How to release seedlings after mulching cotton fields with plastic film? Practical tips to share
In plastic-film-mulched cotton fields, the temperature is high, and seedlings emerge quickly and evenly. It takes 8 days from sowing to emergence, and 3 to 4 days after emergence for full stand. After full stand, if the late frost has passed, holes should be broken to release the seedlings. Releasing seedlings too early means they cannot achieve full stand or complete stand; too late is not good for strong seedlings, and if high temperatures occur, it often causes seedling scorching. For drill sowing, holes should be punched according to plant spacing to release seedlings; for hole sowing, holes should be punched according to seedlings. After breaking the film and releasing seedlings, cover the openings with soil to prevent moisture loss, temperature drop, film lifting by strong wind, and weed growth. When releasing seedlings, grasp the principle of releasing green but not yellow, that is, cotton seedlings with flat and expanded cotyledons can be released; yellow-valve seedlings that have not expanded, if released, are easily dried by wind or killed by sun, and cannot be released through holes.

How to care for water-and-land bonsai? A full analysis of practical tips
Watering: Water-and-land bonsai are planted in very shallow pots, so special attention must be paid to replenishing water in time. To prevent the potting soil from being washed away when watering, it is best to use a fine-nozzle watering can. When the climate is dry, a sprayer can be used to mist the pot surface, the trees and the rocks to keep the moss growing well. Fertilizing: The soil in water-and-land bonsai is relatively little and nutrients are limited, so attention should be paid to fertilizing to keep the trees growing vigorously. Fertilizing is mostly done by spraying diluted organic fertilizer water onto the soil surface. Granular organic compound fertilizer can also be buried in the potting soil. Repotting: The trees in water-and-land bonsai are generally repotted once every 3 to 5 years, mostly

How to Store and Preserve Fresh Peaches? Practical Tips Shared
Fresh peaches have a short storage life and are prone to rotting and spoilage. If the following preservation methods are adopted, the supply period of fresh peaches can be extended and economic benefits improved. 1. Harvest without injury, grade and package. To judge the maturity of peach fruit: first, after the fruit has fully developed, the skin begins to lose its green color, the flesh is slightly firm, and colored varieties have basically reached full color - this is the firm-ripe stage. Second, when the background color of the fruit is green or light green and the fuzz on the fruit surface begins to color - this is the seven-to-eight-tenths ripe stage. Fruit at the firm-ripe stage and the seven-to-eight-tenths ripe stage stores better and tolerates long-distance transport. Because peach maturity is uneven, most

How to water rhododendrons? A few practical tips for you
Watering rhododendrons is a very important task. Because the rhododendron's root system is relatively fine and weak, it fears both waterlogging and drought, and either too dry or too wet conditions are bad for the plant's growth, so special attention must be paid to controlling the amount of water. If there is a lack of water during the leaf-expanding stage, the rhododendron's leaves will turn yellow and curl, and if the dryness is severe, it can even die. If there is a lack of water during flowering, the petals will become soft and shrunken, the flowers will droop, the flower color will be dull, and the flowers may even wither and die. Therefore, watering must be done as appropriate according to conditions such as sunny or rainy weather, dry or humid air, and the moisture content of the potting soil. Watering

How to formulate feed for pigs during lactation? Sharing practical formulation tips
Sows during lactation need large amounts of nutrients to support milk production. At peak lactation, the sow's milking capacity exceeds the nutrients she takes in through feed and the nutrients excreted in milk are greater, so the sow's body condition declines rapidly. Formulating high-quality, high-nutrient-density feed for lactating sows is the best way to resolve this contradiction. Feed Formula 1: Lactation Feed Formula 1 in Table 4-3 avoids as much as possible the use of bulky feeds such as alfalfa and rice hull bran. In the design of lactation feed formulas, unknown nutritional factors appear less important

Treatment Methods and Practical Tips for Fish External Injuries
The fish body surface has a layer of mucus, which serves to protect the body surface from bacterial invasion. When a fish suffers an external injury, it is prone to infection by bacteria or mold, causing secondary diseases. Therefore, when a fish suffers an external injury, it should be treated promptly to avoid infection. During treatment, you can directly apply red mercurochrome to the injured area (avoid applying it to the eyes), or soak the sick fish in a dilute solution of 1 to 2 parts per million of antibiotics (such as tetracycline, furacilin, etc.). You can also apply anti-inflammatory ointment (such as erythromycin ointment, tetracycline ointment) to the injured area.

How to Identify the Quality of Edible Mushroom Spawn? Practical Tips Shared
Edible mushroom spawn, like the seeds of crop vegetables, is the internal factor and foundation for achieving high and stable yields. The quality of the spawn directly affects the yield of edible mushrooms and even determines the success or failure of cultivation. Therefore, identifying and assessing the quality of spawn is very important. 1. Look 1. Check whether there are abnormal spots or patches of red, yellow, black, green, etc. around or on the surface of the substrate in the spawn bottle (bag). If any of the above phenomena exist, it indicates that the spawn has been contaminated by foreign molds (except for varieties that produce pigments, such as shiitake and nameko),
