Abstract

The invention discloses a seedling growing method for cucumber seeds with a high germination rate. The method comprises the following steps: preparing cucumber seeds; soaking and pre-treating the cucumber seeds; performing pesticide treatment on the cucumber seeds; sterilizing the cucumber seeds; performing accelerating germination on the cucumber seeds; and sowing the cucumber seeds. Compared with the existing cucumber seedling growing technology, the seedling growing method disclosed by the invention has the advantages that the seed germination rate is 95.7-97.6%, the seedling transplanting survival rate is 90.4-95.8%, the cultivated seedlings have strong growth vigor, and developed root system, and are high in disease resistance and high in transplanting adaptability, and the incidence rate of downy mildew, black spot and powdery mildew in the cultivation period is obviously reduced. Moreover, the cold resistance of cucumber can be improved, the flowering rate and setting percentage of the cucumber are improved, the cultivated cucumber is good in taste and has the sugar content of over 6.5%, the yield is improved by 8% compared with that of general planting, the content of vitamin C in the cucumber fruits is obviously increased, and the economic benefits are good.

Description

A kind of method for culturing seedlings of cucumber seeds high germination rate

Technical field

The present invention relates to field of planting, particularly relate to the method for culturing seedlings of a kind of cucumber seeds high germination rate.

Background technology

Cucumber original name cucumber, meat is tender and crisp, and juice multi-flavor is sweet, promotes the production of body fluid and quenches one's thirst, and has special fragrance.Cucumber does not contain only the multivitamins such as crude fibre, vitamin B1, riboflavin, nicotinic acid, vitamin C, also can promote the production of body fluid to quench thirst, relieving restlessness relieving summer-heat, swelling diuretic, controls abscess of throat, and four limbs edema, hot dysentery such as are had blood in stool at the effect.Therefore one of requisite vegetables in Modern Family's life are become.The Seed Germination in Cucumber rate of existing planting technology plantation is low, it is low to plant shoot survival percent, and setting percentage is low, thus can improve production cost.

Summary of the invention

In order to overcome above-mentioned deficiency, the invention provides the method for culturing seedlings of a kind of cucumber seeds high germination rate.

The present invention is achieved through the following technical solutions:

A kind of method for culturing seedlings of cucumber seeds high germination rate, including:

1) preparation of cucumber seeds: select natural maturity, healthy and strong cucumber seeds for nursery；

2) dipping pretreatment of cucumber seeds: at cucumber seeds is put into 30-35 DEG C mass percent be 3.5% sodium bicarbonate solution in soak 1 hour, it is possible to break the dormancy of seed to a certain extent, promote the permeability of seed coat, further take out, drain；

3) chemicals treatment of cucumber seeds: utilize Fusarium Wilt of Sweet infused cucumber seed 4-6 hour, described medicament is by mass percentage by 2% sodium chloride, 0.1% paddy skin myron liquid, 1.2% acetic acid, 2.5% sucrose, remaining forms for clear water, each interaction between component, seed dormancy can be broken further, improve the permeability of seed coat, additionally it is possible to strengthen cellular respiration, promote cell division and differentiation；

4) cucumber seeds sterilization: above-mentioned cucumber seeds uses potassium permanganate, the 8% sodium chloride mixed solution of 0.1% carry out immersion treatment by mass percentage, the process time is 10 minutes, it is possible to alleviates and controls common some virosis, early late blight and the disease of bacterium one class；

5) cucumber seeds vernalization: cucumber seeds is placed in culture dish, vernalization 20 hours under the environment temperature of 28-35 DEG C, 15th hour when, the radiation treatment that seed employing is changed 2 hours, radiation unit's areal intensity scope of described change is 0-30 μ W/cm, when radiation unit's areal intensity is 0, start every 10s to be incremented by once, incremental change is 1 μ W/cm every time, until radiation unit's areal intensity increases to 30 μ W/cm, and then, start every 5s and successively decrease once, decrement is 15 μ W/cm every time, until radiation unit's areal intensity is reduced to 0, follow-up circulate successively；Radiation unit's intensity use the slow mode rising fast fall be changed, the level of seed cell endogenous hormones can be promoted, promote to sprout, improve germination percentage, the cucumber mouthfeel more preferable, sugary more than 6.5% cultivated, yield is than general plantation lifting 8%, 17th hour when, the magnetic field that seed uses change processes, showing money or valuables one carries unintentionally to more than 95% cucumber seeds；The magnetic field of described change, the scope of change of magnetic field strength is at 0-60mT, when magnetic field intensity is 0, start by the speed increase of 1mT/10s, until magnetic field intensity reaches 60mT, and then, by the decrease of speed of 15mT/10s, until magnetic field intensity is to 0, follow-up circulate successively；Process in the magnetic field beginning with change for 15 hours of vernalization, the activity of various enzymes in enzymatic reaction can be promoted, strengthen the breathing of cell further, accelerate seed nutriment is absorbed, and magnetic field intensity use the slow mode rising fast fall carry out change of magnetic field strength, early stage can promote the growth of cucumber embryo, and can improve flowering rate and the setting percentage of later stage cucumber；

6) cucumber seeds sowing: the cucumber seeds showed money or valuables one carries unintentionally is sowed.

The invention has the beneficial effects as follows: compared with existing cucumber seedling-raising technology, the present invention has extremely significantly advantage, technique scheme is used to carry out cucumber seeds nursery, percentage of seedgermination is at 95.7%-97.6%, seedling replanting survival rate is at 90.4%-95.8%, the seedling cultivated, growth potential is strong, well developed root system, disease resistance is strong, nurturing period downy mildew, black spot, the powdery mildew incidence of disease substantially reduces, strong adaptability after transplanting, and the cold tolerance of cucumber can also be improved, improve cucumber flowering rate and setting percentage, the cucumber mouthfeel cultivated is more preferable, sugary more than 6.5%, yield is than general plantation lifting 8%, and, the ascorbic content of cucumber fruits substantially increases, good in economic efficiency.

Detailed description of the invention

Using technique scheme to carry out cucumber seeds nursery, percentage of seedgermination is at 95.7%-97.6%, and seedling replanting survival rate is at 90.4%-95.8%.
