Preparation of seed for planting
- 30 Aug 12:45
There are plants with seeds that can sprout without any preparation, but there are also those that need to be prepared. Otherwise they may not release the sprout or germination will occur for a very long time. In any case, if the change is to prepare for theseeding, the similarity will be better and more productive and will not have to regret the work done.
The process of seed preparation for sowing consists of a whole set of works, but they are not always justified. Often, the effect is only one procedure. But it is still better to have an idea of all the existing ways.
Calibration. This procedure can be considered as necessary for the seed. The main task here is to sort the seeds - remove the empty and leave the full. In industrial production is still sorting the sizes, hence the "calibration".Everything is done quite simply. Change should be poured into salt 5% solution. Wait for a while( 10 minutes).During this time, hollow seeds will remain on the surface, and mature will go to the bottom, because they are heavy. Only seeds that have been stored for a long time will also remain above. This happens more often with vegetable crops, while growing flowers only fresh seeds are used.
Wetting. This is one of the common ways to prepare seed for planting. Here, germination occurs in water or with the help of a moistened piece of cloth or napkins. If this method is water, then the liquid should be changed once a day, at least( recommended every 12 hours).If it is a napkin or cloth, then they should always be wet. Soaking gives the opportunity to plant seeds that really sprouted. This fact is very important for seedlings, which are contained in a city apartment. The process of germination needs to be monitored. It should be planted when the sprout has a length of half the width of the seed. But if you miss this point, then there is a chance to damage the germ when landing.
Hormones. A similar way accelerates the seed germination due to hormonal substances that saturate seeds. Different stimulants of growth are used here. Effective results are derived from heteroauxin, corneville and epine. Also in progress is manganese, a solution of baking soda 1%, boric acid, nicotine 0.5%.The folk method, which is quite common, is aloe juice, seeds are soaked in it. Very effective method, similarity 100%.
Stratification. This training is required so that the seeds understand that they will not be given a tropical climate. The essence of the method lies in the so-called deception. For artificial seeds winter conditions are created. You can apply different stratification options, here is one of them:
Capacity needed - the flower pot is just right. It is necessary to prepare a mixture of sand( 1.5 parts), peat( 1 part), and it would be good to add moss to sphagnum( 0.5 parts). This soil close the bottom of the container over the seed, distributing them with a uniform layer, then again the soil and soseveral times. After all, you need to thoroughly polish and put in a package of polyethylene. Next, the pot goes to a cool place, you can even in the fridge. Permissible temperature at stratification 0. .. +5.
Seed germination should be carefully monitored. The mixture should be moistened all the time. Lightweight freezing is allowed, only then it is necessary to defrost only by natural way, no heating devices. The duration of this method can be different, it all depends on the plant. There are flowering cultures, which are enough for one month. To shorten the term of stratification, you can first soak the seeds so that they get tangled.
You can still combine this with calibration. Also there are plants( camellia, feijoa, tea) seeds, which just need to be stratified so that they have good similarity. Buying an entirely unfamiliar plant is worth asking the seller about the seed's preference for the preparation process.
Scarification. A similar method is used for germination of seeds with a hard shell( banana, figurine, cinnamon, etc.).Such a grain is very difficult to overcome the protective shell and sprout on its own. Here, for the sake of simplicity, and scarification is applied. It can be done in two ways: either mechanically or by chemical means. Beginners in floriculture are better off using the chemical method, not risking.
Although it should be noted that the use of chemical solution similarity can give the old seeds. But here you can skip the moment when the family needs to be extracted from the solution. So this method can be used with a large stock of seedlings.
- Chemical way. A 2-3% solution of hydrochloric acid and sulfuric acid is used, seed is placed on it and is there until the shell softens.
- Mechanical method. Here everything is much easier, but the accuracy will still have to be revealed. You need to take a knife, a file, or something like this, and chop the grain surface in several places. You can also use coarse sand or even sandpaper.
Purification. This is an effective way to protect seeds and their stairs from various diseases. This is especially true of the planting material that will be planted directly into the soil. It just needs to be cleaned up. There are seeds that are in sale already drilled. They can be distinguished by color, they have unnatural green, blue, pink and so on. Such seeds no longer need to be treated, but the rest still have to.
One of the easiest ways is to hold seeds in a manganese solution of pink color for half an hour. There are many fungicides and any of them can be applied.
There are other methods of preparing seeds for sowing, and they are not so small. This is snow-removal, scalding or freezing, and others. But the ones that were now considered are perhaps the most basic and easily feasible, and also quite effective.
Probably every gardener, gardener and gardener, who has no small experience behind his shoulders, has a way to prepare the seeds for planting. But beginners are still better to listen to these methods. In the early stages of growing indoor plants or garden flowering, such recommendations will greatly help.
Just do not forget that all the same preparation process may vary depending on the plant. But the basic methods of preparation are calibration, soaking, disinfection, germination, hormone and hardening.
