Abstract

The invention discloses a method for increasing the germination rate of pumpkin seeds. The method includes the steps that the pumpkin seeds are placed inside an acetic acid solution to be soaked; the pumpkin seeds are placed into clear water to be soaked for 2-4 hours; the pumpkin seeds are sequentially placed into gibberellin and heteroauxin mixed solutions of different concentrations to be soaked; the pumpkin seeds are placed at 26-28 DEG C to accelerate germination and splashed with clear water two times each day. The pumpkin seeds are soaked inside the acetic acid solution to enable seed coats to be softened, which facilitates germination; the gibberellion and heteroauxin mixed solutions of different concentrations are adopted for soaking to divide and differentiate seed cells and promote growth of seed embryos, seed germination time is shortened, good bases are laid for breaking through the seed coats for the embryos, and the germination rate of the seeds is greatly increased. By the adoption of the method, the germination rate reaches 98.6%, the growth period of pumpkins can be obviously shortened, and the method can greatly improve the activity of seedlings after the treated seeds germinate.

Description

A kind of method promoting Pumpkin Seed germination rate

Technical field

The present invention relates to field of planting, particularly relate to a kind of method promoting Pumpkin Seed germination rate.

Background technology

Pumpkin, Shandong District is called hangs melon, and the Northeast is called pumpkin.Edible, has crocus and cyan two kinds, and profile is oblate or irregular gourd shape, and the crisp meat of immature fruit skin is fine and close, and can garnish food, cook filling, sweet of ripening fruits, can cook gruel.Existing pumpkin planting technology, on the low side in Pumpkin Seed germination rate, cause many seeds to waste.

Summary of the invention

The object of this invention is to provide a kind of method promoting Pumpkin Seed germination rate, promote the germination rate of Pumpkin Seed.

The present invention is achieved through the following technical solutions:

A kind of method promoting Pumpkin Seed germination rate:

1) pull out after 1.5% acetic acid solution Pumpkin Seed being put into 25-30 DEG C soaks 15-30 minute;

2) Pumpkin Seed is put into 20-25 DEG C of clear water and soak 2-4 hour;

3) Pumpkin Seed being put into respectively successively concentration is that the mixed solution of 100mg/L gibberellin and the 50mg/L heteroauxin mixed solution of 1:1,150mg/L gibberellin and the 75mg/L heteroauxin mixed solution of 1:1,200mg/L gibberellin and the 100mg/L heteroauxin mixed solution of 1:1,250mg/L gibberellin and the 125mg/L heteroauxin mixed solution of 1:1,300mg/L gibberellin and 150mg/L heteroauxin 1:1 by volume by volume by volume by volume by volume soaks, and soaks 2 hours at every turn;

4) vernalization at Pumpkin Seed being put into 26-28 DEG C, every day splashes 2 times with clear water, every minor tick 3-5 hour.

The invention has the beneficial effects as follows: by the method promoting Pumpkin Seed germination rate a kind of disclosed in the present invention, seed hull can be made weak by adopting in 25-30 DEG C of acetic acid solution to soak, be easy to brokenly bud, for subsequent treatment makes good place mat, the gibberellin of variable concentrations and heteroauxin solution is adopted to soak the growth that seed cell Differentiation can be made to promote seed embryo respectively, shorten the time of seed sprouting, break through seed coat for embryo to lay a good foundation, the germination rate of very big raising seed, the inventive method germination rate is adopted to reach 98.6%, and survival rate high after germinateing can be ensured, obviously can shorten the growth cycle of pumpkin, the inventive method can greatly improve the vigor of the seedling after the seed sprouting of process.

Embodiment

A kind of method promoting Pumpkin Seed germination rate:

1) pull out after 1.5% acetic acid solution Pumpkin Seed being put into 25-30 DEG C soaks 15-30 minute;

2) Pumpkin Seed is put into 20-25 DEG C of clear water and soak 2-4 hour;

3) Pumpkin Seed being put into respectively successively concentration is that the mixed solution of 100mg/L gibberellin and the 50mg/L heteroauxin mixed solution of 1:1,150mg/L gibberellin and the 75mg/L heteroauxin mixed solution of 1:1,200mg/L gibberellin and the 100mg/L heteroauxin mixed solution of 1:1,250mg/L gibberellin and the 125mg/L heteroauxin mixed solution of 1:1,300mg/L gibberellin and 150mg/L heteroauxin 1:1 by volume by volume by volume by volume by volume soaks, and soaks 2 hours at every turn;

4) vernalization at Pumpkin Seed being put into 26-28 DEG C, every day splashes 2 times with clear water, every minor tick 3-5 hour.

Choose the ground plantation pumpkin of identical size, adopt different process according to the inventive method step, statistical correlation data.

Table 1

In table 1,1:1 is used in combination by volume for contrast 1 use 100mg/L gibberellin and 50mg/L heteroauxin solution; Contrast 2 uses 200mg/L gibberellin and 100mg/L heteroauxin mixed solution, and 1:1 is used in combination by volume; Contrast 3 uses 300mg/L gibberellin and 150mg/L heteroauxin mixed solution, and 1:1 is used in combination by volume; Each group of experiment condition is identical, in contrast groups, first uses clear water to soak 8h, then uses the solution-treated 2h prepared in contrast groups.

Can find out by the pumpkin germination rate of the inventive method process lower than what operate not in accordance with the inventive method by table 1, immersion is low to the raising effect of percentage of seedgermination than not allowing the classification of concentration Gibberellins solution to adopt the Gibberellins solution of fixed concentration to soak effect, and the inventive method significantly shortens the time of seed sprouting, processing method of the present invention can greatly improve the vigor of seedling.
