Hunan Anxiang County Cotton Production In 2012 Is A Foregone Conclusion.

2012

The average density of the whole county in Anxiang province was 1105 plants per mu, 50.1 bolls per plant and 55454.8 acres per mu, which were 6, 5.1 and 5951.8 more than the same period last year.

According to last year's standard, boll weight and lint percentage are estimated to yield about 108 kg of lint per mu, which is 13.7 kg higher than that of last year, and the yield increased by 14.5%.

In 2012, although the early stage of continuous disaster, but after July, the weather has been better, it can be regarded as a good year, compared with the previous year, a large increase in production, due to serious disasters last year, this is a restorative growth.

There are 3 main characteristics of growth:

1. The percentage of rotten peaches is small.

According to the investigation of seedling point in September 15th, the number of rotten bolls per plant was 2.4, accounting for 4.7% of the total number of bolls, which was about 1/3 of the general year.

This is mainly due to less rain and sunshine hours.

According to meteorological data, the rainfall from August 25th to September 20th is only 29.2mm and sunshine hours are 202h.

2. Become more bell and concentrate faster.

Suitable temperature, light and water can make the peach grow fast and concentrate with enough fat and water.

According to seedling observation in September 15th, the number of bolls per plant was 9.8 more than that in the same period last year.

From August 15th to September, 5 days become 1.63 peach.

The effective accumulated temperature from August 15th to September 10th is 768.5 degrees, 42.4mm and sunshine hours 203.9h, respectively, which are 11.6 degrees, 8.6MM and 14.7h more than the same period last year.

What's more, this year's rainy season is mostly concentrated in the evening. The number of sunshine hours is 0 days is only two days, and there is no continuous concentration. The rainfall at the same time last year is concentrated in two periods. There is a period of sunshine time of 0 consecutive days for 6 days.

3, there is a certain degree of premature senescence.

This year the whole county of Anxiang

Although not affected by natural disasters such as temperature and temperature, about 30% of cotton fields showed signs of severe premature senescence of yellow leaves and red leaves.

The main reason is that red leaf stem blight is common in our county in recent years. Some old cotton fields use less nitrogen fertilizer, potassium fertilizer and organic fertilizer, but also have a certain relationship with varieties.

This year, compared with 2011, there was a significant decrease in the area of premature senility.
