A lot of people grow their food at home, but onions are always bad. Either they fall and fall back, and they do not grow new leaves, or they grow for a period of time, and they fall in vain. Most people think that they lack water and are rich in fertilizers and pests, but the root causes are particularly simple: the depth of the onions is wrong。
There's an old line saying: deep, shallow, not deep. The survival of the onions, their root roots, their length and whether they are rotten are determined by the depth of planting. Many newcomers feel buried, either too deep or too shallow to fall, working half a day with a very poor final harvest。
Whether it be pellets, courtyard onions, or fall onions, if you remember a certain standard depth, you can leave the rotten yellow leaf, green, white and strong, one inch at a time。
First of all, the core accuracy figures, which are common to all households, are three to four centimetres in optimal depth。
This depth is a gold dimension that has been validated by countless vegetable practices. The layer of the earth protects the roots of the seedlings, so that they are safe from the wind, so that they do not shake their roots, and so that they breathe through the air and grow quickly. The rate of survival can reach almost 100 per cent by completely avoiding the problems of rotting roots, stifling and rigidity。
Let us be clear about the problem of being too deep and too shallow to see what is wrong again。
This is the most common mistake。
Many felt that they were laying deep and firm, and that they were white longer, so they buried most of the ground. Unlike other vegetables, onions require fresh air in their roots, most afraid of soil thickness and lack of ventilation。
The planting depth is more than 5 cm, the earth's layer is so thick that the bottom of the onion seedlings is permanently in a wet and closed environment. After water is poured out, it is only a few days before the stem rots and the roots of the silt. This is reflected in yellow, soft and inverted leaves, slowly aging the whole tree。
In particular, during the high summer and autumn seasons, the hazards are more severe. High temperatures and high humidity, deep-rooted onion seedlings are highly susceptible to rotting roots, and even if they survive, they will be long-lived, stop growing and become weaker。
Let's say it's too shallow。
The planting depth is less than 2 centimetres, the seedling system is not well-established and the earth's surface is not sufficiently gripped. Day-to-day water, wind and rain, onions are easily tilted and shaken. The long-term relaxation of the roots and the inability to absorb water fats firmly lead to the emergence of dry tippings, dead leaves and slow growth。
Small onions, very short white leaves, mostly green leaves, empty mouths and thick fibres, not only vary, but yield is also significantly reduced. A slight shortage of water at a later stage causes the whole tree to die。
In addition to fixed depths, the desire of the onions to stay intact and flourish, there are three key details that are the easiest to ignore by ordinary people。
First, we'll fix the leaves before we plant them, and we'll increase the rate of survival。
You don't plant the seedlings directly with old leaves. Cut dry yellow leaves early, cross the roots of the elders, and keep fresh and green leaves. Old roots are old and poorly absorbed, leaving them in the ground prone to rot and bacterium breeding, indirectly leading to new roots, and simple cutting can significantly increase survival。
Secondly, the onions are planted only with dust, and they are not crushed。
Many people grow their vegetables, which are used to stomping and crushing the soil. Onion seedlings are thin and fragile, press the soil hard, the soil sheet is not airy, the roots are not able to breathe and spread, and the seedlings are easily suffocated。
The right approach is to cover the roots with light and light cover, so that the water is naturally deposited into the solid soil, and the softer and airy soil is most conducive to rooting。
Thirdly, the water must be watered with water。
The planting was completed with an immediate permeation of water, so that the roots and the soil would fit closely and the seedlings would return to the ground quickly. However, pelvis and vegetable fields cannot accumulate on a long-term basis, low-lying water needs to be drained in a timely manner, and long-term damp is the main incentive for bad yellow leaves。
If you want to be strong and productive, remember the technique of planting lots of ground on the ground。
Cultivated at depths of 3 to 4 centimetres of gold during the preceding period, the seedlings grow to more than 20 centimetres and, once they have stabilized, they are prepared lightly every half month. One to two centimeters at a time, don't cover your heart。
It avoids the precipice of a dead and precipice, and in the later stages it produces long white onions, doubles their mouths and yields, which is also the secret to the high productivity of old-school farmers。
Finally, we will take stock of the new hands: three or four centimetres of gold deep, no pressure on the earth, no laxity; the first periods of shallow root-proofing, and the latter periods of onions。
Onions don't use frequent fertilizers, but with a good depth, air and water flow, they can lull and recycle, with fresh onions all year round。
