How can we grow iron? It is the more traditional chinese medicine in our country and has a very high medicinal value. It is ranked among the top of the “seven great sages of china”. Because of the harsh conditions in which the pebbles grow, low natural fertility and wild resource extraction, artificially planted iron pebbles are now the main source of supply markets. The following is a study of a key technology for high-yield production of iron and stone。
1 water management
The platinum is humid and should maintain a high humidity in the shed. The daily management principle of dry and wet watering, i. E. Watering the surface of the matrix after drying up, with a small amount of effort. Water is selected to be clean, alkaline micro-to-neutral, water volumes are suitable for basic application of the matrix, and often in a damp state. The water should be sprayed during the day and not in the rain shed. Maintaining relative humidity of 70% to 85% in the shed, subject to good ventilation。
During the summer, which is the period when iron platinum is growing fastest and growing most, the environment should be kept as wet as possible, subject to good ventilation, allowing for an appropriate increase in the number of sprayings, a reduction in the duration of the injections and the avoidance of watering at noon hours. After october, the iron platinum basically stopped growing and went into hibernation, and the number of sprayings should be gradually reduced. In winter, water should be watered at 10 a. M. In the middle of the sun, in order not to pour water, every three to four weeks, so as to keep warm and ventilated in the morning and at night, and to avoid watering in continuous rain and in cold weather。
2 fertilizer management
Prior to planting, corroded seed cakes were mixed in the planting matrix as the base fertilizer, with a ratio of 1:4 between the seedbread and the planting matrix. In the early stages of cultivation, which were dominated by leaf-based fertilizer, 0. 1 per cent of potassium phosphate and 0. 2 per cent of urea were applied interchangeably every half month. Fertilizers are generally applied over a long period of four months to october each year, and also when the iron platinum stops growing and goes into hibernation。
The second year after the planting began, the application of fertilizers was dominated by base fertilizer. Organic fertilizers, such as decompetent goat dung and vegetable cakes, are distributed evenly as base fertilizers, which are selected for one month before the flower blooms. After the flowering period the nutrients are replenished in time, 0. 2% of potassium phosphate folate is sprayed every half month for two months. In the summer, combined with growth, a 0. 1 per cent n-p-k = 20 ~ 20 ~ 20 is used to spray leaf fertilizers with micro-element fats every half month. The fertilization was stopped from the first three months of the harvest。
3 pest management
Iron platinum is growing in warm and wet environments, and unventilated sheds are highly susceptible to disease and pests. Prevention and control of pyrophagus pests should be based on the principle of “preventive and integrated management”, using preventive measures such as sterilisation of plant-based materials, cleaning of impurities around the site, strict isolation inside and outside the shed, and a combination of chemical control after the occurrence of the pest, prohibiting the use of highly toxic, highly residual pesticides and the limited use of some chemical pesticides. The maintenance of a clean, ventilated and relatively independent environment is the main method of reducing the incidence of diseases and pests。
The main diseases of the iron platinum are typhus, typhus molluscs and limey。
Zephyrosis, which mainly endangers the leaves, spreads in the black and brown spots during the onset of the disease, with the centre of the disease dying brownly。
Method of prevention: enhanced ventilation, timely removal of leaves and spraying of 0. 1% enzymes for treatment。
It is a bacterial disease that is infected from the root, with a softening of yellow, immersed in brown droplets and with a special smell。
Methods of prevention and treatment: improved ventilation, non-watering of culture matrix, timely removal of leaves and removal of strains; application of 0. 5 per cent of bordeaux or 200 mg/l for agro-syncin spraying。
Phenomena is mainly occurring in cold, high-moisture and poorly ventilated winters, first on the back of leaves, so that the whole plant is planted and then infected with the surrounding plant, which is extremely contagious。
(b) the timely application of 50 per cent of the fungible powder 1,500 times the liquid, or 65 per cent of the antimony powder 1,500 times the fluid。
The main pests are snails, snails, rat women and red spiders。
Snails and snails can be endangered throughout life, often eating young leaves. In general, during the day, underground, night-time creeps out of the activity hazard, which is heavier in rain. The worm crawls on the surface of a stone-planted plant, licks the tip of the stone, the leaves, grinds into holes, holes or breaks the stem seed。
Prevention and treatment methods: timely clean-up of the planting environment, removal of piles, reduction of dampness, spreading of lime around snails to prevent snails and snails from climbing into the larvae; where it has occurred, enticing insects with tetraaclyte granules from the field。
Rat women tend to die directly from the guillotine seedlings, tubers and underground roots, mainly because of the humid environment of the sheds。
Method of prevention: removal of excess bricks and weeds from the shed and maintenance of indoor cleaning; medical treatment in case of serious cases by rat women, with the option of 20 per cent to kill 2,000 times the permethrin, or 2. 5 per cent to kill 3,000 times the cream by the enemy, at intervals of 5-7d, with two to three successive sprayings。
The red spider is a mites pest. The worms are small. They are red. It's hard to find in the back of a leaf that smokes juice, but it's hard to find it when it's red spiders in april-may。
The method of prevention: first, see if there are red worms on the back of the iron platinum, if the platinum leaves are green and white, if the leaves are yellow and curly, and if the symptoms are described above, if the platinum is dangerous to red spiders, it is possible to spray thiomers of 0. 3 to 0. 5 degrees, three times each。
