Storage Methods and Technical Key Points for Peaches, Plums, and Apricots
(1) Room-temperature storage: Peaches are not suitable for room-temperature storage, but due to the needs of transportation and shelf-life preservation, certain measures can be taken to extend the room-temperature freshness life of peaches. 1. Calcium treatment: Soak peach fruit in a 0.2%-1.5% CaCl2 solution for 2 min or vacuum-soak for several minutes, drain the liquid, and leave bare indoors; for mid- and late-maturing cultivars this can improve storability. 2. Heat treatment: Soak fruit in constant-temperature water at 52°C for 2 min, or hold in steam at 54°C for 15 min, which can

Detailed Explanation of Key Technical Points for Greenhouse Peach Cultivation and Management
I. Early training, early shaping, early fruiting. Because greenhouse peach trees are planted at high density, in order to obtain relatively high early income, shaping and flower bud development must be completed within one year: vigorously promote growth in the early stage for early shaping, then control growth in the later stage to produce more flowers. When shaping, whether using the slender spindle form or the "Y" form, yield must be given top priority. Not only should pinching be done multiple times under the premise of adequate fertilizer and water supply to promote more secondary and tertiary branches, but permanent fruiting must also be considered, that is, the branches being trained should not be tipped so they maintain a certain

What are the key technical points for spring garlic management?
Around Jingzhe (Awakening of Insects), as temperatures rise, Cangshan garlic enters the regreening growth stage; around the Spring Equinox, it reaches the rotting-mother stage (also called the mother-returning stage). Due to the continuous low-temperature and drought weather from last winter to this spring, garlic growth has been affected, the seedling condition is poor, and there are more garlic fields with weak seedlings, so management must be strengthened. I. Regreening stage management. Before and after regreening, spray once with a plant growth regulator or amino acid foliar fertilizer to enhance stress resistance and prevent damage to garlic from late spring cold. After the Spring Equinox, garlic is in the rotting-mother stage, during which garlic maggots are prone to occur, so pay attention to spraying pesticide to control seed

Detailed Explanation of Key Technical Points for Early Spring Management of Garlic
Spring field management of garlic mainly refers to the management from after the spring temperature rises until the harvest period. This period is exactly when the garlic bulb expands, and it is also a period when diseases and pests occur frequently. Therefore, doing a good job of management during this period is of great significance for a bumper harvest of garlic. 1. Fertilizer and water management: The application of fertilizer should grasp the principle of supplementing vigorous growth and promoting weak growth. At the same time, irrigate well with the "two waters," namely the green-returning water and the bulb-expanding water. Generally, after garlic returns to green, plots with vigorous growth should be given little or no fertilizer; for plots with yellowing seedlings and weak growth, combined with watering, in

Garlic Storage and Fresh-Keeping Methods and Key Technical Points
Storage of garlic sprouts, garlic scapes and fresh garlic bulbs ① Ice cellar storage: Choose a shaded, sealed room or basement as the cellar. The cellar floor should have a drainage ditch leading outside, spread a 0.8 m thick layer of ice on the floor, and build ice 0.5 m thick against the walls, up to near the roof. Tie garlic sprouts or garlic scapes into bundles of 1 kg, put them into plastic film bags with 15 kg per bag, tie the outside with rope and stack them in the cellar, filling each layer with ice fragments, stacking until about 2 m from the roof, then seal with a layer of ice on top, and spread a 1 m layer of rice husks over it to seal tightly and prevent the ice from melting. This allows garlic to be stored for more than half a year.

How to manage garlic before winter? These technical points must be mastered
1. Topdressing. Garlic has a high fertilizer demand. In addition to applying sufficient base fertilizer, at the 3-leaf stage, fertilizer must be applied once, with 2000-2500 kg of diluted manure water per mu, or 20-25 kg of ammonium bicarbonate mixed with 2000-2500 kg of water for drenching. When applying chemical fertilizer, it must not directly touch the garlic leaves to avoid burning. 2. Intertillage and hilling. Combined with topdressing, carry out intertillage and hilling once, banking fine soil from between the rows up to the base of the garlic seedlings, which can both prevent fertilizer volatilization and preserve soil moisture and prevent freezing. 3. Drought prevention. Garlic is afraid of drought, and drought will affect

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

Key Technical Points and Detailed Methods for Cellar Storage of Sweet Potatoes
1. Timely harvest and careful selection of seed potatoes. In our area, sweet potatoes are generally harvested in late October, around the time of Frost's Descent. Harvesting begins when the soil temperature reaches 15°C and is completed at 2°C. Harvest on a sunny morning to facilitate moisture reduction, and when putting them into the cellar, select potato tubers free from disease, injury, freezing or flooding damage. 2. Cellar treatment. Whether new or old, all cellars must be sterilized and disinfected. Lime water or a 500-fold solution of carbendazim may be sprayed on the cellar walls, or a 1% copper sulfate solution or 50-fold formaldehyde solution may be used for sealed fumigation. 3. Chemical
