Mixed farming of turtles and earthworms in the same pond yields high economic returns
Under micro-flowing water conditions, amphibious turtles and aquatic earthworms are co-cultured in one pond, with the aquatic earthworms serving as the main feed or supplementary feed for the turtles. This can make the turtles strong and healthy, grow faster, shorten the breeding cycle, reduce feeding costs, and more than double economic returns. Moreover, throughout the entire rearing process, contamination of the product by hormone drugs is avoided, meeting the basic requirements for pollution-free food and making it more popular with consumers. The main technical points are introduced as follows: 1. Pond construction: choose a site with abundant water sources and good water quality

Semi-underground three-dimensional cultivation of oyster mushrooms yields high output and good returns
Semi-underground three-dimensional bed-frame cultivation of oyster mushrooms is a new approach explored in recent years to achieve high yields and improve economic returns. According to trials, on an area of 20 sq m, with 2000 kg of substrate, the annual output of oyster mushrooms is about 2500 kg, with a biological efficiency of over 120%. The key technical points are as follows: 1. Building the greenhouse: first dig a pit 1.8 m to 2 m deep and 4 m to 5 m wide, with the length determined as needed, and place the three-dimensional bed frames inside. On top, use bamboo poles and plastic film to build an arched shed, pack the surrounding edges firmly with soil, and cover with straw mats. Leave ventilation openings of about 30 square cm on all four sides, east, west, north and south, and build a small door on the west side for workers to enter and exit.

Scientific and technological leadership brings high returns in silver carp farming
Grow-out fish (market-size commercial fish) farming is the ultimate goal and purpose of fish farming. In recent years, although special aquatic product farming has become "hot" across the country, the traditional farming and consumption of silver carp and bighead carp remain bulk commodities, and the economic returns are still considerable. They have the advantages of small investment, quick results, easy operation, abundant seed sources, and mature production, and are very popular among fishermen. The production process and technical key points mainly use the intensive culture method of "water, seed, feed, density, polyculture, rotation, prevention, and management." 1. Pond conditions: area 0.3-1.4 hectares, clay or loam bottom soil is preferable

Keeping mountain bees brings high returns and is a good path to increasing income and becoming better off
The mountain bee is a wild economic insect. The honey it makes from the nectar of the many flowers in nature is a fine grade of honey, and its market price can reach 30-40 yuan per kg. Generally, one bucket of mountain bees can yield about 25 kg of honey per year. If the colony is strong, the nectar source is good and the climate is suitable, each colony can produce 40-50 kg of honey. Right now is the peak period for mountain bee colony division, and bringing mountain bees home to raise them is a good project with low investment and quick results. Making and placing the bee bucket. The bee bucket is made up of a bottom bucket, an extension bucket, a bucket bottom and a bucket cap (lid)

High returns from the grid-pool fish-lotus polyculture model
The grid-pool fish-lotus polyculture technique involves partitioning a hardened lotus pool with roof tiles, hard boards and the like into small grids of 2-4 sq m each, planting lotus within the grids, yielding an average of 0.5 wan kg of lotus and 400-450 kg of fish per mu of water surface, with a net return of over 10,000 yuan per mu. This technique can make use of waste pits, wasteland, river beach land and scattered corner plots to build grid-pool fish-lotus polyculture systems; it features small investment, low cost, quick returns and high benefits, is suitable for vigorous development by countless rural households, and has very broad prospects for extension.

Master the Three Earlies and Three Skills for Spring Potato Planting to Achieve High Returns
Three Earlies: Choose early-maturing varieties. Practice has proven that selecting high-yielding, high-quality, virus-free potato varieties with a growth period within 70 days (from emergence to harvest) is the key to achieving high, stable yields and quality in spring-planted potatoes. Currently ideal varieties include Holland No. 7, Holland No. 15, Zhengshu No. 6, etc. Start sprouting early. Using a sunny cold frame before planting to pre-sprout can make potatoes emerge early and uniformly, with complete and strong seedlings, promoting early plant development and early tuber formation - this is an important yield-increasing measure. The key points of sprouting technique are: before planting

Growing button mushrooms (Agaricus bisporus) in winter-fallow rice fields delivers good returns
In 2004, our county carried out cultivation demonstrations of growing button mushrooms (Agaricus bisporus) in winter-fallow rice fields across 16 townships. After the late rice harvest, rice straw and other materials were used as the main raw materials and composted and fermented into growing substrate, making use of the winter temperature and light resources and the idle winter season of the rice fields; open-field cultivation of button mushrooms achieved notable returns. Chen Yeru, a farmer at the Lixian Institute of Agricultural Sciences, is a button mushroom cultivation demonstration household, with a family of 4 people and 2 laborers, and had never previously cultivated edible fungi. After technical training at the Lixian Edible Fungi Research Institute, he set up on his own contracted field

Growing potatoes in idle winter fields yields good returns
1. Choose good field plots and sow at the right time. Choose double-cropping rice areas below 100 m altitude, with little or no frost in winter and an average annual temperature above 19°C, requiring paddy fields with deep topsoil, loose texture, medium-to-upper fertility, and convenient drainage and irrigation; at the same time, arrange the sowing period reasonably. After the double late rice is harvested in mid-November, immediately plow deep and sun-bleach the soil, sow in early to mid-December, and harvest from late March to early April the following year. 2. Prepare the land finely and make deep furrows and high ridges. Potatoes grown in paddy fields in winter are most afraid of waterlogging, so fine land preparation should be advocated, with deep plowing and high-ridge cultivation, and planting
