Cultivation and Management Methods and Technical Key Points for Cut-Flower Roses
Roses, with their brilliant colors and delicate fragrance, have always been cherished by people. Cultivating fresh cut-flower roses in solar greenhouses allows year-round supply to the market and is truly another new path for farming families to prosper. 1. Graft propagation. Use wild roses (Rosa multiflora) or dedicated rootstock varieties as rootstock, and adopt the branch grafting method or the bud grafting method for grafting. Sow the rootstock in early April and transplant in April of the following year. The seedbed should be fertile, loose sandy soil, with a plant-to-row spacing of 20 cm x 80 cm. Perform bud grafting in June, and lift the seedlings for field planting in the spring of the third year.

Open-field Cultivation Methods and Technical Key Points for Tea Rose
The tea rose is a plant of the genus Rosa, suitable for growing in environments with ample sunlight and good air circulation. It is not demanding regarding soil, but the following aspects should be noted in open-field cultivation. 1. Cultivation site. The tea rose is a light-loving plant, so a sunny location should be chosen during cultivation, avoiding planting beside tall buildings, under tree shade, or on the shady side of hillsides. The ideal soil for cultivating tea roses should have good granular structure and be rich in organic matter. The tea rose is not demanding regarding soil pH and can grow in soil with a pH of 5.5-8.0.

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

Detailed Explanation of Key Technical Points for Silkworm Disease Prevention and Control
In the process of rearing silkworms, the occurrence of silkworm diseases is closely related to the constitution of the larvae, pathogens, and environmental conditions. Silkworm farmers who do not thoroughly disinfect the rearing rooms and tools, who manage the rearing period with extensive techniques, and who provide poor environmental conditions create factors unfavorable to larval growth and development. These factors easily lead to invasion by pathogenic microorganisms, causing a decline in larval constitution and resulting in disease, which leads to mass outbreaks of illness in the larvae and causes significant economic losses for silkworm farmers. To effectively control the occurrence of larval diseases during the silkworm larval rearing period,

Processing Methods and Technical Key Points for Peach Crystals
(1) Process flow: raw material selection → washing → crushing → juicing → concentration → adding powdered sugar → stirring → forming → drying → packaging. (2) Technical key points: ① Raw material selection: choose fresh peach fruits with high ripeness, plumpness, abundant juice and strong aroma; remove diseased, insect-damaged, rotten and browned fruits; first soak the fruits in 0.5%-1.5% hydrochloric acid for 2-3 minutes, then rinse them clean with water, and it is best to wash off the peach fuzz. ② Cutting and pit removal: cut the fruits open with a stainless steel knife, then

Key Technical Points for Jujube Fruit Harvesting and Post-Harvest Management
The harvesting period of jujube varies greatly depending on the intended use of the fruit and the cultivar. 1. Fruit used for candied jujubes: the white-ripe stage is the suitable time for harvest. During this stage, the fruit stops increasing in volume; the green color of the peel fades, turning milky white or greenish-white; the peel is thin and soft in texture, and after boiling it does not easily separate from the flesh; the flesh is relatively soft, with little juice and low sugar content, but it is rich in protopectin and highly resistant to boiling. The processed product is yellow-orange and crystalline, appearing amber and semi-transparent, chewy and smooth with no skin residue when eaten, offering a distinctive flavor.

Harvesting, Processing Methods and Key Technical Points for Dwarf Lilyturf (Ophiopogon japonicus)
Dwarf lilyturf is harvested in the first or second ten days of April of the second or third year after planting. Choose a sunny day, first plow the soil to a depth of 25 cm so that the dwarf lilyturf is turned up, shake off the soil, cut off the tuberous roots and fibrous roots, put them separately into bamboo baskets, and place them in running water, trampling and rubbing them with the feet to wash away the mud and sand. Spread the washed dwarf lilyturf on a drying mat or in a drying yard to sun-dry; once the water has dried, rub it gently with the hands, then sun-dry again after rubbing, repeating this several times until the fibrous roots are rubbed off, then sun-dry until completely dry, and sieve out impurities to finish. If rainy weather occurs, use a gentle heat of 40-50°C to dry for 15-20 hours

How to control rice thrips? Control methods and technical key points
(1) Life habits: The rice thrips is very small, with adults only 1 mm to 1.5 mm long, dark brown. In winter, adults overwinter in gramineous weeds and on wheat crops. During the seedling-raising period of the following year, when the seedlings grow to 2 to 3 leaves, they fly into the seedling fields to lay eggs and reproduce. The insect body is small and very active, able to fly and jump. Adults are attracted to green, and after the seedlings are transplanted, they enter the tillering stage when food is abundant, which facilitates massive egg-laying and reproduction, damaging the heart leaves and young tender tissues. In the early stage of leaf damage, small white spots appear, and the upper part of the leaf tip curls inward, causing

Detailed Explanation of Practical Technical Points for Marble Goby Farming
The marble goby, scientifically named Oxyeleotris marmorata or Bostrychus sinensis, is a warm-water economic fish mainly produced in Cambodia, Thailand, Vietnam and other countries, commonly known as marble goby in Guangdong and South China. The maximum body length is 60cm, weighing up to 5--6kg. A tail weight of 0.3kg reaches commercial specification. The Thai marble goby belongs to the suborder Gobioidei, a carnivorous, bottom-dwelling, cave-dwelling fish that fears light and often hides in rock crevices and caves. The color of its body surface changes with the surrounding water quality and environment. Under natural conditions, its main food is small fish and small shrimp. The farming water temperature range is 15--33°C, suitable

Common Disease Prevention and Control Methods and Key Technical Points for Walking Catfish
I. Trichodiniasis: Large numbers of Trichodina (parasites difficult to see with the naked eye) attach to the gill filaments, damaging gill tissue, affecting respiration, and causing fry to suffocate and die. Prevention and control methods: (1) Per cubic meter of water, use 0.5 g copper sulfate and 0.2 g ferrous sulfate (or 0.7 g copper sulfate alone), dissolve in 40-50°C warm water, and splash over the entire pond. (2) Per cubic meter of water, use 0.5 g of 50% amobam, dissolve in water, and splash over the entire pond. II. Gyrodactyliasis and Dactylogyriasis: These two parasites attach in large numbers to the gills and secrete large amounts of mucus, hindering
