Live corn broadcast methods mainly include open field live broadcast, live film mulching, live film pre-emergence, and live broadcast of summer corn stalks.
Live direct exposure of open field ground must be carried out when the ground temperature reaches 12°C, premature sowing of bad species, resulting in lack of seedlings and ridges, affecting yield. Fine soil preparation before sowing requires smooth ground and soil is soft and finely crushed. After applying basal fertiliser, make hoe, ditch or sow.
Overlaying mulching film directly on the mulching film has two methods: seeding the first film and first filming the film. The former method covers soil after sowing seeding, spraying herbicide, covering the film, and compacting the soil around the film. The method is suitable for different soil qualities and has the advantages of rapid temperature rise, emergence, and prevention of rain. As the plant grows and the temperature rises, the seedlings are broken in time. The latter method is on-site after covering the mulch with a plastic film. This method is only suitable for sandy loam cultivation.
The film must be seeded directly on the surface of the mulching film. The hole on the membrane should be small and tightly covered with soil to prevent air leakage and reduce the temperature inside the film. Compared with direct exposure to the open air, the live film mulching film has a good effect of heat preservation and warming, so that it can be planted in advance and ripened earlier; at the same time, it can also maintain the soil moisture and promote soil moisture, and promote the growth of corn roots. Weeds are not easy to grow under long-term cover conditions, eliminating the need for cultivating, weeding, and earth-cultivation operations, saving time and labor. Film mulching can also prevent birds, rats and other hazards, is conducive to the whole seedlings, Qi Miao, increase corn production. The fertilizer needed for the full growth period of corn is fully applied, and when the fertilizer is lacking, it can be drilled or grated.
Seed soaked with mulching film, soaked seeds of direct seeding corn, placed in the oven at 25 °C germination, germ 1 cm long sowing, seedlings at low temperature before hardening. Before the planting, the field is ready to be filmed with the mulching film and the soil moisture content is suitable. Immediately after sowing, the film was covered and compacted with soil to maintain the soil temperature. As the plant grows taller and the temperature rises, the membranes will be placed in a timely manner to prevent sprouting. Timely seedlings.
The summer corn board, the live summer corn board, and the live broadcast are corn seedlings that are sowed on the corn. After the harvest of wheat, there are no holes or lack of lyrics to make quail. Snow pods are sowed, herbicides are sprayed, and corn is set after emergence. Timely application of fertilizer, cultivating loose soil, to prevent the emergence of sterile seedlings.
Beeswax is obtained from the honeycombs of bees after the Honey has been removed by draining or centrifuging. The combs are melted with hot water, steam or solar heat; the melted product is filtered and cast into cakes of yellow beeswax. With detoxification, wound healing, tissue regeneration, pain relieving effect. Commonly used in the ulcer not healing, ecthyma erosion, ulceration of trauma, burn and scald.
