Introduction to Pollution-Free Production Techniques for Jasmine
I. Site Selection Pollution-free jasmine, like organic jasmine, is produced in unpolluted places. Although the requirements are not as strict as those for organic jasmine, its production environment has specific requirements for soil, water sources, atmosphere and ecology. Therefore, the site must be far away from urban areas, residential areas, factories and mines, and main highway routes, and must be a place with fresh air and clean water sources. II. Production Management For pest and disease control, the focus should be on winter protection and pruning to clean the garden. (1) Winter protection From the eleventh to the twelfth lunar month, take advantage of rising temperatures, when pests come out to activity and their resistance is relatively weak, spray 1-2 times with 500-600 times lime sulfur mixture or 300-500 times orchard cleaner to reduce the overwintering pest and disease base.

Key Techniques for Pollution-Free Cultivation of Edible Lilies
Lilies belong to the Liliaceae family. Their flowers are ornamental, and the fresh bulbs are a vegetable with high nutritional value and great medicinal value. Growing lilies is highly profitable. The pollution-free cultivation techniques for edible lilies are introduced below: (1) Scientifically select the site and insist on crop rotation. Although lilies are widely adaptable and can be grown in many types of soil, it is best to choose plots with high terrain, smooth drainage, loose soil and fertile soil. Plots whose previous crop was pepper, eggplant or similar crops should not be chosen. Continuous cropping and repeated cropping on the same land are most taboo. At the same time, crop rotation must be carried out to help build soil fertility

How to carry out pollution-free cultivation of lilies? Detailed explanation of technical points
Selecting a pollution-free area for planting requires a good ecological environment, with no industrial "three wastes" or pollution from agriculture, urban domestic life, or medical waste within 3 kilometers around, avoiding main highway lines (more than 100 meters), and no pollution of irrigation water, atmosphere, or soil, meeting the air environment quality standards (GB3095-1996) and irrigation water quality standards (CB5084-92) stipulated by the state. At the same time, in order to reduce pesticide use, choose field soil where Liliaceae crops such as lilies, garlic, and leeks have not been planted in the past 3-5 years, paddy field

Detailed Explanation of Pollution-Free Lily Cultivation Techniques, Part Two
1. Pre-emergence management. From lily planting to around mid-February of the following year, the main tasks are clearing ditches and draining water well, ensuring the lily field is neither drought-stricken nor waterlogged, with neither high-temperature drought nor low-temperature frost damage, so as to ensure normal growth of the bulb root system. From December to January of the following year, splash-apply 20-30 dan of rotted pig manure and urine per mu. Before emergence, if the lily field is not covered with plastic film or rice straw, a pre-emergence herbicide such as Roundup or glyphosate may be applied. At the same time, before the lilies emerge, cultivate 1-2 times, which can not only remove weeds and raise

Detailed Explanation of Pollution-Free Lily Cultivation Techniques (Part 1)
Lily is the general term for all species in the genus Lilium of the family Liliaceae, subclass Monocotyledoneae, and is a perennial herbaceous crop with fleshy roots. Because its underground bulb is formed by many scales clasped together, it is named "lily." The lily is not only a specialty vegetable of our country, but also has high medicinal value; since ancient times it has been a good medicine for treating illnesses. It has the effects of clearing the lungs and moistening dryness, nourishing yin and clearing heat, tonifying the spleen and strengthening the stomach, calming the heart and soothing the nerves, promoting urination and relieving constipation, resolving unnamed swellings and toxins, and stopping bleeding, and it has good health benefits for the human throat, lungs, stomach, intestines, and so on. According to research, the lily alkaloids in lily such as lily glycoside A,

Detailed explanation of key techniques for pollution-free lily cultivation
Lily belongs to the Liliaceae family. Its flowers are ornamental, its fresh bulbs are a vegetable with relatively high nutritional value, and it also has high medicinal value; growing lilies yields relatively high economic returns. The pollution-free cultivation techniques for lily are introduced below: Scientific site selection and rational crop rotation. For lily, it is advisable to choose plots with relatively high terrain, unimpeded drainage, loose soil and fertile soil. Plots whose previous crop was pepper, eggplant or similar crops should not be chosen. Continuous cropping and repeated cropping are most taboo.

Detailed Explanation of Pollution-Free Processing Technology for Dried Lily Slices
Lily is one of the important health vegetables. The traditional processing method is to blanch the harvested lilies and then dry them in the sun. With this drying method, the dried lilies still have a relatively high moisture content, are not resistant to storage, and are still prone to discoloration. For this reason, some farmers use sulfur fumigation, which affects the safety and quality of the lilies. However, after dehydration and drying, the lilies have a low moisture content and, after color protection and blanching, are not prone to discoloration, which better solves the quality and safety problem of lilies being affected by sulfur fumigation. 1. Process flow: fresh lily bulbs -> selection

Pollution-free control methods for pests and diseases in flowers, trees and bonsai
Alcohol swabbing method: gently swab the leaves of orchids infested with scale insects using disinfecting alcohol; this can kill the scale insects, and in the following year there will rarely be any scale insect damage. Vinegar swabbing method: soak a cotton ball in edible vinegar (rice vinegar), then gently swab the leaves of camellias; this not only kills scale insects but also restores the damaged leaves to a green, glossy condition. Iodine swabbing method: when dry rot is found on the trunk of a stump bonsai, immediately use a blade wiped with iodine to scrape away all the rotted parts, reaching down to the xylem, then apply iodine to the main trunk; one week

Analysis of Key Points of Pollution-Free Cultivation Techniques for Bonsai
A. Steiner, chairman of the International Pollution-Free Cultivation Association, clearly defined pollution-free cultivation as nutrient solution cultivation. Plants center on the physiological functions of inorganic nutrient elements. Pollution-free cultivation refers to the use of inorganic nutrient solutions to directly provide plants with the nutrient elements essential for growth, replacing the cultivation method in which soil and organic matter normally provide nutrients to plants. In pollution-free cultivation, the nutrient solution can be sprayed directly onto the root system (aeroponics), or plants can be grown directly in a flowing inorganic nutrient solution (hydroponics), or sterilized microporous inorganic minerals
