1 sapling choice
1 seedling source. • introduction of soft-footed iron platinum plaster varieties from the north-west bizon autonomous region of yunnan. The plant is scrawny, small in its base, large in its upper middle, and not able to stand straight. A hard-legged iron platinum plaster was introduced from tsukshan city, guangdong province. The strain is vertical, has a strong stem, is long and has little difference between upper, middle and lower. Cultivation practices in liyang district show that soft-footed varieties drawn from the western bisumang autonomous region are more cold-tolerant and have a greater strength than hard-foot varieties in the city of tsuruyama。
2 age selection. Artificial planting of iron platinum is generally a form of training seedlings as a diversion material. In order to increase the rate of migration to life, it is necessary to domesticate the iron platinum group in the shed for a period of time before planting. It is important to note that the short time of domestication, the insufficient growth of seedlings, the emergence of new growth, the weakness and resistance of seedlings, the long time of domestication, the ageing and weakening of seedlings and the early planting of plants affect their yields and quality. Practice has shown that iron platinum seedlings that tame around 1a are growing better。
3 seedling standards. The standards for the domestication of iron platinum seedlings are four-and-a-five, five-leaf, five-leaf, five-and-a-half cm high, approximately 0. 3 cm diameter, robust and insect-free。
2 iron platinum platinum cultivation matrix formulation
Iron platinum cultivation is based on the need to be organic, air-gas-efficient and not perishable. Plantation matrix formulations and mass ratios used to plant iron platinum in the sheds are as follows: 1 m (peat) ∶ m (shell bark) = 2,404, planted in a flower basin; 2m (gold) ∶m (pine bark) = 3. 7, planted in a seedbed; 3m (romeda slag) ∶m (cabacus skin) = 2:5:3; 4100% pines, planted in a seedbed; 5m (gold) ∶m (pine bark) = 3:7, planted in a flower basin; 6m (polym) ∶m (polym) = 2:24:44, planted in a tub. The results of this experiment show that, after 1a's domestication, there are different formulations and planting methods of iron platinum. The growth of seedlings ranges from strength to weakness to strength of m (gold) ∶m (powl) = 2. 4:4. 4 (basket), m (gold) =m (pine) = 3:7 (basket), m (gold) ∶m (pine) = 3:7 (basket), 100 per cent (basket), m (pessal) ∶m (basket) = 2:4:4 (basket), m (losine) ∶m (scave) ∶m (basin) = 2:5:3 (bed)。
3 iron pebble seedlings
As a result of the incomplete development of seeds in the natural environment, the use of conventional seedling techniques has long age and high mortality rates, and production efficiency is low. The production of plant seedlings using the seeds of iron platinum, the tip of the stem, etc. Can effectively address the origin of seedlings。
1 using eight ripe omelets as an outer material. The whole breeding process requires sterile operation on the ultra-clean table of the sterile room. The octopus seeds are stripped with blades, packaged with sterile paper, disinfected in sterile bottles (75 per cent of alcohol is 30s, 0. 1 per cent of hgcl2 is disinfected 3-4min), then washed with sterile water about five times and vaccinated on disinfected cultures. After cultivation around 20d, seeds begin to fertilize, then through breeding, root culture, the sheds are domesticated into group seedlings for productive use。
2 the branches are used as outer material. A strong, insect-free branch was selected from the 1a-growing iron platinum plant in the shed, the blades and membranes were removed, then the mussels of the 1 to 2 cm left band were cut, washed in the fluid water, and 75 per cent of the alcohol was disinfected with 30s and 0. 1 per cent of the hgcl2 was sterilized with 6min. It then washes the tubing section about five times with sterile water, extracts the excess water from disinfected filters, cuts each end of the tubing to 0. 2 to 0. 3 cm, and inserts it into a sterile primary culture base, with about 15 per bottle. After 30 to 50 d of the first generation, one or two new sprouts were produced by the chief of the inter-sectional division, which in turn domesticated the seedlings for productive use through breeding and root training。
Group 4 training of seedlings for transfer
The transplantation was divided into spring planting (8 april) and autumn planting (20 september). The method of displacement consists of a single plant, with a single plant at a distance of 10 cm x 8 cm, and a plant with a range of 10 cm x 12 cm, with a range of 2 to 4 cm. The root is removed from the plant, the root is kept stretching and the depth of the plant is controlled at around 2 cm. Different types of seedlings are to be transplanted separately. The seedlings required for the cultivation of iron platinum are around 90 bushes per 1 m2, with more than 40,000 seedlings per 667 m2. Prior to planting, separate and purified iron platinum is added to the above culture matrix. After 1a has been domesticated and grown, the spring-planted and ploughed pyrotechnic saplings are growing better。
5 plantation management
Iron platinum is intolerant and suitable for growing up in a cold, wet, ventilated, pollution-free environment. As a result, yingyang city needs to plant iron and stone in facilities such as greenhouses and sheds, with the following points for plant management。
1 temperature control. Iron platinum is a subtropical herbivorous plant with a suitable growth temperature of 18-28°c, and the temperature in the shed should meet its growth needs. It should be noted that the temperature is too high in the summer (over 45°c) and that there is a need to increase ventilation, open curtains and keep temperatures below 45°c in the shed; appropriate measures are taken during the winter to keep temperatures above 5°c in the shed。
2 water control. Iron platinum is suitable for drying, usually with one water on the leaves on the third day, with a suitable wetting system in the post-vision shed to keep the base wet and air moisture in the shed around 80 per cent. The temperature rises in the first month and two months after the spring platinum rises, and should be activated several times, with a one-to-two-h shower at high temperatures (summer avoidance of midday spraying), maintaining a moist base, ventilation in the shed and spraying in combination with fatting to ensure that the gas roots grow well. The management of edible bacteria is largely consistent with that of iron platinum。
3 fertilizing. When the iron platinum is moved to 15d, 0. 1 per cent of the kno3 leaf is sprayed, and farm fat is applied to 40-80kg, depending on growth. In mid-october, 667 m2 of potassium phosphate was applied to 20 kg, with leaf spray; the following spring, a growth regulator, “hb101”, was sprayed with an increase in the rate of brevity, followed by a fertilisation of 40 to 80 kg, depending on the growth of 667 m2 trees。
4 winter management. The main task of winter management is to improve the temperature in the shed and to prevent the freezing of iron and stone. The main measures of winterization are as follows: 1 cold-resistant exercise to reduce the number of sprays, usually once every 15 d or so; 2 inner sheds with sufficient seals in greenhouses or sheds; 3 infra-red light bulbs to increase temperature at low temperatures; 4 heating blocks to heat up 667 m2 in general, 3 to 5 units per day, with about 4h per block burning and 2 to 4°c。
5 pest control. Iron platinum disease is more prevalent in hot, wet environments, where environmental management in the sheds is strengthened, ventilation is improved, humidity and temperature are properly controlled and biotechnology is used to combat diseases. Iron platinum cultivation is vulnerable to pests such as snails, snails, aphids, slashed night moths, etc. Aphids and slashed night moths suffer from malnutrition caused by acupuncture of iron and stone, for which 60 per cent of tea soap powder can be used to combat aphids and to lure slash moths with sugar vinegar。
6 collection
One to harvest. Iron platinum is growing 1. 5a and can be harvested in branches on the ground, usually from december to june of the following year. At this point in time, the plant is weak and contains the highest active ingredient. Iron platinum pebbles are picked and made suitable for iron pebble plumbing and micropowder。
Two flowers for harvest. The platinum platinum is of extremely high value, and the harvest took place during the flowering of april-june, usually dried on the second day of the flowering。
