Mei Yu Affects The Growth Of Cotton And Whether Cotton Can Survive In The Changjiang River Valley.

Every summer in early summer (mid June to mid July), all parts of the Yangtze River Basin have to experience a plum rain period. This year is no exception. It seems to come earlier. The proverb: "rain hits Huangmei head, forty-five days without sun" is the most appropriate description of it.

However, the continuous plum rains have been suffering from local cotton farmers.

Growth has had a great impact.

In the main cotton producing area of Anhui, cotton growers have complained about this rainy season. Frequent rains caused the loss of nutrients in cotton fields, resulting in a serious shortage of cotton nutrition supply. If such rainy weather continues, whether cotton can survive is a problem.

Local cotton growers say that the growth of cotton is obviously less than that of last year.

In addition to the Anhui area,

Most of the main cotton producing areas have suffered the same situation.

It is understood that the early pplanting of cotton plants has been buds, and that is when enough sunlight and temperature are needed. At this time, when the weather is cloudy and rainy, the buds will usually stop growing or appear "wilting", which will have a great impact on the later output of cotton.

At present, due to the local planting pattern, and now the plant type is not yet big, the shade is lighter, and the phenomenon of rotting buds in plants and stubble is also lighter.

According to agricultural experts, continuous rainy weather can easily lead to a large area of cotton pests.

Cotton enters the critical period of growth, and its growth environment will have an impact on the future yield and quality.

Not only is the weather not strong this year, but also

There has also been a sharp decline.

According to the national cotton market monitoring system data, the actual sowing area of the Yangtze River Basin in 2015 was 7 million 947 thousand mu, down 37.2% from the same period last year. The actual sowing area in Jiangsu, Hubei, Jiangxi, Hunan and Anhui decreased by 51.6%, 42.3%, 37.9%, 36.3% and 22.4%, respectively.

According to the data of the National Bureau of statistics, the total output of cotton in five provinces in 2014 was 1 million 31 thousand tons. According to the decline of 37.2%, the cotton output in five provinces is about 700 thousand tons this year.

It measures about 300 thousand tons.

This year, the decline of cotton production in the Yangtze River Basin is inevitable. Cotton farmers should actively take protective measures to minimize the impact of the weather.

Agricultural experts suggest that in the special period of Meiyu, we should first clear away the accumulated water in the cotton fields in time; secondly, we should spray insecticide on the sunny days to drive away the pests such as the blind Chinese stink.
