Tulip, also known as grass musk and lotus, has the following characteristics: 1. Sex likes a warm, moist, sunny or semi-overcast environment. The bulb can survive the winter in the open field under proper protection. Avoid the heat of summer, so the aboveground parts gradually wither into dormancy from June to September. The optimum temperature for tulip growth is 15-18 ℃, the rooting temperature is more than 5 ℃, the optimum temperature for flower bud differentiation is 17-23 ℃, and more than 35 ℃ will be inhibited. The cue ball gradually withered a month after flowering, and a new one formed at its base.

Control of Tulip Black Rot
Symptoms: bulb disease. Stem disk and stem surface, sometimes on the 2nd and 3rd scales, producing irregular black-brown spots at the beginning, rough surface. Pseudomonas andropogonis (Smith)Stapp belongs to Pseudomonas bacteria. The thallus is rod-shaped, 1.9*0.8 μ m in size, and has 1 - 3 flagella. The optimum temperature for disease onset is 20~25℃, and the lowest temperature is 5℃. Pathways of infection: infected bulbs and diseased bodies in soil are the sources of infection. Control methods: try

Control of Brown spot of Tulip
Symptoms: the infected leaf buds are malformed and curled, and the leaves that grow up after the tender buds are damaged become curly. If the environment is humid, a large number of gray mold conidia will be produced on the diseased tissue, which will affect the nearby healthy plants and make the leaves susceptible, so the growth of the bulb will be greatly affected. After the flowers are injured, white or light yellowish brown spots begin to appear, then expand rapidly and wither, or turn brown and dry. Banding also appears on the pedicel, and the conidium sometimes occurs above it. At every stage of the disease

tulip rot sclerotinia
Tulip rot sclerotinia disease, pathogen belongs to semi-known fungus sclerotinia, mainly harm seedlings and bulbs. After the seedlings are infected, the leaflets die as soon as they are pulled out. Bulbs damaged, external scales occurred soft rot, and in the infected part and the surrounding soil surface appeared many white silk hypha, after the formation of many rapeseed sclerotia. After the formation of many sclerotia, sclerotia initially white, brown after. Pathogenesis of this disease depends on mycelium and sclerotia transmission, sclerotia winter in the soil, in high temperature and high humidity conditions, the disease occurs heavily. A, collection.

Tulip Pythium root rot
The disease can be caused by ultimate Pythium, abnormal female Pythium and intermediate Pythium, all of which are caused by oomycetes. The pathogen overwinters in the diseased bulbs, diseased roots and soil, and often spreads with the movement of the diseased soil. The soil temperature is high, the drainage is not timely after rain, and the moisture retention time is long. Symptoms: at the beginning of the disease, translucent water stains appeared in the roots, which caused browning of vascular bundles and root rot. After the bulb is infected, gray spots appear around the base of the bulb, and the edges are brown. In severe cases, the bulb is soft rotten, and diseased scales are planted.

Local techniques for propagation and cultivation of tulips
Producing area and habit tulips prefer loose and fertile sandy soil with high dryness and good drainage, growing well in leeward and sunny places, but should be properly shaded in summer. Cold-resistant, moisture-resistant, do not like the sun, winter temperature in-3 ℃-5 ℃ fashion can grow, strong adaptability. The flowering period of tulip can be divided into early, middle and late, early flowering in March and April, middle flowering in April and May, and late flowering in late May. The florescence is short. Tulip is a spring bulb flower with early flowering and bright colors. It is a beautiful flower embellished with spring scenery.

Seed bulb propagation technique of tulip
Tulip propagation methods include bulb propagation, seed propagation and tissue culture. The latter two methods take a long time to reproduce (seed propagation takes 5 years to bloom) and cost high. In addition to special purposes such as breeding new varieties and virus-free, bulb propagation methods are generally adopted. Agricultural technology recommendation. The propagation materials are small bulbs harvested in June, dried in the shade after mud removal, stored in cold storage at 5-10℃, and ventilation should be paid attention to. Tulips like loose soil, good permeability of sandy loam, ball propagation should choose good drainage, Yang

Out-of-season soil-covered bag planting technique of Lentinus edodes
Soil-covered bag cultivation of Lentinus edodes is a new mode of Lentinus edodes cultivation. The Lentinus edodes cultivated in this model has the advantages of good mushroom shape, high yield, easy to produce mushrooms, time-saving and labor-saving. It is also a more advanced method in the cultivation of Lentinus edodes at present, especially the off-season soil-covered bag cultivation of Lentinus edodes to produce high-quality Lentinus edodes in summer and autumn, with high market price and good economic benefits. The technology has been tested and popularized in the north of Guangdong province, and the effect is good. The techniques of off-season soil-covered bag cultivation of Lentinus edodes are introduced as follows: first, the seasonal arrangement has the advantages of high temperature resistance, round mushroom, thick meat, thick mushroom stalk and high yield.
