This is not a model for quarries, as has been seen in many places. It's a water plant, which is also a watery plant. It likes wet, cool environments, which not only can be seen but also have good medicinal value. What's the method of planting? Let's get to know。
How many seedlings do you need to grow an acre
1. Crop density
An acre can be planted with 500 to 600 seedlings, with sufficient light, and stone platinum is grown at a distance of 30 x 15 cm, with two to three in each den。
2. Forms of reproduction
(1) cultivation: usually in september-october of each year, after removing the old yellow leaf from the plant, the plant is divided into 5 to 10 small strains, which are established and watered。
(2) root reproduction: usually carried out in the spring of each year, the root of the plant is extracted, the root of the plant is stubbed with stubbles and blades, which are then fixed at a range of 30 x 15 cm, with two to three plants in each den, which are then covered with tight soil pressure。
What is the method of planting the stone
The following techniques are used for stone cultivation in forest areas:
1. Land selection
(1) cultivation is generally chosen in the mountains where the soil is loose and fertile and the terrain flat。
(2) trees in the mountains can provide shades for the quarries, and they have good water storage capacity, which ensures sufficient water content in the surrounding soils。
2. Fertilizing the whole area
(1) the application of 1,500 kg of decomposition organic fertilizer per acre and of 50-100 kg of organic inorganic compound fertilizer。
(2) to till the land and flatten the compartments. It is about 1. 5 m wide, 50 cm wide, 50 cm deep and covers the surface of the section。
3. Deplanting
(1) choosing a two-year-old, mature and strong plant, divided into smaller strains with a bud, three stubs and roots to ensure smooth cuts。
(2) each 50 saplings are bundled and placed in a 5% potassium permanganate solution impregnated for about 10-15 minutes for disinfection. When disinfection is over, dry the back。
(3) a small plant is inserted into the soil at an angle of 30° in the annual autumn winter season. The seedlings of the small strains are found on the earth's layer, where the stem and root are inserted into the soil。
(4) after the planting has been completed, 100 mg/l 吲哚 acetic acid solution is poured to root。
Management
(1) replanted to march of the following year and kept dry and without water。
(2) march-april (premature) to enhance light and to promote the early birth of young children。
(3) started in mid-may, with proper shades and fat pursuits. Specific measures: water in the field canals is 10-15 cm from the surface and 50 kg water solubility is followed by a large amount of element fat and 2 kg trace element fertilizer, distributed five times per acre。
