Preparatory vegetables are available either in the spring or the summer or the autumn or the winter, and although they are more abundant, they take some time to grow. As the hot pot is popular, lettuce is also a necessary vegetable when people eat the hot pot. Today's writer wants to talk to you about how he can grow a healthy seedling, whether it be a vegetable grown in a large shed or an open-air vegetable, which is the first step in ensuring a harvest。
1. Preparation of nursery beds
The temperature of seedlings needs to be secured: safe open-air seeding can take place when the average temperature reaches 10 degrees, but a measure of protection is required below 10 degrees. In summer, the temperature will be contained to bring it down, and the rain will be contained in a shade. The nursery bed demands that the whole nursery bed be nuanced and flat and, above all, fertile. Farmer fattening of 10 to 20 kg per square metre of seedbed can be applied, and phosphorous fertilization of about 0. 025 kg per square metre can be applied appropriately. Spreading the fertilizer, wiping the whole soil and flatting the surface. Care must be taken to fill the ground with water before planting, and when the water penetrates, a sifted layer of ground is laid on the surface, then the seeds can be spilled. 25 grams of seeds can basically plant an acre of field。
2. Treatment of seedlings
In order to soak the seeds, a filtered culturer or sandbag is to be found, in the absence of which it can be replaced by a gauze, which can be used one night in a refrigerator at temperatures of 4-6 degrees. In order for the treated seed to be distributed more evenly into the seedbed, it can be blended into a small amount of fine-tidal soil, with full parity. The seeding is followed by a cover of 0. 5 cm. If the upper membrane is to be covered after planting in the winter, the temperature guarantees are increased. The planting in the summer is to bring up the sunnet to cool the seedbeds and ensure that the seedlings are out of the ground。
3. Management of the seed age
The first concern during the seeding period is the temperature, which is kept between 16 and 20 degrees during the day and about 10 degrees at night. The seedlings are distributed when they reach two or three leaves. Here, i offer you two ways of distributing seedlings, along with nursery beds. Each has its own advantages, and nutrition can better guarantee the roots of the seedlings of raw vegetables, which can be quickly slowd down when established. The use of sapling beds is preceded by watering, but saplings should be subject to the same precision as seedlings. The seedlings from seedlings are planted from 6 to 8 cm range. When the seedlings are completed, the water must be watered immediately, and something must be covered on the seedlings in order to sow. The seedlings are then controlled, so that they can take root and grow. Because the temperature varies greatly from time to time, the seeding period is different. In the period from april to september, it took about 25 to 30 days to start. It takes 30 to 40 days for a nursery to take place between january and march。
4. The seedlings are planted
The most important focus is on the roots of seedlings, which must ensure the integrity of the roots and make it possible to significantly reduce the duration of the seedlings, so as to reduce the time taken to grow raw vegetables. The timing of planting is when the seedlings have five or six leaves. Flexible planting methods vary according to weather and season. The three seasons of spring, summer and autumn were used for water irrigation after the field was planted to dig and plant. In winter and spring, protected ground cultivation can take water seedlings, meaning that a ditch can be established within the rim by line distance, and seedlings can then be set at the range of the plant, and then stabilized with shallow soil. It was then filled with water and buried again. This will occasionally avoid the adverse effects of slow seedlings due to the low temperatures on the ground caused by full-scale irrigation。
4. Special attention
(1) cultivation in a ditch instead of on a crotch
Seeds require a large amount of moisture during gestation and seedlings, and whether the soil in the seedbed is wet will affect seed gestation and the slowness and subsequent growth of seedlings. For the current weather, this time is dry and prone to wind. This is contrary to the nature of the raw vegetables themselves that require water to grow, so it is easier to grow and manage a seedling in a ditch than on a crotch。
(2) bottom soils of seedbeds and covered soils shall be wetted with water
Pre-planting is preceded by more advanced wet-smoking beds, which can be fully sowed after infiltration. This ensures that the nursery bed is wet and that the soil is not sticky, making the entire bed more evenly wet. The drying of part of the soil as a result of water spills can be avoided, resulting in poor seeding and the wetting of part of the soil。
(3) covering things before seeding
We've already talked about the fact that lettuce sprouts in the seeding seasons require strict control temperatures. Temperatures above constant temperatures of 25 degrees are affected by gerontization, which prevents the growth of poor seed activity. But it can still take place at lower temperatures, for example, at about 5 degrees to ensure that raw vegetables do so, except for the longer term. So in order to protect the temperature of the seed season, we have to choose the cover, and the pen recommends straw, which is both wet and warm. In some areas, the temperature varies between day and night, at around 10 degrees during the daytime at 30 degrees, and the seedbeds covered with straw are more conducive to the seedlings and seedlings. It usually takes three or four days for the seedlings to be planted, but to remove the covered straw in time for it to be removed when the seedlings are a little dirty。
Iv. Powder for the planting of small animals
There are small animals who like to eat young vegetable leaves, especially ants. We have to protect the ants from the lettuce. These little animals are most afraid of the irritating things such as chili powder, garlic paste, mint leaves, sulfur soap, soap, which can be spread around their seedbeds (the latter two recommendations are diluted with water) to protect ants from the seeds of raw vegetables; of course, you can buy something more specialized to prevent, and you can guard against many small creatures other than ants。
And that's what i'm talking about today, when we've got a little longer seeding period, so there's a lot of little detail in this period, like temperature, little pests and so on. The other point is that when we plant, we make sure that the roots of the seedlings are complete, so that the time of the seedlings can be considerably reduced. Readers need anything else. Leave a message in the area. I'll see you next time。
