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

Scraping pear tree bark in winter is the key to growing good pears
The farming proverb says: "If you want to eat good pears, scrape the bark in winter." In the cold winter season, scraping off the old bark of pear trees that have already borne fruit can effectively eliminate fungal spores such as pear scab, ring rot, anthracnose, and pear rust that remain inside and outside the old cracked bark of pear trees, as well as the eggs of various pear tree pests such as the pear psyllid, aphids, fruit borers, and scale insects, ensuring robust production of pear trees with high quality, high yield, and high returns. Scraping must be thorough When scraping pear tree bark, you must remove the old cracked bark, rot disease, pear scab, ring rot, anthracnose, scale insects, pear psyllids, aphids,

When should honeysuckle be newly planted? Autumn and winter are the right time
Honeysuckle can be planted in two seasons, spring, winter or late autumn, that is, between November and late March of the following year, but late autumn or early winter planting is best. To newly plant honeysuckle, the first step is to choose good land. Honeysuckle is not strict about soil and moisture conditions, and can resist drought, waterlogging and poor soil, but as a highly efficient medicinal plant, and with flower high yield as the management goal, it must be managed intensively. Research shows that honeysuckle likes sunlight and cannot tolerate shade, so sunny sandy loam with relatively deep soil layers, fertile and loose soil, good aeration and drainage, and a slope of 15

Intercropping Cultivation Techniques for Licorice in Land Returned from Farmland to Forest
Intercropping licorice in land returned from farmland to forest can both conserve soil and water and increase economic returns, achieving the goal of using the land to support the forest and the forest to support the land, and realizing a "win-win" for both the economy and ecology. Since 2002, Regiment 137 has conducted cultivation trials of intercropping licorice in land returned from farmland. After several years of experimentation and exploration, breakthrough progress has been made. 1. Land selection: Select sandy loam plots of land returned from farmland to forest with relatively low salinity and alkalinity, relatively few field weeds, and good drainage for intercropping licorice. The main tree species planted in the sowing area is wolfberry seedlings; the planting pattern is furrow planting

How to do intertillage and weeding for licorice? Practical methods and technical key points
Licorice is suitable for growing on idle beach and vacant land where crops cannot be planted, and such land tends to have many weeds as long as there is water, and the success or failure of planting and the level of yield are all related to weeding. When there are many weeds, the utilization rate of water and fertilizer by licorice is low, and the yield naturally decreases. For licorice fields planted in large fields, weeding should be carried out by combining manual weeding and chemical herbicide weeding. That is, in the year of planting, manual weeding is mainly used; starting from the second year, for plots with many weeds, select appropriate herbicides in June to July for chemical weeding, hoe and till once before the rainy season, and till once again after autumn.

Key Techniques for High-Efficiency Cultivation of Soybean Intercropped with Melon
Soybean intercropped with melon at a 4:2 ratio, with Chinese cabbage replanted as the following crop after melon harvest, achieves three harvests from one field and an income of more than 15,000 yuan per hectare, making it a new high-yield and high-efficiency planting model. 1. Selecting new varieties 1.1 For the soybean variety, select Jinta soybean, which has strong branching and super-high yield. Jinta soybean has 6 outstanding characteristics: 1) Strong growth vigor. Jinta soybean has a plant height of 70-80 cm, thick and sturdy stems, and high resistance to lodging; 2) Strong branching ability. A single plant has 8-10 branches, with a maximum of 16 branches. The branches grow upward, and the plant takes on a fan shape without breaking branches, overcoming the tendency of strongly branching soybeans to break branches, resulting in an ideal plant type; 3) Dense pod setting. A single plant sets 200-250 pods, with a maximum of 400 pods. The pods are so dense that the stems are hidden, 2-3 times that of other soybeans. Most pods are 3-seeded, with a yield of 75-100 g per plant and a maximum of 400 g; 4) Excellent quality. The beans are golden yellow, large and uniform, with a 100-seed weight of 22-25 g and high oil and protein content; 5) Strong stress resistance. The growth period is 120 days and requires an effective accumulated temperature of 2450°C. It is drought-resistant, moisture-tolerant, and salt-alkali tolerant, and prefers fertilizer and water.
