How to store scallions for a long time? Practical storage techniques shared
Optimal storage temperature: 0°C Relative humidity: above 95%RH Scallions, like leafy vegetables in general, are suited to storage in a low-temperature, high-humidity environment. Above freezing, the lower the storage temperature the better (around 0°C), and the relative humidity should ideally be 98-100%RH. Therefore, they can be placed in a perforated plastic bag. Trimming the root ends of scallions before bundling can avoid bringing large amounts of waste to market. If hygiene is maintained during trimming to prevent the entry of pathogenic bacteria, the difference in storage life between trimming and not trimming is small. Commercial sellers may choose

Detailed Explanation of Practical Key Techniques for Schisandra Seedling Cultivation
Seed treatment: In early September, select plants that show early fruit coloring, tightly arranged berries, and long spikes with large berries, as seed collection trees, and collect mature berries from the middle and lower parts of Schisandra as seeds. Soak in clean water for 2-3 days, then rub off the pulp, float away the shriveled seeds, scoop out the seeds and drain the water, place in a ventilated place to dry in the shade, soak the seeds in early January, after absorbing water for 48 hours, scoop them out and air-dry, mix with snow at a ratio of 1:3 and stir thoroughly and evenly, then place in a shaded outdoor area for frozen storage. Calculate the sowing period well, take the seeds out half a month before sowing

These practical techniques help late-sown wheat achieve high yields
Because late-sown wheat (wheat sown after mid-October, generally called late-sown wheat) is sown late, it is difficult to achieve full, strong and uniform seedlings, and thus difficult to obtain high yields. However, with proper management, a high yield is entirely possible. 1 Apply sufficient base fertilizer. Late-sown wheat needs 10-15 days from sowing to emergence, which shortens the pre-winter growth period and causes the seedlings to grow in the soil for too long and become weak. Late-sown wheat must be given sufficient base fertilizer, with 3500 kg of high-quality farmyard manure, 40-45 kg of ammonium sulfate, 50 kg of superphosphate and 10 kg of potash fertilizer per mu

How to Store and Preserve Peaches, Plums and Apricots for Freshness? A Detailed Guide to Practical Techniques
Peach, plum and apricot (including cherry) fruits all contain a hard stone and belong to the stone fruit category, sharing common characteristics in fruit development and postharvest physiology. It is precisely because the fruit contains a hard stone that a double-S growth curve appears during growth. Peach, plum and apricot fruits have high respiration intensity; all exhibit a respiration peak, so they all belong to the climacteric type of fruit, which determines that they share basically similar storage, transport and freshness-preservation technical measures. However, as tree species and cultivars differ, the storage, transport and freshness-preservation techniques adopted also differ. Peaches and plums are generally divided into early,

How to control subsurface pests in upland rice? A full breakdown of practical techniques
In recent years, with the application and promotion of dry-raised transplanting techniques, upland rice cultivation in Gejiu City has become a new highlight of economic growth in mountainous rural areas. How to do a good job in controlling subsurface pests is an important technical measure for developing upland rice production and ensuring increased yield and income. The common subsurface pests of upland rice mainly include white grubs (the larvae of scarab beetles), wireworms (the larvae of click beetles), mole crickets, and cutworms (cut worms). These pests live in the soil during their damaging period, feeding on seeds, young sprouts, roots and stems, causing missing plants, gaps in rows, or

How to carve and strip trunk bonsai? Three practical techniques
The trunks of trunk bonsai mostly use the image of being ancient, old, diseased, and disabled to show their "vigorous and sturdy character" that has endured the vicissitudes of time, while some bonsai trees show the characteristics of being young, tender, smooth, and sleek. The carving and stripping technique for trunk bonsai is precisely based on the conditions of the trunk itself, through artificial artistic reconstruction, to make the trunk image conform to the requirements of bonsai artistic modeling and achieve the purpose of enriching the varied texture layers of the trunk. Now let us introduce three techniques of the carving and stripping method. Spiral trunk stripping. Make partial diagonal rotational carving and stripping modeling on the main trunk from bottom to top

Practical Guide to Fresh-keeping and Processing Techniques for Shiitake Mushrooms
1. Drying equipment: Although shiitake drying equipment at home and abroad differs in form, scale and technical level, its principle is basically the same. Generally there are the following models: (1) forced circulation dryer; (2) forced ventilation parallel-flow dryer; (3) heat pump dryer. 2. Drying methods (1) Raw material handling Before drying, trim off the mushroom stalks or stem bases from the freshly picked mushrooms, remove impurities, and process after grading. Mushrooms picked on rainy days or with high moisture content should first be spread out to air-dry so that

How to fertilize Schisandra chinensis? A detailed explanation of practical fertilization techniques
Building a successful Schisandra chinensis orchard makes scientific fertilization the key. Schisandra chinensis is a perennial plant, and after planting it must grow continuously for more than 10 years within a limited nutrient range. As the cultivation years increase, the nutrients in the soil gradually decrease, the underground creeping stems are widely distributed, the growth is vigorous, and nutrient consumption is high. Therefore, rational fertilization is very important for the growth of Schisandra chinensis. The fertilization method and amount should pay attention to the following aspects. In the year Schisandra chinensis is transplanted, the root system is not well developed and the branches are thin and weak. In order to promote the seedlings and strive to bear fruit in the second year, urea can be applied in late May

How to prevent and control excessive vegetative growth in cotton? A detailed guide to practical techniques
At present, cotton has entered the squaring stage, and preventing excessive vegetative growth in cotton must begin now. So-called excessive vegetative growth means the cotton has lost its normal reproductive function, that is, it only flowers without setting bolls, or it flowers heavily but sets few bolls. The causes are first climatic factors, second the blind and random introduction of cotton varieties, and third cultivation methods that do not match climate change. According to records, when the temperature exceeds 35°C, pollen development becomes abnormal and normal pollination cannot occur; while sustained drought intensifies the shedding of squares and bolls. In addition, in mid-August some cotton areas experience

A Detailed Guide to Practical Techniques for Shiitake Mushroom Processing and Fresh-Keeping
When harvesting shiitake mushrooms, place them gently in plastic baskets without squeezing or deforming them, then remove impurities from the fruiting bodies, pick out damaged mushrooms, trim the base of the stems, and sort them according to cap size, thickness and moisture content, arranging them on bamboo blinds or reed mats in a ventilated place. They should be processed promptly; piling them together for a long time will reduce quality. 1. Drying shiitake mushrooms (1) Sun-drying: For mushrooms to be sun-dried, stop spraying water directly on the fruiting bodies 2-3 days before harvest to avoid excessive moisture content in the fresh mushrooms. Harvest promptly when the fruiting bodies are 70-80% mature, the partial veil has just broken, and the cap edges curl inward in the shape of a copper gong. It is best to harvest on a sunny day; after harvest, use stainless steel scissors to trim the stem base, sort according to cap size, thickness and moisture content, spread them gill-side up on reed mats or bamboo blinds, and place them in sunlight to dry. Generally, about 3 days of drying is needed to reach full dryness.
