Wai Niujia is a perennial herb of the genus Niujia of the family Amaranthaceae, also known as mountain amaranth and so on, and its dried root is used for medicine, with the effect of removing blood stasis and promoting menstruation, nourishing the liver and tonifying the kidneys, strengthening the tendons and bones, promoting diuresis and lymphatic flow, and inducing the downward flow of blood. The following is an introduction to the planting technology of hyssop.
Growth habit Wyoming hyssop is widely not in the country except in the northeast, often born on mountain slopes under the forest, suitable for warm and dry climate, not hardy, in the temperature -18 ℃ when the plant died. In the sticky * and alkaline * should not be planted. Selection of land preparation Choose * layer deep, fertile, well-drained in the loam * is appropriate, heavy soil is not easy to plant Huai Niu Knee. The previous crop to wheat, corn and other grass crops is appropriate; the previous crop for beans, peanuts, yam, sweet potato plots can not be planted hyssop. The knee is not suitable for continuous cultivation. Pre-planting mu uniformly into the fully rotted farmyard manure 3000 kg, urea 15 kg, calcium magnesium phosphorus fertilizer 80 kg, potassium sulfate 20 kg, conditions can be applied into the cake fertilizer 200-300 kg as a base fertilizer, ploughing 30 cm deep, watering moisture, harrowing, according to the 18-2 meters for the bed, bed length according to the terrain. Propagation Methods Seed Preparation: The best seed is Chifeng Niu Knee seed. Pick out the seed impurities, soak the seeds in water for 24 hours, filter out the water, dry and spare; planting can be used to withdraw the seed, strip seeding. Sowing: with a rake to sow the bed flat rake fine, will be treated seeds and fine river sand according to 1:4 mix, three times evenly spread in the bed, with a rake gently floor once, with a stone roller can be suppressed. Strip sowing strip width of 7 cm or so, row spacing of 20 or so, with a rake gently sowing once again, after sowing can be suppressed. Field management: 1, seedling management: after sowing. When the seeds began to sprout white buds when watering to promote the emergence of seedlings; when the seedling height of 5-10 cm, pulling weeds in the field, combined with the pulling of seedlings, plant spacing of 3-5 cm × 3-5 cm; seedlings removed from too small and too high seedlings, leaving the size of the same seedlings; when the seedling height of 5-10 cm, in the seedling density of seedlings out of the seedlings, replanting to the lack of seedlings in the broken ridge. Seedling replenishment method: with a small shovel with * up seedlings, in the lack of seedlings at the open 3-5 cm deep hole, will start out of the seedlings implanted in the hole, compaction, watering; 2, water and fertilizer management: should be depending on the growth situation, the general end of August, the seedling height of less than 20 cm, you can apply urea 2-5 kg per acre in order to facilitate the growth of young seedlings. The fertilizer can not be too much, otherwise it is easy to cause exuberant growth conditions, affecting the yield of the Wyoming hyssop. When the seedling height of 30 cm, 20-30 kg of urea per mu, seedling height of 30-35 cm, 60 kg of urea, 30 kg of calcium superphosphate, 30 kg of potassium sulfate; * soil watering when the water content is less than 20%. Wyoming hyssop is afraid of waterlogging, after the rain field water should be excluded in time; 3, hitching: due to improper mastery of the sowing period or improper fertilization will result in exuberant growth, affecting the late root downward elongation. When the phenomenon of exuberant growth occurs, available Kamakawa cut the upper 20 centimeters of Huai Niu Knee. Pest control Main diseases: 1, white rust: Symptoms: the victim leaf stop surface appeared many greenish-yellow spots, nearly round, 1-5 cm in diameter; leaf abaxial counterpart of the long many round or polygonal small white blisters, slightly elevated. For the sporocarp of the pathogen, rupture after maturity to exude a lot of white powdery material. The sporocarp pile is continuous, so that the disease leaves withered or early fall; Control: removal of disease residues; 80% Dasheng wettable powder 600 times spray 2 times, the interval period of 15 days; 58% methomyl manganese zinc wettable powder 500 times spray 2 times, the interval period of 1O days; 90% of the epidemic cream wettable powder 500 times spray 2 times, the interval period of 15 days; 25% of the methomyl wettable powder 800 times spray 3 times, the interval of 10 days. 2, leaf spot disease: Symptoms: the early stage of the disease spot is light brown, the junction of the disease and the healthy part is not obvious, mostly irregular or round, the late stage is dark brown, irregular shape, no halo, the junction of the disease and the healthy part is obvious, slightly sunken, the size of 0.3-0.8 cm × 0.1-0.6 cm. Microscopic examination can see a large number of sickle-shaped conidia; Prevention and treatment: removal of disease residues; 80% bicarb wettable powder 600 times spray 2 times, the interval period of 15 days; 50% carbendazim wettable powder 500 times spray 2 times, the interval period of 15 days; 70% metribuzin wettable powder 800 times spray, the interval period of 35 days. 3, wilt disease: Symptoms: the main stem base branching at the onset of the disease, the spot brown, serious, the spot around the stalk, resulting in wilting above the spot;Prevention: refer to the control of the leaf spot disease of cowslip.
The main pests: 1, beet nightshade: after the seedlings began to damage, the first hatching larvae cluster leaf dorsal, spitting net, in which to feed on the leaf flesh, leaving the epidermis, leaves eaten into the holes or scars, serious cases of leaf veins and petioles, resulting in the death of seedlings;
Prevention and control: the use of black light to kill the adults; poplar twigs tie to trap the adults; clear weeds; high efficiency Bt WP 1000 times spray 2 times; the use of black light to kill adults; Poplar branches tied to kill adults; high efficient Bt WP 1000 times spray 2 times; the use of Bt Bt WP 1000 times spray 2 times; the use of Bt Bt Bt Bt Bt Bt Bt Bt times spray 2 times; use 10% to eliminate spray 2 times, 14 days interval; 20% miman, 5% flubenzuron or 25% chlorothalonil l000 times liquid, 5% kadaike 1000-2000 times liquid spray, respectively, the interval of 10, 7, 10, 10 days.
2, bean turnip: like to eat young leaves, heart leaves, resulting in leaf deficiency affecting plant growth.
Prevention: 40% phoxim 1000 times liquid and 5% cypermethrin 1000 times liquid mixed spray.
Harvesting and processing: The harvesting period is also one of the important factors affecting the yield quality of hyssop. The best harvesting period for hyssop is from the frost to the winter solstice (from November to late January of the next year). Can not be harvested before the frost, otherwise the heart of hyssop blackened after drying. The use of manual digging for harvesting, the first to remove the ground part of the hyssop, leaving a stubble of about 3 centimeters, from one end of the field from the groove digging, try to avoid digging off the root.Primary processing: after digging and drying, remove the mud attached to the surface of the knee *, according to the size of the thick and thin heap; remove the knee of the adventitious roots and lateral roots, with straw according to the thickness of the knee were bundled into a handful of straw, hanging in the sunny place to dry, in the knee loss of 50% -60% of the moisture loss of the knee before attention to anti-freezing; to stay on the head of the reed 1 cm of the branch, to remove the overgrown portion of the branch; according to the length, thickness, color and lustre, in accordance with the provisions of the graded selection, excluding residual goods, frozen, oil; cut off the head of the reeds and hit the small stubble and hair tip; rope will be bundled into the knees, each 0.5 kg, leaving the knees stalk 1 cm, will be the upper end of the knife to flatten; spread out on the skip drying to dry; the bottom of the stack to be highly ventilated, smothered piles for about 10 days.
