How Does Cotton Resist Early Maturity and Yield
At the beginning of this year, extreme weather often exposed color, especially in late March, an unusually high temperature appeared in many areas, followed by early April, and many regions have experienced significant cooling and rare snowfall. Under this kind of weather background, how can this year's cotton be planted to resist stress, early maturity, stable production and high yield?
We have 2 types of Large Diameter Hose: Frac Hose and Layflat Hose.
Frac hoses were produced through-the-weave, easy cleaning and no drying required.
Designed for long service life. Tough and durable with exceptional resistance to abrasion
And cutting for use on wide variety of environment conditions.
Protected against mechanical damages.
Very low elongation (compared with vulcanized process) under pressure, prevents hose from [snaking".
High resistance to heat, fuels, chemicals, UV, ozone, weathering,hydrolysis,and microbiological attack.
Tube & cover: thermoplastic, polyurethane (TPU)
Reinforcement: High tenacity polyester filament, circular weaving.
The special extrusion through-the-weave process gives a very strong bonding between cover and lining as well as firmly encapsulation the woven polyester.
Temperature range from -50℃ to +70℃.
We can supply frac hoses with size: 8``,10``,12`` and 16``.

In adopting measures, the following points should be grasped: The selection of good varieties should be based on strong resistance and stable yield and high yield as the main focus of the selected varieties, both with good precocity and potential for high yield, and to recover quickly after disaster, with these Article varieties should be the first choice.
Sowing during the appropriate sowing period reduces the impact of extreme weather on cotton seedlings and avoids seedling risk. Sooner or later, the maturity of cotton does not depend on sowing sooner or later. Do not look at the temperature and immediately sow. Before the temperature is stable, there will be cooling after an abnormal increase in temperature. It is necessary to rely on the safe use of herbicides, nutrient dressing, and seedling cultivating and other measures to promote Seedling strong.
According to the characteristics of different varieties and soil fertility, the planting and controlling of budding period is properly controlled, the plant height is controlled, the fruit branches are kept in each plant, and topping is performed in time, and the task of ringing is shared by individuals and groups.
The fertility process that should be mastered: South-Central and North-Western Shandong should normally bud in early June, flower in early July, complete the topping on July 15-20, and remove buds that have not yet bloomed before August 20th. To avoid extreme weather risks such as low temperature, drought, wind, and heavy rain in the later period, the cotton bells are concentrated in the 40-day period from July 10 to August 20.
Coordinating the relationship between nitrogen, phosphorus, and potash fertilizers has the effect of reducing nutrients and promoting early maturation, and potassium can prevent disease and prevent premature aging. These two kinds of fertilizers can enhance the stress resistance of cotton plants and should be applied in the base fertilizer; nitrogen fertilizer should be applied. After the flowering and bolling of the cotton plant, the top priority is applied, and the application is controlled at the seedling stage and the bud stage to prevent the vegetative body from being too large and affect the normal flowering and ringing of cotton plants. Do not use too much nitrogen fertilizer once. Once the nitrogen fertilizer, moisture, and temperature hit each other, it is very easy to cause the cotton plant to grow in length and form a large amount of shedding of the bells. The result of the shedding is excessive nutrition. The method is to spray the leaves in the middle and later stages. Timely nutritional supplements do not cause excess nutrients and nutrient imbalances.
Use good measures to promote the control of cotton in addition to water, fertilizer, cultivator and other measures, but also rely on growth regulators. Spraying DPCs mainly controls the growth of cotton plants. When the cotton plants are slow to grow or even stagnated due to unfavorable conditions, or when the cotton grows due to wind picking and other attacks, it is necessary to spray auxin (also known as gibberellin). , 920) to promote its accelerated growth; auxin can only speed up cell division, and can not provide nutrition to cotton plants, so it is necessary to combine the application of nutrients. Sometimes cotton plants grow fast, but nutrition is not enough, and it is not contradictory to need to spray both ghrelin and nutrients. Because the external adverse effects of cotton at the same time may be diversified, the measures we take should also be pluralistic. This requires the simultaneous use of various means of promoting cotton control.
Timely prevention and control of pests and diseases Extreme weather has complicated effects on the occurrence and damage of cotton pests and diseases. It is necessary to continuously track, observe and study new situations, strengthen predictions, and focus on prevention, and explore new prevention and control methods. Problems such as cotton seedling disease, angular spot disease, second-generation cotton bollworm, cotton blind caterpillar, cotton red spider and so on have been aggravated in some cotton areas in recent years. Once pests and diseases begin to occur, they must be treated in a strict and timely manner. They cannot delay time and leave no later problems. They must not blindly mix and increase their doses to prevent the normal birth of cotton. It is necessary to nurture strong Zhuang Zhuang strains by deep plowing and the addition of organic fertilizers to enhance the pest resistance of cotton. It is necessary to improve the microclimate of cotton fields and create an environment that is not conducive to the outbreak of pests and diseases.
