Growing cucumbers is a long and laborious process. It is important for novice gardeners to remember that the preparation of cucumber seeds for planting in the ground is an important stage, and the correctness of these works is an integral part of obtaining a large and high-quality harvest.
Pre-sorting and processing
Receive strong healthy seedlings of cucumbers is possible only on condition that the cucumber seed undergoes the necessary preventive procedures before planting:
- Selection of strong and high quality seeds;
- Hardening of the planting material;
- Disinfection;
- Etching;
- Pre-germination of seeds for seedlings.
All these operations are performed in a specific sequence, and each of them is a guarantee that the seedlings will grow healthy with a high growth and fruiting potential of cucumbers.
The process of sorting cucumber seeds begins with sifting out weak and diseased seeds. A solution of table salt (1.5 tablespoons per 1 liter of water) will help in this, into which the grains must be dipped. Low-quality and empty seeds will quickly float to the surface, healthy material will remain at the bottom of the container. It is these seeds that must be chosen for growing seedlings.
How to store and warm seeds properly
The second step is drying the seeds. Planting material should be kept in a warm, dry place throughout the entire storage period. Experienced gardeners use small cotton bags to store cucumber seeds, which are hung next to heating systems - stoves or radiators. Using this drying method, remember that the room temperature should not exceed 24-250C. This can lead to drying and steaming of the seeds, which will negatively affect the seedlings in general.
Cold and moisture during storage contribute to the fact that the ovaries produce a large amount of barren flowers, which, of course, will negatively affect the yield of cucumbers.
Seeds for sowing can be warmed up immediately before planting. To do this, they are quenched using a thermostat - at a temperature of 550C - 3-3.5 hours, at 600C - 2 hours. Such heating of the planting material affects the growth rate of seedlings and the stability when transplanting seedlings into open ground.
What is the etching of planting material for?
After the cucumber seeds are sorted, you need pickle their. This stage in the preparation of planting material is preventive, and prevents the development of viral and fungal diseases that are characteristic of growing seedlings in greenhouse conditions.
Disinfection is carried out by immersing cucumber seeds in a warm one percent manganese solution (10 g of manganese for 10 liters of water). If manganese is not available in pharmacies, use a solution with streptomycin. In both cases, the planting material is kept in the solution for at least a day. After that, the cucumber grains are washed with warm running water.
Another way to disinfect seeds is to use crushed or grated garlic. A large clove of garlic is chopped with a knife or grated and dissolved in a glass of warm boiled water.After the solution has cooled, the volume of the liquid is brought to 1 liter, and the seeds in gauze or a cotton bag are lowered into the container. The planting material is kept in a garlic solution for 30-40 minutes.
In shops and agricultural markets, you can see preparations specially prepared for pickling. The most popular and well-proven ones are TMTD and NIUIF-2.
Industrial pickling agents are highly poisons. When working with them, be sure to use protective equipment such as masks or gauze bandages, gloves, glasses.
For 1 kg of planting material, only 3-4 grams of TMTD or NIUIF-2 are used. The sorted cucumber grains are laid out in a three-liter bottle, and a disinfectant is poured there. The bottle closes tightly and shakes well. After the procedure, the seeds are rinsed in warm running water.
How to quickly and correctly germinate a seed
Every gardener strives to ensure that the harvest begins to ripen as quickly as possible. In order to increase and accelerate the germination of a change to seedlings before planting, it is necessary to germinate, using growth stimulants in the form of chemical and biogenic fertilizers.
You can quickly germinate a seed by preparing one of the solutions:
- 2 grams of zinc sulfate per 1 liter of water;
- 5 grams of baking soda per 1 liter of water;
- 10mg boric acid per 1 liter of water.
The hardening of cucumber seeds for seedlings is carried out by soaking the planting material for at least 20 hours. The solution should be cool - 18-200C. It is better to carry out the procedure in the evening, and the next day to dry the grains on a cotton napkin or rags.
And the last stage of the procedure - dry cucumber seeds are spread on a flat surface and covered with a small layer of fine sawdust, previously scalded with boiling water. Under such a fur coat, the seedlings are kept for 48 hours.
Of the natural biostimulants, the juice obtained from the stem and leaf of aloe is considered the best. Known for its antibacterial properties, this home flower helps the seed to swell and open up.
Cut the juice from 2-3 large sheets of aloe lengthwise and place in a plastic bag. Determine the leaves in the refrigerator for 10-14 days and keep there at a temperature of no more than 70C. The stems or leaves matured in this way are twisted in a meat grinder, squeeze juice from the resulting gruel, into which sorted cucumber seeds are placed for 5-6 hours.
Both methods of stimulation are carried out just before planting. To get high-quality and strong seedlings, it is enough to harden after each procedure - for 2-3 days, the planting material is sent to the refrigerator. Thus, the grains adapt to possible low air and soil temperatures.
How and for what hardening is carried out
Experienced gardeners harden only those cucumber seeds that are planted directly in the open ground. By itself, such a stage in the preparation of planting material implies keeping it for a short period of time in conditions of low temperatures. Thus, it is possible to artificially increase the protective functions and resistance to low temperatures in many varieties or hybrids.
In addition, a set of procedures - calibration, drying and hardening of seeds for seedlings - increases the concentration of sugar. This indicator, in turn, affects growth inhibitors. All preparatory processes affect both the growing season of fruits and the periods of ripening of the plant.
Moreover, such procedures are not carried out when the grain has entered the phase of active germination.
Conclusion
All stages and procedures for preparing cucumber seeds for planting justify themselves since the middle of the last century, when hardening, as a method of improving germination, was first used in the agricultural sector.When growing cucumbers, remember that hardening the seeds and preparing them for germination is already half the success in getting a quick and tasty harvest.
