The "Five Factors" to Realize High Quality and High Yield of Cotton in the Rainy Season

How should the growers in the rainy season achieve the high quality and high yield of cotton? It is well-known that the period during which the growth and development of cotton is most prosperous is the rainy season. However, due to the occurrence of natural disasters such as droughts and floods during the rainy season, the cotton growers are likely to suffer economic damage.

To this end, cotton growers should pay special attention to cotton planting and management in the rainy season. The following Xiaobian will introduce to you the “five factors” for realizing the high quality and high yield of cotton in the rainy season.

First, control the fertilizer

In the rainy season, the long-standing branches and leaves of cotton will increase the number of buds, and the demand for fertilizer and water will reach its peak. It should be top-dressed in a timely manner to guard against premature aging. However, due to the relative abundance of rainwater in the rainy season, it is extremely beneficial to the exertion of various fertilizer effects, resulting in a long and mad growth of cotton plants. Therefore, while top dressing, it should also be done:

1, the base fertilizer is sufficient, the amount of fertilizer in the cotton field should be less or not Shi Shi, and pay attention to clear the ditch drain, beware of waterlogging.

2, the growth retardation of cotton plants, red stems to the top, small yellow-yellow cotton fields should be applied early and increase the amount of fertilizer, such as urea can be used in about 8 kg per mu, but also the whole hospital spray cotton Zhuang Ti Ling. In addition, if a continuous drought occurs and the soil moisture content is less than 60% of the field water capacity, it should be replenished from time to time.

Second, appropriate control

After entering the rainy season, the cotton plants are prone to madness, which causes the rapture of the buds. In time, the growth of the cotton plants can be stabilized by the use of dildoamine or auxin, which can improve the plant type and increase the number of buds. The method is: during the early flowering period of cotton in the early rainy season, 6-8 milliliters of assisting factor or 1.5-2 grams of salicylamine per acre is used to spray 30-40 kilograms of water all over the field.

Into the middle of the rainy season, about the end of July to early August, can be used about 3 grams of dilute amine powder, spray 40-50 kg of water.

Third, diligent pruning

Due to the accelerated growth of cotton plants in the rainy season, their axillary buds are also prone to occur. Therefore, it should be manually erased when the rain stops and the timeliness. When the cotton plant grows to a predetermined plant height, it is timely (approximately mid-to-late July) topping in order to break down and suppress the top biotic advantage, reduce the unnecessary consumption of nutrients in the upper non-effective shoot, and promote boll development.

Fourth, scientific management of worms

The occurrence of various pests and diseases has a significant relationship with the rainfall conditions in the rainy season. If the drought is not conducive to the hatching of H. armigera eggs and larval development, but a large amount of rain and precipitation will hinder the hatching of eggs, especially the heavy rain has a strong flushing effect on the eggs and newly hatched larvae. If the rainfall in the rainy season is small and even, it will help the outbreak of the bollworm. However, if there is little precipitation during the rainy season and the drought is severe, then it is beneficial to the propagation of red spiders.

On the contrary, if there is continuous rain during the rainy season, the cotton plant is very prosperous, the madness grows seriously, and the field is poorly drained. The cotton plants are susceptible to withering and verticillium wilt, and at the same time triggering the emergence of the rot disease. Therefore, the prevention and control of cotton pests and diseases should be combined with the weather conditions in the rainy season, reasonable selection of pesticides, scientific control, can only do more with less.

V. Suitable for natural disasters

The entry into the rainy season is an easy-to-produce period such as drought, waterlogging, hailstorm, and high winds. On the basis of strengthening defense, we must also respond to irresistible disasters and take measures to save them so as to reduce the damage. For example, the cotton fields damaged by hail shall be timely filled with fertilizer and promote recovery as soon as possible; followed by timely pruning, chemical control, and prevention of pests and diseases.

For the cotton affected by the disaster, one is to clean up and clear the drainage system as soon as possible, and remove the accumulated water; followed by cultivating the loose soil, increase fertilization materials, prevent defermentation and drought.
