Key Technical Points for Mechanized Micro-Pot Seedling Raising of Cotton
Traditional nutrient pot seedling raising methods have drawbacks such as high labor demand, complex seedbed management and high labor intensity during transplanting. The mechanized micro-pot seedling raising technology for cotton, developed by the Institute of Industrial Crops of the Jiangsu Academy of Agricultural Sciences and the Jiangsu Agricultural Technology Extension Center, breaks through the long-standing traditional model of cotton seedling raising relying on manual work and achieves the goal of saving labor and effort in cotton seedling raising. At present, the mechanized micro-pot seedling raising technology is at the experimental demonstration stage and has not yet been promoted and applied on a large scale, and farmers do not sufficiently understand and master the technology. For this reason, our newspaper's reporter interviewed Associate Researcher Zhang Peitong, a cotton cultivation research expert at the Institute of Industrial Crops of the Jiangsu Academy of Agricultural Sciences, about the advantages and disadvantages and detailed technical procedures of mechanized micro-pot seedling raising.

Key Techniques for Raising Southern Yew (Taxus wallichiana var. mairei) Seedlings from Seed
The southern yew (Taxus wallichiana var. mairei) combines medicinal, timber and ornamental value, and has high development and utilization value. Because its seed coat has poor permeability and the dormancy period is long, propagation from seed is difficult. But as long as you grasp the biological characteristics of the southern yew and strictly follow the technical procedures, seedling raising is certain to succeed. The specific operations are as follows: 1. Nursery site selection and fertilization The nursery site should preferably be a paddy field with deep soil, loose structure, rich organic matter, good drainage and no exposure to afternoon sun (it must be paddy field soil from that year's harvest). After harvesting the mid-to-late rice, once the soil is dry, plow deeply once

Detailed Explanation of Seed Seedling-Raising Techniques for Taxus yunnanensis
Taxus yunnanensis Cheng et L. K. Fu is a rare evergreen tree under first-class national protection, suited to the high mountain zones of northwestern Yunnan at 2000-3500 m. Because its branches, leaves, bark and roots can all yield the expensive anti-cancer drug taxol, the Taxus market has boomed in recent years and prices have soared all the way up. World annual demand for taxol exceeds 4800 kg, while actual annual production is only about 250 kg. In China, Beijing, Shanghai, Liaoning, Yunnan and Sichuan

Key Technical Points for Raising and Managing the White-Banded Snake
Snake farming is a path to prosperity with low investment, high returns, and quick results. At present, domestic snake farming is mainly focused on the medicinal white-banded snake. I. Site Setup for Domestic White-Banded Snake Farming 1. Indoor rearing. The walls and wall foundations of the snake house must be paved with cement or asphalt to prevent rats from burrowing. The door must be seamless, the walls must be painted smooth, and the wall height must be above 2 m to prevent the snakes from escaping the snake house and injuring people outside. A water dispenser should be set up indoors to continuously supply clean drinking water, which helps the snakes shed their skin. 2. Outdoor rearing. This allows more

Detailed Explanation of Techniques for Raising Fish Fry in Reservoir Cages Without Feeding
In reservoirs with fertile water quality, using cages to raise silver carp and bighead carp fry without feeding is not only practical and feasible, but also has advantages such as not occupying fry ponds, not spending on fish feed, and low cost. Without feeding, raising one silver carp or bighead carp fry of about 13cm in a cage in a reservoir costs less than 0.10 yuan, while raising one fry of the same size in a pond costs more than 0.10 yuan; converted per mu, the yield is about 150,000 fry/mu or more, which is 30-40 times that of internal ponds. Therefore, reservoir cage culture without feeding

Do chickens need vitamin supplements during raising?
Of course they do. The vitamins in feed are far from sufficient, and some are destroyed during processing. Although the required amount of vitamins is very small, their role is enormous. They not only participate in regulating metabolism in the body, but are also usually components of certain enzymes. Vitamins are divided into fat-soluble vitamins and water-soluble vitamins according to whether they dissolve in water. Fat-soluble vitamins refer to vitamins that do not dissolve in water but only in fat, including vitamin A, vitamin D, vitamin E, and vitamin K. Modern science

Schisandra chinensis asexual propagation and seedling raising: Rootstock method for green-branch cleft grafting
For the cultivation of rootstocks for green-branch cleft grafting, refer to open-field direct seeding for seedling raising. If the rootstocks are not dug out before winter arrives, pruning must be carried out before the ground freezes. Leave 3 to 4 buds on each rootstock and cut at about 5 cm, then water thoroughly with winter-protection water to prevent freeze damage and drying out. If the rootstock seedlings are to be planted out the following year, the seedlings can be dug out and stored in cellars or trenches, which is more beneficial for rootstock seedling management. When planting out the following year, they also need to be cut back to 3 to 4 buds to establish the trunk. Rootstock seedlings that overwinter in place should be irrigated promptly after the ground thaws the following year and given a topdressing of quick-acting nitrogen fertilizer to promote new shoot growth. Keep 1 to

Detailed Explanation of the Key Points of Cotton Water-Floating Seedling Raising Technology
"Cotton water-floating seedling raising technology" is a new cotton planting technology developed by agricultural experts in Hunan Province. This technology uses a porous polyethylene foam seedling tray as the carrier, with a mixed substrate as support, and places the seedling tray carrying cotton seeds into a nutrient solution water bed for cultivation. It has notable effects in saving seeds, saving labor, increasing yield, and improving efficiency. Compared with conventional nutrient bowl seedling raising and transplanting of cotton, it saves more than 40% of seed quantity, and reduces labor by about 10 workdays per mu for seedling raising and transplanting. The cotton seedlings have well-developed root systems, a low degree of lignification, and are soft and elastic, not easily broken, with strong vitality

Hardwood cleft grafting method for asexual propagation and seedling raising of Schisandra chinensis
After leaf fall and before bud break, collect 1-year-old branches as scions; before the ground freezes, lift 1- to 2-year-old seedling stock as rootstock, and store them at low temperature for cleft grafting during the next year's bud break period (or graft in place without lifting the seedlings). Before grafting, soak the scions and rootstocks in clean water for 12 hours. Cut off the bud-bearing portion at the hypocotyl of the rootstock. For scions, choose fully mature branches with a diameter greater than 0.4 cm, cut them to a length of 4-5 cm, keep 1 bud eye, leave 1.5 cm above the bud, and keep about 3 cm below the bud; use a grafting knife to cut down on both sides of the scion bud eye
