Control Methods for Lily Mosaic Virus (CMV)
Symptoms: Chlorotic mottling or necrotic spots appear on the leaves. Pathogens: Lily latent virus [Lily latent virus] and Cucumber mosaic virus [Cucumber mosaic virus] (abbreviated as CMV). Lily latent virus is widespread in Lilium plants; some lilies show no symptoms after infection with this virus, while others develop chlorotic mottling symptoms. Cucumber mosaic virus causes chlorotic mottling symptoms, and if this disease co-occurs with lily latent virus, lesions develop. Transmission route: The green peach aphid and other aphids are the vector insects that spread the virus.

How Do Lilies Reproduce? A Detailed Guide to Several Propagation Methods
There are many species of lilies, and when propagating them, suitable measures can be taken according to the different species. The following are the common methods: Sowing method: The seeds are sown immediately after collection, or they can be sown again in the spring of the following year. During the seedling stage, shading is necessary, and water and fertilizer management should be strengthened. By autumn, small bulbs can form. The flowering time varies depending on the lily species; for example, Lilium longiflorum (Easter lily) can bloom in one year. Dividing and planting small bulbs: The mother plant forms small bulbs on the underground stem nodes, and sometimes small bulbs can also form at the base of the mother bulb. In autumn, separate them from the mother bulb and plant them separately or

What are the control methods for common lily diseases?
Several common diseases of lilies: lily mosaic virus, bulb rot, leaf spot, leaf blight, etc. Mosaic virus is also called lily latent mosaic virus. When the disease breaks out, chlorotic spots or necrotic spots of uneven depth appear on the leaves, the affected plants are stunted, the leaf margins curl, and the leaves become smaller. Sometimes spindle-shaped light brown lesions appear on the petals, the flowers are deformed, and they do not open easily. Control methods: 1. Select virus-free bulbs for propagation; 2. Strengthen the control of aphids and leafhoppers; 3. Promptly pull out and destroy diseased plants. Leaf spot disease: when this disease first appears, the leaves

Identification and Control Methods for the Lily Pest Cotton Aphid
Its harm to plants is second only to the green peach aphid, and it also has many host species, mainly chrysanthemums, lilies, and others. Morphological features: female aphids are winged or wingless, extremely small in size, initially pale yellow, later black. Legs and antennae are yellow-white. Male aphids are all wingless, 1/3 shorter than female aphids, and similar in color. Eggs are oval, yellow when first laid, turning black when hatching. Nymphs are gray-white at first, later turning yellow. When mature, those with wing buds on the thorax and back are winged mother aphids, while those without wing buds are wingless mother aphids. Damage habits: the cotton aphid can produce 20 generations a year, overwintering as eggs on plant

What are the control methods for lily pests?
The main lily pests include aphids, scarab beetles and others. In addition, there are also damage from root-knot nematodes, cutworms and others. The peach aphid is the most widespread aphid pest on plants. Control: eliminate overwintering sources of the pest, clear away nearby weeds, and carry out thorough clearing of the garden and field. During the aphid damage period, spray 40% dimethoate or omethoate at 1200 times dilution, or aphid-killing pine emulsion at 1500 times, or 2.5% fish essence at 1000-1500 times. Protect natural enemies, that is, protect the seven-spot ladybird, hoverflies and green lacewings, etc. White grubs are the larvae of scarab beetles, mainly

Detailed Explanation of Lily Storage Methods and Processing Techniques
(1) Lily Storage Methods Lily is generally stored using the cellar (pit) sand storage method, or the basket (box) indoor storage method can also be used. The specific procedure is: 1. Harvesting. When the lily plant withers and the underground bulb matures, choose a sunny day for digging. The bulbs harvested at this time have high yield, good quality and are resistant to storage. Then cut off the aboveground part and the fibrous roots and seed roots. 2. Pre-cooling. Spread the bulbs evenly in a cool and ventilated indoor area to dissipate heat for 2D3 days. The pile height should preferably be 2D3 fruit bulbs high. The heat dissipation time should not be too long, to prevent the scales from discoloring. 3. Fruit selection. Select

Key Points and Detailed Methods for Lily Storage and Fresh-keeping Technology
Lilies prefer warmth and are afraid of cold; after being exposed to wind, the scales will turn red and shrivel. There are many storage methods, and the yellow sand burial method is especially effective. The specific method is: build a burial pit indoors with bricks or cement, or use wooden boxes, baskets, etc. as containers. First spread a layer of yellow sand about 20 mm thick on the bottom of the container, then place one layer of lilies and one layer of yellow sand, stacking to about 50 mm from the container opening. Then cover with yellow sand again so that the lilies are not exposed to the air. What should be noted with this method is: the containers used for storage should first be disinfected with 0

Detailed Guide to Lily Planting Methods and Topdressing Techniques
Planting: (1) Digging trenches: the direction of the trench should be perpendicular to the direction of the bed, with a trench depth of 5-10 cm. (2) Placing the bulbs: be careful to protect the newly grown tender roots. (3) Covering with soil: the soil cover should be slightly higher than the bed surface to help preserve moisture and drainage. Topdressing: (1) Mainly use chemical fertilizers containing mainly nitrogen and potassium; some liquid organic fertilizers such as soybean cake water can also be used. Lilies generally do not need phosphorus fertilizer; phosphorus can be provided by organic fertilizer. (2) Fertilization timing. One month after emergence, apply soybean cake water and 0.5% ammonium sulfate; apply a mixture of 0.2% potassium nitrate plus 0.2% ammonium sulfate. After flower buds appear, foliar

A Detailed Guide to Lily Cultivation Techniques and Propagation Methods
As an important and valuable cut flower, lilies are the focus here as we introduce their cultivation techniques and propagation methods: 1. Cultivation techniques: (1) Selection of planting site: The planting site should be chosen with high, well-drained terrain, loose soil, rich in humus, and deep, loose soil layers. Most species prefer slightly acidic soil. Avoid continuous cropping. (2) Soil treatment: Since cultivating lilies does not require the vast land area of field crops, the soil environment can be improved by replacing soil locally. First, dig out the original soil from the rows where lilies are to be planted, mix leaf mold, peat, fermented sawdust, vermiculite, perlite and other media with soil in certain proportions and fill them into the planting furrows. Alternatively, mix the above materials at a ratio of 1/3 to 1/2 with ordinary soil before planting lilies, which is also a very ideal soil medium. A single brick wall 30 cm high can also be built. If conditions permit, a raised planting bed can be built, using cement boards, bricks and other building materials to build a trough-style planting bed 50-80 cm above ground, filled with artificially prepared nutrient substrate, which facilitates drainage, aeration and ventilation, makes soil disinfection easier, and also cuts off the connection with the ground soil to reduce the chance of underground pathogen infection. However, this kind of facility is relatively expensive, so growers should act according to their means. After the substrate is placed in the planting bed, use sulfur powder or lime and other substances to adjust the pH to between 5.5-6.5, or adjust the pH according to the soil requirements of different lilies. A soil depth of 40 cm is appropriate. Lilies are sensitive to salts; high salinity hinders growth, and total salt content must not be too high. If too much saline organic fertilizer or chemical fertilizer is applied, it can easily exceed the limit. Therefore, soil analysis should be carried out at least 6 weeks before planting, and if salinity is too high, it should be leached. The soil should be free of pests and diseases, and can be disinfected with steam or fungicides and insecticides such as dexon and phoxim.
