Sweet potatoes turn into feed, saving costs and increasing efficiency at the same time
1. Tuberous roots: each unit of fresh sweet potato is equivalent to 0.3 corn units. It is an excellent succulent feed and also a very good energy feed. All kinds of livestock like to eat it, and it is most suitable for feeding meat pigs. The method is to boil it, mix 15-20 kg of cooked sweet potato with 1 kg of concentrated feed (crude protein >= 34%), stir evenly and feed to meat pigs. The effect is the same as a complete compound feed, but the feed cost is much lower than compound feed. Feeding sweet potato alone or feeding it raw has a poor effect. Tuberous roots that are rotten or have black spot disease should be buried deep in a pit, and it is strictly forbidden for humans and livestock to eat them

Key Technical Points and Precautions for Saving Seed of Water Dropwort
Water dropwort reproduces asexually, and its stems are the propagation material. For water cultivation, select seed plants in late November. The selection criteria are: possessing the excellent characteristics of the variety being saved, with moderate plant height, thick and sturdy stems, relatively short internodes, numerous and robust axillary buds, a well-developed root system, and freedom from insects and disease. The selected seed plants are then immediately transplanted into the seed-saving field. The seed-saving field should be chosen in a spot sheltered from the wind and facing the sun, with convenient drainage and irrigation. In mid-October, carry out fine land preparation and apply a thick basal fertilizer. When planting the seed plants, maintain a 1 cm water layer in the field, with both row spacing and plant spacing of 25 cm,

Detailed Explanation of Water Dropwort Seed Saving Methods and Technical Key Points
Select robust mother plants, requiring characteristics such as medium height, thick stems, short internodes, and relatively concentrated tillering. Once the mother plants are selected, transplant them into the seed-saving field immediately after pulling. The water dropwort seed-saving field should be a paddy field that is warm and sunny, easy to drain, and convenient for roguing. Cultivate finely, applying 1 ton of decomposed human and animal manure and 50 kg of plant ash per mu as base fertilizer. In mid-November or late March to early April of the following year, choose warm and sunny weather, pull selected seed plants from the main field, arrange them in clumps of 3-4 stems, and transplant them neatly. After spring planting, the plants that survive grow relatively small, generally

What are the water-saving and drought-tolerant management and care methods for Hokkaido euonymus?
Hokkaido euonymus is an evergreen broadleaf small tree in the Celastraceae family, genus Euonymus. When Euonymus bungeanus is used as rootstock to graft Hokkaido euonymus, the tree has an upright posture and stays evergreen in all four seasons. After winter arrives, the mature fruit splits open to reveal the red aril, with green leaves and red fruit, giving extremely high ornamental value. It is a rare evergreen broadleaf tree in the cold regions of the north. It is not demanding about soil and can grow very well in sandy soil, sandy loam, loam and soil with a soil organic matter content above 0.8%. It adapts to soil with a pH value of 6 to 9 and a total salt content within 2‰. The high graft height is 1 to 1.8 m, and the low graft

The only standard water-saving and drought-resistant rice variety for the southern rice region has been bred in Shanghai
The Shanghai Academy of Agricultural Sciences announced on the 16th that Shanghai agricultural scientists have bred the only upland rice control variety for regional trials in the southern rice region and the first japonica-type upland rice variety in the southern rice region to pass national approval, and have built China's most complete rice drought-resistance identification and evaluation system and germplasm resource platform. Shanghai has become the country's main base for rice water-saving and drought-resistance research. According to Gu Xiaojun, vice president of the Shanghai Academy of Agricultural Sciences, the "Zhonghan No. 3" bred by scientists here is the first upland rice variety in China's southern rice region to pass national approval, and has been

Key Techniques and Detailed Methods for Seed Saving of Angelica sinensis
For raising seedlings and transplanting, seeds of medium maturity produced from flowering in the third year should be used. A single plant, besides the main bud, has many lateral buds. Both the main bud and the lateral buds can bolt, flower and set seed. Flowering branches that bear seeds can also grow from the axils of the main stem. Because the growth periods of the various flowering branches differ, flowering times and seed maturation occur in succession. Therefore, when collecting seeds, one must frequently observe in the field. Looking down from the top of the flowering stem, when the first umbel appears pink, the second umbel appears light red, and the third umbel appears pale yellow, it is time to harvest (generally in early to mid-August). Seeds that are over-mature, after seedling raising

Practical Tips for Saving Feed in Yellow Catfish Farming
Currently, yellow catfish (Pelteobagrus fulvidraco) farming is quite widespread and is a major species for increasing income among fish farmers in many places. However, during the farming process, many farmers, in their one-sided pursuit of output, do not know how to save feed and continuously put excessive feed and fertilizer into the aquaculture water. This not only causes farming costs to rise day by day, but also continuously deteriorates water quality, affecting the growth of yellow catfish and resulting in low farming benefits. How can feed costs be saved in production practice? Strictly remove trash fish and disinfect the pond. Pond disinfection can kill wild trash fish, reduce competitors for food

Six practical methods for cost-saving and efficiency-boosting in edible mushroom cultivation
1. Temperature difference stimulation method: Cover the mushroom bed with film during the day to raise the temperature, and uncover the film in the evening or morning to cool it down. During the early stage of mycelial growth, the relative air humidity should be kept below 70%, and in the later stage at 85%-90%. These measures are conducive to the formation of mushroom buds. 2. Chemical stimulation method: When preparing the substrate, appropriately add phosphates (monopotassium phosphate, superphosphate), sulfates (magnesium sulfate, calcium sulfate) and vitamin B1, etc., which have an obvious yield-increasing effect. In the late stage of mycelial growth, spray 0.1 mg/L

Practical tips for saving feed in yellow catfish farming
Currently, yellow catfish (Pelteobagrus fulvidraco) farming is quite widespread, and it is a major farmed species through which fisher-farmers in many places increase their income. However, during the farming process, many farmers, in their one-sided pursuit of output, do not know how to save feed and continuously put excessive feed and fertilizer into the farming water body, which not only drives up farming costs day by day but also causes the water quality to deteriorate continuously, affecting the growth of yellow catfish and resulting in low farming returns. How can feed costs be saved in production practice? Strictly remove trash, clear the pond and disinfect. Clearing and disinfecting the pond can both kill wild trash fish and reduce

Mushroom fermentation agent helps mushrooms achieve high yield, high quality, and time savings
Using a fermentation aid to make edible mushroom growing substrate allows fast and thorough fermentation, working at both high and low temperatures, greatly shortening the fermentation production time, reducing labor intensity, and lowering production costs. It also has the characteristics of broad-spectrum fermentation and strong adaptability (it can ferment almost all organic matter that needs fermentation, and has relatively loose requirements for environmental conditions), and can be widely used for button mushroom (white mushroom), Agaricus edulis (double-ring mushroom), oyster mushroom (Pleurotus), Hypsizygus marmoreus (small oyster mushroom), straw mushroom (rice-straw mushroom, Chinese mushroom), silver-thread straw mushroom
