Prevention and Control of Edible Fungi Diseases and Formula of nutrient solution for soilless cultivation of Flowers

Compared with soilless culture flowers, soilless culture flowers have the following advantages: good ⑴ quality. The nutrient solution of soilless cultivation of flowers is prepared according to the needs of flower growth, so the cultivated flowers are large and many, strong taste, colorful and long flowering period. ⑵ saves nutrients, water and labor. Soilless cultivation of flowers as long as regular supplement of nutrients to the plant, easy to operate, labor-saving and time-saving. ⑶ is clean, no weeds and few diseases and insect pests. The soilless cultivation of flowers mainly focuses on the following two points:

First, matrix preparation. The main function of soilless culture substrate is to fix flowers and plants in containers. At present, the commonly used soilless culture substrate in China: sand grains with a diameter of less than 3 mm of ⑴. Natural gravel, pumice and volcanic rocks with a diameter greater than 3 mm of ⑵. ⑶ has good buffering property and does not sink in water of mica mineral vermiculite. ⑷ perlite. The effect is better when it is mixed with mudstone and sand. ⑸ has good air permeability and strong water-holding capacity of peat. It can be used as a matrix alone or mixed with slag. In addition, slag, bricks, charcoal, asbestos, sawdust, fern root, bark and so on can be used as substrates. The matrix should be washed and disinfected before use.

Second, the preparation of nutrient solution. The various elements and their dosage used in the preparation of nutrient solution for soilless cultivation of flowers should be determined according to the varieties of flowers planted and their different growth periods and regions. In this paper, a formula is introduced: adding 0.22 grams of ammonium phosphate, 1.05 grams of potassium nitrate, 0.16 grams of ammonium sulfate and 0.16 grams of ammonium nitrate, and 0.01 grams of ferrous sulfate in 1 liter of water. Containers for preparing and storing nutrient solutions should be ceramic, enamel, plastic or glassware, not metal containers. Usage: potted flowers are irrigated with nutrient solution once a week during the growing period, and the dosage can be flexibly controlled according to the plant size.

3. Several common hydroponic plants are as follows: most of them are plants with inflated bulbs and some aquatic plants.

"Narcissus: any of various plants of the family Amaryllidaceae, having large bulbs with abundant nutrients and white fleshy roots at the base, placed in a container in autumn and winter, protecting the roots with beautiful pebbles or colored stones, or allowing the roots to grow as much as possible." Generally, it can blossom in 60 days when it is cultivated indoors. Buy a pot indoors in winter, clean and elegant, fragrance overflowing, is used as a traditional festival flower. The cultivation of daffodils does not need to add any nutrients, it can grow very well, generally in order to prevent overgrowth, let it receive sunlight during the day, pour the water out of the container at night, and protect the roots with wet gauze, so that it can control the overgrowth and be healthy and beautiful.

Hyacinth: a plant of the family Liliaceae and a bulbous flower. The method of hydroponics is also relatively simple. Choose and buy a bottle of container that can hold the bulb, it is better to buy a bottle of gourd-shaped container with a transparent glass texture, the water temperature should not be high, under 15 ℃, put the bulb on the bottleneck, after the root, you can lower the water level to the root just can touch the surface of the water, so that the root can fully absorb oxygen and promote the growth of the root. When the root develops, the black cloth covers the culture container and allows the bulb to develop further. In winter, the container should be moved to a sunny place to promote large and strong flowers, plump hyacinth inflorescences, diverse colors, and white roots. Can also plant several hyacinth in the fish tank, the matrix with sand, supplemented by shady ferns, to form a wild interesting small scene, but also very chic. The containers of water-raised plants should be beautiful and chic, and sometimes some household utensils such as goblets and bottles can be selected, as well as large-mouthed containers. Table head, case several put a basin of water to raise plants, the water is clear and colorful, refreshing and refreshing.
