Common problems in potato production and their solutions
Zhaosu is located in the northwest border region, at an altitude of 1720-1860 m, with a short frost-free period and a cool mountainous climate. With the adjustment of the industrial structure, potato has become the main crop of our regiment. 1. Existing problems 1. Climatic effects From April to early May 2007, due to high temperatures and dry soil, potato emergence was difficult and seed potatoes shriveled. After emergence, there was abundant rain, causing seed rot and missing plants with gaps in the rows. 2. Poor quality of seed potatoes In 2007, seed potatoes suffered from rot, disease and damage. When cutting seed potatoes, diseased tubers were not strictly removed

What are the common problems in dryland rice cultivation?
1. How to grow enough rice seedlings under drought and water shortage conditions. The whole year's success lies in spring. This vividly and profoundly illustrates the importance of seedling raising in the whole year's production. Under this year's special conditions, growing enough seedlings is the key measure to win the battle against drought and secure a bumper harvest. To grow enough rice seedlings under drought and water shortage conditions, the first thing is to determine the seedling raising method according to local conditions, and the second is to implement the seedling raising technical measures. When determining the seedling raising method, there are three approaches to choose from for reference: first, in places where water can be obtained locally, promote

Analysis of the problems existing in the development of the eel industry and the countermeasures and suggestions
I. Seedlings and fingerlings The main species farmed for eel in China are the Japanese eel (Anguilla japonica) and the European eel (Anguilla anguilla). The resources of both the European eel... have already approached exhaustion, with annual production falling from 3,000 tons 30 years ago to 100-200 tons. From June 3 to 15, 2007, at the Conference of the Parties to the "Washington Convention" (CITES) held in the Netherlands, the European eel was listed in Appendix II of the Convention on Endangered Species of Wild Fauna and Flora, and this will be formally implemented starting in January 2009: China imports about 60 tons, or about 150 million individuals, of European eel seedlings and fingerlings annually, and farmed European eel accounts for more than 1/3 of eel production, while European eel accounts for about 40% of exported roasted eel. Japanese eel resources have also severely declined. In recent years, the seedling and fingerling resources of Japanese eel in Asia have remained at about 100 tons, and the annual catch in recent years has remained at 80-100 tons. In 2008, the output of European eel seedlings and fingerlings was about 90 tons, half of a normal year. The output of Japanese eel seedlings and fingerlings was about 35 tons, one third of a normal year. The severe shortage of seedling and fingerling resources has led to soaring prices. Moreover, artificial breeding of eel seedlings and fingerlings will not be able to form production capacity in the near future.

What are the easily overlooked problems in the process of selecting and retaining replacement gilts?
(1) The selection and retention procedure is unreasonable, and the selection process is simplified: In some pig farms, the selection and retention process for replacement gilts is very simple, with no fixed procedure. It is only after the breeding pigs finish testing that a simple evaluation is made and they are selected and retained. This can easily lead to an imbalance in the number of animals retained from each bloodline and a decline in the production performance of breeding pigs. Therefore, the selection and retention of replacement gilts must rely on a fixed procedure. Generally, the selection and retention of replacement gilts must go through three processes: primary selection, intermediate selection and final selection. Primary selection is when moving from the farrowing stage to the rearing stage, determining a candidate group 4 times the number to be retained for breeding; intermediate selection refers to the period from nursery to fattening

What problems exist in China's fox farming industry? A few suggestions for reference
Over the past 20 years, China's fox farming industry has made considerable progress, but through our 10 years of fairly systematic investigation into the current feeding conditions of fox farms and households, we have found some noteworthy problems that affect reproduction and fur quality. The specific situation is reported as follows. 1 Feeding and feed Currently, fox farms (households) across the country all use single-cage rearing in courtyards; they use complete feed supplemented with cornmeal, sea fish, freshwater fish, beef liver, various meat trimmings, and also add a small amount of other ingredients, boiled into a cooked porridge for feeding. Young foxes are fed 3 times a day, and adult foxes are fed 2 times a day.

Common Problems in Fish Ball Production and Sale and Their Solutions
I. The Significance of Fish Ball Production China ranks first in the world in total freshwater fish output and is also the world's largest freshwater fish farming country. China has uniquely advantageous resources for developing the deep-processing industry of surimi foods. In 2004, the national aquatic product output was 48.55 million tons, an increase of 3.2% over the same period in 2003. From January to November, freshwater product output was 16.69 million tons, up 5.9% year on year; marine capture product output was 12.87 million tons, up 2.1% year on year; and mariculture product output was 10.50 million

What are the two major problems commonly seen in garlic cultivation?
In recent years, in the main garlic-producing areas such as Jinxiang, Juye, Cangshan, Zhongmu, and Kaifeng, quite a few problems have arisen from a series of causes including continuous cropping, poor management, and unscientific fertilization. They can be summed up in 9 words: "yellow leaves, dry tips, dead seedlings, low yield." The author now introduces to the broad ranks of agricultural technology extension workers and garlic growers the causes of the two most headache-inducing problems that have appeared in garlic cultivation in recent years. Problem one: the garlic looks normal before winter, with a few yellow leaves and dry tips, but after green-up the garlic seedlings turn severely yellow.

Common Problems in Garlic Cultivation and Their Solutions
Problems in Garlic Production and Countermeasures. Yongnian County is the only high-quality garlic production and export base in our province, with a planting area of 180,000 mu and an annual output of more than 100 million kg each of garlic scapes and garlic bulbs. In recent years, due to many years of continuous cropping, long-term asexual reproduction, and improper planting and management measures, the varieties have become severely degraded, pests and diseases have become serious, and yields have stagnated. To this end, we conducted a systematic investigation. At present, the main problems in garlic production in Yongnian County are as follows: severe variety degradation leading to variety degradation

What problems exist in the process of chicken immunization and medication?
With the development of the broiler farming industry, many farmers regard raising broilers as a way to get rich, but the following two major problems still exist in raising them. (1) Blindly copying outdated immunization programs: many chicken farmers immunize only once with Newcastle disease strain IV vaccine and do not immunize with any other vaccine until sale; some chicken farmers have infectious bursal disease of chickens in every flock, and the yolk fluid used for therapeutic injection contains Newcastle disease antibodies, thereby interfering with the immune effect of the Newcastle disease vaccine; in infectious bronchitis epidemic areas, absolutely
