What are the key points of timely planting and seedling planting of carrots? What should I pay atten

Growing carrots now is not more profitable than before. If you want to increase your income, you need to expand the scale and plant large-scale seedlings to reduce the cost of rising profits. The management of carrot seedlings in large-scale planting is very important, as long as you can gain a firm foothold in seedling raising, you can reduce the pressure of subsequent planting.

At the same time, there are many points to pay attention to in the management of stunts. The period when a carrot germinates and has five leaves is called the budding stage, during which the carrot seedlings photosynthesize.

The ability is relatively weak, the roots are not fully recovered, the absorption capacity is not strong, and the growth rate is relatively slow. At this stage, the resistance to seedlings is low, susceptible to the influence of weeds, and a leaf grows in 5 days, if the management is not standardized, it will cause the loss of seedlings, and the later eating effect will also be affected.

In order to ensure the healthy development of carrot seedlings, we should choose fields with sufficient nutrients for planting. The field should have a certain amount of fertilizer, be moist enough, and have good drainage measures, so that the seedlings can be raised normally. In order to increase the planting amount of carrots, it is necessary to ensure that the number of seedlings after seedling raising is sufficient, which is also the basis for ensuring the yield.

Therefore, after planting the seedlings, it is necessary to investigate the seedlings in time. Because carrot seedlings are prone to death, the emergence rate is relatively low, sometimes less than 50%. Therefore, it is necessary to replenish seedlings and improved varieties in time to ensure the perfection of seedlings.

Carrot seeds need 5 degrees for germination, the temperature suitable for germination is 22 degrees, the daytime temperature suitable for growth is about 20 degrees, and the night temperature is about 15 degrees, and the growth is stopped when the temperature is lower than 3 degrees, the quality is not good, and the yield is low.

Carrots can extract tundra only under lighter conditions.

As a result, intermediate lighting is needed, which is more sufficient, and the leaves grow well. Lack of light tends to make the petioles thinner. The roots of carrots are more developed, the leaf area is smaller, and they are relatively drought tolerant, so carrots do not have high requirements for water in the seedling stage, and the soil moisture content of carrots is about 70% when they are in the middle stage, and they are short of water for a long time, and carrots are relatively small, with many lateral roots, and are easy to produce rotten roots.

Carrots prefer thick, sandy soils and have a greater need for potassium, followed by nitrogen fertilizers, and phosphate fertilizers with the least demand. With too much nitrogen fertilizer, carrots tend to grow longer.

Carrots have high soil requirements, loose soil or prefer sandy soil. Otherwise, it will become rough, the lateral roots are prominent, and there are many forks, and 4 tons of 90 kg of compound fertilizer can be used for 1 acre of land.

The resting depth can be combined with 30 cm. There are many cases where carrot seeds have burrs, gasoline absorption is difficult, germination is slow, and the buds are uneven.

Carrots should be prevented from drought within 60 days after sowing, and attention should be paid to moderate irrigation. Therefore, there is a saying that "after sowing, water three waters, protect the seedlings and Qi Miaowang". "Three waters" are watered when sowing, watered when they are not dry, and watered when the young buds are topped with soil.

In particular, drought in 4-7 true leaves has a great impact on root rooting, and the root splitting rate also increases. Therefore, it is necessary to maintain proper humidity, as excessive humidity will promote the occurrence of diseases and increase the rate of fibrous roots. According to the law that carrots mainly absorb nitrogen in the early stage, phosphorus and potassium absorption in the early stage have the greatest impact on root expansion, calcium absorption is lower than potassium and nitrogen, and higher than phosphorus and magnesium fertilizer absorption, focusing on the application of sufficient basal fertilizer and timely topdressing.

Planting: Melon seedlings from cotyledons to have 4 true leaves, generally in early spring when the temperature is relatively low, it is advisable to use the seedling age of 20 25 days of older seedlings planting. When transplanting seedlings in summer, the seedling age should be 8 to 12 days.

Seedling: When the seedling has 4 or 5 true leaves, the seedling should be determined.

Choose the best planting method by the variety of carrots, the varieties are different, the planting time is different, and the temperature required is also different.

In order to determine the best planting method for carrots, first of all, we must choose the right land to plant, and temperature and climate are more important, so we must pay attention to these things when planting live radish.

When it comes to turnips, everyone is familiar with them, and there are still many people who like to eat turnips in people's daily lives. On top of that, dishes made from radishes are very tasty and relatively nutritious. Eating radish high can not only promote the body's digestion and absorption, but also inhibit the secretion of gastric acid.

The most surprising thing is that radish has the effect of improving the body's immunity. The effect is really good, so a lot of people like it. Eat it, but for vegetable farmers, growing radishes is not so simple.

So how can we grow radishes in a high-yielding and high-quality way? Let's take a look.

If you want to grow high-quality radish, you must first choose the planting step. Fortunately, turnips are highly adaptable to the soil and can grow properly on most lands. So, comparatively, the steps to choose the seeds are a bit simpler, but if you want to get a higher yield of turnips, you can also choose where the radishes grow in fertile soil.

This will make the cultivation of radishes more productive, and everyone should know that the roots of radishes are relatively developed, so the deep soil has a greater impact on the yield of radishes, so everyone should pay more attention when choosing the land.

It is important to pay attention to handling before sowing. In general, the seeds need to be treated before sowing vegetables. Radishes are no exception, and the seed treatment of radishes requires a total of two steps.

The first one is to choose the seeds. You can start by removing the damaged pellets from the seeds and then try to choose the ones with intact pellets to improve the germination rate of the seeds. As for the second point, it should be noted that when choosing seeds, it is best to choose new seeds, remove the hard bristles on the seed skin before sowing, and then soak the seeds to maximize their effects and improve the emergence rate.

Another thing is to deal with the soil, but specifically, what everyone needs to do is loosen the soil and weed. In general, during the summer and fall, there will be more rainfall. If it rains continuously, it will cause the soil to clump.

At this time, the oxygen content in the land naturally decreases. This soil is definitely not suitable for the growth of turnips, especially when the resistance of radish roots is relatively weak at the seedling stage. If there is not enough oxygen in the soil, it will be greatly affected.

It affects its growth, so what everyone has to do at this point is the steps of loosening the soil and weeding to ensure that there is enough oxygen in the soil for the turnips.

The last thing that everyone should pay attention to is that the summer and autumn sunshine is very strong and the water evaporates quickly. If it doesn't rain for a long time, everyone needs to water the radish in time, but watering is also special. To water the radish, it is best to use a small amount of watering method to ensure maximum moisture in the soil.

But another point to note is that if there is a lot of precipitation at this time, there will also be standing water in the field, and everyone needs to drain it in time, otherwise it will affect the growth of radish roots. So in general, everyone needs to do the above things in order for the radish to grow properly. I'm sure everyone will end up with a good person.

Try to choose deep, loose soil and apply base fertilizer after deep ploughing. Radish has relatively high requirements for water, especially in the early stage, it is necessary to water more to meet the water demand of radish during this period, and water as much as possible.

1. Radish is more afraid of moisture, so you should choose a well-drained field.

2. It is better to choose fertile plots, deep and loose soil for planting.

3. Before sowing, sufficient base fertilizer and insecticidal drugs should be applied as soon as possible.

1. Soil, radish is a relatively easy vegetable to grow, and the requirement for soil is that the soil is loose and weakly alkaline.

2. The requirement of water, people who have eaten radishes know that radishes contain a lot of water, so they should be watered more when planting radishes.

It is advisable to choose loose and deep loam soil. Watering is generally done once every 10-15 days, but should be stopped a week before the harvest. The fertilizer should be chicken, duck, pig manure, human manure or chemical fertilizer at home, and should not be too close to the roots of the radish seedlings when fertilizing.

Radish seeds, it is better to choose new seeds of the year for sowing. The germination rate of new seeds is high, and the interval of more than one year is old seeds, and the germination rate of old seeds is too low to be selected. Radish seeds should choose high-quality seeds with good maturity, full grains, and high germination rate.

Varieties of radishes are selected and planted according to local consumption habits and uses. Fertilization and land preparation. Try to avoid continuous cropping with cruciferous vegetables, and clean up the previous crops.

Before sowing seeds and radish seeds, seed disinfection treatment is required to prevent diseases at the seedling stage.

To choose very high-quality seeds, the soil for planting must be very fertile, and the water must be fertilized, and the temperature at the time of planting should also be suitable, so as to ensure that the whole radish seedlings can be ensured; When planting, we must pay attention to applying base fertilizer in advance, watering in advance, and the temperature should be suitable when planting, and there should be a certain amount of sunshine.

Land preparation: Radish planting should be planted in a deep soil, rich in organic matter sandy loam soil, not clay or too sandy soil planting. Be careful not to have problems with chaff.

The first seedling of carrot should be carried out when there are 1 2 true leaves after the seedlings emerge, to prevent the seedlings from crowding each other, and to remove the seedlings that are too dense, overlapping seedlings, miscellaneous seedlings, inferior seedlings, and diseased and insect seedlings, and keep the plant spacing of 3 5 centimeters slippery vertical rice.

The second seedling is carried out within 7 10 days after the first seedling, focusing on the dense seedlings to keep the plant spacing at 7 10 cm, and then irregularly carrying out 2 3 times of seedling, through multiple seedlings, and finally the seedlings are kept 10 15 cm square.

Carrot seeds are thin and small, the soil is slow and noisy, and it is the high temperature and rainy season after sowing, which is most likely to lead to weed breeding, therefore, it is necessary to combine weeding when thinning seedlings, otherwise, carrots will inhibit the growth due to a large number of weeds.

Large-scale cultivation due to the use of weeding labor, can be used 25% of the weeding ether of the fiber hall weeding, 1 kg per mu with 50 60 kg of water, after sowing when the compartment surface is wet, then sprayed on the compartment surface, the weeding effect of monocotyledonous weeds is more obvious.

1. Seedlings and seedlings. In the growth stage of radish seedlings, the seedlings should be planted in time to avoid competing for nutrients and resulting in thin growth. When thinning seedlings and setting seedlings, pull out diseased seedlings, weak seedlings, insect seedlings, retain strong seedlings, and at the same time pull out weeds in the field, spray 800 times of new high-lipid film in time to prevent bacterial infection, improve the ability to resist natural disasters, improve photosynthesis intensity, and protect seedlings to thrive.

2. Do a good job of topdressing at the seedling stage. According to the growth of radish, do a good job of topdressing in a timely and targeted manner, generally apply 8-10 kg of urea per mu, and spray 800 times of new high-fat film in combination with top dressing to improve the utilization rate of active ingredients in fertilizer.

3. Do a good job in pest control. Should do a good job in insect pest control, radish seedlings common insect pests are jumping beetles, leaf bees, bees, etc., according to the requirements of plant protection to select targeted pesticides for prevention and control, and with the spraying of new high-fat film 800 times to improve the utilization rate of pharmaceutical agents, consolidate the control effect.

Before planting carrot seedlings, two seedlings should be interspersed, the first time the seedlings are carried out when the seedlings have 2 to 3 leaves, and the seedling spacing is 3 cm, so as to facilitate the seedlings to be complete and strong; When the seedlings have 4 to 5 leaves, the second seedling (seedling) is carried out, and the seedling spacing is 8 to 10 cm. Every time the seedlings are thinned, it is necessary to combine cultivating the soil and pulling out weeds. Before sealing the ridge, after watering or after rain, it is necessary to cultivate the soil 2 to 3 times, and at the same time combine the cultivation of the soil.

The general row spacing of 5-inch ginseng is 20cm, and the plant spacing is 15cm. You can pull out the excess with your hands. The seedling time is about 10 cm for seedlings.

The row spacing of 7-inch ginseng plants should be a little wider.
