Analysis Of The Main Reasons For The Decrease Of Mid Autumn Silkworm On This Year

in autumn-bred silkworms Sooner or later, it is related to the high quality and high yield of the mid autumn cocoon. When to raise the mid autumn silkworm, the date of the mid autumn silkworm breeding date should be determined by the production and development of mulberry trees in the summer and Autumn period, the number and proportion of seeds planted in the late autumn and autumn silkworms, the date of seed production and the weather conditions of the neighboring counties (cities, districts), and the factors such as spraying date and insect pest date of the late rice, and finally decide the date of seed production. Jiaxing's main silkworm producing area, Xiuzhou District, decided that this year's mid autumn silkworm would be released in August 24th, 1 days earlier than the first year, and in August 26th. At present, 2858 pieces of mid autumn silkworm eggs have been set up in the region, and 6015.25 pieces of silkworm eggs have been raised, which has reduced 3157.25 pieces and reduced 52.49% by last year. It is also understood that Tongxiang, Haining and other counties and cities will also distribute mid autumn silkworms on the same day, and Haiyan County will be postponed for a day.

The main reason for the decrease of midautumn silkworms is:

First, the cocoon price factor. The price of spring cocoons this year is only about 1550 yuan per load, which is about 650 yuan a year, down by nearly 650 from 2200 yuan a year, and the decline of cocoon price has seriously affected the enthusiasm of the broad masses of sericulture farmers to cultivate silkworms.

The two is environmental factors. Silkworms are very sensitive and require high environmental requirements. Air or mulberry leaves contain trace harmful substances that can affect silkworms. In recent years, due to the impact of global warming, rice and other crop diseases and insect pests have increased significantly, and the number of insect pests in late rice has increased significantly, leading to the widespread use of pesticides. In addition, the mulberry garden itself has many pests and diseases in autumn, and it should be treated many times. There are more rice and Sansono Osa before and after mid autumn silkworms, so that the mid autumn silkworms are easy to cause micro pesticide poisoning. At the same time, the mid autumn silkworm season is not only characterized by high temperature, but also poor quality of mulberry leaves. It is easy to cause silkworm disease. In recent years, the yield of Mid Autumn Festival is not high and the quality is not good. This is also one of the main factors that reduce the rearing quantity of mid autumn silkworm.

　　 The three is the cost factor. cost Factors mainly include two aspects, on the one hand, the cost of agricultural materials is rising. According to the preliminary investigation, the cost of mulberry mulberry silkworm cultivation is mainly about silkworm medicine with chemical fertilizer, pesticide and disinfection and disease prevention. The cost of the silkworm medicine has increased by about 10%, and the cost of labor has risen even more. At present, a male laborer is working for about 80~100 yuan a day, and the female labor work is about 60~80 yuan a day, and the labor cost ratio is about 20% higher than that of last year.

The four is labor factor. Sericulture is a labor-intensive industry. Because traditional sericulture production is "bitter, dirty and tired", most young people in the countryside do not want to engage in sericulture work, and do not want to learn mulberry silkworm breeding technology. Sericulture farmers who are engaged in sericulture are aging gradually. Therefore, the labor problem has also become an important factor restricting the development of sericulture production.

The five factor is the external silkworm eggs. Because of the restructuring of the overseas silkworm farms and the factors such as oversupply of silkworm eggs this autumn, the number of silkworm traffickers has increased greatly. Many silkworm traffickers have ignored the regulations on silkworm eggs management in Zhejiang Province, and tried every possible means to sell the silkworm eggs to our area through improper channels, which has affected the normal supply of silkworm eggs in our area.

　 The six is the area factor. The leaf area of mulberry garden has been significantly reduced. This year, the greening of the two sides of the high speed railway and expressways has reduced about 500 mu of the mulberry garden. Since the end of last autumn silkworm production, the silkworm farmers have cut down the mulberry garden to reduce fruit and seedlings, and add some other capital construction land and demolition. In less than 1 years, the Xiuzhou area has been reduced. Mulberry garden The area is over 1200 mu.
