2. 2 sapling choice
At present, the main source of seedlings for the production of iron platinum is the seedlings. Cultivation should be based on the choice of a whole group of seedlings with the same colour, with the same size, heights of 4 to 5 c m, 2 to 3 roots, 2 to 3 c m, and the same color of the tubing。
2. 3 sapling treatment
To domesticate before a group of seedlings move, the bottle is moved 10 days in advance to a polytechnic seedling, the cap is opened on the 8th day, the 10th day cleans the small seedling culture base, drys to the roots white enough for transplantation。
2. 4 plantation matrix treatment
Plantation matrix is the key to high-quality and efficient cultivation, and the biological properties of iron platinum platinum require both good water protection and ventilation, and scale production requires relatively stable and more controllability. Now, there's a wide variety of matrixes that are used to grow iron and platinum, but the most used is pine bark, which is good for two fingers. The matrix is usually treated about a week before planting, and different matrices are treated differently. As far as pine bark is concerned, it can be spread on the concrete floor with tangills, concentrated disinfection about 10 days before planting, best disinfection with steam boils, chemically available microbicides such as polybacterium, methyltobutzim, white bacterial cleanup。
2. 5 plantation methods
It can be grown four seasons a year, in january, april, 810. The selection of pure, well-developed, even-sized and dry seedlings is embedded in the matrix, and it is not appropriate to cultivate too deep, otherwise it is easy to cause rotten roots. The stem base of the seedlings should be completely exposed, and the roots should be stretched. It's made of three or four saplings per sap, density depending on the duration of the planting, short 10 cm, long 15 cm。
Management of cultivation
6. 1 shrimp management
When planting a seed, do not plant too deep, but the roots must be closely connected to the matrix, so that the seed is standing up. The first day of planting, the foundation watered, and within a week of planting, not watered, ensuring that the seedlings did not fall. One week after planting (the seedlings have not yet taken a new root), it is best to keep air moisture at around 90%, which is conducive to survival. 1 air moisture is controlled at about 70 % and 80 % after a week to induce new seedlings to germinate。
Long-term management
4 in january/july, the iron platinum is split and growing at a fast pace, with particular attention to maintaining air moisture above 08, but not water; the amount of water is also different from season to season. The light needs to cover the sun, to prevent the sun. Especially at high summer temperatures, the facility sheds open cooling systems such as wet curtains, wind blowers, sprays, ventilation, etc., to control the temperature of the sheds to the point where the iron pebbles are suitable for growth. When the temperature is low in the winter, the facilities can be sealed, and when the temperature is below the normal growth temperature of the platinum platinum, the temperature can be increased in the facility by heating in a variety of ways to prevent the freezing of the plant。
2. 6. 3 winterization management
In winter management, which is mainly temperature-preservation, the technical key is that the winter iron platinum is largely out of growth, less water is required, and the water content of the matrix should not be too high, with the matrix having a normal water content of less than 40 per cent, air moisture of 60 per cent and 70 per cent, usually sprayed once every 2 weeks. Pre-winter periods are subject to anti-frozen exercise and proper wetting。
2 7 fertilizer management
Ironstone is humid and should maintain a high humidity in the shed. The watering principle is dry and wet, i. E. When the surface of the matrix is dried up, the water is watered in small quantities. The choice of water quality is clean, the acid alkaline micro-neutrality, the water volume is suitable for basic application of the matrix, and is often in a damp state. The water should be sprayed during the day, 70% wet in the shed and 80% wet in the summer. In the early stages of the cultivation, it was dominated by leaf-leaf fertilizer, with 0. 05 per cent of the amount of high nitrogen fertilizer sprayed every 7 to 10 days. When a plant is planted, it increases organic fertilizer, such as bean cakes and peanut fertilizer, which usually lasts for a long period of 4-1 october of each year, and when the iron pebbles stop growing. Pesticide fertilizer is banned from the first three months of the annual harvest。
8 pest management
It's warm and wet, so it's prone to disease and pests. The main pests are molluscs, brown spots, anthrax, mirex, clams, snails, red spiders, etc。
2. 8. 1 softness
(b) in serious cases, the whole rotting body is wet. Prevention and treatment methods: to increase temperature, regulate water and ventilation; to prevent foliage water and rainwater washing at night; in the event of a disease, a combination of 10 times the agro-chain cortex and 10 times the enzymes can be used。
2. 8 2 brown spots
It's hot and rainy. The symptoms are a large number of black and brown spots on the leaves that lead to the death of the plant. Methods of prevention: increased phosphorus, potassium fattening, rational watering, application of 80 times more polybacterial fluid in the early stages of the disease, and 5 times more liquid in dyson zinc. The use of pesticides should be based on the principles of low toxicity, low residue, efficient prevention and integrated treatment。
2. 8 3 anthrax
Most of them occur in spring and autumn. The main symptoms are: dark brown or black spots in the leaves, black stripes in a circle from the inside to the outside, and severe infections of the tubers and new strains. (b) 65 per cent of dyson zinc 60 times one 80 times more liquid, anthrax 8 0 ~ 10 times more liquid, fungus 80 0 1 0 times more liquid and methyl tobuzin 10 times more liquid were sprayed at the beginning of the disease. In serious cases, 10% of the world's high water spray can be used for control。
2. 8 4 arrays, snails
Most of them occur during the hot, hot and wet seasons, which mainly endanger the seedlings and leaves. Prevention and treatment: take care of indoor and outdoor sanitation, clear weeds, regularly sprayed lime, targeted drugs such as meta, snails, etc., and can also be used to kill by hand, bait. Boobs
2-8, 5 guilders
It was born on the edge or on the back of a leaf, and in late may, it was hatching. Prevention and treatment methods: 40 per cent can be used for emulsions of lactation of fruit at 10% or 50 per cent of mara parathion at 10%, or for the burning of old branches with concentrated mirex。
2. 8 cedars
More often in dry seasons, more often on the back of the leaf, more rapidly growing, more timely processing, less spreading. Targeted drugs are kit, avimactin, good homework, etc。
Collection and processing
In the winter 12th to january of the following year, when nutrient accumulation peaked, it was the best harvest period for short-term cultivation; in the long-term planting, in the spring of january, a new sprouts were harvested from the root of the old, with the head of the estate at the time of harvest, 2 to 3 centimetres. The day after the harvest, the plant could not be watered, so that the wound could rot in the wet state and die of a sprouts. The pick-up stem is sifted by grade, and leaves and washing can be processed for maple. They are by-products of the platinum, which can be sold for cooking; they can also be harvested and cleaned and dried in time for tea and drink. It's not appropriate to pull all the roots up at the time of harvest, to use scissors to cut, to cut, to cut, to cut, to cut, to keep growing。
Removes the harvested branch from its roots, curvatures, and strips it off, cleans it up, drys it down 60°c; after decorating the water, the hand scrolls on the baking side become spiraly cylinders, with straw straw or oxen-skin strips added to it, the tattering material removed from the ventilator after a few days, then baked to dry on the carbon fire, with yellow on the surface。
