Lily virus disease (lily symptamless virus)
The common lily virus diseases are Verticillium wilt and mosaic. There are no special disease spots on the verticillium wilt leaves, the whole plant is yellowish and the internodes are shortened. The plant is dwarfed, and the leaves are yellowed and atrophied. Irregular light green mottles are produced on the mosaic leaves, and then the small light green parts are connected and enlarged, forming slender yellow spots along the veins, and later slightly sunken, turning yellowish brown to reddish brown. The virus overwintered mainly in the bulb and became the source of infection at the beginning of the second year, and the reinfection in the field was mainly caused by aphids. There are many diseased bulbs, dry weather and aphids.

Control measures of Lily Diseases
The prevention and control of epidemic disease (1) the use of high box deep trench or ridging cultivation requires that the border surface should be flat in order to facilitate the elimination of the water system, and the diseased plants should be dug out as soon as possible, burned or buried deeply. (2) adopt the technology of formula fertilization and appropriately increase the application of potash fertilizer to improve the disease resistance. (3) spraying 250 times of 40% triethyl aluminum phosphate wettable powder or 58% metalaxyl and manganese zinc wettable powder, 64% poison alum 500 times, 72% DuPont Kelu 800 times.

The main epidemic factors of Lily Diseases and the skills of Integrated Control
First, symptoms: on leaves, stems and bulbs. The leaves are susceptible to disease, causing them to wither. The initial leaf tip turns brown, the length 1-2mm, and then gradually aggravates, the disease spot expands into a nearly triangular, thinning, dry and withered shape, with cloud patterns on it. The length of disease spot is generally 17-28mm, the width is 5-8mm, the maximum length of disease spot is 56mm, the width is 12mm, and finally the leaves die, and some of them occur at the leaf edge, which is semi-oval brown disease spot, which can also lead to leaf death.

Lily sowing period
It is suitable for mid-late September in the Central Plains; in alpine areas, it is too late, too little rooting before winter, not flourishing in the beginning of spring, and unfavorable emergence of seedlings; too early, the ground temperature is too high, and the bulbs are susceptible to disease and rot, resulting in lack of seedlings and weak seedlings. The general principle is to be early rather than late. The daily average temperature is about 20 ℃, and there is no high temperature above 32 ℃. The best sowing time is sunny day after rain.

Propagation technology of lily
It is mainly propagated by scales, bulbs and bulbs. First, cultivate the seed stem (1) scale propagation when the leaves of lilies begin to turn yellow in autumn, select strong and disease-free plants, dig up the bulbs, cut off the base, separate the scales, take the inner scales, plant them in trenches according to plant spacing of 3 cm and row spacing of 17 cm, cover the grass to preserve soil moisture from September to October. After planting, the bulbs grow from the cut, develop into new plants in the spring of the second year, and then colonized or cultured continuously for 3 years in autumn.

Propagation and cultivation techniques of Lily
First, efficacy and distribution of lilies, also known as mountain lilies, medicine lilies, wild lilies, microphones, rock lilies and so on. Lily is excellent in both food and medicine, with bulbs for edible or medicinal purposes, with the effects of moistening the lungs and relieving cough, clearing the heart and calming the mind. Main treatment of lung heat cough, blood in sputum, restlessness, restlessness, nosebleed, amenorrhea and other symptoms. As a non-staple food, it can moisturize the lungs and relieve cough. It is cultivated all over the country. Second, the main breeding methods are bulbs, scales and bulbs, and seeds can also be used for propagation. Among them, it is divided into small scales.

Propagation method of lily
1. The young bulbs of Lilium bulb should be cultivated continuously for several years and reach a certain size before they can be harvested and eaten. The bulbs used for sowing in the year of harvest are called bulbs. The main results are as follows: 1) this method is suitable for varieties that can produce pearl teeth, such as Yixing lily, more than half of the leaves and leaf axils of Yixing lily can grow bulbs, and each plant can produce more than 40-50 buds. 2) the bulbs, namely bulbs, were cultivated with bulbs, which were born in the soil at the base of the aboveground stem. Many lilies can form bulbs, such as Lanzhou lily, each lily can

Introduction of cotton varieties
The whole growth period of Xinqiu No. 1 is about 130 days. Good seedling emergence, strong growth in the early and middle stage, and good leaf function in the later stage. The plant type is compact. Fruit branches have high nodes, few superfluous buds, and are easy to manage. The yield is good, the boll setting is strong and concentrated, the boll is large, oval, and the boll weight is 6.4 grams. It is smooth and concentrated. The lint percentage is 41%, and the pre-frost flowering rate is 93.5%. High resistance to cotton bollworm, resistance to Fusarium wilt, resistance to Verticillium wilt, less crazy branches, easy to manage. The average yield per mu is about 400 kg. Generally, there are 3000 plants per mu of 2500mu.
