The key "three waterings and three fertilizations" technical points for garlic cultivation
Water and fertilizer management after garlic turns green is the key to a bumper garlic harvest. As the weather warms up, water and fertilizer uptake gradually increases after greening, especially during the bolt-bearing stage and the bulb swelling stage, which are the peak periods of water and fertilizer demand for garlic. Therefore, throughout the entire growth period of garlic, timely watering and topdressing should be carried out according to soil moisture conditions and soil fertility and seedling conditions, with special emphasis on doing well the "three waterings" and "three fertilizations." 1. Water the greening water well and apply the greening fertilizer well. By the Spring Equinox, the garlic seedlings begin to turn green and grow. Because the early spring soil temperature is low, it is best to water the greening water at noon

Three key points for raising fish fry in autumn
Adjust the density and grade the rearing. After the beginning of autumn, choose suitable weather when the temperature is relatively cool, pull a net through the pond to sort the uneven-sized fry, and classify them as large (about 20 cm), medium (about 15 cm), and small (below 15 cm). Large-sized fry can be transferred to larger adult fish ponds with better conditions for mixed culture, while medium and small-sized fry are raised intensively in separate ponds. For stocking density, generally a pond with a water depth of about 15 m is stocked with 3000-5000 fish per mu. Fertilize according to the water condition and feed reasonably. For nursery ponds mainly raising silver carp and bighead carp fry, in addition to

To achieve high yield and high efficiency in fisheries, these three measures need to be implemented well
To achieve high yield and high efficiency in fisheries, efforts should be actively made to optimize the ecological conditions for aquaculture and strengthen the construction of supporting pond facilities. Specifically, this can be done from the following three aspects. 1. Implement the renovation of old ponds. The old pond renovation project should follow the requirements of "ecology, circulation, health, and intensification" and carry out major engineering construction such as "desilting and deepening, pond shape transformation, pond embankment slope protection, pond ridge widening and tidying, and improvement of supporting water, electricity, and road facilities," with particular emphasis on removing the thick layer of sludge at the bottom of the pond so that the bottom sediment is reduced to about 20 cm. Through desilting

How to Increase Gastrodia elata Yield? The Three-Switch Measures Are Key
Gastrodia elata is a fine medicinal herb and has been selling well in the market in recent years. The farmers of Chalu Village, Baoshan Town, Fengcheng City, Liaoning Province, regard developing Gastrodia elata production as an important path to wealth; more than 40 households in the village grow Gastrodia elata and earn considerable income every year. Li Jingrong, a retired cadre of the village, has grown Gastrodia elata for 14 consecutive years and accumulated rich experience. He found that the yield of artificially cultivated Gastrodia elata tends to decline year by year. There are mainly 3 reasons: first, because self-bred and self-propagated tuber seeds are used year after year, the degeneration is severe; second, because self-bred and self-propagated fungal strains are used year after year,

Three things to note when cultivating oyster mushrooms in winter
Mushroom yard selection The ideal site suitable for winter cultivation is a mushroom yard with warming and insulation conditions, such as an indoor mushroom house equipped with warming conditions, a warmer underground mushroom yard, and a raised-bed mushroom yard using plastic greenhouse cultivation, etc. The temperature of this type of mushroom yard can be controlled above normal temperature, which is beneficial to mycelial growth and can also promote earlier fruiting. Usually, for early winter cultivation, an outdoor mushroom yard can be chosen; for late winter cultivation, an indoor mushroom house should be chosen. Strain selection Winter-cultivated oyster mushrooms can be divided into two types according to the fruiting period arrangement: winter cultivation with winter fruiting and winter cultivation with spring fruiting. For the former, low-temperature type varieties

There is a knack to processing dried lilies, and the three observations and three determinations are key
In our province, lilies are mainly sold as dried lilies to coastal areas, and in recent years they have consistently sold well. In particular, large, plump, and pure white high-quality dried lilies are in great demand and fetch high prices. Whether dried lilies are high quality or not, processing is a key step. Some farmers report that their fresh lilies are of good quality, but after processing into dried lilies they become second-grade products, or even inferior products, showing non-white color, thin dried slices, and incomplete slices, and the market price is greatly reduced. This is mainly caused by improper processing. In the lily production bases of Daping, Leijia'ao, Shawan, and other places in Niangxi Town, Xinshao County, lilies are planted year-round.

How to Store and Preserve Fresh Peaches? Introduction to Three Practical Methods
Cold storage. Peaches are prone to chilling injury during low-temperature storage, and there is a risk of freezing at -1°C. Therefore, the suitable storage temperature for peaches is 0°C, and the suitable relative humidity is 90%-95%. Under these storage conditions, peaches can be stored for 3-4 weeks or longer. However, when peaches are stored at low temperatures for a long time, the flavor gradually becomes bland. Long-term low-temperature cold storage can cause chilling injury to the peaches, with the flesh turning brown. In particular, when the peaches are moved to a high-temperature environment for ripening, the flesh becomes dry, mealy, and soft, and the flesh around the pit turns noticeably brown. In the cold storage

How to store garlic? Three simple and practical methods to teach you
Garlic belongs to the Amaryllidaceae family (allium genus) and is a bulb vegetable of the onion-garlic category. By color, it is divided into white-skin garlic and purple-skin garlic. Garlic is cold-tolerant; it can be sown from February to April in early spring and harvested from June to July; when sown in autumn and overwintered in the open field, it is harvested from May to June the following year. After storage, it can be supplied to the market year-round. Storage characteristics: when the garlic scapes have been harvested for about 20 days, and about 1/2 or 2/3 of the leaves have turned yellow and the bulbs are fully swollen, this is the suitable harvest period for garlic bulbs. Irrigation should be stopped 3 to 5 days before harvest to reduce soil moisture and improve bulb quality and storability. Garlic has an obvious physiological

Three Major Types of Phytotoxicity to Guard Against in Cotton Cultivation
Diagnosis and identification of phytotoxicity from insecticides and fungicides. The severity of phytotoxicity from insecticides and fungicides depends not only on the cotton variety, growth stage and morphological characteristics, but also on the type of pesticide, as the symptoms of damage differ for each. For example, dichlorvos has an extremely strong vaporizing effect; spraying twice with a 1000-fold solution can scorch cotton leaves dry. After phytotoxicity from lime sulfur mixture, the leaves and boll husks of the cotton plant develop scorched patches, and the leaves soon dry up and drop off. Lime sulfur mixture is a strongly alkaline pesticide; Bordeaux mixture can only be used 7 to 10 days after its application. If lime sulfur mixture is sprayed within 1 to 2 months after spraying Bordeaux mixture, the cotton leaves will develop black copper sulfide deposits, causing phytotoxicity. In short, when using insecticides and fungicides on cotton, a certain interval should be maintained between successive applications of several pesticides (especially inorganic pesticides), to prevent phytotoxicity caused by reactions between pesticides with different modes of action. In addition, the severity of cotton phytotoxicity is also affected by the environment; for example, when pesticides are sprayed under high temperature, the large amount of water evaporation caused by the heat increases the pesticide concentration, causing spots, yellowing and curling of cotton leaves, and even scorching and death.
