What are the growing conditions required for cotton cultivation and why?

1.Abundant heat: The lower the average daily temperature, the more accumulated temperature is required from sowing to emergence. From flowering to flocculation stage, the thermal conditions not only affect the yield of cotton, but also affect the quality of cotton.

2.Sufficient light: Cotton is mostly early-medium-ripening, early-maturing and extra-early maturing varieties, which are insensitive to light length. It is a light-loving crop and is suitable for growing under sufficient light conditions. The light compensation point and light saturation point of cotton are both high.

3.Sufficient water: Water is an important component of cotton, and cotton needs to absorb water from the soil to grow.

4.Fertile land: The physicochemical and biological properties of the soil in cotton fields greatly restrict the yield and quality of cotton. Soil moisture, nutrients, temperature, air, salinity, texture, etc. have a great impact on cotton growth.

With the gradual improvement of the quality of life, many people will choose to grow some crops in the countryside to obtain additional income, which is also a very good method. So many people choose to grow cotton, because the sales of cotton are also more, so what are the requirements for planting cotton for climate? At the same time, it is also necessary to determine different planting locations according to different temperatures.

First, the requirements for temperatureIn fact, when farmers choose to plant cotton or harvest benefits, they must have certain requirements for temperature, and the requirements for cotton are very high, with a minimum of more than 15. Therefore, cotton must not be planted in areas with low temperatures, and in this case, you will definitely not be able to get better profits. And the most important thing about cotton is quality, because the quality of cotton can ensure that the best cotton can have better sales in the future, and if the temperature is too high such as 36 or more, there will be some bad phenomena, such as cotton no longer grows tall or has stopped growing, so the temperature requirements are very strict.

Second, sufficient sunlight In fact, cotton should be planted in full sunlight, because cotton must use sufficient sunlight for photosynthesis to transform some nutrients. Within a certain range, photosynthesis will increase with the increase of light intensity, and at this time, sufficient sunlight will ensure the premise of whether the cotton grows well. In some parts of China, in fact, the sun is not sufficient, and there is a lot of rainy weather, in this case, cotton must not be able to be grown.

Because if cotton does not grow better, the quality of cotton will not be improved, and the next year's income will not be better. <>

3. Ensure sufficient water Cotton is also a plant that is not very drought tolerant, so it is necessary to keep enough soil moisture, in some places it is actually relatively arid, and water sources are relatively scarce. At this time, farmers can not choose to plant cotton, because planting cotton must control the content of water and fertilizer, at this time, if water is a relatively scarce component, do not consider planting cotton.

When planting cotton, there are certain requirements for the corresponding temperature, and there is a certain demand for temperature in the production process of cotton, and the minimum critical temperature for cotton germination is about 10 to 12 degrees Celsius, and the most suitable temperature is between 28 and 30 degrees Celsius. If the temperature is too high, when the temperature is above 35 degrees Celsius, it will inhibit physiological activity, and when the temperature is high, it will also cause pollen cultivation failure and loss of fertilization ability. When the temperature is too low, it will make the reducing sugars and other substances produced by photosynthesis unable to be converted, and the deposition function of cellulose will be terminated accordingly.

Therefore, in the process of planting cotton, it is necessary to grasp the appropriate temperature.

The climate requirements for planting cotton are that the climate must be very warm, and it must be planted in summer, and the weather in the place where it is planted is relatively dry, and it cannot rain often, and the sunshine time must be sufficient, which are the requirements for the climate when planting cotton.

The temperature should be kept around 20 degrees. Such an environment is very conducive to the growth of cotton. In the case of maintaining light, it is also necessary to water and fertilize in time to be able to make him have better growth more effectively.

Light cotton is a light-loving crop, suitable for growing under sufficient light conditions, light compensation point and light saturation point are high, according to the determination of cotton single leaf light compensation point is 750 1000 lux, light saturation point is 7 8000 lux, under normal circumstances, cotton leaves to light intensity suitable range of 8000 70000 lux, in this range the photosynthetic intensity increases with the increase of light intensity. <

Soil Cotton needs water and nutrients to grow and develop, mainly from the soil through the root system, and the required temperature and air are partly taken from the soil, while at the same time requiring the mechanical support of the soil to grow. The physicochemical and biological properties of cotton soil greatly restrict the yield and quality of cotton, and soil moisture, nutrients, temperature, air, salinity, texture, etc. have a great impact on cotton growth.

3. Water cotton growth needs to absorb water from the soil, the physiological water requirements of each growth stage are different, the water content of the soil layer from sowing to the emergence of seedlings accounts for 70 80% of the water holding capacity in the field, the soil moisture content of 0 40 cm at the seedling stage accounts for 60 70% of the water holding capacity in the field, the water content of the soil layer at the early bud stage accounts for 65 75% of the water holding capacity in the field, and the water content of the soil layer at 0 80 cm after the full bud period accounts for 70 80% of the water holding capacity in the field, and cannot be less than 60 65%. It is advisable to keep the relative moisture content of the soil at 55-70% at the flocculation stage. According to relevant studies, about 2 3 of the water consumed in cotton fields during the whole growth period is transpiran, and 1 3 is consumed by land evaporation. <>

Cotton fiber can be made into a variety of fabrics, from light and transparent voile to thick velveteen and canvas, suitable for all kinds of furniture fabrics, clothing cotton, industrial fabrics, etc. Cotton fabric is strong and wear-resistant, able to be washed and ironed at high temperatures, and cotton cloth is comfortable to wear due to its rapid moisture absorption and dehumidification. Through other finishing processes, it can also make the cotton fabric waterproof, mildew-proof and anti-fouling; Improve the wrinkle resistance of the fabric, so that the cotton fabric is less hot or even does not need to be ironed; Reduce the shrinkage of the fabric when washing so that the shrinkage rate should not exceed 1%.

The color of the cotton raw cotton that is normally mature and normal is white and milky white, which is called white cotton, and the raw cotton used in cotton spinning mills is mostly white cotton. In the late stage of cotton growth, the cotton boll dies after frostbite, and the pigment on the boll shell is dyed on the fiber, which makes the color of the original cotton yellow, and the yellow cotton is generally a low-grade cotton, and the cotton mill has only a small amount of application.

The requirements for the production process are that the temperature must be controlled at about 23, not too hot, there must be sufficient precipitation, there must also be a strong ventilation environment, there must be sunlight, and the main use is that it can be used to make clothes.

The environment is required to be very warm, the temperature of the environment is also relatively high, the sunlight exposure time is relatively long, the humidity is also very high, and the environment is relatively arid. The use of cotton is that it can be used to make quilts, mattresses, clothes, down jackets, and pillows.

There are particularly high requirements, the general planting environment is in the place where the temperature difference between day and night is relatively large, and the tropical environment, such as Xinjiang, can be made of quilts, cotton clothes, craft cloth or furniture.

There are requirements for soil, for temperature, for cold and hot temperature differences, for drainage, for light, the main use of cotton is to make clothes, can be made into quilts, made into fabrics, is the raw material of many things.

It is suitable for growing in some conditions with sufficient light. And I also like this kind of place very much, and the soil needs to be very moist. And it has to be particularly fertile.

When planting plum blossoms, I still like some hot weather, it is better to be dry, have sufficient sunlight, and the time is relatively long, so that the color of the growing cotton will be particularly good.

It needs to be planted in a place where the sun is more abundant, the sunshine hours are longer, and the drought is a little drier, so that the yield of cotton can be guaranteed.
