Key Technical Points for High-Yield and High-Quality Cultivation of Garlic with Plastic Mulching
Garlic is currently one of the main cultivated vegetables in the Laixi area, with a cultivation area of over 200,000 mu over the years. To increase the economic income of local garlic farmers, since 1998 we have conducted experimental research and extension of large-scale high-yield and high-quality garlic cultivation technology with plastic mulching. In the demonstration park, the average yield per mu is 1,000 kg of garlic scapes and 1,000 kg of garlic bulbs, with the highest yield per mu exceeding 1,250 kg. The garlic scapes produced are green and tender, and the garlic bulbs are plump, white, strongly pungent, and highly viscous, with strong market competitiveness. They are exported in large quantities, and the economic benefits are considerable. The main techniques are summarized below.

Detailed Explanation of Processing Methods and Technical Points for Allicin
Allicin is a volatile oily substance extracted from the spherical bulbs of garlic, a mixture of diallyl trisulfide, diallyl disulfide, and methyl allyl disulfide, among others. The trisulfide has a strong inhibitory and killing effect on pathogenic microorganisms, and the disulfide also has certain antibacterial and bactericidal effects. 1. Material preparation. Select mature, dry garlic heads free from insect damage and mildew, remove the stems, separate the cloves, peel off the inner skin, rinse with clean water, and remove impurities and substandard garlic cloves. 2. Crushing and drying. Use a grinder to crush the garlic

Control Methods and Technical Key Points for the Chestnut Gall Wasp
The chestnut gall wasp Dryocosmus kuriphilus Yasumatsu belongs to the order Hymenoptera, family Cynipidae, and is also known as the chestnut tumor wasp. It is widely distributed in chestnut-growing areas, where its larvae damage the new buds of chestnut trees. When chestnut buds sprout in spring, the damaged buds fail to sprout and gradually swell to form galls, sometimes with deformed small leaves growing on the galls. In severe cases, the tree vigor weakens and branches or the whole tree may die. Morphology: adult body length 2.5-3 mm; head and abdomen dark brown;

Detailed Explanation of Lily Cultivation Methods and Key Technical Points
Climate and Soil The tiger lily prefers a sunny, mild and relatively dry climate. It is cold-resistant and drought-tolerant, and dislikes extreme heat and excessive rain. It has low requirements for soil; it is best to plant it in a cool, dry, sunny environment and in a high, dry, sunny, well-drained sandy loam. Damp, low-lying land is not suitable for planting. Continuous cropping is avoided. Land preparation is carried out in summer: plow the land, apply base fertilizer, form flat beds about 1.2 m wide, and dig drainage ditches around them. Propagation methods mainly use scales and small bulbs. (1) Scale propagation: select large, healthy bulbs free of pests and diseases, and use a bamboo

Harvesting and Processing Methods and Technical Key Points for Lilies
In the autumn of the second year after transplanting, when the stems and leaves wither, choose a sunny day to dig them up, remove the stems and leaves, use the large bulbs for medicinal purposes and the small bulbs as planting stock. Separate the large bulbs into scales, place them separately according to large, medium and small sizes, wash off the soil, drain off the water droplets, then put them into water and blanch briefly, about 10 minutes for large scales and 5-7 minutes for small scales, remove them, rinse off the mucus in clear water, spread them out on mats to dry, and when they are 90% dry, fumigate them with sulfur, then sun-dry them until completely dry. The yield is about 200 kg of dried product per mu.

Detailed Explanation of Key Technical Points for Field Cultivation and Management of Lilies
When carrying out field cultivation, the following aspects of work should be done well. (1) Select good varieties according to the cultivation purpose and local climate conditions, soil, and other factors. (2) Choose a suitable plot: select sloping land with high and dry terrain (with a gentle slope) or flat land, with loose, deep soil and medium organic matter content, and the plot should have good drainage capacity. For plots prone to drought, it is better to have a certain irrigation capacity. In addition, lilies are unsuitable for continuous cropping; a plot where lilies have been grown can only be planted with lilies again after 3-5 years, and the previous crop is best

Key Technical Points for Environmental Control in Greenhouse Lily Cultivation
In lily cultivation, besides having high-quality bulbs, strict control of the growing environment according to the requirements of different varieties throughout the entire growth process is also needed to produce lily products with good plant form and high quality. If conditions are not well controlled, it will not only affect the plant form of the lilies, but in severe cases also affect plant growth, and may even prevent normal flowering. The following briefly introduces environmental control during lily cultivation based on the requirements of lily planting. 1. Greenhouse A good growing environment can ensure the normal growth of lilies.

Key Technical Points for Imitation-Wild High-Quality Cultivation of Oyster Mushrooms in Winter and Early Spring
Oyster mushrooms produced using imitation-wild cultivation techniques not only taste as fresh and delicious as wild ones, but also truly achieve ecological, high-quality, and high-yield production. Even in the cold winter and low-temperature early spring seasons, high-quality oyster mushrooms that are thick, fleshy, fresh, and tender can be produced in a relatively enclosed shade shed by making full use of ground temperature. This method increases yield by more than 60% compared with conventional cultivation methods, and by more than 40% compared with cultivation methods such as mushroom walls, with a biological conversion rate of more than 220%. 1. Mycelium culture. Use high-pressure or atmospheric-pressure sterilization, inoculate conventionally, and culture until physiologically mature mycelium is obtained.

Key Technical Points and Detailed Methods for Oyster Mushroom Cultivation
Plastic bag cultivation saves labor, is easy to manage, makes full use of mushroom house space, reduces pests and diseases, and makes cultivation success easier. It is suitable not only for indoor cultivation, but also for cultivation in plastic greenhouses, air-raid shelters and other places, and the bags can also be placed in paddy fields, corn fields and vegetable plots for intercropping with rice, corn and vegetables. This is a new cultivation method that has been widely adopted in recent years. 1. Specifications for plastic bags: choose plastic tubes (open at both ends) 0.03-0.04 cm thick, 24-30 cm wide and 40-50 cm long.

Brine Processing Method and Technical Key Points for Oyster Mushrooms
Oyster mushroom, also known as abalone mushroom, is an edible fungus that can be eaten fresh or processed into canned goods for export, and is extremely rich in nutrients. Brine processing of oyster mushrooms is simple to operate, easy to transport, and offers relatively high economic returns. Grade standards for oyster mushrooms (divided into 2 grades in total). Grade 1 mushrooms: grayish-white in color, 3-12 cm in diameter, without stems; the few with stems must not exceed 1 cm. The tissue is tender, the shape is complete, the edge of the cap has no severe shrinkage or cracks, no mud, sand or other impurities, no pests or diseases, no shrinkage or deterioration, no off-odor, and must not be soaked in water. Grade 2
