CN102265747B - Two-stage seedling raising method using river sand as matrix - Google Patents

Abstract

The invention discloses a two-stage seedling raising method using river sand as a matrix and relates to the field of farming, forestry and gardening. The method comprises the following steps of: a, selecting fine river sand; b, laying a layer of woven bags or newspaper in a seedling raising disc or a flat bottom non-watertight container, laying sterilized river sand with the thickness of 3cm on the woven bags or newspaper, and flattening the surface; c, sowing sprouted crop seeds on the river sand at high density, wherein the distance between the seeds is kept between 0.5 and 1cm; d, covering the sterilized river sand with the thickness of 0.5 to 1cm on the seeds, and finally watering once to flatten the sand surface; e, putting the seedling raising disc or the flat bottom non-watertight container where the seeds are sown in a greenhouse or a plastic tent and other environments suitable for germination and growth for seedling stage management; and f, after seedling cotyledons are opened, transplanting the seedlings into a plug where the matrix is filled when the seedling cotyledons are strongly green and plump, lifting the woven bags from one side in the process of raising the seedlings, loosening the river sand, slightly lifting the seedlings, keeping seedling root systems complete, preventing the seedling root systems from being damaged, forming a hole in the center of the matrix in the plug through bamboo chopsticks, putting the seedlings into the hole, compacting the matrix, thoroughly watering, and managing according to the growth environment conditions of the seedlings.

Description

River sand is made the two-section growing seedlings method of matrix

Technical field:

The present invention relates to agricultural gardening field, specifically is the two-section growing seedlings method that a kind of river sand is made matrix, is particularly suitable for the less crop seedlings of thousand kernel weight such as vegetables, flowers, forest, medicinal material and tobacco.

Background technology:

Substrate seedling both had been fit to peasant household's small size grows seedlings, and is fit to large-scale industrialized growing seedlings again, at present in China's widespread usage.But also exist aborning be short of seedling, top shell, not too neat, the shortcomings such as also revealing seed accidentally easily of watering of emerging.

Summary of the invention:

The purpose of this invention is to provide a kind of river sand and make the two-section growing seedlings method of matrix.

In order to solve above technical problem, the invention provides a kind of method that is particularly suitable for the less crop seedling of thousand kernel weight such as vegetables, flowers, forest, medicinal material and tobacco, river sand is made the two-section growing seedlings method of matrix.

Technical scheme of the present invention is following:

River sand is made the two-section growing seedlings method of matrix, it is characterized in that comprising the steps:

A, select thin river sand, it is subsequent use to clean after 10 minutes the drop branch that anhydrates with 0.3% disinfecting solution of potassium permanganate;

B, in seedling-cultivating tray or the flat container that leaks, shop one deck woven bag or newspaper at woven bag or the thick sterilization river sand of newspaper upper berth 3cm, are scraped plane surface;

C, the sowing of the big density of the crop seed after vernalization ground on river sand, distance remains between 0.5～1cm between the seed;

D, on seed, cover the thick sterilization river sand of 0.5～1cm, water primary water at last again, make the sand face smooth;

E, be placed on the seedling-cultivating tray of having broadcast seed or the flat container that leaks suitablely in greenhouse or the booth germinate, the environment of growth carries out seedling management;

After f, seedling cotyledon were open and flat,, plumpness when the cotyledon look dark green can be transplanted in the cave dish that installs matrix, during lifting, Yi Bian from beginning; Lift woven bag or newspaper, make river sand loose, gently carry seedling again; Can keep seedlings root complete injury-free, disk base material central authorities insert a hole in the cave with bamboo chopsticks, put into seedling; Compacting matrix, water permeable after, the environmental condition management of pressing growth of seedling gets final product.

The invention has the beneficial effects as follows:

1, avoided that conventional substrate exists in growing seedlings be short of seedling, top shell, irregular, the shortcomings such as revealing seed accidentally easily of watering of emerging.

2, manageable, because in river sand, grow seedlings, damage by disease and insect is few, does not need fertilising, keeps moistening as long as water.

3, the river sand seedling density is big, and floor space is little, and temp. and humidity is easy to control, and seedling is healthy and strong.

4, the river sand raw material is prone to get, and is cheap, and production cost is low, operates simple and easy.

Embodiment:

The sowing of the big density of crop seed after vernalization ground in river sand, by the time seedling cotyledon open and flat after, be transplanted in the disk base material of cave, like this two-section growing seedlings can avoid that conventional substrate is short of seedling, shortcomings such as top shell, not too neat, the dew seed that waters accidentally easily of emerging.

River sand is made the two-section growing seedlings method of matrix, carries out according to following steps:

A, select thin river sand, it is subsequent use to clean after 10 minutes the drop branch that anhydrates with 0.3% disinfecting solution of potassium permanganate;

B, in seedling-cultivating tray or the flat container that leaks, shop one deck woven bag or newspaper at woven bag or the thick sterilization river sand of newspaper upper berth 3cm, are scraped plane surface;

C, the sowing of the big density of the crop seed after vernalization ground on river sand, distance remains between 0.5～1cm between the seed;

D, on seed, cover the thick sterilization river sand of 0.5～1cm, water primary water at last again, make the sand face smooth;

E, the environment that is placed on suitable germinations such as greenhouse or booth, growth to the seedling-cultivating tray of having broadcast seed or the flat container that leaks carry out seedling management;

After f, seedling cotyledon were open and flat,, plumpness when the cotyledon look dark green can be transplanted in the cave dish that installs matrix, during lifting, Yi Bian from beginning; Lift bag weaved, make river sand loose, gently carry seedling again; Can keep seedlings root complete injury-free, disk base material central authorities insert a hole in the cave with bamboo chopsticks, put into seedling; Compacting matrix, water permeable after, the environmental condition management of pressing growth of seedling gets final product.

More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification is merely preference of the present invention, is not used for limiting the present invention, under the prerequisite that does not break away from spirit and scope of the invention; The present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
