Abstract

The invention provides a method for improving the germination rate of coixseeds, which comprises a material preparation period, a seed and culture medium treatment process and a seed later-stage management process. In the method, by treating seeds with culture solution by stages, controlling culture environment, using common fertilizer of farmers as a main chemical agent and using a farmer controllable chemicophysical method, the germination environment of the coixseeds is improved and growing conditions suitable for germination are designed. The invention provides a technical process for improving the germination rate of the coixseeds, reducing germination time and improving germination effect. The method is suitable for concentrated non-polluted facility scale cultivation or scattered cultivation, can improve working efficiency and reduce production cost and is suitable to be used by the farmers.

Description

A kind of method that improves germination rate of coixseeds

Technical field

The present invention relates to a kind of method that improves germination rate of coixseeds.

Background technology

Relevant Job's tears cultivation report is more, because Job's tears kind subshell is hard, have only porose being in communication with the outside in carpopodium junction on top, also have kind of clothing to intercept in the shell, influence moisture, air enters, suppressed the germination of Job's tears seed, the germination rate of Job's tears is not high in the production, generally about 60-70%, time is long, generally need 10-14 days, emergence rate and planting percent are lower, have limited the production of Job's tears.In fact, only otherwise damage kind of a benevolence, artificial removal Job's tears kind subshell with plant clothing and can improve the germination rate of Job's tears effectively, be difficult to guarantee that kind of benevolence is excellent but shell, can reduce germination rate on the contrary, effect is bad; Simultaneously, the operation work efficiency of shelling is low, time-consuming, has increased production cost.

Summary of the invention

The present invention with the commonly used fertilizer of peasant household as main chemical agent, utilize the controllable physico-chemical process of peasant household, improve Job's tears germination environment, the growth conditions that design is suitable for germinateing provides a kind of raising germination rate of coixseeds, shorten germinating time, improve the technical process of germination effect, adapt to nuisanceless facility scale cultivation of intensification or scattered cultivation, improve work efficiency, it is low to reduce production costs, and is suitable for peasant household and uses.

Technical program of the present invention lies in: a kind of method that improves germination rate of coixseeds is characterized in that: carry out according to the following steps:

A, material preparatory stage:

1) the Job's tears seed is dried;

2) it is standby as germination matrix to get paddy soils or river sand;

3) the feed product mass ratio is an ammonium sulfate: hydrogen peroxide: water=(2 ~ 10): (1 ~ 5): 10 are configured to treatment fluid A; Get quality of material than being ammonium sulfate: GA ₃: water=(30 ~ 60): 1:(400 ~ 600) be configured to treatment fluid B;

B, processing procedure:

1) germination matrix is irrigated with thimerosal;

2) will be with the germination matrix that thimerosal the irrigates Miao Panzhong that packs into;

3) with the Job's tears seed 38 ℃ drying in oven 4 hours;

4) planting seed after will drying advances in the seedling dish, with treatment fluid A the seedling dish is irrigated, and then covers plastic sheeting for farm use on the seedling dish;

5) with plastic sheeting for farm use the seedling dish is wrapped up after, the seedling dish is put into tank, water temperature is adjusted to 35 ℃, handled 8 hours;

6) plastic sheeting for farm use is opened, the seedling dish is irrigated, wrap plastic sheeting for farm use again, the seedling dish is put into tank, water temperature is adjusted to 25 ℃, handled 16 hours with treatment fluid B;

C, cultivation management stage:

Water temperature in the tank is remained on 25 ℃, adopt natural daylight, guarantee that indoor intensity of illumination is 800-1500lx, keeping relative air humidity is 75 ~ 90%, handles 2 ~ 3 days.

The invention has the advantages that: the Job's tears percentage of seedgermination that adopts said method is up to more than 90%, and the time shortens to 4 ~ 5 days (comprising the processing time); This technology production technology is easy, and material source is extensive, the emergence rate height, and the scattered cultivation of nuisanceless facility cultivation or peasant household is adapted to intensify.

Embodiment

Below in conjunction with embodiment the method for raising germination rate of coixseeds of the present invention is described:

Embodiment 1: the cultivating chamber that illumination and ventilation condition were wet, controlled in, control temperature automatically controlled to have is an example, in cultivating chamber, set up seedling disk frame regularly, its arranging density, trend are advisable with the needs that meet production operation, on seedling disk frame, place tank, described seedling disk frame can adopt the structure more than 5 layers or 5 layers, the specification of seedling dish is generally 28cm * 54cm * 6cm, two kinds in 200 cave/dishes and 72 caves/dish are arranged, difference is: 1 seed of the every bunch planting of the seedling dish of 200 cave/dishes during sowing, 2 seeds of the every bunch planting of the seedling dish in 72 caves, thimerosal is 0.3% carbendazim solution.

Carry out according to the following steps:

A, material preparatory stage:

1) the Job's tears seed is dried;

2) it is standby as germination matrix to get paddy soils or river sand;

3) get ammonium sulfate 250g, hydrogen peroxide 200g, water 1000g is configured to treatment fluid A; Get ammonium sulfate 100g, GA ₃2g, water 1000g is configured to treatment fluid B;

B, processing procedure:

1) germination matrix is irrigated with thimerosal;

3) with the Job's tears seed 38 ℃ drying in oven 4 hours;

C, cultivation management stage:

Embodiment 2: growing seedlings with the simple and easy shading screen canopy of peasant household is example, sets up tank regularly in the net canopy of growing seedlings, and utilizes the environment of two positive eight the moon in natural daylight and the shading screen control net canopy, and thimerosal is 0.3% carbendazim solution, carries out according to the following steps:

A, material preparatory stage:

1) the Job's tears seed is dried;

2) it is standby as germination matrix to get paddy soils or river sand;

3) get ammonium sulfate 300g, hydrogen peroxide 150g, water 1000g is configured to treatment fluid A; Get ammonium sulfate 60g, GA ₃2g, water 1000g is configured to treatment fluid B;

B, processing procedure:

1) germination matrix is irrigated with thimerosal;

3) with the Job's tears seed 38 ℃ drying in oven 4 hours;

5) with plastic sheeting for farm use the seedling dish is wrapped up after, the seedling dish is put into tank, add hot water water temperature be adjusted to 35 ℃, handled 8 hours;

6) plastic sheeting for farm use is opened, the seedling dish is irrigated, wrap plastic sheeting for farm use again, the seedling dish is put into tank, cold water is adjusted to 25 ℃ with water temperature, handled 16 hours with treatment fluid B;

C, cultivation management stage:

Method control tank temperature by artificial adding hot water or cold water remains on 25 ℃, and keeping relative air humidity by water spray or the method that adds forced ventilation is 75 ~ 90%, by the environment of two positive eight the moon in the light transmittance control net canopy of shading screen, handles 2 ~ 3 days.

The Job's tears percentage of seedgermination that adopts said method is up to more than 90%, and the time shortens greatly than prior art, and technology is simple, and material source is wide, both is fit to the nuisanceless enforcement of intensification and cultivates the also scattered cultivation of suitable peasant household, has very strong practicality and generalization.
