What are the soil requirements when growing lettuce?

The cultivation of lettuce does not have special requirements for the soil. Generally speaking, barren mountains, wastelands, fields, and woodlands can be used to grow lettuce, as long as it is not those soils that are too acidic or too alkaline. There are also zongzi in my vegetable garden, and this lettuce is especially good to choose to grow lettuce in winter, which can be used to make this lettuce rice and can also be used to make hot pot.

If I had to ask for something, thenpHIt's best to stay around. An pH is more suitable for the growth of lettuce, after all, lettuce likes slightly acidic soil. It doesn't matter if the pH is not enough, just like a person has the best one health standard.

But sometimes we can't reach it and it doesn't affect our health, nor does it affect our normal growth, in fact, the same is true for growing vegetables. Although it requires a standard degree, as long as it is within the approximate range, it will not be much of a problem. <>

Lettuce planting soil must be kept moist, and there is a certain amount of humidity to grow better. Lettuce still prefers a humid environment, after all, lettuce needs a lot of water, if the water is insufficient, since it is easy to yellow and easy to dry up, it is not conducive to the growth of lettuce. Someone has done corresponding research, in the case of lack of water, lettuce does not grow well, is easy to yellow, and the taste is also very poor, so this point must be noted.

The soil for growing lettuce must be goodSun exposureIt will grow better when it is exposed to sufficient sunlight, and lettuce also needs a certain amount of fertilizer, because lettuce tends to grow faster in the middle and late stages, so it needs a lot of nutrients. We need to give supplements to this potash, phosphate, and nitrogen fertilizers, if the potassium fertilizer is insufficient, it will affect the photosynthesis of lettuce.

It also affects its growth and leaf hypertrophy. <>

Finally, lettuce planting soil must have a certain degree of air permeability, and we must turn the soil when planting. If the ventilation is good, the lettuce will grow well, because the ventilation is not good, and if the land is not ploughed, it is difficult for the root system of lettuce to extend downward.

The root system of lettuce in the soil is relatively shallow, and the requirements for planting soil are: soft, breathable, and moisturizing, do not choose the sticky and impermeable soil, do not choose the rusty and dry and water-deficient soil, and do not choose the land soil that is not exposed to the sun.

It is required to choose a slightly acidic soil with fertile, rich organic matter, strong water and fertility retention, good air permeability, and convenient drainage and irrigation.

When growing vegetables, the soil requirements should be suitable for temperature, moisture and humidity, and the soil should be kept soft.

Every farmer wants to grow vegetables in a way that is low investment and high returns, so the soil in which the vegetables are grown is important.

Different vegetables have different soil needs, and they all need fertile soil to grow well. Then, vegetables should also have good drainage, because the root system of vegetables is not particularly developed, and if it is in water for a long time, it can easily rot. Most vegetables prefer to grow in slightly acidic or neutral soils, and alkaline soils are generally not suitable for them to grow.

Except for some fast-growing vegetables, most of the vegetables have a long growing period and require a lot of nutrients during the continuous growth period, so we will fertilize. However, although the fertilization efficiency is fast, it will have an adverse impact on the soil environment, reduce the content of soil humus, destroy the structure of soil aggregates, and reduce the content of organic matter in fertile soil.

Then it is neededOrganic fertilizerContinuously improve the soil environment. Compared with chemical fertilizers, there are many kinds of common organic fertilizers, such as animal manure, bean dregs, aromatic oil residues, straw, wood ash, etc., but the best fertilizer to improve the soil environment is sheep manure or cow manure.

Soils are generally divided into two types, one is:Acidic soils, one isAlkaline soils。In general, different vegetables also have different requirements for the soil. Most vegetables prefer slightly acidic soils with a pH between to.

If vegetables that prefer acidic soils are grown in alkaline soils, they often lead to the occurrence of pests and diseases. Vice versa.

SoSoil qualityThe choice is very important. On the one hand, it should be suitable for cultivation and ploughing, and on the other hand, it should ensure that the soil is loose, breathable, well-drained and nutritious. High-quality soil substrate can achieve twice the result with half the effort in vegetable planting.

And whether it is on the balcony or in vegetable planting, the growth interval between vegetables and vegetables should be kept relatively open, and the growth space of vegetables should not be excessively squeezed, so that the development ability of vegetables will decline and affect the quality of vegetables.

If you want to grow good vegetables, you definitely need a good foundation, so we must pay attention to the problem of soil when growing vegetables!

Fertile soil is needed, and it is also necessary to maintain the appropriate acidity and alkali synthesis of the soil, it is best to choose sandy soil, which needs timely watering and fertilization, strengthens the management of water and fertilizer, and timely loosens the soil to ensure the permeability of the soil.

The requirements for the soil are that it should be planted in alkaline soil, there should be no pest problems in the soil, the soil moisture should be relatively good, and the soil should be very fertile. It can be chosen according to the state of the soil, the fertility of the soil, the nutrients of the soil, so that you can find the right soil for planting.

There are particularly high requirements, the drainage of the soil is good, particularly good, the soil should be fertile, there is nutritional value, different soil should be selected according to different vegetables, and then water and fertilizer management should be strengthened, drainage work should be done, and the soil should be loosened in time.

Different vegetables have different requirements for the soil, so in the process of agricultural planting, we should choose suitable varieties for planting according to local conditions.

Lettuce is sown in spring and autumn.

Lettuce seedlings should be selected with good water retention, fertilizer retention, and fertile sandy loam. Bed soil preparation: 10 square meters of seedbed with 10 kg of rotted organic fertilizer, 10 kg of ammonium sulfate, kg of superphosphate, kg of potassium sulfate, fully mixed and evenly paved with fine rake, watered with foot water, sown after water infiltration.

In order to make the sowing even, a small amount of fine sand can be mixed into the seeds during sowing, covered with centimeter-thick tidal soil after sowing, and covered with plastic film to moisturize. The sowing rate per mu is 30-50 grams. When the seedlings begin to be unearthed, the furrow mulch should be uncovered in time to prevent growth.

There are three ways to grow lettuce at home:

1. In fact, lettuce can be planted all year round, as long as the temperature is below 20 degrees, it can be sown at any time, and if the temperature is high, you want to plant lettuce, you can also choose some heat-resistant lettuce varieties to plant, the general lettuce is very suitable for sowing in autumn, so that it will continue to grow in winter.

There are many types of lettuce, some are smaller, some can form balls, some have larger leaves, some have a better taste, and some purple-leaved lettuce, and the planting methods are similar.

2. As for the choice of lettuce planting tools, as long as it is a container that can be loaded into the soil, it can be planted, pay attention to flower pots or other containers, foam boxes, empty oil drums, and there must be drainage holes, otherwise the growth is not good, and it is easy to yellow leaves, because the potting soil is easy to accumulate water.

It is recommended to use some plastic long pots, so that you can plant a lot of seedlings, and it is easy to place, plant a few pots on the balcony, more neat, clean and beautiful. You can use ordinary garden soil for potting soil, and if you don't want to buy soil back, you can also mix soil yourself.

It is to add some fertile humus to the soil, or add some well-rotted organic fertilizer, chicken manure, sheep manure, etc., to increase the fertility of the soil, and continue to provide nutrients for lettuce seedlings.

3. Before sowing, make the potting soil looser, softer, pinch the potting soil by hand, it will not form a clump, if the seeds are sprinkled unevenly, you can mix them with the sand, sprinkle them in the pot, sow them for the first time, try to sprinkle a little less seeds, and be even.

Then water thoroughly and put it on the balcony in a well-lit, ventilated place with a temperature of about 20 degrees, and the germination rate will be very fast. After germination, when three leaves generally grow, if the seedlings are too many and too dense, you can pull out some, or wait until the seedlings grow up again, you can transplant some seedlings.

The transplanted lettuce seedlings will grow better, and the transplanted and untransplanted seedlings are completely different, and the transplanted lettuce will grow particularly lush and the leaves will be larger. In short, the spacing between seedlings should not be too small, otherwise they will not get enough nutrients and sunlight, and the growth will be poor.

After germination and seedling, it is necessary to increase the light, after growing up, it is necessary to supplement some fertilizer, which must be fertilized, you can pour some cake fertilizer water, or sheep manure soaked in water, watered in the pot soil, there is really no organic fertilizer, you can give some compound fertilizer or chemical fertilizer, no fertilizer must not grow lush, and at the same time watering should be timely, the potting soil is too dry, and the lettuce leaves are not watery enough.

Only sufficient fertilizer and water and light can make the leaves more delicious and taste better. Lettuce is very easy to grow, you will know if you have planted it once, and the balcony has become a world of lettuce, and it has become a beautiful and vibrant little vegetable garden, and you can eat the freshest lettuce.

Lettuce is a kind of fruit and vegetable that everyone loves. It contains vitamin E and carotene. It also improves the digestion of a wide variety of body fats and proteins. So, how should lettuce be grown?

Lettuce loves the cold climate, so it is generally planted in autumn and spring. Spring planting is generally gradual, obtained from February to April, obtained from May to June, and autumn planting can be done at the end of August. September-October gradually.

It can be obtained, because different varieties of lettuce have different characteristics. When choosing a sowing time, you should first grasp the instruction manual of the lettuce seeds you have purchased, and then start sowing on top of the sowing time. In summer and autumn, metastatic lung cancer leaf lettuce (such as whipped cream lettuce) is preferred.

Color-leaved lettuce), which is more resistant to high temperatures, and should be sown lettuce (also known as Xiwo bamboo shoots) in autumn and winter, and is not resistant to high temperatures.

1.The seedbed is prepared in advance. Loosen the seedbed, level the soil layer, apply agricultural fertilizer, and ensure that the seedbed soil is finely crushed. Leveling. Rich in nutrients.

2.Soak the seeds to speed up germination. Place the lettuce seeds in a wet sand cloth belt and soak the seeds in cold water. The soaking time is about 3 to 4 hours, and the temperature is generally 20 slow burning. After the seeds are soaked, gently rub and clean, control the moisture, seal the bag and promote teeth.

3.Sow seedlings. Before sowing, the seedbed should be watered and moderately sprayed with dimethoate pesticide aqueous solution can reasonably avoid the occurrence of diseases.

Then sow according to the sowing specification, that is, sow 1 gram of lettuce seeds per square meter of seedbed. The soil is then covered tightly to create an excellent natural environment for the lettuce seeds to grow. When the seedlings are excavated, this covering layer must be eliminated immediately, and the temperature (15-20°C) must be strictly controlled after budding, and hydration and moisturizing are also indispensable.

4.Transplanting management methods. When the seedlings are less than 1 month old, lettuce seedlings can be planted. When transplanting, the seedlings should be stabilized and watered in the furrow to give the necessary water.

5.Cultivation and elimination technology. The cultivation technique is watering. Topdressing. In the daily work of hoeing, it is generally watered every 5-7 days. Special attention must be paid to the topdressing with nitrogen. Compound fertilizers such as phosphorus are appropriate, and top dressing is not required in the early stage.

6.Pest control. Lettuce diseases specifically include lettuce downy mildew.

Lettuce downy mildew. whiteflies, etc., so in the whole process of prevention, it is necessary to refer to the actual situation of pests and diseases to carry out solutions. For example, lettuce downy mildew can be liquidated with 50% benzyl wettable powder 1000 times.

40% Hongfu emulsifiable concentrate 7000 times liquid spraying prevention.

When planting lettuce, you need to choose the right time, lettuce likes to grow in a cold environment, so it is recommended to plant it around April every year. Most of the northern regions are mainly cultivated in spring, and the planting time in South China should be selected from September to December, and if it is planted in a greenhouse, it can be planted all year round.

Lettuce seeds are neither cold nor heat tolerant, and the seeds can germinate in an environment of about 4 in a local environment of about 4 compared to low temperatures, and almost do not germinate above 30. If the temperature is consistently higher than 25, the growth of lettuce will deteriorate, and the leaves will be coarse and old, affecting the taste.

Lettuce is suitable for growing in loose, fertile and well-drained soil. When planting, humus, garden soil and sand and gravel can be mixed into nutrient soil for planting. In addition, it is necessary to add an appropriate amount of basal fertilizer to the soil to increase the nutrients of the soil, so that the lettuce is more vigorous and robust during the growth process.

During the planting of lettuce, watering every 5-7 days, try to choose to water in the morning or evening, high temperature watering is not conducive to the growth of the root system. When fertilizing, it is necessary to pay attention to the use of well-rotted fertilizer, otherwise there will be a risk of root burning, usually 15-20 days to apply a rotten farm fertilizer.

In the planting we have to choose their own varieties to be planted, under normal circumstances, folded leaf lettuce and erect lettuce in the northern region is suitable for planting in spring and autumn, the climate and environment of the southern region is suitable for the growth of lettuce throughout the year, so lettuce for the southern region planting, the quality of variety selection is the most important requirement, if we choose a variety is not good, then you then how you plant the yield will not be very high. According to your local climatic conditions, cultivation season, cultivation methods and market demand, choose the right varieties

When sowing seeds, the density of the seeds should be higher; The seeds of lettuce can be planted in the way of hole sowing, and 3 to 4 lettuce seeds per hole can be planted when sowing, and the lettuce with balls and hearts can be planted when the lettuce has three leaves. Therefore, the lettuce can be germinated, the seeds can be soaked in water for 6-7 hours, and after being fished out, they can be wrapped in a cloth and placed in the fresh-keeping room of the refrigerator, and they can be sown when more than half of the seeds are exposed. Lettuce transplanting period needs 3-5 leaves is better.

The leaves of lettuce are tender and crisp, and are rich in nutrients such as protein, fat, sugar, vitamins and trace elements. Lettuce leaves contain lettuce, which has good health effects on promoting blood circulation, analgesia, diuresis, and sleep. Lettuce can be grown all year roundWrinkled leaf lettuce:

Wrinkled leaf lettuce is not a ball, basal leaves, the leaves are long oval, the petioles are long, the leaf margins are wavy with notches or deep fissures, the leaf surface is shrunken, and the clusters of leaves are like large flowers, among which the better performance is purple leaf lettuce, safflower leaf lettuce, etc.

Long-leaf lettuce Long-leaf lettuce, also known as erect lettuce, grows upright or semi-erect, the leaves are oblong-obovate, the leaf margins are wavy or jagged, the leaf surface is slightly wrinkled, and it does not form balls or can form loose cylindrical leaf-strengthening balls in the cold season. The effect of preventing vascular diseases is favored by consumers because of its rich nutritional value. Therefore, growers can appropriately increase the planting area of lettuce, and at the same time further do a good job in the planting and cultivation management of lettuce, meet market demand, and continuously improve the economic benefits of lettuce lettuce planting.
