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

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,

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

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.

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.

Pruning Methods and Technical Key Points for Cut Rose
Roses (Rosa spp.) are deciduous or evergreen shrubs of the Rosaceae family, with large, abundant blooms, graceful flower forms, rich colors, and varied fragrances, making them deeply loved by people and one of the four major cut flowers on the international market today. Roses grow and bloom continuously throughout the year, consuming large amounts of nutrients within the plant. If allowed to grow naturally, old branches will quickly die back. To prevent roses from aging, extend the peak flowering period, and harvest large quantities of high-quality cut flowers, it is essential to regulate them through training and pruning. Through pruning, main branches and flower branches can be developed, tree vigor can be regulated, and ventilation and light conditions can be improved.

Cut Rose Powdery Mildew Control Methods and Key Technical Points
Powdery mildew is one of the most important diseases of roses, damaging leaves, young shoots, flower buds and pedicels. The control methods are as follows: Strengthen cultivation management and promptly remove diseased plant residues; prune in good time to improve ventilation and light conditions; nitrogen fertilizer should not be excessive, and phosphorus and potassium fertilizers should be appropriately increased. Chemical control: when the disease occurs during the growing season, spray 15% triadimefon wettable powder at 2000-4000 times dilution or 50% thiophanate-methyl wettable powder at 1000 times dilution; 50% benomyl wettable powder at 1000 times dilution; 30% triflumizole at 800-10

How to grow azaleas with soilless culture? Master these key technical points
1. Preparation of the substrate. Azalea roots are very fine and require a loose substrate to facilitate aeration and drainage. Mix 1 part vermiculite, 1 part perlite sand, 1 part river sand, and 1 part coal cinder in proportion. After mixing the substrate, sterilize it with a 0.1% carbendazim solution, stir it evenly into the substrate, and cover with plastic film for 1 day. Then rinse it multiple times with clean water, and after air-drying, mix it evenly with a 0.4% agricultural compound fertilizer solution, then cover with plastic film for one month, after which it can be used for potting. 2. Preparation of the nutrient solution. Azaleas have relatively strict fertilizer requirements. During the growing period, apply light fertilizer frequently.

Soilless Cultivation Management Methods and Technical Key Points for Phalaenopsis
1. Temperature. During the vegetative growth period, the temperature is generally controlled at 20-35°C. The temperature required for vernalization of large seedlings is 15-18°C. The temperature requirements from spike emergence to flowering are 18-20°C at night and 25-30°C during the day. The best ornamental temperature during the flowering period is preferably controlled at 15-20°C. The day-night temperature difference is generally greater than 10°C, and a negative day-night temperature difference should especially be avoided. 2. Light. For small seedlings (from removal from the flask to 6 months of age), the light intensity is controlled at 5000-8000 lux; for medium seedlings (6 months to

Spruce Seedling Transplanting Methods and Technical Key Points
I. Selection of Afforestation Site According to the geographical location and climatic characteristics of the afforestation site, select microclimatic conditions suitable for spruce growth, especially moisture conditions. Under suitable microclimatic conditions, emphasis should be placed on selecting soil with deep soil layers, loose texture, and rich organic matter. In places with poor site conditions and sparse vegetation, cultivation measures must be strengthened to improve soil fertility. To ensure the shade tolerance and moisture requirements needed for spruce growth, in 2002 in Wulasitai Township our farm changed the traditional seedling planting method, selecting seedlings with a height of 50 cm or more, digging planting holes of 40 x 40 x
