How to delay the growth of wheat at seedling stage?

I strongly recommend that you let the wheat see less sunlight, because the growth of plants is the result of photosynthesis, if the wheat does not see the sun, then it can grow very slowly, and it will not delay the final growth of the wheat, which is a better way.

This method is relatively simple, you can make the wheat see less sunlight, so that it will not photosynthesize, and it can also make the wheat grow very slowly, and most importantly, it will not delay the final fruit of the wheat.

If you want to delay the growth of wheat, then you can completely make the wheat less sunlight, so that the wheat can slow down the growth and will not cause harm to the growth of wheat, which is relatively simple.

Years of experience, mainly to control the temperature, light and moisture at the seedling stage are secondary.

This problem is more difficult, for example, the water it needs to grow, you need to water a little less, you need the soil to be moist, you make the soil dry. This question is more difficult, if you need it, it is better to ask an expert, and it is more professional.

If you want to delay the growth of wheat, I strongly recommend that you make the soil dry and water the wheat less, so that the wheat will grow very slowly and will not delay the last scion.

The seedling stage is also called the "wheat rejuvenation stage" can make the land dry a little, so that the wheat seedlings will lack water, and the lack of water will slow it grows. <>

It is advisable to water less and let it grow a little slower. Letting it see less sunlight will encourage it to grow, and if you let it get less direct sunlight, the wheat will grow a little slower. It is better to ask an expert about this specific method.

In warmer areas, there is a saying that "the autumn equinox is early, the frost falls late, and the cold dew is just right for planting wheat", and it is precisely because of the differences in climate in various places that there are two different proverbs for autumn sowing wheat, which are neither conflicting nor contradictory, and classic and practical because of their trans-regionality. Take the wheat planting in Jiaodong area as an example, in addition to the above-mentioned cold dew wheat farmer proverb, in the actual planting, there should be a sequential sowing arrangement according to the hilly mountains, depressions and river sandwich land. In Ah Xi's memory, the self-reserved land in the hills of his childhood was always planted first, and the more fertile plots were planted later.

The sowing time will be slightly different, in the southeast of the hometown of the Agricultural University, it is also the best time to plant wheat, according to the season, today is just the cold dew, can be suitable for the sowing of wheat, the old people in the countryside often say: "the autumn equinox is early, the frost falls late, and the cold dew is just right to plant wheat." 3 to 5 days before entering the freezing period, pour frozen water to keep the wheat seedlings safe for wintering.

Where conditions permit, you can use crushed straw, dead leaves, weeds, plant ash, sand, etc. to sprinkle on the wheat seedlings in the wheat field to prevent frostbite from severe cold and low temperatures. In the rainy areas of the south.

The winter management of winter wheat should be watered well and thoroughly irrigated with winter water during the heavy snow solar term, and it can not be watered during the cold solar term, because the freezing is very deep in the big cold solar term, and the watering water can not quickly penetrate into the ground, there will be open water, and the open water will freeze at night, resulting in the suffocation of wheat seedlings. The effects of ecological conditions (latitude and altitude), developmental characteristics and pre-winter accumulated temperature are somewhat complex, so it is only necessary to arrange sowing according to local planting experience. Our northern region is generally before and after the cold dew, mainly depending on the moisture.

Cold dew and frost. There is a well-known proverb "white dew early, cold dew late, autumn equinox wheat planting is the right time", it is the sowing period of wheat, it is considered that the white dew is early, and it is too late to reach the cold dew season, only the autumn equinox is suitable for sowing. It is also a double rush season, harvesting autumn crops such as peanuts and corn, and at the same time starting the annual winter wheat sowing.

Therefore, in our rural areas, the cold dew solar term has also become the standard time for farmers to sow winter wheat, and the sowing date is advanced or postponed, which is calculated according to this cold dew.

For the fields with weak growth, it is still important to use rejuvenating fertilizer in a timely manner. The most suitable temperature for wheat growth is 15-18 degrees, and for the lack of basic fertilizer, it is recommended to apply 10 kg of urea per mu to promote weak seedlings to become strong seedlings.

I think that if we want to increase the production rate more effectively and effectively, we can choose high-quality fertilizer and fertilize it.

As long as it is very effective to increase the speed of this growth, then you should pay attention to the time of fertilization, as well as the changes in this solar term are very important, to master the most basic skills.

The growth cycle of winter wheat should not be shortened.

However, winter wheat varieties with short growth cycles can be chosen. Such as Qimai No. 8 and Jiuchun No. 7.

The growth cycle of Jiuchun 7 is only 107 days.

WheatCultivation techniques.

The crop grows well on both acidic and slightly alkaline soils, but the most suitable soil pH is to.

Farming and land preparation.

The land preparation of the crop in the dry land should be based on the deep tillage layer year by year, combined with the application of organic fertilizer, and the improvement of water and fertilizer conservation, and the land preparation should be carried out according to different multiple cropping forms. That is, the previous harvest of the fiber earlier, such as spring corn, sorghum, tobacco, etc., the harvest should first be shallow tillage to eliminate stubble, and then deep ploughing of the kang soil, so that the stubble rots and accept the autumn rain, shallow rake after the rain, reduce evaporation; The other category, such as sweet potato, cotton, etc., has a tight harvest time, and if the conventional method is used, it is bound to delay the sowing date, which is one of the important reasons for the low yield of the crop in the southwest region. Therefore, on the one hand, the implementation of loosening soil and moisture between the rows in the previous crop and later period, and then plowing and leveling when planting wheat; On the other hand, it is advocated to dig potatoes, level the ground, fertilize, sow and other continuous operations to ensure that the crop is sown in a timely manner.

High-yield technology. 1. Pay attention to the selection of high-fertilizer and water plots. High-yield and high-quality crop varieties require that soil nutrients must be comprehensive and sufficient, in order to meet the needs of high-yield cultivation, so it is advisable to choose plots with high soil fertility and good watering conditions, increase organic fertilizer, and adopt formula fertilization technology.

Pick up the stool. 2. Pay attention to late sowing at the appropriate time, and determine the appropriate basic seedlings according to the characteristics of the variety. It is necessary to prevent excessive sowing volume, resulting in passive post-management.

3. Pay attention to prevent lodging and reapply jointing fertilizer. Some of the high-quality crop varieties promoted are not resistant to lodging, especially for wheat fields with too large groups, a chemical control treatment must be carried out before returning to jointing, and paclobutrazol or wheat yefeng can be sprayed. It is necessary to reapply jointing fertilizer to control the formation of excess falling ears and promote large ears and more grains.

4. Pay attention to watering grouting water, wheat yellow water, and spraying foliar fertilizer to prevent premature aging. Watering grouting water plays an important role in increasing granularity weight and preventing dry and hot air. In dry weather, the use of wheat water is conducive to intercropping and preventing premature aging.

In the first half of May, combined with the prevention and control of pests and diseases, spray 2 to 3 times of foliar fertilizer, such as potassium dihydrogen phosphate, which can reduce the harm of dry and hot air and increase yield.

5. Pay attention to the prevention and control of pests and diseases. Generally speaking, high-quality crops are more susceptible to pests and diseases, such as sheathrody and powdery mildew, and aphids occur earlier and heavier than conventional varieties. It should be prevented and treated as soon as possible according to the forecast.

6. Spray the crop treasure once when the crop has just broken and reached about 60% to 70% before heading and flowering, so as to activate the biological enzyme activity in the crop, promote coordinated growth, enhance the photosynthesis of functional leaves, significantly reduce the empty stubble rate, improve the seed setting rate and 1000-grain weight, so as to achieve the effect of increasing yield.

Growing wheat is a complex process that needs to be managed according to the climate and soil conditions of the region. Here are some management recommendations for wheat sowing time:

Soil preparation: Before sowing wheat, soil preparation is required, including ploughing, ploughing, fertilizing, etc. Make sure the soil is adequately nutrient and hydrated to promote the growth of wheat.

Sowing time: The best time to sow wheat varies from region to region and variety, and is generally sown in spring or autumn. When choosing the timing of sowing, the local climate and soil conditions need to be taken into account to ensure that the wheat can grow under the most suitable conditions.

Sowing amount and depth: When sowing wheat, it is necessary to control the sowing amount and depth to ensure that the sowing amount and depth are uniform per square meter. In general, wheat is sown at a depth of 2-4 cm and at a rate of 100-150 grams per square meter.

Irrigation management: During the growth of wheat, irrigation needs to be carried out in a timely manner according to the soil moisture situation. At the beginning of wheat growth, it is necessary to keep the soil moist so that the wheat can germinate smoothly. In the later stages of wheat growth, the amount of irrigation needs to be gradually reduced to help the wheat mature.

Pest control: In the process of wheat growth, it is necessary to detect and deal with pests and diseases in time to ensure the growth and yield of wheat. It can be controlled by chemical agents, biological pesticides and other methods.

In short, for the management of wheat sowing date, it is necessary to comprehensively consider multiple factors such as planting environment, climate, soil, etc., and adjust and manage according to local conditions.

Wheat is a very important food crop, and its growth process is very complex. The whole growth process can be divided into three stages: germination and growth, flag leaf growth and heading maturity.

The germination period refers to the process by which seeds germinate in the soil. When temperature, humidity and light are suitable, the seeds absorb water in the soil, allowing persistent buds to stretch out and form a root system, while the tips sprout. At this time, the growth rate of wheat is relatively slow, and you need to pay attention to moisturizing and watering.

The flag leaf growth period refers to the period from the appearance of the first leaf on the bud head to the beginning of the differentiation of wheat from the growth point (the part called the growth point has the development tissue of new shoots and leaves, which is an important part of wheat). At this stage, the growth rate of wheat is very fast, and special attention should be paid to the application of nitrogen fertilizer and potassium fertilizer to ensure the nutrients of wheat**.

Heading maturity refers to the process in which wheat grows out of the top panicle inflorescence and the grain gradually matures. At the heading stage, wheat no longer grows, but only transports nutrients to the stems and grains, so it is necessary to control the flourishing of the bottom leaves and manage environmental conditions such as light and temperature and humidity to ensure yield and quality.

In conclusion, the growth process of wheat needs to pay attention to environmental factors such as fertilization, differential watering, timely pest and disease control, and management of light, temperature and humidity. Only scientific management can obtain the fruits of a bumper harvest.

When I was young, although I often did heavy work: cutting and raking, pulling plows and rakes, cutting wheat and planting beans, pulling seedlings and transplanting seedlings, and beating rice and drying rice, every Sunday, in the morning and afternoon, I had to go to the field to cut two manure baskets of grass and send them to the production team to calculate the work. Working a lot, that is, not paying attention to how the crops grow, and never thinking about it.

Now that my daughter has asked me to plant cat grass (I didn't pay attention to it when I planted cat grass for the first time), this time I want to carefully observe the growth process of the wheat seedlings:

On the evening of March 1, I grabbed a handful of wheat grains, spread them evenly in a small box of earth, sprinkled a thin layer of soil on top, sprayed some water, and waited for the good news.

There was no movement on March 2. I put the square box in a sunny place during the day and at night, on the ground temperature.

On the evening of the third day, I found that the wheat kernels were showing malt the size of a pinpoint.

On the fourth day, the wheat seedlings sprang out one centimeter high.

No. 5 and No. 6 wheat seedlings grew upwards slowly.

This morning, I saw that the wheat seedlings had not only grown taller, but also the young leaves had grown and widened.

No matter what kind of plant, it must be moisturized by sufficient sunlight and rain in order to grow healthily.

My wheat seedling, you grow, grow! You're growing up my hope...... soon

(1) Growth period: wheat from seed germination, seedling, rooting, leaf growth, jointing, booting, heading, flowering, fruiting, through a series of growth and development processes, to produce new seeds, called the life of wheat. The number of days it takes from sowing to maturity is called the growth period.

The growth period of wheat is generally 230-270 days.

2) Growth period: According to the growth characteristics of wheat at different stages, in order to facilitate cultivation and management, the life cycle of wheat can be divided into 12 growth periods, namely seedling, three-leaf growth, tillering, overwintering, returning to green, getting up, jointing, booting, heading, flowering, grain filling, and maturity period. Among them, the grain filling stage can be divided into grain formation stage, milk maturity stage, wax maturity stage, and completion stage.

3) Growth stage: According to the characteristics of wheat organ formation, several consecutive growth periods can be combined into a certain growth stage. It can generally be divided into three growth stages.

1 Seedling stage: from emergence to emergence. It is mainly vegetative growth, that is, it is dominated by long roots, long leaves and tillers.

2 Intermediate stage: from rise to flowering. This is the stage of vegetative growth and reproductive growth, which includes the growth of roots, stems, and time, as well as the differentiation and development of wheat ears.

3 The later stages range from flowering to maturity. It is also called the granule formation stage, which is dominated by reproductive growth.
