Lotus seedling six

Lotus hydroponics is a kind of cultivation mode which is cleaner, more advanced and more suitable for industrial production based on soilless cultivation. Hydroponic lotus with clean, leaf viewing, flower viewing, fruit viewing, root viewing effect is good, easy maintenance and other characteristics won the favor of lotus people, become a new fashion of flower cultivation. Due to the lotus stem lying in water, the nature of the root water, lotus from the date of lotus seed breeding and soaking seed, with water, its rhizome-like channels store air, long-term completely immersed in water without asphyxiation, retting, so lotus is particularly suitable for cultivation. 1. Basin: Because there are many ventilation holes in the stems of lotus flowers in the water, it increases its buoyancy by water. If you follow the general hydroponic container, the lotus roots will inevitably float, the plant will tilt, and can not grow normally. How do you make lotus roots grow in matter-free water without floating? Think of the role and structure of the separation grate in the aluminum pot most commonly used in the family, and the problem is solved. Plastic basin or glass basin with mesh grate layer, the whole flowerpot does not leak and has decorative function; The lower layer of the pot is the root growth layer, which is restricted by the grate and cannot float, and its leaf buds and flower buds can extend the water layer from the mesh to the air. 2. Nutrient solution: At present, the nutrient solution required for lotus hydroponics is mostly prepared by the producers themselves. In the second week of hydroponics, 20 grains of nitrogen, phosphorus and potassium were added to the basin. After dissolved in water, the transparent liquid without impurities was added to the upper part. In the fourth week, add the Clivia hydroponic fertilizer sold in the flower market, and use it according to the instructions on the package. These two fertilizers can be used alternately, and producers should often pay attention to the effect of use and use them flexibly. 3. Light: lotus flowers especially like the sun, in the flower bud differentiation stage, if more than a week of rain and low temperature, the next batch of flowering will be significantly reduced. If in late June, sunny and hot less rain, hydroponic lotus will usher in full bloom. Hydroponic lotus flowers bloom more in the north where there is no long time for spring all year round. Light and temperature are two different concepts. The effect of light on lotus is manifested in three aspects: light intensity, spectral composition and light time. Temperature is how hot or cold an object is. In winter, the use of greenhouses to produce hydroponic lotus, the temperature can be used to meet the requirements of various heating methods, but the differentiation of lotus flower buds requires not only the appropriate temperature, but also the intensity of light. In winter, the sun is slanted, the intensity is weak, and the sunlight is absorbed by the plastic film, and the ultraviolet light in the greenhouse can not meet the needs of lotus flower bud differentiation. In the Huanghuai area at noon in the summer, the light intensity can reach 80,000 to 100,000 lux, and in the winter, hydroponic lotus production in greenhouses, the light intensity should be at least 50,000 to 60,000 lux. In order to ensure sufficient ultraviolet light, it is necessary to fill the light with fluorescent lamps, 100 square meters of greenhouses can be installed 40 watts of fluorescent lamps 16 to 20, cloudy days and night fill light. In addition, producers can strengthen ventilation at noon on sunny days to control the humidity at 70% to 80%. 4. Seedling precautions: The use of utensils, beds, nurseries and other facilities, the work of cultivating plant seedlings is called seedling. Time: Lotus seed seedling stage is a pure hydroponic process, which takes about three weeks before and after. Work: change water, divide basin, measure water temperature, prevent cold current. Venue: In a sheltered, safe environment. On the third day, most of the lotus seed cracks reveal green leaf buds, and new life is born and enters the seedling stage. After washing, dividing the basin and changing the water, it is placed in a place sheltered from wind and free from human and animal infestation. From then on, He Miao will receive sunshine and rain all day long. 5. Divided pot: according to the seedling density, divide the pot appropriately and timely to avoid the small lotus leaves to compete for the sun and crowded and wound. The sun is full, the little lotus seedlings are the same every day, the more you look, the more pleasant. Water depth to maintain 8-12 cm is good, the deeper the water, the longer the petiole. Too much density, rain and low temperature, lack of sunlight will cause the plant steep long, slender petiole delayed root. Pick up the rotten lotus seeds at any time, and record the number. After the first leaf unfolds, the petiole is 10-20 cm long, and it is normal for the leaf to float on the water. Leaf color some yellow-green, some dark green, some purple is a characteristic of variety diversity, but also a normal phenomenon. Seedling stage, do not fertilize the water! Lotus seedling growth depends on the mother and photosynthesis in the young stage, and has no fertilizer absorption ability. 6. Odd: It is to select a single plant that is particularly strange in some way from a large number of similar species. When talking about seed selection, Professor Cheng, doctoral supervisor of Forestry University, quoted the famous American breeders Burbank as saying: "In the realization of any ideal in plant improvement, the first factor is choice, and the last factor is choice." Choice is part of the ideal itself, part of every step towards it, part of the production process of every ideal plant." Little lotus money leaves water, is the beginning of strange work. Among the many leaves, you will always find some, even if there is only one unique individual, some leaf color is strange, some petiole is strange, some rhizome is strange... There are some strange that you and I can't think of, is the real strange! In the future selection, it is very likely to be eliminated, but please believe that it is born from hybrid seeds, and it is likely to be unique in the world.
