  • What should be noted when herding ducks in spring?

    Choose good grazing grounds. During spring plowing, in rice-growing areas, ducks can be grazed in green manure fields that have been plowed and are being prepared for transplanting rice seedlings. Such fields contain plenty of natural plant and animal feed, such as grass seeds, grass roots, earthworms, and insects. After the rice seedlings are transplanted, ducks should not be taken into the fields to graze; grazing can resume only after the rice is harvested. Graze carefully. In river network areas, make full use of river channels for grazing. Generally, when taking the ducks out to graze, it is better to go upstream, when the ducks are full of energy and catch more food. In the cold spring season, when windy weather occurs, graze against the wind to prevent the wind from lifting the ducks' feathers and causing them to lose too much body heat. In areas with abundant feed

  • Detailed Explanation of Key Points of Spring Potato Cultivation Techniques

    Potatoes have the characteristics of high yield, early maturity, multiple uses and wide distribution, and in recent years the spring planting area in our region has been expanding year by year. 1. Land preparation. Potatoes prefer sandy loam and loam. Deep plowing and winter watering can be carried out before winter, with 2500-3000 kg of organic fertilizer applied per mu, and the land leveled before sowing with sufficient bottom moisture water. Through the shallow plowing and fertilizing method, 25 kg of potassium sulfate, 25 kg of diammonium phosphate and 15 kg of urea per mu are broadcast on the surface and worked into the soil with a rotary tiller. When ridging, the ridge width is 60 cm, the ridge height is 20-25 cm, and the ridge spacing is 100 cm.

  • How to keep turtles safe through early spring? Key points for turtle care management

    In early spring, turtles have just woken from hibernation and are very weak in activity. In addition, temperatures during this period are unstable, often fluctuating between high and low, making it a critical time for turtle care. So how can you care for turtles well during this period? (1) According to the turtle's physical condition, if heating is needed, raise the water temperature to about 25°C. (2) For feeding, follow the principle of small amounts and high quality. The amount for the first feeding should not be too much; 1% of the turtle's body weight is suitable, and feed twice a week. (3) When changing the water, the temperature difference between the new and old water should not exceed 5°C,

  • What are the key techniques for open-field cultivation of spring potatoes?

    Potatoes are nutritious, high-yielding, easy to store, and have a long market period. They can be used as both a vegetable and a staple food, and are deeply loved by consumers. Open-field cultivation of potatoes in spring is the most common cultivation method, and almost every farming household plants them. To achieve high quality and high yield in open-field spring potatoes, the first step is to select good varieties. Potato seed potatoes must be original seed of varieties such as "Dongnong 303" and "Kexin No. 4" introduced from the north. Do not use self-saved seed, and even more so, do not use local seed that has been planted for many years, has an aging variety, and seriously degraded seed characteristics. "Dongnong 303" and "Kexin No. 4" have shown high quality, high yield, and early maturity after years of

  • Key Techniques for Winter and Spring Cutting Propagation of Carnations

    Carnations are generally propagated by cuttings, carried out in winter and spring, and can be done anytime from December to April of the following year. The lateral buds used as cuttings at this time grow robustly and are of the best quality. At the same time, cuttings taken during this period can control the plants to bloom at New Year's Day and the Spring Festival of the following year. First, the growing medium should be prepared, generally using garden soil mixed with 30%-40% rice husk ash or sandy soil, mixed evenly, then placed in cutting pots or wooden boxes. Cutting must be done in a greenhouse, selecting cuttings from mother plants that are vigorous in growth, uniform in flowering, and have thick, short-jointed branches.

  • The key to a bountiful spring mushroom harvest lies in winter management of the mushroom bed

    After the autumn mushroom harvest is over, if no warming measures are taken and winter mushroom production continues, then the mushroom bed will enter the winter management stage. How well the winter management of the mushroom bed is done has a huge impact on the spring mushroom harvest of the following year. Therefore, the winter management work of the mushroom bed must be done well. The main measures are: do a good job of insulation and ventilation of the mushroom house. In winter, the room temperature of the mushroom house is best kept above 3°C, so that the room does not freeze, to prevent the mycelium from being damaged by frost. In order to maintain this temperature in the mushroom house, before winter arrives, the leaky spots on the four walls of the mushroom house

  • How to manage greenhouse apricots in spring? Focus on management to promote development

    For apricot trees in a winter-warm greenhouse, the fruit development period runs from mid-February to the end of April, and this period is divided into three main development stages. The first stage is the first rapid growth period of the apricot tree and the new shoot growth period, lasting 28-34 days; the second stage is the pit-hardening period, lasting 8-12 days; the third stage is the second rapid growth period of the apricot fruit and the new shoot growth period, lasting 20-30 days. Management work for the first stage: after flowering, apply 0.5 kg of nitrogen fertilizer and 1 kg of phosphorus fertilizer per tree, and within two weeks after flowering spray 0.3% urea once every 7 days. After leaf expansion, spray Yibianjing or Yashijing

  • Key Techniques for Winter-Spring Cutting Propagation of Carnations

    Carnation is an annual or perennial clump-forming herbaceous flower of the genus Dianthus in the family Caryophyllaceae. Its propagation can be carried out by sowing, cuttings, layering, tissue culture and other methods, but cutting propagation is generally the most commonly used, carried out in winter and spring. Generally speaking, carnation cuttings can be taken from December to April of the following year, with January to February being the most suitable; at this time the lateral buds used as cuttings grow vigorously and are of the best quality. At the same time, cuttings taken during this period can control the plants to bloom at New Year's Day and Spring Festival of the following year. The survival rate of cuttings taken in March is also

  • How to prevent spring sheep blindness? These preventive measures must be taken well

    Sheep that eat the roots of the toxic daylily (Hemerocallis minor) will suffer poisoning. The clinical signs are characterized by blindness in both eyes, dilated pupils, bladder paralysis with urine retention, and general paralysis, which people call "blindness disease". In early spring, when pasture grass is scarce between seasons and the daylily is sprouting, grazing sheep often become poisoned after eating it, and generally die after 2 to 4 days. Mildly poisoned animals can recover, but those with blindness in both eyes and dilated pupils cannot recover. For this disease, there is currently no effective antidote, and the main approach is to carry out prevention well.
