Winter pond fish farming has many benefits, and winter is the right time to farm
Guangdong Province is located in the tropical and subtropical zones, with abundant water and heat resources. Taking the Guangzhou area as an example, the annual average temperature is above 23°C, and even in the coldest month, January, the average temperature still reaches around 13°C. This natural advantage is very favorable for carrying out "winter farming" of pond fish. Practice in various places has proven that "winter farming" of pond fish has many benefits: First, when the weather is cold and the water temperature is lower, the organic matter and fertilizer in the pond decompose slowly, the pond water is fresh, and oxygen is sufficient, which is conducive to rapid growth and easy fattening of pond fish; Second, because the weather is colder, bacteria and parasites in the pond are not easy to reproduce and grow, so pond fish

Yellowing of winter wheat seedlings: classified control is key
When wheat seedlings turn yellow because the sowing soil moisture is poor, soil water is insufficient, emergence is uneven, and growth and development are poor, irrigation should be suited to the soil and applied rationally. When seedlings turn yellow due to a lack of fertilizer nutrients, nitrogen, phosphorus, and potassium fertilizers must be applied promptly; apply 15 kg of urea per mu mixed with dilute manure water, and at the same time use 0.5 kg of monopotassium phosphate per mu, diluted with water and sprayed on the leaves 1 to 2 times, to prompt the wheat seedlings to regain color in time. For wheat seedlings turning yellow due to heavy, compacted saline-alkali land, use 20 to 30 kg of superphosphate per mu

Winter Snow Honey Peach is a rare new extremely late-ripening peach variety
Winter Snow Honey Peach is a rare new extremely late-ripening peach variety selected and bred in 1986 from Qingzhou Honey Peach. With its unique advantages, it has attracted widespread attention and welcome from numerous fruit tree experts and the vast number of fruit growers. This peach is currently the valuable variety resource among late-ripening peaches in China with the latest ripening period, the strongest storage tolerance, and the best quality, and it has broad development prospects. 1. Extremely late ripening period. It ripens in early to mid-November, that is, between the Beginning of Winter and Light Snow. The fruit can tolerate slight frost. As long as frost damage does not occur, it can remain hanging on the branches without falling or rotting, and it is currently

Rose Winter Cutting Methods and Technical Key Points
From mid-October to early November, in conjunction with winter pruning of roses, select branches with evenly spaced internodes and plump dormant buds, remove the leaves, and cut them into 10 cm long cuttings (about 3 nodes), with the upper end cut flat and sealed with paint, and the lower end cut at an angle for later use. 2. Preparation of seedbed and nutrient bags: Choose a plot that is sheltered from the wind, faces the sun, has flat terrain, and loose soil, and make a seedbed 1 m wide, 5-6 m long, and 20-30 cm deep. Mix fully decomposed nutrient soil and fine sandy soil in equal halves to make moist nutrient soil, and treat with zinc

Key Points for Winter Production Techniques of Cut Rose in Northern China
The off-season production of roses requires the flowering period to be from September to April of the following year. Therefore, management must include both summer control of top growth and promotion of root development, as well as winter greenhouse management. Varieties with strong adaptability can be selected, such as Xianyi Shangjiao, Sabensha, etc. 1. Fertilization and density requirements: Before planting roses, sufficient base fertilizer should be applied. Generally, 5 cubic meters of farmyard manure and 2 cubic meters of chicken manure per greenhouse, mix well and plow into the ground, then rake level. Make beds in a north-south direction, bed width 1 m, length limited by the greenhouse width. Each bed can plant two rows, row spacing 0.4 m, plant spacing 0.3 m, generally 7-8 plants per sq m is suitable.

Key Techniques for High-Yield Winter Cultivation of Cut Rose
Winter is the season when cut roses are in relatively short supply in northern regions, and cut flower prices are also higher in this season. Therefore, increasing the winter yield of cut roses is extremely important for increasing the annual income from cut roses. A set of high-yield techniques for cut roses in solar greenhouses is introduced here: 1. Ensure greenhouse temperature and soil temperature. First, adopt a reasonable greenhouse structure to ensure the greenhouse absorbs solar energy to the maximum extent, raise the indoor temperature, and keep the daytime room temperature at around 25°C, with the maximum not exceeding 28°C. Second, use

Key Techniques for High-Yield Winter Cultivation of Cut Roses
Winter is the season when cut roses are in short supply in northern regions, and cut flower prices are also higher during this season. The key technical points for high-yield winter cultivation of cut roses in solar greenhouses are briefly introduced as follows: 1. Adopt various insulation measures to raise the greenhouse air temperature and soil temperature. First, a reasonable greenhouse structure should be used to ensure the greenhouse can absorb solar energy to the maximum extent, raise the indoor temperature, and maintain the daytime room temperature at around 25°C, with a maximum not exceeding 28°C. Second, cover the greenhouse with cattail mats, straw mats, insulation quilts or paper quilts to reduce heat loss.

Grain-mushroom intercropping planting model boosts yield and income
Corn-oyster mushroom intercropping uses a 2:1 intercropping cultivation form, improving field ventilation and light penetration; the oyster mushroom production requires more watering, which is very beneficial to corn growth. The spent mushroom substrate still contains relatively rich organic nutrients and can be turned into the soil as high-quality farmyard manure to build soil fertility. Intercropped corn can be sown in late April; on the basis of early-spring plowing and harrowing, spread farmyard manure, form ridges 60 cm wide, with plant spacing smaller than that of pure corn stands, and add the corn plants from the mushroom rows to the rows on both sides respectively, ensuring

Key Points of Winter Pruning Techniques for Schisandra chinensis and Magnolia biondii
I. Schisandra chinensis (five-flavor berry): Based on the growth and flowering/fruiting habits of short fruiting branches, medium fruiting branches, long fruiting branches and basal shoots, the following pruning methods and principles are determined: since short fruiting branches have poor fruiting capacity, few should be retained; in particular, short fruiting branches that do not flower or bear only male flowers should all be pruned off. Medium and long fruiting branches are the main fruiting branches and grow vigorously; they should be thinned at a spacing of 10-20 cm to facilitate ventilation and light penetration and increase fruit yield. For basal shoots, select and retain 3-4 thick, strong branches per plant as renewal branches, and cut off all the rest. II. Magnolia biondii

Schisandra intercropping pattern offers good returns
Northern Schisandra is derived from the mature dried fruit of Schisandra chinensis of the genus Schisandra in the family Magnoliaceae. The plant is a perennial deciduous woody climbing vine, with woody stems reaching 8-10 m long. It grows wild in forests and forest margins, climbing trees. It flowers from May to July each year, and the fruit ripens from August to early October. The ripe red spike-like berries are picked for medicinal use. Schisandra cultivation techniques (1) Suitable growing environment for Schisandra. Schisandra prefers a cool, moist living environment and is shade-tolerant, with a suitable shading level of about 20%. The first
