1. the seedbed in existing tea tree nursery is the horizontal seedbed, and its shortcoming is that the easy dehydration in both sides, seedbed causes arid, and the easy ponding of mid portion causes the mashed dead seedling of root easily, is in the seedling at middle part, seedbed, because ventilative ventilation is poor, also easily by vexed and fall leaves; 2. the not strict acid soil of selecting for use of nursery soil is unfavorable for sprouting new root and growth of seedling.

Summary of the invention:

The objective of the invention is for overcoming the deficiencies in the prior art, and a kind of tea tree nursery garden seedbed method to set up is provided.

The object of the invention realizes by following technical proposals:

The present invention includes and set up the seedbed, soil disinfection, basal dressing, unlike the prior art be:

(1) turtleback shape is arranged in the seedbed, and promptly the middle part is high, and both sides are low;

(2) top, seedbed is provided with the frame that shades;

(3) furrow face shop yellow soil keeps soil acidity.

The wide 1.3-1.5m of described turtleback shape seedbed furrow, the positive high 18-20cm in middle part, the high 10cm in edge, seedbed makes furrow cross section curved (turtleback shape).

The described frame that shades, shading rate are 75%.

Described shop yellow soil is after the seedbed is put in order well, and the thick loess formation of furrow face shop one deck 5cm keeps soil acidity, helps new root and produces and seedling growth.

Advantage of the present invention is:

Seedbed furrow face is a turtleback shape, and the furrow face is ponding not, helps ventilatedly, makes the seedling root zoon, and seedling growth is fast, the plant percent height, and outplanting rate improves 15-20%, is specially adapted to short fringe epicormic branch cuttage method.

Embodiment:

(1) sets up the frame that shades

Set up permanent cool canopy frame, be stake (rugosity 12cm * 12cm), length 240cm with concrete column, imbed 50cm in the soil, pillar spacing 4m * 4m, strain anyhow with No. 8 iron wires the pillar top, strain anyhow with No. 12 iron wires the centre again, and the shady sun net with 75% shading rate covers then.

(2) seedbed is set up

Seedbed length base area block size and deciding, generally long 20～30m, wide 1.3～1.5m, high 10cm, aisle 20cm harrows in the seedbed in the thin process the high about 15cm of heap slightly in the middle of the furrow, and past then both sides tilt gradually, and shape is the curvature of the spinal column seemingly.

(3) soil disinfection

Select for use tpn, carbendazim, clean any one of native bacterium a slice to carry out soil disinfection (working concentration is by explanation), convert the water pouring and execute.

(4) basal dressing

The fertilizer that every mu of sealing fertilizer 150kg or 1000kg become thoroughly decomposed.

(5) shop yellow soil

The thin yellow earth cubsoil that choice structure is good, the soil is porous, ventilation is good (table soil part is not), be layered on the seedbed, the thickness of shop yellow soil is 5cm, earlier drench, grab cubsoil broken, and after harrowing into turtleback shape, load onto bundle rollback on the seedbed with cylinder of long 60cm, diameter 10cm, heavy 15kg and move 4～5 times, the seedbed can be compressed, the degree of packing in seedbed has shallow seal to be advisable with the seedbed that press...withes one's finger.

Claims

1, tea tree nursery garden seedbed method to set up comprises and sets up the seedbed, soil disinfection, and basal dressing is characterized in that:

(2) top, seedbed is provided with the frame that shades;

(3) furrow face shop yellow soil keeps soil acidity.

2, the method for claim 1 is characterized in that: the wide 1.3-1.5m of described turtleback shape seedbed furrow, the high 18-20cm in middle part, the high 10cm in edge, seedbed.

3, method as claimed in claim 1 or 2 is characterized in that: for the starting point height is followed successively by 20cm → 18cm → 16cm → 14cm → 10cm, the furrow cross section is the arc window shape with the center in described turtleback shape seedbed.

4, the method for claim 1 is characterized in that: the described frame shading rate that shades is 75%.

5, the method for claim 1 is characterized in that: the described yellow soil bed thickness of step (2) 5cm.
