At this critical stage in the prevention and control of the new coronary pneumonia epidemic, as well as in the cultivation and growth of iron platinum, both to prevent and control the disease, and to ensure quality, productivity and efficiency in the production of technical services. A technical guide to the preparation of spring tillage is provided to growers in time to inform them of the technical aspects of the spring production of barbed stone。
Iron platinum is the dry tuber of the rheumatoid iron pebble. From november to march of the following year, harvests were removed, impurities were removed, parts of the stubble were cut, heated and twisted into spirals or springs, and dryed; or a section was cut, dry or cooled, the former being known as “iron mackerel” (acoustics) and the latter as “iron pebbles”. Eligible planting period january-april. Land selection and whole land (1) tree-accumulation: selection of forest fractions with a density of 0. 6-0. 7; light-injection intensity of 60-70 per cent of open land; live tree growth, disease-free pests, thicker trunks, thicker tree bark, hard-to-fall woodland. Weed removal, cleaning of trunks. (2) accumulation: selection of limestone moss at a rate of more than 50% in mount caste, clean limestone surfaces, clean moss plants, transplanted to the rock surface and sprayed to keep moss plants alive. A suitable source of seeding, such as the geographical marker protection product “anronstones”, is a grouping of seedlings, which domesticate for 18 to 20 months, with five seedlings per bush, with more than three new seedlings and 10 cm lengths of troughs, with at least one thicker than 5. 5 cm. Plantation moved in january-march with a planting density of 3,000 series/acre. Cultivation: the cutting of weeds from forest land, the cleaning of trunks, the cutting of about 4 cm strips using sunnets and similar materials, and the binding of iron platinum seedlings bound to the trunks for at least 1. 5 years from the ground height of 1. 2-5 m. (2) accumulation: iron platinum seedlings are moved to fixed limestone surfaces covered with live mosses. 5 field management 1 month after transplantation, weeds, disease seedlings are removed from each other, and the gaps are replenished; the air moisture of the iron platinum planting base is maintained at 70-90 per cent, sprayed on a continuous sunny day before 10 or 16:00 and sprayed with leaf paste in april-september, 20-30 days apart; unsown plants can pick flowers and be processed into tea in a timely manner. 6 pest and pest management。
