Site selection The site of Tianma should be selected in the hard soil, good permeability, not waterlogged slope-shaped land or flat land, the soil pH value should be between 5.5 to 6.
Digging ditches The ditch excavation specifications are generally 4 meters wide, 1.1 meters deep, 50 meters long (can also be with the terrain and planting scale). To turn the soil on both sides of the trench and piled up into a wall of earth, earth wall 2.1 meters high. If you can not hit the earth wall, you can use bricks inside the pile of soil into the inner wall (also known as retaining wall wall), the wall with wooden or cement poles to do purlins, every 40 centimeters across 1, purlins on the plastic woven bags, woven bags covered with wheat grass or straw 20-30 cm thick, wheat (rice) grass covered with anti-aging plastic film, plastic film and then covered with a layer of grass curtains, to raise the temperature, moisture, shade and rain.
Pre-seeding preparations Cultivation of jatropha are now square meters as a unit of calculation, so the preparation of materials also need to be calculated according to the square meter required. Generally per square meter to prepare a diameter of 3 to 10 cm quercus wood sticks 18 *** 30 kg, soaked in 0.25% ammonium nitrate solution for 12 to 24 hours, and in the sticks at intervals of 3 to 7 cm to cut the fish scale mouth of 1, *** cut 3 sides. Each square meter needs to prepare clean and non-polluting medium and coarse-grained river sand 0.25 cubic meters, river sand in the use of 6 hours before the best use of water rinse 1 time. Prepare 1kg of Quercus leaves per square meter, soak in water for 4 hours before use, drain off the water and prepare for use. Each square meter also needs to prepare 3 kg of Quercus branches with a diameter of 1.5 cm and a length of 3 cm, 4 bottles of honey ring fungus strains, 2 bottles (or 2 bags) of sprouting fungus, and 16 to 20 capsules of asparagus. There is also an important preparatory work is the sprouting bacteria and asparagus seeds are fully mixed. Operation first sprouting bacteria with a sharp knife cut into 1.5 cm wide small pieces (because the sprouting bacteria seed production is made with Quercus deciduous medium), into a clean basin, hand pinch the asparagus capsule to make the longitudinal seam cracked, and then shake the asparagus seeds in the basin in the sprouting bacteria, with both hands, mix evenly, every shake off a capsule mixing 1 times and the capsule pericarp pinch also sprinkled with the sprouting bacteria, mix evenly and wait for the sowing.
Sowing method When sowing, first in the bottom of the ditch on the ground paved river sand (also known as culture material and culture substrate) 5 cm thick, flattened, every interval of 5 centimeters placed 1 cut through the fish scale mouth and soaked in ammonium nitrate water quercus wood stick, per square meter placed 9 or so (15 kg), covered with 5 cm thick river sand will be soaked in water quercus wood leaves on the layer and patted; mixed with the seeds of asparagus sprouting bacteria evenly scattered on the layer of leaves, the leaves are mixed with the seeds, and then the seeds are mixed evenly with the sprouting bacteria. Spread evenly on the leaf layer, and then in the sowing of asparagus seed sprouting bacteria on the broken pieces of evenly spread 1 layer of leaves, and in the sowing of the layer placed cut through the fish scale mouth and soaked 0.25% ammonium nitrate water Quercus rods, so that the rods and the rods spaced 5 centimeters apart, per square meter of each layer * * * placed 9 or so, about 15 kilograms; and then placed in the fish scale mouth of the honey ring fungus species at the end of the two ends of the rods, and then put the diameter of 1.5 centimeters, the length of 6 cm Then put the small quercus rods 3 cm apart diagonally between the large quercus rods to guide the honey ring fungus on the rods; finally cover the river sand 5 cm thick. After sowing the second layer in the same way, cover the river sand 10 centimeters thick and pat it flat.
Management after sowing 1 week after sowing asparagus, can be in the asparagus beds lightly sprayed with water 1 time, 25 days later when the asparagus seeds have sprouted, the honey ring fungus has been and dasselwood sticks connected to the fungus needs to be sprayed with 1 time heavy water. Later to keep the sand moist can be, especially in July to August when the temperature is high, can not be heavy spraying, pay attention to ventilation, but can be sprayed into the air cool water to cool down. Into September, the temperature in 20 ~ 25 ℃, it is a period of vigorous growth of tianma, can spray heavy water to promote the growth of tianma. late October, the temperature gradually declined, in general, there is no need to spray water.
Harvesting The June sowing of jatropha, in order to expand the seed can be harvested in November of that year, transplanted, can also be harvested in March of the following year, transplanted. If you want to grow into a finished hemp, can be harvested or transplanted in November of the following year. The harvesting time of Tianma is best synchronized with the transplantation time. Tianma harvesting, the first layer of sand to remove, and then slowly lift up the sticks, pick out Tianma, the head of the parrot's beak will grow out of large Tianma (also known as arrow hemp), large white hemp (did not grow out of the parrot's beak is called the large white hemp), in the white hemp, white hemp and small hemp and rice hemp classification of the packaging in order to facilitate the use of separate. Then the second layer is harvested in the same way. After harvesting the arrow hemp or hemp processing into commercial hemp, arrow hemp some to do sexual reproduction of seed hemp, in the white hemp, small white hemp and rice hemp to do asexual reproduction of cultivated species.
